Hi, Thank you.
Old Bios ME Updated - tablet does't start at all.
Latest Bios Edit - start for a second then shut down.
I think my original bios corrupted not only ME region.
I found working bios with dirty ME. Tablet boot on but very slowly.
Could you clean ME region and transfer my serial number ets. to new file? Serial number is: 008162402751
Thank you.

Hello, vikrep your bios region was missing, I didn't pay much attention. The version I added now includes the latest version of Bios and ME "High Power". Also your serial number is included. And then Download and install the automatic firmware update from the link I gave, it will work faster. Pls give me feedback Best regards

Hi guys! Thanks everyone. Bios.bin from CMDFlea works great. Unfortunately, I found another problem. The tablet starts working only if I warm up the eMMC chip. Maybe this causes a BIOS failure if the tablet hangs at random times. Does anyone have experience replacing eMMC memory? Physically I can replace it, but where can I buy it? ThanksComment

Surface go 2 1901
0B33PGC213633F SerialNumber
QTFM089518003209 Board Serial Number
This tablet briefly shows the logo and then shuts down.
The battery and charging voltages are fine, but I can’t access the BIOS settings.
It’s very likely that the BIOS file is corrupted.
Thank you very much in advance for your help.Comment

Hello everyone, I happen to have a Microsoft Surface Pro X 1876 in my hands. It was brought to me by a friends which happen to have taken off the bios chip to test another motherboard. Upon putting back the bios chip on the original motherboard, The PC is stucked on Windows logo and won t boot to bios or anything. I suspect that the changes of bios chip somehow corrupted the firmware inside. Is the hypothesis correct?
Also i extracted the bios inside the chip which was on Winbond 25R128JWPQ you can find the file attached if you can fix it (if possible, I would like some insight on... -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

Hello everyone,
I am requesting urgent assistance to unbrick my laptop, a rebranded TongFang GK7MRFR chassis. The laptop is completely dead following a faulty in-OS EC flash attempt.
I have successfully used a CH341A programmer and can read/write/verify both flash chips, but using my backups/extractions has failed to restore power. The root cause is likely a corrupted Intel Management Engine (ME) region or an incompatible EC/BIOS pairing. System & Hardware Details- Barebone / Chassis: TongFang GK7MRFR

Hey. Sometime ago i bought broken surface pro 4 supposedly it was dead. But turns out it was just a faulty charger. Although when it powered on and after all updates, touchscreen didn't work it also doesn't work in UEFI. On my original bios in device menager it shows yellow triangles on Surface ME and Surface Touch, hid-compliant touchscreen was missing. I already replaced touchscreen and touchscreen board, i've broken the orginal screen when trying to open surface. I already tried diffrent bios files from internet. With the latest one i was able to install the drivers for Surface ME and Surface... -
Hello everyone,
I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.
When the laptop arrived (without a charger and SSD), I connected a charger and confirmed with a multimeter that it was charging the battery. However, when I tried to power it on, only the backlight of the secondary display came on. There was no image, and it didn’t boot into the BIOS.
I decided to try flashing a new BIOS, but since I didn’t want to desolder...
