  • Do not turn off the device
  • During LTE Modem firmware flash normal functionality of the Teltonika Networks device will be impaired:
    • No Mobile Data connection, SMS, call functions;
    • Possible WebUI issues;
  • If update has failed, LTE Modem firmware download and reflash procedure will start again at next power cycle for RUTOS, and on network / modem restart for Legacy firmware devices.
