I have already flashed the original bios (backed up from the start) and it still doesn't want to turn on, I was checking the computer and apparently everything is in order, but, checking the ch341 programmer, I noticed that the clip with which I hold the bios doesn't make very good contact and I have my doubts, testing in the neoprogrammer software at the time of checking it gives me a buffer address verification error 0x90 something like that, investigating a little it seems that the ch341 device doesn't receive enough voltage and that's why it gives problems when reading/writing, I have already made the purchase for another device and an extra clip to test, I'll be back after doing my tests and reporting how everything went, I really appreciate the help.

Hello! A few days ago I wanted to unlock this laptop to be able to activate the developer mode, they helped me here by giving me the already unlocked bios, but when I flashed the bios with the (unlocked) bios it didn't turn on anymore! The led only turns on once when I press the combination (Esc + refresh + power) but it doesn't even start in safe mode, so I tried to flash the original bios again and it still doesn't turn on and it does the same thing!! Then I realized that the clip I used to read the chip wasn't holding well and that maybe I didn't read the backup correctly which I was supposed to do right, some things I already tried:
-I have access to another laptop that is the same as this one that is functional and I was able to extract the bios, I tried to flash it and it still doesn't turn on.
-I changed the clip (I bought another new package) and I tried to burn it even on another PC and with the same result
-I checked the BIOS with an HxD program to compare and I see some notable differences, which make me think that it is corrupt.
I can unsolder the BIOS since I already have the computer, but at this point I don't know if I can change anything.
I am attaching the backup of the BIOS that is supposed to be the original.Comment

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.)

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... -
Hi,
I'm looking for the original BIOS file for the Medion Akoya S6445 – model MD61280, preferably in .bin or .rom format for flashing via CH341A programmer.
The BIOS chip is a GStek GS7166 (25Q64 compatible, 8MB SPI).
Does anyone have the correct BIOS file or know where to get it?
Any help would be greatly appreciated!
Thanks!
