Root Safely Unroot Galaxy S5 *help*

Hello! I have a small issue, and please bear with me as I am fairly new to rooting and the such. I rooted my phone using odin, but now that Pokemon Go got the new update, it doesn't allow rooted phones (this is so stupid, because I had no thought of cheating). I am using android 6.0.1 marshmallow on a Sprint Galaxy S5 and I want to full unroot, safely.

I have SuperSU, and I know there is an unroot option in there, but I don't know if I should use it to unroot, as it says it could stop my phone from booting if something went wrong.

Please help and explain things as if I didn't know much, because I don't understand a lot about this.

Again, this is a Sprint Galaxy S5 on marshmallow 6.0.1, and I would like to know all necessary steps to safely, risk free, unroot. I rooted with ODIN.

Thank you so much, and have a very nice blessed day.

To unroot you will need to download and flash the stock Samsung firmware for your model of phone, CSC and Product codes, as per the instructions and video contained in the links of #1.11 of 42 Galaxy S5 models - Dummies Guide

Thank you very much for your reply! Would you be willing to give me some personal support if I have any questions? If so, would you be willing to facebook message me so that I could ask some questions? If not, I understand. I just want to make sure I don't mess up my phone.

Thank you, please enjoy the rest of your day.

I am not on Facebook. Subject to the time differences, I live in Miss Marple/Father Brown land in the U.K., and my other commitments, it is not always possible for me to enter into real time support. Hence the Dummies Guide. The first thing you need to do is ascertain your phone model and CSC and Product codes as per #1.2 and #1.8 of the Dummies Guide. If you post those details, I can point you to the correct firmware for your phone.

Thank you! Thank you so very much for your help! I have been searching for someone willing to help me.

Model Number: SM-G900P

Also, just so that I am sure I do not type any numbers wrong, here is a screenshot of when I type "*#1234#" to get the CSC.

If you need any other info so that you may point me in the correct direction, just let me know!

And a question: will this reset my phone as if I did a factory reset?
#5 Colby Collins, Sep 15, 2016
I'm guessing you didn't read the bit about installing the Phone Info app if your carrier has disabled the stock stock service code, in the Dummies Guide. The G900P variant has 4 different firmwares and so the Product Code is needed.
#6 ironass, Sep 15, 2016
I will get on that. One moment. Sorry, hehe.
#7 Colby Collins, Sep 15, 2016 tells me that product code is "not active" see screeshot.
#8 Colby Collins, Sep 15, 2016
Any idea as to why it will not give me the product code?
#9 Colby Collins, Sep 15, 2016
Probably root has destroyed it. Below is the latest stock Samsung firmware for your model of phone, CSC and Product code. You can download it and flash it as per the instructions and video of the link I mentioned in post #2, above.

Awesome, thank you. Just a couple questions before I go on with this so that I do not panic while the process is going throgh:

Will this factory reset my phone?

What does the phone do during the process? I would just like to know what I can expect so that I don't get scared that it started to bootloop, etc.

Thank you so much!

It will not Factory Data Reset your phone under normal circumstances. However, as with any flashing procedure, I recommend backing up your device as per post #2 of S5 Update Problems - Dummies Guide.

As for what the phone does, see the video in the link I mentioned previously.

use supersu app it will able to unroot your phone
#13 munemsahariar, Sep 16, 2016
Are you sure it will work? The app tells me this. (Btw, when I rooted with ODIN, it installed supersu on my phone by itself)
#14 Colby Collins, Sep 21, 2016
touch on the option full unroot. if you do not seen this. inform me. it installs superuser on your phone . that means you got superuser access.
#15 munemsahariar, Sep 21, 2016
If you seen the screenshot I posted above (ill post it in this post too) it asks me if I want to do something. Do I press yes or no (this is when I click "full unroot".
#16 Colby Collins, Sep 21, 2016
in my case i have seen this message.

i pressed continue in my case. in your image you have two option one is yes and one is no so, decision is yours but i will be investigate a further why this message shown. i think its need some ota update(over the air), i am not sure. do you have better wireless connection.inform me if you unrooted your phone.

Hope that helps:)
#17 munemsahariar, Sep 22, 2016
Thank you for your reply. Yes, I get the message I screenshoted after I press continue. However, I am worried, as Supersu tells me, that it could stop my phone from booting, and I haven't a clue what to do if that happened.

Please let me know if you have any more input. Thank you so much!
#18 Colby Collins, Sep 22, 2016
@ironass Any input about this supersu method?
#19 Colby Collins, Sep 22, 2016
If you have encrypted your phone, then unrooting, using SuperSU can cause issues which is why I suggested flashing your stock firmware as it will, hopefully, also repair your Product Code thus allowing OTA updates. The choice is yours.
#20 ironass, Sep 23, 2016
i have no ideas about this , just use root checker and inform me your phone still have root access or not. when i used it by presssing continue i closed or uninstalled and root access is flee away. that what i say you to use root checker again. do you send me pic or video that by pressing continue which message is shown.

Hope that helps:)

Thank you so much for your help! I have not yet attempted anything, but here are some screenshots I just took.

The first screenshot shows the message I get when I click "full unroot" in supersu.

The second screenshot shows the message I get when I click "continue" after the message pops up from clicking "full unroot"

And lastly there is a screenshot showing that my phone is, indeed, rooted.

Please guide me as to what to do.

For reference, the only thing I did with root so far is convert an app to a system app using titanium backup, which I will un-do, because I no longer need it.

Thank you :)

You will need to flash the stock Samsung firmware as per my posts #2 & #10, above.
#23 ironass, Sep 27, 2016
But why wouldn't the supersu method work? It says the problem would only occur if I "manually decripted" my device.

I'm not completely sure what that means, but I'm pretty sure I didn't do that.

The reason I would like to do the supersu method is that I do not have the internet resources at my house to download the stock firmware to flash, otherwise I would have tried that already.

So, what I am asking is, is it okay to use supersu to unroot, and if so, should I choose yes or no when this comes up: Screenshot_2016-09-27-15-32-02.png
#24 Colby Collins, Sep 27, 2016
Unrooting using SuperSU does not always work and in this case, its, "attempt", to do so has failed. This is why I never suggested it.
