The flight controller houses sensors and firmware that are critical to the drone’s functionality. If your drone experiences in-flight drifting or errors with the IMU after calibration, your flight controller board may need to be replaced. To replace the board, you need a JIS #000 screwdriver, a 2mm hex bit, a 1.5mm hex bit, and a metal prying tool. Take special care when removing and installing the U.FL connector.

Great guide but there should have been step 14 to show how to put the control board back on top of the isolators.

Also I found it was not necessary to remove the bottom shell to remove and replace the control board. There is enough room to remove and replace with the shell in place and this will greatly decrease the time required to do the repair. I used the rounded edge of a small flat screw driver.

The replacement of the board is a challenge and that is where I got stuck. I used monofilament fishing line. Make a loop in the line and insert the loop through the mounting hole in the board. Pass the loop over the isolator ball and into the groove around it. Bring the mounting board into contact with the isolator ball and gently pull the fishing line loop and pull the isolator ball up into the mounting hole. If you are lucky, the ball will come through and flatten itself out as is is supposed to. If not, use tweezers to grab the ball and gently pull it up through the hole.
