For a couple of months now I have been prompted to upgrade my OS from IMM76L to JZO54M and each time that I try it restarts the devce and begins the update, however, the progress bar gets about 1/3 of the way and stops. After a few minutes I'm left with the screen showing Android lying on his back with an exclamation point inside of a triangle. Can't be a good thing, and it wasn't.
Upon restarting, my tablet is left with the old OS. I've even performed a factory reset and tried the update with the same results. Any help would be appreciated, otherwise, it might just be time to retire this old device for a yet to be determined replacement. It's sad to have waited this long for the update only to have it fail time after time again. Also, the only updates that this device has ever taken are the OTA updates supplied by Verizon.
