[Firmware upgrade during initial setup not working]

Wow, the problem was solved pretty easily now. I was stupid and accidentally tried to install NANO updates all the time and didn't double-check. :-)

However, it looks like my Pineapple started into recovery mode automatically. But after the upgrade (with the now correct firmware), I came to the initial setup GUI.

Thanks a lot for your help and quick response.

[Firmware upgrade during initial setup not working]

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?
