With all major changes to SuperSU, there are updates to both the GUI and binary. The GUI is the part you see on screen, the binary is what allows other apps to actually acquire root access. The first time you open SuperSU after such an update, it will attempt to update the binary to the latest version.
There are a lot of components to the binary and it needs to be set up just right for everything to work. This is a complex operation, and sometimes it fails. SuperSU is used by dozens of millions of users across hundreds of different devices, running even more different firmware revisions - any change always has the potential to break something somewhere.
SuperSU offers multiple ways of installation: in-app 'normal', in-app TWRP/CWM, and ZIP via TWRP/CWM. These all have their own strengths and weaknesses, so if one doesn't work, try the others if available.
If you are reporting an update failure, you should include at least the following information. Some information requires some skill with adb to retrieve.
- Exact device model
This includes the brand, the model, and the carrier variant (if applicable: mostly USA, Korea, China)
- Exact firmware version
Which exact firmware are you using? If you are using a custom firmware, please include a link to the download for this firmware. If on top of that, you are also using a custom kernel, please include a link to the download for that as well.
- Exact Android version
Android x.y
- Exact SuperSU version
Which version were you running, and to which version are you updating? If using Pro, do you have OTA survival mode enabled?
- Interfering apps
There are some apps that can interfere with SuperSU installation, primarily:
- other Superusery apps
- Xposed
- BusyBox (symlinked or non-symlinked)
Include in your report if you have one or more of these installed.
- Update methods tried
In-app 'normal', in-app via recovery, and ZIP via recovery. If you used one of the recovery options, please include exactly which version of which recovery you are using, and if it's not an official build (so a TWRP not from the TeamWin website, a CWM not from CWM's site, etc) a link to where you got it from.
Note that if you let TWRP or CWM "fix" root for you, or let them disable the firmware from flashing a new recovery (sometimes you are asked this), you have broken root, and the only way to recover it is flashing the full ZIP through recovery.
- What kind of root are you left with?
After a failed binary update, multiple outcomes are possible:
- Root is lost. Apps cannot get root anymore, you cannot get root using "su" from an adb shell, etc
- Root seems to mostly still work. Most apps still work, and/or "su" still works from an adb shell
- Nothing seems to have changed at all, even the GUI still shows the old version number
Report what state your device is in now. Note that you can get the version of the main "su" binary by running "su -v" from a terminal emulator or adb shell.
- Logs from TWRP, when updating the binary using the TWRP/CWM button inside the SuperSU app
After pressing the TWRP/CWM button, the device should reboot into TWRP, do it's thing for a few seconds, then reboot into Android. If SuperSU still complains about the binary, please retrieve the TWRP log file. You can retrieve it via adb pull /cache/recovery/last_log, which should produce the last_log file in your current directory. You still need at least partial root from booted Android to retrieve this log. Sadly it is wiped and replaced with a new file when you boot into recovery a second time, so you cannot retrieve it that way. Note that this log will always contain a number of errors, as the installer tries several things in several ways, that work differently on different firmwares. Attach this log file.
- Logs from TWRP, when updating SuperSU completely via ZIP
If after you boot back into Android, SuperSU is not working right or still asks for updated binaries, reboot back into TWRP, install the ZIP again. After the ZIP is installed, you can retrieve the log file via adb pull /tmp/recovery.log, which should produce the recovery.log file in your current directory. Attach this log file.
- Logs from SuperSU (very important)
If SuperSU keeps asking you to update the binaries after trying any which way and failing, please post the detection log. After updating has failed, don't reboot, but produce detection information via adb logcat -d | find /i "installer" > logcat.txt (Windows, use 'grep -i' instead of 'find /i' on Linux or OSX), which should produce a logcat.txt file in your current directory with several lines mentioning SuperSU. Attach this log file.
- Various logs (very important)
Some additional handy information can be gotten by via some adb shell calls. If you that working, copy/pasting the following commands should produce a nice sulog.txt file in your current directory, which you should attach to your post:
(as always with copy/pasting, make sure you press enter a few times afterwards to make sure the last line was flushed)
Code:
adb shell getprop > sulog.txt
adb shell set >> sulog.txt
adb shell toolbox id >> sulog.txt
adb shell busybox >> sulog.txt
adb shell su -v >> sulog.txt
adb shell su -V >> sulog.txt
adb shell su -h >> sulog.txt
adb shell su --self-test >> sulog.txt
adb shell ls -l /system/xbin/*su* >> sulog.txt
adb shell ls -lZ /system/xbin/*su* >> sulog.txt
adb shell ls -lZ /system/bin/toolbox >> sulog.txt
adb shell ls -l /system/bin >> sulog.txt
adb shell ls -l /system/xbin >> sulog.txt
adb shell ls -laR /su >> sulog.txt
adb shell ps >> sulog.txt
In closing
All this information will help diagnose the problem, and potentially help fix the issue if there is something wrong with SuperSU itself (which is not unheard of). The more information you provide, the better you can be helped. Still, be aware that often it takes a while to get a problem sorted. Even when a lot of people are having the same problem (and many problems may look the same but deep down are separate issues), it is rare to find a user who actively wants to help fix the issue. Most users will only complain but then don't really assist in solving the issue. If you can be someone who can actively help, and by that I mean being responsive to questions, being available for a live debugging session, etc, you are a rare gem indeed, and your assistance will be greatly appreciated.
If you are writing multiple posts, it is always helpful if you keep linking back to your original post with the report. Saves me time.
Sorry for the inconvenience!

