I connected the SIM7600E to my WIN 10 laptop, which has the appropriate port, to update the firmware from LE11B08SIM7600M22 to LE11B14SIM7600M22. Installed the drivers. I used the utility “sim7080_sim7500_sim7600_sim7900_sim8200 qdl v1.67 only for update”. At the moment of 1.27% it gave the error “waiting for dut,long time please repower dut…”. The modem is no longer detected and does not work. What should I do? Help him revive.
