As an anecdote, and looking through the posts looking for information, I have been able to see a model similar to mine; an HP Elite x360, which is not the same board but has the same system: (2 chips exactly the same as mine, and from what I have seen the lower one is the EC chip and the upper one is the main one), I add a screenshot that I found, based on that could it be built having the softpaq downloaded from the official HP website (which I have already uploaded here in a post) and separate it and create the main BIOS part and the EC part? Let's see if someone can give me some more info,...

Hi m1ch43lzm, thanks for writing.
I've always done dumps and recordings by completely removing the motherboard from the computer, without the battery, CMOS battery, SSD, or Wi-Fi card. The reason the motherboard LED lights up is the programmer itself. Both the "CH341a" and the RT809HSE do this (not the battery or when connected to power). They do this when they power the chip during detection or reading/flashing. It can be seen that the 3.3 volts make the board have enough voltage to try to turn on when reading the chip on the board itself, that's why I did the reading with the...

Well, while I waited for news, I ran more tests and nothing. Thanks for the SMDflea file, but it didn't work. With that file, when I plugged in the computer, the motherboard's LED flashes yellow continuously, but it doesn't boot...
Now that I'm done, I've run every test I can. erasing the other chip, leaving it empty, and nothing, the computer does not start, I have noticed that every time I flash any file, the verification always gives me an error, so I do not know what it can be, if some kind of protection or if the two chips are intercommunicated and while you erase one the other is erased...

Thank you so much for your help, your time, and for helping me, SMDflea. I really appreciate it. I know I still have a lot to learn and test, and I'm working on it, but I still have a long way to go, so thank you all.
One thing: thanks for the file you offered me, but before testing it, I wanted to tell you:
With so many tests, I think I've also corrupted the other lower chip (the one similar to the SKT BIOS -> W25Q256JVEN), and I don't know if I should flash it and set everything to 00 or FF, or if I should flash some file on it. I'm also not sure if they both work together at...

Well I don't know if anyone is reviewing my problem, I'm not an expert but I see that it's a problem with the ME Region firmware of my dump that must be corrupt because I flashed above the chip without having a good backup of the chip, I tried to clean the ME region (being a bit lost) in the instructions here in a post I found in the forum and from the dump I used, I used: CSME System Tools v13.50 r3 and CSME 13.50 Repository r7, and through flash image tool, I replaced ME sub partition with my corresponding file which is: CSE ME 13.50.27.1987 Prod Atom N and finally I built the image, I flashed...

Well, I managed to get the computer to boot with the attached file, but it takes a very long time for the BIOS to boot, and it takes a very long time until Windows appears. There's a problem with the BIOS, because I tried updating the BIOS downloaded from the HP website once in Windows, and I got a firmware update error message: "Update of the Intel management engine firmware failed, because the target Intel management engine firmware update was found to be invalid." (screenshots attached).
Am I missing something in the file I flashed?
In that case, is there anything I can...
