Hi there!
as there were some the problems with iodeOS upgrade 7.0 I decided to wait for version 7.1. Now I´m still on version 6.9 which was no problem at all to upgrade from 6.8.
After following the instructions for the upgrade procedure I first updated the updater, which seemed to work. Now: when starting the upgrade, it stops immediately and saying “The download failed please check internet connection…”
just to clearify: I did download the ota file and installed the update locally. And for that action I used the original updater. The install function directly in the Updater app did not work.
Downloaded the 7.1 from GitHub to my Brax 3 with Wi-Fi only. Downloaded and installed fine. Had to send the link from my other Bracks 3 so that I could update it.
