As mentioned in previous posts…there is no OTA method to update the OS as of today. The default Updater throws an error when it detects a higher level OS . We had a developer work on modifying this and he was able to get it working for a Samsung device. That means for one particular model of Samsung we were able to upgrade the OS by sending the ROM OTA. The development stopped at this point mainly due to lack of resource and also because further development would require detail testing on multiple devices. We were also worried about bricking user devices if this was not properly tested. For now the development has been stopped on this. Hope to get it restarted in the next couple of months. If there is any progress on this I shall put out an update here.
