You may have destroyed your tablet!
The power goes through the DC in jack, through chips on the board, through wires to the battery. You may have destroyed one or more chips on the board.
ie. tablet should still power on even with dead battery if plugged into charger. Did you try this? If yours is not turning on while plugged in that tells me you broke some chips on the board.
You should still try "reset" button if your tablet has it. Also, you can try reflashing firmware to it to see what happens. At best, high voltage wiped out ROM & maybe destroyed battery. At worst, it burnt out one or more chips on the PCB/board.
*MINIX NEO X5 (RK3066) - OK. Not fun because uses mouse cursor.
*YUANDAO N80 DUAL (RK3066) - Very good
*CUBE U30GT (RK3066)- Defective; buttons broke in 2-3 weeks; Bad quality control!!! I will never buy a Cube again!!! - Very good while working
*WOPAD I7 (RK2918)- About OK. Sluggish because has weaker ARM chip (RK2918) & less RAM (512 MB).
