There have been a number of users reported that after the recent 200MB OTA update, their A890 is now stuck at TeamWin recovery. The reason is their ROM is SphinX, and rooted. Therefore, for any devices (not only A890), if you are running a custom ROM with rooted, please do not update your device via OTA.
