I've messed up the Omega2 kernel (tried to move /etc and /usr to a microSD! 
). Is there a way to restore it to factory setting? I tried to reinstall the firmware by clicking reset and power and getting the image from a USB (selection 2 at the prompt) but I got the following error ...
Any help will be greatly appreciated.
Thanks,
Anupam
