So, I was given a MyTouch Slide from someone... in other words, unknown and sketchy origins... the battery is testing good, but it's deader than a doorknob. Won't turn on, won't hard reset... nothing lights up. No water damage, physically looks fine. Seems just plain frozen. Any ideas? Think it's worth sending off to Doctor Cell Phone or somewhere else for diagnostics? Anyone have a great repair/diagnostic place they have used and want to share? All feedback and ideas appreciated.
