I must begin by saying,I hate the Lollipop update on XZU. The clownish bright colors and whites. I so badly miss the dark default Sony theme of Kitkat 4.4.4 The notification dropdown in all black just looked so sexy. All text and images used to pop on it. Now it just looks so stupid in white and grey. Earlier I used to just love looking at my phone's gorgeous display. No more..Lollipop ruined it totally and I regret my decision so badly to update the phone.
Is there any way I can rollback to Kitkat 4.4.4? I want to keep the OEM rom.
Solved! Go to Solution.
I wanted to revert back to KitKat so followed the guide in flashing firmware to my phone. I have completed the steps until the last (Flashing finished. Please unplug and start your phone.) I disconnected it. Then I powered it on. It was fine until it suddenly stopped during the startup process (purple startup animation). Then it entered into a boot loop. Now I have to do a software repair.
Any other tips or advice? Badly need it. 
reflash the phone or repair it with PCC
press and hold power & volume up for 10 seconds to turn it off
I tried repairing it with PCC. The repair failed twice. It says check your internet connection. But the connection is fine. What should I do? Should I try to flash Lollipop instead?
@uliwooly
that's odd, how slow/fast is your internet connection?
go to speedtest
also disable your firewall and antivirus and then try again.

I was able to repair it with PC Companion. Now I got 5.0.2 Lollipop back. THANK YOU SOOO MUCH!!!
