Hello everyone,

I recently bought a non-working Asus Zenbook Pro Duo OLED UX8402ZA that was listed for parts only. The seller mentioned that it had no display output but that the charging lights worked.

• Followed the exact FlashBack procedure (correct port, renamed file, standby power only).

Issue:
The FlashBack LED does not blink at all — no activity whatsoever. Further investigation


Because FlashBack didn’t work, I:

Hey guys, I have an "ASUS TUF Gaming A15 FA506NF (2021)" that's locked with a UEFI password, I need to reprogram the BIOS chip but can't find a clean ".bin" file for this specific model, I've tried the official BIOS updates from ASUS support page, but they're 32MB updaters that don't extract to a usable 2MB .bin file for direct chip programming.

Does anyone have either a clean 2MB .bin dump of this model,...
