  • Free the clasps along the battery slot. And the push the front assembly out from middle housing with effort.

  • We can see the USB board but we can't tear it down directly. Because 1. The USB board flex connector is connecting on the back of the motherboard. 2. If want to remove motherboard, the LCD screen need to be removed at first. 3. The USB board assembly comes with two touch keys together but they are placed under the touch panel.

  • So we have to remove the motherboard and LCD screen at first next.

  • It's complicated to do Samsung Galaxy Note 4 USB board assembly replacement. We have to replace the LCD screen and motherboard at first, please be careful.

For anyone having problems connecting the pins at the back of the motherboard, specially that pin the is next to the power button, stick something small and nonflammable the pin of the screen. Since this pin has a lot of play in some cases, sticking something under it will bring it up, making the motherboard connect with the LCD screen pin.

why do you need to take the full LCD off risking it braking. You could just heat the bottom and separate the touch buttons and home button.

I advice anyone going to attempt this to not take the full LCD off or you will be paying out another £140 for a new screen.

Also save your self time don't take the motherboard out.
