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
