This is a breaking news for PSP firmware 2.5/2.6 users like me. Have you ever heard someone said “It is impossible for PSP 2.5/2.6 to be downgraded!!”, “haha, too bad dude, you got a stupid 2.5/2.6 PSP that cannot be downgraded and play ISO UMD”, “You will be regret if you plan to go for white PSP 2.5/2.6″. That is what we heard in the past time.
Now PSP 2.5/2.6 can be downgraded to 1.5 except PSP that having TA-82 motherboard. I have downgraded my White PSP with Factory firmware 2.5 to 1.5 successfully 2 days ago, right after Dark_Alex released final version downgrader along with Mathieulh and Yoshihiro. We also give BIG THANKS to Hitchhikr who make exploit possible in PSP 2.5/2.6 via GTA eLoader. After Hitchhikr successfully unlocked PSP 2.5/2.6 kernel, beta version of downgraders are released in short time. We shall thank to those brave PSP users who had been trying to downgrade their PSP during Beta version. There are some people who bricked their PSP during downgrading their PSP. So sorry about them and we must appreciate those brave guys who point out the failure reason for developer to improved the beta downgrader.
As you noticed the following date are when the Kernel was unlocked and downgrader was released. Downgrader is released within A WEEK time after Kernel is unlock!!!
27th June 2006 - PSP 2.5/2.6 Kernel Mode Unlocked
30th June 2006 - Downgrader V5 Beta Released which having more than 90 percent success rate.
2nd July 2006 - Downgrader Final Version Released < -- I'm using this final version to downgrade my PSP 2.5

Faisal’s Guide to Downgrade your PSP from 2.71 to 1.5
| 2.71 to 1.5 GuideHi everyone,
First of all I would start by introducing my self, My name is Faisal from Saudi Arabia. I am doing this step by step guide which is part of my quest to 1.5. Now some of you may find this lengthy and boring. Well…. The idea behind writing this in such detailed way is to ensure I cover all the topics that are required to achieve a successful 1.5. Also this is intended for Noobs like my self who ask for more eachtime. So here it goes: What PSP I have: I bought my PSP 1 month ago. It was a factory 1.52FW PSP-1007K WS259 “C”. This is the Taiwanese version. For those of you who don’t know the previous versions of the Software downgraders were unscuccessful with a PSP-1006 & 1007 (Asian versions). But that’s not the case with Dark Alex’s Easy Full Downgrader 2.71>1.5 by XTRUSION. History of UPGRADE Before getting 1.5! As mentioned above, I had a factory 1.52FW, so in order to play the new games I upgraded to 2.60FW using the GTA disc FW upgrader that came embedded in my GTA. It is a US version of GTA (PATCHED ONE!!!!). believe me the reason I decided to use the new 2.71 Easy Full DG is because I couldn’t find the GTA unpatched version here in Saudi. For those who don’t know the previous Dark Alex DG 2.5/2.6 required an UNPATCHED Copy of GTA LCS (it is as hard to find these days as a factory 1.5… TRUST ME). (How to tell if you have a UNPATCHED …. The ONLY way is to put the UMD in, if it asks for a version 2.0 upgrade it is UNPATCHED otherwise it is PATCHED. So on 1st September when I came to know about the new downgrader 2.71 > 1.5 I went to the dl.qj.net site and downloaded a copy of the 2.71 FW to upgrade. Successfully upgraded to 2.71 I believe it was the North American version. So once I had the 2.71 I was all set to get 1.5. Checks before downgrading THIS IS THE MOST IMPORTANT PART OF MY POST…. READ CAREFULLY. All the information here will help you decide weather you qualify for a Downgrade or not. Pls. Pls. people don’t flood forums by posting 100s of questions with out doing your home work…. As for my self…. I studied about a month from various forums….. trust me the knowledge and person experiences of others really eased my quest…. Anyways…. This is a list that should be followed A-Z no if’s and but’s : 1) Dark Alex Easy Downgrader 2.71 > 1.5 by Xtrusion is ONLY for 2.71. The Actual Downgrade: Ok, so after you’ve gone through the above check list, you’re good to go,,,, although the most important thing that you need to understand is : “You’ve been Warned !!!!! This could potentially brick your PSP. Your best chances of doing it right is if you follow the above list and ensure that you’re ready to accept the outcome, Don’t blame anyone…. IT IS YOUR DECISION.!!! • Connect you PSP to the power adaptor. Special thanks to Dark Alex, Yoshiro, Fanjita, Xtrusion and other developers who made this so easy and possible. Also special thanks to POX & RAGGABLE of PSPHACKING101.com. You guys are unbelievable.. Watched all your 18 episodes… awaiting the next one anxiously. So in the end guys, trust me it is not difficult at all….. it is really easy with the voice interface. And the process is only 5 minutes total.. so don’t deprive your self of the wonders of 1.5.. HOMEBREW, ISOS, DEVHOOK here I come!!!!!!! Good Luck to all.!!!!!! |

r u 100% sure????????? how do i find out if my psp is TA-82 or not
jackdripper:
Ya. I’m very sure. during the Downgrader V5 Beta Released, there was already 93%++ success rate for downgrading PSP 2.01/2.5/2.6 to PSP 1.5.
