• Sep 4, 2017 - How to Install Custom Firmware (CFW) on PSP 1. 0In this PSP tutorial, you will learn how to install custom firmware of your PSP 1.
• Dec 29, 2017 - All firmware you need here: From 1.50 install 3.52 M33 1 - If you are under official 1.50. 3 - Download official 1.50 eboot, rename it to 150.

For those of you who are new to the concept of hacked PSPs, custom firmware might not sound so familiar. Custom firmware allow you to run homebrew. Homebrew is software developed by the user community.

Enabling this homebrew makes the PSP an open platform. It allows you to add the functions and/or applications that Sony did not take care of.

PSP Firmware 1.50 in PSP Downloads Posted by Evolve on August 6, 2011 Views 35225 Downloads: 5359 0 Comments Official firmware 1.50 update EBOOT for PSP, primarily used as a helper file with HEN, a homebrew enabler capable of downgrading a PSP to 1.50 under the right conditions.

Or better download the complete up-to-date PSP Downgrading/Upgrading Guide now in PDF. Download here. It’s free!

Of course there are two sides to this coin. When you’re dealing with an open platform, piracy arises. Due to this (and probably some other reasons as well), Sony has been trying to repress homebrew as much as possible. Where these apprlications could initially be run on the 1.50 firmware PSPs, users who updated wouldn’t be so fortunate.

But the community (read: hackers) did not accept defeat. Leaks were exploited and one after the other, the firmwares fell. Up to today, neither of the groups have given up, but it is obvious who is winning.

Instead of enabling people to run homebrew, the PSP hacking groups have started building their own PSP custom firmwares. Their firmwares are nearly identical to the official ones, only better. They have all the same functions, but have added functionality and the ability to run homebrew. At some point, people stopped trying to run homebrew on these official firmwares and just developed software to downgrade and/or switch PSP to custom firmware.

There are a lot of different ways to downgrade your PSP, which one you’ll have to use depends on your current firmware. Some are harder to break than other, but it’s always possible.

We will be posting a simple step-by-step guide, so that nearly everyone will be able to find his or her way through the bulk of information available on the web.

LEGAL DISCLAIMER

Using these methods is 100% legal (although Sony obviously doesn’t like it), but it CAN brick your PSP (there is a way to unbrick them, we’ll be discussing that next time). It may also void the warranty of your PSP system as you would be working with delicate parts like the PSP’s flash memory. So if you screw up, Make Use Of won’t be held legally liable. If this sounds like too much risk to you, please don’t go any further.

Part One – Upgrade PSP Firmware 1.00-3.50

Yep, we’ll be starting with firmware versions 1.00 through 3.50. If you have a higher firmware, don’t despair, as we’ll be discussing them in part two (a little more complicated though).

As there’s a lot of different variables and different ways to work with them, we’ll be sending you up and down through this guide to the steps that matter for you. Therefore, for all the speedreaders out there: always read the text in bold red, as it will ‘guide you through this guide’.

Navigation

So we want to install a custom firmware (m33 to be exact). Sadly, we’ll need to have firmware 1.50 to install. If (though this is very unlikely) your PSP is still equiped with FW version 1.00, you’ll have to upgrade to 1.50. To do that, download the update file here and follow the instructions in the file description.

• If you have FW 1.50 or some custom firmware: Go straight to the upgrading guide
• If you have FW 2.00 or below: Go to method a
  
• If you have FW 2.80 or below: Go to method b and c
• If you have FW 3.03 or below: Go to method d
• If you have FW 3.50 or below: Go to method e
• If you have FW 3.51 or higher, check back with us next week

To check which firmware you have, go to Settings -> System Settings -> System Information. Your firmware version will be stated right between your MAC Address and your Nickname.

a) Downgrading PSP from Firmware 2.00 to 1.50

This method uses the tiff exploit. People found out that it was possible to run tiny bits of code through tiff files. In this case, a tiff file is used to change the version number to 1.00, after which you’ll be able to update to 1.50.

Files you need

Please use google if the links are no longer work.

