1. Generally, when the motorcycle is turned off, press the start button while holding down the camera key, and never let go of the camera key (you can enter the part by changing the camera key to the letter X). After the recovery interface appears, release it. Or press volume+first and then press the camera key to enter recovery.
2. After the Samsung model is generally root, press the volume down key+dial key+power on key at the same time to enter recovery, or press the voice down key when starting up until the recovery interface appears.
3. Another method:
In the power-on state, click Settings-> Privacy->; Restore factory settings-> Reset the phone-> Clear all contents, let the phone automatically restart and enter recovery. Don't worry, it won't erase any of your contents, just restart and enter recovery mode.
4. In Android phones, most of the recovery is in English, so if you enter the recovery mode by mistake, you need to know the meaning of each option if you want to exit the recovery mode.
