How to Get Official 4.3 Update on Xperia M (15.4.A.0.23 Firmware)

First of all, you have to check whether you got the update. For this either open update center app and check for notification. In case the OTA didn’t bring up for you, you can try with the PC companion software. Simply connect your phone to computer with Sony PC companion and check for software updates. However, the availability will depend on your region and carrier.

NOTE: If you’re on custom kernel or custom ROM, you have to jump back to stock 4.1.2 firmware to get the update over SUS or OTA. Also, you may re-lock your bootloader before upgrading.

If you can’t bear the waiting pain and want to get the firmware right now, ftf is for you. The ftf (firmware) for 15.4.A.0.23 build is already up and you can flash it via Flash tool.
