Description

I have a router 4G cpe modem with linux embedded without web access and terminal does anyone know how to recover? I checked on the board has the points RX, TX, DLOAD, RESET_N, so I saw here only have SMD components so the only way to rewrite the firmware would be for these communication points. Note: I tried access via serial but stops at bootloader.
