I am using lenovo S820. I updated my phone to kitkat 4.4.2 and lost root access. I tried various apps to root my phone and finally succeeded in rooting with vroot/iroot. As the app is in chinese I replaced the chinese super user with the supersu from playstore with the help of this link. http //forum xda-developers com/showthread php t=2532818. but now I am facing a problem that Firstly I lost root and secondly when I open the supersu apk I get a msg that "there is no su binary installed and supersu cannot install it. If u upgraded to 4.3 u need to manually reroot it. I tried to update the supersu apk from playstore but I get an error cannot update it. Please help how to install the su binary.

Hello, Im new to rooting and I recently rooted my alcatel one touch 918n or I thought I did. I installed a root checker app on google play then it said I was rooted then I looked at the details and it stated that I had some sort of busybox file but no su file or such I tried using titanium back but it said cannot find su binary. Then I tried SuperSU then it said su binary not found and we cannot install it. Any suggestions in installing the.su binary folder or should I try rooting again? Thanks if you reply info info and suggestions help a lot.

Download this to your internal storage http://download.chainfire.eu/372/SuperSU/UPDATE-SuperSU-v1.86.zip - reboot in recovery and install the zip file. Reboot phone, job done.
My device: MMX Unite 2 A106 8Gb
ROM: Stock Kitkat 4.4.2
Root: Yes, rooted with Kingroot
Superuser installed: Kinguser 4.0.0
Problem: My Kinguser seems to want to upgrade Su. Yes, the app says its Su, wheter Su here means Su binary I can't say. (But, either way the problem persists) The problem is somehow the kinguser failed to upgrade that and kept interrupting other apps and giving a push msg "Su upgrade faied. Missing root permission". Though, the root permission does seem really missing coz other apps with root privilege are working fine. But, neither the interruption, nor the push msg ceased coming up.
Solutions tried: I tried upgrading Su binary with Superuser by ChainsDD. But, this Superuser, having outdated binary notification turned on, did not seem to need any upgradation. And, when I tried manually it gave msg "failed" in red. I tried Superuser Update Fixer too. But, it couldn't detect any problem.
Now, I tried SuperSU by Chainfire. And, to my woe, it failed repeatedly to do the initial su binary upgrade in NORMAL way. I tried flashing Update_SuperSU zip from xda developers forum but that instead of doing any good, got the Kinguser hidden and my root privilege broken.
So, now, back to top, how can I upgrade Su for Kinguser when the app itself failed????? Is there any alternative to it??? Help, kindly.....
N.B.: I'm far from being an expert. So, please say all the necessary details of what to do and how to do.

Is there any way to replace the chinese apps with other apps as I dont know chinese

yes, download SuperSU, and copy it to /system/apps with a root browser, fix permission, remove chinese app, reboot
if you install SuperSu from play store it will be something like /data/apps/eu.chainfire.supersu.apk
you can try using it there, but you need to move it to /system before you remove chinese app
there are several root browser/explorer/file manager that will work but it needs to be one with root access options
the chinese app should be in /system/apps not sure of name.
Fixing permissions: Looks like
Read Write Execute
Owner:................X .......... X............ _
Group:.................X .......... _ ......... _
Others:................X .......... _ ......... _
RW-R--R-- 0644
This should correct setting, but compare to other system apks.

You have to reroot.
Try one of these
RootMaster Links
Rootmaster apk or Here
and
Rootmaster.exe run from PC
Most android devices are rootable by one or both these options.

Thanks it worked. phone rooted and chinese super user replaced & supersu installed. having problems in usb reverse tether.
So, It's been a month since I've rooted my phone
I rooted through Kingoapp.com, and it was easy
My OS is Android 4.4.2 KitKat and as the title says,
I want to change from my Kingo Superuser to any other,
Like a normal superuser or SuperSU.. It's because Kingo Superuser
Won't let me use apps like lucky patcher, AdAway etc
I've tried many methods, changing to SuperSU, but its binaries fails
To download, and the other superuser app just sits there, doesn't ask for
Permissions and stuff... That's why I wanna change my superuser app
Any help or effort will be greatly appreciated

[Help] Make Custom Recovery For Karbonn Titanium S201 [Stock Boot & Recovery with me]
Hi Guys....
Can anyone help me???
I have rooted my phone somehow using both IRoot[pc] and Kingroot apk.
But the thing is i don't like kingroot for granting su access so i found one script to replace Kingroot with
SuperSu on top... And i succeeded.
But i found one problem after reboot..
SuperSu Promt was missing when i open up root apps like Root Explorer...and it stuck there for infinite time
and i have to force close it..
But in the Supersu App, i chose an option Default access > Promt to Grant and it worked but without Notification.. and that i what i do not want.. as it will be vulnerable to my device...
So guys , Please help me so that I cant Flash SuperSu zip For Clean Root.. As other methods dont work for rooting, only the above method...
I hope you all Understand...
Regards,
SKERRZ
