Default HP EliteBook 865 G9 - BIOS issue decrypt

My HP EliteBook 865 G9 notebook was accidentally encrypted and could not enter the BIOS. It is relatively new. I extracted the data of the front and back memory of the motherboard: 6050A3334301-MB-AX1. I hope someone can help me.

try. Leave EC intact and write this in Main_Bios (Memory_01).
it will enter in MPM mode, press F10 and you have a tab under "Main" named " set machine unique data" and you'll find all data on stickers of back of the bottom cover. to exit MPM mode use BCU 4.0 under windows or restart laptop how many times counter shows.

The HP screen is very slow after powering on, a few minutes.

Turn on the black screen, the fan runs wildly, and HP icon and red letter appear after 1 minute. How to clean ME; There is only red ink and no warning when the machine is turned on. It only needs to read the IC content next to the memory, and it still needs 2 IC contents.

Clear the IC and write the firmware. The computer does not respond when it is turned on. The caps lelock and numlk indicators flash 6 times, and the charging indicator flashes; When the machine is restarted after forced shutdown, the power indicator lights up once, the caps lelock and numlk indicator lights up for a long time, the power indicator lights up twice, and the charging indicator lights up; Then press the start button to cycle.

No way, check your procedure again, did you accidentally lose any components around the bios chip?

since you can enter in bios setup it means you have no password. Load factory defaults (doooh! it is obvious!) and "change admin password" will disappear. Set machine data as I told you, exit MPM mode as I told you and "red ink" will disappear. I see from your photo you didn't set correctly data, Product Name is HP EliteBook 865 G9 Notebook PC, expand "show Advanced..." and don't blur it because ALL DMI are in bios content you post it here.

After rewriting the firmware, you can start the computer. Now the problem is that the HP screen appears for too long, and all the contents are filled in. It is observed that the keyboard light needs to light up twice before the HP screen appears after pressing the power key. The first time is that the caps lock and numlk flash six times, and the second time is that the HP screen appears.

I checked my BIOS file and found that it was the engineering BIOS (U82 Ver. 80.13.00), not the official BIOS (U82 Ver. 01.03.01), so there was a startup exception. I couldn't upgrade the BIOS (prompt: BIOS update did not occur because the system administrator has locked the BIOS version). I uploaded the latest official BIOS

Back up the files that can't be turned on. Is it different from the original file?

If there is red ink, it may be necessary to rewrite DMI information. What should I do? Can you share your method of changing BIOS? I also want to learn.
