Barely a week after we got a glimpse of the next installment of the Android smartphone and tablet OS 4.3 Jelly Bean, some folks at XDA developers have been working on it and now an elite developer known as +Chainfire says he has managed to root it. Google has not rolled out Android 4.3 Jelly Bean yet – in fact the only phone with this operating system is the Google Play Edition Samsung Galaxy S4. On a side note, you can install the Android 4.3 Jelly Bean system on your Samsung Galaxy S4 as I wrote in this guide, but there is no guarantee it will work though.
Back to the story, Chainfire says that he has managed to adapt his SuperSU root application for Android 4.2 and has worked flawlessly on the Google Play Edition Samsung Galaxy S4 which runs Android version 4.3 (JWR66N.S005.130625) that leaked a couple of days ago. In a detailed explanation on Google+, Chainfire posts that the ‘protections’ on Android the phone’s system may be Samsung’s or plainly Android’s, but to root the system it takes ‘quite a few mods to the SuperSU’.
It remains to be seen if all of the protections that have been circumvented have been Samsung’s doing (as is normal for Samsung pre-release leaked firmwares), or if some of them are actually normal for Android 4.3.
For example, Android processes have their binding set of capabilities 0’d out. I’ve not personally seen that before on other firmwares, so I’m not sure if that’s Samsung’s doing or something 4.3. It prevents processes from performing certain actions – evenif the process manages to execute code as root user – like mounting the system read/write. Just to be clear, this root does not suffer from this issue.
If all the features in the rooted Android 4.3 Jelly Bean are fully operational, users with any Samsung Galaxy S4 could install the leaked Android 4.3 Jelly Bean ROM on their devices and have it running with no hitches.
Note that if you are going to install the ROM, you must understand that results re never guaranteed. You will void your warranty and you could brick your phone even if you do everything right. Android 4.3 Jelly Bean is not yet official and from the look of things, Google may not make a lot of fuss about it especially since it has only a handful of improvements from Android 4.2.2 Jelly Bean. Rumor has it that Google may be releasing Android 5.0 Key Lime Pie as early as August this year and it is expected to put an end to Android’s fragmentation.
