Can u post detailed instructions on how you did that? Not a comp guy bit would love for this thing to get stable.
Just download that file (I used the one from ckolvas' repository, but they should be the same - I posted the link earlier too). Then go to your Avalon page and System > Backup / Flash Firmware. At the bottom is the option to flash a new firmware image. Make sure you keep your old settings (checkbox above the "Choose File" button). Then hit "Choose File" and point it to where you saved the binary, then accept that and click "Flash Image." Voila'. Then reboot. You should be running 20131229 and cgminer 3.9.0 from now on. Enjoy!
