    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?

  13. yk on September 23rd, 2009 at 3:45 pm

    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.

  14. Jon on September 28th, 2009 at 8:09 am

  20. Ferry on October 11th, 2009 at 6:25 pm

    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

  21. yk on October 12th, 2009 at 12:06 am

    holic, a lot of people have successfully upgraded from 3.90 m33-3 to 5.00 m33-6. Just start from section C.

  22. yk on October 12th, 2009 at 12:08 am

    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.

  23. neil on October 21st, 2009 at 5:13 am

    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.

  25. mark m on October 31st, 2009 at 9:52 am

    can you upload “(DL.C.6) Custom firmware 5.00 M33-6″ again?…

    thanks alot!

  26. Marty on November 4th, 2009 at 3:03 am

    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?

  27. yk on November 9th, 2009 at 7:17 pm

    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?

  28. Marty on November 11th, 2009 at 12:59 am

    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!

  29. yk on November 11th, 2009 at 7:38 am

    Marty, what version of the CFW were you running before you updated?

  30. Marty on November 11th, 2009 at 4:54 pm

    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.

  31. Eric on November 20th, 2009 at 1:42 pm

  34. JepRox on December 2nd, 2009 at 10:53 am

    Do you need to use a pandora battery to upgrade from 4.01m33-2 to 5.00m33-6?

  35. yk on December 3rd, 2009 at 10:35 am

    JepRox, you don’t need a Pandora’s battery to upgrade from 4.01m33-2 to 5.00m33-6.

  36. JepRox on December 4th, 2009 at 11:11 am

    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

  43. Gene on February 12th, 2010 at 3:00 pm

    IM trying to upgrade from 3.71 M33 – 4.01 M33,

    I followed section 3 and got up to opening the upgrade file on my psp, but then the screen goes black and white fonts saying “Verifying 401.PBP … File Incorrect”

    So what do i do now?

  44. yk on February 13th, 2010 at 2:08 pm

    Hi Gene, that error message usually means that you have got the wrong version of the Official Firmware. Please download the OFW 4.01 and renamed it to 401.PBP and try again.
