Hello
Sprint models do not have security in EFS.
For no service most possible fix is use 786 reset make sure no FRP/RLOCK is active.
Second unlock with diag port selected to make sure LTE and network configuration is updated.
Three write QCN and repair existing MEID with gcpro over uart.

If after all 3 steps you still failed to reach network most possible your imei is blacklisted or you have modem mismatch or hardware issue.

Sorry not to mention that this J320P from Virgin Mobile. Which also belong to Sprint

IMEI is clean. I think the phone's QCN is not work with GSM.

I still look for QCN for Sprint J320P to see if the phone pickup signal
