Device stuck in a "bootloop". Resolved after re-inserting battery A Customer of mine has a Casio V-T500 Tablet on which he runs our app. For a few days it started to be stuck in a bootloop which could be broken by removing the battery, wait a few seconds, and then putting the battery back and starting the device. It's running Android 4.0.4 with an special Launcher by Casio.  

Does someone ever have/had this kind of problem? How can this be resolved? Is this a hardware failure? After about 9 Months of "work"?
I got stuck in a similar bootloop last Sunday on my Samsung GS4 (i9505G), except instead of rebooting, it would power off.  Pulling the battery did not resolve it.  I had to plug it in to a charger.  The battery was at about 25% at the time.

Sadly, I do not know why that resolved the problem, but I wanted to post my reply in case it helps someone.
