Xperia Z5 Auto Farctory Reset itself

[tncalucard]

Hi,

I have a Z5 for about 2 weeks and it has been doing factory resets on its own about 5 times.

The worst part is that it delete the content of my SD card also.

I already done what was recomended on both links bellow and tThat didn't solve it:

/t5/Xperia-Z5-Z5-Compact-Z5-Premium/Z5-compact-rebooting-itself/td-p/1047396

/t5/Xperia-Z5-Z5-Compact-Z5-Premium/Xperia-Z5-Premium-Reboot-itself/td-p/1066833

I also have disabled the MyXperia functionalities and I use a two steps authentication for my Google account what makes almost impossible to have someone reseting it through any of these methods unless it is me.

Does Sony has a solution for that?

Sorry to hear that.

First make sure that you haven't switched to another account by accident. On the lock screen, swipe down the notification bar, tap top right icon and select the owner account.

If that's not the cause, do you have any corporate account in your phone like an Exchange ActiveSync account?

Hi,

I don't have any other accounts on my cell phone.

My phone was on my pocket and when I took it to look it was doing the factory refactor.

You need another motherboard.

So,

If I take to my local support they should do it?

Does anyone has access to your Gmail's password? 

[tncalucard]

No @uliwooly,

And as stated before, I use 2 step authentication so they would have to have access to a trusted machine (impossible) or have my phone.

Best regards.

That's rather odd, but do contact your Local support to get your device inspected

But you don't have any account or app that enforces a PIN pr password on the phone? These may also reset the phone if you enter wrong PIN/password X amount of times.

The first time it happened I did not had any, but now I am using one. 

I will test later if that was the case. 

Still it would be rather strange as it would require me inserting the wrong password an amount of time. 

Best regards
