Hello jock, Thank you for your guidance and for clarifying that my device isn't truly hard-bricked. Regarding your question about the firmware, I used the image from this link: https://mega.nz/folder/v2IEEJqK#WR2o_RwAvS0XWd3pBmnp7Q. Could you please advise on the next steps, or if there is a specific way to use the UART adapter to diagnose or recover the device based on this specific firmware? Thank you for your help Sorry if I ask a lot of questions because I'm a beginner.

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!
