Anyone knows a good backup app for unrooted users?
When the update fails, press both the volume up and volume down keys at same time. The last few lines of text tell you what file is causing the update to fail. It will probably either be an APK or ODEX file that is being identified.
Then, just find the file from one of the droid file dumps on the site here and replace that file on your phone.
I have 4 files that were not right for some reason.
So my weekends are so busy I haven't had time to mess with this especially since it kept failing and I'd have to redownload the update. First off I figured out where it stores the update files so I can save a copy on the sdcard which make retrying the update less painful. Second, thanks to daryls61's post regarding viewing the verbose aspect of the installation and seeing where it's failing I'm one step closer to getting this resolved. My guess is that it's the apps I've frozen with Titanium.
