Unofficial builds for Sony Xperia devices

Sorry but doing this would be low down my list of priorities.

AFAIK my builds can all be installed and updated successfully using adb sideload. If Local update doesn’t work, that

  1. may be related to the issue (reported by you) mentioned here
  1. may get fixed if / when OTA updates are implemented

That is ok, no problem. I thought you and rik are building similarly the images so it seemed a bit strange to have different behavior.. but I understand very well the low priority reason.
When/if OTA updates will be implemented the importance of Local updates will be reduced a lot (my opinion!).
I can live just fine without Local updates or OTAs.
Have a good/productive day!
