Necessary backups before flashing - Samsung Galaxy S8+ Questions & Answers

Hey,
I might get s8+ really soon and coming from Sony, I've been wondering, is there anything worth backing up before I flash it or right after I flash it?
In Sony devices there's TA partition containing bootloader, IMEI etc which is worth backing up as you can restore TA backup and make your phone look as if it was never flashed. It's there something similar in S8? Or should I just flash it and don't worry about anything?
Thanks for answers.

As a former Sony fanboy, first of all, welcome.
I know that I made the right choice ditching my Z5, though to be honest, it was a bit overdue. My previous disdain of Samsung devices was due first of all to the design and secondly, the bloatware of Touchwiz, but with the S8+ I was stunned into submission.
My question to you, is why do you think you need to flash, before even getting the device, and then what were you thinking of flashing. My experience so far is that there really is no need to Root this phone, there are so many features baked in that are not present on other Android devices. It really is an amazing phone.
I haven't really looked in detail at the threads dealing with flashing, but there are a number that can be found if you do an XDA search. The process of flashing seems rather more complicated than on Sony devices, and depending on what you flash, will trigger Knox, which is a security protocol that a number of secure apps need to run, such as 'Samsung Pay' and 'secure folder'. Tripping Knox also voids your warranty and is a consequence of 'Rooting' and is IRREVERSIBLE.
IMHO, the few custom ROM's that are available don't seem to substantially add value to the overall user experience, but I'm sure there are voices here that will disagree. For instance, there are native baked in features on the device that to all intents and purposes make 'Root' dependent apps such as 'Greenify' and 'Titanium Backup' redundant., and if you want to debloat there are 'non root' apps such as 'Package disabler' and 'Adhell' which is also a good ad blocker.
If you still feel the need to flash there are plenty of guides here on XDA, but good practise, is always to make a full backup.

You should do a "nandroid/TWRP" backup as soon as you install TWRP the first time you load it before you make any "System Modification".
Do a total back up plus an EFS only back up in TWRP. Then reboot Recovery and this time you can modify your system and disable encryption.
This way you have a total stock back up if later on something goes wrong you have a way out!
But please search XDA forum for more details.
Good luck.

First of all, I enjoy modifying phone to my needs, this is how it all started for me. Most importantly I want to develop a kernel for S8+. It made world of a difference on my Z1 and I want to continue my work on S8+, from scratch, but still. I'm currently having a discussion with Samsung support whether they respect EU laws regarding Knox and warranty. As you can see, I've done tons of work so far and I want to continue doing so.
Secure folder doesnt really matter for me, Samsung Pay is soooo limited in Poland, or for that matter, any other sort of payment with NFC/phone, I haven't seen a single shop that was screaming that they support that in Warsaw, but I wasn't necessairly looking around for that, as apart from shop having to have that, bank has to have that and phone aswell, so too much hassle for little gain.
As for other options of blocking ads, they all run actively, not passively, so they put more strain on CPU, package disabler most likely does the same thing as just disabling an app manually in settings -> applications. It doesn't free up any memory in fact.
Not to mention other cool mods that can be done on this device.

Thanks, this is exactly what I needed to know. I'll see what samsung support says about whether they respect EU warranty laws or not and if they do then I'll trip knox instantaneously.

@kxdaorbit I didn't know that samsung implemented a firewall inside of their devices, that's pretty awesome! Adhell might actually do wonders, thanks for info man!

To Root, or not to Root?

Right, I'm getting sick of waiting for the official JellyBean update for my S2, will it be worth it for me to root the fone myself? If so, how do I go about doing it?
Sent from my GT-I9100 using xda app-developers app
Yes it is worth it. Check the international s2 forums and search it up.
Sent from my SGH-T999 using xda app-developers app
Yes it's definately worth it to root. A little risky at first but if you get rooted, your home free and will be loading custom roms almost daily. Many apps will only run on rooted phone. Go for it!
mr
yes it`s worth it.so you can install custom roms.good luck.
It's only "worth it" if you have a reason to.
It's like... "is it worth buying a 30 gallon aquarium for $10" ? Sure, if you actually want a 30 gallon aquarium, it would be - but if you don't, it's just going to sit there unused and taking up space (and in the case of root access, opening up potential vulnerability).
Some people are flash-happy, but I only update mine maybe every few weeks because it's kind of a pain. And I only rooted and flashed a custom ROM on my tablet because it's no longer supported by the manufacturer - meaning a custom ROM was the ONLY way to get updates. I rooted my phone because I wanted to install Google Wallet and that required some work-arounds since my carrier is blocking it.
If you get into unofficial ROMs of updated Android versions, unless it's a leak, there are often problems - various things won't work, bugs, et cetera. It can still be fun, but don't expect it to be perfect.
Find something that you want to do with your device that requires root access and then worry about it.

