Recently Sony has launched the Kit Kat 4.4.4 on the T-Mobile Xperia Z1s. I have the Original 4.3 Jellybean Rooted. I would like to update but I downloaded the update thru my phone and it gives me the DEODEX menu I think is what it is called. I am a newbie or a beginner in this. I did the root myself reading and following steps. Is there anyone who can help me out because I know the Z1s comes with bootloader locked. I had to rooted not like many other phones with just one click or a few steps and its done. Please don't judge me or tell me What I should Do. I came here because I know you guys are the best and know WAY MORE BEYOND I know. Please Let me know how to update it with out loosing any info or root. I do not run custom roms, I have also always wondered what are those for, what do they do. But I do not modify anything on my phone but just the SuperSU that grants permission to certain apps that need root access.
