I can't install a custom rom on my s6!!

[Android Central Question]

My samsung galaxy S6 I think its bricked but I uninstalled the samsung os because I am used to flashing other devices when you uninstall the os and run an adb command to install a custom rom. Which I did on my S6 but then it wouldn't install any custom rom I try to make it install on the adb. I then saw I was supposed to use odin which I tried but it didn't recognize my device even after installing drivers. So now I dont know what to do. I officially gave up and I need answers please help!
