How to unroot Samsung Galaxy - General Questions and Answers

Hello everyone,
I have a matter about unrooting a smartphone. I already have rooted my Samsung Galaxy S5 device with Samsung Odin which downloaded from https://odindownload.com/ and it was succeeded. Nowadays, due to some reasons, I need to unroot the device correctly. Though I tried to find enough details about the matter it was not completely achieved. Please help me someone with details or with a link to refer.
Thank you all.

[Q] Samsung Galaxy S Recovery - Please help!

Hi guys,
I am new to the forum and in need of considerable help.
I have a Tmobile Galaxy S 4g (not the SII). I had previously upgrade the phone to gingerbread 2.3.6, but last night I was trying to root it again to do a lag fix.
Unfortunately, I think I used the wrong root file - I used something for Galaxy S GT-19000. Now, whenever I try to start the phone it just switches back and forth from the Tmobile Galaxy S screen to the Galaxy S GT-19000.
I used ODIN to root it, and now I desperately need to return it to factory settings. Can anyone help?
I tried looking for original factory firmware, but I can only find it for the Galaxy SII. Would that even work?
Thanks - I would appreciate any help I can get!

[Q] Galaxy s2 (US) won't load any OS

Hello guys. I want to start off by saying thanks to all of you for the support you've provided. I tried rooting my phone. It's a US Samsung Galaxy s2. I flashed an insecure kernel. Then following these steps: http://forum.xda-developers.com/showthread.php?t=1056334
Unfortunately, it's not compatible with the US phone. So I just want my phone back. Any help would be appreciated.
I've already downloaded the OEM software here: http://forums.acsyndicate.net/showthread.php?4894-Stock-EL29-Tar-How-to-Return-to-stock-here
That didn't work.
I tried also through regular Odin1.85...
Please folks, any help would be appreciated. Sprint said I was effed...
Also, with regular Odin, it gets to about 90% then fails...

Want to enable multi-users on Samsung S4 but can't root phone

Hi!
I want to enable the multi-users functionality on my Samsung Galaxy S4. It runs Android version 5.0.1, so it shouldn't be a problem, but I need to root my phone in order to edit my build.prop file.
Problem is, I own a Samsung Galaxy S4 sgh-m1919v, which is a phone from Videotron in Quebec, Canada.
I've tried Kingroot and Towelroot, but neither will support this phone.
Another common way to root an android phone seems to be by using Odin and going into download mode, but since this exact phone isn't on the list of "approved" devices, I am reluctant to try it... I really don't want to break it.
I've checked on this forum and haven't found an answer to my problem yet.
Any help would be greatly appreciated!
TL;DR: Need help rooting Samsung S4 SGH-M1919V

Screwed up my S7

I have a Straight talk galaxy s7 SM-G930VL that I wanted to root. I followed a video on youtube and did get it rooted, although it's buggy as hell and i cant do almost anything without a "stopped responding" message. I Used Odin to flash an AP file that was given from the video, now when i boot up my S7 it has a little lock that says Custom. To my understanding that means it's detecting a custom rom is in use. Well this custom rom is slowing down my phone, bootlooping at some points, and being a real pain. I can't find the original firmware anywhere online and it's becoming a real headache for me. I need some help figuring out how to get my stock firmware back if possible, or some other solution.
If any other info is needed, I will be glad to provide it, thank you.
Edit: Now I can't even boot up the system. When i do, it says Samsung Galaxy S7 then the little lock icon that says custom, powered by android.
Also I used the recovery settings and it says it can't mount /system
So as of right now, my phone is totally useless.

How to update Samsung Galaxy S4

Hello friends, I have a matter about updating the Samsung Odin S4 device. I need to update my mobile device. Then I tried several methods but it was unable to update it correctly. I got a tip from one of my friend who studies at that university that she told me that Samsung Odin can update the system. Then I found Samsung Odin version 3.09 from https: //odindownload.com/how-to-use-odin.... But I have no idea about how to upgrade my device with Samsung Odin. Can someone help me to know the correct method to update my device to Android Lollipop edition?
Thank you.
