Hi!
First of all, I have tried to update my Honor C3 system updates. Then I noticed that I have completely lost root access. They removed su binary. LOL.
Then I tried to root again my Honor C3 with VROOT and it is OK again. But I can't overwrite system files such as changing system DroidSans-fallback.ttf fonts and also installing framework of Xposed (Overwriting app_process). I can't even delete system files also.
I searched for firmware files for my phone and I can't seems to find it. There is root access and I even test it via Terminal Emulator app and from ADB. Calling su binary in Shell was OK but I can't access /system well. Help me.

It's probably either because you need to update the SuperUser binary (go into your SU app and it should prompt you if you do - or switch to SuperSU if you are using SuperUser) and / or you need to use a file explorer (or adb) and mount the system as RW.

I've done it but no work. I'll try another superuser app of course. Thanks anyway.

I should have replied to the SuperSU thread but since I have less than 10 posts...
I was doing a fresh flash/install. The first thing to do of course is to root the phone.
Installed SuperSU 0.94, open it up, says that I need to update the binary, clicked OK, Installation Failed, tried that several times via 3G/Wifi.
Tested under Better Terminal, typed su: not found.
Then I installed Superuser 3.1.3, run SuperSU again and the binary update worked.
Tested under Better Terminal, typed su: # it worked.
Uninstalled Superuser and tested under Better Terminal
SU gone again.
The binary update failure happened before when version<0.7.3.
So why is this? Why do I need to install Superuser to get SuperSU to work?
It depends on what su binary is installed when you root your phone or what app the author of the ROM prefers. You can download the supersu zip package and install it after you install a ROM but even then you'll have to update binary via launching the app itself.

Because every app that uses Superuser permissions needs a a management app to get access to su.

Oh, by Supuruser I'm talking about Superuser - the old app, not the superuser permission.

Yep, you're right, I was just stupid not paying attention to the bat root script. I removed the old Superuser.apk from the scirpt but not the binary.
When I replaced the su with SuperSU binary, no errors anymore. Thanks.
Hi there,
I have a Lenovo A806 phone. I installthe SU binary? Iinstalled towelroot and then supersu. When I try to open supersu, it says the SU binary needs to be updated. I press update, it asks how do I want to install the SU binary? I can select normal or twrp, but both failed.
Any idea, what can be the problem and the solution?
Thank you!
Got 2 option, 1) try to install old version of superuser, 2)reboot to recovery, using File Manager, copy su file from /system/bin/etc/.su to /system/bin/su

So I ran Kingroot, it went to 100% and using a root checker confirms my phone is rooted, and it assigns permissions to apps that request root. Caveat - / and /system remain readonly, Busybox could not install anything and I have no su binary so no question of doing an adb shell and using mount. Is there a fix?

Try that app

Already did, doesn't work. You need an su binary first, like I said even the busy box installation failed.
Try RIC Killer app. Sounds like ric is still enabled stopping writing to the system partition. I'm not sure if it would work on lollipop or with kingroot but that's what I'd do. Search XDA for RIC Killer.

I have the same problem
So please If you find a solution tell me :thumbup:
If I helped, leave a thanks!
I rooted my strange tablet using Kingo and apparently it was succesful:
http://i1312.photobucket.com/albums/t539/talos910/Screenshot_2015-09-11-17-08-20_zpsurdgzj8p.png
But I have been trying for days to erase a file in /system and I have not been able to do it, I think I have read every relevant thread about this problem but no luck, I tried using ES and changed /system to r/w in the root options but when trying to delete the file all I get is operation failed, the same happens with all the other root explorers and tools. I even tried the solution on this thread: http://forum.xda-developers.com/ascend-p7/help/edit-replace-write-files-set-immutable-t2884172
but still can't delete it.
Also the app root toolkit for android gives me this weird error too:

Do you have an app like root explorer that specifically asks for root permissions? It doesn't matter if you have root if the explorer can't use it

Yes all the file manager apps I used always ask for root permission, that is the problem they have root permission but still can't delete the file, which is weird because I can use apps that definitely need root like scr screen recorder and greenify just fine.
Try installing root explorer and then attempt to delete the file, then it should instantly open a window asking for root. The of course grant the permission. That should always work, but if it doesn't just restart the tablet, if it still doesn't work it must mean you are deleting a file that is in use by the system. Otherwise i have no idea whats wrong

Rooted my device using kingo root, I didn't intall other recovery.
Bad idea to try and remove system files without a custom recovery and a nandroid backup made and stored in a safe spot. What are you trying to remove?
I am trying to delete /system/sbin/su because I read in another thread this was the solution to fixing the issue of the app supersu not updating binaries when rooting your device using Kingo.

