Hi all i purchased a 10 inch megapad 8 tablet with android jellybean 4.2 loaded system - i have somehow managed to mess it up - i switch it on and only see a battery charging screen that does nothing? i have tried the on off and volume re-set way of re-booting but it does nothing? i think i need to fully reload the jellybean system again and desperatley need a link or info of where i can download it - then when i have it do i need to load it to an sd card to start re-load? pleased for any help thankyou paul:'(
