Question Is it worth rooting? - Samsung Galaxy S21 Ultra

So I will lose warranty in June, and require my phone to be rooted for a few reasons however, I just wanted to know is it likely that the screen could die like others mentioned? and will Samsung repair screen if it's rooted? Also how would I root it? Also could Google Pay work?
I Need root access since I live in a bad reception area and want to use Auto airplane toggle as it would save battery life and other mods.
Anyways, Sorry for bombarding people with questions

If your warranty is done by June, and you root the device after your warranty period, then it doesn't matter if you have a dead screen. You will still have to pay to get it replaced. In case you root before that, you will lose all functions related to Knox.

Thanks. Are dead screens common issue?

How do I root my s21 ultra Exynos?

@amirage: Even if you root after warranty period, you will still lose all knox functionalities

Rooting is also in this post: https://forum.xda-developers.com/t/...t-for-galaxy-s21-series-b-n-0-u-u1-w.4233567/
Btw I am also considering rooting, I just don't know if it is worth it, if there are some good mods that requires the phone to be rooted.

i'd root too if there is a way to revert Knox, if only to optimize them google apps under naptime, in particular, and squeeze out more batt juice, in general. but, sadly, no...

I finally rooted my phone!!!
Just one thing, How will I update my phone for future updates (like one up 4.1)?

You will need to download the latest release for your model from Sam firmware and flash it on your phone.

Every time I try updating my phone I get this error what do I do please help!?

You cant use the system OTA updates anymore. Use ODIN with Home_CSC to update monthly firmware.

Root if something you want needs it, otherwise there's not any need. Do you need tomatoes? I dunno.

As stated above, root if you have the NEED to root. For me, I got plenty. Smoothness, debloating, batterylife, awesome rooted apps out there (I know..only three reasons.) For others, they need a specific app they need to run on their phones and it will need root.
If non of these are an issue to you, do not root. If you cannot think of a reason to root without having the benefit of root vs non root listed out to you, I will advice you do not root because that tells me you actually do not have the need to root. Make sense?
As far as knox is concern...I will say only trip if if you have no need to send it straight to Samsung while your phone is still functioning. I say this because they will send it right back to you. Now if your phone is fried, how will they check exactly if knox is tripped? The carriers do not care, tmobile do not care. Most of the workers think nova is a rooted app. Thats how much they know about root.
You go to a carrier, simply do not give them a reason to think you are rooted. People like to take a phone with custom roms and custom kernels on there...thats not smart. They boot your phone, a message at the top most left of the phone will tell them you are rooted. Always go to the store with stock ^.^
Hope that helps!
I have the Note 4. I root it about 2 weeks later after I got it. My reason: get ride of all the bloat junk that I dont need; now I can write to my SD card; unlimited hotspot; lean machine and good battery life. Its good to have su access.

Im in the same boat, sorta. Ive always rooted. Everything i had, even the old windows phones. This is the longest ive lasted non rooted. Im getting the itch. My question, if i root, flash twrp, does it erase my data? Not a big deal really, but im on level 110 on ea sports king of the course. Would suck to start over.

Neither rooting nor flashing a recovery will wipe your data. Some phones ship with the unlockable bootloaders and the unlocking process wipes the data (for example, on Google Nexus devices). But the bootloaders on T-Mobile Samsung phones are unlocked by default, so flash away

Rooted is the way to go! Only reason I haven't rooted yet is because I'm waiting for Android 5.0 to drop next month hopefully ! Then I will gladly root. Phone is much better when it is under your control.

Those of you who rooted the Note 4, can you confirm if root disables:
Private mode - Possible fix (old fix)
S-Health (maybe only if using Xposed) - Possible fix?
Screen Mirroring (wireless) - Possible fix?
Recording calls (?)
I would want to root mainly to gain access to the external SD card, possibility to enable/disable flight mode using profiles and wouldn't mind about OTA ora Knox 0x01.
But it's annoying to lose those functions for me.
Updated previous post with some links to possible fixes.

I rooted but on a custom ROM and I have zero issues with private mode or S-health. I guess the issue is when you're only rooted on stock ROM. But apparently there's walkarounds for those issues.

Thanks, but actually I was interested on (possible) issues on stock ROM and, most importantly, if the walkarounds really work.

[Q] Pingpong root and Twrp Manager....???

Ok, so i googled a bit and do see that some people have had issues trying this, but most of the examples i was reading were on devices from carriers with locked bootloaders. Since the tmo version has an unloacked BL was wondering if anyone has tried this or not?
I was thinking of simply using flashify or twrp manager to install recovery from within my currently rooted (superuser) rom. Most people that have tried using locked bootloaders endup with a soft brick from what i have seen. Just not sure how much the unlocked bootloader would help us in this situation.
I know i can just use CF auto root but was trying to do it without tripping knox really. However, i have never had issues with any warranty through tmobile (rooted, tripped knox, whatever) and with the announcement of android pay, i am way less interested in samsung pay so tripped knox wouldnt be the end of the world... but still curious
EDIT: So apparently chainfire just released something called flashfire that appears it can do exactly what i am looking for. Anyone else looking for the same should check it out...

