Is this service still available? (SM-G998U1)
[Samsung Galaxy S21 Ultra] en11gma:
i have USA T-Mobile SM-G998U on W12 official tmobile firmware.

can device still be unlocked?
[Samsung Galaxy S21 Ultra] d3vils2:
Can you get OEM unlocking and how do you do it?
[Samsung Galaxy S21 Ultra] spadesone:
Hey man. We have the same problem. You already found the solution?
[Samsung Galaxy S21 Ultra] tutruelove1:
Hi i want to try this, I rooted other phones before but I got a s21 ultra U1 yesterday, in developer options it seems there is no OEM unlocking option, so what I can do ?
[Samsung Galaxy S21 Ultra] d33dvb:
There is NO bootloader unlock. Make one , make monies.
[Samsung Galaxy S21 Ultra] dan.dior:
Hello... even it appears now at the S22(maybe as well with the S21),

Magisk would probably have to be adapted again?

I have an normal Samsung S22 with the newest EUX Firmware.

The “CIDManager” (service provider update) complains that no updates can be carried out due to the modified (rooted) Android system.

The pop-up message for updating appears constantly repeated with the restart request, which then does not happen. Of course, restarting does nothing.

Multidisabler (3.5) and something like that can't do anything either?

Any suggestions? THX!
[Samsung Galaxy S21 Ultra] xAD3r1ty:
Guess this also works on the HK variant? (G9980)
[Samsung Galaxy S21 Ultra] akira022:
I have one by T-Mobile in the US with no OEM Unlock either. I just don't understand why the us versions of phones just try to make it so difficult to root phones. Not like its illegal. I understand that it will void our warranty because if something goes wrong its our fault(99% never happens though) In the last five years I have noticed this. My last phone, the LG v30(T-Mobile version) was a pain to root. I think just unlocking the bootloader and installing Magisk should be the only thing that should be required. What do they do...not sell you the phone they just "Lease it"?
[Samsung Galaxy S21 Ultra] afaneh92:
Why to patch 6GB file while you can patch 67.1MB file!
[Samsung Galaxy S21 Ultra] Max128:
Is the same thing in Canada like in USA , samsung have locked the bootloader so you can not unlock it for the root and more.... Since the samsung S8 i think and yes is stupid. What I suggest and what I do before is buy the global version with the snapdragon, is more cheaper, have dual sim and the bootloader in unlockable easy Besides this guide is for this model ( SM-G9980 ). This model is 3G and 4G compatible in Canada and USA, 5G is not compatible at least for the moment, carriers use fewer bands for 5G. But who really wants 5G?? 4G is fast enough, 5G consumes a lot more the battery, not available in many areas....
[Samsung Galaxy S21 Ultra] oraned:
if i do root to s21u its There is an improvement to the camera?

or just for viper4 android?? What else is he giving me??
[Samsung Galaxy S21 Ultra] Amd4life:
Which snapdragon 888 version has bands 66 and 71 AND allows root;. SM-G998N(korea), SM-G9980(china) or SM-G998U1(US unlocked)? All the sites like gsm arena seem to detail that all the phones have the exact same LTE bands this release.

Can anyone confirm, they have use of bands 66 and 71? I don't really care about 5G.
[Samsung Galaxy S21 Ultra] jmac052002:
So what is B/N/O version...I have verizon s21+ us model can I do this ?
[Samsung Galaxy S21 Ultra] jmac052002:
Hey getting any closer on bootloader unlock for s21 devices?
[Samsung Galaxy S21 Ultra] Max128:
Look at my last post above, it's exactly the same thing for you. Short answer: No
[Samsung Galaxy S21 Ultra] afaneh92:
B: Intl variant, N: Korean, 0: Chinese.

Not yet for US devices, samsung made it harder on 2021.
[Samsung Galaxy S21 Ultra] rajc7:
Hi. With using this method do I need to start rooted s21 Ultra (exynos) using any special button combinations, or just normal startup? (just previously it was combination I think)
[Samsung Galaxy S21 Ultra] afaneh92:
normal boot
[Samsung Galaxy S21 Ultra] speedyjay:
I think I'll wait until their is a reason to root. Having no custom ROMs, no installable apps that take advantage of root privilages. The only things we have are Magisk modules - and while that's all well and good, it's not a justifiable reason to trigger Knox just yet.

