I had to do a Low Level Reset on my A3 this weekend, it locked up and I couldn't get it to reboot or finish a cache and data erase. I wiped and restored to ver .60 but could not get any automatic updates to work. I loaded .78 from the Amiko Dropbox link in this forum and restored from an earlier backup (the Amiko Americas A3 backup loaded right up). I was able to get the Advanced Sat Installation app too. The FDroid app appears useless now; isn't that just a server holding "favored" apps for download? Anyway, it seems like our support options are limited to the files and instructions we have documented here.
Don't get me wrong. I still prefer the A3 and it is my main FTA box. I find it excruciating to swing the BUD with another receiver because the A3 will stop itself when it hits the signal. That is enough for me to deal with the occasional reset when it locks up. really, the restore only takes a matter of minutes now that I have the sd card standing by ready to go.
