MXTP created problems for me.

[thebelgian]

I recently bought me the xperia M4 aqua dual and configured the Myxperia service on the device. After day 3 I restarted the M4.

As the M4 was started up the MXTP gave me the lockdown screen with the verify, wifi settings and emergency call options on it. So as I wanted to unlock my device i pressed the verify button and a log in screen for my google account appears. I use my google account on all kinds of different devices so I logged in. But here someting goes wrong.

When I typed in the username and password to verify it is my M4 it gave me a loading icon for 2 seconds and then it says "incorrect username and/or password" and my M4 stays locked. To double check if my password and username are correct i logged in to another adroid device and my laptop with no problems. So now I'm stuck with a brand new non working xperia M4 and my hope for a good working security system is all lost. 

Thanks Sony.

me too got the same problem. i bought this phone 2 weeks back. yesterday met with this problem. im able to get into the phone as a guest.. but unable to make any calls. home button doesnt work. but when i switch to owner it gets structs with "protected" interface. As im from srilanka i dont even have a sony servie center. even dont have a customer care service. helpless... very dissapointed.

Yes.. It almost bricked my phone..

But using the solution provided in this forum I was able to reset the phone into factory mode and authenticate it.

I have Unlocked My M4Aqua by following procedure..Give a Try..

MXTP is causing problems if we have more than one google accounts configured in the phone.

To solve the issue

1.Turn OFF your phone and turn it ON again.

2.Your phone will be turned on as normal before the PROTECTED screen appears you will have around 20 secs.

3.Go to Settings->Accounts->Google Accounts->Remove the Google Account which you have not configured with MXTP(except the one you used for activating Protection by my Xperia).

4.now when the PROTECTED screen appears Authenticate with the google account(given while activating MXTP).

your phone will come to normal mode...:smileyhappy:

better immediately deactivate this feature going to Settings-->Security--->Protection by my Xperia and then Decativate...
