i have update my blackberry z10 to 10.2.1.3062 after 12 hrs my open get hanged and i took out the battery and now its not turning on & there is no display
All my years using BlackBerry I've tried to stay ahead of the curve, and rule my own destiny. Something about the risk of an OTA upgrade has always set me uneasy, and I've never been with a carrier that released "the latest" first, but one rare occasion. Even if they did, I'd do a backup first, because OTA while typically smooth, comes with risk. No backup as prepared defense from disaster, and you're just taking a chance at failure of immense proportion. I prefer to prepare for the worst, and test out a leak I can roll back from, than think I'm playing it safe with my carrier, only to have them lead me from the pan, and into the fire.
Of course I'm that fool that beta tested alpha hybrid OS on BBOS for years. I learned to be ready and solve damn near anything.
