I cannot seem to get step #8 working.
I would really love to be able to make a full backup, system settings and all. To do that, I gather I will need "Nandroid", and thus this recovery image. I don't think I have any further need of being root. Also, I'm quite happy with the stock K4 firmware, so I don't plan to try the custom Galax* roms (which I believe are built on an earlier firmware).
No matter what I do, fastboot times out and does a normal startup, while my terminal still says "<waiting for device>".
My Device Manager (while doing all sorts of plinky-plonky sounds) gets an entry for "Other devices: Android 1.0", but no matter what driver I feed it, it ends up saying "There was a problem installing this hardware: Samsung Galaxy Composite ADB Interface".
The entry is still there, but it has a

symbol on it. I have no problems mounting and accessing the sdcards, so something
is working.
I have installed NPS, Eclipse, and the SDK; I really think it's the drivers. What more can I try, are there alternative drivers I could try?
