Hey, a good guide to update the PSP without bricking it and great info. Thanks a bunch and hope to see any further updates for PSP custom firmware.
I have to start at Section C. I downloading cfw 4.01 m33 and 4.01 m33-2. When I go to open it up it gives me all the files. Meaning it doesnt show me a folder name update that I can copy and paste. I thought it was a fluke so I tried downloading the cfw for version 4xx else where they all do the same thing. Help plz!
Thanks so much! I had cfw 5.00m33 for a while but wanted to update to m33-6 but was scared it would brick but it didn’t!
Cheers, this has helped a lot!

I’m very sorry kyo, I have never encountered the bricking problem before and a brief search on the internet seems to indicate that there are PSP slim 2001 owners who managed to upgrade to 5.00 M33-6. Is it possible for you to try to downgrade all the way to 1.5 and start fresh according to this guide?

Gabriel, I’m not sure what you’re trying to say. The whole purpose of the post is for you to upgrade to a newer custom firmware and it will definitely “delete” your former custom firmware.

I just upgrade my firmware form 4.01 m33-2 to 5.00 m33-6, it was a success. But, when I try to play Monster Hunter Freedom Unite and Dissidia, it’s says that my savedata has been corrupted. Can I recover the savedata? Please help me… Thanks
holic, a lot of people have successfully upgraded from 3.90 m33-3 to 5.00 m33-6. Just start from section C.
Ferry, if you look at dReas’s comments (Click on Older Comments), you will see he has the same problem. You can try to use Deemer like I suggested but I’m not sure if it will work.
followed the instructions but when i used 3.52 m33 update it shutdown and now wont restart any ideas please
i followed the steps from 4.01 m33.2 and ended up at 5.00 m33-6 with no issues at all.. im gonna carry on untill i get to whatever the latest firmware is in the hope of curing my game loading errors, but thanks again for getting me this far.
cheers.

Hey
I have a phat PSP using CFW 5.00 M33-6.
I just recently updated it. Now my internet browser wont open and some games are crashing when im playing them. It seems to always crash when something is loading.
Any advice? If not is there a way i can completly Downgrade to OFW 1.50 and start again?
mark m, you can download “(DL.C.6) Custom firmware 5.00 M33-6″ from http://downloads.exophase.com/pub/109
Marty, I’ve got 4 devices with me that is running CFW5.00 M33-6 and we haven’t got any problems. Could it be caused by the ISOs that you are using? Are they directly ripped without any manipulation or compression?
YK: The games were working fine before i updated to M33-6. Now they start but crash during play.
Starting to really fry my head now!
Marty, what version of the CFW were you running before you updated?
Cant remember think it may have been 3.71 m33 or 4.01.
Ive upgradede again to 5.50 GEN- D2 but sits still doing the same thing.
thank u so much!
thanx, i have successfully upgrade my phat. nice guide!
Definitely one of the best guides I have ever used. Thanks for taking the time.
Do you need to use a pandora battery to upgrade from 4.01m33-2 to 5.00m33-6?
JepRox, you don’t need a Pandora’s battery to upgrade from 4.01m33-2 to 5.00m33-6.
Thnx yk, for the reply. Before i upgrade, has anyone tried playing ASSASSINS CREED BLOODLINES for cfw 5.00m33-6? Because for cfw 4.01m33-2 I get an error saying, “The game could not be started.” If cfw 5.00m33-6 gets the same error then whats my other option?
thnx

IM trying to upgrade from 3.71 M33 – 4.01 M33,
