I need to update my FMC130 (~ 20 devices) to the last Firmware version 03.27.13.Rev.54. Actually they all have the version 03.25.10.Rev.162 .
I always get the message "Too many attempts". I tried multiple time with different devices but it's always the same.
I was in contact with somebody of the sale from Teltonika who was able to update 2 devices but the person didn't told me how to do, and now says the ticket for the engineer has been closed and I need to write here...
Seems the person made first an update to 03.27.07.Rev.00 and also changed the config. I tried but wasn't able to make it work.
