How to unlock Xiaomi S2: all ways to restore access to the TV

Locking a Xiaomi Mi TV S2 is a nasty situation that users face after a forgotten password, software failure or binding to someone else’s Mi Account. Unlike smartphones, unlocking smart TVs has its own nuances: no physical Reset button on the case, binding to Xiaomi cloud services and manufacturer restrictions. This article covers all current unlocking methods – from standard reset through menus to bypassing protection with service commands.
