Binary update fails on Lenovo Tab3 8 (YT-850F) - SuperSU

I have a Lenovo Yoga Tab3 8 ( aka YT-850F). It was originally rooted with KingRoot. AFAIK there is NO custom recovery available for this tablet.
I was able to install SuperSU, and I CAN "su" from a terminal window, but the SuperSU binary update always fails. Root Checker shows that /system/bin/su is actually a link to the KingRoot su binary (/system/xbin/ku.sud).
Any ideas will be appreciated

Cat s40 SuperSU + Xposed
I have SUCCESS ROOT + SuperSU + Xposed on my Cat s40 :]
1. Kingroot root
2. install "SuperSU_v2.65.apk" ( i installed it by Lucky Patcher as System app)
3. Reboot
4. use script "switch_armv7.sh" i added script i found that on XDA forum but i don't remember where.
If script don't work you can try again gain root by kingroot and in SuperSU update supersu binary ( SuperSU can detect Kingroot so you must uninstall it) This script worked for my Cat s40 fine.
5. After script install new binary in SuperSU app
6. SuperSU succes!
7. FlashFire flash Xposed Binary ( i added too Xposed binary)
7. Reboot ( boot is longer than normal)
8. You have SuperSU root and Xposed Framawork on your Cat s40
You can too by FlashFire make backup your system partition and use it in TWRP if someone do it for us... or flash it after gain SuperSU root ( FlashFire on Kingroot don't working)
You do it at your own risk!
First i tried that method on myPhone Infinity LTE ( i can that flash by computer when it bricked )
I think it can work on all Android 5.1 lollipop.
Wirusx, thanks for the feedback.
Can i get more detail and confirmation :
First use kingroot 4.9.3 found here: http://forum.xda-developers.com/android/apps-games/one-click-root-tool-android-2-x-5-0-t3107461
After that it's rooted, and then you install the script in supersubinary.rar . But can you explain in detail to put what file where on the S40, or do we only need to install the superuser.apk file?
Is xposed framework nessesary found here: http://forum.xda-developers.com/showthread.php?t=3034811
How about use uptodate kingroot and after that supersumepro ?
Rooted Cat S40 running 5.1 Lollipop
After several attempts and reboots all ok. Caterpillar Cat S40 running Lollipop 5.1 working fine.
1st thanks to all devs. (VickyB, MrW0lf, Chainfire etc). :good:
Then. My attempt consisted from pointers or several threads. Started with Wirusx and got something else from somewhere else. I try getting a whole picture here.
(I did not look for fresh look, but better battery consuption, better security and such. So no new roms etc needed. Cat is quite plain and sleek anyway.)
Basically it was of Wirusx instructions, but with some tweaks as apparently at this stage some update has tightened Cat OS that fewer exploits work.
Several files has be in phone (internal storage worked for me, sdcard not). One app from Gplay (Terminal Emulator) and ->
see this thread: http://forum.xda-developers.com/android/apps-games/replace-kingroot-supersu-t3339950
1. Kingoroot - 2. Reboot - 3. Run Script (which will give you also SuperUser app). - 4. Reeboot - 5. Updated Superuser and another reboot.
- Done.
There were some moments when not all ok. After 3, verified through Emulator who is "in charge". "su -v" in same directory as you ran the original script. Showed SuperUser 2.65, so all ok. But apps listed listed KingoRoot/Purify. But not SuperUser, although the root was through it. I had to download it again via Play. After 5 all ok "in Wonderland".
Some pointers from unknown threads (which I failed to find again). Apparently the situation was like the following exerpt shows.
"It seems that the script doesn't work the same way on every device. For me, it just deleted Kingroot,
and left me with just a temporary root terminal, . SuperSU was never launched nor installed,
and when I installed it I got a "There are no su binaries installed".
I did the following to install SuperSU:
1. Run the script for your proper architecture.
2. If it doesn't launch SuperSU at the end or even worse, if you install it but get the
" no su binaries", DON'T close the last root terminal.
3. Run
su -v
If it returns something like SUPERSU-2.65 you're good to go. If it doesn't,
re-run the script again in order to push the proper su binary again.
4. Go to the terminal and type:
mount -o rw,remount /system
chmod 7777 /system/xbin/su
chmod 7777 /system/xbin/daemonsu
Note: at this point SuperSU will start to work, even if you didn't update its binaries.
4. Open SuperSU. It'll ask you to update its binaries, press yes.
5. Since it's highly advised to have SuperSU in /system in order to preserve root access
through updates, you just gotta move the SuperSU.apk included in the zip to /system /app and
chmod it with 0755 permissions.
I downloaded SuperSu from Play and it worked.
Rooted Cat S40 firmware update
Hi!
Is it possible (ad if yes, how) to update the firmware of a rooted Cat S40. My rooting process was the previously mentioned Kingroot -> SU, but after this the OTA update does't finish, even with FlashFire.

How to unroot when SuperSU says su binary needs to be updated

In my 5th gen fire hd7 I tried to root using rootjunky supertool.
I don't know what went wrong during the process but the SuperSU app always says su binary needs to be updated and when I select normal it fails. I'm very much disappointed and annoyed and decided to unroot.I tried the universal unroot app but it fails .nRoot checker says root access is not proper and root explorer can't edit root files.
Is there any way to unroot without updating su binary?