• MPH Downgrader (alternative link here)
• Firmware 1.50 (alternative link here)

Step One: Format your memory stick

This is not always necessary, but it makes the upgrading easier, so be sure to make a back up of all your important files. To do that, Go to Settings -> System Settings -> Format Memory Stickâ„¢ and confirm twice.

Step Two: File Placement

Go to Settings -> USB Connection

Put the EBOOT.PBP file in X:PSPGAMEUPDATE (where X: is your PSP) and extract the MPH Downgrader zip in your PSP root (main folder). If you are prompted about replacing any files, click ‘Yes to All’.

Step Three: Downgrading

Go to Photo -> Memory Stickâ„¢. You’ll see a black screen with some numbers. Don’t be afraid, this is just the program doing its work.

Wait about 30 seconds and restart your PSP (hold your power switch up until it switches off and turn it back on).

Now, go to Game -> Memory Stickâ„¢ and open ‘PSPâ„¢ Update ver 1.50’

You’ll see an error at the end of the update. Don’t be nervous, this is perfectly normal. Restart the PSP manually. You’ll then encounter another error, press O to restart.

Congratulations, you’ve now got Firmware 1.50, move on to the upgrading guide.

b) Downgrading PSP from firmware 2.80 to 1.50

First of all, if you have a lower firmware version, you’ll have to upgrade to 2.80.

Download this file and put it in X:PSPGAMEUPDATE (with X: being your PSP). Then go to Game -> Memory Stickâ„¢ and open ‘PSPâ„¢ Update ver 2.80’.

This method also uses the tiff exploit, which enables small pieces of code to be run through tiff files.

If this method does not work for you, check below for an alternative updating way.

Files you need:

Please use google if the links are no longer work.

• HEN for Firmware 2.80 (alternative link here [No Longer Available])
• v2.80 Downgrader [No Longer Available]
• Firmware 1.50 (alternative link here)

Step One: Format your memory stick

This is not always necessary, but it makes the upgrading easier, so be sure to make a back up of all your important files. Go to Settings -> System Settings -> Format Memory Stickâ„¢ and confirm twice.

Step Two: File Placement

UnRAR the HEN archive. Move the contents from the MS_ROOT folder to your PSPs root (this is the main folder).

Also move the contents of the ta82downgrader.zip MS_ROOT folder to your PSP’s root. Rename the FW 1.50 EBOOT.PBP file to UPDATE.PBP and move it to X:PSPGAMEUPDATE (with X: being your psp).

Step Three: Downgrading

First of all, we’re going to activate HEN (Homebrew ENabler). After that, we browse to the Photo menu and try to open the HEN_280 folder. If the PSP just freezes, reboot and try again. At some point the screen will flash in a specific color.

• – If red, the program ran, but if it failed, you’ll have to try again.

– If blue, the program succeeded and is running. Your PSP will automatically reboot.

Next we’re going to run the downgrader. To do this, go to Game -> Memory Stickâ„¢ and open the PSPâ„¢ Update ver X.YZ (you’ll need at least 75% battery for this).

At the end of the installation, you’ll be prompted to press X, after which your PSP will restart. Enjoy, you’ve now got Firmware 1.50!

Move on to the upgrading guide.

c) Downgrading PSP from Firmware 2.80 to 1.50 (alternative way)

First of all, if you have a lower firmware version, you’ll have to upgrade to 2.80.

Download this file and put it in X:PSPGAMEUPDATE (with X: being your PSP). Then go to Game -> Memory Stickâ„¢ and open ‘PSPâ„¢ Update ver 2.80’.

Files you need:

Please use google if the links are no longer work.

• 2.80 Easy Downdater (alternative link here)
• eLoader/xLoader (alternative link here [No Longer Available])
• PatchSFO (alternative link here [No Longer Available])
• Firmware 1.50 (alternative link here)

Step One: Make sure you don’t have a TA-082 motherboard

If you use this updating technique with a TA-082 PSP you’ll be left with a shiny brick.

If you DO have a TA-082 PSP, check above for another updating way.

