Sub ghz external module suddenly not selectable

Hello there.

I have the flipper for a while now and have been enjoying it. I’ve collected a few external modules but I’ve run into a problem that makes me think something in the flipper has broken. I have 3 mayhem hat modules. 2 times the 1.4 models and a 2.0 model. I’ve been using the blue CC1101 sub ghz module on all of them. For this I select the external in the Sub Ghz menu and off we go. But now I cannot select the external anymore. I’ve switched between the mayhem hats and also replaced the CC1101 module but all configurations that worked before don’t anymore.
Have I broken the flipper or are there still other things I can try to revive?

What I’ve done sofar:

Switch the mayhem hat
Switch the antenna module
Reboot (left press and back)
Factory reset in the menu.

What else is there to try or what else to trouble shoot and find a definite cause?

Thanks in advance for your time and input.

If you have a way to test the power going to it I would give that a try. Some modules pull from the 3v GPIO port and others pull from the 5V GPIO port. If you have one of the versions that uses 5V you may have to enable 5V. It’s possible you toggled that off somehow.