So, this will not trip knox? I'm currently stock waiting for the 5.1 update to see if it's worth it to keep stock or root my phone. I just want to root it so bad because I could hypothetically get double battery life with the tweaks I would do. I'm interested in Samsung Pay (sorta) but if Google Wallet/Android Pay will have the same functions, then IDC.

If you install recovery no matter what method it will trip. For Roms, Flashfire won't trip as long as you don't flash boot.img aka kernel. You need to remove it before flashing

Root on AUS Telstra service to use DiskDigger to recover pictures?

Hi all just wanted to find out how to do this
Thanks
edit:
I want to root just so I can recover files as most apps must have root.
Then I will unroot to get samsung pay and reset the knox counter.

Tripping Knox is permanent. You cannot reset Knox, even by unrooting your phone. Only Samsung can do it, and even so, it's very rare.

Thanks so I have done a bit more research and like you said permanent and then therefore Samsung Pay will never work. It will be a while yet before its available in AUS anyway so I'm not bothered.
So rooting is back on the cards to recover my camera album I accidentally deleted. It seems so daunting and over my head though. I don't want to brick my phone.
Do you have a easy and effective recommendation for backing up the note 5 before I head down the path of rooting?
Even then it's not very likely you can get the pictures back. Every time you touch your phone to do anything you are likely to overwrite those old memory locations - even by booting the phone.

Note 8 new user

Hello everybody
Back to android os after many years using note 8 (exynos)
Have many questions want answers
1-My battery sucks so does flashing a custom kernel will preserve the battery??
2-After flashing a custom firmware can i be back to official rom anytime and continue to recieve official updates anytime as i may need secure folder option which is only found on official roms
3-any recommendation for a rom that is stable or a note 9 port for exynos note 8??
Thanks in advance and sorry for the silly questions
Sent from my SM-N950F using Tapatalk
Custom firmware only after root, which will trip knox and thus the end of secure folder (irreversible)...
Congrats! This dwvice is really good, about your batt, why do you say it is bad? How much SOT it is giving you? Average SOT around here is from 5 to 6 hrs, it depends on how many apps you have, and which ones are those, facebook is famous for beeing a batt hog , there are some threads about this, now about flashing some kernel, I think that would help, but regarding the secure folder, once you root, or flash any custom firmware, you will trip knox, and samsung pay and secure folder will be gone FOREVER, there is no going back, no way to revert the knox 0x1 to original 0x0, so, think about it carefully, if secure folder is really important for you, you can only flash official unmodified firmwares, besides, if you trip knox, SHealth will stop working too, although there is a patch to make it work

You will get OTA when you flash an official firmware, some buddies report that it must be a firmware intended for the country where you use the device, and in some cases a specific firmware for the carrier that issued the sim card installed, but some others get OTA with only the firmware beeing official, I think it is carrier related, you will get OTA, just choose the firmware for your specific conutry and carrier to be sure, and if you tripped. Knox, no, no secure folder and samsung pay

I really would not know, I bought my note 8 in october 2017, since then I installed bk disabler pro, to avoid updates,, and I did not have intentions to root, so, I am running stock 7.1.1, for me it was more important to control running services and disabling unwanted apps, I heard rummos back then that samsung was blocking bk disabler with the updates, so I blocked OTA, my device runs very fine this way

Is rooting with Magisk possible?

Hey im new to Samsung phones and got an S10+ preordered. Will I be able to flash TWRP and Magisk the day I get it or will it take some time? Also is there anything special about rooting Samsung phones?
Thank you for your answers!
I would not expect for immediately. Devs need to reverse engineer/hack their way around the firmware locks to attain root and keep the device bootable. Once they do that, the devices are ours. though I cannot imagine it would be too different from the 9 series with flash counters and such not.
Edit: Typos.

If it's the US snapdragon I highly doubt it but with exynos most likely and it will trip knox just like the Note 9.

You will loose Samsung Pay, secure folders and banking apps probably won't work. There is more but that's all that comes to mind right now. Uninstalling root and flashing everything to stock won't fix the lost apps either, it's permanent. I think it will reset your phone too.
Root
Banking apps will work once able to flash Magisk, simply using a system-less root method will allow for work arounds such as Magisk hide etc. which will definitely allow for such apps to work. Exactly as has been seen for the past few generations of devices using Magisk! Anyway... on another note, yes bootloader will very likely be unlockable on Exynos variants allowing for TWRP and custom rom installation but highly unlikely on Snapdragon variants.

Yes because the past root methods trip knox and blow a efuse witch is not reversible. Unless a different root method is discovered this phone will be no different. As the post says above there are some workarounds but that is not a guarantee. Some apps can not be fooled.
