C5 Ultra My Xperia Protection unable to Authenticate valid Google account.

Russ29 — Mon, 26 Oct 2015 11:20:22 GMT

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???

Yeah I'll be bringing my phone to the service center tomorrow. According to what I have searched it's a software bug from the Xperia Protection recently experienced by M4 Aqua Users. Sony should stop this protection service for now.
