Can I use Minimus AVR (ATMEL AT90USB162) with downgrade HEX for FW 3.72
I have a Minimus AVR (ATMEL AT90USB162). Unfortunately a friend has received a PS3 Slim 250GB with firmware 3.72 on it.
Can i use any payload (HEX) on this USB key to be able to downgrade the PS3 as mentioned in the threads on PSHAX and PSX-SCENE.
I guess this method was working up untill 3.55, anyways since i was not sure I wanted to take my chances by getting support here.
If not, then can this AVR Key be used in any other manner to support the downgrade process.
Thanks for your inputs.