Sounds unlikely to be due to SuperSU. Either way, there's nothing you can really do about it now. Situations like these I advise a factory reset and a data restore.

You would restore the data from a backup you've made before resetting ?
In SuperSU you can try 'full unroot' from Settings (twice if necessary) and unroot, see if that resolves the slowness/crashing.
The only backup I have is a titanium backup. I can't get anything to download from the play store. I never flashes recovery because it wasn't available when I rooted. I never went back to add it (which I could kick myself for right now). Would re rooting help? Supersu isn't on my phone anymore either. I'm not sure what happened to that.
Edit: could the platform.xml under /etc/permissions/platform.x ml have anything to do with it?

Samsung N7100 Hong Kong (rom is UK)
N7100XXUFND3
4.4.2
2.14 pro
Don't have OTA survival mode enabled.
Before updating the SU, I can use the SU as usual. But after updating the SU binary via normal, it says I didn't install the execute file ( something like that, since I'm using Chinese), which means i haven't root.
So, do i need to re-root, then update the SU binary?

You can give it a shot, rerooting via the ZIP ( http://download.chainfire.eu/supersu ) with TWRP. See if that helps, and let us know. If it doesn't fix the issue, I will find this firmware and flash it on my own N7100 (if possible) and see if I can replicate the issue.
SuperSU Problem!
I've rooted my device (GT-1335 - Android 4.4) with Windershare Rooting Toolkit, After rooting I've installed Root checker basic from the market and run it. It says your device is rooted. But when i wanted to go to root using FX explorer, it says you need permission from Advance user. When i click SuperSU after that it says that "There is no Su binary installed, and SuperSu cannot install it. This is a problem!", After that i checked whether my device is rooted or not with Root checker basic, but now its says that my device isn't rooted!
Please Help, and replay soon!
Note: My device isn't original samsung model!
super su still loading
After update super su in playstore my s4 octacore in app tab on supersu still loading but nothing happened...
I had problems with using Stock 4.4.4 on my i9305.
Was freezing/not opening, then when it did it wouldn't update.
So I went to the SuperSu site and downloaded the latest to instal via CWM.
Now working fine. Hope this helps someone.

I tried to reroot on my s4, but nothing changes, when updating the SU to 2.14.
So, I think, maybe, the main problem is SU 2.14 on 4.4.2 and 4.3.
My s4 was 4.3 rooted, before the SU update, everything was fine. But after updating, the SU app said I didn't root. Then I updated my FW to 4.4.2(I9505ZHUFNB3), and used CF-root to root. Still ok, but when the SU updated to 2.14, thing happened again. (Now my s4 is temp unroot for playing game , but can't root again as it says "You didn't root")
Sorry for my bad English.

what i have already tryed:
1) On the [Settings]-TAB: => UNINSTALL APP: Effect 'uninstalling...'-popup stays 4ever w/o effect
2) On the [Settings]-TAB: => UNINSTALL APP for a NEW SuperUserApp: Effect 'uninstalling...'-popup stays 4ever w/o effect
3) Booted into TWRP => INSTALL the SuperSU-2.14.ZIP, rebooting phone -> in SuperSU (the same waiting donuts on APPS/LOGS...)

