encryption stopping 4.4.4 upgrade

[pimlico]

Any ideas?

It starts upgrade then reboots with greenlogo and before next step the encryption box appears with pin request which then loops out if install and back to 4.4.2

How are you updating - Via OTA or Pc Companion - I know that the OTA update is slightly smaller than the Pc Companion firmware so this may account for the hindrance you have

You might need to perform a factory settings reset first.

You may need to perform a software repair using PC companion.The process will erase all internal memory.You might need to charge your device for about 1-2 hours before so the device has at least 60% battery.

Make sure the device is not connected to computer or laptop and turned off (sometimes you have to press power button and volume up until the device vibrates 3 times or on some devices you have to press the small button near the SIM tray or on the back of the device).

Open PC companion->support zone->phone/tablet software update->repair my phone/tablet blue highlighted.Follow the steps given,do not connect your phone until prompted to press volume down while plugging USB cable. If PC companion does not start the repair process, you might need to run it in compatibility mode with Windows 7 (in some cases XP).
