Upgarde to 3.95

Hey there.
Before updating to 5.50 Gen-D3 (which is a higher version than yours), try knowing your PSP MoBo first. Why? Because, you may brick your PSP with the upgrade. Use PSPident to do that. Here's a link for that (MONSTER here!!!). Don't mind the monster, I just thought it's kinda nice doin' that. LOL
Now, do that PSPident in your PSP. If your MoBo appear to be TA088v3, DO NOT (never ever) upgrade to 5.50 Gen-D3 or you will have your PSP dead... If your MoBo is LOWER than TA088v3 (like, say, TA085v1 or v2) then go on with the 5.50 Gen-D3.
If upgrading doesn't solve your problem with playing homebrew, you may have downloaded a corrupted ISO or CSO file... Find a new torrent for that game again...
Happy playing...

If you had custom firmware on your PSP, and upgraded to 6.37, there is currently no way to downgrade to the old CFW or to play any downloaded ISO files. You will need to wait until a new custom firmware is release or a down grade patch is available.

the file is wrong , you should download the file again

you need to download game that are compatiple with v5.51

the PSP has to be hacked in order for you to play downloaded games. If you get a magic memory stick and a pandora battery it can be done easily even with the 5.50 firmware version. Google pandora battery, and magic memory stic or (psp mmj tutorial) and you get lots of good info.

Hope this helps.

download custom firmware. It should fix it. email me at [email protected]

IF YOU WANT TO THE OLD VERSION BACK AND PLAY AGAIN...... HOLD THE SWITCH UPWARD AT THE SAME TIME HOLD THE L AND R BUTTON AFTER THAT THE M33 RECOVERY MENU APPEAR... IF YOU HAVE SOME QUESTION JUST EMAIL AT [email protected]

hi your previous psp version is 3.80 m33 if yes your using custom firmware that why you can play game to your memory stick the problem is you upgrade your psp firmware to sony official firmware 5.01 you reinstall your firwmware again using custom firmware like 5.00 m33-3 cfw below with m33 or OE

because you upgrade the system of your psp to a sony official firmware that why you cannot play your games to your memory card you need mod your psp using magic memorystick, pandora battery and custom firmware so that can install custom firmware to psp.

check yur version maybe u nid the latest updates 3.8 or 3.9
