    • Using a nylon spudger, push through the hole at the top of the memory card holder to slide it out.

    Does “slide it out” refer to memory card holder or the memory card itself?

    Photo useless. Cannot see where “hole” is.

    • Remove the 10 4.0 mm Phillips screws on the back of the phone using the #00 Phillips screwdriver.

    • Not needed, but Tweezers can be helpful in removing the screws from their holes, as their size makes removal a tad difficult.

  7. bX1HVERnf34IMKoy

    • Starting at the USB port, slide a plastic tool around the perimeter of the phone between the rear housing and frame. As you work your way around the edge you will feel the clips release.

  8. WnKkekWbFfE23jQR

    • Carefully separate the rear housing and the mid-frame to reveal the inside of the phone.

  9. FyD6A2GTuZDDKVLB

    • Remove the 2 flex cables shown that attach to the USB board, Tweezers can be especially helpful here.

    Attention! Some Models have also an Cable on the right side for the 3G-Module. Also this have to be removed. In this case the Module is also bigger and fixed with 2 tapes.

    • Use a suction cup to pull the screen away from the frame and create a small gap.

    • This should not require excessive force. Apply additional heat as needed to soften the screen adhesive.

    • Cover the screen with a layer of packaging tape if severe cracks or screen damage prevent a suction cup from obtaining a complete seal. The Galaxy S4 Mini also has enough of a gap between the frame and the screen to insert a jimmy or plastic opening pick. Carefully apply heat as needed, and wedge the screen free.

    • Slide the plastic opening pick along the edge of the screen to free the screen from the adhesive.

When removing the digitizer be sure to disconnect the connector for the sim card/sd card before removing the digitizer.

Just FYI, having got this far and realised you can just replace the screen if it cracked. It looks like you just heat up the screen to soften the seal and pull off the screen without the need to replace the digitiser. It’s certainly quicker, easier and cheaper to do this is its just the screen that’s cracked. I need a digitiser now as it didn’t survive the strip down. Not sure if its economic to repair now!
