I have a tablet manta mid712 (jellybean 4.1,Cortex-A9 Dual Core 1.2GHz,512ΜΒ RAM).Lately when i boot it,it stucks on the android logo and then it needs reset to work again.Then after 2,3 boots it happens again,and that happens all the time.I ve done reset and deleted all data,also from sd card (internal+external).Also i tried not to install anything after a reset and again it wasnt booting after i have closed it.I searched all around internet but cant find a solution.
