[vahid.ch]

hi all.
I have an Amtel (AT90USB162) and I want to downgrade my PS3.
I flash my Amtel and after that I follow the steps which has been told by sites.
I copy my PS3UPDAT.PUP and Lv2diag.self(first one)into my USB and turn on my ps3 .
in 3 minutes my USB and my hard starts working after that it does not work and my green led begins flashing but my PS3 does not turn off.
I waited for more than 2 hours but it did not turn off.
any idea?

Anyone having problems with the 3.41 flash not completing (flashing green light, never completes, then dead system until flashed 3.50) then its a problem with the original download linked in the article, although it appears to have been deleted.

The time stamp on the main file was July 2010 so I guess its the original unmodified 3.41 update, where as others are time stamped 11th Nov 2010.

I flashed back to 3.50, ran the second file to take it out of service mode then started again but with the modified file. You may possibly not need to come out of service mode, but I did.

I successfully downgraded to 3.41 now.
