Holy wall of text, Batman!
Time for a 'stable' SuperSU update! There have been quite a few beta releases the past few months, with lots of under-the-hood changes, lots of bug fixes, lots of compatibility additions, etc.
Again, a fair amount of work has been done to keep SuperSU operational on the latest AOSP builds, as security-related changes to AOSP are likely to end up in retail L. The changes are quite extensive and a departure from previous strategies to keep SuperSU operational on AOSP. As a side-effect of this, it may ultimately actually increase compatibility for root apps between different Android versions (and be less work for root app devs to support), as if it ends up working well on L, I will back-port these changes down to 4.2. It should be noticed that these patches are already in-use and tested against 4.4.
Cryptic and unspecific, I know. I will write about these things in detail once L is released (any day now?), if I don't have to revert them.
So what are the chances of this working on L at release? If we're lucky, the CF-Auto-Root's for the Nexus devices will work out-of-the-box, but there's no way of knowing yet. There are dozens of things that could still go wrong, in fact, I have some concerns that ultimately we may need to have modified boot.img's to have root at all. We'll see when we'll see!
One thing I can tell you is that OTA survival mode will be very unlikely to work between 4.4 and L, at least initially.
Architecture specific binaries
SuperSU now comes with architecture specific binaries for: arm (v5), arm-v7a, arm64 (v8a), x86, x64, mips and mips64. The 64-bit variants are officially supported from L onward, so obviously they have not been tested on production devices yet.
CF-Auto-Root currently still always installs the arm (v5) binaries. "su -h" will display the specific version you are using.
Amazon now distributes SuperSU as well, but their vetting process is more extensive and much slower than Play, so expect Amazon releases to generally lag behind Play releases.
Aside from adding the CF-Auto-Root for it to my extensive list, this version of SuperSU brings some minor but much-needed improvements that just make it behave significantly better.
SuperSU now cleans up leftover packages from the root list at boot (if re-authentication is enabled). While this really is a minor thing, I want to point it out explicitly because on some devices and Android versions, if you move root apps to the SD card, this cleanup will be performed before Android has scanned the SD card for the apps. So from the perspective of SuperSU, these apps do not exist, get removed from the root list, and well re-request root access when run.
A proper solution is still under investigation, and it does not happen for me on any of my 4.4 devices. Either way, if you find apps are losing root access on reboot, a work-around for now is turning off the 're-authentication' feature. Please do report this and your device and firmware details to the SuperSU threads on XDA if it happens to you.
The latest (stable) flashable ZIP is available from http://download.chainfire.eu/supersu as always. All CF-Auto-Roots have already been updated.
I will update Play tomorrow, assuming no showstoppers are found by those flashing the ZIPs, which will probably be a staged rollout. So best-case scenario, everyone should be updated come Monday.

Special thanks to all the beta testers
For the modders and exploiters amongst you, I have added some documentation to the update-binary script. It's not complete yet, and there are a number of changes and improvements I still want to make, but I'm sure it's more helpful now than it was before.
There have been a few changes to the CF-Auto-Root installer as well. One noteworthy one is that in preparation for L having encryption enabled by default, it no longer touches /data. This is both good and bad.
The good is that it doesn't need to know your decryption key, the process remains automatic, and encrypted phones are no longer wiped on usage of CF-Auto-Root.
The bad is that this means some /data cleanup code is run on first boot after rooting, which may trigger a (one) reboot in the process. I do not expect bootloops because of this, it works fine on all the devices I have tested it on, but you never know.
Additionally, because CF-Auto-Root cannot distinguish between a garbage and an encrypted partition, it no longer fixes OEM unlock issues. On several fastboot based devices, the OEM unlock command, instead of formatting /data and /cache, wipes them. Android will not automatically re-format them anymore (used to in 2.x days), which means that your device will forever bootloop until you manually format /data and /cache (which CF-Auto-Root did for you automatically in the past).
Last but not least, some changes have been made to allow the progress to be visible on some new Qualcomm based devices. While I would normally not waste words on something as trivial as this, I would like to point out that these devices no longer support fbdev to put content on screen, but instead use something called Qualcomm overlay. Nothing basically wrong with that either, aside from the absolutely horrid fact that the interface to this changes between different kernels in a completely incompatible way, pretty much requiring a userspace program to use the exact right version of kernel headers to do something as basic as putting anything onscreen. Making a non-kernel specific binary that support a wide range of devices is thus now nigh impossible unless some very ugly code and errorprone methods are employed. As such, I expect that ultimately there will be no visual progress for CF-Auto-Root anymore on Qualcomm based devices, as I certainly can't be bothered keeping track of these shenanigans.