To find out whether your PSP is TA-082 motherboard which cannot be downgraded now, refer to this link.
My white PSP also have printed number on the circuit board but the number is located at opposite side(left). If yours also located as left side, it would be okay, its “IC6001″ and so glad that it is not TA-082. So i still able to downgrade my PSP.
Just follow exactly the steps. fully charge your PSP and plugged with power adapter. Mostly will be downgraded successfully. I’m also not dare to take the risk at first until the Downgrader Final Version Released
note: Any how, as usual, try it at your own risk.
hey man there says something about a folder from a 1.5 psp user, where am i gonna find a user like that?? plzz someone help me…
i really am desperate, i have a 2.01 psp and i figured that if i update to 2.5 i can downgrade it from there, i havent updated yet so plz can someone help me, my email is shrody_cat_napper@yahoo.com plz…
hey man! a friend of mine just bricked his psp (and it was the one with IC6001 on the other side..)
I got 2.01 and same “ic6001″ on the other side… What should i do? how many psp`s did u test this thing on?
pls e-mail me “rebedeub@yahoo.com”
Stf:
ya, u need someone who has PSP 1.5 firmware to obtain some file from 1.50 updater. Because these files are copyrighted and illegal to share. That’s why you saw from many website/guide about asking you to get it from someone who own PSP 1.5 firmware. However, Internet unable to avoid Internet user to share this file over the net.
The downgrading process is really simple but you have to aware that anything you do is at your own responsibility. As long you get the DOWNDATER folder from PSP 1.5 or from your friend, then you are able to downgrade your PSP from firmware 2.5/2.6 to firmware 1.50.
At your PSP 2.5/2.6:
again: as usual, try it at your own risk.
RB:
Dude, so sorry that hearing a bad news from your friend.I have no comment bout that sad story. Of course i’m only tested one PSP and that’s my only one PSP. I just like you guys only can afford one PSP.
As i read from Internet, PSP 2.01 should upgrade to v2.5 and downgrade. I only tested my while PSP which has factory firmware 2.50. And of course I was very afraid that I brick my PSP during downgrading.
What I can say is a very GOOD LUCK to you brother. Only try it after you make up our mind.
oh ya, after i downgraded my PSP 2.50 to PSP 1.50 I had tried to upgrade my PSP 1.50 to PSP 2.0 and downgrade it to PSP 1.50. It’s working fine for me and i felt very relief. It is recommended to perform such extra task that I read from Internet.
My downgrading process:
1) PSP 2.50 —> PSP 1.50
2) PSP1.50 —> PSP 2.0
3) PSP 2.0 —> PSP1.50 (SUCCESS!!)