Thanks for the work though @topjohnwu lol
[Samsung Galaxy S21 Ultra] destz0r:
Does rooting also remove the ability of getting official OTA updates?
[Samsung Galaxy S21 Ultra] rodrigofd:
Just my two cents, my own reasons to justify rooting via Magisk:

* Viper4android

* Change CSC features >> enable native call recording

* GMD Gesture Control app (native low level gestures, miles better than any non-root alternative)

* custom Gboard themes

* Custom font

* Custom themes via Substratum engine

* iOS emojis
[Samsung Galaxy S21 Ultra] speedyjay:
Out of all those suggestions, Viper4Android would be the only reason for me.

CSC doesnt really do anything for me, i can can call, text and use data....my phone works.

Gesture control...meh, the stock Android 11 gestures work just fine.

Custom GBoard themes....meh

Custom fonts....meh

Custom themes....meh, just another thing the phone has to load, thus decreasing performance.

iOS emojis.....just buy an iPhone if that's what you want....
[Samsung Galaxy S21 Ultra] speedyjay:
Saying that, root because of Viper4Android.....

Do i or dont i? Is it worth triggering Knox? Losing Samsung Pass etc
[Samsung Galaxy S21 Ultra] tiho5:
+1 (y)

Even only that is enough for me.
[Samsung Galaxy S21 Ultra] akira022:
Viper is the only reason for me to ever root. I have yet to find a non root way to crank the base up without sounding crappy. Knox isnt really a big deal with me as with my carrier they have a premium accidental insurance that is i think $12 a month and I have had some root flagged phones and turned it in to insurance with that. Still have to unroot though. Samsung Pass and Bixby is just annoying to me and just want to get rid of them. Cant wait to find out how to unlock the bootloader in the US now ^_^
[Samsung Galaxy S21 Ultra] Max128:
Well guys you have forgot the debloat (yes i know you can do it with a computer without root) but you can not modding the /system partition either.

I'm a little surprised why no one has talked about ad blocker like adaway? I love so much this.. Mainly in games, I have some free to play games that play online and without a ad blocker I would have advertising videos several times for at least 30 seconds each.. With it i can avoid all of this
[Samsung Galaxy S21 Ultra] rodrigofd:
To be fair, most of the reasons to root (including those I listed on this thread) have almost-good-enough nonroot alternatives.

Regarding ad blocking, there are some interesting alternatives, like using ad blocking DNS servers, you can easily configure on your network settings, on your unrooted phone (e.g. https://adguard.com/es/adguard-dns/overview.html)
[Samsung Galaxy S21 Ultra] Yescheb:
I rooted mainly because of adaway and viper4android.

Viper4andoid did not work for me. Has someone got it working? How did you install it?
[Samsung Galaxy S21 Ultra] ramkiller1:
Titanium backups works well? I want to restore from my old s7 edge
[Samsung Galaxy S21 Ultra] ramkiller1:
I'm having issues with getting boot.img . I downloaded the SM-G9980 CSC TGY, used 7zip found AP, used 7zip in that, in there i found boot.img.lz4 and vendor_boot.img.lz4. I tried both files for magisk and it didnt work. Even tried removing the extension .lz4 but still installation failed. What can I do?

Edi: Figured it out, trying to figure out how to get into fast boot mode
[Samsung Galaxy S21 Ultra] ramkiller1:
When I do this on the CHina variant. the OEM unlock is no where to be found after unlockin boot loader the first time

Edit: figured it out

REPLY
[Samsung Galaxy S21 Ultra] ramkiller1:
So I used the AP file, pactched it, reused it with odin with the other files, now my phone is in a boot loop , shows some red text to the top. I tried wiping but still boot loop

Edit : did a full restore on odin
[Samsung Galaxy S21 Ultra] ramkiller1:
How do you do " Rename magisk_patched.img to boot.img and use 7zip to make flashable tar of your boot.img " or get into fastboot

Edit: Used Odin
[Samsung Galaxy S21 Ultra] ramkiller1:
So I have done both ways with my China Variant, both gives me a bootloop. Not sure what to do now.

edit: Think i figured out why!
[Samsung Galaxy S21 Ultra] c2560242:
I saw yesterday s21 and now I can't get rid of thinking about selling mi10 I bought about half year ago.

