Unlock Samsung Galaxy Book2 (Qualcomm Snapdragon 850 ARM64 Windows 10 Desktop Device)

Hey folks,
I've got a brand-new Samsung Galaxy Book2 device. Great tablet, runs full Desktop Windows 10, including x86 emulation, and native ARM64 compiled app support of course.
The party ended when I found out its locked to AT&T.
I'm even an existing AT&T customer but their unlock request process didn't recognize the IMEI of the device, so I wasn't able to follow through with it. I have no contract and paid full price for the device so I'm already eligible for the unlock.
Having inserted my AT&T SIM into the device, their app didn't manage to read my cellular line number, instead displaying garbage.
Please see the attached screenshots. I circled the region where my cellular number displays as garbage. Disappointing to find such a buggy app inside an otherwise excellent hardware product and platform.
Does anyone know how to work around this buggy app to unlock the device? I'd really rather not have to return it...

I'm having the same issue.
For anyone reading this, if you bought a Samsung Galaxy Book2 Windows 10 (ARM) tablet (**SM-W737A**), there is an issue with AT&T customer support not knowing how to unlock these devices. If your Book2 has **arrived** from Samsung within the past 15 days you should go ahead and return the device as it will take a while for AT&T to figure out this mess.
##Issue
These devices are being shipped network locked to (AT&T) and they lack the internal documentation for the customer service agents to unlock them. These devices contain a **Qualcomm X20 Gigabit LTE** modem that requires a code to be entered by the user of the device before it can be used with a different carrier.
##Example
I bought my device from Samsung.com and it arrived a month later. This device is fully paid off. **This is not a subsidy or contract device**. When it arrived, the modem won't allow for me to use it with a FreedomPop sim.
[The device needs a password to unlock it.](https://i.stack.imgur.com/ws7aR.png)
[But AT&T thinks that its already unlocked.](https://i.stack.imgur.com/x6p2S.png)
##Problem
Calling advanced technical support does not help. (I've tried 10 times, each time taking over an hour for them to help). They think this is a problem caused by Samsung. As their system says that its unlocked and their documentation says that there is no code to enter to unlock it.
Even going into an AT&T store and having a store manager call customer support does not work. As AT&T is very rude to their own employees and doesn't believe the store manager as well. The documentation that the customer service agents have on this new and uncommon device is wrong.

Does anyone have an idea to solve unlock at&t the device?

Solution?
Hey Bro, did you found an solution for this device already?

Unlocked CDMA Variant?

I have looked around and can't seem to find a model that is cdma compatible with sprint that has the ability to unlock the bootloader. Seems the A505U carrier variant can't unlock the bootloader. I've tried doing the 7 day trick but it doesn't seem to work for the A505U sadly(looking for additional confirmation on this).

Also on the look out for this, but it's not looking very promising. ?

I wish there were an unlocked varient for the US i just purchased one and didnt realize till when i looked at the model number that its for Europe

So the Sprint model can not be unlocked and rooted? I haven't owned a Samsung device for several years but the A50 peaked my interest. Looks like the same scenario, GSM models can be unlocked and CDMA can not.

I've seen atleast one other report that the 505U on Sprint and Verizon has locked BL. I've been told in telegram this si the case to. I have tested the 7 day trick extensively and it doesn't work on A505U. Did you have to do something special to get the oem unlock in dev options?

New To The Game..
Hello Gents...
Just picked up an Xfinity Version of the A50.
I have no plans to unlock and root.. as I want the security of Knox for Samsung / Google Pay.
But.. has anyone looked into what Xfinity is doing with their software?

Sprint Samsung A50 BL Unlock NO GO!
Ok so I am now an employee of Sprint. The information I have gathered is as follows. When Sprint requested this device from Samsung in their lengthy list of requirements one of them was that the ability to unlock the bootloader be removed. The reasoning behind this was that they did not want the end users to wind up " Accidentally " bricking their devices. As per insurance guidelines any attempt to modify the devices hardware and or software voids your warranty and your insurance that you carry on the device. So basically what they are saying is hey Android / Samsung community because of several hundred unintelligent people ruining their own devices we are removing the option in general. I am currently pushing to see if we can work with Samsung to push a firmware update that will allow this feature to be accessible as the whole point of having an android device it the open platform and being able to do these things. I really wish more cell phone manufacturers were like HTC which allows you to unlock the boot loader on any of their devices and even provide you a tool to turn S-Off on their website. But we cannot all be great.... Anyway hope that clears it up for ya'll and I am fighting the good fight on your behalf. P.S. I have the Samsung A50 and I was really not happy when I found out I could not root it.

@RoyalAssassin - QQ - will unlocked Sprint A50 work or can it be activated on VZ?

If you're sprint a50 is unlocked it should work fine on vzw. You can call vzw and give them you're imei to check compatibly.