When will you update play store app?
"I will update Play tomorrow, assuming no showstoppers are found by those flashing the ZIPs, which will probably be a staged rollout. So best-case scenario, everyone should be updated come Monday."
Excuse me, i skipped this xD
+Chainfire, you could probably use setup_fs (system/extras/ext4_utils/setup_fs.c) to fix at least some of the OEM unlock issues, if not all.
This was last used by Google for Galaxy Nexus, and does work on Sony devices too (we're using it on all 2012+ devices supported by CM currently, which is all devices including and after Xperia T).
+Chirayu Desai thanks, nice find. It's only a handful of devices suffering from this though, not exactly a priority.
+Chainfire.. Keep up the epic work, man! Thanks again for all you do
Thanks for your hard work!
Thank you for all the work, updates and detailed info!
thx a lot
a big thank you, my friend
Chainfire is GOD!!!
Thanks . i have rom note4 N910P need suport CR-root
Can Super SU cause the os update to fail? I have a Samsung siii that I got from Craigslist that has Super SU on it and I have tried 4 times to os update with failure. I turned it off in settings but same thing. I reset cell to factory but Super SU is still there. Any suggestions?
thank you so much
I just bought the Pro code from Amazon for my Google Play app version. Seems to work fine so far. Perfect combination! Amazon coins and Play Store updating.
Instead of a flashable zip, can we simply update with an APK file?
Hey can you help with la-912t generic quad core m8382 4.2.2
Thanks A Lot man
How do I update from v2.01 please?
on google play , the latest release is still 2.01 .. any plan to update it there too ?
(using galaxy S4 here)
10% Play rollout is complete, reviewing found issues first before rolling out the other 90%
Can you +Chainfire please Share the apk file..it will be eaiser to install...
thank you +Chainfire I am a very happy user and supporter of your work.
+Ekansh verma you can extract the compressed file, the apk is in the common folder. That's what I use to update.
Good job buddy
+Chainfire - 2.13 had issues on Galaxy S4. No luck even stopping the app, clearing the cache and restarting. Rolling back to 2.0 fixed the issue (App and Log forever spinning). But rolling forward again (auto update in play) brought the problem in again.
+Chris Wells to help find and fix this issue, report to the XDA thread. G+ is not a support environment
Good job !!
You're still great! Thank you so much Grandmaster!
Hi help oppo x9006
Thanks for you work
Men thanks your
Super u dude
How can i autohorize the xmod games for coc mod please answer
So I have SuperSU on my Nexus5 but it is version 2.02. Play Store doesn't show an update and the version of what I see on the Play Store is 2.01. This is really confusing me. Should the Play Store have 2.14 by now?
I root my phone because i want to use xmode but it stuck when i open and restart my phone can anyone help me
A fault in update-binary in 'UPDATE-SuperSU-v2.14.zip' :
if [ "$API" -eq "$API" ]; then
if [ "$API" -ge "17" ]; then
It should be:
if [ "$API" -ge "18" ]; then
I think, Since Android 4.2 needs setuid/setgid flags to be set on su binary.
+Chainfire I can't get SuperSU 2.14 to work in the new developer preview on the Nexus 5. Flashed via TWRP, but on startup of SuperSU it says binary isn't available and it can't be installed. Just a heads up. :-)
Nexus 5 - new lollipop preview, no SU binary installed.
Give the man at least a day guys, jesus.....
Of course. We're just letting other people know that they can stop trying until it gets fixed. Would've saved me 45 minutes to know that sooner.
I rooted my Galaxy S5 back in May using Chainfire AutoRoot for the T-Mobile version, SM-g900t. Haven't flashed anything since; just wanted to have root access for a couple apps.
When Android 5.0 Lolipop rolls out to the Galaxy S5, how can I update my phone to that? Would I have to unroot, update to Lolipop OTA, and root again? (if so, would I have to find a different method of rooting or can I use the same Chainfire AutoRoot?)
Or is there a way to update to Lolipop without losing my root?
