Good evening. Thank you for your answer! Yes, at first I read the chip unsoldered with pliers. Then I unsoldered the chip and deleted it. I programmed another bios from the depths of the Internet, but my computer did not work. The caps lock blinks like before. Now I need a completely new and correct bios dump file. I am not smart enough in this matter to prepare a new bios myself. Maybe one of the bios posted on this site will work for me? Thank you!Leave a comment:

the bios posted is half empty...The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..
here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

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... -
Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

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 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...
