(from ogra's http://paste.ubuntu.com/10501535/)

• get the IP of the device with ifconfig
• android-gadget-service enable ssh
• use phablet-shell once so your ssh key gets copied in place
• log out from phablet-shell or adb
• scp the android-tools-adbd package in place

• ssh phablet@<ip of the phone>

• sudo mount -o remount,rw /
• sudo dpkg -i /path/to/adbd.deb
• sudo mount -o remount,ro /
• sudo reboot

now check that:

• adb root is a nop-op
• adb shell only works with screen unlocked (adb on the PC should print "error: closed"
• adb push and pull only work with unlocked screen
• adb reboot and adb reboot-recovery work in any case (locked and unlocked screen)
