I did the most recent update for my Sony Xperia XA1. It completed then restarted itself. It was then on the 'Sony' white screen for a while, at this point, I still thought this was part of the update. This then remained for the next 2 hours, which didn't seem right. I've tried holding the power and the volume up key, waiting for 3 vibrations. It turns off, then I can power up again, but straight back to the Sony white screen. I've downloaded Sony Companion but the device won't register. I've took the SIM card out and tried restarting and back to the Sony white screen. Any tips or advice would be hugely appreciated. Thanks!
