My brand new M4 (dual sim) keeps resetting. I got it on Saturday and when I started it and worked with it for a few minutes it already restarted (screen turns black, starts with Sony/Xperia logos, then purple screen before it opens again, then you need to unlock the sim card again). Sometimes it runs fine for 1-2 hours, sometimes just minutes.

On that same first day, when I was at the home screen, it just stopped doing anything. You kept seeing the home screen, the time stood stil, no button was working (no reset possible). The only option was to wait till the battery ran out (the screen stayed on, so this happened during the night). Today, an hour ago, it restarted and now it is stuck in the purlpe screen after Sony/Xperia logos. No button works, no reset possible, the screen stays on. The only thing to do is wait till the battery runs out again.

I already tried going back to factory settings, that didn't help either.

My questions are, does this happen more often with Sony . And secondly, where do I need to go for support, Sony Netherlands or the webshop (Pixmania)?

I hope they can fix it quickly, I ordered this M4 Aqua because my iPhone stopped working because of water damage. I used iPhones for the last 6 years but wanted to try the water resistant M4 Aqua.

All replies and tips are welcome!

Are you using the correct SIM card size? or did you cut/trimmed it?

you could repair the phone with PCC and report back if it works

PC Companion (PCC)

Bridge (for Mac)

Yes, I do use an original nano sim card (Vodafone NL, that worked fine in my iPhone 5).

I will try the Bridge for Mac. But unfortunately I have to wait till the battery runs out since it is in a loop now.

@UvB

Do you experience the same loop without the SIM and SD cards?

UvB

I tried without the SD card before, that doesn't change the situation.

I now removed the SIM as well, but it stays in the loop, so I have to wait till the battery runs out...

UvB

I got it out of the loop now.

But also without SIM, without SD, it keeps rebooting (already twice in the last few minutes).

@UvB

Let us know if you can repair it with PCC, if not, you will have to contact your local Xperia Care

I opened the bridge for Mac. I'm trying to repair. I'll post if it works.

No, unfortunately it didn't work...

I did a full repair cycle, new software, fully fresh install.

Already during the first setup dureing step 4/7 after the wifi, when you setup the google account, the M4 started rebooting again.... To be sure, I started it with no SIM and no SD.

So probably a hardware issue? Does that happen more often with Sony M4's?
