Sonicpoints stuck at rebooting state even after firmware upgrade and hard reset

SonicPoint stuck at rebooting state even after firmware upgrade and hard reset: TSR (Tech Support Report) showing reboot reason as Reason Code 1 which is triggered by the normal provisioning procedures.

It can be due to corruption in settings (NAT policies).

1. First check the steps as per SonicPoint continuously rebooting or stuck at initializing
   
2. If still SonicPoint is rebooting, then it's due to settings corruption which causing SonicPoint not to SYNC.
3. Look for Nat policies which are using M0 IP (U0/U1/M0 are External 3G/Modem Interface).
   

   NOTE: M0 IP is extension module which acts as an extended port for the SonicWall.

4. Delete the Nat polices which using M0 IP.

After deleting NAT policies, now SonicPoint will start syncing and will be showing as operational.
