Blu-ray Patched Lv2diag for Downgrading PS3 Firmware

Whatever you do: DO NOT TRY THIS ON 3.56! If you do you’ll forever remain in Factory/Service mode — the point of no return. Maybe someone, some day will figure out a clever way if you’re stuck, but till then, you’ve been warned. The idea behind JaicraB’s patched Lv2diag.self is that your Blu-ray drive, should that be broken, will be skipped during the PS3UPDAT.PUP scan, which means you can downgrade/upgrade your firmware without a functional Blu-ray drive present. Personally I didn’t know a broken Blu-ray drive would prevent you from doing that, but hey … you learn something new everyday. The other reason this patch was created is for PS3′s with a 256MB NAND. If you recall downgrading a PS3 with a 256MB NAND will render Blu-ray playback inoperable. This aims to fix that when downgrading from 3.50/3.55 to 3.41. Again: do not attempt a downgrade from 3.56. This Lv2diag.self is to be used as the first in any PS3 downgrading procedure. Remember two (2) “Lv2diag.self” files are used: 1) for performing the actual downgrade while in Factory/Service mode; and 2) for exiting Factory/Service mode, returning your PS3 to normal.
