MSI PRO B660M-G DDR4 - real bios dump from board needed (no stock bios)

by DynaxSC

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).

A stock BIOS is not suffiecient, as it is impossible to discover where the MAC, UUID and SerialNumber are stored.

[REQUEST] Fujitsu Lifebook E5513 – Full BIOS Dump Needed (.bin)

by TacticalFahrrad

Hi everyone,

I'm trying to recover a Fujitsu Lifebook E5513 (most likely 2023 model) that was bricked during a BIOS update. The update was interrupted (probably due to power loss), and now the laptop is stuck in a boot loop showing "PBB rollback" / "SBB rollback" messages.
BIOS access (F2) and Boot Menu (F12) are no longer possible – the system instantly reboots after the rollback messages.

I extracted the official BIOS update package from Fujitsu (contains FJNB2FD.CAP, ~18.7 MB) and tried tools like UEFIExtract, but it seems to only contain...

ASUS TP500LA BIOS request/repair/merge?

by jbonavita

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized

Things I tried

1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...theory/trouble...
