HP 455 G7, D0X9MMB8F0, rev.F

[hopkok]

Hi, I am looking for bioses for HP 455 G7, D0X9MMB8F0 rev F, I found some on web, but different Bios chips and they did not work. Another service erase both chips, so empty chips on board. Customer said, before laptop did not boot at all, just stuck on HP logo. He tried to remove all drives than can access BIOS, updated to last version, but if any device connected back, just stuck on logo. Now he is asking service for files, but with no luck.
So I decided to ask here if anyone can help. Now laptop completely dead of course.

My bios chips are on attached photos.

I searched forum with no luck for my bios chips.

Many thanks, hope I did not brake any rules.
Have a nice rest of day.

Actually do not have backups as I said, chips are empty. Hopefully get it from service that tried to repair and finally deleted BIOS chips. Serial number is: 5CD028LPQ1

Hi, I'm looking for the same BIOS and EC ROM as OP. My laptop a 445 G7 (same MB as 455 G7) stopped booting, white LED on charge port for a second and then everthing is dark. If it's a bad BIOS then maybe it can be saved. Unfortunately I destroyed the chip (W25Q128JV) with the big BIOS written on the MB while removing with the heat gun, was my first attempt to remove such chip. The chip right to it (GD25B127D), I could remove and read with the the XGecu T48 programmer. Bought a new empty BIOS chip (W25Q128JV) and hope to get at least to the same state as before. I assume that W25Q128JV is BIOS and GD25B127D is EC ROM. Right? Could I in principle program the ROM submitted for OP or is that a no no?
