Missing Modules: CYRF6939

I've got a missing module: cyrf6939

My situation:
Devo7E
Range modded
Swivel antenna modded
3x2 switch modded
A7105 modded

The mods has all been succesfull, and has been flying a couple of months
The last couple of days, I've been flying indoors with my Hubsan X4 FPV, bad weather in Denmark

And today I got this message saying that the CYRF module are missing. I actually started by, being only periodic, but now it's on every restart of the Devo7E

Where do I start troubleshoot that?

The battery has been changed and are full
Tried to re-upgrade with debug-devo7e-v4.0.1-ef0d76d and remove all files and start with "fresh" files.
Tried to remove the ; comment for the CYRF module in the Hardware.ini with no luck

I can still fly with the Hubsan copter if I ENTER the Missing Module: Message

Do I have to get a new WK-21201 RF ?

Nevermind

Re-soldered the damn ground leg on the module, seems like it was a cold sucker :-/

EDIT: Didn't fix it

To be sure, When I get my new CYRF module.

The right thing to do is to remove the old CYRF module?
But should I connect the CSN to TSK, when my A7105 is connected to TMS?
