Step 1: Enable USB Debugging
Different Android versions have different ways. Take Android 5.0 Lollipop as example. Other Android version please refer to
How to Enable USB Debugging Mode on Android
- Click Menu button to enter into App drawer.
- Go to "Settings".
- Scroll down to the bottom and tap "About phone" or "About tablet".
- Scroll down to the bottom of the "About phone" and locate the "Build Number" field.
- Click Menu button to enter into APP Drawer.
- Tap the Build number field seven times to enable Developer Options. Tap a few times and you'll see a countdown that reads "You are now 3 steps away from being a developer."
- When you are done, you'll see the message "You are now a developer!".
- Tap the Back button and you'll see the Developer options menu under System on your Settings screen.
- Go to Settings>Developer Options>USB Debugging. Tap the USB Debugging checkbox.
USB Debugging should only be enabled when you need it. Leaving it enabled all the time is kind of a security risk for that this mode grants you high-level access to your device.
Step 2: Boot into Andorid Bootloader.
Every phone is a bit different to another when booted into bootloader. But most of modern devices boot into bootloader by turning off the device, then hold the "Power" and "Volume Down" buttons for 10 seconds before releasing. If this method doesn't work well on your device, you had better refer to the Google instructions.
Step 3: Flash TWRP to Your Android Device.
- Connect your device to the PC with a USB cable once in bootloader mode. The device should indicate that the device is connected.
- Open the folder of twrp(Downloaded from link).img by using the mouse on the PC. "Shift+Right Click" on an empty area and choose "Open a Command Prompt Here".
- Run the command: fastboot devices. The command returns a serial number, indicating that it can recognize your device. If it doesn't, check which step you have done with mistakes.
- Flash the TWRP once the device is recognized by fastboot. And run the command fastboot flash recovery twrp filename(Downloaded from link).img.)
- Results of flashing. If all goes well, you will see a success message in Command Prompt window.
- In Command Prompt window : adb reboot.