I would suggest you guys read all comments from PSPUpdates 2.5/2.6 Downgrader FINAL Released! Post. Currently there are 923 comments. LOL hope you guys see the big picture there.
hey belive or not i found my psp 1.5 files on bitcomet and they worked like a charm, besides i done the same process like u with the downgrade and it worked, now i have another problem, aaaa… im kinda newbie do can u helpp me out with some pointers, cause i have an iso image of FIFA STREET and i dont know what to do with it
i am with the 2.01… what do u mean with the “Wab Version Changer”? i didn`t get that part…
and.. what do u recommend? upgrade to 2.5 or 2.6?
Stf:
There are few homebrew application/tools/utilities that allow us play UMD ISO game. Certain game only can be play by certain homebrew application/tools/utilities.
You may visit this link to know which application/tools/utilities that you need to play your downloaded UMD ISO game. PSP Compability List
Mostly new game will be using DeviceHook and currenty its version is 0.46. Try to download from torrent site.
DevHook V46 Ultimate Installer or
DevHook 0 46 FULL Installer by BADR1X
There are much more amazing homebrew application for PSP 1.50 user.
RB: Wab Version Changer is to change the firmware version logically. I doubt most of PSP 2.5 downgrader can be downgraded to PSP 1.50 directly without the need to use Wab Version Changer. For me, I didn’t use that. You may google for more detail about Wab Version Changer if you want.
I would recommend you update your firmware to PSP 2.50 will do since you can be downgrade from PSP 2.50 so that’s no point to make it PSP 2.60
Hi all, im Faisal from Saudi Arabia. I have a factory 1.52 psp that i updated to 2.60 using the GTA (US) FW update that is coming with the game. Now i have a 2.60 PSP. I really want 1.50 and been reading about the XTRUSION easy 2.60 > 1.50. I obtained the copy of US EBOOT 1.5 also. NOW THE QUESTION: I have a PSP-1007 (Taiwan) version, it is not TA-082 since no writing on the right, only some letters on the left. So can i downgrade a PSP-1007 with this downgrader. You may know that earlier software downgraders didn’t worked with PSP-1007. So pls. pls. confirm to me the situation and i will post the results. Thanks to all you guys for sharing valuable information here.
Faisal: I’m not very sure bout PSP-1007 whether can be downgraded, as far as i seen is always mentioning bout TA-082 which cannot be downgraded up to now. I can’t promise much for your downgrading task. For safety issue to avoid your PSP from bricked, maybe you should try to gather more information bout PSP-1007 and gain more confident before doing it so.
I tried to google PSP-1007 downgrade but it seems not much information. I think because most people didn’t really named out their PSP region version as me. As i said, i also spent few days to make up my mind for downgrading.
Before you do so you should think bout the consequence of bricked, like “i already decided to buy another PSP even it is bricked.”, “I can take the risk and nvr blame someone else cause i’m the one who decided to do so.” or come to the worst “I won’t play that damn PSP because its so easily bricked.”. All the best dude.
Thanks skyfish for your reply, you rock man!. I’ve been doing my homework, tryin to dig more info and stumbled upon a downgrade video of a Latino guy who bought his PSP-1006 from Hong Kong (You may know that 1006-1007 are almost identical). And this guy downgraded without a hitch. So i guess this may suffice my first question. However now the new question is, i downloaded the Easy Downgrader by XTRUSION from psp-hacks site, this is the FULL version, and as i red this does not need you to have a 1.5 PSP handy, cause all the 1.5 files are already in the Full downgrader. Could you confirm that? and also if it does contain the E-loader as well, meaning all i have to do is format memory stick and run the damn thing and it’ll do the rest.?
Finally last question: I am not much tempted with emulators for the first generation consoles like the SNES, Genesis etc… rather the only reason i wanna downgrade is to have the ability to play ISOS. I want to know are they availble for download from the net?? i know it may be an ILLEGAL question? but just a simple answer won’t charge us…
Also tell me did you use the Easy downgrader Full version also to downgrade??
Once again, thanks for your reply…. later..
Faisal:
ya, the Easy Downgrader full version is already included DOWNDATER folder (which is obtained from PSP 1.5). All you want to do is get yourself a GTA UMD and follow the instruction of Easy Downgrader installer. You do not need PSP 1.5 now since the DOWNDATER is provided. And yes, it include e-loader as well. All you have to do is get a memory stick which has at least 32MB memory space. As the installer go, it will copy needed files to your PSP memory stick and the instruction of Easy Downgrader is simple and complete.
