Hello everyone,
I am trying to install Armbian on my Android TV Box, but unfortunately, I flashed an incorrect firmware. Now the device is hard-bricked: the red and blue LEDs are blinking alternately, there is no HDMI output (black screen), and the physical reset button is not working properly.
I already have an SD card loaded with the multitool to install Armbian, but I need to force the SoC into Maskrom Mode first so it can bypass the corrupted eMMC and boot from the SD card.
Device Specifications:
SoC: Rockchip RK3228A
Board ID: T39-V1.0
Storage: eMMC (BGA type)
I have attached the front and back photos of my PCB board (IMG-20260607-WA0027.jpg and IMG-20260607-WA0031.jpg) for reference.
Could anyone help me identify the exact and safe test points (CLK to GND shorting points) for this specific T39-V1.0 board layout?
Thank you so much for your help!
