Obstacle avoidance not working and battery problem

I purchased my key here, first downgraded to .200 with DJI Assistant and  Mavic 2 has been downgraded to with NLD to .100 and patched for NFZ. Obstacle avoidance not working and DJI Go say  battery is not connected, fly with caution.
With Windows 7 NLD is not working but with 10 was  connected immediately.

Used NLD in Win8 setting the app to Win7 compatibility. Flawless.

Try reflashing .0100

Here everything works

Mavic 2 Pro on 01.00.0100 with NFZ patch, DJI Go 4.3.14 official, Windows 10. Everything seems to be fine except for the obstacle avoidance. I do not have the battery issue but there's nothing i can do to get any obstacle avoidance anymore.

SOLVED:

Reflashed firmware (which was probably not necessary) and same issue... My firsts flights on this modded firmware were at night though, hence, too dark for sensors. Tried taking off today in the light and, lo and behold, obstacle avoidance functioning as normal.

I remove NFZ is half an hour...but it seems to be stuck.
