Changed the sim card. When I putted the new sim card it says devices stole/lost, require unlock password. Typed the password couple of times then went to different device to reset the password but still not working. AVG Ant-Theft

Does this method still work if your moblie phones wifi is offline?

let me change lock code via web.
did not update lock code on device. still locked out.

Thanks all the members for shraring useful info here.

For those who have the same problem I had. This is simple, just log on your AVG account on different device, as long as you remember your email address. It will show you lock option on the tools bar, press lock, you'll get option to choose lock pin/password then enter and confirm. Then now you'll will have unlock option on the tools bar, enter the same password, your device will be unlock…walala wasala…easy as that. I don't know why some answers complicate this.

my problem as well coz  wifi needs to be onnected and i cant as well since the phone is locked

i tried this and it is still asking for a privacy protection password, dont know what else to do

My story is smilar to the one of Miguel. My tab is locked, I have reset the password on the different device but still I can't log in on my tab. On the answer from AVG is not clear to me. My wi-fi its on and still I can't unlock password.