Confirmed... Doesn't work with LPX13D
+Jonathan Yee best way is to do clean install. Download your image from samfirmware, backup your data and update via Odin... Then root back again.
+Spiridon C. Dalietos If I have to root again, what method would I have to use? Assuming the firmware version is Android 5.0, would I have to find a root method that specifically works based on 5.0?
+Jonathan Yee the same way you rooted, via cwm or twrp, and yes, you will need root for 5.0
+Spiridon C. Dalietos Would a better method be for me to flash the 5.0 ROM (when it is released) using Mobile Odin? That way I can keep root?
Nexus 5 updated to lpx13d Lollilop just few hours before. I have tried su 2.0 for L, 2.01, 2.02 up to 2.14 with no luck at all... Keep getting binaries errors or installation errors via flash from twrp...
+Spiridon C. Dalietos getting the same thing with new su from op. Using cwm running 5.0. Not complaining just letting you know.
any update coming to SuperSU to support the newest developer preview LPX13D (Nexus 5)? It's currently un-rootable. 2.15?
+Robert Matear I'm sure he's working on it bro. Patience!
+1 for wanting LPX13D support :) Awesome work Chainfire!
Actually there has been a work-around, the latest dev preview is fully rootable with 2.14
Meh! I'll wait till chainfire fixes su.
A few questions +Brad Hoschar
Link for boot.img
Only works with TWRP?
Can i flash that boot.img thru fastboot flash boot boot.img and then flash supersu.zip thru CWM?
Thx in advance
Chainfire I know you'll fix it
Confirming working, Android 5.0 Lollipop Rooted. The Rootable Boot Image: https://www.androidfilehost.com/?fid=95747613655047203 thanks to +sykopompos. Follow Brad's instructions above. Huge thanks +Chainfire for the Root and SU...
I am trying the newest android L preview. But after I flash the UPDATE-SuperSU-v2.14.zip under the recovery[recovery-clockwork-touch-220.127.116.11-flo.img], SuperSU remind me that "there is no SU binary installed, and SuperSU cannot install it.", what should I do?
+Spiridon C. Dalietos have you got a rootable boot image for nexus 7 2013 wifi only?
nope, but if want to experiment you can check this thread out http://www.theandroidsoul.com/root-android-l-developer-preview-nexus-5-nexus-7-2013-patched-supersu/ rootable image http://downloads.codefi.re/savoca/flo/boot.zip... That boot image might work...
+Spiridon C. Dalietos I review the file date of supersu package, it is not for the lastest preview, right? so I have to keep an eye on the thread.
Download rootable image as I have posted above, then download SU 2.14 http://download.chainfire.eu/578/SuperSU/UPDATE-SuperSU-v2.14.zip and flash via custom recovery according to Brad's how to... Get a backup before cause you might brick your 7...
+Spiridon C. Dalietos ok, I got it, I will try it later this night. Thank u！
+Spiridon C. Dalietos oops~ N7 can not boot up with the rootable boot image you post above.
Restore via backup otherwise adb push or sideload original boot image via custom recovery and wait / google for a working rootable Lollipop boot image for Nexus 7
+Spiridon C. Dalietos Thanks for your instructions, I have already flash back the original boot image with fastboot.
Some know how to root nexus 5 android 5.0?????
+Brad Hoschar I tried the boot.img, the SuperSU seems to be no warning out, but it is not working at all. Titaniumbackup and shadowsocks can not work at all. What is the meaning of "not switch your entire system to SELinux permissive mode"? Is that the reason why titaniumbackup and shadowsocks can not be worked correctly?
Chainfire, I'm using on my Samsung Galaxy Note 3 Verizon variant v214, supersu, and safestrap 3.75 with stickmount and it works great no problems at all keep up the good work, I got my first nandroid backup restored to a ROM slot and I haven't got a ROM yet but the phone is stable starting to think about xposed modules and can't figure out what rom I want any suggestions would be accepted used towelroot to root my phone and there was no computer use at anytime any suggestions on Roms , contact me at my gmail which is, firstname.lastname@example.org). On my samsung galaxy note 3, Kit Kat 4.4.2,SM-N900V)(NC4) thanks to Chainfire everything has been working great keep up the good work.
Well that's the kind of backup I need right now and I'm going to do it should have done it already thanks for reminding me if this was directed towards the randelflag, regardless of the conversation you remind me of something I needed to do and that was titanium Thanks
