Unlock Bootloader

[UnlockBootloade]

Please give us a bootloader unlock procedure for

ASUS Zenfone 5Z (ZS620KL)

Currently, this phone is not even patched to the latest security update. I want to be able to use the product I paid for as intended, and I want to flash whenever firmware I like.

For ZS620KL, there will no longer be any system updates and maintenance (including ZenUI Launcher, server & unlock tool). Sorry for any inconvenience it may be caused.
