This method for who still locked bootloader, ofcorse unlocked bootloader can do it too but i recomment using flashtool for faster

Dowload

dl1 - flashtool http://www.flashtool.net/downloads.php

dl2 - if you are using kitkat (4.4.4) and not rooted down load 230 kernel version (it only 8MB)

if you already at Lolipop (5.0.2) and want downgrade to able to install xposed, you must down load full rom for C6502 from here http://xdaforums.com/showthread.php?t=2759640 (No need download this if you are using Kikat 4.4)​

dl3 - recovery (no need if you already rooted and installed recovery) http://nut.xperia-files.com/?ql=fecb25893fe92b03904bb4d99596fbb5a0332e84

dl4 - Pre-rooted Lolipop rom, this rom i created by my own and i using it (C6502 10.6.A.0.454 Generic US) https://drive.google.com/file/d/0B5yIIYx6CgloVDBMamZwZjJQdzg/view?usp=sharing

you can create by yourself follow this giude (just use ftf and superSU, dont use recovery to cause loopboot) http://xdaforums.com/xperia-zl/general/guide-root-xperia-zl-5-0-2-t3115227​

dl5 -(option) xposed framework for Lolipop, dowload both XposedInstaller_3.0-alpha2.apk and xposed-sdk21-arm-20150430.zip from here http://xdaforums.com/showthread.php?t=3034811
​

Lets begin

1- Flash kitkat rom (skip if you rooted)

install fashtool to pc and flash rom you got from dl2

How to Install and Use Sony Flashtool on Xperia Devices

if pc didnt recognize the phone mean you miss out driver, just install sony pc companion to solve​

2- root (skip if you are rooted)

- power on phone -> setting -> about phone -> press Build nuber 7 times then press back -> Developer option -> check USB debugging

- open flashtool (may be wait few minutes), connect phone to pc via calbe, wait few minutes then pess root

(i already rooted so it gray, if not rooted it become black), choose SupperSU, wait until it sad and press button "make in rain" on your phone -> auto reboot -> done

keep phone connect to pc​

3- recovery (skip if you are installed recovery)

- unrar recovery tool from dl3, run install.bat -> press 1 (if you choose SuperSU when root) ->press Enter -> wait -> auto reboot.

noitce: When install recovery keep noitice the phone it will ask the the root permision for adb shell and usb debug permission for pc, just allow all if it asked, if you missed just run install.bat again and allow it. affer reboot it will automatic enter recovery mode, just choose reboot to power on the phone.​

4 - Prepare

copy Lolipop rom from dl4 and xposed framework from dl5 (option if you wanna install xposed framework) to Internal Storage phone (dont use memory card). you can accsess it via Computer -> sony ZL -> Internal Storage​

5 - flash rom via recovery

- on the phone open the app with red evil icon (so sorry, i forgot it name), allow root permission, my option is check PhilZ recovery (defaul is TWRP) then choose "reboot in to primer recovery"

- in recovery mode, choose wipe cache, wipe data, wipe dalvik-cache, factory reset. then choose install zip (2nd line option) -> zip from sdcard (1st line option) scroll to choose flashable.zip which you just copy into phone -> comfirm -> wait few minutes untill it done. (do not reboot right now if u wanna install xposed framework or you must start over from step 1)

- option for xposed rame work (skip if you not interesting), choose install zip ( 2nd line option) -> zip from sdcard (1st line option) scroll to choose xposed-sdk21-arm-20150430.zip comfirm -> wait few seconds untill it done

- choose reboot system now, first time it can take 5 or up to 10mins to complete boot, just relax.

- option for xposed frame work, after power on install XposedInstaller_3.0-alpha2.apk to manager.​
