Hi all I was using my tuglyfe dna 200 when it suddenly died on me so I thought the battery had died so I plugged my charger into it but it wouldn't do anything until I took my atty off it and then it came on but the screen is flashing but not going off completely....the battery has 50% charge but when I unplug the charger the mod will not turn on at all....I have connected it up to escribe software and it detects it but same thing happens as soon as I unplug usb cable
