Hi,
I have rooted my nexus one, Samsung galaxy apollo, micromax canvas HD and my nexus 7. I guess that will be able to satisfy the need for experience.
The rooting experience I have is for Android version 2.1 to Android version 4.4
My freelance timings are between 10 PM IST to 3 AM IST.
Feel free to message me for further discussion.
Regards,
