Had this issues with mine also. Pushed a bad framwork-res file and cause it to boot loop. Couldn't get adb working to push files. I was able to use lgnpst to see the phone and was able to flash the tot file from jcase's root method.

While phone it boot looping open up device manager on your computer and see if you see a com port for the phone under the ports section. If it's there or not depends on if you left diag mode enabled after you rooted.

If diab mode is disabled and you don't have a com port showing it won't work and not sure of any other method to push a framework-res to phone
