just brought my ps3 320 gig CECH-2502B, it came with 3.50 fw preinstalled. i get to the factory mode just fine via AVRKEY doogle
but when i put in file 1 n mod 3.41 fw it results in constant blinkin of the green light on the ps3. even after an hr nothing happens so i'm forced to turn it off.
it works fine when i try 3.50 fw and file 1.
