Mini 4 Pro downward vison sensor error code 1A0100C0

[tpdtopcop]

Crashed drone and broke right front arm. Replaced arm and Replaced Downward Vision System to Core Board Flexible Flat Cable, as I bent one of the pins when I re attached original cable to mother board. Now I am getting this error, however while drone is in flight if you put your hand under drone, the drone rises as if the sensor is working? Can the sensor work but still give this error? Will replacing the sensor fix the error code?
I also calibrated gimble and IMU normal, and firmware flash.

Thanks in advance,

Brad

That error is related to the FRONT vision sensor . you have:
A bad connection or
need a firmware flash or
Calibration issue or
Your forward sensor needs to be replaced.

as I bent one of the pins when I re attached to mother board

Most likely your problem lies here.

Thanks for the reply. I did replace the Downward Vision System to Core Board Flexible Flat Cable because of the bent pin. Are you saying its really not the downward sensor?

there is a chance if that is the problem there are specific instructions on the DJI site you can follow to calibrate USE THOSE.

There is no way to calibrate the downward vision sensor for the mini 4 pro per the DJI website.

Sorry Have you reinstalled the firmware?
Did you do a factory reset (in the Fly app >about>clear all Data> choose > the reset will begin.
If that doesnt do it. Open the Drone and Check carefully ALL of your cable connections.

Yes reinstalled the firmware. Factory reset done. Still getting error. Again replaced the downward vison sensor cable because of the issue with the original cable. When flying drone I can place my hand under the sensor and the drone will go higher as my hand goes higher so I believe the sensor is working. I have checked all downward vision cables and all good. What other cables should I check?

check them ALL if thats the only error you are getting You could have a bad sensor I have not seen the inside of a mini 4 was there any silicone on the connections that needed to be removed? did you replace it. Certainly acts like a loose connection I would look at everyone you can imagine you may have pulled on lol. I am not sure BUT if you replaced the sensor and did not get the new part matched, Maybe, BUT you would be getting a 30210 error ( hardware missmatch)
sounds as if the bottom sensor is fine. That error could be a front sensor Take your Drone out and check the sensors with you remote if one doesnt show red you will know.

Just replaced the sensor ribbon cable not the whole sensor. Yes there was glue on all cable attachments and I put hot glue on from which I removed. I am getting red signals when drone gets to close to things.
