[CLOSED][Android][UNSAMLOCK] Bootloader Unlock for Samsung US/Canada Devices

[afaneh92]

Is there a way to tell in advance if i'll be able to unlock an 988U1 (S20 Ultra) or 998U1 (S21 Ultra) prior to purchasing from Swappa? What should I ask the seller about prior to purchasing?
Thanks!

bootloader version must be 1 for both, 5th character from the right on build number.

If you can you should get g9880 (Chinese) rather than g988u (usa)

Do they have the same/similar band coverage?
The G988B international is missing some bands used in the US.

Is the BL version listed anywhere in settings? If not, what do I ask the seller to do in order to find the BL version?
Thanks!

Any respectable cell service will give you the band's you need, if you need 5g rather than lte they should provide it.

Settings > about phone > software info
Take screen shot and see the 5th character from the right on build number

NOTE: The OneUI 3.1 bootloader (march security update and later) will bypass the unlock token, Do not update or bump your bootloader version. So If you ever take the update and you can downgrade go for it. And you will remains unlocked.
NOTE2: Device Shipped with One UI 3.1 like S21 can be unlocked on V1 bootloader. A32, A43 and A52 5G with V1 & V2 bootloader.
NOTE3: Im not a part of sampwnd so dont conflict between us.

Disclaimers:
Please note that unlocking your bootloader does not mean that you will be able to unlock the SIM lock. Unlocking your SIM lock is at the discretion of your operator/carrier and is not part of the bootloader unlocking scope.

We strongly suggest that you do not unlock the bootloader unless you are confident that you understand the risks involved. This is a technical procedure and the side effects could possibly necessitate repairs to your device not covered under warranty. If you are still interested in unlocking the bootloader, and you understand the consequences both to your device and to your warranty, then you may refer to the following post where we have provided the unlocking instructions.

Gotta get root for n986u1. All phones since my note3 have been rooted. Now that v2 bootloader is locked, is there a realistic chance that an unlocker will be developed? Is it just a matter of time where a solution is figured out?

Your effort is much appreciated

Firmware N970U1UEU6FUC6, 6 bootloader suitable for unlocking Note 10? There is an inaccuracy in the description on the site.

Why is the only option a non-refundable PAID service for unlocking the bootloader?

I thought the point of XDA was members publishing methods for doing this kind of thing? I've been an XDA member for years and this is the first time I've seen a thread like this where it's a paid service.

Its a in-demand service that has had hours of research and troubleshooting. Why wouldnt it cost something? Took effort to produce.

Lol, okay. 99.99% of the stuff on xda is about community effort. What a shame.

Samsung screwed over US phone buyers by locking the phone down like they did.

The unlock costs money, cause they people unlocking the phones here... PAY to get the unique code to then SELL to you. Again due to Samsung.

Yes it's BS. But it's Samsung's fault we have to go down that path, not the two doing the unlocks for us.
