Hi,

I need the BIOS dump for the Tshiba Satellite L875D-7332 notebook motherboard. The wrong BIOS is written and I cannot downgrade.

Can anyone help me in this situation?
hello. What is your part number, ex. PSKXXX? Do you have backup?

Hi,

The Part number is PSKFQU-008003. 


About the backup, unfortunately I don't have it. The notebook I already bought used and already had the following problem:

It only has video on an external monitor, in legacy boot mode. If you change boot mode to UEFI, the notebook screen turns on, no video, but working.

Any suggestion? Thank you for your help

I already tried version 6.10, it didn't work. Remained the same problem.

Older versions don't install because of file size, even disabling comparison.

I'm suspecting the EC version, but I don't know how to downgrade EC

If I record a bios with the updated cpu microcode, can it solve this problem?