Step Two: Format your memory stick

This is not always necessary, but it makes the upgrading easier, so be sure to make a back up of all your important files. Go to Settings -> System Settings -> Format Memory Stickâ„¢ and confirm twice.

Step Three: File placement

Go to Settings -> USB Connection. Open the eLoader installation file. It will try to automatically connect to your PSP. If it fails to do so, just select the PSP root (main folder) manually. You can leave all the other settings alone.

Unzip the PatchSFO EBOOT to X:PSPGAMEPatchSFO and the FW 1.50 EBOOT.PBP file to X:PSPGAMEUPDATE (where X: is your PSP).

Open the 2.80 Easy Downdater installation file and select your PSP’s root. Press next to install the files.

Step Four: Downgrading

First we’re going to need to patch the files with eLoader. To do so, go to Photo -> Memory Stickâ„¢, and hold the start button while hovering over the eLoader folder. There’s a possibility that your PSP crashes. If so, just do a hard reboot by holding the power switch and try again.

Once inside the eLoader application, open PatchSFO and press on X to confirm. PatchSFO will now patch all files. This means we can open Easy Downgrader through xLoader in a moment. Do not try to open the installer with eLoader, as eLoader and xLoader are two totally different applications. Opening Easy Downgrader with eLoader might even brick your PSP

Once PatchSFO is done, press start to reboot your PSP.

Now we’re going to open xLoader. Again, hold start for a few seconds when hovering over the xLoader folder. If your PSP crashes, do a hard reboot and try again. At one moment, you’ll get an error message as shown below. This means xLoader has successfully started. You’ll also be able to view the files contained within the folder now.

Now we can start the updater. Go to Game -> Memory Stickâ„¢ and open the installer (1.50DDforTA-079~081FW2.80PSP). Press O to start the installation.

At the end of the update you’ll see an error. Don’t be nervous, this is perfectly normal. Restart the PSP by pressing O.

Congratulations, you’ve now got Firmware 1.50, move on to the upgrading guide.

d) Downgrading PSP from firmware 3.03 to 1.50

First of all, if you have a lower firmware version, you’ll have to upgrade to 3.03.

Download this file [No Longer Available], rename it to EBOOT.PBP and put it in X:PSPGAMEUPDATE (with X: being your PSP). Then go to Game -> Memory Stickâ„¢ and open ‘PSPâ„¢ Update ver 3.03’.

You’ll need an unpatched copy of GTA:LCS for this method. This means that it contains a version 2.00 Firware update file. Though this might strike you as odd at first, it’s genius when you know the details.

When Sony closed the tiff-gate, the hackers went looking for other glitches in the PSP firmware. At first they couldn’t find any, but then they made a very unexpected move. They used a glitch in GTA:LCS, a game for the PSP! Now, they could load nearly any piece of code using savefiles. Sony didn’t like this though, so they made sure this wasn’t possible with all next releases and/or firmwares.

I only suggest this method if you actually own this game, don’t go running to the store to get a copy. Next time we’ll talk about a way to downgrade and unbrick each and every PSP (you need another PSP for it, though).

Check this article to see if your game is patched or not, or just insert it in your PSP and look what Firmware version it contains (2.00 is an unpatched one). Check this as well.

If you haven’t got a copy of GTA:LCS in your possesion, but you do have a copy of Lumines, skip down to method d below.

Files you need:

Please use google if the links are no longer work.

• An unpatched copy of GTA:LCS
• 3.03 Downgrader (alternative link here [No Longer Available])
• Firmware 1.50 (alternative link here)

For installation, read steps one to three of method e.

e) Downgrading from firmware 3.50 to 1.50

First of all, if you have a lower firmware version, you’ll have to upgrade to 3.50.

Download this file and put it in X:PSPGAMEUPDATE (with X: being your PSP). Then go to Game -> Memory Stickâ„¢ and open ‘PSPâ„¢ Update ver 3.50’.

