I'm looking at picking up a SM-G965F/DS (FACTORY UNLOCKED) for use on the USA T-mobile network. The one I'm looking at is reportedly Region free (no region lock) and SIM unlocked. . So a couple of questions:
1 - Should I be fairly safe in my ability to bootloader unlock and mod this version of the phone as described above?
2 - To get the OEM unlock will I use my t-mobile SIM for 7 days to make OEM unlock available or will the date hack work:
How to fix the missing OEM Unlock button on the Samsung Galaxy S9/S8/Note 8
3 - I'm familiar with unlocking and installing on older devices such as the OnePlus One, and Nexus series of devices. Is the process for the S9+ fairly bulletproof like those devices? I mean, they were all pretty forgiving to a little "Oops" here and there. No one needs $700 brick.
Received the phone today. Cannot get OEM Unlock to show even using the above mentioned method. Anyone have any luck to share on the this model #?
Did you ever figure out how to get the oem unlock fixed. I just bought a Claro s8+ sm-g955f and no matter what I try the oem unlock remains missing in my developer options
Hello,
can the bootloaders of Samsung devices be unlocked without internet? So offline unlocking and without online account.
My Xiaomi phone and Realme phone need an internet connection and an online account to unlock the bootloader. There is no local possibility.
How about Samsung devices, e.g. the current Samsung Galaxy Note 20, can you unlock the bootloader locally, i.e. without internet connection and online account?

u could prolly unlock it give ur model is unlockable.. but ull runvinto issues with kg status being prenormal until u connect to data so u wouldnt b able to flash anything.. theres also a chance itll need to cojnect to data in order for the oem toggle to appear.. so most likely yes , u will need data either way

What do you mean by that exactly?
I want to buy a current Samsung Galaxy Note 20 (Snapdragon model) and unlock the bootloader and flash custom ROM.
That means I want to have the general possibility to unlock or lock the bootloader whenever I want to and it must be local.
I do not want these 3 points.
1. Bootloader can only be unlocked with an online account.
2. Request an unlock code on the manufacturer's website. Requires an internet connection to the manufacturer's server and must provide an email address to get the unlock code and then the user can enter it into ADB (Android Debug Bridge) to unlock the bootloader.
3. Install an unlock app (.apk) from the manufacturer and the Android device will be unlocked by the unlock app, but needs an internet connection in the unlock app.
Note:
I have tested everything with current Android 10 devices.
At point 1 I know it on my Xiaomi device.
At point 2 I know it on my Sony, LG and Nokia devices.
At point 3 I know it on my Asus and Realme devices.
I'm looking for Android devices that have a local and direct possibility to unlock the bootloader without online account, without unlock code (online request), without internet connection.

Another question you say on Samsung devices there is a KG State, what is that exactly?
I searched the forum, but there was no such clear information. As I understand it, it seems that when this "KG state" is set to "prenormal" on Samsung devices, the user cannot flash custom ROM and unlock the bootloader for about 7 days (168 hours).
Is this true?
What exactly does this KG State solve, how can it be prevented? Does it only happen for Samsung with Snapdragon model or only for Exynos model?

you will need a data connection.. even if bl is unlocked after u unlock it will wipe device.. u then need to reboot and skip through setup wizard and connect to mobile data or else kg status will be "prenormal" and not let you flash anything custom..
kg state is different than the 7day period. kg is also called knox guard and no, theres no way around it, u have to connect to data for it to change. it is on all samsung devices exynos and snapdragon.
and thats if its unlockable.. not all snapdragon devices can b unlocked.
also this isnt a xiaomi or lg or nokia or asus or realme device.. samsung has its own extra security..
theres no easier way to explain it.. i suggest u read up on it and check existing samsung device forums to get more info
I have now tested more Android devices and finally found Android devices where I can locally unlock the bootloader and also flash locally custom ROM without data connection, unlock code, online account and KG State.
It is a Google Pixel 3 and a OnePlus 7T. It is important that it is not the T-Mobile version!
So no provider devices, because when I bought a OnePlus 7T T-Mobile version I could not unlock the bootloader. It needs a unlock code (online request), because of SIM-Lock. It is not possible to unlock the bootloader directly and locally, for example to flash the stock rom (without T-Mobile).
My recommendation to the users, if you are looking for Android devices that can unlock the bootloader locally (via ADB) and flash locally custom ROM. Then Google Pixel and OnePlus devices that can do this, but only the free provider version, very important!

