Re: Flash bios
I use a tl866cs universal programmer. They read quite a lot of chips. Ch341 is cheaper and can read most bios chips if you only want to program bios.
I use sop to dip adapters desolder bios. Put it in the programmer and back it up onto the computer. I select tbe right chip and there is a dropdown menu to read the contents. It just reads the contents of the chip and thats a bios dump.
I would then open the new bios file and click program to write to the chip. Solder it back to the main board and it should hopefully work.
I can try taking photos of the process if you want. Let me know
Dump file is the output contents of what was read from the bios chip
Hope it helps. My English isn't to great. I hope readable.... -

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.)
NoteBook Model name : Samsung NT955XED-KK51G(Galaxy book2 pro, i5-1240p, 15.6inch AMOLED)

Hello everyone.
I have L460 Type 20FV (2 X 8MB bios chips) with no boot issue after BIOS update (black screen with restarts, common issue on this model + BIOS update).
BIOS dump(s) from this post https://www.badcaps.net/forum/showpo...7&postcount=27 makes the laptop boot absolutely fine, no delays, etc..
But there is an exclamation mark in the device manager for the LAN card right after fresh OS installation - LAN naturally doesn't work. I saw requests like "BIOS: fix LAN" on other sites.
Could someone point on a direction... -
Hi, I have an MSI PRO B660M-G DDR4 board with damaged BIOS and i need a bios dump from a real board, along with MAC, UUID and Serial Number info (eg. a BIOS screenshot and pictures from the board stickers).
I need to reconstruct the bios on my board, based on another bios image form a real board - meaning a bios image containing MAC address, UUID and Serial number. A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored. Tried with a similar board, but there are too much differences, and the stock BIOS is missing a lot of...11-17-2023, 10:56 AM -
Hi all! Tldr: need a bios dump (.bin format) for K6604J (rtx 4070 and i9-13980hx)
Longer story: my vivobook stopped booting after i switched out the thermal paste. I think the BIOS got corrupted. Everything i tried didnāt work until finally i decided to buy a CH341A BIOS programmer and just send over the BIOS directly from another PC onto the BIOS chip. I connected fine and backed up the existing BIOS, but i canāt find a clean BIOS thatās a .bin format. And I tried using UEFI software to extract all the files from the ASUS BIOS .exe file and get to the .bin but it was a .302...
