@260575155 any more details like a screenshot？

@sandeshsahu by flashing the device the device you will lost your warranty for help may be just @Solla-topee

@sandeshsahu maybe ask the technical support for a firmware update

@sandeshsahu for your hardware version: v3.8 (IN) i think both EU firmware and v3.0(IN) is not suitable for your device

what do you mean by keep dropping, is the WIFI or LTE connection? or unstable LTE download speed?

@arun7129 for your model MR600(IN) V5.8, i think you are already on the latest firmware you got this error because the firmware you tried is for MR600(IN) V5.0
