chux - i have a download in my sig that has all of the files you need and the latest iso loader with the channel installer and a how to step by step on it all for a pretty basic install from scratch.(I didnt make any of them so no credit goes my way , just made a nice easy zip with everything you need in one - and im trying to keep it up to date as things change )
You can give it a go if you like - let me know if theres anything confusing and ill change it, but a few have tried and no one ran into any issues.
Granted this is an install from scratch , u may have some strange things because u have some bits done already , but its a learning process - worth a try if you want.
There is a folder on the SD card side of the files that has apps in it and in there an ISO folder with a boot.dol and bootOriginal.dol ... the bootOriginal.dol file is the initial beta release by Waninkado so if the boot.dol file doesnt work try renaming that one and replace it with the Original one and see how you go.
let me know if you figure it all out.