If you own an Android device, chances are you’ve probably heard of the term “rooting” or “rooted.” If you have and are wondering if it’s for you, this post is perfect, as we break down the major pros and cons of rooting your Android smartphone.
Before we go any further though, what exactly is “rooting”? Rooting refers to gaining access to the "root" user or command prompt of your Android phone. Root access gives users full access to the device and allows for other low-level tasks to be run. Rooting an Android phone is similar to "jail breaking" an iPhone or the "unlocking" of a Windows Phone.
When you root your Android device, you gain access to the entire file system, with full admin rights. You can customize your own boot image, create a full backup of your phone, or install a full-blown Linux distro. Basically, you can do whatever you want.
So, should you root your phone? For me, the answer to that question is a resounding yes, but before you decide, read on to see our list of the major pros and cons of rooting.
Pros of Rooting
Some of the best reasons to root your Android phone include:
1. "Tethering" your 4G/3G internet connection to a laptop computer or tablet via USB cable, Hotspot or Bluetooth. While I don’t recommend this, you will essentially be able to tether for free without paying your carrier a fee.
2. Installing custom themes, mods, and ROMS. This is probably the reason most people root their phone. The ability to deeply customize your own device and upgrade software is very appealing to a lot of rooters.
3. Backing up all the data and apps on the device.
4. The ability to install any application or game, including those "blocked" or Tegra-only games.
5. The ability to underclock the processor to conserve power. This is huge for a lot of people as Android devices are real battery hogs. I have been able to squeeze out days of battery life on a medium-sized battery by underclocking, which is pretty significant.
6. The ability to remove bloatware from your carrier-branded Android device. We all know that carriers love putting quite a bit of crap on their phones and rooting is one way to get rid of it.
Cons of Rooting
Some of the major reasons not to root your Android device include:
1. If the rooting process fails you may permanently "brick" your phone, rendering it unusable for anything other than, well, a brick. Basically, your phone will be useless.
2. Rooting your phone typically voids any manufacturer and carrier warranties. This is pretty crappy, honestly, but some OEMs won't cover certain things. It is really up to the manufacturer. You could lose out big, though, if something major breaks and you have to pay the full repair price.
3. Other drawbacks are more specific to what is done after the device is rooted, such as burning out your smartphone CPU due to overclocking, wearing out the SD card prematurely and burning out pixels in the screen. Additionally, the potential monetary costs that your carrier might apply if they see you've downloaded several gigs of data to your laptop could be big.
4. Rooting usually causes general instability of your Android smartphone. This is a given, as you are basically beta testing modifications and ROMS before they become daily drivers. Expect great performance, but a lot of bugs.
So, is Rooting really for You?
If you're a hacker or tinkerer and don’t mind bugs, I’d say yes. If you’re not, I’d say hold off and make sure it’s really what you want. You must remember that with most phones, once you root, you can’t go back. It is very difficult, in most cases, to completely reset your device to factory conditions, which is definitely something to consider before you decide.
However, if you’re like me--happy with your device as is, but just love pushing the envelope--I'd say wait until your warranty expires. After your warranty runs up, which is usually a year after purchase, there is really nothing to lose.
If you have any additional pros or cons to rooting, leave them in the comment below.
If your warranty is over, definitely root.
Galaxy s2 is a pretty safe and easy device to flash. No need to mess with bootloaders and all. There are many guides in the forum, check them out. If something does go wrong, you will most probably find the solution in this forum itself.
You might might end up waiting indefinitely for the official update for your country from samsung. Flashing it yourself will keep you up to date.
But its time consuming if you are new to all this. There is a LOT to read. I know because I was there. It was after a lot of reading that I felt confident enough to root my phone. But now I flash a little bit to often!
Try a custom ROM based on the latest official samsung. I use NeatROM Lite 4.3, based on LSD. Stable, fast and bloatware free. There are a lot of them, pick the one that suits your need. Or if you're feeling adventurous, try most of them like I did!
Help With Rooting My Verizon Galaxy S3
I Am New To Rooting And I Would Like To Know If It's At All Possible To Install Android 4.2 On My Verizon Galaxy S3, I Feel My Phone Is Very Sluggish And I Would Like To Uninstall All The Bloatware On The Phone. Any Positive Help Would Be Greatly Appreciated Thanks In Advance!
Root
I was feeling the same way on my Atrix HD. Now i am glad i did it, its worth doing, you have greater access to apps, programs, and other things. IT was also simple to me.

