For SD card replacement:

Follow above guide to step 18. Remove the bottom right flex cable. There will be a hole under the cable to access a screw in the battery compartment, which holds on the grip. Remove the screw. Remove the one remaining screw in the corner of the battery compartment. The grip should now come loose. Remove the grip. Remove the two screws holding the SD card board on. Disconnect the small two wire cable from the top of the board. The board should now slide out. Disconnect the flex cable from the old board and connect to the new board for reinstall.

I did this for a Sony A7S and all is working well.