Here in 2021 looks like things didn't go well :'(
My old A505U is just off contract and the "OEM Unlock" switch is missing from the developer options menu. Additionally, none of the normal methods for getting it to appear have worked for me. (I have tried reflashing the stock firmware, the whole messing with the date&time and updating, factory reset + login + wait 2 to 14 days)
I have spent hours on the phone with both Samsung and my previous carrier, but with no results; none of their support people have the knowledge/are allowed to help with unlocking the bootloader.
I am getting very discouraged that this old phone of mine will ever run anything open :'(

Samsung Note 10 Plus SM-975X

Hello, this is my first post but sure it not the last!
I have been exposed of fraud! I bought Note 10 Plus on a website called Blocket in Sweden were you can buy everything. The guy told me that the phone was locked to 3 and that was no problem because i have that to. But when he came to me he had activated the phone so WiFi call was on (I didn't know that). I logged in to my google account and then I also connected to my WiFi. Then i tried a call and no problems so I paid the guy and got a receipt and took his ID. But as soon as I went out I couldn't call and did some research and the phone had only 0 as IMEI and in small letters on the back it says that it is a Demo unit and have a serial number and its name is SM-975X . So my question is if anyone have been able to get a phone like this to work? Everything is reported to the police but he had false ID and the phone number has been turned off! I payed 650$ so would be so happy if anyone has an solution of my problem :fingers-crossed :fingers-crossed:

Sadly, there is no solution, only a motherboard replacement would work

Hm, is it so bad! Do they remove the radio parts for everything else works like a charm even WiFi calls and wireless charging both on my phone and to other phones to!
Do you know if the they only remove/disable the radio part and let everything else work?

What I know, is that there is no way to make it work as a regular device, they are intended to be used by vendors, to discourage people from stealing them from showrooms, precisely the cellular part is totally disabled

the IMEI is generally a unique identifier used by networks and such to track devices (stolen or otherwise) without one a device wont work on a network and the only way for a device to get one is from the factory encoded into the hardware, so short of swapping out hardware for a different board that has an IMEI there is pretty much nothing you can do.
as if it was simple to change them people would be able to hide stolen hardware or their tracks when swapping SIM cards. also would get them around blacklisting and other features on the networks.
the IMEI is basically the same as a VIN number on a car, even if you could change it you would need a valid one to register the device on a network.
it's sad but unfortunately all you can use this as is a learning experience, in future only buy from reputable sources that offer some level of consumer protection and always check things like the IMEI as people even sell blacklisted phones as they will turn on and seem to work but will be blocked off the majority of networks.

Yes it was a wakening call, but I have sold and bought 40-50 different phones and other stuff on "Blocket" but this was the first time i was cheated. I had no idea of that you could make WiFi calls otherwise it wouldn't worked! He had receipt and everything so I had no thought that it was a demo phone! Before he came i was looking for a site were you could write the serial number and look if it was stolen but couldn't find any! Apple has one and have used that often and had one guy that tried to sell a iPhone that was stolen!
I talked to a independent repair shop and he was willing to buy it for 200$ so he could use it for parts, then my lost is only 450$ but it hurts anyway

yeah screen battery and a few other parts would still be viable, it's mainly the board with the phone modem on that would be unusable as little more than a demo/home unit.
WIFI calling will still work as it doesn't use any of the phone identifiers other than stuff like the MAC address of the phone WIFI chip that even a demo unit would need.
A quick google should give you IMEI checker sites and it's something you should always check, if you have bought as many phones as you say, you have been very lucky this is the first to have a problem as there is a massive black market for stolen devices that are black listed and such, that is why IMEI checker sites are fairly common as most networks do allow access to blacklist device lists as they don't want them being sold on. so really IMEI is probably the most important thing to check when buying a phone as there are multiple ways it could cause you problems.

How are Consumer Cellular Note 10 Carrier Locked? Help Needed

I have a Note 10 Plus N975U1 that was sold as a Consumer Cellular device through Target. The phone came with the N975U1 unlocked ROM installed on the phone and there is no carrier apps or Consumer Cellular identification anywhere. The only reason I know it's Consumer Cellular is because of a message that popped up for something, can't recall what now.
Anyway, the phone acts just like an unlocked model. Put in various sim cards and the phone reboots through the blue recovery screen to update carrier software for the sim you are using. APN settings are available and can be edited. Everything is just like an unlocked model.
Except, it connects to the network for a couple minutes or so and then stops working. It acts like the Verizon versions do before they are unlocked by Verizon. Except the Verizon versions give you a little pop up stating the phone can't be used on another network. This model has no message.
I am guessing that they are locked using the same mechanism that Verizon uses for locking their devices now except they just are not showing anything to let you know.
Is anybody aware of exactly how this is done and any third party who can unlock it? I have tried a couple different unlocked ROM s as well as an AT&T and Verizon just to see what happens. Same problem.
Thanks

