Hello all ! I am pretty new in using android so I can use some help. I have Xperia Z 3 model D6653. My customization version is: 1288-4310_R15B and I believe the phone is created for Honkong. Yet I am from Bulgaria and the phone is bought from here. So there are two questions : 1. Is there a problem with OTA update of Lollipop with my phone or I just need to wait more time ? 2. Can I flash the phone with Flashtool without being rooted to the Lollipop ?
