With freshly charged batteries when the fire button is pressed, it says check battery. With the mod connect to charging source it stays on and say the same when you press the fire button. With it not connected it will not stay on and you have to hold the fire button for it to come on. as soon as you let on the button it goes off. In device monitor battery cell 1 is reading 1.13 and cell 2 is reading 5.22. I have tried hard and soft reboot, USB recovery and nothing is happening. Please help.
