Proxmark3 Easy first timer problems (bricked already?)

Hey all. I was setting up the PM3 using the instructions here.

Ran the following:

pm3 ~/proxmark3$ ./pm3-flash-all
[!] Using pm3-flash-all on an oudated bootloader, use pm3-flash-bootrom first!

so I ran:

pm3 ~/proxmark3$ ./pm3-flash-bootrom

and now I have a seemingly bricked proxmark3 as it no longer detects on COM3. What are my options here? Do I have to mess with JTAG?

pm3 ~/proxmark3$ ./pm3-flash-all
[=] Waiting for Proxmark3 to appear...

I figured out how to fix this from various sources. I unplugged the Proxmark3, held the button down and plugged it back in. After about 5 seconds Windows detected it, and I was able to run ./pm3-flash-bottom. Then unplugged it again, held down the button for 5 seconds and then ./pm3-flash-all. Finally ./pm3 and all is good
