Hi, recently I bought a Sony Xperia Z C6603 and it was only up to android 10.3.1.A.0.244 in the software updates, so it was way behind. I tried to update the software to 10.3.1.A.2.67 but it just rebooted and said that it could not install. so i tried again and again. Ive had the phone for a week now and I've tried updating the phone once every day. Something is not working. I tried everything that was suggested by Sony for other people who had the same problem. Still nothing has worked in trying to update my phone. when I go on to PC companion, the app says that the phone is "up-to-date" with the software. ive tried everything. can someone please help me!
