Oh, so you didn`t save the original bios backup and just wrote another one over it ?

correct...

i have a problem after updating the TPM firmware, after successfully updating TPM and rebooting here is the problem, my laptop can't enter the bios anymore
after trying several BIOS files from this forum, i got a file that can turn on my laptop again.

but the other problem is:
- TPM could not be initialized every time booting must press F1 to continue
- Missing TPM feature in BIOS
- Service TAG and Express Code changed different from before

Use an SPI programmer to make backups of the bios chip(s) and post them here.
