Hi
The usual, eBay seller failed to mention the password lock on the BIOS

Thanks, hackeraj! When I tried to write it back (via fptw64 -f 027853301557_unlocked.bin), using Administrator account, I got the following error:

Error 167: Protected Range Registers are currently set by BIOS, preventing flash access.
Please contact the target system BIOS vendor for an option to disable
Protected Range Registers.

FPT Operation Failed.

Any ideas on how I can write it back?

You must backup by programmer, do not use any software because backup by software does not complete bios file.