Google is your friend, try using it.
Root!!!! I rooted my s2 the first day of having it. Best thing ever. I only update every 2 months or so, make sure bugs are out. I am on ga10 right now which 4.1.2. Even did it to the wife's phone. Original software is not good and slow updates. I am planning on rooting whatever new I get.
definetely root, because with root you can use many hidden capabilities like reverse tethering, free wifi tethering and so on

[Q] Knox, root and "permanent"

Hi All,
I'm reading that root can trip knox, having never owned a Galaxy since the S2 I'm not overly familiar with knox but I've read about what it does.
What is bothering me here is that there seems to be a suggestion that once knox is tripped, that's it. There's no way to untrip it even when flashing a stock factory image again via odin?
Firstly, is this correct?
I'm worried about resale value to the point that I might not care about mobile payments etc, but others might, so a tripped knox could affect value.
If the above is correct I might cancel my pre order, I need root but I don't want a phone that's got limited resale either.

Yes that is correct. Once the Knox flag is tripped you can not reverse it.
I don't think it has been confirmed yet that Knox flag breaks Samsung Pay. From what I have read it breaks software dependant on Knox security, ie the BYOD type apps. They use it as an indicator your device is insecure, so It seems reasonable to assume Pay would break too.
Damn it, What a stupid thing to do.
I can understand it being tripped if you are rooted, but to make it permanent if the situation is reverted is ridiculous.
Thanks for the info, I'll hold out a few more days to see what develops just in case, but I think I'm going to cancel my preorder as I need root but I also have to consider selling it on eventually.
Stupid, stupid decision. :crying:

hey, why do you need rooting your phone?
I thought the same way but now I'm going to use adaway with setting up proxy settings in my wifi and mobile apn connections.
The only thing I should need root for is Titanium Backup, but I think with Helium (by ClockworkMod) backups should be performed easily

Its more than Adaway / Titanium backup, its removing Facebook, Instagram and Skype, which i don't use and or want, being able to run Xposed and root explorer so that i can use MY phone the way I want it without permanently affecting the resale value even if its returned to stock.
Look at it this way, I have a lovely PC for you - top of the line, fast as hell, lots of memory, premium price, but im going to install Windows 8 on there and a bunch of FREE apps , only im going prevent you from removing them, make sure you cant put Linux or Windows 7 or Windows 10 on there until i say so, prevent you from making any change to the Windows directory otherwise we'll stop you from buying things PERMANENTLY and void your warranty on the hardware so that you'll not be able to sell it on. EVEN IF you factory reset it with my software....
Its a shame as i REALLY wanted this phone, but it looks like it may not be for me unless something crops up with regard to KNOX and root.

I'm absolutly with you.
For me it's not a problem because I'm using Facebook, Instagram and Skype. Didn't recognized that they're preinstalled... sry^^
Of course I prefer using the phone the way I want, but it's not as important to me as loosing the warranty. Sure this is quite stupid that Samsung wants to tell us how to use their phone.
If mobile payment will still works with triggered Knox, I'll definetivly root my S6 Edge and maybe try to slim down the stock Rom like I did with my Eragon Rom for the HTC One M7

Yeah - its a shame - hopefully you can still use it, time will tell.
If root comes out without KNOX trigger i'll be all over this - might be too late for day 1 though - i suppose i'll just have to be patient and keep an eye on it.
In the mean time, i'll keep my preorder until the 5th or so then cancel unless something comes up - damn shame though - still i've got my HTC One m8 keeping me happy for now.
There hasn't been solution for KNOX for so long, that it's very hard to imagine that there will ever be one.
I hate KNOX so much, I don't think I will ever purchase another Samsung phone. This is not an absolute statement of course, however it is rather so.

