Hi @lapulga507

What kind of module are you using? Please download the latest firmware to the module and retry.

It works well on EM7455 firmware SWI9X30C_02.33.03.00.

Hi @lapulga507

Please download the latest Generic SWI9X50C_01.14.02.00 firmware to the EM7565 module and retry.

You can get it here AirPrime EM75xx Approved FW Packages

It is OK on Generic SWI9X50C_01.14.02.00 EM7565 firmware.

is it possible to flash the MODEM when the modem is connected to a router running OpenWRT/Rooter Firmware? can you share some steps by steps instructions.

Thanks.

You’ll need an openwrt device with enough ram to hold the new firmware.

I couldn’t complete the update with the link and instruction you posted early, however I did follow the FOTA instructions and it did work fine and also fixed the problem.

Thanks.
