My phone got locked after doing a factory reset and now I am not able to use it. I tried logging in my valid google account credentials but the device failed to authenticate it.
I already reset my phone using PC Companion and it gave me fresh start screen similar to when I got the phone the first time where I have to select the default language, but after few seconds the black window that requires Xperia protection authentication appeared again. And it still cannot authenticate the logins!
What should I do now???
