Stuck at "cp: not found". Downloaded busy box from the marketplace, opened it. It said "Status: Waiting...", so I hit install. Now it says "Status: Done!" Below that it says "Your phone is rooted. Busybox was found here: /system/xbin". Seems like it's installed? But still getting "cp: not found"
Edit: Uninstalled busybox, redownloaded it, opened it and hit install again, and "cp" was working fine, not sure what the problem was the first time. Got it all working and sideloading with ease.
