Hi guys, I beg of you to help me!
I have changed sim card while on vacation, and avast antitheft got activated, now it does this every time because I travel alot, but this time it was locked and no matter what pin code I type it would not accept it! I am 100 % sure about the pin.
I tried to unlock the phone from the website, but commands were not going through, not the change pin, or the unlocking. I became so frustrated that I deleted the device from the control panel of the website.
Now my phone is locked, I cannot use it and no matter how many times I try, it does not accept the pin code, and the time interval betwee attempts keep increasing!!! Some one please help! how do I delete this antitheft?? or can I get my pin code sent to the contact number? or to my email address?? please please!
