SuperSU says Root undetected - Samsung Galaxy S9+ Questions & Answers

Hi.
Wiped my phone today. Installed FlashKernel 1.0.1 and SuperSU from TWRP. Running stock ROM. Then downloaded SuperSU from Play Store. But SuperSU dont detect root.
Before wiping phone root was working fine.
What have I missed?

Solved: I flashed the wrong SuperSU zip-file

how to obtain root perms and install SuperSU on JB rom?

I installed SuperSu on my X10 with "[cm10] XPERIA X10Z-10.1.A.1.434" Rom and once opened it asked me permission,I clicked ok and it has removed Superuser but after it said me that I had to update SU Binary.The first time I tried to update SU Binary choosing normal mode but the installation failed,the second time I downloaded update-SU_Binary-1.30.zip and I flashed it from recovery but after the reboot,opening SuperSu,it says that executable SU there isn't and SuperSU can't install it.Now,there is a mode to fix this issue to use SuperSu app? If not,how can I reinstall Superuser app? Is possible to root this Rom or I have to reflash it?
P.S: when I connect my X10 to the pc,flashtool says "Root acces allowed",but apps that require root,not work
i solved this issue reflashing the rom without full wipe,now I have Superuser again...
isn't there a mode to install correctly SuperSU on X10 with JB rom?

Latest CWM SuperUser flashable zip

Hi, folks,
I have pretty much wasted the past 3-4 hours trying to get cwm superuser to work.
I installed .314 UK generic firmware using FlashTool & unticked wipe data, then used TowelRoot v12 to root then flashed NUT's dual recovery but no matter what cwm superuser flashable zip I use I cant get it to work right, it always prompts me to use recovery install when I open the SuperUser app, tried that but I just get error saying there was a error installing SuperUser. If I disable SuperUser then install SuperSU & SuperSU pro from market I get root access but SuperSU has always had issues with AdAway applying the hosts file so I switched to CWM SuperUser when I was on .402 firmware.
I did have the flashable CWM zip file but can no longer find it
Really need some help with this.

If you're not on CWM, you can't use CWM SuperUser. Install SuperSU and use that. You can also switch to AdFree which is what I use. You'll also need to install XZDualRecovery to be able to write to /system.

Thanks for the reply
I was using CWM superuser with no issues on .402 UK generic & Philz recovery, I have always had issues with SuperSU both on my old Galaxy S3 with custom roms & now on my Z2, most of the time with SuperSU any app that needs root access will freeze due to the delay in SuperSU showing the alert & as I mentioned above with AdAway not being able to apply the hosts file 90% of the time.
I also have Dual Recovery installed but keep losing it, seems that using the NDR tools app it installs causes the phone to forget that the recoveries are installed.
Just want some help with this issue & it would be great if someone could post a working kitkat CWM superuser flashable zip.
Can anyone else help me with this?
Have just done a full wipe & used Flashtool to install UK generic .314, have used EasyRoot 12.1 to root & it says I'm rooted. I then install CWM SuperUser from market & when opening it says the su binary needs to be updated & only gives recovery install or cancel options, I chose recovery & it reboots into Philz recovery & says it has installed but Philz says root is broken. When I boot the phone again I get a notification from SuperUser saying the binary needs to be updated again but when I tap recovery it just says there was a error.
Really would appreciate some help here as I need to get AdAway installed, change the DPI & use the nextapp kitkat SD fix app.
Cheers.
EDIT: forget it, got it fixed myself, now CWM superuser is working fine.

[Q] Superuser Error -110 cant update or install supersu

My note was previously rooted and flashed using cf autoroot method a long while ago. Last week I tried the ps4 remote play installation and uninstalled superuser for the remote play to actual work. Now I tried to reinstall superuser from the play store and got an unknown error -10. So did some googling and installed it through my recovery (teamwin). Its installed but wont work without an update which also gets an error but an error -110. So I went to my root checker and now its saying my root access is denied. Is there a fix for this? Thanks for any help

I don't think there is a qwik fix. Sounds like you lost something during the reinstall. Do you have a TWRP backup of the OS ? Try a backup restore. If not, BACK UP ALL YOUR DATA TO YOUR PC and do a factory reset. Then try and root again, if it doesn't root then I would odin flash a copy of your stock OS i.e. NC5 or NH7. Here is a link to help with that http://forum.xda-developers.com/note-3-sprint/general/samsung-note-3-rom-flashin-basics-t2896440 Enjoy !!!
Thanks but did some more digging and found a beta of superuser. I installed and it worked fine. Everything says rooted again. Maybe it was just that version

Update supersu binary?

SCH-I545 on stock rooted 5.0.1
I was originally rooted with KingRoot but ran into a few problems and ended up doing a factory reset through stock recovery (obviously since I can't run a custom recovery)the whole wipe data & cache.
After restarting and setting up again, I installed root checker and it said I'm rooted just didn't have any supersu app so I downloaded one from the app store but it keeps failing to update the binary and, again, I can't try doing it through CWM/TWRP.
Is there any means of forcing it to update?
Either kingroot is still installed, or you don't have root (I'm thinking). If you uninstall kingroot, it will unroot. So you probably have a super user app installed (that's how a root checker works- it asks permission from the super user app.) You can switch to SuperSU.... Don't think I can post a link, so just Google: replace Kingroot with SuperSU. After you complete the instructions, then update the binary.

Help lost root! Busybox failed to update and lost root. SuperSU fails to reinstall!

I am running Android 5.01 and I was rooted and Busybox needed to update. It failed and I lost root. I am unable to reinstall SuperSU even though I have TWRP Recovery. When I reboot there is no SuperSU installed and root does not work.
nevermind I just found it easier to start over. restored recovery files back to default stock and rooted phone again. What a mess.
