Phone won't boot past Sony screen

[SihaJenova]

My Sony Xperia XA2 turned itself off despite the battery being at 37%. 
When I tried turning it on again it got stuck in a reboot loop. 
I cannot boot it in safe mode either.
Removing SIM and SD card makes no difference.
I have tried the Xperia Companion Softawre repair and after following all the steps it says the software repair has bene completed successfully, but my device will still not turn on. 

Is there anything else I have not tried yet?

Hi @SihaJenova, sorry to hear about your device.

The software repair is the last thing that you can do on your own and since this didn't help, I would recommend that you get in touch with your Local support team so they can arrange a repair for you, or if there is a service centre in your area, they will provide you with an the address.

Let me know how it went!
