820-3476 BIOS HELP needed =)

06-25-2020, 02:55 PM

Hello!

I have a 13' MBPr Mid 2014 (board number 820-3476) that shows ''serial number not availble'' under ''About this Mac''

I read the BIOS file and tried to enter SN in HxD, but the section where I change the SN is not even availble in the BIOS-file :O

Can somebody please help me fix this, or fix a ''new'' BIOS with clean ME?
Would hugely appreciate it because I have no idea myself how you can fix this

Here is the original dump, not sure it works though...

The serial number is supposed to be: C02P61N5G3QQ

🛠️ MSI GP75 Leopard MS-17E71 – No Display, Deep BIOS/EC Troubleshooting

by macabook
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

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).

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...

HP Elite Dragonfly Bios Crashed - HELP NEEDED

by techlab
Hi Guys,

Looking for some help with an HP Elite Dragonfly.

The customer explained it was updating the BIOS, the flashing completed, but afterwards the laptop wouldn’t power back on.
- The laptop has no power but does take the correct voltage.
- It shows 5 flashes white/amber, which indicates a BIOS issue.
- I backed up the original BIOS to extract the feature byte etc.
- I then flashed the BIOS with a clean version from HP’s website, but the laptop still gives 5 white/amber flashes.
Just wanted to pick your brains on this — has anyone come across this before or...