After you downgraded to PSP 1.5, you can do lot things with your PSP. Like streaming video from your PC to your PSP, listen to stream radio, play ISOs, play SNES, Nintendo 64 games, GBA, bla bla bla. You even can write your own program to run on PSP that is what they called “HOMEBREW”.
Of course , UMD ISOs is illegal. However, there is very hard to control the information/resource over the Internet. Hence we have bit torrent introduced to the world now and it allow me to download lot of PSP ISO from torrent sites. I normally go to http://www.mininova.org which there is a PSP category of torrent. Or u can search the particular PSP torrent from http://www.isohunt.com or http://www.thepiratebay.org.
And for the updates and information bout PSP, you can visit http://www.ps2nfo.com and pspupdates.qj.net.
I’m not using easy downgrader because my brother has PSP 1.5 so the DOWNDATER folder and files i extracted myself via my brother’s PSP. Since it is the same as the one provided by Easy Downgrader so i believe you can proceed with Easy Downgrader.
Hope to hear the good news from you, friend. If you still have any question, just raise out and i will try my best to help you. Just afraid that maybe my response is slow.
All the best dude!
hey skyfish, can’t say much about how important your feedback is to people like myself who are some how not well versed with all the crazy stuff round the clock…. anyways you last message and some further study over the net has helped me make up my mind and i’m gonna go for it….. the only step that is halting the downgrade is having GTA….. i mean the UNPATCHED version of GTA. I bought it as soon as i got a PSP however the darn thing’s PATCHED…. URGHHHHH!!!!!! Been tryin since to locate a human who can tell me that he has it…. You see the problem here in Saudi is we don’t have any rental system, also the market is not so huge… but still GTA sells like crazy… therefore unable to find a single copy of the old version… now i guess the only bet is to look around at EBAY or stuff…. but man !!!!! there are some thugs there !!!! saw some ads people asking for 60+ bucks for an old version….. any suggestions..?
Later.
Ok, can somebody please help me. I have been searching forever and i can not find neither the easy downgrader Full version with the downdater folder, nor the 1.50 downdater files alone. Could somebody please give me a link for the full version of the downgrader or better yet could you email me the 1.50 downdater folder at Sleeping_Insomniac@adelphia.net i hate to be reduced to begging on a forum like so many others, but i’m at the end of my rope. please help.
Disregard my last post, i was able to get the downdater folder by running the easy downgrader app but saying my psp is an empty folder so it just extracted the files there, thanks anyways

Following is my step by step guide that i made for all noobs like my self who had so much problem figuring this out. Again thanks Skyfish for your support. keep up the good work dude….So here it goes…
2.71 to 1.5 Guide
Hi everyone,
First of all I would start by introducing my self, My name is Faisal from Saudi Arabia. I am doing this step by step guide which is part of my quest to 1.5.
Now some of you may find this lengthy and boring. Well…. The idea behind writing this in such detailed way is to ensure I cover all the topics that are required to achieve a successful 1.5. Also this is intended for Noobs like my self who ask for more eachtime. So here it goes:
What PSP I have:
I bought my PSP 1 month ago. It was a factory 1.52FW PSP-1007K WS259 “C”. This is the Taiwanese version. For those of you who don’t know the previous versions of the Software downgraders were unscuccessful with a PSP-1006 & 1007 (Asian versions). But that’s not the case with Dark Alex’s Easy Full Downgrader 2.71>1.5 by XTRUSION.
History of UPGRADE Before getting 1.5!
As mentioned above, I had a factory 1.52FW, so in order to play the new games I upgraded to 2.60FW using the GTA disc FW upgrader that came embedded in my GTA. It is a US version of GTA (PATCHED ONE!!!!). believe me the reason I decided to use the new 2.71 Easy Full DG is because I couldn’t find the GTA unpatched version here in Saudi. For those who don’t know the previous Dark Alex DG 2.5/2.6 required an UNPATCHED Copy of GTA LCS (it is as hard to find these days as a factory 1.5… TRUST ME). (How to tell if you have a UNPATCHED …. The ONLY way is to put the UMD in, if it asks for a version 2.0 upgrade it is UNPATCHED otherwise it is PATCHED.
