I have a pair of radion pros that were running 1.6.10. I just ran the firmware update on one of them to 1.7.6 successfully, kicked off the second one and it hung. I let it go for about 30 minutes and finally refreshed the page. Now I cannot connect to the second radion. Reeflink won't find it wirelessly and I've tried connecting via usb. Pulled power plug several times, the light on top goes to a flashing red/white almost immediately. What do I do here?
