    Hi All,

    First post so bare with me.

    I was using Custom Firmware 3.40 OE-A successfully on my TA-082 (non slim)PSP but wanted to play the Star Wars Battlefront game which will not work in this firmware apparently. I Managed to downgrade to 1.50 which is my current firmware but have used two different instructions to upgrade to 3.52 M33 which I beleive I have to go to before I got to 3.71. Everything seems to be working until the last step when I get the error message "Writing 3.52 firmware………cannot decrypt reboot.bin" shown below.

    Loading 1.50 firmware………ok
    Writing 1.50 firmware………ok
    Loading 3.52 firmware ……..ok
    Writing 3.52 firmware………cannot decrypt reboot.bin
    Press x to exit

    Any advice would be welcome.

    Cheers

    No luck.

    Same error

    Loading 1.50 firmware………ok
    Writing 1.50 firmware………ok
    Loading 3.52 firmware ……..ok
    Writing 3.52 firmware………cannot decrypt reboot.bin
    Press x to exit

    Is this because its a TA-082 and not a slim version???
