Siguro paps need factory reset kana. Okay na ung unit ko need lang pala magwait ng 24 hrs before logging in ulit.I have the (almost) same problem with my cherry flare... Since few months, out of nowhere, I always get a notification saying "Google account action required", then when I want to login... ayaw! Even if my password is good... I don't know how to get rid of this notification. Maybe a factory reset? but in this case, I will lose all my apps and settings... Magulo talaga!
