Re: [Sprint Only]UnRoot and Return to stock
Update: I was able to correct this issue by performing a battery pull while stuck in the Samsung boot screen, entering the stock recovery mode (instructions below found after some research) and performing a factory reset. Works like a charm now!
If stuck at the booting animation/Samsung logo, perform the following steps to make it boot. Remember that these steps will wipe your personal data like contacts, apps, messages, etc
Boot to recovery mode — for which, first power off phone (by removing battery and reinserting it), wait for 5-6 seconds, and then press and hold Home + Volume Up + Power keys together till the screen turns on, then let them go to boot into recovery. Once you are in recovery mode, use volume keys to move the selection up and down and home/power key to select the option.
Go to Wipe data/Factory Reset and select it. Select Yes on next screen.
Then, select reboot system now to reboot the phone, which will now boot properly.
