EDIT: do you need/want a guide on how to update the firmware etc? Let me know what you're after I'll try to explain it the best I can
I know how to update the firmware (by copying the update.zip to the root of an sd card etc...)
What I don't know how to do is update the kernel without using easy tools.... How do I go about doing this, using adb?
I'm guessing it's pretty straightforward?
Alternatively, I would think I could use the last "easy tools" release to do it (just rename/replace the old kernel file with the new one?) Would that work?
