Unfortunately the SM-S908U1 cannot have its bootloader unlocked normally. Unless there's some other method or exploit, it will be locked forever.

There is an exploit out there. It has been in the news lately. It is whether or not it actually ever makes it to anyone that can use it to root our devices. But it does work for the s22. Here is an article about it.

Hope this comes to us, I feel like I just wasted money twice... I also have sm-n986u from ATT... Can't unlock that bootloader either for root

Only Exynos and a couple of Snapdragon variants offer bootloaders which can be unlocked. A little research goes a long way.

I did my research before I got the phone... and even on this site had a method for my snapdragon model

This is the link on XDA for root on the S22:Ultra. Only models ending with B, E, N and 0 are compatible but don't give up hope, XDA has some world class developers who might offer a workaround.

for now, I'll disable my software updates for android and wait lol.... Root became available for my note 20 ultra after some time, but I had already installed a later version that was patched....

That’s why I ended up spending the money to buy the international version rather than the US\Canada versions knowing that there is a lot of network incompatibilities. I need the bootloader to unlock and root.

This looks very promising... Should be able to transfer root files even without trippin knox? Seem like that concept would fix the issue...

Same case here as OP. Hoping a workaround comes up!

Ditto, here. I'll keep checking back. My 3T was un-rooted for a while, until the ads started getting worse... Gonna really miss AdAway and Vanced.

Still no bootloader unlock for a SM-S908U1? Its time for me to start writing kernels again!!! Tired of no customization and bad battery.

How are you disabling updates? My att 908U just randomly updates without me allowing it. Really annoying. It does it when and where it wants to. I don't like them having such control over my phone.

SM-G955W Oreo Root?

Hello everyone, I've been looking to root my S8+ G995W on 8.0 oreo for a while now, but I haven't had any luck.
I previously traded my oneplus 5T for this s8+, and according to the receipt provided to me it was from Koodo and it's unlocked (not sure if koodo unlocks bootloaders though). I've looked through the developer options and I see no OEM unlock option, and I also had a friend try to run me through a couple things with fastboot to unlock the bootloader from there, but we've had no luck.
If anyone requires more information to help me out, please do let me know
I've decided to turn here as my last resort, hopefully there is someone that has been in my same spot and knows how to root this variant, thank you!

When a carrier says that the phone is unlocked, they're saying that it's SIM unlocked (not bootloader unlocked).

G955W is the Canadian variant with the snapdragon chip, snapdragon = no bootloader unlock. The only model you can unlock the bootloader is the international variant with the exynos chip (and carrier don't have them).

As of right now, I don't think that you can root with oreo. The only way that I'm aware of is this method but it's on nougat and you have the 80% battery limit.
If you really wanted to play with rom, mods and everything, you should have kept your 5t.
Hope this helps.

Question New, unopened S22 Ultra - Is it rootable?

Hi - We just received a brand new S22 Ultra, and I haven't powered it up.
I read online that the S22 Ultra was rootable if you didn't take any updates (There was mention of KingoRoot, which I would prefer to avoid for security).
Is there still a (safe) root method available for the S22 Ultra?
And if "yes", would somebody please point me in that direction?
Thanks!

If you mean is there a way to root without losing warranty? No, you will lose warranty if you root from my understanding (there are trips that cannot be reversed). But someone more experienced can chime in, they might know better.
Warranty Schmarranty!
No, by "safe" I want to make sure I don't have to follow 43 cryptic steps (18 of which are missing), hold my crotch, spin 3 times, spit behind my computer, turn the phone back on, only to find that my brand-new phone is permanently bricked.
Oh - and not use KingoRoot, since I remember that they were pretty dicey as far as whether they may be installing malware onto your device.
Depends on which S22 ultra you have. The United States Snapdragon is not rootable..no bootloader unlock. Would help if you gave more info about your device.
I got mine earlier, hoping it would have one of the big exploits they'd been talking about. But unfortunately, it arrived with the updates that patched them preinstalled. Sold it and bought an oversees one.

Sorry, about that - I didn't know that there are two models of the S22U. It's the first Samsung phone I have purchased in over a decade, I didn't know that they do that.
I got it for a pretty decent price on an Amazon Prime Day deal. I didn't have much time to research about the S22U before buying it (other than the many good reviews). I was planning on getting a Pixel 6 Pro originally, but it was a mixed bag so I didn't go that route.
I had read online that it was rootable during my quick searches, I didn't see that it was only applicable to the global version.
There's about 6 or so models of the S22 Ultra. The US versions are not rootable, nor will they be.

Sadly no, they never will. And I feel your pain. I had a Note 10+ that I would have abused the **** out of if it had an unlockable bootloader.

