Everything works fine until I get to do sudo adb device
sudo: adb: command not found
But then it seems to work if I use it like: sudo ./adb device
That gives me this
List of devices attached
But when I go to the next step and I do sudo ./adb push su /sdcard/su
failed to copy 'su' to '/sdcard/su': Permission denied
Debugging mode is enabled, I do not know what is missing.
