Screen is out. USB power is out. Battery power is available only through jamming in my old LG Leon battery the right way - which has been repeatable three out of twenty times. When done so and it's on, USB file access is possible through My Computer, and I've manually grabbed everything that shows up. However, that accounts for only 399mb (most of that being pictures and video; most of the folders and subfolders are empty as well), and it says 3gb of space is taken up (note images attached). What could be missing, do I need to get at it to make my new phone just like my old one, and if so how?
