Dudshl · 12-15-2011

One more console which briks when I try downgrade it with E3-flasher.
CECH-2504A data code 1A. Factory firmware 3.56.
http://www.megaupload.com/?d=GYZ8PHFV - there is my dump (3.56).

How can I downgrade it? Teensy or progskeet?

one more problem:
I dump NOR, tried downgrade it - it bricked.
I restored NOR with first 3.56 dump - it booted correct.
I updated it to 3.73 and tried downgrade it - it bricked too (I did not make 3.73 NOR dump before downgrade).
And now when I restore first 3.56 NOR dump - console bricks too!
Why? How can restore console?