huh? you talk about bl lock because of sim lock (sim lock has nothing to do with it, even agter getting sim unlocked they are still not bl unlockable) then unlock locally via adb (isnt it fastboot which is not adb?) then pixel and one plus (theres many many other devices that are bl unlockable besides these two) then but only free provider version (huh?)
I meant fastboot and not ADB. Sorry, I downloaded this here on XDA forum. I have simply considered ADB as a whole
https://forum.xda-developers.com/showthread.php?t=2588979
Yes generally do not buy a provider version for all Android devices. There are only additional restrictions and is always dependent on the provider server.
I have to do this here with my OnePlus T-Mobile version, see the OnePlus support page.
https://support.oneplus.com/app/ans...-to-unlock-bootloader-for-oneplus-smart-phone
I need to unlock the SIM and request an OEM code and then I can unlock the bootloader locally and flash locally custom ROM or stock rom (without T-Mobile).
I can confirm that these Android devices Google Pixel and OnePlus without provider version can by default unlock the bootloader locally and flash custom ROM locally.
The user can just buy these Android devices in the store and do everything locally right away. No data connection is required. All you need are the tools and the custom ROM on the computer, which you can download and save to an external hard drive.
Quite simply said. Something similar when the user installs a Linux distribution (Ubuntu, Linux Mint, Fedora) on his computer or notebook.
Other Android devices, like I said before, need a data connection to unlock the bootloader, e.g. via app, online account or an unlock code (online request).
https://forum.xda-developers.com/showpost.php?p=83480827&postcount=3
Samsung devices I haven't tested, but have the similar problem (needs data connection to flash custom ROM), which you wrote yourself, because of KG State.
This is important to say, thanks. True as it is, only Google and Oneplus devices are free to use (equals root). Google can even accommodate GrapheneOS.
from my poor understanding of the recent 2-3 generations:
Root and developer friendly: google, oneplus
+ GrapheneOS compatible : google
+ Ez single command unlock like when we were young : oneplus
+ OTA Updates when rooted : oneplus
+ flash update without PC : oneplus
+ Encryption never touched : oneplus
Relatively root friendly : xiaomi, asus, sony, lg
+ official "support" of unlocking : all
+ without internet spying aspect of the procedure : none?
+ "featuring" disgusting wait period : xiaomi (realme)
+ chance of losing encryption: high (it is possible to forget ROMs and TWRP and keep it on some models)
Root unfriendly : samsung
+ official "support" of unlocking : no
+ "featuring" knox trip : yes
+ "featuring" key combination to boot : most models
+ can't even unlock : note20?
Root almost impossible : huawei, oppo and other small brands
now i don't care how difficult the first root procedure is or to knock some stupid fuse, but rather care more about how update procedure is, and can't adher to the new "standard" of killing encryption by disablers, so naturally i'm stuck to oneplus for the daily driver device. i can only look at the pictures and reviews of other brands
*people who root will go to heaven*
huh?
lol i dont understand most of last two posts.. i have g988u g986u rooted on unlocked bl no problem, no buttons need to be pressed, twrp exists, custom roms are easy, dunno what grahpOS even is and the list goes on.. if u kno wat ur doing samsung isnt that bad but yes, google 0urchased devices of course are easy

I have read all the answers here and would like to add additional points that the OP (original poster) mentioned but did not add to a concise list.
+ Unlock bootloader without network connection and online account : Google, OnePlus
+ Rooting and flashing without network connection and online account : Google, OnePlus
Note: The 2 new points work immediately and only if it is not a provider device. If it is a provider device e.g. from T-Mobile it does not work, in this case (Google and OnePlus) you need for the first step (unlock bootloader) a code from the provider and is dependent on its server so simply put, you need a network connection.

