Last time I tried rooting was in 2016/2017 using Super SU but now many years later I want to try to root my phone again. I have Galaxy S21 ( Exynos ) and I was wondering what would be the easiest way that won't cause too much trouble.
What are the pros and cons of rooting a phone in 2021 and are there any dealbreakers like not being able to recieve system updates or banking apps not working at all.
I would also like to know if there are any android 10 based custom ROM's for Galaxy S21 currently?

In order to root you need to unlock your bootloader, which means no system updates. Most apps will still work if you install Magisk (SuperSU equivalent). There are not really any roms yet, but you can see that easily from the rom section of this forum:

Hi,
Since there's no custom ROM for this model, I wanted to try the GSI way.
I've installed TWRP on my S21 (o1s) following this procedure : https://forum.xda-developers.com/t/...-for-galaxy-s21-exynos.4241869/#post-84592059
Then, I flashed /e/ OS from here : https://images.ecloud.global/dev/treble_arm64_bvN/
However, the phone keeps bootlooping after displaying "This phone is not running Samsung's official software. You may have problems with features or security, and you won't be able to install software updates."
I believe I'm missing a step in my installation (something about vbmeta maybe ?). Can anyone help me ? It's my first time dealing with recent Samsung phones (= post-Galaxy S9).
(I've also posted this question here : https://github.com/phhusson/treble_experimentations/issues/2006)

Hi all and thanks for the precious and detailed information you posted in the Forum.
I am quite new with Samsung (Android).
Just left the other World few months ago.
I was using the iPhone and switched to Android because of different considerations like battery, higher display, etc.
I am interested in ROOTing my device (Samsung S3 - GTI9300 International).
May I ask you a couple of questions about this step?
- The ROOT process will remove my installed applications
- After ROOTing the GooglePlay will still be available to update my Applications
- Future FIRMWARES update from Samsung will be available also for ROOTed devices
- unROOTing the device means (easily) reinstall the original FIRMARE or there is an easier step
Many thanks for your (all) help!!!
Happy Android
It depends of how you root it (if you install acustom rom or not) but if it's only the root itself it will not change your phone at all, still your apps, google play working.
But you'll not be able to change firmware with kies, only with flashing new roms. Also unrooting is not hard, and everything is really weel explain on the s3 forum here in XDA

I am just starting.
Interested in ROOT process only by now and of course the unROOT step after.
I will check the S3 forum as per your kind suggestion.
Trying in a while to load and use a "Custom Rom".
Thanks a lot for your replay!!!!!

Hi Everyone,
I am seeking some advice regarding our beloved Samsung Galaxy 2. I owed this phone in the past and after testing other devices, I am considering to purchase it again. Please kindly try to answer my questions:
1. I have Spinal Muscular Atrophy and I think the S2 is one of the lightest and thinnest smartphone on the market. Do you have any other devices in mind that could be suitable to my mobility issues?
2. I have purchased a few smartphones online (ebay and amazon) and always had difficulties to find one that is “truly” unlocked. Most of them were entitled as “unlocked” but would not work with my sim card. Do you have any advice on this issue?
2b. Do all S2s have the same processors/ram/features? Do you advise any S2 version in particular or all of them are fine?
3. I am interested in those new voice recognition features such as Ok Google/voice and my guess is that the most efficient and reliable versions of it are present on the latest Android versions such as Lollipop/is there any correlation between Android version and Voice recognition efficiency?
3c. Do you think it would be possible to install Lollipop on a S2 and how?
3d. Would it be a simple and “official” update or will it necessary imply a “jailbreak”? Knowing that I am definitely not familiar with this kind of process, are there accessible and straightforward tutorials for newbies showing how to proceed step-by-step?
3e. Would it slower the S2 to update it with Lollipop or create any other issue//conflict/flaw? If so, until what Android version can I update without slowing the S2?
Many thanks for your kind help!

1. Sorry no idea here.
2. By rooting your phone you could remove the branding and use any sim card
2b. The most common version of galaxy s2 is the international one gt-I9100. Depending on the year of when it was made there could be a slight difference in processor. Older processor need more voltage than the newer ones and might not be able to overclock as much as the newer ones. But if you don't intend to undervolt your phone this is unimportant for you. All of them work with 1.2ghz. Which processor type you'll get is some kind of luck I guess.
Gt-I9100 aside therealso are gt-I9100P and 9100g. I'm not sure but I think they work with same specs as the international one (1, 2 ghz and 1gb ram) but they use other hardware and thus it's not as easy to find custom roms like for the gt I9100 I think.
Furthermore there also is the galaxy s2 at&t version. If I'm right this the t mobile version of this phone. It also has the same specs like the other models (different hardware too) but the difference is this phone has no physical home button, which for me, looks better somehow.
I'd suggest to take the international one gt I9100 or the at&t version.
3. Official android version of the galaxy s2 models is jelly bean 4.1.2 which also is required by Google search and Google now. I assume it doesn't matter rather you have android 4.1.2 or 5 regarding the voice recognition.
3c. At the moment it's not possible to install Lollipop on a S2 but it may be possible in the future. You'll have to root your phone therefore and flash/install a custom rom based on lollipop.
3d. Like already mentioned earlier you'll need to root your phone in order to get past android 4.1.2. Depending on your phone model (2b.) It can be extremely easy or a bit more difficult. I'm just used to the international version gt I9100 which can be rooted with an app via one tap. That aside there are various step by step tutorials, as the galaxy s2 is a very popular phone.
If you'll root your galaxy s2 I highly recommend to Google emmc brick bug before doing so.
3e. All official android versions can become slow after some time, especially because of not removable, pre installed apps. With root you have the possibility to remove those and make your phone faster. If you intend to stay on official firmware you should update to the latest (4.1.2).
Talking about getting slower with higher android version is a bit difficult here. Theoretically with higher android version the phone will get faster....at least that's what Google says.
However as already said the galaxy s2 is stuck on 4.1.2. The only way to get higher are custom roms and those can be slow or fast no matter on which android version they are based.
For example cyanogenmod 10.1.3 is the fastest firmware I've had till now and it's based on Android 4.2.2. Jelly bean. Next there's for example aicp rom based on 4.4.4 KitKat. This version wasn't very fast for me. Another KitKat rom, NeatROM, however was faster than aicp although it has same android version.
It always depends on your personal phone, because each phone (or each galaxy s2 in your case) reacts a bit different to it's firmware and also on the way the developer made their custom roms.
You'll have to find out there

