M1 Firmware files for BIOS REFLASH

vahihapehe

Hi I have a Beelink M1
SN: EN508SLF70016
M1-C-864NDBW64PRO
and BIOS BIOS Version/Date was American Megatrends Inc. 00.14, 12/06/2017

Suddendly today the device shut down with windows update, and did not turn on.

If I press power button, blue light comes up but no video at all (no vga or hdmi). When on, if I press power button for 6 seconds, it turns off.
When turning on, USB flash attached is flashing for some seconds if it's trying to read something, but nothing more.

I pressed every keyboard key, but nothing happens.
I've tryed to remove CMOS battery and let it settle down for minutes, but not resolving.
I've tryed with cmos pin hole, but not resolving.

Please give me flash file so that I can flash it (with SD card or USB attached to other PC).
I think it's a BIOS issue.

Thanks, regards
