Sign [Q] CWM or ODIN recognize external sd?

I installed the wrong ROM on my phone and never made a backup. I have the S4 mini intl GT-I9195, It just bootloops now. For some reason I'm having issues pushing a rom to the phone with ADB while in CWM. I cant get it to recognize via "adb devices" command, but I just remembered I can install an external SD card into this phone.

Will CWM or ODIN recognize the external SD card and install a ROM? I can still get into recovery so if I can put a rom on the external I'll try that instead. I just dont have one on me right now and dont want to buy one if I dont have to.

Thank you!

EDIT: It works, just in case anyone was wondering..