Issue: After update from 2.13 to the latest 2.14 when supersu try to reinstall it stuck more than 5 minutes, I reboot my phone, reopen supersu but now in my "APPS" and "LOGS" I have some kind of neverending loop load, I can't manage to see my rooted apps there, and in my SETTINGS if I try to make some changes it stuck and need phone reboot, otherwise all my rooted apps work fine!

I think i figure out the problem, is the SU bin update. My note 2 is rooted and is using SU 2.14 pro, but i don't update the bin. It works fine, but when opening the su app, it asks you to update the bin.
So recently i rooted my Xperia z1 using kingroot and it went smoothly i got root access,then i tried to switch it to supersu and it didnt work,i have used terminal emulator to run the shell file,the method in which you place mrw folder in phone memory,but it just uninstalls the kingroot and installs the supersu,it didnt upate the root app,so supersu doesn't update its binary,i have tried multiple times and i cant do it manually because i camt mount /system to r/w what can i do? Any help please i am so frustrated with this kingroot app.

First and foremost: Do NOT use Kingroot. There are many threads that explain why Kingroot is shady:
http://androidforums.com/threads/kingroot-safe-to-use.923983/
https://www.reddit.com/r/Android/comments/3vmspw/thoughts_regarding_kingroot/
http://forum.xda-developers.com/showthread.php?t=2604749
Yes, I know there's guides that recommends users to use KingRoot. But unless you want to send private IMEI to China or leak information to the world, just don't use it.
Second, use THIS guide to obtain root.
Alternatively, you can go to the custom ROM route: this will save you a lot of time and headache. Jaguar ROM if you want some AOSP flavor, or DStrikerz if you like Sony's UI. Both includes root, but DStrikerz will allow flashing with locked bootloader. Read THIS for custom recovery.
Hello, new user here.
Since I stuggled with root on my Phone and somehow managed to maintain it, I thought, I 'd share you the stuff I did with you.
I put the TL;DR between hide, if you want to read the story behind my struggle anyway, you are welcome.
I am better with explaining stories then explaining things.
Spoiler
I am using a Samsung S4 mini, Stock ROM and just don't want to flash a cROM.
But I wanted more functions to do - a swiss knife like my old GT-S3650, which was able to boot a PC from.
Most of the things I want to use need root, so why not rooting this sleep S4 mini baby?
And I managed to root it using Kingroot. And all of the things I want to use worked.
After a few days, I noticed network traffic, even with the most network apps and Sync disabled.
Weird? Yes. So I installed "Shark" on my Phone and "Wireshark" on my PC, and started logging.
I noticed an increase of Jabber (the protocol) and a lot of request on domains from China.
Some requests even included my IMEI, how I am connected to the Internet, etc... pretty private Stuff.
I found most of the sources, the IMEI sending App was Shark itself.
Used Lucky Patcher to get rid of it and /etc/hosts blocked the DNS with Hosts Editor.
Did the same with some Kingroot DNS.
But then I asked myself: "Can Kingroot still root my phone, even when cut of the web?".
So I UNROOTED my Phone from Kingroot. Bad idea. Really bad one.
After I ran Kingroot again, it told me, it didn't have a network connection.
I have no idea how I was able to edit the hosts file without SU.
Rerooted the Phone, even if it left a bitter taste of having unwanted network traffic.
This is which made me want to switch to SuperSU.
I tried to mount system as RW prior and installing SuperSU over Kingroot SU. And it failed.
I even tried to make my own uninstall script to uninstall KR by unpacking the Kingroot APK and look what it does.
Not working, the script failed (I am not used to Linux), so I stayed at Kingroot.
While I was working on Kingroot, I was thinking about the idea of having 2 SU Apps, which everyone said it won't work.
But I wanted it to make work - and this is actually the focus on this topic.
During tests, it didn't work as intended, so I stopped working on it and forgot it overtime, resting within my /system.
Days passed, Weeks and Months and I lived with Kingroot, forgot all the trouble and access to/from China.
Recently, I started SuperSU - it was still on my phone. This "cannot install su binary" nagged me and thought:
