Factory Reset

[Newellus]

Hello,

how can I make a factory reset by my m4 aqua? I've lost the screenlock pin and a reset via PC Companion does not work.

Can somebody help me.

Thanks.

Is there no way to reset the phone? Can somebody help me at a local sony store?

Hi @Newellus, sorry to hear about this and I apologize for the late reply.

PC Companion was discontinued a few years back and was replaced by Xperia Companion. Have you tried to perform a software repair using Xperia Companion?

Make sure that the device is powered off and not connected to the computer when you start with the repair and after clicking on "Software repair", check the little box in the bottom left corner to proceed.

Let me know if that helps!

Hi Jonas,

thank you for your answer.

Yes, I've alread tried xperia companion, but the phone is a few years old and I cant find the google account which is refered to the device. So I stuck on the step where I get asked for the google account.

Hi again @Newellus!

Oh, I see.

On the Sony Xperia M4 Aqua there is an anti theft feature called MyXperia theft protection that gets activated when you set a screen lock on the device and have a Google account added. That is why you need your Google credentials to be able to use the device after a reset.

This protection can't be reset on your own, so in your case, please get in touch with your Local support team and they will advice you how to proceed with this, as the device has to be sent to an authorized service centre.

I hope that helps!

I 've ignored the message that I can't access the phone after reseting anymore when I've no google credentials but now it worked.

Thank you

regards, Newellus
