So I rooted my 10' sylvania tablet, and i started deleting things i obviously shouldnt have. It was stuff like phone.apk and the like. It ran after i did it, but then i decided to reboot, and now its stuck in a loop and wont go past the loading screen. Has anyone successfully done a factory reset? I have a usb cable but i cant install the drivers. I assume its because i have windows 7 64bit. I honestly dont know anyone that has any different systems so that could be a problem. I have an SD card in the mail if that helps. I also backed up all the files i deleted beforehand.
