I have an ellipsis 7 tablet and yesterday i decided to give it is update. my tablet started to up date and then the screen turned black. when i finally turned off i tried to turn it on, it showed the powered by android screen and then turned black while still lit up. ever since i tried to update it that is all it will do besides show me the battery symbol when i plug it in. Ive have tried everything, charging it, factory reset letting it die completely and trying to reset it, everything. Why has this update killed my tablet and can you please help?
