My phone LG Volt LS740 asked me to update, so I did. And before it continued it said it will turn off and then start the new update. I agreed. Now my phone keeps powering off and on like crazy and won't stop until the battery is out. It keeps restarting for no reason. I tried hard reset and soft reset, but nothing works.
