Ok this just happened around 15 minutes ago. I am running version 5.0.328
I was going into my text messages and when i clicked the icon it said "uncaught exception..." I then did a battery pull and it was loading up and i get a white screen saying "JUM Error 102 Reset" so i did another battery pull and same screen.
Ive never had a problem with this phone then this happened.
i had a jvm 523 error with a white screen i called verizon and they told me to pull the battery out and hold the end call button for ten seconds and then put the battery back in. I did that a couple of times and it did not work at first, then while it was restarting I tried pressing the end call button and lock button about five times each while it was restarting and it came back working as normal
