[UPDATE] I succesfully unbricked my ps3, yesss


sometimes, if you wanna do something right, you have to do it yourself

what I did was, I soldered the SBE point to the Nor Tristate, which is located here on VER 001 motherboards:
Ps3 Playstation 3 PA0 NOR Tristate Point VER-001 Motherboard - YouTube
Then, I took my copy of the bios, in this case, the one that caused the brick (3.55 in my case, it has to be the same firmware that you had prior to having the brick AND make sure is error free) then, on the e3 flasher, flip the FLASH FUN switch up (the rest down) and then hit START on the E3. After that, it asked me to connect my controller, and Bingo! I was back on 3.55 again! And Dual boot is back too 3.55 <==>4.11. Awesome.
I hope this doesn't happen to you guys, because the downgrade process gave me a YLOD, but if you do, I hope this help you as much as it helped me
P.S.: Thanks to those who tried to help me too : )
