This is going to be my first sony phone im unfamiliar with the process of rooting on sony, how do root and get recovery? I believe the zl getting should be boot unlocked.
The best thing to do would be to go through as many (read ALL) the post on all the ZL threads. However, here's the primer.
The first thing to do would be to check if your phone has an unlockable bootloader. Unlocking the BL will allow you to flash custom kernels and ROMS. If you are coming from a Samsung phones, most of them already have their BLs unlocked, so this step might be new to you. Do know that you potentially lose your warranty once you unlock your BL. However, there is a way to relock it. Also, there is a debate about losing Bravia Engine 2 once you unlock you BL.
But, you dont need to unlock BL to root your phone. The dev krabappel2548 has released recovery and root for devices whose BLs cannot be unlocked. You'll find info about it in the Original Android Dev Section.
Might seem overwhelming, but its not. Read up for a couple of days and you will be all set.
Hope this helped.
