..went halfway...then stopped..etc.etc...wtc is up with that trying to downgrade..i don't get it...atleast u have a valid backup and should be up&running in notime
for the new dumps u made u can see as playerkp420 already posted..the E3CLIP isn't firmly connected all the way....resulting in bad dumps every time!
to get the ps3 out of the brick, keep backup1 save+the patched one..those are valid! but make more backups first, restoring the valid one like this with a e3clip not touhging all the way/all pins wont unbrick it, so make sure the clip is fitted....99% where the errors coming from..put the sucker down and keep it down
