After Testing with some bricked Slim consoles ( from updating to CFW4.21 ) with different friends and testers around the world,
I can confirm that Bricked consoles can be recovered back to CFW3.55 even if you didn't have a NOR Dump/Backup .



Requirements are:
1- a Hardware Flasher so you can read/write to the PS3 NOR flash
2- A Dongle with PSgrade payload (any old jailbreak dongle + PSGrade hex will do) used to Enter Factory Service Mode (FSM)
3- Rogero CEX3.55 v3.7 PUP




Recovery Procedure :
1- Dump the current NOR Flash of the bricked PS3 at least 3 times using a hardware flasher (Progskeet / E3 / TEENSY++)
2- Verify that it is properly dumped and you have a valid dump ready to be patched with the downgrade patches.
3- Patch the dump using Rogero PS3 NOR Auto Patcher or any other Program available.
3- Flash the Patched Dump back into the PS3 NOR using the Hardware flasher.
4- From this point you can continue as a normal Downgrade Procedure by entering Factory Service Mode using the dongle and Flashing Rogero CEX-3.55 v3.7 from the USB stick.

It´s a full Brick???
Maybe i´m saying something wrong, but can´t you make a way to red screen error to force auto ofw restore? I remember that one time ago, after a vacation with long time without use, my ps3 reverse to ofw 3.50...
