Ayúdame a identificar, rootear e instalar la recuperación personalizada de mi tableta

Mi amigo le dio una tableta. Quiero rootearlo y modificarlo para poder usarlo, pero después de 6 horas de búsqueda me di por vencido. ¿Cómo rooteo esto y averiguo qué dispositivo es?

Después de horas de navegación, terminé con estos modelos de tabletas:

• WM8850-MID7038

• RS2906-MID7038

• (Touchmate) TM-MID730: probé el proceso de enraizamiento de esta unidad en mi tableta y mi tableta encontró un bucle de arranque

Quisiera saber como instalar un recovery personalizado y como hacer el proceso de rooteo.