If you have root couldn't xposed just hook that call and return KNOX=True whenever queried? I've seen something similar in the past to make Google wallet work with root and without the secure element it required.

The thing is, Knox isn't just going to be a Samsung thing, after all its a Samsung and Google collaboration and i believe and it will end up spreading. To be honest, i've no objection and it think its a good idea - HOWEVER
I do think the real problem here is that IF the phone is returned to stock it should reset the KNOX flag back to being unset. Simple, everyone is happy.
If i choose to root then fair enough, trip knox as the phone isn't as secure as it should be - i don't expect to have root access or Admin privileges on my work PC normally and if i try to work round it there are logs to indicate that.
However, i DO expect to have it on my OWN computer and without the threat of the hardware being handicapped should i wish to sell it on, that's just wrong.

The problem, from a security perspective, is that there is currently no way to ensure that a phone returned to stock is secure.
Samsung decided from that point to just say once the phone is compromised... that's it. Certain features of Knox disable and, if it's your carrier's policy, the warranty may be void.
But let's be honest from that point as well. Rooting, in most contracts and terms of use, voids the warranty anyhow.
I think many have taken that for granted and don't realize that it can't be in a secure environment.

Why? I don't see how a phone flashed with Odin using a ROM with a verified cryptographic signature cant be deemed secure? Check this - unset KNOX...
This is like saying that once i've installed Ubuntu on a "Windows" laptop it can no longer be deemed secure and while we are at it, lets fry a hardware fuse?
We are SOFTWARE rooting the phone here, not hardware hacking.
I'm actually curious as to the legality of it as well as they are disabling a part of your phone permanently and on purpose because i choose to run a different OS than the one supplied, but i'm no lawyer and there's probably a loophole or a law allowing it somewhere.

What you may be doing is granting software access to root and you may only use root to modify things at a software level.
But you have to keep in mind that's not the only thing root access can do.
It's perfectly legal and I'll even wager they're part of the DoD specification that both they and Apple want to sell to the government.
You have to consider it from a worst case scenario. If a device has been modified in any way, how can they assure it's been reset 100% completely back to stock... both at a hardware, firmware and software level?
Without physically inspecting the phone, they can't - which is why I think this is the way it is.
The Knox team put out a blog entry a while ago about this topic, noting it's a good balance between ensuring security and allowing non-business users to root the device if they want to.
One other note: I don't know enough about the Exynos devices past N2 to say if they've fixed it... but the Note 2's Knox flag was not an e-fuse and could be reset.

Hmm..
Keep in mind here i'm not suggesting apps requiring KNOX are made available whilst rooted like Samsung pay etc, only that the KNOX bit is reset if the phone is flashed back to factory defaults using Samsungs own Odin program and a cryptographically signed firmware. If at that point the phone is rooted again, it would expect it to re-trip KNOX just like it did the first time.
But, lets play a game, lets say i gain root, KNOX bit set and i cant use KNOX apps. I then use that root to make modifications to firmware on the device somehow, which is what i think your insinuating above, not necessarily the Android System partition, maybe the modem firmware (even though its closed source) or something else, for whatever purpose.
IF you have that level of knowledge of the phones hardware then i don't think it would be too much of a stretch to suggest masking the KNOX bit as set would be too hard either, maybe by intercepting the system call to check its status etc but even then when you say:-
"If a device has been modified in any way, how can they assure it's been reset 100% completely back to stock, both at a hardware, firmware and software level"
The firmware and software is taken care of by Odin, that does both, say we did modify the modem firmware above, Odin would write right over it with a VERIFIED image wouldn't it?
Whether you have root or not, you cant do anything about somebody hardware hacking, that's a whole different ball game, if you hacked the hardware you could just change to always respond as the KNOX bit not being set but that would be low level stuff way beyond what pretty much anyone here could do.
Would be interested in that blog post if you have a link - I just don't see this as anything more than a way to discourage more people from rooting.