A little déjà vu here, the hacker community did it again! Instead of using Liberty City (more details above), they used a save-game exploit and a copy of the nifty puzzle game Lumines to get in. Note that the installation is also very similar to the GTA version.

Files you need:

(use google if the below links are offline)

Ps1 Eboot Download

• An unpatched copy of Lumines
• Universal 3.50 HEN/Downgrader (alternative link here [No Longer Available])
• Firmware 1.50 (alternative link here)

Step One: Format your memory stick

This is not always necessary, but it makes the upgrading easier, so be sure to make a back up of all your important files. Go to Settings -> System Settings -> Format Memory Stickâ„¢ and confirm twice.

Step Two: File placement

UnRAR the downgrader and move all the files from the MS_ROOT folder in the root (main folder) of your PSP. If you are prompted about replacing any files, click ‘Yes to All’.

Rename the version 1.50 Firmware file from to UPDATE.PBP and drop it in X:PSPGAMEUPDATE (with X: being your PSP). Be sure not to overwrite EBOOT.PBP in the UPDATE folder!

Step Three: Downgrading

Start the game. As soon as it starts loading the savefile the screen will turn black and restart. Normally, you are now running HEN (Homebrew Enabler) which allows you to run homebrew files.

To check, go to System -> System Settings -> System information and look at your system version. It should state ‘303 HEN’. If not, start over.

You can now start to downgrade. Go to Game -> Memory Stickâ„¢ and open the PSPâ„¢ Update ver X.YZ

If you have an unpatched TA-082 of TA-086 motherboard, you’ll be asked if you want to patch it. You can only proceed with the installation if you do. Next, you’ll encounter one last confirmation screen, press X to continue.

Once the installation is complete, you can press X to restart your system. Congratulations, you know have a PSP with firmware 1.50!

If you get an error saying that the ‘settings are corrupt’, you’ll have to restore your pre-installation network settings manually by going to Game -> Memory Stickâ„¢ and starting the NetConfigBackup utility and selecting restore.

Move on tothe upgrading guide.

Upgrading your PSP to a custom firmware

Now you’re in Firmware 1.50, we can upgrade to a custom firmware. The big advantage is that we’ll have all the advantages of the higher firmwares in combination with the ability to run homebrew.

Things we need:

• Custom Firmware 3.52 M33 (alternative link here)
• Custom Firmware 3.52 M33-3 [No Longer Available]
• The latest M33 Firmware version [No Longer Available] (5.00-3 at the time of writing)
• The parallel official fimware (5.00 in this case – mirror)
• Firmware 3.51 (alternative link here)
• Firmware 1.50 (alternative link here)

Step One: Format your memory stick

This is not always necessary, but it makes the upgrading easier, so be sure to make a back up of all your important files. Besides, you’ve probably got a lot of unnecessary junk on there from the downgrading process.

Go to Settings -> System Settings -> Format Memory Stickâ„¢ and confirm twice.

Step Two: Upgrade to Custom Firmware 3.52 M33

Before we can upgrade to the latest version of the M33 firmware, we must first do an initial upgrade to one of the first M33 versions, CFW 3.52.

a) File placement

1.50 Eboot Download

First of all, unRAR all the downloaded files.

If you are on FW 1.50, copy ‘kxploitpatcher and kxploitpatcher%’ to the directory X:/PSP/GAME (where X: is your PSP). If you are on another custom firmware, skip this step.

Copy the M33CREATOR folder from the 3.52 M33 rar to X:/PSP/GAME (where X: is your PSP). Rename the 1.50 and 3.52 EBOOT files respectively 150.PBP and 352.PBP and move them to the M33CREATOR as well.

b) Updating

If you are on FW 1.50 go to Game -> Memory Stickâ„¢ and open KXploit Permanent Patcher. This will permanently allow non-patched eboots to load. When prompted, press X. Your PSP will restart automatically when done. If you are on another custom firmware, skip this step.

Next, start 3.51 M33 CREATOR, also in the Game’s Memory Stickâ„¢ menu. After it has loaded and rewritten the firmwares (this can take a while), you can press X to restart.

