    I have no idea what to do when it says Revert your kernel to 3.52 i got to the recovery menu but i’m confused from there

  6. yk on November 16th, 2009 at 4:35 pm

    Michael,

    For the “Revert your kernel to xxx”, do this:
    (1) Get into recovery menu as described.
    (2) Choose “Configuration”.
    (3) Toggle the “Game folder homebrew (currently at x.xx kernel)” to the version instructed.

  7. Goudy on November 28th, 2009 at 3:51 pm

    Thanks everyone for your help.
    I have a little problem. When I toggle the “game folder homebrew”, it leaves me no choice but to choose the 1.50 kernel.
    I am in 3.71 m33.
    What can i do ?

    help & psp, you open the custom firmware you have download and copy the update file and its content to you (memory stick-psp-game) and then you copy the .PBP file you have download in update folder.
