I downgrade my phone and its work android 6 but if i want to reupgrade to 7 continuously rebooting. How to delete all partitions or what should i do?

Sony Xperia XA Ultra F3211

Edit: I solved the problem. Via Logcat in Android Studio, I saw that the last error-causing app before the phone shut down was com.sonymobile.coresettings I tried to uninstall this application, but it could not be uninstalled because it was a system application and I don't know why, after this process I started not getting any errors from Logcat and the phone did not restart either. Now I have to interact with adb on every boot.
