Hello all
Model - Satellite P55-A5104SL
Mainboard - VGSG MB Ver:2.1
All flashing done w/CH341 adapter & EEPROM chips off board.
PROBLEM:
After updating from BIOS 1.70 to 1.90, it shows Toshiba logo and halts. I narrowed it down to a possibly corrupted BIOS. How do I know? There is no similar machine in the forums, so I tried a dump for another model with same mainboard (L50-A-19N) provided by @ala_borbe in this thread. Flashed this on both BIOS & ME_FW chips and the laptop came to life again! BUT, with these symptoms:

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.

🧩 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

Hello, the bios on my Lenovo TD350 ThinkServer got corrupted during a bios update, the bios restore function killed the Server.
I need to flash the bios inside the MX25L12835F SOP8, i have already desolder the chip and solder it into my SOP8 adapter and read it with a ROM programmer.
I use the innoextract 1.9 software to extract the bios file from the .exe file that i download from lenovo website, can you help me edit the Hex file (removing the Index part and resize the file)?
