There is no bios for your model on the LG homepage. Try this clean ME file (this is your bios file with ME region cleaned)

Hi hoaca388, thanks for your help.

I have tested the cleaned bios and it behaves the same as before.

I can measure a few pulses at pin 1 of flash chip and also all voltages rise, but power comsumtion is very low. (about 60 mili amps)

After all tests with the cleaned dump, I have reread it and all data in bios are there without any byte change. Seems that pch doesn't modified the ME region.

Probably the board have other problem, or the bios is corrupted in other part than ME region.

I will try to get de schematic for this board and measure plt_rst and other related signals.

Perhaps i will be lucky and get the schematic, or somebody in the forum have another good bios

Many thanks for your effort.
