Hi, do you have the diagram to show where to solder the pinout for reprogramming the EC? I reprogrammed the BIOS but it won't turn on anymore. I want to know the programmer I'm using for EC, it's XZZ.

pinout for this one unfortunately unavailable

i don't know about XZZ programmer
but SVOD programmer you can program EC files

Lamentablemente, el pinout para este no está disponible

No sé nada sobre el programador XZZ
pero el programador SVOD puede programar archivos EC

Voy a leer documentación; vi una guía en Reddit que alguien usó, y si pudieras ayudarme, sería genial. Si no, leeré diagramas y documentación.

I performed the procedure with the programmer and it worked perfectly. It flashed super fast. You can flash the BIOS and EC without disassembling them, just by connecting it to the battery terminals. Later I'll upload the whole procedure and tell you where it should be connected.
