What is Unlock Bootloader ?

A Bootloader is a code which runs when we turn on our device. This code initializes some hardware and then loads the kernel and ramdisk, and gets the boot process going. So this process is known as Bootloader. The same concept applies to all the technology stuff such as Laptop, PC, Smartphones and any such device. Every Android OEM manufacturers lock the bootloader even though it is an Open Source. So if you want to try any CUSTOM ROM, it is impossible to load the CUSTOM ROM without the Unlock Bootloader. So Manufacturer made a policy of making the smartphone with Unlocked Bootloader will void the warranty. They want you to stick with the Stock ROM. Unlock Bootloader allows you to Root your android smartphone, Flash TWRP and Custom ROM in a simple easy method.

Steps to Unlock Bootloader on any ZTE Smartphone

First of all enable the Developer Option
To Enable the Developer Option, Go to your Settings -> About -> Software Information -> More -> Now Tap on the Build Number 7-8 Times until you see a toast message “Developer option enabled“
Go back to settings -> Now you need to enable the OEM Unlock by going to Settings -> Developer Option and Enable OEM Unlock and USB Debugging
Download and Extract the Downloaded ADB fastboot Zip file on your PC
Now connect your phone to Computer using USB Cable.
When you connect your Phone to Computer, please wait until all the drivers get installed.
In your ADB fastboot folder open a command prompt window by pressing Shift Key + Right Mouse Click
Now type the command in your command window
```
adb devices
```
If you see a pop up to allow USB Debugging on your phone, Click OK
Now type the command below to reboot your phone to bootloader
```
adb reboot bootloader
```
Once your phone reboot into bootloader, make sure your phone shows the bootloader locked and then type the command below to make sure fastboot drivers are installed properly.
```
fastboot devices
```
This command will list the connected devices. If your phones serial number shows up you are good to go and may continue. If the phone is NOT listed this indicates that your drivers are not installed correctly. In order for you to continue you must fix your drivers so that your phone is listed under fastboot devices.
If the phone has been recognized by the command above, proceed to unlocking the bootloader with the following command:
Remember that this step will wipe EVERYTHING off the phone
```
fastboot oem unlock
```
After the above command has finished executing, run the following
```
fastboot reboot
```
The phone will reboot. Wait until the phone has fully booted up into android, and enjoy!

I hope you have successfully Unlocked Bootloader on your ZTE phone.

Yes. I have activated the developer option. I’m able to get USB debugging and other developer options except “OEM unlock”.
I’m using the latest International ROM from Germany. I’m guessing this ROM version hide the “OEM unlock”

  Nachdem man die Entwickler Optionen mit 7* tippen auf “Über das Telefon -> Build-Nummer” aktiviert hat, erscheinen inden Einstellung unter “Mehr -> Entwickleroptionen”. Darunter befinden sich die “OEM-Entsperrung” und das “USB-Debugging”.
  Bei mir geht das Un-Locken ebenfalls nicht. Ich habe die Build-Nummer: NX551_J_ENCommon_V1.11
  HILFE!

I have the z965 handset (zte blade x) and when I type the command ‘fastboot oem unlock’ all I get is “waiting for device”. When I type ‘fastboot devices’ it does nothing. Do I have to re-install the drivers for my phone?

  If it shows waiting for device, then it means your device is not connected properly. Make sure you have proper drivers installed. Also check if the USB Cable is working properly to transfer data.

so I’m using the zte z899vl and I can get it to connect to adb but when I use the reboot-bootloader command it just reboots the phone back to the default kernel. It also said something about a production model when I tried the adb root command. what should my next step be if I don’t throw it up against a wall first lol?

    I appreciate the effort in the tutorial, but the title is then misleading; ‘How to Unlock Bootloader on any ZTE Smartphone’ ?
    I’m trying with the KIS1 MAXX (ROM ZTE_Kis_II_Max_MT6572_03042016_4.4.2) and I get no response from ‘fastboot flash unlock’ or ‘fastboot oem unlock’.
