Is it possible to change the core board (with a brand new one) and the mavic mini automatically pair with the gimbal and leave no errors? Looking for anyone who has changed one.

Hi. Thank you for reaching out to DJI Forum. With regards to this concern. It is not advisable to do any DIY repairs on the DJI Mavic Mini this may cause additional damage to the drone and may void the warranty. Kindly please contact our DJI support team to assists you better and to ensure that the drone is properly repaired and tested. Thank you.
