Get Root on Jelly Bean For the Transformer TF700
After the wildfire of development that erupted when Jelly Bean source was released three months ago, OEMs have started stepping up and providing official updates for their devices. Several devices have already been updated, with many more getting firmware leaks. One device that has already gotten the Jelly Bean love is the ASUS Transformer TF700. What’s more, it’s been rooted.
XDA Senior Member hiemanshu has posted a method to root and install a custom recovery on the Transformer TF700 Infinity after it has been updated to Jelly Bean. Most users likely used the Root Keeper application to keep root. However, if you bought the device recently with Jelly Bean already on it, or forgot to use Root Keeper, this will help get you back on track.
First and foremost you’ll need your device unlocked. After that, it’s a matter of downloading the appropriate Jelly Bean ClockworkMod Recovery, flashing it over Fastboot, and then SuperSU via the recovery. It’s a pretty common method, so users shouldn’t have much trouble getting it to work. So far no one has reported any major issues, and the process should take about 10-15 minutes.