So on 1st September when I came to know about the new downgrader 2.71 > 1.5 I went to the dl.qj.net site and downloaded a copy of the 2.71 FW to upgrade. Successfully upgraded to 2.71 I believe it was the North American version. So once I had the 2.71 I was all set to get 1.5.
Checks before downgrading
THIS IS THE MOST IMPORTANT PART OF MY POST…. READ CAREFULLY. All the information here will help you decide weather you qualify for a Downgrade or not. Pls. Pls. people don’t flood forums by posting 100s of questions with out doing your home work…. As for my self…. I studied about a month from various forums….. trust me the knowledge and person experiences of others really eased my quest…. Anyways…. This is a list that should be followed A-Z no if’s and but’s :
1) Dark Alex Easy Downgrader 2.71 > 1.5 by Xtrusion is ONLY for 2.71.
2) Don’t use it on 2.70 or 2.80. IT WILL BRICK. For 2.70 owners upgrade to 2.71 first.
3) Owners of TA-082 IC1003 (text is on right, if on left behind UMD casing no probs as in my case it had IC1009 behind UMD casing). Don’t do it if you have TA-082 MB, it’ll BRICK.
4) DO NOT forget to plug the power cord all through the process. VERY IMPORTANT.
5) I used a 1GB Sandisk Pro Duo MS. Formatted using my PSP. (u can use 32MB as well).
6) Ensure you use the FULL VERSION of the DG 2.71 > 1.5 using. Don’t use the LITE version. The Full does the job for you, don’t have to worry about placing files and folders in the right places.. The full version is the best way to go… YES It includes the 1.5FW dump… no need to ask for links anymore. Just get the full version and you’re good to go. I got it from RAPID SHARE. It is an EXE file 15.6MB has voice acting funny hehe… especially the “PSP” one….
The Actual Downgrade:
Ok, so after you’ve gone through the above check list, you’re good to go,,,, although the most important thing that you need to understand is : “You’ve been Warned !!!!! This could potentially brick your PSP. Your best chances of doing it right is if you follow the above list and ensure that you’re ready to accept the outcome, Don’t blame anyone…. IT IS YOUR DECISION.!!!
• Connect you PSP to the power adaptor.
• Format your memory stick using PSP.
• Connect to the PC using USB cable
• Run the Dark Alex Easy DownGrader 2.71 > 1.5
• It will ask you if your PSP is compatible or not. Proceed to the next screen and identify drive letter.
• Next the program will start copying the files on the MS for the 1.5 dump.
• Once done, it will ask you to disconnect from USB and go to Photo to run the DG.
• VERY VERY IMPORTANT: It may not run on the first try due to an instability of the TIFF exploit. For my case it took 5 tries until it Finally worked. Just remember don’t worry if you go to Photo and screen FREEZES. This means you need to restart. Don’t worry… you restart manually by holding the ON switch for 10 seconds. You’re still at 2.71 NO HARM to your PSP. According to Dark Alex the code will either execute Fully or Not at all. So don’t worry. I also encountered memory still flashing for about 20 seconds but no red screen. Also one time out of the 5 tries MS light just stayed ON until I manually switched the PSP OFF.
• REMEMBER you are only looking for a FULL RED SCREEN, this is the point of no return. Once you get the RED Screen just DON’T TOUCH ANYTHING!!!!! It should flash for about 2 Minutes and then your PSP will go BLACK. Again give it another minute don’t RUSH!!! Now the software will advise you to switch ON and see the BLUE ERROR screen.
• Just switch it ON using and you will get the BLUE Screen with a lot of text saying “System setting are corrupted press “O” to goto default settings. Now press the O button and wait for the hand of fate…………… You’ll get a reboot and it’ll ask you to set date time etc…. once done you will have a 1.5 FW… YAAAAAAAAAYY.
