(others have commented same issue in this thread Jelly Bean)
I am unable to root after JB OTA Update to 4.1.1
Process followed by results below:
1. Download and extract the entire zip file. (http://vulnfactory.org/public/motofail2go_windows.zip)
Download this: http://www.aosp.us/wp-content/files/Root.zip
Inside the folders you will find su.apk and superuser.apk. Copy and replace the ones that came in the original post with these two apks here.
2. Ensure your device is connected via USB and that you have installed the latest ADB drivers from Motorola.
3. Double-click "run.bat" and FOLLOW THE INSTRUCTIONS. The exploit will ask you to press a button combination at one point.
"Volume Up + Power simultaneously" does not appear to "trigger bugreport"
"vibration" is just the ringer volume increasing.
Holding VolumeUp+Power for 5/10/15-seconds has same effect (no distinct vibration noticed).
Press any key to ... (phone reboots)
No Superuser.apk installed and effetivley no root effect that I can see.
I have also attempted using the original motofail2go_windows.zip without the changed Superuser.apk & SU-file (same results as illustrated above).
Any advice would be appreciated,
I think the solution for my problem is here;
