So I was messing around and deleted the market app (called Play Store). I changed it to a user app, which screwed it up so I uninstalled it. How can I reinstall it. I downloaded the .apk but don't have a file manager installed. I tried to factory reset the phone but that did not work. What next? Would de-activating it and re-activating help. Do I need to flash it. How do I do that. UPDATE: so I found the Android system recovery using simultaneous Home button, down volume and power on, from an off state. I did the wipe partition, factory reset, and reboot but nothing changed. I made the Play Store a user app before deleting it. I can reinstall it from the .apk but it still does not work. What should I try next.
