As I posted in another Bionic thread, there is a root exploit for JB.
HOWEVER, you have to use
Ubuntu 32bit to do it. It's not all that complicated really. Download Oracles VM VirtualBox (it's free and open source) Link:
Oracle VM VirtualBox. Install that and create a new machine. You'll want to snag the Ubuntu 32bit Live image as well, link:
Download Ubuntu Desktop .. note, this is an ISO image, you'll need appropriate software to mount an ISO to a virtual drive, I would suggest UltraISO link:
Ultraiso Download Page (this is a paid app, but for the purpose of rooting, you can install and use). I would assume that you've already downloaded the Motorola drivers for Windows, seeing that most of us didn't wait for the OTA and did a manual install. If you didn't, you can snag those here, link:
Motorola Windows Drivers. (for those Mac users, link:
Motorola Mac drivers)
Ok, so you've got all the downloads you need now.. everything is installed. Now you want to head over to droidrzr.com and follow the instructions in this thread:
[ROOT] Motoshare 2: Old Bug, New Exploit --
it is very important that you follow the instructions, failure to do so will result in an unsucessful attempt to root. No, you will not brick your phone, well at least I can't see how you would using this method.. you're not doing anything that would cause the phone to brick. So worst case, it would just fail to root. However, a disclaimer must be made, cause there are people that don't read, don't follow instructions very well either; I am not responsible for your device. I am not responsible for your inability to read and follow instructions correctly. If you fail to root or damage your phone in some mysterious manner, you are to blame. Not I, not the authors of posts that clearly give instruction, not Dan who wrote the exploit, nor anyone that has tested the exploit to find it working. Use are your own risk.
