Re: Lenovo L460 LAN issue after BIOS dump flash
No they are Linux programs. I use them on Ubuntu 20.
You can find them here :

Re: Lenovo L460 LAN issue after BIOS dump flash
Hi!
Read here : https://www.badcaps.net/forum/showthread.php?t=103526.
There are several programmers and software for them.
And as method u can use a clip for onboard programming or soldering iron or hot air for de-solder the BIOS chip, read it first (for backup) then erase and program the modified version.

Re: Lenovo L460 LAN issue after BIOS dump flash
hello guys!
I dug for a long time and figured out bios thinkpad l460.
I have such a situation: the bios chip is out of order. Nothing from all the forums brought any results. after numerous searches, I assembled the uefi assembly to make it work.
1. the problem is the lack of startup at all (solution on the bios chip when flashing "status reg" qe=1)
2. I will not comment on intel ME, I found about 30 working versions of 11.x.xx.xxxx I think there are a lot more of them.
3.!!!! wired lan not work error: what I just didn't try in the available bios versions. solution: flash image tool v11 >>> network and connectivity>>>wired lan configuration>>>Gbe PCIe Port Select>>>Port5 to Port4. some may do the opposite.
please use the solution
gbe region contains only the address and model of the network card and its id.
4. encountered system friezes: freezes are short, barely noticeable. solution - me 11.8.83.3874
5. bonus found where the lenovo logo is hiding)))Comment

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 -
Hello everyone,
I’m currently working on a dead MSI GP75 Leopard (MS-17E71) motherboard (i7 CPU, NVIDIA GPU) with a no display/no backlight issue initially. After extensive investigation, I’m at a critical stage involving EC firmware, BIOS/ME region interaction, and possible deep corruption. I'm seeking advanced insight from anyone with experience in EC/BIOS sync issues or PCH-level behavior. Here’s a full breakdown:
🧩 Initial Issue- Board powers on (fans spin, keyboard lights up and can be adjusted, caps lock led lights), but no display or backlight
- External display (HDMI) shows

After a bios downgrade, the keyboard's RGB stopped working, now in the device manager the STM32 Bootloader device appears, I discovered that it is the rgb microcontroller, I believe that (STM32 bootloader) is because it does not identify the bios file (UEL2)
Does anyone have the BIOS dump (UEL 2) of the Dell G15? It is responsible for the RGB keyboard.

Hi,
I need a BIOS dump for MSI Z590 PRO WIFI from a real physical board, along with MAC address and serial no.
It must be a dump from a physical board, as it contains personalized data eg. MAC Address, UUID, Serial no.
I have a board which has lost the BIOS contents, I have the MAC and serial to this board, and need to insert it into the another BIOS image. To do it, I need to have a real image from a real board, as the images from the MSI site are without this data. The only way to find where MAC/UUID/Serial is located in the BIOS is to have a bios...11-06-2022, 05:22 PM -
Following this guide (https://www.reddit.com/r/thinkpad/co...g_and_flashing) i re-flashed my t480s BIOS using an external (CH341A) programmer. The flash didnt work, so i reverted back to my BIOS backup successfully. The BIOS in the chip and the BIOS backup file are identical according to windows' file compare. The revert, however, didnt work: the only thing the computer does is flash the power button 3 times when AC power is connected. I've tried unplugging the CMOS battery, holding the reset button and holding down the power button- no signs of life....
