RBS850 Satellites bricked after downgrading from 4.6.7.5

Question

I installed 4.6.7.5 but was having issues with dropped connections and occasional satellite reboots. &nbsp;I downloaded 4.6.3.16 from the support page and manually downgraded the satellites followed by the router. &nbsp;There wasn't any indication that the downgrade failed on the satellites. &nbsp;Once the router restarted, I loaded a backup of my config from before the 4.6.7.5 upgrade and it seems to be working fine. &nbsp;The satellites, however, all appear to be stuck in a reboot loop. &nbsp;They power up, but the LED continually flashes white. &nbsp;The sync button does nothing, a factory reset did not change things. &nbsp;Is there anything else I can try?

Try hardwiring them into the router and leave them for a few minutes. then try syncing them hardwired.&nbsp;
