Hello friend!

B660 is a Consumer product. Check whether the power supply is normal.

If the device restarts repeatedly, the device hardware may be faulty. Remove the SIM card and reload the SIM card, then connect the power supply to check whether the device recovers.

If the fault persists after the device is restarted, contact the device provider for assistance.

Thanks!
