Losing Root on Sony Xperia Z2 SGP512 Tablet • Android 6.0.1 • Build Number 23.5.A.291 • Security Patch Level: May 1, 2016.
So my issue is not rooting the tablet but retaining root.
I have TWRP Recovery installed and I run RecRoot.zip from TWRP and then boot the tablet normally and I'm rooted. The SuperSU app works and all the other apps requiring root work as expected.
The issue is that within 24 hours after doing the above steps root stops working. All the apps say that I'm not rooted. I checked in file explorer and it shows the su binary is still in /system/xbin. It's just inexplicably the root exploit breaks and I have to keep rebooting into recovery to fix it.
Any ideas on what apps or settings might be causing the device to lose root without any changes being made?
RESOLVED: It turns out the Lookout App was causing root to stop working. I disabled Lookout and haven't lost root since.

I rooted my Micromax A104 KitKat 4.4 with Kingroot and after using for some months I factory reset the phone without removing the root, (without unrooting) now I tried rooting again with the same method as before but I'm unable to gain access to root.When I tried to install the app. It says there is a same application with a conflicting certificate. (Problem is I don't find the kingroot or superuser apps in the apps drawer,and there is nothing to be found even in the list of install apps.) Now, even when I access /system/apps/ folder there is no install apps found in folder.
Note: When I install superuser apps it says su binary needs to be updated and when I tried to update, it fails.
That's because the SU app and binary are not in the normal app places. Basically you will have to either track down where it installs and remove it (will need Root for that) or flash the stock firmware.
Thanks...for the info.
I just updated to 6.0.1 with the January security updates and rooted using su 2.66 which is systemless root so Android Pay should let me set it up on my Nexus 9 but I am still getting the message that Android Pay cannot run because Google cannot detect I am on a valid version of Android. Any suggestions to help? I just want it set up on my 9 for online payments with Android Pay. Systemless root on my 6P using su 2.61 worked on 6.0.1 with the December security patch. I am hoping Android Pay continues to work on my 6P with su 2.66 on January patch.
If you read the supersu beta thread you would know two things: -
1. Systemless wasn't designed to enable Android Pay, added bonus. (Plus google could patch the system in the future to make it stop working!)
2 Delete or rename the xbin_bind folder in SU, reboot and try android pay again.
This question has probably been asked a million times before, but my circumstances are a little different. On my first attempt, I used the "unroot" option on Superuser, and it claimed my device had been cleared of root access after booting back up. However, after realizing my root apps still worked, I downloaded a root checker and confirmed my suspicion that my phone hadn't changed. Afterwards, I followed a Youtube tutorial and deleted various SU files in my system's directory, but partial root access remains. No unroot app works because Superuser can't grant full root access, and SU itself crashes upon booting when I re-download it. I've attempted re-rooting my phone so I had full root access, but that won't work either. Any suggestions?
I rooted my phone using kingroot before and after removing al root authorization i found that kingroot has been installed as system app
also whenever i open the kingroot app it restarts my phone
how could i completely remove it
there's also the problem of the phone not able to connect to google play store (no connection, cannot login account)
my phone is NTT Docomo Sony Xperia SO-O4E
tried factory reset twice, deleting cached apps data, still doesnt work
a basic rundown on how it all happened :
-uninstall some bloatware from phone
-phone starts to restart randomly
-deleted cached apps data, no more random restart
-remove kingroot root auth and uninstall
-found out that phone cannot connect to play store, also kingroot has installed itself as system app

If your bootloader is already unlocked, the easiest way would be to restart the phone in fastboot mode, then boot (you don't need to flash it) TWRP and install SuperSU from a flashrecovery zipfile. This will remove kingroot app and running processes (mind you, there may be some dead kingroot traces left over on the filesystem - if you want to remove these too, you'll have to do so from a shell with root permissions). I haven't tried this with the Sony Xperia ZR/NTT Docomo Sony Xperia A (SO-04E), but it seems to work with most phones that are supported by TWRP. I wrote a short guide on how to do this (it's for a different device but these steps should be mostly generic if you have the necessary prerequisites in place).
Another good thing about SuperSU is that if you don't wish to keep root, it will remove itself cleanly and completely from your system (you'll find the unroot option in the apps settings). If however you would like to keep root, then SuperSU is an app that doesn't spy on you and doesn't phone home (I did a thorough check of the shell script used to install SuperSU and a rough check of the SuperSU apk using strings and wireshark only yesterday and as far as I could tell, it doesn't attempt to do anything malicious or touch files that it doesn't need to touch for its purpose, nor did it start a single internet connection by itself). The automatic NVISO analysis at https://apkscan.nviso.be/report/show/99a7841aa3eeaefa69f767602b0c454c confirms this too. Just saying this in case you decided to move away from root due to spyware concerns.

Was this problem related to the rooting process in any way?
Does your internet access work otherwise?
What happens exactly when you start google play?
hi, thank you for the reply
the phone has only been rooted once with kingroot app, which i have removed (both the supposed app and the root auth), but kingroot app installed itself as system app without my permission and whenever i open the app my phone reboots
i'll try looking for ways to flash the phone
as for the play store, it always show the no connection screen even though i can browse the internet without any problem
i tried following the steps from google help page but it doesnt seem to do anything
i'm thinking that the hosts.txt file cause this so im trying to delete it, but i found no other way to delete it without rerooting my phone
i tried factory reset twice but it doesnt seem to help either
thanks before and sorry for the late reply
EDIT : i dont think i can unlock the bootloader officially so i need an exploit

In that case, you will have to root first. Once having gained root access you can unlock the bootloader. To root, you can either use the kingroot app you used before (not much to loose, since you already installed it and its spyware the first time, and you will later be able to remove it with SuperSU). Or you can try towelroot, although if your smartphone has seen firmware updates, that will propably no longer work. There may be other, more current options - search trough the Xperia ZR Section.
Once you have root, you can use adb and fastboot to boot the latest TWRP for Sony Xperia ZR, then install the latest SuperSU recovery flashable zip. Using that you can completely remove Kingroot even as a system app and afterwards remove SuperSU itself, which will cleanly uninstall itself via Settings.

I would try the above first, see if the playstore works again after you SuperSU has completely removed Kingroot (reboot), and if it doesn't take a look at the hosts file. Then uninstall SuperSU when you don't need root anymore...
I can help along with adb/fastboot commands, but you need to root your device first (and install the necessary drivers for your phone on your computer).
Good luck!
Hello,
I have android TV box model X96H, android 9, allwinner h603, 4gb ram, when I check root access, it's shown as it rooted, but I can't grant root permissions for user apps such link2sd, there's no option in system settings to do that, every time am trying to install supersu, it's successfully installed, but ask for updating su binary, when am doing that update, it's not booting again, I have to install new firmware, I tried kngroot, it's just keep checking on starting of kngroot, is there any solution?
