Steps to Flash/ Install TWRP 3.4.0 on ZTE Axon 7 (ailsa_ii)

Step 1: Assuming you have already downloaded the platform-tools from Android SDK (SDK Manager) platform-tools on your PC. The platform-tools contains the required adb and fastboot binaries.

Step 2: Make sure that the drivers are installed on your computer. Then, skip to the next step.

Note: If Developer Settings and USB Debugging settings are already enabled on your device, as suggested in Prerequisite section, then simply skip the Step 3 and Step 4, and follow Step 5 directly.

Step 3: Now, enable the developer settings on your ZTE Axon 7 (ailsa_ii) Device. To achieve the same, just navigate to the Settings -> About and then find the ‘Build Number ‘, and then tap on ‘Build Number’ for 7 times, this will enable the developer settings on your device.

Step 4: If you have USB Debugging already, then skip this step. If you have not, then open the Developer Options and then enable USB debugging option.

Step 5: Now, open the command prompt in computer/ ADB Terminal, and simply type the command:

adb reboot bootloader

Step 6: Your device should have not entered into fastboot mode. Now copy the TWRP.img file downloaded in prerequisite section, to the same folder where adb and fastboot binaries are located. Rename the file to ‘twrp.img’ and then enter this command:

fastboot flash recovery twrp.img

and then run this command, type:

fastboot reboot

Step 7 (Important): Some devices might not replace the custom recovery automatically during the first boot. You can search Google for key combinations to enter your device into recovery mode. After running the ‘fastboot reboot’ command, press and hold the proper key combination to enter device into TWRP Mode. Once the device boots to TWRP mode, the TWRP will automatically patch the stock ROM, to prevent the chances of replacing TWRP with Stock Recovery.

After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don’t follow this step, you will have to repeat the install.
