I am in the process of flashing the bios on my bricked lenovo thinkpad p53s. I am using a raspberry pi and a pomona test clip, all is going well and i can read the flash chip as well as remove the old bios but i am having trouble figuring out what file is the new bios. I extracted the .FL1 file from the most recent bios update (n2iuj38w.iso) from the lenovo website. Using UEFITool I can explore the contents of the .FL1 file but I don't seem to know what file to write onto the flash chip. The only file that has the same size required by the bios is the padding. I am pretty stumped so if anyone had any idea on how to proceed that would be greatly appreciated.

My laptop serial number is PF292CDY
And here is the backup bios file
This all started when i made the mistake of putting special characters in my bios password. All that shows up on my computer when I boot it is "0199: System Security - Security password retry count exceeded" Is this the right process I should take and Is my computer recoverable?Comment

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 Thinkpad T560 Which has corrupted BIOS. I have acquired Ch341A SPI flasher to program the BIOS externally. I see that to program the BIOS, i need a bin file for the BIOS. I was able to extract the .exe file of BIOS from Lenovo given here in this link:

In the extracted files, I see that BIOS containing file has extension .FL1 and I need to extract or convert it... -
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...
