I'm trying to install open solo 4 on my system. Firmware hasn't been updated since 3DR days, but was up-to-date when I packed the system away 4 years ago. I recently purchased Solex, and would like to upgrade firmware. Solex and My system have worked ok for 4 trial flights. I'm following the instructions in the forum to upgrade the firmware, but when I try to download the open solo zip files my Samsung s10e (android v11) displays d!= java.lang.string for a couple of seconds and nothing happens (I've waited 20 minutes and nothing happens using my home wifi connection).
Any advice?
