In the description, I left links where to buy all the necessary tools.
Before you start, remove the battery.

Be careful with the thermal compound, it will be reused when reassembling
the drone.
Some ribbon cable connectors are additionally fixed with silicone glue.
First, remove this glue, then you can safely disconnect
the cable.
Peel off the black tape inside the drone body.
This tape holds the mainboard inside the body of
the DJI Mini 2 drone.

The most common cause of drone motherboard failure is water damage and further oxidation
of the components.

the motherboard may resolve the issue.
After installing the motherboard, you will need to calibrate your DJI Mini 2 drone.
Some calibration processes can be done with the DJI mobile app, but for some processes,
like camera gimbal calibration, you will need to use additional software, in the description
