I am unable to reset my huawei mediapad T5 to factory settings.

Reset reasons: All screen locks are automatically getting unlocked with magazine unlock.

Welcome to Android Central! Can you give a few more details about the problem? Are you saying that with Magazine Unlock, the phone screen automatically unlocks, as if you already entered your password or PIN? Are you certain the Automatically Lock interval isn't set to a long time (like say, 15 or 20 minutes)? If the Automatically Lock interval is a long period of time, the screen won't lock again for that amount of time.