There are many, many more on the site, just use the search keyword root.
But that's the gist of it - they understand that some may want root for simpler reasons.
Others may want it for more nefarious ways, like trying to access the keys within the TPM.
The end result sucks for consumers; but as a IT admin I can tell you I wouldn't trust a device with sensitive corporate data if it has been rooted... ever.
Thanks very much, I'll take a look when I get a chance later.
Anyone have an idea which carriers enforce the Knox tripping for repair?
Although this looks like a great device, if the Knox trip invalidates warranty, you may be very angry if lets say the usb port or power button malfunctions and repair is not covered.
Might as well buy a Note 4 exynos since apparently warranty is not valid in usa.

Technically the US has a law, the Magnuson-Moss Warranty Act, which should limit manufacturers voiding of warranties to that damage which can reasonably be blamed on the consumer. (for example, rooting your device shouldn't void the warranty for a defective power button) However, manufacturers usually claim the opposite here and I'm not aware of successful legal challenges.
Looks like sprint at least is ok with it

Its more than Adaway / Titanium backup, its removing Facebook, Instagram and Skype, which i don't use and or want, being able to run Xposed and root explorer so that i can use MY phone the way I want it without permanently affecting the resale value even if its returned to stock.
Look at it this way, I have a lovely PC for you - top of the line, fast as hell, lots of memory, premium price, but im going to install Windows 8 on there and a bunch of FREE apps , only im going prevent you from removing them, make sure you cant put Linux or Windows 7 or Windows 10 on there until i say so, prevent you from making any change to the Windows directory otherwise we'll stop you from buying things PERMANENTLY and void your warranty on the hardware so that you'll not be able to sell it on. EVEN IF you factory reset it with my software....
Its a shame as i REALLY wanted this phone, but it looks like it may not be for me unless something crops up with regard to KNOX and root.

I agree. My last Samsung was a note 2 which knox wasn't a factor and not a big push then. I didn't got to any Samsung's after that due to knox.
I just want root for the reason's you do and edit the phone's density.
Its a shame that we cannot just flash back to stock and "close things up" per say if we want to sell it or have a non root related warranty issue.
Knox is mainly geared toward the business side , so why not make Knox activated by a Admin when the phone is to be used for business where the security is needed. And leave it un-activated for the rest of us.
And i would think the ratio of people rooting vs people not rooting (nor even knowing what it is) is so slim that allowing it wouldn't cause a pandemic in warranty claims.
I know before i root anything i make sure all my points are covered and there are processes in place to un-brick a device. Which i haven't had to unbrick a device since my Moto X or OG Droid.

What does one need to do to root a Verizon Note 5? Why hasn't it been rooted yet?

Hello friends,
I'm in the same boat as many of you -- I purchased several Note 5's new from Verizon and then learned that they are not readily rootable....which prevents me from using their full functionality. Irritating.
I have a decent amount of experience with software development/reverse engineering/breaking things/making things work...but I've never messed around with phone firmware before. Usually I connect directly to the hardware chips via JTAG or similar to dump/upload the modified images. I don't really want to crack these sealed phones open though... surely there must be a way to dump/image the phone via the data port? I've read that Note 5 for other carriers are rootable, so how does dumping/uploading bins work for them? What is different about Verizon's model? Are they requiring digitally signed bins? Also I've seen a few people mention Knox....if Knox is tripped does it blow a fuse or can it be reset?
Thx
A
Samsung Knox gets tripped and effectively bricks the device the second it detects root. It blows a fuse. Dead phone.
If you have to ask this question then rooting is not something you need! =D Coming from rooting every phone for the past 5 years, I haven't had a need to root this phone. Granted there are a few things NOT working because of verizon nit picking hsit in the build. Fonts not working for one, nothing that is really a deal breaker. I def dont miss the flashing of builds every week/month, keeping things updated and waiting on developers. Google is smart enough to listen to its consumers and for the most part every new build of android has vast improvements and functionality.. rooting for the most part will be so that you can control the hardware and do whatever you want with your phone, which I believe that is how it should be...i ve stuck with verizon because of the quality of service they provide. Awesome speeds, damn near accessible everywhere, havent had a dropped call in YEARS. But from a tech standpoint, they are a bit ridiculous when it comes to their hardware. I hope they release a line of phones that are rootable and still keep a "protected" option for those who dont want phones that can be tampered with by rooting, security issues, etc.. who knows.. but i wouldnt hold your breath waiting on root for this phone.. best bet is the note 7 coming out and hope a root is found.. but, I imagine its going to just get harder and harder for developers with encryption and new securities..

