Hello there

Download MPH Downgrader and Firmware version you want(e.g 1.50) to the Windows-based computer. Connect the PSP Slim to the computer's USB port using the USB connector. Transfer the two programs to the main folder of the PSP Slim. Disconnect the PSP Slim from the computer's USB hub when the transfer is complete.

Turn on the PSP Slim. Go to the Settings/USB Connection in the Home menu and select the EBOOT.PBP file in the PSP\GAME\UPDATE update folder. Extract the MPH Downgrader zip file to the root folder of the PSP. Click OK using the X button if you are prompted that this will replace some files.

Go to Photo/Memory Stick in the Home menu. Wait as the screen goes black and numbers appear. Wait two minutes and then press and hold the power switch until the PSP Slim turns off. Release the power switch.

Wait as the PSP Slim turns on and reboots. Go to Game/Memory Stick in the Home menu and select PSPS Update version 1.50. Press the X button to start the update.

Wait as the update finishes and presents an error message. Press the O button to restart the PSP.

If you have a PSP-3000 series, this is currently impossible

If you have a PSP-2000 series without the TA-088 motherboard, then download a downgrader

If your PSP is hacked, its easy: creat on the root of your Memory Stick a folder named ISO, and just drag and drop .iso files in it, you should access them by the memory stick menu under Games in your XMB. If your PSP isnt hacked yet, maybe visit PSP-HACKS.com or PSPGEN.com (English: PSPhacks and PSPGen french but french one is best.)

you need x and triangle also to put custom firmware on first if it is a fat psp check to make sure you dont have a ta-082 motherboard otherwise if you do have a ta-082 or a slim psp you need to do a pandora battery downgrade

currently there is not a 5.51 to 4.00 downgrader. please check on the bottom of the silver trim on your psp there should be a bar code if the first four digits are AB02 then the psp is unhackable and you will have to use HEN to play games if the 4 digits are AB01 and below you can hack the psp via pandora

You have a ta-082 and can't go above 3.11
you need to downgrade to the origional firmware

you will find what you need here.

it's not out yet everyones been looking for one since january sorry man you just have to wait with the rest of us. I last updated my psp in january and got 3.40 and that sucks since i had 3.00 before it. Maybe in a year it'll be released but until then don't upgrade

fact: it is illegal to download those games fact: it is possible to brick ur psp in the process fact: to do it go to a hack site download the downgrader (i dont hink ther is one for 3.5 tho) then run it on ur psp opinion: dont do its too risky hoped this helped :)

You should be able to downgrade with GTA. You might want to try it again with a different downgrader. I would recommend following this guide to downgrade http://boardsus.playstation.com/playstation/board/message?board.id=psp&thread.id=2792391 Then install this custom firmware so all the retail games will work as well as any homebrew application you might want to run. http://www.evilpsp.com/Custom+PSP+Firmware+3.3+0+by+Dark+Alex+PSP
