Unroot old phone - Android Q&A, Help & Troubleshooting

I just recently damaged my new phone and my only option is to use one of my old phones. I just found out that 7 or 8 years ago I had rooted this phone and I am wanting to update the android firmware. I tried to update from the push notification but it does not work. I am thinking either the root or CWM is not letting it auto update.
I no longer need root and have been out of touch with the modding community for a long time. I am sure there is a simple way to do it. I just have no idea where to start. I just want a stock phone. I would appreciate some help thanks.
The phone is a Sprint galaxy S3 Model Number SPH-L710 Android Version 4.1.2

[Q] Galaxy SIII Bricked? Not flashed / rooted.

Hey there. First of all I'm sorry of my bad english.
So I bought Galaxy S3 2 weeks ago. I started phones camera and phone suddenly shut down (got bricked?) Phone is not rooted / flashed. It worked well until now. Phone has 24 months warranty/guarantee, so I dont want to lose it by manually flashing.
What happens? Look this video by me:
if embed not working use this: youtube.com/watch?v=W_PsHpAgSpI
*Volume down + menu + power button combination works, but there is no factory reset option*
Can you help me? What I can do?
If only way to rescue phone is to flash it, can you link me a tutorial and if I do it, can I upload phone via Kies anymore? Will it stay "official".
Fundamental element in order to be able to complete the update process of the Galaxy is to have a firmware entirely original. If you have on your phone a test version, root permissions enabled or a modified kernel installed (e.s , CF-Root) will be unable to update.
Kies in fact, in these cases will not be able to recognize the correct version of the software installed on the Galaxy s3.Finally, in order to be able to update without problems with the tool journal Samsung there is a requirement that many neglect themselves and to which do not lend themselves never attention.
Kies allows you to install updates only if the firmware currently installed on the device coincides with the one provided for your Product Code. For the person who has carried out a procedure of root In this case we can do nothing other than install the firmware manually through the tool Odin.Follow the guide Update firmware with odin ;http://forum.xda-developers.com/showthread.php?t=1671969

[Q] Advice about restoration

Dear All,
I need a little help and wondered if you guys may be able to point me in the right direction please?
I had an S3 which I stupidly smashed to pieces a few weeks ago. While it was off being repaired, I did something bad.. real bad. I bought myself an iPhone 5!
Anyway, I’ve decided to keep it and sell the S3.
Now here’s the thing.. The S3 is running a custom ROM (I think it’s Omega or Wanamlite) and is rooted. But the new buyer wants me to restore it to the original Samsung stuff and have it like it was when bought.. So minus root and rocking the official Samsung firmware.
The thing is that I no longer have Windows XP on my Mac or any way of getting it so I want to know if there is a way of just getting everything back to normal either on the phone itself or just via a Mac OSX app (Mountain Lion)? I’ve never really done this before and used to use the Windows app but the only Windows machine I now really have access to is a work one which won’t let me install anything.
Also, does anyone know how I would do this - as in remove the root – and where I’d get the official Samsung software from?
Thanks in advance for all your help and merry Christmas.
Phil
I think you can try it with mobile odin... But first read please the instuctions

[Q] I need info on backing up android?

Hello, I recently rooted my android phone, but it is not the first time. Due to my last incident with my rooted samsung galaxy S2, I was tweaking certain roms and it ended up getting bricked. I found out about a program called ODIN that can unbrick my phone, but I failed at that and ended up installing a different firmware lol, yet it was still stuck at the start up boot loop animation [IDIOT MOVE] and this time the computer could not detect my phone anymore, trust me I tried hundreds of methods from different computers to different usb ports and different versions of odin and gave up.
However I have a new phone and plan with verizon and ended up rooting the phone again. I did not tweak any roms or uninstalled pre-installed default apps YET. But this time I want to be prepared again if I ever come across my phone being bricked. I am being cautious. How can I have a stable backup of my phone, so if it ever gets bricked I can use odin to unbrick it. Do I have to use titanium backup for this approach or something else.
In case someone asks, it is called Verizon LG Lucid, Model Number VS870 4G, it is 4GLite version 4.1.2. Software verson: VS87011A.
Install a custom recovery such as clock work mod it has the best backup and can bring your phone back from a soft brick :thumbup:
Hit thanks if I helped

Device: Samsung Galaxy S4 SM S975L

Good Morning,
I have a Galaxy S4 Model SM S975L. I first rooted my phone back in 2014 and loved every moment. With that said I have not been able to preform updates because I have rooted my phone. Over the few years I have noticed a dramatic difference in my phones performance (losing signal in the middle of civilization the biggest). I have been attempting to unroot my device the last few months so that I can update it, but my device status remains "custom". I don't have a laptop readily available so I have been attempting to accomplish it via my device to no prevail. Kingo root says my phone is not rooted. I know I need to bring it back to the stock firmware. I have read about Odin and Kies, and I wonder if that will help with my specific device or if I should go another route. Is there a way I can flash stock firmware on my device with out a PC? Any advice will be helpful. Thank You.
PS im not worried about any warranties, Its a straight talk phone. I just want to update it away from my 2014 version of Jellybean 4.3 :/

Sm-g965f root unroot complete restore stock status possible?

Hi guys,
So a couple years ago i was highly active in Android modding. I have plenty of experience with rooting the international variants of samsung s3, nexus 5, nexus 6p, samsung galaxy ACE and an old samsung galaxy Tab.
I also rooted my huawey p10 plus once but reflashed it to stock.
But since then i was more or less inactive on this subject and want to come back now to install adblocker, battery charge manager, xposed v4a and so on. So if i want to install such applications i have to get root.
Now heres my question, will i ever be able to go back to complete stock status on my s9+ (sm-g965f) (exynos)? Like is there a way to reset things like the flash tamper flag on the nexus 5 via script flashing was possible or will the phone once rooted have some kind of mark that cannot be changed if its set once?
Also i need to be able to execute snapchat, netflix and stuff, this k already managed via magisk on an old s6e+.
Im asking this probably rockstupid sounding question because i heard of this fuse samsung built into devices like the s6 i think wich chould not be reset if once blown due to physical changes.. and i dont want to be stuck with a mark that cannot be removed due to rooting the device. (Atleast as long im paying a set payment schedule for the device).
Thank you all for constructive answers.
Greetings
Not possible as of now
