Hi. I flashed a T300 to use the Unleashed firmware and now I would to convert this back to the original firmware but cant see an option within the unleashed GUI to do this. Is this possible?
Yes, this is possible. First you have to set it to factory default settings. Second in the Setup Wizard after connecting to the configure.me SSID in the wizard is an option for show ap info -> choose Upgrade, there you choose the standalone image, flash the device and reboot -> Done
Documented in KBA-5193: Can I convert an Unleashed AP to ZoneFlex Standalone/Controller managed mode?