What can you tell me about safetynet and google pay? Can you confirm it works fine after rooting?
[Samsung Galaxy S21 Ultra] xAD3r1ty:
What was the solution?
[Samsung Galaxy S21 Ultra] Psy87:
Does it kill ota updates?
[Samsung Galaxy S21 Ultra] Yescheb:
Does not work. I tried it for deleting bloatware as I did with my S7 but it did not work
[Samsung Galaxy S21 Ultra] Demon219:
thank you worked for me
[Samsung Galaxy S21 Ultra] ramkiller1:
worked for me
[Samsung Galaxy S21 Ultra] ramkiller1:
yes
[Samsung Galaxy S21 Ultra] ramkiller1:
I didn't use the correct version of Magisk.
[Samsung Galaxy S21 Ultra] afaneh92:
yes
[Samsung Galaxy S21 Ultra] c2560242:
Just to be sure. Magisk or unlocked bootloader kills OTA? And what about safetynet and Google pay?
[Samsung Galaxy S21 Ultra] afaneh92:
Magisk since it modify the boot partition. And safetynet can be fixed using a module.
[Samsung Galaxy S21 Ultra] c2560242:
I saw it is possible to relock bootloader on a50s. So if I restore original boot can I also relock s21 and restore knox, ota etc?
[Samsung Galaxy S21 Ultra] TheCoryGuy:
I have the SM-G998U1. Can I root it? Not sure what B-N-0 indicates for compatible devices.
[Samsung Galaxy S21 Ultra] speedyjay:
Unless you want a really expensive paperweight, i wouldnt attempt this. The B-N-O applies to Exynos variants of the S21 Ultra.

DO NOT ATTEMPT THIS IF YOU HAVE A US SNAPDRAGON MODEL!!!
[Samsung Galaxy S21 Ultra] Max128:
Lol transform the phone in paperweight when you are trying the root? This is impossible! ( is not the same thing like 10 years ago.) The worst things can be happening is a soft brick in boot loop and is easy fixable , only need the reflash the full rom ( including the firmware)..

The B-N-O applies to Exynos variants of the S21 Ultra. ≤--------- Not exactly true, the 0 variant ( SM-G9980 ) is a snapdragon 888 and the bootloader is perfectly unlockable and working with this method.
[Samsung Galaxy S21 Ultra] afaneh92:
Relock bootloader means to reflash stock firmware 🙃 and knox will remain tripped.
[Samsung Galaxy S21 Ultra] Clarkie_955i:
Hi

Seriously thinking on getting this model SM-G9980. But really want it unlocked and rooted. What is the procedure for unlocking the bootloader on this? Is straight forward as going to developer options and flicking the switch.

Thanks
[Samsung Galaxy S21 Ultra] c2560242:
Are you saying it is not similar to procedure on this movie?
[Samsung Galaxy S21 Ultra] msiafterburner:
Going to check this guide
[Samsung Galaxy S21 Ultra] Enddo:
here's a video tutorial (for anyone who is stuck)
[Samsung Galaxy S21 Ultra] Max128:
Yes is easy like that, enable the unlock OEM in the developer options after this you can unlock
[Samsung Galaxy S21 Ultra] Enddo:
what's the process of passing safetynet checks?

I'm currently showing as the hardware-based check failed
[Samsung Galaxy S21 Ultra] Clarkie_955i:
Thank you.

This is a big relief. Was very uncertain about going to a phone that can't be rooted.

Cheers

[Samsung Galaxy S21 Ultra] SeanGold:
I had a question I hope someone could answer. I'm a photographer and would really like to have RAW access to all the cameras, front, tele, wide and main. Is there currently a way to do that if the phone is rooted or is RAW access hardware locked or something like that? If so, I wouldn't root at this time as that is the only real thing I'd be looking for. Thanks in advance.

P.S - How annoying that Samsung locked RAW access to the cameras. Android is supposed to be open, even Apple gives raw access, what nonsense.
[Samsung Galaxy S21 Ultra] pisaman2:
I've successfully followed this guide, and all appears well so far with the exception of the fingerprint sensor in apps, such as my banking one. It does however work for simply unlocking the phone

I seem to get an error when trying to set fingerprint reading up in these apps. Is this due to knox being triggered, or does it sound like anything else?

Also, has anyone else experienced this?

Edit:

I seem to have fixed the issue. I traced it down to being related to the safety-net magisk module I had flashed. It turns out there seem to be known issues with it, and have been resolved in a test release (version 2.0 I believe)
[Samsung Galaxy S21 Ultra] Bec07:
This does work in Magisk only, not the Play store and breaks fingerprint authentication in apps.

try this instead:

Shim the keystore service instead of replacing it by kdrag0n · Pull Request #13 · kdrag0n/safetynet-fix

This method is more portable, does not require a different executable for each Android version, and avoids breaking ROMs with heavy keystore customizations. It works by injecting a shared library i...

I'm a little confused I ordered the I locked version direct from Samsung so will this be the SM-G9980? I really want to be able to root it when I get it if not well it may go back to Samsung.
[Samsung Galaxy S21 Ultra] GrandMstrBud:
Thanks
[Samsung Galaxy S21 Ultra] NippleSauce:
It just depends on where you live. If you live in North America, you'll pretty much end up with a Snapdragon phone no matter what (and therefore, you won't be able to unlock your bootloader for free or permanently). But if you living anywhere else, then you get an Exynos version of the phone (or an unlockable Snapdragon phone) which you will be able to unlock the bootloader for free and permanently on.

