Hi, After a bios update from f36 to f76 the laptop no longer boots, I also tried the recovery but even if it completes it now remains a black screen and does not even enter bios. I attach the backup of the bios before the recovery attempt and the serial numbers of the laptop, thanks to anyone who can recompile it.

Thanks but now it does as before the restore i.e. it restarts continuously.
Now I attach the bios where it remained on a black screen that was after the previous one and I make a correction on the prouID which is 2SX49EA#ABZ.
PS: A question: and if I reinstall the bios F36 can it start or not?​Comment

Thanks, with this the laptop starts but all the info is missing, how do I restore it?
PS: Do you recommend updating the BIOS as it is now or is it not worth it for me?​Comment

Hello. I saw a similar post but I tried and failed.
Windows update forced a BIOS update on my HP 250 G6, after it restarted black screen. In the caps key 5 long blinks and 3 fast blinks. Basically its bricked.
I tried HP USB Recovery Tool but doesnt event show up.
I used the CH341 with the 1.8V adapter to backup the bricked bios just in case. Then I downloaded the official bios from HP website. After decompressing x5 .bin (with their .sig) files were saved. Tried flashing all of them but the Caps key still blinked.
I dont really know what´s happening because with the correct bios it should boot up.

Hello everyone!
The official HP update (sp156143) destroyed the BIOS of my HP 250 G6. The upgrade took place from F.73 to F.77
I have read out the defective BIOS and now ask the forum members to correct the defective BIOS - if possible.

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... -

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...