I came across a defcon presentation called,
"Breaking the Android Bootloader on the Qualcomm Snapdragon 660".
It would appear that it is certainly possible to bypass a locked bootloader, Two interesting methods that were mentioned,
"The most commonly used approach is to access Qualcomm Emergency Download mode. This is a low-level emergency state boot mode, where diagnostics tools can be used to upload a signed “loader” payload to the chip, which can be used to modify the device’s partitions directly. While this approach is effective, it requires the ability to boot into the mode, which is not always made directly available to users, and access to a signed loader ELF which may not be available for the device.
The second common approach is to attack the device at a hardware level. By disassembling the phone, and connecting to EMMC chip on the board, it is possible to set the “unlock” bit in the configuration partition and gain unlocked access. Public resources exist which outline which pins should be connected to, however this usually requires some hardware knowledge and steady hands. There is also a high risk of irreparably damaging the device."
The rest of the presentation explains how the bootloader lock was bypassed via an exploit.
Ive also heard that exploiting flaws in Qualcomm's chips has become a common way to root bootloader locked devices, If root is all your after.

Question Anyway to root without paying anything?

Be honest with me. Is there ANY way to root my A326W without paying a single penny?
yes? just follow the offical documentation and you should be fine
What about SM-A326U ?? Any free root method or any ROM at all release for it ??

Oem unlock is missing and the only way to get it back without paying anything doesn't work for me.
did you buy your phone recently? there's a 7 day period where you can't unlock on some android phones

No, and it's been more than 7 days.
No way to root for free unfortunately, Samsung locks down their US/Canadian phones real hard, probably at the request of certain cell carriers.
Wish I could root my S326DL as well, Tracfone model.
I don't even think you can root the USA T-Mobile Samsung Galaxy A32-5G (SM-A326U) for payment, can you?
The only "unlock" you can do is the network unlock (AFAIK).
I don't think the boot loader can be OEM unlocked, can it?
I tried the paid method and they said that they could not root the phone.

Possible to Downgrade From Android 11 to 10 on XT2113-2? If so, how?

I have a new XT2113-2 (TM) that is yet to be boot loader unlocked/rooted/etc. I don't want to do that until I am sure. I got this variant of the phone so I could unlock the bootloader, root, TWRP, etc and was afraid the "global" variant -3 might not work with USA 5G. The phone came with Android 11 installed (and has since auto-installed at least one security update). It shows the build as RZKS31.Q3-45-16-3-11 and the baseband ends with Kiev_TMO_CUST. I am using it on ATT (via Red Pocket) since TM service just sucks where I live. And I do get the 5G icon on it now.
But ideally, I want to get this to the original TM Android 10, which I think is shown here as the file XT2113-2_KIEV_TMO_10_QZKS30.Q4-40-95-6_subsidy-TMO_SPR_RSU_QCOM_regulatory-DEFAULT_CFC.xml.zip as I hope it will undo some of the "security" crap Google has added to Android with each successive release.
So I need to be sure of the following:
1. Can I downgrade from 11 to 10?
2. Is there some reason to NOT use the firmware mentioned above? Should I use retail US (RETUS) instead? I am not sure the differences (it would be great if that would permit me to use this phone on Red Pocket Verizon but the IMEI now shows as incompatible on Verizon).
3. Must I unlock the boot loader to downgrade? I know I must to do other stuff and I have the unlock code on hand and ready to put it if needed. If I must unlock the boot loader to downgrade, will I have to re-unlock it afterwards? And, if so, will I have to go through the same process of getting a code or will the code I have now work?
4. How do I flash to do the downgrade? I have the Lenovo Rescue/Smart Assistant installed on my PC and was able to download the stock firmware (I assume it matches what is on there now) and stashed it aside. But is there some other tool needed?
5. Once I achieve downgrade, what is the best way to avoid having the thing auto-update to Android 11?
Thanks for your help with these questions.
If you are going to take this phone to AT&T, you will not get 5G if you unlock the bootloader. The NR band will be restricted. Downgrading from 11 to 10 generally doesn't work either.
I can't answer the rest of your questions.

Thanks for this response. I do have it on ATT (via Red Pocket) now and it does appear to get 5G now. I have not yet unlocked the bootloader, was thinking to do it, but considering that it would cause loss of 5G I think I will not and will just return the phone. Wow!

BTW - have you any references on this behavior? I am wondering if this is something that would affect ALL phones with unlocked boot loaders (like Pixel, OnePlus, etc). Thanks for the heads-up.
WARNING: ONLY DO THAT IF YOU ARE REALLY SURE AND DO BE CAREFULLY. I recommend you: do it not.
By downgrading to an older software, the bootloader in many cases can be destroyed, so your phone is completly bricked!
I write this from EXPERIENCE. My amazon fire is completed bricked, when i have flash a older SYSTEM. It can't turn on, no fastboot, no recovery!

I suspect, but don't know, that all phones with unlocked bootloaders are blocked from 5g from AT&T. I know my kiev (RETUS) is.

Thanks. Yet another reason to dislike ATT, I guess. Sadly, in my area TM coverage stinks. And this phone will not work on Verizon (unclear why but they reject the IMEI). And getting the Verizon variant will preclude ever rooting the thing. So I really feel trapped!

I always figured it was this
English Community-Lenovo Community
as my IMEI SV on the Metro/TMO variant is 05 rather than 07. Never tested with a locked bootloader though.

Bootloader unlocked Pixels work fine on ATT 5G, don't know about OnePlus.