Have a link from the target site to the phone you bought?
I have a feeling that the phone is not actually unlocked or it may not be as what it appears exactly. You can run the IMEI number using swappa and see if the phone is indeed an U1 variant or just the normal carrier N975U.
It maybe possible (not sure how exactly) that your using an international variant that was flashed and configured to look like a N975U1. For example the phone listed here is an international variant that is compatible with US LTE, but I have some serious doubts with how compatible it really is. From past experiences with a local store that sells unlocked Note 10+ units for Net10, I discovered they are not actually US models and are really international models. They were flashed and configured in a weird way (best I can describe it) that it would work for the most part, work with Net10, but it would not work with the other providers here locally. It would at first appear to work but then fail all together.. It wasn't until I started digging into the IMEI number and what it belonged too that I discovered the truth of what the model actually is, and I then promptly returned the phone to the store I bought it from.
If the phone is just network locked and a genuine N975U1 model it would just seem that you only have to use the phone with the service for a certain period of time before they will unlock it. Consumer Cellular would be the best place to go to get (and ask about getting) the phone unlocked.

I resell used phones and specifically phones from Consumer Cellular. All the previous Samsung models used to come unlocked, but about the time the S10 was released, all their Samsung phones came with this unusual lock. I've tried working with countless unlockers and no one has been able to remove it. Once it connects to the internet, it downloads some google update and the phone loses voice/data service. I've wondered how they do this too. A few other models I have that have the same lock are the A10e A20 J7 S10/+ S20/+ Note 10/+. Really really frustrating as I've been searching for a long time now. If anyone knows anything, please let me know. I have hundreds of these that need to be unlocked. Also to clarify, yes they are all the U1 factory unlocked models.

Edit: Apparently when a carrier locked device is flashed to U1 firmware BEFORE unlocking, there is no software prompt to unlock the device. It probably was a carrier locked N975U originally. Maybe on Consumer Cellular firmware, there would be a prompt to unlock it?

These are the guys but they only do commercial work. I am pretty sure they never fail unlock.

These are not the U versions. I've sold CC phones for years and they are and have always been U1 models. Not only does it say it in the software, but even on the back glass. They are locking these things with an update somehow.
I'll reach out to swiftunlocks, but I would put a big bet up that they can't unlock it either. I'm connected with some of the top unlockers in the world as this is my business and no one has any idea. If anyone is reading this and wants a phone to test, I'll even send you one if you think you can unlock it. It's worth a lot of money to me to find a solution. The worst part is that these phones are all paid off and eligible to unlock through the carrier, but since "I'm not the original owner" they won't help me.

Bough from local dealer

I bought s20 ultra from local cell phone dealer off the craigslist. The local dealer seems quite reputable however the guy said IMEI has been changed which got me bit concerned but proceeded to buy anyway. What are the reason for that? Quick search of the internet shows it could be stolen. But I dont see someone from respectable local phone dealer (at least based on their yelp google review) doing that since they are sittiing duck.
I contemplated either to resell back or keep using and for now using. It is wonderful in terms of speed comapred to junk I carried briefly (LG Q70).
However, there is just bit of an easy feeling about using it with IMEI chanegd.
For now, I am doing for e-mail, phone call and various apps but hesitant about using with fin-app (brokerage), bank, ebay apps that involves money.
Any ideas?
What are the chances of mine being compromised? I am setting a common sense here as just because I got from wireless authorized dealer does not mean it is bad and getting a brand new from authrozied dealer (verizon) not necessarly guarantee security.

You bought a potentially compromised phone with a changed IMEI. That means that it's definitely stolen or was owned by someone who didn't want to be traced before being soled as a burner phone.
That being said, IMEI is just device ID. Meaning: Your device is in no way compromised just because a different ID. Surely whoever has the tools and your IMEI can track all your records across the internet and track your current location as well.
But don't worry the tools necessary for such a thing can only be accessed by authorized personnel of respective telecommunication company (Like AT&T) and your local authorities.
Also banking apps have meticulous safety checks before allowing the usage of the app, so don't worry too much.
However that doesn't mean that your phone is secured, as remains the question of how did they change the IMEI of your phone?
There are multiple ways to change an IMEI number but they all include one common point: They all directly affect some component in the device whether it be software or hardware.
So there is the possibility that your current software/hardware is compromised.
My advice? Just get a new phone, or make your phone secure again.
You can start by doing SafetyNet check. If the result is ok then you can be safe. (However as I said before whoever has the methods can still track you)
Flashing the stock ROM of the device then locking the bootloader can help. Also rooting the device then manually checking the device software for issues. Or simply changing the IMEI of your device again. (Only try those methods if you know what you're doing)
It's enough by itself that google, social media platforms and the government can track all your records across the internet whenever they feel like it, I myself wouldn't feel safe with potentially sharing my data with another unsolicited person.
So to answer your question:
Privacy is the issue when you have a potentially compromised IMEI. Not security.
Security is the issue when you have a potentially compromised system.
Hope I answered your question.

You've bought a stolen phone.
Theres absolutely NO REASON to change the IMEI.... EVER. If it has been changed, it is because the original IMEI has been reported stolen, and changing it gets around the cell network blocking it. There is NO LEGAL REASON TO CHANGE AN IMEI
I hope you are not caught with it, its essentially stolen property.
