MK1 GF with Modern grip and extension.

[target]

Just finished cleaning and changing out a spring and now the red light is flashing on the black box and nothing responds in the configuration tool. Tried several things to include deleting the config tool, nada. Any help would be appreciated.

Check the grip to extension and extension to base connections and reseat them.

[target]

Done, no result.

Check the wires inside the base then, it's a connection issue. If everything is fine eliminate the extension and try again with the grip directly on the base.

Done, no result. I've been at this for half of the afternoon. 7PM here now. Checked all the connections, except for the one that goes into the base, can't see that one. Have had the grip with the extension on, without it on, changed the usb port, unplugged it, plugged it back in, hit default in the Devconfig to go back to factory specs, deleted the devconfig altogether.
It happened right after It had been working. I changed some springs and then it wasn't working, have had the base apart several times just to check the connections since then, I noticed there's a red light on on one of the boards when I decided to look at the inside while it was plugged in, but I figured that could be normal since I haven't had to run down a problem like this before.
I also noted that while I was running through some settings in the Devconfig app the blue light began flashing rapidly.

The red light inside the base is alright.
Are there any axes or buttons recognized in the tester?

[target]

No, none.

[fallout9]

If only the pitch and roll axes are moving in the tester then it's a connection issue between base and grip. If no axes moving then it's either inside the base or between the base and Black Box.
Post a screenshot with VKBDevCfg.

Which panel do you want to see?

[fallout9]

Just want to see the device list, make sure it's the right firmware.

Found the problem. One of the contacts was stuck in low position. Never crossed my mind since I had cleaned and sprayed them with silicone not long ago. But there you have it.

Good to hear, congrats!
