Tutorial as it is now is pretty much useless. Since i was one of those that screwed up the board because there are still 864 bios files linked on the forum for the 864s.
Could you please make some more pictures that CLEARLY indicate wich cable goes where from the programmer to the 864s board?

Take 3-4 clear pics where people can understand where to connect each cable please.

I have a CH341A controller and a bricked board on my table but i really do not know where to plug each cable.

On the board i have.


But on the programmer i have only few of them

Wich ones are necessary and how should i connect them to a CH341A programmer like the one in link (i already know i have to use 25Cxx but do not know where all the cables go.

this is the programmer https://www.amazon.it/KeeYees-SOIC8-EEP ... 003&sr=8-1

Since this looks like the only one that can be easily found in Europe, it would be of great help to make a tutorial for this.

I tried to get my LP alpha 864s auto booting and it stopped booting altogether. I think your BIOS files are all mislabeled. I re-flashed BIOS and it was booting again and when I tried to update to the auto booting a second time the LP stopped outputting HDMI and wont power via USB C anymore, only thru the DC pins. reflashing the BIOS no longer seems to work. Any idea how to fix this?
