(Question) rooting and back to stock - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Hi guys
It’s been awhile since I had a Samsung phone
Anyhow I remember that if you are rooting your phone I will not be able to go back to stock and keep receiving updates regularly and also the user will not be able to use any Samsung service since there is some security on the device board
I wonder if it’s still the situation in galaxy s21 series
thanks

Yes OTA updates will be disabled for the rooted device. But you can easily install them if you so wish without loosing root by temporarily removing root without rebooting the device. Follow this guide for full process.
As for the services, I didn't hear about a service that's disabled by rooting. But if it happens you can easily replace said services by downloading alternatives or using specific modules in magisk manager.

Thank you
I’m asking because if I will ever want to sell the device it will be impossible

Not at all.
You can just do this:
Unroot.
Remove Samsung and google account.
Flash stock ROM [Optional, unless you flashed a custom ROM]
Lock the bootloader.
And that's it you can sell it as just lightly used.

I think you wouldn't be able to use Secure Folder after root.

Knox is disabled after rooting, similarly anything knox dependant will be disabled as well. I thought he meant some other services like samsung health or other bloatware.

Down side of rooting ?

Hey there,
I've owned the Note 10+ (Exynos) since release and i haven't rooted it once. I remember the last phone is the note 8 and i did root it, but i remember when i wanted to return to stock to sell that phone i ran into some trouble.
For example the Samsung Pass, Samsung Health Apps etc... don't work anymore after your root your phone, is this still a thing ? Because i'm considering rooting the note 10+ now and i need to know if i can successfully get everything back the way it was before rooting ?
Any help or advice would be appreciated, thanks

hello. yes rooting is a bit of a problem nowadays. Samsung REALLY does not want you to root their Androids for whatever reason. Here are the disadvantages:
1) When you power up the device, a FILTHY boot-up screen pops up and takes 8 seconds and a button press to fully boot the device [see the full details and EXYNOS ONLY bypass here: Boot Pop up remove
2) The KNOX counter [hardware fuse] trips and goes 0x1 [Some devices get OTA updates after locking the bootloader and flashing full ODIN stock, but didn't happen for me. Also it voids the warranty]
3) All the KNOX secured apps [Secure Folder, Samsung Health, Pay etc.] will NOT work [there are bypasses for Samsung Health, Samsung Music and Secure Folder but say goodbye to Samsung Pay]
4) Samsung will refuse to repair your phone and you have to look at 3rd Party options to repair if anything goes wrong. [no bypass to that]
5) Once you unlock the bootloader, you can never lock it again [ idk much about this one, some people say you can lock it again. Gotta look it up ]
Also rooting with TWRP in of itself is a gigantic hassle nowadays [I really miss the days when we could just flash TWRP with ODIN and call it a day].

I mean as far as the boot up issue its fixed so that's fine, in terms of the counter, even if i restored the stock rom and removed root i won't ever get OTA updates ?
Ahhh i seriously hate samsung now ! let me mess up my phone the way i want
Well, that is the price to pay to really ensure a safe device, specially when using banking apps, and corporative enviroments, knox is really good in this regard, the e-fuse is a total warranty for knowing if a device is compromised at deep levels, so, that is how things are these days…
The e-fuse status (0x1) on the bootloader screen can be spoofed to look like it hasn't. Just checking the bootloader before purchasing a 2nd hand device is no longer a guarantee that you have a "secure" device...
This means that if you do get a device that looks secure you might actually get a few nasty surprises when certain apps just won't work or if you try to flash OTA updates yourself through ODIN...
Buyer beware...

