please help me how to solder the flex cable to the motherboard
how much this board..???
can you post this board and how much...????
There is still no answer for the flex cable to motherboard
Nice and clear disassembly instructions.
But Why change the board when the problem is only the power button?
What needs to be replaced is the 'faulty' Power Volume Button Flex Cable.
It will take an experienced phone technician to replace that part.
The main flex cable is all one piece. I think they use z axis conductive tape to bond to motherboard
Very exact an helpful, better than Videos. But after Step 26 I need one more hint:The leftmost 2 wires of the black mainboard ribbon end in a metal case in the lower left of the handy. I cannot see if this 2 wires end in an connector. Can you give me a hint how to detach these 2 wires? I would be very glad, if you can help me.
Thank you very much.
