PC with Windows 7/64 Ultimate fully updated, 32GB Ram, Intel i7 2.4ghz, no computer issues with updating firmware on at least 6 other devices via USB.  

New DJI Mavic 2 Pro with Smart Controller January 4, 2020.

  

1) Downloaded and installed DJI Assistant 2 for Mavic, latest version, connected and updated the Mavic   2 Pro to latest firmware no issues.

2) Could not connect Smart Controller with DJI Assistant 2 for Mavic via USB, finally connected after multiple attempts, the download failed about 7-8 times and then finally installed. The firmware was unfortunately flawed in that parts were not translated from Chinese. (I have the v01.00.0650 with PAD V00.00.09.80 release keys line) It appears DJI pulled the firmware update down and quickly issued a fixed update with the same version number but with PAD V00.00.09.84 release keys.

3)  After this update the Smart Controller will no longer connect after hours of trying in order to refresh the firmware.

4) Have tried all the possible solutions I could find on this forum and others with no luck including:

  

a) Factory reset (does not reset to the originally installed version 01.00.0530?, saves all other settings as well, so no sure what a factory reset even does…..)

  

b) Uninstall and re-install DJI Assistant 2 for Mavic 3X

  

c) Manually install DJI drivers.

  

d) Enable developer options and manually select MTP file transfer USB setting, with USB debugging on and off.

  

e) Logging out of DJI Assistant 2 for Mavic, then logging back in.

  

f) Wifi and Wlan say I have the current version and will not connect to refresh.

  

g) Tried a couple of different USB C cables. No luck.

  

h) Tried on my son’s Macbook – no connection there either.

  

i) When connected the Smart Controller shows up in my computer as rm500, Portable Media Player, and in Device Manager under portable devices as rm500 with no exclamation marks, status: This device is working properly. Driver details C:\Windows\system32\DRIVERS\winUSB.sys (others listed but I believe this is the critical one)

So Windows is seeing the smart controller on USB and I can access the folders on the internal storage and SD card. DJI Assistant 2 for Mavic is working fine for the Mavic 2 Pro aircraft.

  

I think my Smart Controller is toasted, any other suggestions before I send the whole lot back?

Called DJI support and said I was having issues with my Smart Controller - tech asked what mobile device I was using with my M2Pro - it got even worse after that......

  

Just an update if anyone is still watching.

I ended up returning my Mavic 2 Pro and Smart Controller to the retailer where it was purchased (Vistek, Canada) Their product specialist did some further evaluations of the problem and determined that the USB port in my smart controller was defective.

That would definitely explain the flaky connection problems I was having with the Smart Controller.

The drone and controller are being returned to DJI and my new M2Pro and Smart Controller are scheduled to arrive tomorrow.

(Wondering if there was a bad batch of USB ports installed on these devices as so many people seemed to be having the same problem)

If the port was bad could you not charge it? I have the same problem with assistant 2 not recognizing the smart controller but the usb-c port is fully functioning and able to send/receive files along with charging. The problem is with the software(DJI’s application) and not the hardware. It still bugs the absolute sht out of me, in just glad I can update through wifi.

Yes it did charge OK, I believe the problem was with the data transmission side of the port (The store where I purchased it did the testing and deemed it was defective.)

Mine was replaced under warranty and the new one charges and updated just fine (I have done one firmware update but haven't done the latest one yet as it only seems to add functionality for other models that I don't have and have no plans on acquiring)

Great post, i was having the same issue as well and havent had any luck resolving the problem. Might have to just sent it back as well. Thanks for the post.

I also have the same issue with the smart controller. It charges. But no connection with ass. 2., which the M2Pro does fine, and updates. No more answers from DJI...!!!

My replacement connected and updated fine with DJI Assistant, the original was defective.

The last two updates I just did directly through the Smart Controller over wifi. I don't believe this was an option for the earliest firmware upgrade, but it seems to work fine now so I have not used DJI Assistant recently.

Might be worth it to try the wifi option if nothing else is working.
