The BIOS that you have sent me is not working. I am thinking that the end part of the BIOS is corrupted. Can you send me another version of the BIOS?

I've tried the same image with no luck, both from here and linked thread.
The machine itself powers on via TB3 port only with fan spin and keyboard backlight, 2 second later only power button LED stays on and then it power cycles. Could it be a deeper problem with the logic board?

Your old bios does it have the same problem if it's than you have a hardware problem but you can upload your Bios to clear it.

Was the same when I got it, interesting to note is that the laptop does not power on from the marked Type-C charging port. ONLY Thunderbolt 3 port works and does charge the battery. There's also no backlight on LCD or beeps from speakers.

I'll attach the original dumped BIOS

Do you have a dump from the second SPI that's near the Thunderbolt controller?
