 **Power-off** the device, then power-on using **VolumeUp + Power**. You will enter the **Boot mode select menu**, choose **Recovery** (using VolumeUp to choose and VolumeDown to confirm). You will be presented with a **Broken droid image**; press again **VolumeUp + Power** (sometimes it is required to keep them pressed for about 10 seconds) to enter the **Recovery menu**.

 === OEM unlock ===
-Now you can actually unlock the bootloader; once unlocked, you can boot the phone from a custom operating system image (we will use TWRP because it can install Magisk). Beware that OEM unlocking implies a **factory restet**: you will loose any app and any customization you made on the phone.
+It turned out that performing this step **is not strictly required**: if you flash the TWRP Recovery using the **SP Flash Tool** graphical software, you don't need to issue the ''fastboot oem unlock'' command and so **no factory reset** is performed.
+Otherwise, if you wan use only the command line, now you have to actually unlock the bootloader. Once unlocked, you can boot the phone from a custom operating system image (we will use TWRP because it can install Magisk).

 Once rooted, the **On-The-Air updates will fail** because almost certainly a new kernel with dm-verity enabled is insalled. This will detect the modifications to the system partition, **freezing the bootstrap at the ZTE logo**. Your chance is to perform a restore once notified that an update is available. Restore the **boot.bin**, **recovery.bin** and **system.bin** images from the backup before root. After the update is installed, you have to reinstall TWRP and Magisk.
