I have the original Droid razr from 2011 and i went to download the new system update i waited a few minutes for it to download and it pops up like it should asking if i wanted to install now or later. i click install now, and it shuts down starts installing and goes about 1/4th of the way and then gives me a exclamation point in a triangle, then reboots and starts up and says "System update failed". I really want the new jelly bean OS for my android. Can someone tell me what is wrong? and what i can do to fix it?
