Hello. Looks RUTX series has some issues with modem upgrade via GUI.
After upgrading to 7.4.5 (RUTXR1) I tried to update modem firmware from GUI, and it does nothing in the end. Just shows banner “Modem update is in progress… Do not power off the device.” for a very long time. Nothing interesting was shown in logread output.
Correction: Web update works, but sometimes it just fails.
After that I run from ssh: dfota -u
This command actually connects to modem’s vendor server, download and install correct firmware.
Surprise for me was multi step upgrade, from
EG06ELAR04A04M4G > EG06ELAR04A07M4G > EG06ELAR04A08M4G > EG06ELAR04A20M4G
So, is such path mandatory, or I may somehow skip to latest version? And how to find, what is latest version?
P.S. every time duering “dfota -u” execution, i had following error:
[get_tap_info:135] error: Failed to load ‘device_management’ package
Is it modem’s vendor issue or Teltonika’s ?
