I have an issue with the initial setup of my TETRA:
The connection via USB ETH works fine and I also can start the setup. But on the second step, where I'm asked to select a new firmware file to upgrade, I can select whatever firmware file I want (or even none) and it always brings me to the next page, that tells me, that the upgrade file was verified successfully and I should wait for the setup to finish. However, after about 5 seconds I'm redirected back to the file-selection page with the URL "http://172.16.42.1:1471/?cache_breaker=1473066392".
I already tried different browsers (IE, Firefox) and systems (Windows, Kali) but it's the same with all of them.
Any idea, what I'm doing wrong? Or is there a way to skip the upgrade initially and do it later?
