just use downgrade method, puting updat.pup to root in usb drive and use ps3 jig. ps3 wont show any screen on this proccess, only inticators are flashing lights :D
i flashed the NOR with same FW again that worked before, but still canīt TURN ON the PS3. flashed it few times, verified it, but result is same: PS3 TURNs ON for 3 seconds, then the yellow HDD LED shortly litīs, and then it fully POWERīs OFF(after that even the red POWER-LED is OFF, need to press power-button twice to TURN ON again).
so no way to make a firmware update from a usb-drive since the PS3 isnīt powering up/booting correctly.
