How to Unlock your Bootloader on Zenfone 5 (A500CG/A501CG) [With Video]


Donwloads:
Method 1 toolkit :
Donwload from author’s blog here.
Method 2 toolkit :
Download from my Google Drive here.
Fastboot tools : Download from MediaFire here. 
By the way if you have
followed any of my previous tutorials like Multi-user mode or Installing Xposed
on Lollipop your Bootloader is pretty much unlocked. Still repeating the
process double ensures it. 
Okay so before we get
started with this let me remind you again that the official method works on
Kitkat and not on Lollipop so you need to do it manually. This will void your
warranty and prevent you from getting OTA updates though I doubt ASUS will ever
push out any..
SO PLEASE DO THIS AT
YOUR OWN RISK!
There are two methods as
I will show in my video too, so if you don’t like reading see the video from
the Link below.
 METHOD 1 : So the first method is an automated method and made by
SatySatsZ B and you can download his tool from here.
So once you download the
tool and extract it with the password connect you phone via USB(make sure ADB
Debugging is enabled) , run the Bootloader-Unlock_Relock.exe and press 1 and
hit enter. Let the process complete and you will have a unlocked boot-loader
and you can progress with installing CyanogenMod 12.1 on your Zenfone. 
 METHOD 2 : The second method is manual. You need to download the
Toolkit from above. 
Extract the files and
copy them to the Fastboot folder. If you don’t have it you can download it from
above.
Connect your phone via
USB with Debugging enabled and in the fastboot folder press CTRL+SHIFT+RIGHT
CLICK and select “Open command window here”
Then type out this
command and hit enter
          adb
reboot bootloader
Your phone will reboot
to your bootloader. Once there you need to flash the three files. Type in this
command first and hit enter.
     
    fastboot flash fastboot fastboot.img
 when that is done you need to reboot the
bootloader. Type the following command and hit enter.
          fastboot reboot-bootloader
When your phone reboots
into the bootloader you can continue to flash the second file. Type the
following command and hit enter.
     
  
     
    fastboot flash dnx dnx_fwr_ctp_a500cg.bin
 When that is done go ahead and flash the last
file. Type this and hit enter.. 
     
     fastboot flash ifwi
ifwi_ctp_a500cg_unlock.bin
 Now your bootloader is unlocked and you can
continue installing CyanogenMod 12.1 on your Zenfone from the link above. If
you don’t want to read, follow this video from the link down below.
Don’t re-lock your
Bootloader after flashing CM, re-lock only if you are going back to the STOCK
ROM.
