  2. Make sure your Android device battery is charged at 80-85%. Because, if the phone suddenly switches off during the process, you could cause damage permanently.
  3. [Important] Copy all backup files from internal memory to the computer because the internal memory will be cleaned up while unlocking the bootloader.