yup. even after you full flash stock, it's still gonna be 0x1 and no more OTA updates. But you still can do firmware updates with ODIN (remember it wipes everything including the Internal Storage). Tons of guides on Google, find one.
Just a tiny correction to this thread: it's not true that you can "never" get ota updates ever again. If you flash stock again, you will receive OTAs.
Source: my previously rooted note10+.
As for samsung pay, my country doesn't support it, so no loss there, s-health you get working with a build.prop line, and secure folder is more or less a gimmick for me. As for getting your phone warrantied, i had my friend get his rooted s6e+ replaced for dead camera pixels with no issues. And from what i read european countries have laws separating hardware warranties from software. But i could be wrong on this.
With that being said, unless you have a specialised application for it, rooting isn't worth it anymore imo. It was back when touchwiz was a bloated pos and flashing cyanogenmod gave you a really noticeable advantage, but samsung caught up software wise.
Rooting and installing a custom rom takes me back to good old htc hd2 days.... I've rooted all my phones up to the original pixel. After further looking into rooting and how it can affect security I decided to opt out of rooting for the next 4-5 years. I feel like back then, the OS weren't this customizable as todays phones are. I do miss Xposed Frameworks though
As some posters above say, unless you want very, very badly some app that requires root, it is not worth the hassle and the security issues, I really loved Viper sound, which requires root, but, I decided not to root since the note 7, now samsung one UI gives a very good customization, I do apreciate Knox, and some banking and streaming apps refuse to work on rooted devices, so, I said bye to viper…
Not being rooted, I really miss titanium backup. Every time I get a new phone I end up losing progress or data in some app or other, usually a game. There was one game I had spent a decent bit of money on, years ago now, on my note 4, and it didn't transfer properly to my note 7, and I lost all my progress and the money I had spent on it.
I really feel like consumer protection laws should mandate that the manufacturers can't make rooting impossible like they do. I don't care about losing knox or Samsung apps, heck, part of why I root is to get that crap I don't use off my phone! I miss lineageos. Samsung's android customization isn't to my taste.
I agree with you about root, somebody buys a phone, therefore that person should be able to do anything to it, but, for other part, if rooting is all that important for you, you might very well cosidered getting a rootable device, I rooted my devices in the past, begining with a S3, these days I just miss Viper, but, considering how samsung has progressed with itd UI, I no longer think about root, furthermore, I use a number of apps that do not work when root is detected, so, in the end every one has to think carefully what really needs before getting a device
the only thing i miss on stock, are proper backups as in TWRP or in Titanium Backup, as a lot of things are not restorable with SmartSwitch. also i miss the possibility to completely uninstall bloatware like facebook or netflix and others. i see no reason, why these are part of the OS. CCSWE is quite a big help in that matter, though. for OTA, you can have them, when you re-lock the bootloader and odin stock on the device (at least on the S10+)

as for backup I think I heard about a software called helium, which backs up apps w/o root. Also you can disable/remove bloatware using a PC and ADB w/o root. Here you go: https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/

thanks a lot for correcting me. Even after I flashed full stock on my Tab S3, it would not detect OTA updates and some updates totally soft-bricked it. Editing my post for correction
i went fir CCSWE,regarding disabling.

Tripped Knox with unrooted device

The other day I thought it would be a good idea to root my phone (S20 Ultra Exynos), as it's been many years since I've done it (S6 was my last rooted device).
Anyway, I kept running into issues with connecting to my watch, and getting payment apps working (on account of the root), and decided it was not worth the hassle.
So I unrooted the device via flashing stock firmware in ODIN and locked the bootloader.
I noticed my Samsung Health app didn't work, which was strange. Upon research, I found it was due to Knox being tripped - which was confirmed via downloading a checking app from the play store.
I know that there are patched S Health apps that would allow me to bypass knox, but is there is any way to reset the knox counter so that warranty is no longer void?
Are there also any other implications from this.
So far all my apps work fine, except for health.
Cheers!
It's a micro efuse inside the chipset that blows when you trip Knox.
The only way to fully undo it be to replace the mobo. Yeah... like Fort Knox.

Thought that might be the case.
Bloody Samsung, that's so ridiculous!
Oh well, I haven't seen any other issues with it tripping so far. Warranty is already void anyway since it's water damaged and have had the screen replaced by others.
Thanks!
You're welcome.
Samsung Pay won't work either or maybe Secure Folder. Not the end of the world...

Yeah definitely not the end of the world. I use google pay over samsung, and have never used the secure folder (I use Onedrive Vault).
Are there any other negative effects apart from Samsung Pay, Secure Folder, etc.? I just read that on some older devices the battery life was decreased as well? It's a shame that it can't be undone... I mean, what harm does it do if the phone was rooted (or even attempted to be rooted... it didn't even work!) once. Why should it forever be unsafe from then on? I want to use the phone as stock as possible, original firmware, no root, ...

