never mind, i missed a step. followed the guide here: xda-developers - View Single Post - Quick rooter for stock FroYo systems + 2.6.34 kernel
. i hadn't done step 4, and now have root.
can someone explain what is going on in step 4? i know the 2nd part is flashing the recovery rom to amon's custom recovery image, but what does the first boot.img do? can a custom recovery image not be using without the custom boot image?
