I'm here trying to resurrect my Razr x912... First it begans to show a ? in battery icon, and do not accept any charge. I've used it until it discharge completely... I changed the battery, but now it is showing 100% charged when plugged on charger and when I unplug it and attempt to boot, nothing happens... I don't know if it is the right place to question that, but any help will be appreciated... Thanks!
