XA stuck in startup loop

[ackers24]

My Sony Xperia XA is stuck in what seems to be a startup loop (the white screens show up with 'sony' 'android' and 'x' and then it goes black.) 

I have tried the Xperia Companion multiple times, I have tried holding the volume and power button to fully shut it down and then restart it but it is still stuck in the loop. I have searched the forums and nothing seems to be working, any recommendations?

When you have tried Xperia Companion and you did a successful software repair (battery at least 80%?) and it still your phone won't boot then consult Sony support (in the support app) and send your device in for repair.

THis happen since android 7 has replaced 6.0, my xperia XA won't boot after I use the app that manages memory space by moving to SD card some apps...I own two Xperia XA , total 5 times locked on the screen XPERIA at launch and it becomes never black...if someone can tell us what to do (patch...) instead of reinstalling all it would be nice.
