Now let’s explore the steps

STEP 1: Download and Install the android USB drivers on your computer. In case you have already installed   them, you can skip this step.

STEP 2:  Switch Off you Android Phone and Remove the battery in case it is removable.

  2. Select Download Only and uncheck preloader.
  3. Now click the Download button to start the downloading process.

STEP 5: After completed all the above steps, connect your smart phone to your system using the USB cable and press any button other than power button so that your system will detect your device. You can use volume buttons. (ex: OPPO is Volume Up)
