We upgraded our Teltonika from 6.8.5 to 7.3.4 and everything was working fine, up until the moment we needed to switch the profile.
As soon as we switched the profile, we could only access the Teltonika from CLI, the web GUI wouldn't accept the username/password and would always show an error. We then tried to switch the profile again, using SMS. We first received a failed message. When we sent the SMS a second time, the Teltonika became unreachable.
A factory reset does not work and the unit has become "bricked".
We created a case for RMA, but we have 50+ RUT955 we want to upgrade to 7.3.4, but can't as long as the issue with profile switching remains. Anyone else experiencing this issue or know a workaround?
I saw 7.4 was released, but no mention of profile fixes.