M33 CREATOR has now built an update file. Once again, go to Game -> Memory Stickâ„¢ and open 3.52 M33UPDATE. You need to have at least 75% battery left to do this. You’ll be asked for confirmation. Press X to continue or R to exit.

Press X at the end of the installation to turn your PSP off, turn it back on manually. Congratulations, you are now on 3.52 M33!

Let’s get rid of all those unnecessary files. Format your memory stick again as explained above.

Step Three: Update to 3.52 M33-3

Unrar the 3.52 M33-3 files. Drop the PSP folder in your PSPs root (main folder).

Go to Game -> Memory Stickâ„¢ and open the nameless utility. You’ll get a nice read about a website they don’t seem to like. Press X to do the update, this one will go real quick.

Step Three: Upgrade to the latest Custom Firmware

a) File placement

If you haven’t extracted the downloaded firmware yet (we’re going to use 5.00 M33-3), do it now.

Move the unRARred UPDATE folder to X:PSPGAMEUPDATE (with X: being your PSP). Also add the parallel official firmware to that folder, renamed in the same manner as in 2.a

b) Updating

Go to Game -> Memory Stickâ„¢ and open the installation file. After verifying the eboot, it’ll ask you for confirmation. Press X to continue.

Follow the on-screen instructions to update. The update will take five minutes or less.

Congratulations, you are now on the latest M33 custom firmware!

It’s no more than fair to say a brief thank you to Dark_Alex, for everything he has done on the scene. The guy’s a legend, and he deserves it.

65. can u tell me plyzz how to downgrade psp 1006k model to1.05 or any version that can play games on mem card plyzzz i need it urgent.

66. Hi, I have just bought a PSP 2006 slim and i believe that it had a OFW of 5.03 but my bad that i have upgraded my OFW to 6.00. Techies here told me that i won't be able to go back to my OFW and that 6.00 is not hackable. Is this true? Right now, i can only play with UMDs and Trial games i put in my Mem card. Are there full games that i can play thru mem card? Is there a way that i can get back to my OFW so I can have it hacked with -33M?
    Please help...
    I appreciate so much for any help you can extend.
    Thank you.

    • Jet well who ever told you that 6.00 cant be hacked they are up them self's you can down grade from it either use hell cats recovery flasher 1.50 or you tube it and something will come up but you all so will need a Pandora battery for slim or lite what ever one you have you can buy them off dealextreme they are a American seller that's where i got mine even tho i`m from Australia if you have any questions just reply and i`ll respond as fast as i can.

67. well i herd FIFA 10 should work did you put the beta update on it and if you havent update it if you have then i`m not really sure then aftab you probly have to wait till the next custom firmware comes out if it does or you can find a patched version of FIFA 10 or something

68. my psp was updated to 5.0 but i cant seem to play any of the newer games whether downloaded or original umd's (i have both versions for Fifa 10 and both dont work)...plz help me out

    • well hate to say this is upgrade your CFW =Custom Firmware to 5.50MHU beta 2 then FIFA should work but any newer game needs higher then that to find out what version the games are from your UMD plug your usb connection from your psp into PC while using the UMD as the storage method then download UMDGen there will be a window with it on as details and it should say something about UMD version like for examples Final Fantasy Dissida is firmware 5.55 it will state 5.55 and if you have the ISO on the PC already or on your psp just download UMDGen and find the file.

      • ok so i upgraded to 5.50 from 5.0 using the fifa 10 umd and now its not reading the games on my mem card..is there a way that both types of new games (umd and pirated) can work together??

69. please help me!!!im update the latest version of fimware...6.10...i want to downgrade it..so i can play pirated games..after im upgrading to version 6.10..all my games become corrupted!!so please help me!!im using fat psp ....1000..

    • well you need a Pandora`s battery first then you need the program hellcats recovery flasher 1.50 that will down/up grade your psp and fix semi-bricked psp's like your one Sofrie and the reason they have gone corrupted is because it isn't a custom firmware CFW the highest one you can get at the moment is 5.50MHU-2(that's what i got) it can play some new games that have been released but not all because of their firmware needing 5.55 and CFW hasn't brang out that yet.

