My Sensation 4G is on Android 4.03, Sense 3.6, software rev 3.32.401.5 I rooted it long ago in order to install Titanium backup. A few weeks ago the backups started to fail because root privilege couldn't be obtained. I haven't had time to investigate this yet. Today I realized that the periodic OS software update alerts and subsequent installations I'm getting aren't actually doing anything. If I check for an update right after installing one it wants to do it all over again. Apart from backups not working and the phone not updating it's working ok. Any ideas?
