I have looked through the forum and could not find a relevant solution for this. This is not an "M" unit. I followed the firmware procedure as described at http://wiki.openwrt.org/toh/ubiquiti/bullet and have found the following  (below). I looked for history locations for an older FW version and the latest I could find was from 11/2014 (?) and it produces the same result. I have successfully loaded the DD versions on another unit. This is my alternate test piece and would like to test the OWrt versions. Any assistance would be appreciated.

71xx firmware will not run on a 2316 processor.  It would take one of the ubnt2 versions from atheros/generic.  Suggest trying this one first:
http://downloads.openwrt.org/attitude_a … uashfs.bin

Being a redboot bootloader, it should be compatible with ap51-flash, which bypasses the factory firmware's version checker.

Thank you for the prompt reply;
Both the onboard firmware updater and the SSH returned fail.

Thank you for the thought. It seems like a nice unit on it's own and I would hate to scrap it so early in play. I have not had a problem with OpenWRT loads in the past. Should I go to the serial connection for now? This would make updates in the field a bit trouble for the un-initiated. Are there any other options available?
