Root Android L Developer Preview on Nexus 5 and Nexus 7 2013 [Patched SuperSU]

Page content:

There were rumors that the next version of Android may block system write access making root pretty much useless, however the Android L developer preview that released for Nexus 5 and Nexus 7 2013 yesterday shows no such implementations, but there’s a minor change in rooting script though.

The SuperSU app which we have been successfully using to root our bootloader unlocked devices for a long time now, requires some minor changes to be able to root Android L. Chainfire, the developer of SuperSU app posted a tweet explaining this:

We made the changes suggested by Chainfire into a new flashable .zip file, and it installs fine now. You can grab the modified “SuperSU-v2.00 for Android L.zip” file from the downloads section below and flash it via a custom recovery.

    Thanks for the Zip File! Already flashed TWRP and the boot.img on my N5 before. Flashed your modified SuperSU.zip, reboot, root. Yeah! The most important thing for me: AdFree and Root Browser work as expected, Quick Boot still doesn’t. Other things I still have to test.

    P.S. Sorry to say, but you page is a pain to view on Chrome on my phone. Gets cut resp. covered up by something in the Chainfire Twitter post. Had to boot my desktop in order to read the guide and download the files. 🙂

    After having rooted My Nexus 5 this way, now when I reverted back to 4.4.4 using Unified_Android_Toolkit (http://forum.xda-developers.com/google-nexus-5/orig-development/toolkit-skipsoft-android-toolkit-nexus-t2525026) I can flash a stock google image but after it ‘writes’ system img it gets stuck saying writing though it has completed. if I reboot I will be able to get into the stock image as expected but I always get the error “Failed too many links” from the Unified_Android_Toolkit console. beforehand after flashing a stock image it would complete and reboot the device with no intervention needed from me. is there a way to correct this now?

      Try flashing this SuperSU file from Chainfire’s official site through a custom recovery. Flashing boot.img file isn’t required with this file. (link below) http://download.chainfire.eu/451/SuperSU/UPDATE-SuperSU-v2.01.zip
