Ok, so I had been running 3.40 OE-A for a long while with no real reason to upgrade. Finally got a game that needs a higher firmware.
So I followed the advice of several people on here and set about getting up to 3.90 M33, starting with 3.52 M33.
I have succesfully installed up to 3.52 M33-4 but when i run the 3.90 M33 update from the XMB it seems to hang.
All I get on screen is:
and then it doesnt do anything else. I have followed the steps provided in the sticky guide http://forums.qj.net/f-psp-firmware-...on-134053.html but it just doesnt want to get past this point.
Any help would be greatly appreciated.
