[Q] How to 'unroot' flashed samsung S5 G900F - Android Q&A, Help & Troubleshooting

Hi all on XDA....
I have recently bought an S5 that, as standard, had loads of bloatware on its standard rom/installation.
To remove it, I rooted the phone using 'CF easy root' through Odin, then put 'TWRP recovery' on and then flashed it with the following ROM -
xXx_NoLimits_6.1.G900FXXS1CQAV (or at least thats what the 'Build Number' states)
Following that I then installed the App from playstore called 'Uninstall' and used this to uninstall all the samsung and vodafone related dross that was draining my battery.
The problem is that I know cannot use Snapchat and more importantly the 'MyEE' app because the phone is rooted. I have tried to 'Unroot' the phone (as I have know deleted all apps that are not needed) so i can use snapchat and MyEE. The problem is, is that I cannot get it to 'Unroot'?
I have tried the 'permanently unroot' option in 'SuperSU' app, I have tried to manually remove the 'root' files using 'ES file explorer' (but it reports that the files I ask it to remove are protected), and I've deleted 'Xpose installer'.... still cant use snapchat or MyEE.
Does anyone know how i can 'unroot' my phone?
Any help is most appreciated.

[Q] GS2 How to completely remove an app...or two

Hi,
Recently I just got ICS 4.0.3 LP8 for my galaxy s2. Basically, I forgot that I had homeMyhome.apk app installed, which basically changes the program that launches when i double tap.
So i deleted this (thinking i was then gonna install the app again);
/data/app/com.vlingo.client.samsung-1.apk
and some other folder associated with it (forgot location)
Then I realized, that this in fact deleted the stuff for homeMyhome, and of course vlingo. Now my double tap does nothing, and I cant install the app again because now it says the program is already installed, even thou it doesn't show up in titanium backup, app manger or anywhere I looked.
tldr; I deleted vlingo voice command and want to reinstall it
My question is I was to restart again, so is there a way to completely delete vlingo and then reinstall it, as well as delete everything associated with homeMyhome, for those who are familiar with it - so i can reinstall it.
if you have ROOT you have to download ROOT Uninstaller
it's can delete any App
Progress!
Alright, i just got voice command to work again by installing a cwm zip. Now I need to somehow remove all remenants of homeMyhome so i can reinstall it properly

Kingroot stuck as system apps

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.
TWRP is an open source project. Their Homepage is https://twrp.me/
The TWRP image files for your device arel located here https://dl.twrp.me/dogo/
SuperSU homepage is https://www.chainfire.eu/ , the latest flashrecovery zipfile can be found here http://www.supersu.com/download
Both projects also have their own sections here on xda.
SuperSU also has it's own sections here on xda.
there's also the problem of the phone not able to connect to google play store (no connection, cannot login account)

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.
Code:

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!

alcatel onetouch pop 4 5051x

Hello, I have an alcatel pop 4 model 5051x.
4 useless apps consume 50% of the battery and I would like to delete them (force stop does not work) and for that I need to root my phone.
The problem is that this model has the bootloader locked.
I tried a lot of methods, from kingoroot to adb but nothing happened. Yet he is recognized by adb.
I also downloaded all the drivers including qualcomm as well as android studio ...
The phone does not even have a day with these apps, help me please!
And if you have the solution, do not hesitate to explain step by step, thanks!
i succeeded !
I succeeded !!!
For those who are interested :
- install Kingroot 5.3.0 apk on your mobile (uninstall the installed app)
- run the root as many times as necessary, making sure that you have granted the administrator and accessibility rights
when the phone restarts, restart it
- as soon as the phone is rooted (be careful it's temporary but you can start again if necessary), install the flashify app
- choose "recovery image", and choose where you put your twrp http.s://drive.google.com/file/d/0B6EQd1aL0EmWX3I2WEFuVmdUcUk/view
- restart on the twrp (I took the opportunity to make a backup above all, count 10/15 minutes)
- launch the Supersu zip install (SuperSU-v2.82-201705271822) that you have taken care to place at the base of your sd card
- restart, supersu is installed
- to transfer my apps, I chose besides the app uninstall system (root)
And finally, here is your Alcatel pop 4 5051x which holds the load again and you can control without parasites
Hi. Now I need your help, since you succeeded, and apparently you're the only one on xda-developers and on the whole Internet!
As I am a complete newbie, please tell me what exactly did you mean in your last bullet ("to transfer my apps, I chose besides the app uninstall system (root)"), and how do you actually remove the 4 useless apps?
Thanks!

"App uninstall system (root)" is an app from Google play but you can choose another one of course, just choose one "root" in order to access to app system.
Be careful of what you desinstall. To choose apps, I've looke on the battery, which apps were consuming the most and I uninstalled they after searching the net to make sure they were not needed.
I offered this phone to my son 1 month ago and he works very well included with 3D games with a long life battery !
Just wanted to confirm that this is working. I installed Flashify, downloaded the TWRP img and supersu zip to my SD card in advance to avoid any issues, and after four tries or so it finally rooted. Thanks OP!

If your device has root access, you can remove King root with other applications or from the King root settings. Uninstall the application with link2sd. If you can not delete the application, you will have to install the stock rom.

Thanks , but after three dots -> i have option to uninstall OR convert to user app.
Under both i get the same error:
"Link2SD could not obtain root access.
Maybe as i formatted my phone, i am no longer rooted and hence the error.
Also, i tried disabling Kingroot from phones builtin "Applications manager" and yes it seems disappeared from my App list on phone, Is it safe to say its no longer working on my phone even in background ?

The application that you deactivated will not run again, but if it really was malware, it probably installed other malware applications. I recommend you to do a complete analysis with several antivirus programs starting with Dr. Web.

How to force install an .apk file

Ok, so i got this free Samsung J2 Pro (SM-250F) from a company where i worked at. It has Knox Mobile Enrollment or something installed in it. I wanted to install .apk file but i can't give the phone permission to install application from unknown sources (the setting is grayed out).
I've tried flashing my phone with stock ROM but it's still didn't worked (the flashing worked but the Knox still there).
So do i have other way to force install the application?
Or the alternative. Is there a store apps inside Play Store that i can install?
Thank you.
