Hi,The following procedure has worked for me in downgrading the RC controller firmware.

The DJI GO application can be used to easily downgrade the Spark remote controller firmware. Follow these steps to downgrade the firmware:

1) Charge the remote controller until it’s at least 50% charged.

2) Connect an OTG cable 1 between the micro USB port on the bottom of the remote controller and the port on your mobile device (or connect the two via Wi-Fi).

Note: Your Spark should be powered off (so it doesn’t connect to the remote controller).

3) Start DJI GO. If DJI GO displays the camera view, click the “DJI” logo at the top, left of the screen to return to the DJI GO welcome screen.

4) Tap and hold the menu button at the top, right of DJI GO welcome screen for at least 5 seconds. When you release your finger, you should see the dark gray “Select firmware version” screen appear.

5) Select the firmware version you’d like to install from the list and tap “Firmware Refresh” to install the firmware.

Thanks for sharing my instructions! More details can be found in the full thread here.

Great

I m glad it finally worked for you.
And I don’t understand how it didn’t worked with your android with wifi only.

Even though I  downgraded the  RC Fw , the jumpy  action on the SPARK is still  active. Luckily my temporary solution for manual landing with the parameter hack works for the time being.

But after downgrading the RC and AC firmware all the bugs like jumping and connectivity issues are gone.
Dji go is updated
Ac and rc are on previous firmware right now.
And I am using wifi, not otg.

i have no clue...mine still stays the same with jumpy SPARK...  My Wifi works very well for long distance @5.8GHz .  But the issue comes only during landing when it jumps  similar to hoping. !!I think my SPARK likes to jump around !!
