PSP Official Firmware 5.02


I upgraded my PSP to OFW 5.02 and it seems I can't play my games saved on my memory stick duo...

I'm new to upgrading firmware and I never knew that there's a custom firmware..

what's the difference between Custom Firmware and Official Firmware??

can i possibly upgrade to Custom Firmware 5.02 M33(if there's any) from my Official Firmware 5.02??

coz I want to play my games...

hoping for someone who could answer my problem... thanks..

Dude this is so simple trust me I am also a newbie to the whole cfw thing.
now all you need to do is download the cfw from www.pspslimhacks.com or dashhacks or even google pro cfw psp.but pro cfw is kinda the best cauz it gives you a step by step instalation .also if you want you can get 5.50 gen-d or something you can go to system update on psp and update to 5.50.then google 5.50 gen d.
ofw cant play iso or cso my suggestion get cfw.you can get free games and emulaters!!![apps]

SOURCE: can i install on official firmware custom firmware

honestly, you might have screwed yourself over w/ that update. the reason sony updates their firmware is to try to lock hackers out of modding their device. i'm really not sure how long 4.1 has been out or whether it's been hacked or not (i stopped keeping up w/ that since i last updated my custom fw to 3 point 8 or 9, i forgot...). you'll have to check w/ a liable source such as psp.qj.net to see if it has been hacked or not. also there is some new unbricking/downgrading battery called the pandora battery or something like that. i downgraded way before that came out, so i really now nothing about, although i can tell you that it is confirmed that they do work, but beware of fakes, especially on ebay

SOURCE: XiaoFeiChong's Custom Firmware 5.02

If you want to upgrade, you must downgrade first. Any custom firmware upgrade cannot take place unless your PSP is firmware 1.5 or lower.

Chances are that you have a different firmware. If you want to get a custom firmware and downgrade, it is a very complex process that I do NOT recommend if you do not know what you are doing. It is very easy to ruin your PSP during the process. If you are still interested, research "Pandora's Battery" and other downgraders. It is a very long process too long to be explained here, and there are many guides online.

If you miraculously have a PSP that is firmware 1.5, I recommend getting firmware 5.00 m33-4 instead, as it is much more stable. Don't attempt anything unless you understand the consequences of possibly ruining your PSP.

Sorry if I scared you...

Why is my psp not recognize the games after upgrade my psp to 6.00


Because you are using an Official Firmware(OFW) try
downgrading to a 5.00M33-6 Custom firmware(CFW)
you can easily do this with a pandora battery which will install 5.00 OFW on your psp and then you simply download the 5.00m33-6 CFW update
OR
download
1. Hellcat's Recovery Flasher
2. 5.00 OFW it is 25.83MB

install the Hellcat's Recovery Flasher on the psp
and put the 5.00 OFW on the psp
This files should be put in this directory
PSP/GAME

open the Hellcat's Recovery Flasher in the memory- stick of the Game section when the psp is on

follow the instructions
ENJOY..!!

I upgraded my psp 2006 from 5.00 m33-6 to version 5.50. Now it does not detect the games saved in my memory stick. What should i do?


Are you trying to play the game from the memory stick? Or are you trying to play a game from the UMD and retrieve the saved game data from the memory stick?

5.00 m33 is a custom firmware that allows the PSP to play games stored on a memory stick. If you upgrade to 5.50, which is an original Sony firmware, that functionality will go away. If you have custom firmware, you should never upgrade it or the features like playing homebrew or loading games from a memory stick will go away.

You need Custom Firmware to play downloaded games, unless you own them its illegal. Google: "Pandoras Battery"

Thats what you need to install Custom Firmware.

I upgrade my psp in version 5.01, now i cant play my games


HELLO! There's no need to downgrade ur PSP. If u have upgraded ur PSP from the official site and a official firmware has been installed on to ur PSP, it won't execute games(ISO,CSO) from ur memory stick. It will only run games from the UMD. If u want to run ur games from a memory stick u have to install a CUSTOM FIRMWARE. Try www.psp-hacks.com these guys have many softwares on their site. Dont worry its not that hard to put a Custom firmware onto ur PSP.

I upgrade to v5.02 and now my psp wont recognize any games


Be sure that you have your games saved in a folder named - ISO. You also need to have a CFW or homebrew enabled PSP. If you upgraded to official firmware than your PSP won't be able to use the game files.

Games not showing


Sounds like you had homebrew or similar firmware to play images (copied games) from your memory stick. Now that you have upgraded your firmware to an official Sony release these are no longer supported.
