pioneer firmware downgrade ?

[fatbloke]

Is there a way to down grade the firmware from 1.3 down to 1.21 or
even 1.0 to see if it will help read and write certain discs, I've looked thro the forums and I'm unable to find the answer, please help.....

Hi,

better lok in the forum section there. Just look through the "stickies" and most recent "Firmware hack for 105".

- possibility to downgrade
- hacked new 1.30 firmware (RPC1 + 2x speed with Ritek G3)
