Lost FCC-Mode with firmware

Hello all,

my first post here, so I am not sure about forum section. Tried to find solution here, but without success.

I was using a M2 zoom with 01.00.0510 when I thought trying the new advertized features of increased FCC-range and also try latest firmware.

So I upgraded from 01.00.0510 to 01.00.0670, used the fcc+signal boost patch which both seemed to work.
After connecting to my drone and checking on signal strength it showed -108 dB where it showed >-90 dB before.
Looks like FCC mode is not working anymore there.

So I downgraded to 01.00.0510 again und patched FCC-mode, but it still shows -108 dB.

I want to go back to strong signal which was my original reason to use NLD.

How can I do that?

Check bird map fcc not available

Actually according to birdmap mavic 2 should be FCC-compatible with all FW-versions.

Also I did some more research. There is a description how to tell if I run FCC or CE-mode here:

https://greyarro.ws/t/how-to-tell-if-you-are-in-ce-or-fcc-power-mode-using-go4/3315

So if the thin line is above -90 db at about -88 you are running FCC-mode, -92 db something means CE-mode. Is this a correct way to tell?

I am using the latest firmware with Ce version M2Z,  and have  NLD...    FCC and Boost.

in Fcc thin line over 90db means ur in Fcc

You need to apply the mod by NLD again after you update to .670

i keep getting deployment failed, reboot device and try again

have tried reflashing firmware but still cant get the fcc mode to deploy
