Hi all. Last week, I tried to enable r&d mode on my 770 and succeeded. Then, tried to modify the gainroot file in order to avoid the r&d mode control but ever since then, always get a "/bin/sh: illegal option -" error when I run the "sudo gainroot" command.

Guess this is due to the fact that I added the comments # using a windows editor; my opinion is that the editor itself converted the original CR charachter contained in the gainroot in CR+LF...

Anyway, bedides what the cause was, is there any way now to recover my system gaining root privileges or do I have to reflash it?? It all works ok but the gainroot command, althogh I am in r&d mode...
I also tried "sudo su -u root" but it wouldn't accept a password (tried "rootme")

Thanks to all!
