Need Clean BIOS/EC Bin File for Lenovo ThinkPad Yoga 11e - Stuck with 0275 Error CMS

Hello everyone,

I am attempting a repair on a Lenovo ThinkPad Yoga 11e that is currently stuck at boot with the error: "0275 error CMS" even after setup new bios battery and will not allow me to enter the BIOS/Setup.

This is a critical issue that I believe requires flashing the BIOS chip directly using a programmer (e.g., CH341A/RT809H), as standard software updates or resets are not possible.

I have opened the laptop and identified the main BIOS chip...

Hello Everyone,

I have HUAWEI MateBook X Pro 2019 (MACH-WX9) whose BIOS got corrupted i beleive. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need BIOS bin/hex file which i could use to reflash it externally via the flasher tool.

It seems like the support page of this model no longer exist: https://consumer.huawei.com/be/lapto...ro-2019/specs/

In the website, you can only see specs etc.

I have not tried to extract the BIOS dump yet as I want to see if there is any ray of sunshine...

Hi everyone
I noticed on the Xgpro software the BIOS backup files have extra bytes at the end when reading some chips, this is because the Xgpro software also reads the OTP region of those flash chips, and by default will append that region to the saved file
Programmer models: XGecu TL866II Plus / T48 / T56 / T76

Example: GD25LQ128D (1.8V), IC size is listed as 0x1000000 Bytes (16777216 bytes) + 0xC00 bytes, those extra 0xC00 bytes will be appended to the end of the saved file by default, resulting in a file size of 16780288 bytes
There's also an extra OTP Secu.R...

Hello, everyone!

I've got an HP ProDesk 600 G5 Desktop Mini with an i5-9600T with vPro / AMT. I updated its BIOS one day via the UEFI interface (not in Windows) and I presume the update failed. The PC would sit with its power LED on solid white, no output. Unpacking the BIOS provided by HP to a USB and booting with Windows-V or Windows-B pressed didn't help with anything.

Therefore, I got a CH341A flasher. The PC has a 16MB BIOS (GD25B127DSIG) and a 32MB EC chip (GD25B256DFIG).

I saved my initial bricked 16MB BIOS (attached ) and tried flashing one I found...
