Router Boot Loops After Update

• Solution: Perform a 30-30-30 reset (hold reset for 30 seconds with power on, keep holding while unplugging for 30 seconds, plug back in while holding for another 30 seconds). If that fails, you need a serial console recovery.

• Try a soft reset (power cycle).
• Perform a hard factory reset (hold reset button ~10s).
• Reflash firmware via recovery mode or using the router’s emergency upgrade tool if available.
• Contact ZTE support or your carrier for device-specific recovery instructions.