That is the binary. If you remove it, you wouldn't be rooted. Can you link the thread you are looking at? There's an app made specifically for replacing that su binary with SuperSU and it's binary called Super-SUme, though I believe it is a paid app.
I know it is the binary but according to this guy:
http://forum.xda-developers.com/apps/supersu/support-update-failures-t2907365/page23
(post 223)
""It appears kango wrote to /system/sbin/su whereas supersu wrote /system/xbin/su and subsequently supersu would keep wanting to update 'su' then fail.
The long and the short of it is once I manually removed /system/sbin/su supersu stopped telling me 'su' was outdated. I don't know android but I do know linux.
$PATH on my tablet has /system/sbin/ prior to /system/xbin/ so it would appear supersu is issuing 'su -V' as opposed to '/system/xbin/su -V' when it checks the version. The kingo 'su' was older than the supersu 'su'.
Dunno what the solution is 'cos the older 'su' is going to get called first & I figure there's nothing but trouble to be gained from changing $PATH globally. Nevertheless it might be enough to check $PATH for unwanted 'su' and flag them, possibly offer to remove them? In my case I renamed it "/system/sbin/su.ORIGINAL" so that it's still runnable in an emergency"""
If you rename it, it won't be able to run, and won't require removal.
That's the thing I can't rename the file either for some reason. Using es and other root explorers doesn’t work.

Seems like the SU binary that Kingroot included is pretty finicky and only works for some things. I've rooted 100s of devices and have never had issues like that. Have seen complaints about other various oddities with Kingroot too. It's nice that it's easy and works on a variety of devices, but if you have only limited control then that kind of defeats part of the purpose of rooting it...
Tried using SuperSUme but the app says I am not rooted with Kingo? wtf? Do you guys know of any other reason why i can't erase the system file sbin/su?

With Root Explorer, does it let you set the system to R/W? There's a little button at the top of the app that will say R/O or R/W for Read Only or Read Write. If you don't have R/W to the system, then you are unable to make changes to it.
I just renamed file su and then it became able to be deleted.

Connect your android tablet device to your windows computer. Then enable usb debugging on your android tablet. Then open the windows program called cmd. Then do these commands.
Code:
adb root
Code:
adb remount
Code:
adb shell rm /system/sbin/su
Hello guys,
i've ended in here from another thread which is locked LINK
As the OP of the thread, i've tried several 1-CLICK root apps (both Android and PC) with no luck (Mine is also as gift from mobile carrier).
I have screenshot of "Version" sub-menu, from something called "Factory mode" also i can access the tablet via fastboot and adb (see attached pictures)
Any suggestions?
No one?
I root it using http://www.kingroot.net for PC. Enable. Developers option, then adb USB whatever it was... And should work.

Well... Kingroot worked yesterday. Idk is because i've downloaded latest version or that i've added it as device administrator (also disabled built-in app permission manager).
Now how to replace kingroot with super su? I tried both Super-sume and mrw v2.4 with no luck.
First flash TWRP with the TWRP manager then install root browser goto /system/app delete kinguser restart your phone goto recovery and flash the supersu update

Well...it isn't supported. Is there generic recovery that can be used on various devices based on...idk, chipset?
fyi
I've managed to do it. idk exactly how.
Tried again this mrw (v.2.4) in the root of the sdcard. i'm not running *.sh files from terminal emulator, but via root explorer's script executor.
This time i've mounted /system RW before starting the procedure (found this tip in a lenovo a5000 tutorial that i saved in the past. It can be done via terminal emulator or with app like root essentials).
This time looked like the script hanged, king root has stopped several times and finally "executing script" popup disappeared.
However tried to install SuperSU manual (because script failed)
Then SuperSU returned that kingroot is still present in the system and can try to uninstall it (last time this did unroot the tablet), but with /system mounted RW i decided to give it a try.
Well, now i have fully functional SuperSU and root.