Hello, I am super new to xda and to phone rooting. I've recently got a Xiamoni Redmi Note 4 and I really want to root it to unlock the FULL potential of my phone. I'll keep the rest of this thread short by asking:
1. Does MIUI Version matter? I am currently on Global 8.5 l Stable 8.5.4.0 (MCFMIED) Android Version 7.0 NRD90M I am also on a snapdragon
2. Once I unlock my bootloader, is the bootloader unlocked for good?
3. Where can I find a systemless root guide for my phone? (FOR SNAPDRAGON)
4. What are custom roms exactly? What would you suggest?
1) IDK if MIUI version seriously matters but I'd highly recommend to update it to the latest stable.
2) Bootloader is locked for the security of phones, for common users. For further read, see this.
3) Search for "Magisk". You'll VERY easily find the guide and everything you need.
4) Custom ROM is technically an OS. Very usually they're just different flavors of Android. When you flash a custom rom in your phone you're basically changing the phone's OS. You usually get the benefit of getting a smoother, clutter-free phone with a custom rom, well obviously there're risks which you know (or can google).

Nope. I can't tell anything beside these facts. Nice reply. Only that I'd suggest avoiding miui roms and once rooted, flashing of a pure, aosp based Rom.
Sorry in advance if this is common knowledge. Semi-noob. I searched forums far and wide for past 3 days for this info.
Device: Samsung Galaxy S7 Edge SM-G935T (Snapdragon)
I have the latest Samsung/T-Mobile firmware installed (July 2019 update) with Binary 10.
In a nutshell:
From what I have gathered, Samsung Galaxy S7 Edge (T-Mobile) has a locked boot loader, which means that it CANNOT be rooted or modded (at this time). Is this entirely correct?
In detail:
I switched my phone service from T-Mobile to Safelink with the same phone and ported phone number. The warranty is expired, and I accept the risks. I want to get rid of T-Mobile bloatware on my unrooted device, and even install custom ROMs so that I can experiment with the possibility of better WiFi signal strength and other fun stuff. My phone is great, but it does not run as smoothly or fast as I would like it to.
Tutorial after tutorial has resulted in dead ends (SW Check Fail using Odin and download mode, Heimdall, etc.). The main issue seems to be that the binaries cannot be older than what I currently have installed, and I have the latest one, Binary 10.
It is my understanding that this cannot be navigated, unless I get off my butt and figure out how to exploit it myself. Is this correct?
If not, is there any way to get around this locked boot loader issue with the SM-G935T having the latest stock firmware (Binary 10)?
You guys rock.
Tap
I swear to god I've been strugling for solid 1 hour just to find a proper firmware binary 10 just like you. But it seems like worthless. If you find anything please help me *sob*
did you find the solution yet? cz am in the same situation right now, my phone is running on the latest binary 10 like you said...
Hi, i have issue to flash twrp on my galaxy S9+ (to flash a custom rom after) I have read tons of old thread that did not work for my phone (flashing official rom and wait for 168 hours or more, connect to the internet and so on...) none have work so far, even with OEM unlock on!!!
I try to downgrade to android 9 but get a message as it is not allowed from odin.
Is there a way to flash a custom binary to this phone? I have a recent updated android 10 as official rom and get the message RMM state prenormal when trying to flash twrp ("Only official released binaries are allowed to be flashed")
Here the screen capture of information about the version that is installed on my phone (an official rom from sammobile for my country XEF)
I am getting crazzy with all wrong information and wrong tuto that never work for me.
Plz help me or tell me i will never be able to install TWRP on my phone, i need reliable information about what happen really on my phone.
I can't believe that samsung win this war and force us to stay with all this google ads and preventing us from being able to root this smartphone.
Sorry if my english is not perfect, i used this site to find custom rom for so many years now, i can't believe my phone will stay locked for ever.
Thank you for your kindness.
a desperate galaxy S9+ user.
hi , I am also meeting this problem with no working solution. If you have any solution @ me please~
