: This is often a symptom of a corrupted firmware or a failed flashing process. The recommended recovery method is to use the UART interface (Universal Asynchronous Receiver-Transmitter). This is an advanced method that involves soldering wires to test points on the router's circuit board to access the low-level bootloader (U-Boot) via a program like PuTTY on your PC. This technique allows you to interrupt the boot process and manually reflash the firmware from scratch. Address issues with SMS, network stability, and FOTA
