820-2915: Stock on Progress Bar

[macRepairAmb]

Hello

Working on a 820-2915. Had two issues originally, first was GPU related, lines across screen, which has been repaired (rebelled GPU).

Second issue is it boots up to progress bar but never boots completely into OS. I've check and confirmed no corrosion present or sign of liquid spills.

Could anyone please assist with cleaning up the EFI bios file that i've attached. I can't seem to find a clean ME region for this version.

You can have GPU issue too; if reballed chip, not really new...

Get Tiresias GPUkiller and disable GPU.
Latest Medusa programmer can also disable GPU; but only survives untill first PRAM reset...
