| Error Message | Solution | |---------------|----------| | "Bootloader password protected" | Some v3 units have a secondary bootloader password. Try 7004t_default or contact your vendor with the serial number. | | "No console output" | Check baud rate – try 9600, 19200, 38400, 115200. Also verify your cable is a (crossover) cable, not straight-through. | | "MTD partition not found" | You interrupted the boot too late. Reboot and press the key earlier. Alternatively, the flash memory is corrupted; use fsck from the bootloader. | | "Command not allowed in secure mode" | Some v3 units enter secure mode if the watchdog timer triggers. Power cycle completely (disconnect both power inputs) and retry. | Check System Date: | Error Message | Solution
