Xperia Z2 Death Experience - Xperia Z2 Q&A, Help & Troubleshooting

Dear All,
I have been using xda for long time as a user of the huge amount of knowledge in these pages...
Thanks to this community I got the most out of my samsung Galaxy S, Galaxy SII, Galaxy SIII and LG G2.
Now I have an Xperia Z2 D6503. I've been using it for a month and I love it.
But this is my problem.
2 days ago I was using the phone normally, I checked google maps and I put the phone under charge.
An hour later, I went to check the phone, and the phone was unresponsive: black screen, impossible to turn off/restart, no sound, no apparent activity. The only sign of life is a red led when I press the power botton.
The phone is with the original stock (firmware 17.1.A.2.69), I rooted it with a guide I found here (of course) just to use an app like android firewall.
I tried to search the forum for something like this, but honestly all I could find was something similar for the Xperia Z and what was proposed there to restart the phone didn't work (power+volume up).
I also tried to restart the phone with the off button inside the slot where the sim card is. That didn't work either.
Please let me know how can I move forward. As anybody else experienced something like this?
Thanks for your support!

Try flashing official firmware with flashtool maybe? Maybe this will help, I don't know man.

---

and what about hard reboot, by maintaining power and volume up until the 3 vibrations?

I suggest you go back to stock using flashtool, use it for a while just stock and see if this happens again. If it does, there's something wrong with your phone, but i don't think that's the case.
Try and tell us.

diego9016 HugePotato thanks for your answer! is there any way I can save my data first before flashing?
sensei_sai how do I perform the hard reboot? if I press power and volume up the phone does 3 vibrations, then nothing. what next? how do I hard reboot?
thanks for your help!
I'm currently travelling but when back home in a week I'll definitely go back to stock. But in the meantime, I'm so anxious to save the data stored in the phone.
thanks again!

When I put it on charge the red led blinks regularly as usual. Apart that, nothing else.

Have you tried to repair using Sony PC Companion?
That usually helps me if I get stuck

Thanks, I read that post. Interesting, but basically no solution except getting the phone replaced under warranty. I'd go for that, but I wish there was a way to save my data first. I've something in the phone only with no backup.

for my phone was also blinking with a red light when put for charging through the usb or even the charger and then i later found out is because i locked my bootloader when i was in root and had to reflash the stock rom to get it back up

Did your pc recognize your z2, because I can't seem to get it work on my pc to flash a stock Rom. I only get a blinking red light and when I press the power and volume up I get 3 vibrations that's about it.

when I connect the phone to the USB I see that the laptop tries to install the drivers and it fails.
But this is my work laptop and I cannot install sony drivers. I don't know if my desktop at home would recognize the phone. I'll try when I get back.
For the rest, the experience is as discribed by malek777, doing power and volume up I get 3 vibrations and that's it.
I fortgot to mention, I rooted the phone without unlocking the boatloader.

I figured out a way to use the companion app to go back to stock. When you get to the part in repair my device to connect your device, phone must be plugged in.
Hold the power button and volume up, once you hear the 3 vibrations let go of all and hold volume down. You will see a red light and then a green one. You're phone now in download even though there nothing on the screen.
Let me know if this works for you.

Something similar happened to me, I know that's a little silly answer but can you tried charging with another charger/cable?
