Display light is not working check this solution... make this jumper 

Hey all,

I recently upgraded to 6.0.1 using flashtool only to find out that root is going to be tricky to gain for locked bootloaders. So I downgraded back to 5.0 build 26.1.A.3.111. After the downgrade I noticed my LED wasnt lighting properly anymore. When i do a test through #*#*7378423*#*# it lights all three test colours, but when I get a message or plug my phone in to charge it seems to light sometimes and not others. I tried using pc companion to repair my device but still had no luck getting my LED to work. It seems as if marshmallow left something behind that wont go away and is wrecking led functionality.

Anyone have a possible solution?
