My device is stuck in a loop doing this. Has anyone experienced similar? Have tried the latest model firmware and both stable and testing versions of the RouterOS.

Upgrading to modem firmware v28 fixed this

3

Hi. How do I get a copy of the V28 firmware?

4

to check for new version

/interface lte firmware-upgrade lte1

to download new firmware

interface lte firmware-upgrade lte1 upgrade=yes

5

This doesn’t work with v28 because you can only download v27 right now.

I had the same issue, V28 solved it, unfortunately V29 broke it again, problem appears when i download files that takes longer than about 90 seconds.
Is there any way to downgrade?
