It’s a while back since ASUS released the official bootloader unlock tool, and I managed to download it and give it a try, after all I do like to unlock ZenFone 2 to its full potential. Some users have reported that the tool caused issues to their ZenFone 2, and ASUS removed the tool temporarily whilst getting it fixed. Bummer, but it’ll return soon.

WARNING : Heavy use of jargon words ahead! Also will void your warranty. We here at NLT are not responsible for anything happened to your device!

So anyway, it’s simple. Here’s how I did it.

MSI Creator 17 Mini-LED

1. I downloaded the tool, installed it.

The app icon looks sketchy, but I assure you that the app is at its bare minimum in terms of design. After all, it’s a one-time-use app anyway.

2. Open the app

Self explanatory right here

3. [!!!] Read the notice!!!

By doing this, it most definitely will void your warranty. Don’t say I didn’t warn you.

4. Security measure

Make sure it’s not your troll friend who wants to unlock its bootloader!

5. Hit the button

And wait for a short period of time. A message saying something along the lines of “successful” will come out, assuming nothing goes wrong. Then you’re done!

6. Hit restart

You’ll see that the boot logo’s colours are now inverted. That means it’s unlocked!

7. ADB/Fastboot now please

Connect the phone, enable USB Debugging, get ADB running and do these. Of course, you’ll have to find the appropriate files and steps on how to install custom recovery and custom ROMs yourself.

  1. adb reboot bootloader
  2. fastboot flash recovery recovery.img
  3. Select boot to recovery
  4. Enjoy the fun!

Personally, I’m running BlissPop ROM for the ZE551ML. Runs excellently, but a little on the hot side. Might change back to stock, just because how well ASUS actually optimized ZenUI.
