Drone wont connect

so I tried changing my home app from QGC to here launcher and that worked but when i tried connecting to my drone using Solex it didn’t connect, now it wont even connect on QGC. led1 is not lit on the air unit but the Herelink shows its paired. I read on here that I should re flash my cube? I am not sure how to do that. this is my first drone with Pixhawk so I would appreciate any help

Please try to reflash the firmware on air unit

i got it figured out lastnight. it was a computer problem not being able to run the flasher.
