Config Error:Failed to update IO Firmware

I am getting “Config Error:Failed to update IO Firmware” after flashing Ardupilot V4.2.3 via mission planner and above on my pixhawk cube orange+.I tried booting using safety button,but it did not help.

I am using Here 3+ GPS,all params other than NTF_LED_TYPES have been saved successfully but when I write this param gives me the error :"Set NTF_LED_TYPES Failed.

The GPS is still lighting all the LEDs(purple,yellow,green)

Hello @Uditi , welcome to the community,

Please update to ArduCopter 4.4.3 and retest.

Thanks for replying !
I started with ardupilot 4.4.3 but it gave the same error so went back to previous versions

By now you found that this is not a regression and as such not fixable by using an outdated software version.

That I did, I was just trying out different things, just to see if anything would work because I couldn’t get any solution anywhere.

I have same problem with OrangePlus+ after did more 10 good flight, after day, drone returned that msg and nothing is doing more !
I update new firmware, return to my origin firmware, nothing. I think that is internal error !