Special thanks to Dark Alex, Yoshiro, Fanjita, Xtrusion and other developers who made this so easy and possible. Also special thanks to POX & RAGGABLE of PSPHACKING101.com. You guys are unbelievable.. Watched all your 18 episodes… awaiting the next one anxiously.
So in the end guys, trust me it is not difficult at all….. it is really easy with the voice interface. And the process is only 5 minutes total.. so don’t deprive your self of the wonders of 1.5.. HOMEBREW, ISOS, DEVHOOK here I come!!!!!!!
Good Luck to all.!!!!!!
i found this site i think its the same faisal can u tell me that this is the correct download thx
*You have to update to 2.71 y and then use its downgrader*
Step 1 Download this and copy it to PSP/GAME/UPDATE
Step 2 Download 2.71 downgrader
http://psp.xtrusion.es/content/singta.htm
my psp doesn’t say “IC6001″ on the back does this mean it can’t be downgraded
Faisal:
Welcome to PSP 1.5 world~! I really feel glad that you finally get your PSP to 1.50. And i’m very appreciate that you shared your brilliant experience of downgrading your PSP from 2.71 to 1.50 with detailed explanation.
So, I believe you start to get the joy of 1.50 now rite? hehe
michael:
If your “IC6001″ number is located at the same side as mine. I think it can be downgraded. Please refer to my earlier comment for more information. Good luck dude.
abishek:
Ya, dude. It’s the same address as what we mentioned. just download the FULL version. Good luck.
by psp doesn’t have “IC6001″ on either sides do i need to have this model to be able to downgrade
michael:
Oops, I thought your PSP is having “IC6001″ number on the back. Sorry that I didn’t read your question properly.
The answer is “NO”. If your PSP does not have “IC6001″ on the back, it doesn’t mean that you cannot downgrade your PSP to 1.5 version. As long as the motherboard of your PSP is not TA-082, you are safe to downgrade your PSP.
If there is no number on the back of your PSP, then your PSP is not TA-082 motherboard. It means you can downgrade your PSP.
Refer this to check whether your motherboard is TA-082.
Check TA-082 Guide
I have a psp 1000 with a IC6001 on the left hand side when looking at it with the psp logo upright. It is a 2.6 v Am I right that I need a usb cable and a memory stick of 32mb+? I have all the websites that I need to get my downloads from but what steps do I need to do beforehand, Do I plug in my psp into the pc with the memory stick in and formatted? Once I have downloaded my upgrade to 2.71 what do I do next?I think abishek said that I need to save it to psp/game/update, then do I follow what faisal did with the downgrader 2.71 -1.5?
Hi there,
Recently I became the proud owner of a white PSP 1000KCW with version 2.60. I’m thinking of downgrading to 1.5 but I’m very clear on how to do it as I’m quite new to PSP. I know that there are different version of downgrader program around, so I’m afraid I might brick my PSP! And I dun hv the GTA umd.
So can let me know what are my options and which version of downgrader shld I use?
I have also heard that after downgrade to 1.5, we can still emulated 2.71, is it true?
koi:
Ya, you will need USB cable to transfer file needed to your memory stick. 32meg memory stick is enough. You can use larger capacity memory stick if you have one.
You can just format your memory stick from your PSP, it doesn’t matter.
Faisal done a very great job here by posting his guide with his own experience. You can follow Faisal’s guide, it is very detail. We shall give him a great clap.
So you can just follow his guide to get you to PSP 1.5 world. As usual, good luck, and welcome you to PSP 1.50.
Dickson:
You can refer to Faisal guide which was posted comment here. Faisal gave us a very good guide and I believe it can help you in downgrading your PSP.
You doesn’t need unpatched GTA UMD to perform downgrade now. What you need to do is to upgrade your PSP to 2.71 firmware. And downgrade from 2.71 to 1.50.
And you are right, from PSP 1.50, we can emulate 2.71, 2.50 firmware PSP with DevHook. So the answer is “It is true”.
You can always refer to http://www.ps2nfo.com and pspupdates.qj.net.
