If the icon says M33 then yeah it will work.

Read one of the guides, You will need a pandora and more than likely DC7

A little research goes a long way.

Hi,

I just bought my PSP (Slim).
I am running 3.71 M33-2 but was not able to run any .cso or .iso games on memory stick eventhough the games i downloaded were stated to be tested to work with 3.71 M33-2. So decide to upgrade it and found this thread.
From the guide I should be able to upgrade to 4.01 M33-2 without any issue, however i am encountering a problem.

I followed the instruction by downloading all 3 files (4.01 M33, 4.01 PBP and 4.01 M33-2)
I extracted all files, copy the UPDATE folder from 4.01 M33 along with 4.01 PBP in it into my PSP \PSP\GAME folder.
Then i run the 4.01 upgrade on my games menu. It shows unpacking...ok, please wait... then my PSP just turned off itself. I reboot my PSP, USB connected it and found that the files had actually been unpacked, I then try to run the upgrade again, this time it shows unpacking...ok, please wait... and my screen turns black and hangs.
I reboot again and rerun the upgrade, this time it shows unpacking...ok, please wait..., verifying 4.01 PBP...incorrect file and auto reboot my PSP.

I tried reformatting my memory stick and also redownload all the files, redo all the steps from the guide, still stuck at where i am now.

Kindly help as my 3.71 M33-2 does not seems to be able to play any .cso and .iso games i downloaded so far (all gives me the game unable to start... error)

Thanks in advance.

at first, don't try to write about downloaded games and anything that is illegal, you might face a ban! check here

i think you changed the UMD ISO Mode in VSH menu, goto your VSH menu(by pressing start or select in XMB) and change umd iso mode to m33 driver, it may fix your problem about running games.

i have the same problem you have in updating a psp to 4.01M33 , i recommend to use a pandora battery. check this thread

Because dark alex site is down/offline, just wondering if you got a mirrored copy of the 1.50 addon patch for 4.01M33-2?

I know Dark Alex has been releasing 1.50 addon patches seperate to the main CFW M33 releases, and he has a different 1.50 addon version that corresponds to each new CFW release.

The last I got was 1.50 addon for 3.90M33-3
