Hi all, i've been going this forum long enough to try and root a tv box that i buyed recently, but this one is HEAVILY locked up, like nothing i have seen before.
My objective here is to access 'su' so i can have access to rooting/overclocking this thing for emulators, and after that adding a heatsink, active cooling, etc.
I tried ADB over all USBs (4 in total) but nothing. then i tried to see if root was available through some leftover app or vulnerability, but nothing.
Then i tried following the specs from this thread (pretty similar in design to my PCB) but my UART displays nothing. (I leave the images from my setup below), i tried switching the wires, i tested the voltages and they return 3.3v, so they are ok.
I tried the toothpick method to access recovery, but it has 2 buttons. 1 does nothing (AFAIK) and the other one goes directly to updating, so no menu.
Any help is appreciated, as i'm out of any ideas.
I leave my pictures below, and my specs:
CPU: Alwinner H313
RAM: 1GB
ROM: 8GB
PCB: Z01S-v13.3, 2025.05.20
OS: Android 7-8 ish