      • ...actually i dont know anything about how to downgrade this one..is there any tutorial for downgrading this 6.10 version??thanks..

      • thanks for the answer..i try to follow what have u said!!!thanks again!!

      • i try what u have told me..but it wont work..it said the data corrupted..what should i do now??please help me...im lost rite now...

        • what version are you at on your psp um and what game are you trying to run?

70. mine is 2006 i can play iso games before i update it to 6.0 and now that i updated it no more games for me T_T any links where can i download it.
    tnx a lot

    • okay your psp sounds like its semi bricked buy a pandora's battery and just google hellcats recovery flasher 1.60

71. sir how can i downgrade a psp 200X with a version of 6.0?? pls reply tnx a lot

    • I fixed mine it was semi-bricked i put on hellcat's recovery flasher 1.60v it only works if you had your psp modded with cfw then all you have to do is run it from the game section on your psp menu and it will come up on a menu and then you can downgrade to the latest 5.00m33 or upgrade to the latest 5.50MHU-2 i hope this works for you Rhen

      • but you allso need a pandora's battery to beable to unbrick

72. Hi Simon,

     Thanks and more power.

     P.S. READERS: Before you readers impulsively go out and buy a PSP to hack it, stop... look at all of Gamestop or whatever's used PSPs and find the lowest version OR go on eBay and search 'PSP 1.50' I got a 1.50 off eBay for just $80 :) Good luck.

     The games are in .pbp format.

     • popsloader is an program that let you use lower firmwares but not changing your firmware. this let you play ps1 games that cannot be play by your current firmware.

       you can play ps1 game even you don't have popsloader. but there are games that needs popsloader. try to look on compatibility test in psx game, that needed popsloader. you cannot play ps2 games on psp.

182. According to your guide 'Upgrading your PSP to a custom firmware', we need Custom Firmware 3.52 M33 and firmware 3.51.
     Why firmware 3.51 and not 3.52 ? Besides that, According to your guide, we rename 3.52 BOOT to 352.PBP, in spite of we have downloaded 3.51 BOOT. Would you please explain to me what's the right firmware, 3.51 or 3.52 ?

183. How to downgrade or even shift over to a cfw from ofw 5.02. I forgot about the hacking scene when I sold my last psp back in 04. Now I got a slim and upgraded without even thinking. I miss my homebrew even more now. My sidekick sucks.

184. i just got my psp and its 3000 with a 5.02 and i have a mac computer and i was wondering how i can hack it , many thanks.

     • FOR THE LAST TIME YOU CANNOT HACK THE PSP 3000...................................YET

     thank yoy

187. One quick note. Shouldn't you link to firmware 3.52 since that's the update that's being done? I don't understand why you put a link to 3.51 or why you said '3.51 M33 Creator' instead of 3.52 M33 creator. Other than that, it worked like a charm! Thanks a lot!

     • I second Doug's comment. Was a bit confused with the 3.52 on the guide and the 3.51 link (and file in the screenshot) but after using the right one it worked like a charm indeed. Had never had a PSP in my hands before, got a 1003 with FW 2.60 today and within minutes it was cracked to 5.00 M33!

       Thanks a lot!

188. first off, good guide. looks well thought out and well researched.

     my only question is if there is ANY way, at all, to downgrade, crack, or just ultimately get an M33 firmware on my Official 5.02 Firmware PSP? is there ANY way???

     thanx in advance. good work. :)

189. Hi Simon:

     This (and part 1) are the best guides I've seen on the net. I'm a nooby, just bought a 3000, and upgraded it to 5.02 b4 knowing about CFWs/homebrews/etc (I was way bummed when I did!!). I understand the 3000 is not hackable at this time, so how can I know when a new procedure is published?

     Thanks again for your time and efforts!

