Chosen Solution

So, I was using my oneplus one and it randomly shut off. It wont respond to anything. That means, double taps, any gestures or plugging it into a charger or computer. I know I had enough battery to last about 5-6 hours. It charged just fine. My power button and volume buttons dont work. I think I messed them up while I replacing the screen. Weird thing, the power button worked when I made the switch so I was able to turn on the phone but then just stopped working after it like literally 10 minutes later. I could order another battery, volume and power button. But, I dont know how to replace the volume and power button. ANY type of help would be greatly appreciated!

Hi, Volume and powerbuttons are to be soldered to the main board with the OPO. I would try a new battery or send it to a professional shop to help out with the volume/power issues. -Maxim
