Problem with openlrs, how to test hoperf module?

Hi everyone. I'm having some trouble with my transmitter module for radio control. I've made a video showing what's it's doing, and posted this around quite a bit. Haven't been able to find answers
Here shows what it's doing. Basically after flashing it it just flashed the warning light, and is otherwise dead.

I'm not sure what the problem could be. So asking here as well, haven't been able to get anywhere on other forums. The module was working fine before I re-flashed it, so thinking I might have killed it with ESD because I cant tell what else could have gone wrong.

How could I test if the RF part is working?

If it's busted I will try replacing it with this or this
