My tablet http://www.amazon.com/iDeaUSA®-Andr...1&redirect=true&ref_=oh_aui_search_detailpage is stuck in a loop on boot. First the company's logo comes up, then the android screen, and then that just stays on screen until the power dies. Any ideas on how to fix this, whether restoring it back to how it shipped or rooting and installing something else on it?
