    For SD card slot replacement: 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.

    • Lift the motherboard from the camera body.

    • It helps to pick up the right side of the board first, and then work sequentially down the board. Be sure to gently ease the motherboard from its clips down the remainder of the side.

    • Exercise extreme caution when removing the motherboard as it can be fragile, and damage to it could mean the camera will become unrecoverable.

    The manual identifies the motherboard as sy-1022. It has several surface mount fuses. Did you repair your board by replacing these fuses or swap out the board. A repair tech in the US said that when a board is swapped out and data cannot be recovered from the original board, special software is needed to get the camera operational. Did you run into that issue? Also- did you replace the board's lithium battery?
