Acer Nitro 5 / AN515-44 - need BIOS file

[Mullin5478]

the chip

Update / Still Stuck

I’m still unable to get the machine working. Here’s what I’ve tried since the original post:

• Swapped RAM with known-good sticks. (no change + different slots)
• Tested on external monitors (HDMI). (screen is on then when i plug it in goes straight to sleep)
• Reflashed the BIOS multiple times using fresh files from Acer. (no change other than tuyen821991 uplaod made the blue led flash and turn off for few times)
• Extracted and flashed a 16 MB image cut from theabobios.bin.
• Attempted the crisis recovery method (Fn+Esc) with no success. (fans go full speed that its in recovery mode but never seems to do anything looked in the file seen that its looking for BIOS.BIN didnt work also FH51Sx64.FD , FH51S.FD , FH51Sx64.rom FH51Sx64.bin etc ... also abobios.bin renamed too )
• also followed this sort of https://github.com/ny4rlk0/BIOS-ACER-NITRO-5-AN515-45 but still no luck

The result is always the same: fans spin get faster over time till full speed slowly no heat tho , keyboard backlight reacts, charger/beep works, but the CPU stays cold, no POST, and no video.

At this point I’ve been working on it for several days and have run out of ideas. Any advice or guidance would be greatly appreciated.

THE ONLY thing diffrent is the blue led light flashed few times after the updated bios i was given but then that could just be my bad soldering ? then started doing what it did before
