Learn how to wipe the HTC One (M8) using the hardware keys. If the HTC One (M8) is not working correctly, you may need to master reset it and also clear the cache partition. These two resets clear different parts of the HTC One (M8) storage. Unlike a master reset, wiping the cache partition does not delete your personal data.
