Huawei's mobile phone needs to be unlocked before obtaining permission, and the official locked it for security reasons.
Preparation for unlocking:
1, you need to apply for the unlock code first (Huawei's official forum has detailed methods).
2. Download Huawei mobile phone unlocking tool (Huawei official forum has detailed methods).
3. Back up the information of the mobile phone. (The factory settings will be restored after unlocking. Need to back up contacts, text messages and other materials that need to be backed up. )
Start unlocking:
1, turn off the phone and start it quickly (set-turn off the fast start),
2. When the phone is turned off (at the volume+the power-on key is kept for more than 10 second), the phone will not be turned on at this time and will enter the bootloader mode.
Tip: If it is turned on, just repeat the second step, and pay attention to check whether the quick start is turned off.
3. Connect the mobile phone to the computer, run the Huawei unlocking tool and follow the prompts.
4. The unlocking process is almost 10 second.
5. After unlocking, the mobile phone will automatically restart. If it does not automatically restart, unplug the battery of the mobile phone and restart it yourself.
6. Complete unlocking.
Second, after unlocking, you can obtain permissions through software, such as Brush Wizard, Zhuo Dashi, Qitu, etc.
