[HELP] Nitro 5 AN515-54 BIOS

Hello,
I flashed a modded BIOS on my laptop, all steps are going fine, but laptop don’t boot.
The laptop power on with keyboard and fans, then power off, then power on again and that’s all…

I tried with several versions of CH341a for windows, AsProgrammer, flashrom on linux, each time, flash and verification is OK, but result is the same.
I also tried to recover BIOS with FN+ESC without success.

The BIOS chip is an XMC XM25Q128AHIG.

I don’t know how to figure out this issue.

Thanks in advance !

have to managed to boot your laptop again?
I not you can try the bios form my Nitro 7 !!
