I am waiting on my 2GB RS-MMC card. I plan to boot 2007HE from MMC as well. I have OS 2006 right now but I plan to go to 2007HE. I will backup my 2006 to my PC harddrive just in case I ever decide to go back to OS 2006. I then will reflash my 770 with 2007HE and start from scratch. I plan to install becomeroot, osso-xterm advanced and ssh server and client first. I think I will document my steps because maemowiki seem to outdated or not always the easiest. Using becomeroot is much easier than the directions given by maemowiki on how to become root. I am going to use instructions from weezedog for the speed patch. It is on the first page of this link http://www.internettablettalk.com/fo...sh+speed+patch . He booted directly from MMC so that is what I plan to do. The only thing different I will do is install unzip on my 770 first to avoid transferring the files over. From what I have read you should use the bora ('07) repositories first and treat your 770 like a 800 if you have upgraded to 2007HE.