I understand and agree about the flashing and dealing with the bugs on new roms. All I want is the ability to delete apps I don't want. I know debloaters are out there and they work and that's great and thanks to their developers. I think we are owned the freedom to delete what we don't want. It's like the cable companies sticking us with shows we never want or watch.

I used to feel that way. I used to root every phone I got (if I could) just so I could use Titanium backup to first disable apps and then if I had no problems, uninstall them. Bu with my Note 5 I've concluded it would be a waste of time, even if I could do it. I use Package Disabler Pro (as do many on this forum) and no, it doesn't actually delete apps. They are still there taking up space. but they don't run and unless you are critically short of space, the actual space they consume is minimal. My only complaint against Pakcage Disabler is that I wish it worked on my Asus tablet. but alas, it only woks on Samsung devices.

Has anyone compared Package Disabler to Debloater?
Yeah, Package Disabler is the way to go (IMO). You don't need a computer as with Debloater. Don't get me wrong, Debloater is great, but it's nice being able to disable apps on the go. Not to mention, Package Disabler allows you to export your lists of disabled apps to an XML file, so you can simply import the list back if you need to (say, after a factory reset). Just my thoughts.

So I guess both are good. I wish there am was a place or apply tell you if you needed certain apps or not.

it disables all the bloatware on ure note 5 even without root saves loads of battery and speeds up the device in my opinion
this one works by being a device administrator and it lets u disable tons more stuff than in the standard application manager on the device

I soft bricked my Note 5 and then had problems flashing with ODIN. After I was able to flash though, the screen briefly showed an unlocked padlock. Is that typical? Is the bootloader rendered insecure when you upgrade for a brief window?

Backing up EFS/IMEI partition

Hi there
I can only apologize for having to ask this question, and I do feel a complete n00b for having to ask, but I actually can't afford to get this wrong, so need some help from people who know what they are doing
I've just defected from my Apple iPhone 6+, as Android phones are the only ones that are listed as 100% compatible with my Tobii I12 eyegaze communication device. Using this device I can make calls, texts, Facebook, pretty much anything I want to without needing physical access to the phone.
Now, I also have a Samsung Tab 2 (SM-T700) which I rooted, installed recovery, custom ROM etc some time ago, as it was only a cheap tablet and if it all went wrong, I could afford to wait and mess around to try and fix it.
The thing is, it's more essential my S8+ is working, as I use it with my communication aid to get through to the outside world.
OK, so what do I want to do? Obviously, I'm hoping to achieve root, and one of the reasons for this is because I paid full price for my S8+ (not a network upgrade), the full >£700. This in turn means that I get the privilege of being punished by not being able to use Three WiFi Calling. The signal at my house is a bit shaky, and I read that with a CSC (Country Specific Code) I might be able to get VoWifi working It'd also be nice to know my phone had the capability of running what I want it to....
So, I know that rooting is going to trip knox & warranty void. Not an issue. Having a device that does what I ask it to is more important than some stupid warranty.
However, I have read that before doing ANYTHING, I should make sure I have a backup of this EFS/IMEI partition. Because once it's gone, it's gone for good.
Now I never did anything like this for my tablet, so now I'm just a bit scared I'm going to wipe this partition and completely hose my phone in the future.
So, can somebody please let me know what I should be doing? I really can't afford to be without my phone, but I really need Wifi Calling to work!
Sorry if this is a n00b question that has been answered before. Thanks in advance
Never mind.....
Did a bit more reading today and it makes more sense now.... EFS partition is just a partition on the device; and there are many tools that can backup partitions.... with root, I could even just 'dd' it
Going to take it slowly, but hopefully I can start contributing soon instead of just asking questions
Thanks again
I'm kinda curious about this too, this will be my first attempt at rooting a Samsung and I've seen horror stories about losing the EFS partition in the past.
Incidentally, if you're based in the UK, tripping knox doesn't void your warranty.