Hi skyfish,
Thanks for clearing my doubts and after reading Faisal’s guide, I’m confident I can downgrade to 1.5 too! Great job guys!
The only hurdle is how to upgrade to 2.71, I’m having a jap set, must i goto jap psp web to upgrade?
Dickson:
You can upgrade to any version of 2.71, it doesn’t matter which region you are. Mean you can upgrade to 2.71 with American/Europe update. It doesn’t affect your downgrading.
after i domwgrade my psp using DOWNGRADE I brick my psp and dont work at all , please help me ANY SUGESTION THANKS..
Just like Ragna, I also have two codes on my motherboard. IC1003 on the upper right and IC6001 under the UMD case on the left.
I’ve searched forums and stuff and can’t find anything about the two codes, except me and poor Ragna.
I upgraded from 2.6 to 2.71 and I need to know if I can downgrade safely to 1.5 without bricking using . If possible I’d like to do it without the GTA UMD.
Can somone please help and tell me if I have the dreaded TA-082??? If you want proof, I’ll send you a pic, email me at shukron3@zahav.net.il

I have downloaded the 2.71 upgrader but I do not know what to do, to know if I have upgraded to 2.71. What do I do once I have downloaded to my psps. I there something I need to press on my psp to launch it? I know I have dowbnloaded it as my pc shows the file is on the files in my psp.
Hi,

1) upgrade to 2.71
2) downgrade to 1.50
I download from hxxp//psp.xtrusion.es full version
thanks all
koi why would you upgrade to a 2.71?
wich version do you got
and skyfichdo you know why we would upgrade to 2.0 and then back again to 1.5…
clovis:
very sorry that your PSPdowngrading process is failed. Would you mind to share more information about your PSP version and steps which bricked your PSP. Thus, others may aware of this if they have same model as yours.
By the way, you can look for Undiluted Platinum. Please visit link for more information.
demonjay:
Firstly, welcome demonjay to PSP 1.5 world.
For your question, bout after downgraded PSP to 1.50 successfully, it is recommended to upgrade it to 2.0 and back to 1.50.
In my own opinion, It is just extra steps to make sure your downgraded PSP is stable. As it would be able to upgrade to 2.0 and back to PSP 1.50. Just to ensure you obtain clean 1.50 PSP.
koi:
Just plug your PSP to your PC, and run XTRUSION Downgrade file that you have downloaded. It will show you step by steps. Just follow Faisal. It very detail. Good luck dude
ngx:
Congratulation~!, welcome to PSP 1.50 world. hehe
demonjay:
The reason koi need to upgrade to PSP 2.71 because it can be downgrade from 2.71 to 1.50 without using unpatched GTA UMD.
oke koi go for it dude
join us in the wonderfull world of 1.5
and skyfish im going to do more recearch about upgrading 2.0->1.5 again
maybe its best to do this for a cleaner 1.5
but i dont like the second risk:(
i was also wondering wat is the best way to get wallpaper on your 1.5 psp
i dont want to use pspset
is there other way to do this
my friend was 2.0 ‘’still afraid to downgrade” and he just puts his wallpaper files in his psp/photo but with the 1.5 that isnt possible right :O
wher do i find a 1.50 file???
could i find one on the internet
ECHO_FOX:
You can get all required file from the following site, it contains downdater and other required file. Just make sure the one you download is FULL version. good luck dude.

Thanks for all your advice but I still cannot upgrade. I am pc illiterate. I have tried to download onto my psp and my pc but no luck I don’t know what to press, where to save the files and how to access the upgrade, my psp still says 2.6. I have tried copying and pasting onto psp/games file but nothing , when I download what do I press on my psp. I need a step by step guide. Please be as simple as possible. as in go to download save in? put in usb lead?press what button on the psp? What file to save it in?? Help?!!!
Does anyone know if having two codes means that it’s a TA-082???
Check it out. I have two codes on my motherboard!!
IC1003 on the upper right
IC6001 under the UMD case on the left.
WTF
I’ve searched forums and stuff and can’t find anything about the two codes, except me and Ragna (look up).
I don’t want to take a chance and downgrade until I know which board I have … anyone with some wisdom out there?
