Is SM-N981U Able to be Rooted? - Samsung Galaxy Note 20 Questions & Answers

I'm pretty sure the answer is no but does ANYONE know if I can root my SM-N981U? I did get the recent updates automatically and I'm currently running UI v 3.1, bootloader v 2 and android 11. If its NOT possible does anyone know if anyone's working on it? Any help would be AWESOME!! I also have no idea how to turn the bootloader off if rooting is possible so help there would be nice. Thanks in advance!

Your model number ends with "U" which indicates that it's a U.S. variant
U.S. variants always get their bootloader hard locked and can't be unlocked via regular means. Root requires that you unlock your bootloader.
There was a paid service that offered to unlock U.S. variant bootloader here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
But I'd ask first if I was you. Other than that, I don't think you'll be able to root.

Bootloader Unlock info for S6 Edge? Only with Unlocked bootloader we can root?

Can we get a thread to consolidate information about the locked bootloader?
I need root, and waiting for an exploit to root might take a long time (or never), so the only other option is to get the phone unlocked?
Is the manufacturer able to unlock the bootloader? Is there a way to splice a root into a factory update?
SIM unlock and bootloader unlock are totally separate, so none of the 'unlock' services frequently advertised will be able to unlock the bootloader?
I'm am seriously frustrated by not having boot access, to the point that I am considering selling the phone and getting an HTC or Sony.
What really sucks is I bought this phone off-contract directly from Samsung because I thought only Carriers phones had bootloader locks.
FYI my version is the SM-G9250 (Asia spec phone).
That sucks.
I recommend you return or sell it and buy a T Mobile S6 or S6 Edge. After 14 days of purchase, they will unlock the phone. Also, it comes with unlocked bootloader and root is now available.
How do you check if bootloader is locked or not? I have an international version (F).
Thanks

Liking this phone more and more...
Unfortunately I spend most of my time in Asia, so I don't have much of a choice. This phone has more coverage...and there is no cooling off/return period in Taiwan. I can only sell it as a used phone.
So the T-Mobile us version comes with an unlocked bootloader? This is the deciding factor of me purchasing this device .

This is amazing. I never knew T-Mobile did this. What's the protocol for unlocking after the first 14 days?
I think its 40 days, or something similar
just call them and ask them, they will tell you exactly how you do it
I'm from other country holding the G925I version
how do I check if the bootloader is locked or not?
I'm So EXCITED! Samsung provides factory bootloader unlocking!
I posted the details here:
http://forum.xda-developers.com/gal...o-bootloader-unlock-s6-edge-sm-g9250-t3086325
Is the boot loader in the Hong Kong version locked too?
Hiya, does anyone know if the Canadian version (SM-G925W8) comes with a locked bootloader? I'm trying to root the device but it just keeps failing in odin.
According to this, the latest update for T Mobile locks the boot loader guys. http://forum.xda-developers.com/showthread.php?t=3096169

Just bootloader unlock won't help for the carrier branded models. Here's why... the T-mobile LG G6 already has bootloader unlock, but LG removed all the other ADB flash commands. So, bootloader unlock is useless on the T-mobile LG G6. Six months later, still no root, no TWRP custom recovery. It's like having the keys to a new car but the car has been melted down to block of metal. The keys are useless.

Some more information on the T-mobile LG G6 from an expert:
autoprime said:
T-mobile H872 G6 doesn't have root yet and will only have root once they have a method to get TWRP onto the device. Fastboot boot/flash commands are disabled so it will take an exploit of some sort to get TWRP flashed to the recovery partition.
The only other G6 device that will have root is whatever device LG adds to the official bootloader unlock list which can be found here: http://developer.lge.com/resource/mobile/RetrieveBootloader.dev?categoryId=CTULRS0703
The models added to the bootloader unlock list will be the models to get for proper bootloader unlock, TWRP and root without jumping through hoops like the Tmobile H872 variant does. (currently U.S. and European unlocked carrier LG G6)
For all the other G6 variants without bootloader unlock (AT&T, Verizon, us cellular, canadian, australian, south american, korean, chinese, etc..), a new root method of some sort would be needed but there is nothing public yet. Once a public root arrives and if a debug bootloader image is leaked (like the LG V20) then other G6 variants might be able to have an unlocked bootloader allowing TWRP and permanent root.
Just laying out all the current info to this date. I have no plans to work on any of this as I do not have the device.

Even if you could unlock the bootloader to the other carrier-branded models, LG has probably removed the ADB flash commands from those phones as well? Only the official carrier unlocked versions are eligible for REAL bootloader unlock, the way you are thinking about.
Look down in the development section here for the official carrier unlocked LG G6 (which is eligible for REAL bootloader unlock with ADB flash commands present). TWO pages of ROMs, kernels, custom recovery.
Yet, over on the "bootloader unlocked" T-mobile LG G6 forum, there's 23 pages of root begging thread, which has now been abandoned as a lost cause.
Not only would you have to get bootloader unlock from LG, they would have to add back the ADB flash commands -- or a dev find some exploit to get TWRP custom recovery installed. And that's not been possible yet on the T-mobile LG G6, even though it's bootloader unlocked!
If you are interested in dev stuff for your phone, sell your LG G6, and get one of the official carrier unlocked models -- either the LG G6 or even the new LG V30.

For the carrier-branded models, yeah probably no hope.
My point is LG will say if you are interested in REAL bootloader unlock, they already provide that for the official carrier unlocked models.
Removing the ADB flash commands on the carrier-branded models was very devious "security" method so that cracking the bootloader on carrier models with an exploit (like Dirty Santa) still wouldn't do any good.
With the T-mobile LG G6, devs have has six months to try to find some method of installing TWRP on that unlocked bootloader and not been successful. They may do it some day, but when? Meanwhile the carrier unlocked models have bootloader unlock AND ADB flash commands. If you were a dev, do you go through the already open door or try to break through the brick wall?
Decided to sell my G6 and switch to Samsung after this twitter reply from lg.. this will be last lg phone i bought until they let us unlock bootloader or anyone unofficially unlock..