But either way, you'll need to unlock your bootloader in order to root your phone.
[Samsung Galaxy S21 Ultra] GrandMstrBud:
I know this but this thread said US and Canada and

I know this but it says US and Canada and the U1 model which is the US unlocked model I believe.

Yes but we are talking about unlocking bootloader for US and Canada devices.
[Samsung Galaxy S21 Ultra] babyboy3265:
Totally agree with you! AFWall is a life saver!! I had not heard of Xprivacy until i read your post! One more big reason for root indeed! Now I just have to figure how to use the xprivacy app with its hooks and restrictions.. Those seem hard to understand from the descriptions in the official page :/
[Samsung Galaxy S21 Ultra] babyboy3265:
Massively agree... I just installed TWRP on my phone and got the rooted KETAN rom on it. I will be installing the Xprivacy app asap because I'm also paranoid about these permissions, especially given how important our phones are today and how much stuff they store.

FYI, I have been setting up AFWall and was struggling for a while to minimize the notification in the panel and also remove the shield icon from the status bar. Fixed it by going to the settings of the Afwall notification. Then FIREWALL SERVICE, and toggled "Silent" and "Minimize notification". Now the app is still active in the background but does not appear on the status bar all the time and it still gives me notifications if I install a new app.
[Samsung Galaxy S21 Ultra] SnowFire:
If I have a s21 ultra model provided by vodafone germany, can I also use the DBT firmware instead of VF2 when flshing the firmware files with magisk and odin later?
[Samsung Galaxy S21 Ultra] afaneh92:
post model to get more clear answer
[Samsung Galaxy S21 Ultra] SnowFire:
I got the model g998b/ds with VD2 software on. My question was, if I also can use the DBT firmware with its bootloader for AP, BL, CP and CSC?
[Samsung Galaxy S21 Ultra] afaneh92:
Since you have unlockable bootloader why to not patch the firmware again.

Its better to be on the same firmware and not to mix them.
[Samsung Galaxy S21 Ultra] xfilemanx:
Why is this so difficult to make happen?!!.....

This method is the same method I keep finding, and I've been looking all over the net for the last 24 or so hours, and it does NOT work for my SM-G998U and NO I will not be paying anyone to do it for me. That has got to be the biggest load of crap I've ever seen. Does no one know how to do this or what, besides the people "selling" their services.
[Samsung Galaxy S21 Ultra] afaneh92:
Because its not free, if I can get it for free then you can use it for free. If you dont need it then dont use it.

I cant confirm a time for unlock, you can wait or replace it with v1 bootloader. Or get yourself a HK device if possible.

[Samsung Galaxy S21 Ultra] elliwigy:
You either want to use the service or you don't, its that simple.

He has told you why theres a charge.. the unlock tokens are device specific and have to be purchased so there is no way to provide it for free.

If the service wasnt an option you would come to usa/can device threads and see NO development whatsoever so that being said there is 100x more development now because of the service.

I understand some wish everything was free but you cant expect us to spend money out of our own pockets to unlock everyone do you?

Just saying it is what it is.. source charges per unlock so we have to charge per unlock. There isnt anyone I know that can make tokens else it would be well known and posted for free but it simply isnt that way. No need for making accusations about others trying to "make money" because I assure you its not very lucrative.

Also, we have contributed "for free" for years (myself over a decade) and continue to contribute for "free" so to say he is in it for money is just not true.

If you dont agree with the service or dont want to pay for it then thats your decision, no need to go at the dev for something out of their control for providing an option that wouldnt otherwise exist.

Thats my opinion anyway lol

I have a HK device with a "G980ZHU1****" build number and before attempting to root, I noticed that it wants to do an OTA update to a "g9980ZHU

2

****" -- does this mean that if I let this OTA happen, I won't be able to unlock and root?

I was thinking of first installing this OTA, and then rooting afterwards, so I have the latest version after the root. But is it a bad idea then? Or is the HK version 2 also rootable?

PS: How and when can I do the update then? Never? As far as I understand it, if you update you loose root, but if updating to a version 2 will lock the bootloader, then am I stuck with my current version of the OS?
[Samsung Galaxy S21 Ultra] afaneh92:
HK devices are ok you can update to any firmware, we were talking about US devices.
[Samsung Galaxy S21 Ultra] afaneh92:
We can unlock only v1 bootloader on US/CAN
