I installed Android ID Changer from the Google Play Store here, https://play.google.com/store/apps/details?id=adaptive.cogid&hl=en I entered some random ID different than mine and then it restarts my device but my device will not restart. It gets stuck or hangs but doesn't really freeze at the Android Ice Cream Icon. My device is Maylong MVP-270 tablet with root access. I did make a backup using Titanium Backup Root from the Google Play Store before doing that thing with ID. I made backup of everything I think. How could I use that to restore my device when I cannot fully start device ? Any other information I will answer when I have time. I have an SD card I use on it and that's where I think the backups are from the Titanium Backup Root app. I did save my default ID before running the other app too, on memory card somewhere but I don't know how I can get it fixed. It's Android 4.0 Operating System. It's new too.
