For this step you need,

CP2112 interface adapter.
Dupont line cables connecting cables (Male-Female).

DJI Battery Repair software.
Windows PC.

Download and install the DJI battery killer software to the PC.

Take the CP2112 interface adapter and inspect its pins. You would see seven input pins named VCC, GND, SDA, SCL, WAK, INT, and RST. From them, we just need to use three pins which are GND, SDA, and SCL.

Then connect the CP2112 adapter to the PC using a USB cable.
Open the DJI battery killer software on your PC.

Then click on “Connect”.

Then click on “Read Info”.

Then click on “Unseal” and “Unseal 2”.

After that click on “Clear PF” and “Clear PF2”. Now the PF flags would be clear and the battery would start blinking and the issue is fixed.

Click “Exit” and close the application. Unplug the battery and charge it fully and enjoy it.

Problem 2: DJI Mini 2 is not stable.

Usually, DJI Mini 2 would fly unstably, if its propellers are damaged, IMU (Inertial Measurement Unit) needs some calibration or the Mini 2 aircraft is not connected to a sufficient number of satellites.

Solution 1: Inspect propellers.

Run through propellers through and check whether you notice cracks, or bent on the propeller. If you notice some damage on the propellers, replace the Mini 2 propeller set with a new one.

Solution 2: Calibrate the IMU.

Place the DJI Mini 2 on a flat surface.
Power on the aircraft while its arms closed in.

Open the DJI Fly app and connect to the aircraft.
Click on the three dots at the top right corner and open the menu bar.

Then click on “Safety” and scroll down until you found the ”IMU normal” under the “Sensors” section. Then click on the “Calibrate” button. And hit start.

Once the above steps are done, the IMU calibration process would start. You need to place the drone in different poses to calibrate IMU.
Start with the Mini 2 on its belly and wait until the IMU is calibrated in that pose.

Next, move the aircraft onto its right side and wait until the IMU is calibrated in that position.

Then change the Mini 2 over to the left side and wait until the IMU is calibrated in that position.

Then Stand the Mini 2 on its back ends and wait until the IMU is calibrated in that position.

Then turn the drone upside down and wait until the calibration process goes to 100%.

Solution 3: Wait until at least 8 satellites connect to the drone.

Once you power on the Mini 2, you should wait for at least eight satellites to connect to the drone before the takeoff. If you just take off right away, it’s normal to have an unstable flight.

Problem 3: DJI Mini 2 not taking off.

In most cases, DJI Mini 2 won’t take or is unable to take off because of installing propellers to the aircraft in an arbitrary way. If you didn’t follow the proper propeller pattern to install them chances are your Mini 2 won’t take off even though its propellers are spinning or it would flip to the side. Also if your Mini 2 is inside a Noflyzone you won’t be able to take off the drone without unlocking the area.

Solution 1: Install propellers in the right order.

When you are buying the propeller set for the Mini 2, you would get them in separate packs named A and B.

“A” propeller set has a little bit of bump on the propeller but the “B” propellers don’t have that bump.

The “A” propellers need to be installed to the front-right and back-left.

The “B” propellers need to be installed to the front-left and back-right.

Solution 2: Unlock the area if the Mini 2 is on Noflyzone.

If the Mini 2 is on Noflyzone, you have to unlock the zone before taking off.

How to check whether you are in a Noflyzone.

Connect the phone to the internet.
Open the DJI Fly app and enter the camera view. Then tap on the little map icon in the bottom left corner.

Tap on it again and you would see the detailed map.

Now you would see colored circles and boxes in some places. If you are in a red, yellow, or blue area, you won’t be able to take off the drone casually.
You can see more details by clicking on the area.

If you are in a Restricted zone (red area), a densely populated area (dark red) area or, Regulatory restricted zone (light blue area) you can’t take off or fly the drone in the area.
If you are in the Altitude zone (grey area), Warning zone (orange area), or green area, you can take off the drone without any extra work.
If you are in the Authorization zone (dark blue area), or Enhanced warning zone (brown area), you have to unlock the zone before taking off the Mini 2.

How to unlock unlockable Noflyzones.

If you are in an Authorization zone (dark blue area), or Enhanced warning zone you can unlock those areas and fly or take off the drone inside the area.

Before that make sure you are logged in to the DJI account that is connected to the Mini 2.
Tap on the zone. Then tap on “Yes”.

Then tick boxes asking whether you are bearing the responsibility to fly in the zone.

Then hit Confirm.

The area would be unlocked and now you can take off and fly the drone inside the area.

Problem 4: DJI Mini 2 keeps disconnecting.

In most cases, DJI Mini 2 keeps disconnecting because of low battery power, bad Wifi settings, and electromagnetic interference. Most of the time, electromagnetic interference can’t be controlled by yourself, So the only thing you should do is avoid electromagnetic surroundings such as powerlines, communication towers, and huge buildings when flying the drone.

Solution 1: Charge the Mini 2’s batteries fully before the flight.

Low battery power could cause a poor connection between the aircraft and the remote controller. So make sure to charge them fully before the flight.

Solution 2: Set up Transmission Settings for a strong connection.

Then open the DJI Fly app and enter the camera view.

Tap on the three dots at the right top corner and tap on “Transmission”.

Then choose “Dual-band” as the frequency option.
Choose “Auto” as the Channel mode. Therefore once the drone gets interference in the current frequency range, it would move to the frequency range with the lowest interference. So

Then set up the Downlink Bandwidth to 20MHz.

Solution 3: Use the Yagi range extender to strong connection.

Yagi Antenna for Mini 2 would extend the range and strengthen the connection.

Buy Yagi Antenna for Mini 2 and set up antennas to the remote controller.

Problem 5: DJI Mini 2 not connecting to the phone.