Help: how to update binary file through ADB root shell?

Hi,
I have a ArmA53 based SetTopBox, which has a native root adb shell and build in Google Play. I installed supersu from Google Play and ran it, it told me the binary files need to be updated. I tried to update by using the first normal way, but I failed. And I cannot use the second way by using TWRP/CMW, cause the box does not have those recovery for it.
Is there any other way to update those binary files, or I have to manually update binary files by adb? If I have to, what are the steps to do it?
Thanks a lot.
I delete the old su form /system/xbin, and replace with the new one from armv7 of UPDATE-SuperSU-v2.76-20160630161323.zip.
[email protected]:/system/xbin # ll su
-rwsrwxr-x root root 75348 2008-02-29 03:33 su
This one above is the new su. But supersu said that the device was not rooted after replace with this new one.
[email protected]:/system/xbin # ll su
-rwsrwxr-x root root 75340 2008-08-01 20:00 su
This one above is the old su. After restore to the old one, root is back, but supersu said that the the binariy file was needed to update.

Install SuperSU on MK903V Android 4.4.2 having adb root shell

Hi, I need your help
I have a MK903V Android TV HDMI Stick (Android 4.4.2, API Level 19). I need it to run apps requiring root without prompting for root access - which SuperSU allows.
The stick has a root shell via adb and comes with a su binary ("su --help" says "SuperSU v1.99 - Copyright (C) 2012-2014 - Chainfire"). I cannot boot a recovery like TWRP (I guess).
I've tried:
- install and run superuser.apk v1.99, says it must update su binary, fails updating su binary (normal mode)
- install and run superuser.apk v2.79, says it must update su binary, fails updating su binary (normal mode)
- install and run towelroot, says it got root, install superuser.apk (v2.79), says it must update su binary, fails updating su binary (normal mode)
- rooting via Kingo Root (PC), works including its su prompt on root apps (like the bloatware it installs), running superuser.apk, says it must update su binary, fails updating su binary (normal mode) (never prompted for root)
I found articles saying you could run the installer script from the update.zip, which is used to install SuperSU from recovery, in an adb root shell if you adapt it... I'm not so much into unix stuff / shell, so I'm pretty sure I won't do that on my own. Moving two or three files to the devices and setting chmod/chown is not a problem, but the script looks way more complicated...
Is there actually a version of the script that can run from a adb root shell?
Is there any other way I can get SuperSU on a device I already have root access to?!? Didn't think that could be so complicated...
Thx
P.S. I'd also take a su binary that just grants all access and doesn't even come with a gui
upgrade mk903v to android 5 or higher
How do i upgrade my mk903v stick to a higher version of Android. It comes with 4.4.2 kit kat. Any help would be appreciated...
Thanks
EDIT: SKIP THIS - READ NEXT
Okay, I finally rooted the device...
- Installed KingRoot APK (v5.0.4) from https://kingroot.net/
- Ran KingRoot which did its suspicious magic on the device for more than 15min
- Installed SuperSU and granted it root
- Ran the root.sh script attached which basically kills and removes KingRoot and lets SuperSu replace su binary
- Ran SuperSU again and successfully updated su binary
It is the only solution I found so far...
Sometimes the web just confuses me...
Found this:
http://freaktab.com/forum/tv-player-support/rk3288-devices/17987-new-3288-ez-root-tool
Simple and clean "update.zip" [MD5:7a2755fd5ebe8a2928fc01a4ab0cbabb]
Copy to internal or external sdcard and just reboot or wait for the system popup that says that a new firmware update was found. Update will be applied and device got proper (but old) SuperSU installed.
After that, you may just install the latest SuperSU. (is there a reason why the latest APK is not available on http://www.supersu.com/download#apk ??)

BETA-SuperSU-v2.72-20160510112018 flashed facing issues?

Hi,
I have flashed beta SuperSU 2.72 variant on my phone which is a Le Max 2. Now I had done this when I had installed AOKP marshmallow based custom rom on the device.
Now I have installed Resseruction Remix official nougat based Rom on the device. Now the issue is that the device is showing as rooted via root checker.
Super su installed via Google play store shows Su binary occupied.
Device is not showing any SU tools in settings.
I wanted to know that is how to remove/ unroot the su 2.72?
Is it possible to flash it to a higher version via twrp recovery i.e my installed recovery app? If so I will do so.
I kind of new to Android system so I will appreciate any help.

I have sorted this thing out. I found Su binary occupied means something went wrong during super su installation in twrp.
Just flashed the super su again with latest variant i.e 2.82 and then the SuperSU app began showing up on booting.
Unrooted the Rom from there and rebooted the device. Root removed and everything was back to normal.

Chainfire had stated that when there's an "SU Binary Occupied" message, it means that there's already a Non-SuperSU SU binary file present in the device.
This usually reflects that the SU Binary file was previously installed by another Superuser installation. The SU Binary is more than likely located in the "/su/bin" but, that all depends on where the previous Superuser installation had placed it.
For LineageOS users, this is typical of the users having the LineageOS SU installed from the LineageOS Extras.
Seeing that you've got it all under control then I wish you the best of luck!
