I was having some trouble with my rooted Samsung GS3, so I "tried" to perform a reset by flashing a stock ROM in ODIN. Once I booted it back up, the first thing I saw was "Unfortunantly, the process android.process.media has stopped." I thought that was weird but continued with the setup process, but it kept happening frequently. Media, gapps, Play Store, gallery, contacts and others were "unfortunately stopping". I can't open the play store, camera, phone app, contacts and some others. Now, I use only the messaging, Internet, and Youtube apps. I can't download any apps, or anything really. I've tried to reflash the ROM with ODIN, but that does nothing. I've flashed CWM to it but that doesn't even working properly. I tried to restore a backup I have on my External SD but when I hit restore in CWM it just says "Couldn't open directory. No files found." Device is SGH-I747. I'm going insane with this. Please help, any response is appreciated.
