Soft or Hard Resetting

[NebilRafi]

I got some problem while playing YouTube videos on WP 8.1. If I reset my phone ( Soft/Hard) will it take back to the WP 8 OS or the existing OS. I am not ready to download the whole software. Is the effect same if I do a hard reset.

Hard reset will format your phone storage and OS will remian wp8.1

Soft Reset: No data lost. Nope, none whatsoever.

Hard Reset: Nukes your personal data and apps on the phone, but your phone OS will never go backwards.
