Nohands, you can download a 200.6 version of Unleashed code for R500 or R600, which ever is your
Master AP model from our Support site.
From a workstation on your Unleashed WLAN, so you you can get to the Admin GUI, try a Manual upgradeand point to your Master AP model image.
Disclaimer: I can't remember if original 200.0 Unleashed has the Manual upgrade option... =:^(
If worse comes to worst, you might need to document your WLAN configurations, etc and upgrade an AP bya direct connect to your PC and factory default the AP to 192.168.0.1, onto the current Unleashed release, and create the network again, then add the remaining R500/R600s (that will auto-upgrade when recognized).
