Oops, sorry. There were a few things that I should have suggested for you to do as insurance.
If you have a copy of the original (unmodified) boot.img (3.1 or 3.2) you can simply fastboot boot that. If you have a copy of the recovery.img, that can be modded to add ADB. What do you have for images? Does a TWRP exist?
In any case, the first thing to do is see if you really lost ADB. On my Poke3 it goes to the big seashell and the dots that count up. If you didn't screw things up too badly you should still have ADB even if the Android home screen never shows up.
Code:
C:\>adb shell
$ su
# stop
# cd /data/adb/modules/Whatever
-- delete whatever is necessary --
# reboot
