How to downgrade GPS Here 4 firmware version

Hello everyone,

I was using GPS HERE4 dronecan setup, It was working fine with older firmware version.

Then I tried firmware update for GPS from version 1.3 to 1.12, post firmware update, When I connect to mission planner, I’m getting prearm failsafe : GPS1 failing Configuration check

I don’t know what is the cause for this,
Can anyone help me in this matter
Note: I’m using arduplane version 4.4.4 stable.

And is there any method to downgrade the firmware version for GPS via mission planner or other sources

Thanks
Kiran