Oh, why not use this instead.
And then there was SuperSuME... which I didn't want to use, since I was able to brick BlueStacks with it.
But I really wanted to get rid of Kingroot and use SuperSU. This was yesterday.
My phone still has warranty and I think I have Odin here (just in case), but not the 100% exact ROM file.
So I did SuperSuME anyway -I always could return the phone and claim it "broken after OTA update", lol.
Well, SuperSuME did it's Job better then expected and no bricks. Nice Job.
While playing around with SuperSU, I did another mistake.
And here we are... at the main topic.
TD;TR for those who didn't want to read the story:
I rooted my phone 2 times with Kingroot and finally wanted to switch to SuperSU.
After I accidentally broke Kingroot the first time, blocked it's Internet access and unrooted afterwards, I got stuck with a unrooted phone and Kingroot failed to root it.
I was lucky to fix that problem and rooted again with Kingroot.
After months, I used SuperSUME to change that. After SuperSU was installed, i made the mistake of unticking "Enable Superuser". Bad idea.
Tapping "Enable" again, it failed to update the su-binary. oh god. I unrooted again.
While traversing through my directories to start Kingroot again to root, I found my "shadow copy" of SU.
Wut? Shadow copy? Let me explain:
After my first unroot, I wanted to have a SU backup anyway at all costs, just in case I accidentally messup root again.
Now after hours I think I know why it doesn't work.. the normal way, of course.
I installed SuperSU, went into /data/data (or where ever SuperSU has its files) and took a look at them.
Unpacked the SuperSU APK on the PC and gathered all "needed" (I think were needed) files.
I hexedited the most SU binaries from SU to ZU and changed all other referenced binaries as well.
I am sorry about that, Chainfire. I was just testing things.
SU => ZU
SUpolicy => ZUpolicy
setup_su => setup_zu
99SuperSUDaemon => 99SuperZUDaemon
daemonsu => daemonzu
zygote => zugote
I had no idea what sukernel was for, so I left that out.
Why call it ZU? "Sun Tzu" thats why. Known as "Sunzi", he wrote Book about "the Art of War".
After I made sure everything is properly renamed and edited, I moved them onto my phone in the right directories required and chmod them.
I don't know much about that, I just copied the chmod numbers from Kingroot SU and some weird script I found on the web.
Tried to run it using JuiceSSH local terminal, and BAM!! the SuperSU box popped up.
But pressing "Allow" accepted it and nothing else happened.
It became stuck after ZU... it did nothing, but the daemon was running as daemonzu and daemonsu at the same time..
JuiceSSH popped up in SuperSU (while it told me the SU bin was outdated), though.
So I was on the right track, but a piece of the puzzle was missing, so I stopped delving deeper into it.
And forgot about it until about yesterday - where I disabled "Superuser" in SuperSU.
Midwhile the su binary changed from Kingroot SU to SuperSU SU.
Note: It should really ask "Do you want to disable Superuser? SuperSU will delete su binary" Yes/NO.
As I found those files, I started JuiceSSH and typed "zu".
This time, ZU somehow worked like it should.
It spawned a root shell. OMG...
I guess it somehow requires something else needed, which wasn't working while Kingroot was active.
I tried "Root Checker" and it failed. I had no "official" root. But still root available in JuiceSSH.
Somehow I managed to restore SuperSU to normal status. Guess this thing can latch onto an active root user or so.. no idea.
I even screenshotted this, cause I couldn't believe it. If you want, I can post those.
I have now a working second su on my phone, which is hidden from most apps.
But I think it is not perfect, it relies on something SuperSU does or installs during installation.
I apologize again to Chainfire for editing his stuff.
So, now my questions:
1. How can I make it perfect to run standalone, only using SuperSU as a GUI for (Allow/Deny)?
1b. Can we make it part of SuperSU? As a special function: "Install Stealth SU"?
2. Can we use that for something else? -> Probably for this? http://forum.xda-developers.com/apps/supersu/suhide-t3450396
3. Why must the binary be called SU? I know it's for the most apps to do their job and somehow Linux standard.
