Hi @Raja123456, sorry to hear about this.

Do I understand correctly that the battery ran out during a software update and when you try and power on the phone now you can't get past the Sony logo? If that is correct, try removing your SIM and/or SD card(s) from your phone and see if you are able to get further before the phone is powered off/restarted automatically.

If there has been no change, you will need to perform a software repair using Xperia Companion. Do note that this will delete all data stored on the internal storage of the phone and since you can't unlock it, you will not be able to create a backup.

Let me know if that helps!
