An error came while i was updating my v10 tmobile.

[AC Question]

As I pressed install and restart the device restarted and a file was booting suddenly half way there it showed an error sign and the phone froze. I took out the battery and turned it on. Now It's saying that I'm on latest android version but the software version is still 5.1.1. The download file isn't appearing again in case I repeat the download process.
