Exactly same issue with my ATV380 - given the system seems to be close to retirement I did not bother trying to reset the box. It is currently looking like bricked since it does not boot anymore (stuck on the Mygica logo for ages) I decided to go with a slightly beefier alternative from a brand doing graphic cards
Will try whenever a new version is released for the ATV380 but for now it is a beta and not as stable as one would like for that kind of device
I was just wondering if I forgot to do something.
Your statement that Android 6 is never going to be available is what I was looking for. The lifecycle of these is quite short.
I installed this on an ATV380 two weeks ago now.
Kodi's GUI is responsive but playback is inconsistent - it either lags and/or skips and/or freezes for a few seconds 3 to 5. I have that on movies on remote CIFS, streams for an HDhomerun box on the same LAN which has been working fine for a long time and other sources as well. There is no issue with these sources on a traditional PC running Kodi.
It is not unusable but it feels like something, somewhere is under specs for Kodi 17 as a player.
Netflix works fine so as youtube.
I was wondering what is missing for you to release this and whether 5.5.1 will be the last release or whether a 6.0 could work.
Anything I should do to help troubleshoot?
