Phone is unable to download and install latest build

[Prathameshk]

My L1320 is not able to download the build...
Today morning I downloaded the build but after 91% it directly redirected to the preparation of installation the download was not completed properly and preparing for install stuck at 76% after that my phone rebooted...again I tried that but same problem this time too...so I checked my storage sense settings I found that my phone storage is showing that it is encrypted...i think the problem is with the internal storage...i think I need to hard reset my phone...
Any idea how to solve the problem (w/o hard reset)

Just hard reset it and try again. Without encryption.
