Hey guys,

I didn't found a similar topic, maybe you guys have an idea...

Yesterday before goin to sleep my Xperia X Compact has 8% battery left, I connected it to the power supply and went to sleep. Next morning the phone reboots -> black -> Sony logo -> "powered by android" logo -> black -> Sony logo -> android logo -> black.

I tried some combiantions like hold powerbutton for 10sec, power and volume up etc. now it changed from sony logo -> andro -> login screen -> reboot/black screen.

I tried to connect to pc's but it wont work. anyone got a similar problem and maybe have an solution?

thank you

You may have to use Xperia Companion and follow the directions for the software repair. It might involve holding the volume down key when connecting the phone to the computer with a USB cable. In that case your phone would be reset and you would have to use a Google backup afterwards.

In general it's not a good idea to let your battery drain below 30%, if at all possible.

Thanks for your reply. I used Xperia Companion but I says no phone connected. But I can't connect via windows too - there is an error with MTP driver, PC tries to install it from the phone but after a while it says fail. I also tried to manually install the mtp driver via sony website and tried windows help but it wasn't successful. I removed the SD-card too with same result.

I think I have to send it to Sony and hope they can repair it - at least I still have warranty..

How did you get the phone to recognize it was connected to the computer?

@jp241

Try connecting your phone to a PC using Xperia companion on the computer. There is a special mode that's used for software repair (as a last resort, as it will reset your phone).

If you haven't tried this already, Xperia companion will give you instructions.

Thanks but I followed the instructions. Nothing. The phone just blinks red and green. Companion never sees it.

Sorry, but it sounds like you will need to bring it in for repair in order to fix the problem.

One more try to get it recognised:

Search in the home menu of this forum for Information, then search for FAQ, then search for hotel for Xperia companion.

Then read point 2B and your device will be recognised.

First charge to >80%

Please describe again. Those instructions for the forum do not make sense and don't work.

@jp241

Have you reinstalled Xperia Companion?

Is the phone fully charged?

Have you updated JAVA on your computer?

how did the issue first started?

Re: Reboot, reboot, reboot...

jp241 — Mon, 04 Mar 2019 18:45:59 GMT

Yes, did all those things.

I don't know exactly when it started. Sometime in December. Maybe after the latest Oreo update?

The charging port started to malfunction in December so I replaced it.

I don't know if this started before or after replacing the port. The new port charges reliably again. But the phone won't recognize when it is plugged into a computer. No menu.

Hi @jp241

Answering this question:

Please describe again. Those instructions for the forum do not make sense and don't work.

Did you notice this line:

2B. If the device can't be detected or powered on, or if you it's a SmartWatch 3, make sure you have ticked the box in the bottom left corner "My device cannot be detected or started, or is a Smartwatch 3" and then click on "Next".

The other thing is that with my USB cable and my device, it won't detect the device, but when I plug in the USB C plug the other way round (turning it 180 degrees) it does detect it and operates as expected.

(I do seem to have a crippled cable or something {not Sony but from the local supermarket} )

Re: Reboot, reboot, reboot...

jp241 — Mon, 04 Mar 2019 23:46:19 GMT

Yes, I checked that box.

Yes, I turned the cable over and tried different cables.

I had the same issue. Yesterday I've done the software repair with Xperia Companion and everything was working again.

But this morning I've noticed that my battery was down again and after recharge I had the same problem again. My phone is constantly rebooting. so I can start all over again.
