I had a rsod ps3 on 4.11. I used the e3 and downgraded it to rogero v3 with 4.11 spoofer. When i powered it up it still had the rsod. So i updated it to the norsod.pup 3.55 which is the only update that actually will get past the rsod. I have done this successfully on 2 rsod.
Anyway, I know that this is the old way of trying to fix the rsod, as this doesn't actually fix anything, it just bypasses the check for rsod. I wanted to get on a proper firmware and try fixing the rsod with the factory service mode lvl2.diag rsod fix. I wasn't sure if i could go from norsod.pup to 3.55 ofw without qa flagging, so i qa flagged it and turned on the update bypass thingy that e3 said to turn on.
Then I updated to 3.55. It completed then turned off. Now when i turned it on, it is bricked. It actually turns on then ylod then shuts off. Oh... here is the bad part. I have good dumps of it on 4.11 and rogero v3, but when i went to norsod.pup, i wasn't able to get a dump. The damn solderless clip must have lost connectivity, and i was too eager to get it working to take it back apart for the 3rd time, so i just went with it.
Perma brick i guess. Any input would be helpful, even if it is calling me a dumbass for not waiting till i had a good dump on the current firmware. I knew better and need ridiculing.
