adb help?

[actngrezy]

I have had adb set up for sometime now.
I always do a system format,data,cache and boot through adb
now I can hit adb shell and this will pop up underneath (in recovery)
/#
If i type su it says not found sh or something to that nature
then I try to mount by mount -o ..... and it will say mount not found

So i will go into the recovery and mount system and the same thing happends. I try to pull or push the phoen.apk
adb pull Phone.apk /system/app
It says adb not found

But i run bbv1 so i ran petes zipalign script and that worked fine so i dont understand whats going on?


Now if I do this when the phone is booted up (not in recovery) the su works adb shell works I tyoe the mount command and it say basically repeats the command back to me but doesnt say failed or not found or anything. But if i try to push or pull once again it will say not foudn for anythign i do .
Can anyone help? and by the way the apk i try to push to the phoen is in my tools folder

2nd shot is when in recovery and i tried to chmod 755 the system/bin to see if that helped but it says adb not found and su not found
