HP 840 G8 Bios Unlock

[Blaze Tech]

Hi everyone, I flashed the patched file but it gives me the error lights on the keyboard and it doesn't turn on! I checked the checksum and everything is the same as the file you gave me..

Upload the 32mb ec bios file

Sorry but the mistake was mine because I had damaged a pin on the motherboard Everything is ok now, it works perfectly, thank you very much.

do not touch the EC.
first boot press f10 apply factory defaults and restart, 2nd boot reset security settings to defaults and exit.
use BCU. you can permanently disable Absolute lock in BCU.
