My LG has also been having these "bootloop" shenanigans, and it's driving me crazy! I did nothing with my phone, actually it's almost brand new, and out of nowhere, BOOM-black screen, LG logo, Blue start up and then..repeat ad nauseum..I just tried removing the battery for ten minutes, and so far, it hasn't helped. Really sick of factory resets-at the moment, I've done two..and tomorrow I'm probably exchanging this for a brand new phone per my two year insurance..I currently use Straight-Talk. I never had these issues with any other phone, and I wonder if this is due to an app ?? possibly leaving crapware on the phone somewhere? Is that possible?? I thought that phones were sort of "protected" from virus issues more than pc? anyway, this is horrible. thank you all for posting all the info that you have, it's helped me so much in the past to learn how to fix my own issues instead of asking my uber tech brother. so far, still looping. so battery removal didn't do anything. I'm curious about the possibility of an app doing this, as i've had quite a few I installed and uninstalled..(I always clear cache etc,before deleting..) anyone ever hear of an app doing this kind of thing? thanks.
