You havn`t made a good backup,it is only 6.2KB compressed. Read this -> https://www.badcaps.net/forum/troubl...21#post1622421
Make sure that the dumps looks good, i.e. not filled with 0x00 or 0xFF. After compression, if the file has a size of only a few kilobytes, the EEPROM was most likely not read properly.

The Samsung S49CG934SU monitor does not power on - no LED indicator activity and no response to power button. However, when 21V power is connected, it immediately draws 0.8A of current with no display output. The motherboard processor gets warm, and there is continuous reading activity from the W25Q128BV BIOS chip.
Suspected Cause:
I suspect the BIOS may have been corrupted during a power interruption while updating the firmware. The official website provides firmware updates, but they can only be installed via USB flash drive.

Hp Probook 450 G7 s# SCD0348W35 had a locked BIOS. Bought BIOS and EC chips off Ebay that were supposed to match this machine - the 450 G7. Flashed in the BIOS on chip i bought using a CH341. BIOS unlocked next boot. Some error to contact HP. Entered BIOS and reset to system defaults and rebooted. Machine worked fine but every cold boot the contact HP message popped and everything else worked as fine. Assumed the error was from EC chip not matching BIOS that i just flashed in. So i flashed in the EC that was supposed to match from the EBay chip i bought and instant brick.

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.
I tried to add a custom secure boot key (for secure booting Linux) to my bios, but after this, my laptop bricked. After adding secure boot key (via PowerShell) and enabling secure boot my laptop turns on, shows HP logo, and after 5 seconds it turns off and on, and it repeats forever.
My goal is to either turn off secure boot or remove my custom key from BIOS dump.
I'll attach my bios dump (version R79_011700) from my bios chip 25b127dsig, my keys (PK/KEK/db), and bios dump from another HP ProBook 445R G6(I found it on this forum. URL: https://www.ba...
