Re: Need bios for Lg Gram 1XZ90
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)↵

Re: Need bios for Lg Gram 1XZ90
Hi hoaca388, thanks for your help.Originally posted by ;1168498
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.

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hi all,
My Samsung Galaxy Book 2 Pro 15.6-inch laptop has no display and won't boot.
The charging red LED lights up, but the charging screen doesn't show any indication.
When I press the power button, the blue LED cycles on and off three times, then the screen doesn't turn on, and the device won't boot.
(I've tried removing the battery and resetting the device, but the issue persists.)

Hello guys,
could I please get some help cleaning the ME region of the attached Zbook 17 G1 bios dump (CH341a, neoprogrammer, chip-desoldered, dumped twice, identical checksum)?
Symptoms, delayed BIOS post (ca. 45 secs.) keyboard not working, touchpad not working, booting linux live, console says "Management engine not configured".
I tried following the ME firmware cleaning guide, but whatever Flash Image Tool version I try, I get the same error:
Error 10: Failed to open with processed commands.

Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM
