Pls help, I think I breacked my tv box When trying some rom, I tried to flash any rom with amlogic burning tool its stopped at 7% then I burn android image on SD card now I could burn up to 8% with burning tool while the SD card inside the device is there any command through UART or any procedure to install android system again, attached the putty log file and the USB burning tool log file.
also I read about file named (SECURE_BOOT_SET) in some chines site and they used it in USB burning tool is it useful i try to put it at the path witch they mentioned but it doesn't show up in application window
notes