I want to downgrade my PSP soooooooo bad… But I hella love it… I can’t believe it has a chance to break.
I’d like to know, what are the benefits of having 1.5, and are the instructions the same from a white psp imported from Japan and and American version Black psp?
I also don’t get it. Why is there a 10 percent chance of failing? In what part would it fail? bad manual? made differently?
Is it better to downgrade from 2.6 or from 2.7? I have a 2.6 so i’m wondering.
Nevermind, looking back at what I wrote like an hour ago, I was noob. I’m going to try to downgrade tomorrow. Thanks all. For noobs like me, upgrade to 2.71 and then downgrade. It’s more risky and complicated to do 2.6-1.5 or 2.5-1.5. Good luck for me and everyone else. I’ll tell you guys tomorrow if it worked or not

Sorry guys, I was kinda busy last few days and didn’t respond to you guys.
Anyway, it seems PSP 1.50 members getting more now. ha ha. I should say “Congratulation and welcome to PSP 1.50 world!” to koi, Danny, & demonjay.
koi: sorry bout can’t get back to you earlier to provide detailed information bout downgrading. But it seems you already join PSP 1.50 world now. hope you don’t mind. hehe
Danny: Ha Ha, friend, I can tell from the comments that you really urge to downgrade your PSP badly. Anyway, you decided to take the challenge and now you got what you want. Feel glad of you.
Guys, I have named out the person who successfully downgrade their PSP to 1.50 in the post. Please refer to the post if you would like to know who successfully downgraded their PSP.
However, there are people who did not inform us whether they have successfully downgraded their PSP to 1.50. It will be very appreciated for those who share their downgrading experience and their outcome here.
Hope they are more feedback on this. thanks guys.
hello friend greeting that he has of good for having psp-1007 ver 1.5 you can respond to my mail thanks to me
Hi guys,
ive been reading all of your helpful tips and i think that its great that you’re helping guys like me (know nothing) to downgrade my psp. I have one question, is it easier to downgrade from a 2.5 -1.5 using the full dowgrader from xtrusion or is it easier to upgrade to 2.7 and then downgrade to 1.5. I have the unpatched version of GTA so please any response would be greatly appreciated.
Thanks again
well it worked 100 percent but its a custom devhook firmware if u face issues u need to deo a clean boot i.e update ur psp to 2.0 and run a program called mph downgrader to fool ur psp into thinking its version 1.0 so u can run a 1.5 official sony update file. its highly recommended to do this if ur facing issues like random unstability while running isos
ITS CALLED A CLEAN BOOT GOING FROM 1.5 TO 2.0 BACK TO 1.5, SINCE ITS A OFFICIAL SONY 1.5 UPDATE U HAVE NOTHING TO WORRY WHILE DOING IT AT ALL ITS VERY EASY SUGGEST U TRY IT, SOLVES STABILITY ISSUES ON HOMEBREW, UNLIKE THE 2.7 DOWNGRDED FIRMWARE WHICH HAS BEEN MODIFIED BY DARK ALEX
FAISAL,
I COPIED UR GUIDE AND POSTED IT HERE WITH ALL CREDIT TO U
http://www.hackmypsp.com/forum/viewtopic.php?p=3699#3699
UR GUIDE HAS GOT OVER 7,000 VIEWS
so abishek first of all thats a cool thing you posted faisal guide it would help a lot of people
:) 
and what i wanted ask you was
wat do you recomend…the mph downgrader and then update to a 1.5
or shall i upgrade to a 2.0 and then downgrade to a 1.5
because some peole say that it is best that you peform these steps to get the clean fw
and its better for the long term time
i downgraded from a 2.5 to a 1.5 with the full downgrader from dark_alex and it worked perfectly
Greek Adonis:
Personally, I have no idea which one is better: downgrade from 2.71(without GTA UMD) or from 2.50(with unpatched GTA UMD, eLoader).
I will say both also perform well as long as your PSP is not TA-082 type. So you can just upgrade to 2.71 and downgrade from it
abishek seems have done a very good job by sharing the guide in HACKM