Question Knox trigger?

Hey! So, I wanted to know what exactly trips the knox efuse:
-The unlock of the bootloader,
-The installation of a custom recovery, or
-The rooting
Also, what exactly do I lose if I trip it (aside from warranty)?
Just in case: I have a S908E
Thanks in advance
What is a Knox Warranty Bit and how is it triggered?
Features lost when Rooting?
I asked in one of the root threads and didn't get a reply. From looking through the existing threads I understand that you lose samsung pay and the hidden folder feature. I can live with those but is there any other features lost when unlocking...

I believe it's the rooting.
In my case the moment, I flashed something that hadn't the official signature (TWRP), it tripped.

You lose anything that relies on Knox. Samsung Wallet, Samsung Pass, Samsung Health, most banking apps, Secure Folder, and IT management tools like Intune,
So we can agree that unlocking the bootloader doesn't trip knox, right?

Probably not. It's a Snapdragon right? Notoriously hard to root; what's to be gained by unlocking the bootloader?
I leave the firmware alone and use work arounds. It's to the point where I won't even do any upgrades or updates especially OTA. My devices are fulfilling their mission and as such are too valuable to risk losing. Stock loads once optimized can run well, be very stable and long lived with little maintenance.
This N10+ N975U/Pie current load is over 2 yo, still running like a bat out of hell. There was a time it was a stuttering hot running hog... a real pig. I conservatively disabled about 80 apks, mucked extensively with the settings and used a few third party apps for work arounds, to enhanced operation and security. This is what a stock Samsung is capable of.
My other N975U1 runs on 10, it's setup profile is nearly identical in spite of the many dozens of new small Samsung system apks, I left almost all untouched. If it's not resource hog, or a security risk, or crapware like Device Wellness crowding my settings menu I leave it be. I started with the worst offenders and worked my way down.
Android 11 and especially 12 will offer some new very annoying challenges which is why I bypassed them entirely. I loathe the bootloader rollback protection that locks you into 10 and 11 on my device. Moral of the story, look very carefully before you leap. Lol, let Mikey try it first. Where there's little to gain there's a lot to lose.
I still prefer the simplicity, functionality and usability of 9. However I haven't evaluated camera image quality of the 10 variant; it's more of pain to use though is my first impression. Other than possible that and better dark mode there are few tangible improvements and some annoying downsides that will need workarounds.
Scoped storage, some of the rude surprises.
Android 12, dirty pipe... older kernels not effected.
Android 13, if all goes to plan...

I get you. Ever since I've got my S7 I haven't rooted any other phone I had (s10+ SD and this S22U SD as well). This is why I am not updated on the knox thing - Last time I rooted a phone was a S5 exynos). But when I searched for rooting my s22u I stumbled across this knox thing. Researched a bit but still couldn't find the answers to my questions, hence this thread.
Now don't get me wrong, I'm currently not too sold in the idea of rooting my s22u due to the benefits still not outweighing the caveats, but I'm not entirely shut down from the idea. Custom recovery, full access to my folders (I hate scoped storage), enhanced android auto experience... these are some of the things I'd like to have, but then tripping the knox means void warranty, knox-relying apps not working, encryption kissed bye-bye, and half-priced trade-in for the next S23U, if any (I'd like to upgrade it just so I can enjoy full SoC power without the known heating issues of this phone, plus more powerful chip). So, kind of in a dilemma right now.

I hear you. Not even sure you can root it. For my N10+'s because they are Snapdragon's the only way to root them is giving a 3rd party vendors complete access to the device to unlock the bootloader, I believe. If that service is even available for the S22U yet. Do know 100% as this is a passing curiosity for me so I haven't looked that hard. I doubt Samsung have made it any easier in the last 3 years especially for the Snap variants.
You can use adb edits to tone it down a bit. Not sure my favorite package disabler works on 12, someone told me it didn't. Again that's a passing curiosity because I have no plans to upgrade these older phones unless they would run better, which I highly doubt.
