The phone kept asking me to update the firmware so I decided to flash the stock firmware back on it using ODIN so that I could do so (I have read that you should never update via OTA if rooted).
When I flashed it using ODIN, upon boot up, the phone said that "Unfortunately, Touchwiz Home has stopped." I press OK but then I get another error message this time for Google Play Music (infinite loop).
I keep toggling between these two error messages, however they don't go away.
If I press the lock screen button, I can see the welcome message, the status bar etc. But soon as I swipe, the above error messages appear.
If I receive a phone call, the phone rings and goes to the answer / reject screen but I can't accept the call as the error message is in the way.
I have already tried factory reset via the recovery options boot menu, but to no avail.
I have flashed a new version of the ROM, I9505XXUFNB9 but still the same error. I then even tried rooting it again, but still the same issue.
Please help me.
