Dear Dji

I have a few questions as follows:

1. Why is the DJI Assistant 2 (Consumer Drones Series) V2.1.16 application that I just installed, can't display the firmware list from the previous firmware

2. What is the reason, why is the DJI Assistant 2 (Consumer Drones Series) V2.1.16 application currently unable to downgrade the firmware

My question above is related to the fact that I currently have a problem where the DJI Mini 2 drone is currently often losing signal after upgrading to firmware version 01.06.0200 (RC to 04.11.0200), I will try to downgrade to the previous version, to see if as a result of the firmware upgrade or not

thank you for your answers

Hi, fans7586fea3. Thank you for uploading the video. Please try the following steps below to troubleshoot this issue:

• Please adjust the remote controller antenna position and have the wide surface of the device face the aircraft to ensure normal signal transmission.

• Ensure that the current flight environment signal is good; it is recommended to replace the flight environment test with a good signal. If the replacement flight environment problem is solved, it can be judged that it is caused by environmental factors.

Hi Dji Gamora,

I just refresh firmware and also replace flexy cable (phone to RC), the results are pretty good even though it's not 100% perfect like when I just bought this DJI Mini 2, the results can be seen in the following link (available english subtitle)
