HI a have a same problem but i had almost resolved it. Like you i had flashing name logic over and over. It probably caused by damage of freezing i think after that started anyway.try to plug recharge couple minutes than take it out and try to start it,chech button hold if it is not pushed, if it stil flashes logic try to press the button resset this button is in other side you can see there is little hole here it is.i tryed sometimes couple times to reset after it turned on perfectly.but still have same problem one day it seems works ok and another flashes i think meybe new drivers would help.
