If anyone has a Samsung with 5G that has already been unlocked and are looking to sell it, please pm me. I can't seem to find the right phone, with the correct firmware, to purchase anywhere.

NOTE: The OneUI 3.1 bootloader (March 2021 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 5G with V1, V2 & V3 bootloader.
NOTE3: Im not a part of sampwnd so dont conflict between us.

Description:
This service will acquire you to unlock samsung bootloader. Allow you to flash custom firmwares, kernels and recoveries. This service will wipe the device entirely of all data, please remove your SD card, and backup all information that you may need, remove all accounts before service.
This service supports all current models that require token to unlock bootloader (e.g. US/Canada A51, A71, A32, A42, A52, S9, N9, S10, N10, S20, N20, S21, Fold, Flip and Tab series.)
DID is available on download mode or by ADB (adb shell getprop ro.boot.em.did) or by Android terminal (getprop ro.boot.em.did)
Provide the DID that you’ve obtained from the device (PLEASE DOUBLE AND TRIPLE CHECK IT’S CORRECT, THERE WILL BE NO REFUNDS FOR BAD SUBMISSION)
We will provide the token file once it’s available

FAQ:
- This is a paid service and not provided by XDA.
- Each device has it’s own DID and token.
- You cannot flash unlock token 2 times, you get a single chance, Dont lose it by flashing combination token.
- The token file will be available within 1–36 hours of order.
- We will unlock the device remotely or you do it yourself.
- To flash this token file yourself you will need a modified ODIN version.
- USA/Canada devices has no oem unlock toggle.
- Knox will be tripped after a custom binary flash.
- Samsung Pass, Samsung Pay will never work after root. Safetynet, Samsung Health and Secure folder could be fixed.
- This is a permanent bootloader unlock. You can flash full stock firmware (with the same bootloader version) multiple times and bootloader remain unlocked.
- Updating to 2021 march security update will bypass the unlock on most devices, don't update to higher bootloader version.

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.
Pretty sure that there's no way to revert back to a previous Bootloader version..

Afeneh92,
I used your services here on my 1st S10+, Verizon model. Worked great. I now have an unlocked model, 975U1. I updated to latest firmware that can be unlocked, v4, Feb 2021. My quesstion is, i want to unlock this phone and install the AIO for TWRP and Magisk, but i want to flash the Verizon firmware on it. Should i use your service 1st now to unlock, then safely Odin to the Verizon v4, Feb 2021 firmware? Or is it possible to crossflash from this unlocked to Verizon v4 with a locked bootloader and not brick, and then use your service? Thanks for any advice.

Current firmware can converted to Verizon by changing csc after unlock, and doesn't matter the order.

That explains why only a hand full of people know how to unlock it.
If they would tell the public how to unlock bootloaders, public would have already figured how to unlock bootloader v9
They cant unlock V9 so their paid service is useless for most people anyway and yet they keep it posted.
Explains what exactly? And yes, only a handful of people do know how to generate tokens and unfortunately they are not xda members and do not share their methods and only sell tokens so unfortunately its all we have to even have the option if ur device is on eligible firmware..

and yes, it is still posted bcuz ppl still have devices on older firmware that they want to unlock. Just because some ppl have updated devices doesnt mean everyone does. Its just the nature of the game.

Its also been commonplace for years now if you get a samsung and want to hopefully root one day that u dont do regular updates.

Right so I took another look at the list. It doesn't show the firmware baseband versions that can be unlocked. Just the models of device. This is becoming a chore to find a SM-G986U/U1 that can be BL unlocked. Seems all the devices are newer and updated on the market and sellers wont give me info on Ebay. Only that one seller from different site which was a updated device. I've already gone a week without a phone now since S5 G900V died. What do you suggest I do? Any good place elsewhere I can look? I've tried Swappa and Ebay seems like big corporations selling updated phones.
sad.. i just traded in a bootloader unlocked g986u lol

Well yes - That's what I was saying 😉
his wording isnt the best as saying "bootloader version" can be taken as bootloader rev lol.. but yea, long as its same rev ur good as in I can go from android 12 rev4 bootloader down to android 11 rev4 bootloader on my g998u1 is what he meant

I think that there used to be an XDA Marketplace - But not sure,
a) if it still exists.
b) why if you're trying to sell your phone, why wouldn't you just use a more local sales site. ie: in Canada we have Kijji.

bcuz if someone on xda wants to buy it then local sale wouldnt help lol would need to post to swappa or something then have them order lol