     Regards,

     ELenk

199. I have version 1.51 on a psp 1001, i was going to start at method A and downgrade to 1.50 and the screen did not turn black when i went to photo/memory stick, The option to update to version 1.50 is in the game folder when i navigate to it in the psp,i followed the file placement instructions exactly twice and have the same result both times, do i go straight to upgrading to custom, do i need to upgrade to 2.8 then downgrade to 1.50 or is there another step i need to complete first, also i apologize for my lack of knowlege on this subject, and thank you for any help you can offer

200. does this work for fat psps? like the ones when they first released the first psp? cuz im thinking of buying one but if i cant mod it then i might as well not try in risk of damaging it

201. can I hard/soft mod this battery : sony 3.6v 1200mAh ? plz I need the answer !

202. where do I get the lumines patch

203. First off.. it would be a good idea to downgrade your PSP to 1.50 before you try to install a new custom firmware to it. Second, If you go to part 2 of this guide, there are 3 methods in which you can downgrade ANY official firmware on a PSP 1000 and 2000 (it cannot be done with the new PSP 3000). the 3 methods are: 1.) If you have a spare battery, it gives you a link on how to make a pandora battery; 1.) if you have a friend with another custom firmware psp, you will be able to downgrade thanks to him/her; 3.) or if u have niether... it will tell you to buy 1 (it's very cheap if you look in the right place: dealextreme.com/details.dx/sku.15153 <-- this is the one i got =P) and tell you how to downgrade it from there. It's a very good guide.

204. i am new to this custom firmware thing can somebody help me.... do i need to downgrade to firmware 1.50 to get custom firmware? or do i just start downloading custom firmware....
     none of the articles work for me because i have firmware 3.73 and no extra battery to make pandoas

205. One more victim of upgrading psp to v5.1 can any one sort it out and help me dongrade. can u plizz sugest which version is the better one>??

206. i need help. i just update my psp to official 5.01 firmware because i think it ok. but now i need to downgrade it back and i need it fast!! can some one in this big world tell me the method or something that i can do to make these thing to downgrade it back to some custom firmware? it it because my PSP can't play a game that i saved in my Memory Stick!!!! SHIT SONY!!!!!!!!!!!

207. can you post how to downgrade your psp to ant custom firmware or official from official firmware 5.01?
     please can you post that i really need it

     • I, too, have official firmware 5.01. I believe that in order to downgrade your PSP from this firmware is in part 2:

       Copy this link to your browser, and find the option that is right for you.

208. When are they gonna put how to get it for users with 3.51 and up??? i have 5.02 sooo im waiting lol

209. can i use the demo disc vol 1 to downgrade a 3.03 psp it has the 2.00 update on it many thanks

210. hi there..can you help me out here?..i have read your toturial but still i dont get it..i have a psp model 1006..and i have updated my psp version to official firmware 5.01...and what's the step i should follow to upgrade to a custom firmware..please tell me and guild me thank you..

211. You don't have to have a custom firmware PSP, I made my Pandora's battery by a battery hardware mod. (Search it on Google)

212. And don't forget the new PSP-3000. Nothing works for it for the time being.

     • lol. noobs. for psp-2000 to get custom firmware without using a pandora battery is to update to 5.03 offical firmware then use chickhen r2 then use hellcat's recovery flasher to flash m33 to ur psp. for psp-3000 same thing as for psp-2000 except you can't flash m33 on it. u can use custom firmware enabler to mimic m33 until u completely shutdown the psp. if u do then just do the steps again. btw chickhen enables homebrew to be run but just homebrew. it doesn't touch the flash of the psp so if u completely shutdown the psp then u gotta do the steps again

213. This is only applicable for PSP Phat models. You need to use Pandora for PSP Slim (PSP-2000) and in order to make your own pandora, you need a PSP with custom firmware. cheers

214. The Easiest way to do this is by using pandora's battery!! Maybe you should make a tutorial about how to do that? Also maybe add CXMB that's custom themes for the PSP.

     • DOES ANYONE KNOW HOW TO DOWNGRADE FROM THa ofw 6.20???? my nephew did the upgrade and now its saying my files are corrupt when i try to play my emulators
