My 'droid X has been restarting after shutdown. It's stock, not rooted, Sys version 4.5.605.MB810.Verizon.en.US, Android version 2.3.3. I recently updated it (I do that whenever notified), and now it wants to restart after I tell it to shut down. I press the power button, get the shutdown/airline mode etc/ menu, and tell it to power off, and it does. Six minutes later (roughly), I get the powered on tone. Shutting down a second time usually works.
Wifi and Bluetooth and GPS are off. I have very few apps -- most of what's running are bloatware things from V. I do have a app killer (Adv Task Killer Free), but it doesn't autorun. I have tried using it to shut down all apps prior to power off, but that hasn't helped.
This only started after the latest update.