It's so you know the phone's security has been compromised. Rooting and custom roms makes troubleshooting much more difficult.
Can't blame them for not wanting to troubleshoot other people's firmware on top of their hardware.
Stock Samsung's are relatively easy to troubleshoot...

How can I make my A50 stock?

Hello friends,
I unlocked the bootloader and installed TWRP a few days ago on my A50, rooted it with Magisk, but I don't want to use it like that anymore because I can't use Samsung Pass and for some reason I felt a bit uncomfortable.
Maybe there are more reasons to use it this way, but I'm a regular user and I got into these things out of curiosity.
Yesterday Magisk had been unrooted and the phone was completely out of the way I installed it to test it.
I still don't know if there is a way for me to return to that pure a50 state because Knox I saw something troublesome in a few places, I want your help on this.
What do you think I should do?
I would suspect that you have tripped Knox. This results in that you cannot use many apps, e.g., Samsung Pay, Samsung Health, and Samsung Flow. I think it also includes Samsung Pass.
Unfortunately, this is not reversible as it is in the phone's hardware that it can't be restored once the Knox has been tripped.
You can reinstall the stock ROM if you miss the stock experience, but you won't be able to use these Samsung apps.

yes i can't use any samsung apps. i'll probably root it and try some things changed via buildprop that i saw in some forums, do you think they will work?
Or if I can't make it original, I'm thinking if I should install a custom rom and kernel, I'm very torn. (I'm open to suggestions)

help/info about samsung rooting

hello everyone,
I have and use android phones last 10+ years, always rooted. But I never had samsung phone.
Now I hear only half informations from my buddy, that its dangeous to root samsung because of knox (i dunno what knox even is).
So, now I'm thinking to buy S20 and want to root it, and my question is..:
If I root it, is anything ''broken'' on the phone ? Can phone still recieve official Samsung OTA updates?
What are minuses? what to look for? What about this "knox"?
Please need informaions
Well, I've owned a couple of Samsung devices over the years and I guess I can speak a bit from experience. Here's what you should know:
1.- U.S. phones have their bootloaders locked, so avoid buying a U.S. variant if you want to root it (some people want them for their Snapdragon chips)
2.- Knox is an e-fuse in the phone motherboard. Once you trip it by flashing custom software (root it), then that fuse will be tripped forever. You cannot get your Knox your status back to official unless you change the motherboard. Even flashing stock firmware will never get you this back to official.
3.- A lot of Samsung's security apps check for this fuse and will refuse to work if they detect that you've tripped it. Samsung Pay, Pass, Secure Folder are just some examples of features that will stop working when they detect a tripped Knox fuse. Some of these have bypass with root, but some don't.
4.- You will not get OTA updates with an unlocked bootloader, let alone root. It IS possible to get them back but only after flashing stock firmware and blocking the bootloader. These don't seem to check for Knox.
Understood, Thank You alot for informations and help!

Hiiii. I currently have a Samsung S20 and I have rooted it before. Once you root it Knox security will be tripped and you will not be able to get it back. This means you will lose access to apps like Samsung Pay, Samsung Pass and Samsung Health. You will not receive OTA updates if you're rooted, but if you flash stock firmware again and lock the bootloader you can start receiving updates again. I currently have a custom ROM installed and I have my ROM rooted. To me, it's been a great experience overall. I didn't really use the Knox features, so I didn't care much about losing it. I have loved rooting my S20 and using a custom ROM !!

so, when rooted there are no OTAs.. thats a nono for me heh.. but question, if no OTAs come from mobile itself, is it possible to get uprades through PC then.. (Kies) maybe ?

For your problem, I think the supersu app can allow you to unroot

Unfortunately when you flash magisk, you will never be able to use banking apps even if it's unrooted. That happens because samsung have knox bit which is tripped when custom software is flashed. That happens in phones cpu and it is irreversible.

P.S
You can use banking apps when phone is rooted and you enable denylist in magisk for specific apps. But when knox is tripped and you flash original firmware, you won't have that option
