[Problem] HP EliteOne 800 G3 AIO stopped working

BIOS/UEFI Modding BIOS Modding Guides and Problems
1

I have a HP EliteOne 800 g3 aio, out of nowhere it stopped working and blinking 6 red and 3 white (the same problem here) and everything didn’t work.
I deduced that it was a BIOS problem, my mb has 2 SPI chips: 1.MX 25L12873F and 2. MX 25L647F. I have ch341b programmer and desoldered chips and read here.
(btw when the chip is desoldered, the mb reports the same error 6.3).

I don’t know what to do because hp oficial bios driver is only for an upgrade and not a full bios. Can someone tell me how to fix the bios or where is the problem?

Have you tried this, full drain ?

Volumes seems valid, you may re-initialize the CSME v11 fw engine, according the guide.

I tried both options and nothing worked, still 6.3

I have update, I noticed that from the bottom of the board there is a missing resistor , i sloder a wire instead of resistor and fan is spinning , temperature of gpu is Increasing , but monitor is black(With an old working bios). I have 2. options:

  1. Try to upload a new bios file with new ME
  2. Go to repair shop

But idk why is black screen i “fixed” Fault with resistor and old bios file should be functional.
