Unpaired Galaxy Tab 2 10.1 (GT-P5113 WiFi only)

Last June I installed Anti-theft on my girlfriends Tab 2… She managed to delete it in her My Avast account. I certainly can’t enter her PIN as a phone number to get into the Anti-Theft app… How do I get into the program? And once, (if), I get in, how do I go about re-pairing her device to her My Avast account?? Help please… Thanks

Today I experimenting in changing avast account in Anti-Theft.
I removed my device from account on my.avast.com, and then realized that I couldn’t open program inteface.
I remember pin-code, but my device can’t make calls like cell phone (it is simple tablet).
But I was able to uninstall the program. Luckily the device has not been rebooted.

Try uninstall Anti-Theft from PlayMarket and install it again.
