Android 5.0 is a big step up in security with its tweaked implementation of SELinux. Chainfire managed to get root on Lollipop shortly after it was released, of course, but the process has been a little more messy. There are also a fair number of root apps that are broken on Android 5.0. The newest build of SuperSU from Chainfire might fix many of those issues, though.
Android 5.0 is a new age for rooting on Android. Google's latest security enhancements require more hackery to circumvent and the Nexus 9's 64-bit software complicates matters even further. Still, after just a few hours, Chainfire has updated SuperSU to work on the Nexus 9, but there are a few extra steps.
Technically the Developer Preview builds of Android L that Google issued are meant only for, well, developers. But of course a ton of regular users have downloaded them to try out Lollipop, and those users tend to be the same ones that like to use root apps. The updated Android 5.0 preview builds for the Nexus 5 and Nexus 7 2013 issued yesterday broke the existing root functions, so SuperSU developer Chainfire issued a quick fix.
The SuperSU root permissions manager is probably one of the most widely-distributed power user tools on Android at this point, though it won't be breaking the Top Ten lists in the Play Store any time soon. Developer Chainfire has issued an update to version 2.13, which includes a huge list of additional and adjusted features. As far as usability is concerned, the biggest change is probably the fact that the app is now available on the Amazon Appstore.
Two weeks ago developer Chainfire rooted the international GSM-LTE version of the Galaxy S5. These things take time, but apparently not much of it. Barely two weeks later, the modder is back after having rooted six additional variants just in time for the official commercial launch. These include the T-Mobile, US Cellular, and MetroPCS models, the International Exynos option, and some shipped to various other parts of the Western Hemisphere.
That was fast. Despite the fact that the Galaxy S5 won't be released for another two weeks, well-known developer and modder Chainfire has already rooted the phone. Well, at least one of the Galaxy S5s (S Fives? Galaxies S5? whatever), specifically the SM-G900F model, which seems to be the international GSM-LTE version. The root method will probably work with at least some regional and carrier variants.
To get root privileges, check out this XDA-Developers post for Chainfire's latest version of the CF-Auto-Root tool, flashable via a PC with Samsung's ODIN tool.
OTA updates are usually a good thing, but first impressions can be misleading. The just leaked Android 4.4 KitKat build for the Galaxy S4 seems good, but some behind-the-scenes changes broke SuperSU, making root access difficult. Ever the go-getter, Chainfire already has it sorted out.
The new flashable ZIP file is available from Chainfire's site – version number 1.89. CF-Auto-Root has also been updated to include the new SuperSU. This has been successfully tested with the leaked ROM on the GT-i9505, but should also be fine on other devices you need to get root on.
If you're a root user, listen up. Chainfire updated SuperSU to v1.69 as of last night, which fixes two exploits that could allow an attacker to leverage root privileges without first prompting the user. Probably nothing to get overly anxious about, but it's definitely a good idea to make sure you're running the latest. Details of these exploits will be released next Monday, so you'll want to grab the update before then.
These days, it seems like everybody is trying to make Android more secure. As usual, rooting and modding are often casualties of this effort. Just over a month ago Android 4.3 broke the existing model for root, forcing updates to existing methods, and now Samsung is rolling out updated Android 4.2.2 firmwares for the Galaxy S 4 which fully enable the company's heavily secured KNOX environment. Fortunately, Chainfire is already on top of it and has updated his popular root software, SuperSU, to be compatible with the new system.
