I just created a tutorial on how to hard reset TECNO Spark 6 Air phone without using pc or computer. All the steps are included on the video below.

This tutorial is about on how to hard reset (factory reset) your TECNO Spark 6 Air android phone using the Volume Up and Down keys, and the Power button.

This is very useful if you cannot open your TECNO phone and you want to reset it to be able to use it again.

This tutorial will solve:

-if you forgot your password, pattern or pin and Gmail, you can reset it
-if your TECNO is laggy, you can refresh it
-if other apps are malfunctioning, you can also reset it
-other phone errors will also be resolved
