i am unable to Flash the old ZF7982s that ive replaced in my network back to the standalone firmware they are currently on
126.96.36.199.354 and i want to use them as standalone elsewhere ive tried to put these firmwares on zf7982_188.8.131.52.17.BL7 and zf7982_184.108.40.206.15.BL7 but they dont work either via web interface or via CLI & TFTP the error i get is
net_get_flash: **Err:Upgrade/Downgrade from FSI to UI is not allowed.**
AIS cleanup : Completed
** AP Image Signing : Upgrade/Downgrade from FSI to UI is not allowed.**
**fw(15364) : Unknown
from reading around it looks like i may first have to get them onto a SmartZone 3.4 or 3.5 Firmware before i can flash them with the Standalone Firmware would this be correct and if so where could i get a 3.4 /3.5 AP SZ Firmware?
I just quite like to use one or two of these at home as they are still pretty good APs seems a shame just to have them as paperweights.
