I successfully rooted my Galaxy S3 i9305 on kitkat with kingroot but now after trying to update supersu I have lost root. I have still got the cwm recovery when I boot with the power home and volume up button but haven't managed to get any zip files to re root. Supersu is still installed but won't go past a pop up saying unable to load updates and that I need to do a manual re root. Help with this please as I don't want to have to reset as will possibly lose the unlock on my previous t mobile carrier. Have Ubuntu computer also so can't do any PC fix. Preferably as did it all on phone would like to try sort without computer if possible. Help please please please as losing the will to live!
 
As I understand it you can't have a working custom recovery without having root and Super User installed. Is it actually chainfires SuperSU you have installed and had it working with this fine before updating the app in Play Store or something? What does it actually say when you open the SuperSU app?...needing to update binaries or something?
 
I think it was when I tried to flash supersu binary after installing and running triangle away that things became unrooted. Supersu was asking to update binary from day one of root.
At present I have cwm recovery but no proper root access although some root checkers say I have. It's like I'm in limbo between rooted and not. I have tried to flash the latest supersu from cwm recovery which says successful but doesn't reinstate root access. I haven't got a custom rom just the stock 4.4.4. I only wanted to have root so could remove bloatware and write to SD with file explorer etc. Any ideas?

If you used Kingroot, it installs Kinguser and hard to get rid of on some devices. There is a app called Super-Sume that will replace Kinguser with SuperSu. Not sure which devices it supports.
 
King user not installed and tried running Super-Sume but stuck on preparing environment. I haveutried to reroot with many one click apks and haven't worked.
 
SuperSu says no binary installed= no root. Un install SuperSu and Super-sume then run Kingroot again. look for Kinguser, update its binary,check with root checker app. If all is good,download Super-Sume again. Read instructions how to use depending on Kingroot version you used. Run it and it should replace Kinguser with SuperSu.
 
Rooted a friends S3 SGH i747 in June with pc. Did several factory resets while trying to restore missing IMEI. Didn't loose unlocked status. Maybe as a last resort then start over
 
So you rooted with Kingroot but you didn't have Kinguser installed after root? Or you just deleted it? If the latter the problem is probably that you can't just delete and replace with another super user. If this is the case try installing the kinguser apk and see if you then have full root status. If so we can go through how to swap it to SuperSU properly.
 
Sorry just seen you have tried removing supersu as it is a system app. maybe worth trying the "unroot" setting in supersu and starting again?
 
Ah, also, I would imagine Ubuntu would make it an easier fix than Windows anyway. If the above doesn't work perhaps @EarlyMon will be able to help with his Linux coding wizadry some things to try.
 
I've never been able to remove or replace Kinguser without loosing root. No longer use one click root method unless device has no other options.

Click to expand...

Really? I thought it was pretty easy to change to SuperSU, as long as done properly. What device was that on? I only used a one click method once until a proper root exploit came out, luckily it was only days later so I wouldn't know. But if you have access to computer I would always recommend rooting through that if there is a root method for the device. It's easier and more secure for sure.
 
Been putting myself thru android school of hard knocks using old discarded donated phones. LG Spectrum had me beating my head on desk. Hard to find link to anything useful that still worked. Kingroot team kinda in a tiff with Chainfire,read on XDA, try to post link soon
 
Tried it on the Spectrum, window pops up on SuperSu that another super user is installed and ask if you want it to try to remove it. Didn't work for me Kinguser digs in like a tick. Tried running the script method in terminal,still failed. Finally located all Kinguser files with ES file explorer and deleated them. Only way I could completely remove it. Found different method to root.
 
So if you deleted everything King why not just flash supersu from recovery? or is that what you did?
