I have done a search and couldn't find anything on this so here I go. I am not extremely new to adb shells and linux operating systems (I successfully installed ydl on my ps3) but I have recently run into an issue on my rooted droid. I am trying to install busybox onto the phone and do the following: $ su # mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system adb push ./busybox /system/sbin When I get to the last step I get "adb: not found". I have attached a screen capture to show where I am at. I'm not quite sure why it is coming up with this and don't really know what to do from here. I have a copy of busybox in the tools folder and on the root of the sd card. Thank you for any help and let me know if you need anymore info.
