(adsbygoogle = window.adsbygoogle || []).push({}); Hi guys... I was downgrading a ps3 (JSD-001, CECH-2503B, 320gb)
Managed to get a successful dump and then I patched one of the three I had. Downgraded it to 999 downgraded and toggled QA.
Worked perfectly turned it off and went to bed, woke up and turned it on to finish and it wouldn't turn on (turns on, then off. NO RED BLINKING LED!! No red light at all)
So I tried reflashing the original dump and it did the same thing... Flashed the patched one and it stays on but I get no screen and no HDD activity... I followed the pinned post on how to downgrade (as its been a while since I did) and now that has happened... Any suggestions on what to do?
Any help is GREATLY appreciated!!

Bump!

looks like a brick! is that model number even compatible with downgrade?

Yes, downgradable to 3.50

hmm try safe mode and use rebug 3.55.4 downgrader this is the better downgrader rebug 3.55.4 OK
