Question [Q] How can I enable ADB in the ROM from recovery?

I have a Nexus 4 that I just shattered last night. Screen is still visible but is unresponsive to touch. I'd like to be able to control it from my PC but I had ADB turned off before this happened. The buttons still work fine so I can get to the bootloader and recovery just fine. Device shows up on adb devices when in recovery and I can issue commands. I'm just not sure what to do from this point. I tried following this: http://forum.xda-developers.com/show...16&postcount=5 but it didn't work. Doesn't seem like those commands work the same when in recovery.

I'd really appreciate some guidance. Any help is appreciated. Thank you.