Why? They said that they don't make the policy of what to unlock.
LG provides two phones that are unlocked and you can develop on.
Most carriers do not want you to have a rooted phone.
Samsung has KNOX which is even worse. If you try to root the phone you can trip KNOX and brick the device.
Samsung does not unlock devices unless you buy a, wait for it, developer version.
HTC is fairly easy if you find someone to S-OFF the device. But that's not HTC.
Mototola will not unlock the bl on branded phones. On other phones it's hit or miss.
LG with their carrier unbranded phones and Google seem to be the most supportive.
If you buy a Pixel from Verizon, the BL is locked and you can't unlock it.

Glad you found a solutions.
IT varies from country to country and sometimes I forget that.
Here in North America (US and Canadian carriers) getting a Samsung unlocked phone just isn't normally possible.
You can't get a version that supports North American LTE with a boot loader you can unlock.
LG and HTC along with Google phones that are unbranded usually can be unlocked here.
Never buying or getting an lg phone ever again...not even for free. Biggest mistake I have ever made...

Can we start a petition to at least unlock the boot loader for Non carrier branded G6 versions ?
I am losing more and more confidence in LG on supporting our device after their concentration on V series and branding change for G series.
We definitely need software support to our phone to justify all the initial hypes and the money we spent.
Please clear my mind, if someone is officially unlock the bootloader for LG G6 (H870 or US997), then the phone will just lost the warranty. So LG will deny the device.
Than why the other types has not got the possibility to unlock.
If they do so, then we (customers) will have just one way - not to buy phones from them in the future.
Hello,
I just started the petition "LG Electronics: Unlock boot loader for all variants of unlocked LG G6 Smartphone" and wanted to see if you could help by adding your name.
My goal is to reach 100 signatures and I need more support. You can read more and sign the petition here:

Same pinch.
I am coming from LG Google Nexus 5x and I am already suffered a lot for coming out of Nexus line.
I assumed that we can at least Install custom firmware and can be in the bleeding edge.
But LG has prevented that as well.
I would also never buy an LG Phone again.

You need the right file sent by LG because content of the file depends by your IMEI and Device ID. Each unlock.bin file is unique.

Same here. I don't do much dev work or CFW now, but I hate that it's not even possible with this variant. I owned a Google Nexus 6P that started having battery drain issues at just over a year. Nexus Protect will send you another phone for $75, but since they refuse to acknowledge that the battery issue exists, if it starts having issues, they expected me to pay $75 to get another defective one. No thanks.
This phone can't be unlocked, but I suppose I'm just thankful that it doesn't drop to 20% battery in 2 hours and then shut off 10 mins later!

Will a Rootable Android Phone Remain Rootable After Flashing a New ROM

I searched for this question, and couldn't find one detailing exactly what I intend to be asking. I am going to be getting a Samsung S20+ SM-G9860 so that it would be rootable. However, after I get the phone, I intend to flash the AT&T ROM to it so that I may use my carrier specific features. Will the phone remain rootable after doing this?
AFAIK AT&T will not have ROMs with an unlockable bootloader.

So even if the device itself has an unlockable bootloader, the AT&T ROM will not allow it? If so, then that's very unfortunate.

My previous post was erraneous: sorry for this. :crying:
The correct answer is:
Once a device's boot-loader - it's like the BIOS in the PC - got unlocked you're able to root it. Some manufacturers provide a boot-loader unlock tool for certain models of their phones.
If you are able to modify device's boot-loader - means unlock it, then in turn you are able to load whatever Andoid OS you want (clearly and obviously, as long as it works in that device) and root it.

S21 Root?

Hello. I'm new to rooting and bootloader unlocking. I have read numerous guides on rooting the S21, and when it gets to the stage where you enable OEM unlocking in developer options, it doesn't show a setting. Maybe someone could point me in the right direction because I have no idea where to go. This is a Snapdragon model on u1 firmware.

Cannot root these without paying someone $150(ish) to unlock your bootloader.
On the 9910 model - designed for China, Hong Kong and Taiwan, you can unlock the bootloader just like on models with Exynos.
In the model for the American market, it is necessary as described above.

Question Unlocked vs T-Mobile version questions.

I currently have both the T-Mobile version and I purchased an unlocked version from BestBuy.
https://www.bestbuy.com/site/oneplus-nord-n200-5g-blue-quantum-64gb-unlocked-blue-quantum/6468089.p?skuId=6468089
Are there physical differences to these two phones or are they just running different software?
EDIT I looks like its not possible to unlock the bootloader of the T-Mobile version just yet and I have been doing some searching and it looks like the unlocked version is closer to being unlocked. If anyone can confirm a way to bootloader unlock either I would appreciate it.
My end goal here is to get access to Unlocked/Uncapped tethering without having to use a 3rdparty app or companion app. The ability to flash custom ROMs and root access. But also the ability to flash back to a 100% stock rom.
Any help or advice is greatly appreciated.
EDIT I see now you can get the bootloader unlocked on both version by sending a token to Oneplus and waiting 7 days.

The only physical difference is that the T-Mobile version has the IMEI engraved onto the back of the phone while the unlocked variant does not and the original boxes are slightly different.
Both phones run different software. It is possible to flash the unlocked ROM to the T-Mobile version of the phone after unlocking the bootloader, but that breaks OTA.

I'm trying to do the same thing with the N200 for a hostpot @xVoidx . I'm curious if you succeeded, and what ROM did you end up using to do it?