This point generally applies to almost all Android devices, regardless of whether the manufacturer allows bootloader unlocking or not (e.g. Huawei).
It is confirmed several times by users in recent years see in XDA forums. Some examples Sony, LG, Asus, Xiaomi, Samsung, Realme, vivo, OPPO and Nokia, no matter if provider or non provider device. These Android devices spy because the first step (unlock bootloader), necessarily requires a network connection. For example, via online account, code or app (network connection required, sometimes it works only if the user has mobile data in the app).
Simply put without internet spying is not possible.
If only compare this point with iOS/iPadOS devices, so jailbreak. Then it is almost similar, that is on current iOS/iPadOS devices you also need a network connection first to complete the "iOS Setup", when that is done a jailbreak (if available for the respective iOS/iPadOS version can be made). In some cases, so with very old iOS devices for example the first iPhone you can bypass the iOS setup (so without network connections) and can then, as usual make a jailbreak.

Pixels from Google and One Plus is what your looking for. In both cases you will have to fully boot the phone skip thru setup unlock developer option oem unlock toggle before you can unlock pixel or one plus
People this is a very big problem with Samsung and other manufacturers. Current smartphones are not independent devices, without server of the manufacturer nothing works.
LG is closing the bootloader unlock program that would help keep its Android phones alive
After ending its mobile business earlier this year, LG has confirmed it will also shut down the bootloader unlock program.
9to5google.com
Here is a very recent example. LG will soon close its key server for unlocking the bootloader. Until December 31, 2021, you still have time to unlock the bootloader of your LG smartphones. Later it is no longer possible.
so i bought this nord n10 from ebay and apparently when i got to the settings to try rooting it, the oem unlocking is greyed out. any solutions? i tried to find online but there wasnt really any so, i need to keep looking in these forums. someone said a solution about sim card unlocking or something
edit: shouldve mentioned this, its a t-mobile phone
also im very new to this
OnePlus Nord pure debloat follow guid it will enable oem unlocking. If it's a carrier locked phone you will have to get a oem unlock token via oneplus
if its a metro phone you wont be able to get a unlock token via oneplus they dont have the imei in there data base and are clueless how to do it
Fastboot oem get unlock data
Send the string of numbers to oneplus
Along with the IMEI number
after talking with oneplus they say they do not support MertoPCS N10 5G via unlock page and i have to ask MetroPCS for unlock token MetroPCS says its oneplus that has to supply the unlock token there has been a few user that are getting the same runaround one even filed a complaint with the FCC over it

Yes.
Clearly oneplus only added the imeis of t-mobile model number to the bootloader unlock data base.
For N200, metropcs version has the same model number so we can unlock the bootloader of metropcs n200.
The N10 can be flashed with the international rom via msm tool and the bootloader can be unlocked that way

You have no idea about what bootloader unlock actually is.
Your bootloader is still locked unless you get the unlock token from oneplus and flash it in fastboot.

My guy, I've been doing this since 2008.
My phone actually booted the dynamic system image and hit a DMverity wall. Previously, my phone wouldn't even attempt to install the DSU because because of the bootloader being locked.
bruh i tried looking up rooting beginner's guide and it was stilll complicated so is the other beginner's guide online, i really don't know what to do when im stuck, no tutorials on youtube to root the N10 5G...
I'm just about to return my Samsung A52 5G after realizing that the bootloader seemingly can't be unlocked. I did a quick google and thought it was possible, but apparently the North American version is locked.
Now I'm looking at this phone as my next option. Can anyone confirm if the OEM Unlock button appears in the Canadian version of this phone? I'm buying from the OnePlus website, and it says that it is carrier-unlocked (not T-Mobile).
I'm not even planning to root the device or do anything advanced, but I want to have the option to install Lineage later on once I stop receiving OTA updates, assuming that the Lineage devs make a build for this phone.

I believe there's a method to unlock the T-Mobile US version. I asked OnePlus's support, and there was a separate set of instructions for T-Mobile, so they might be able to help you.
I ended up buying the carrier-unlocked phone in Canada, and everything worked out; the OEM Unlock button wasn't blocked or anything. You just need the fastboot and adb drivers for the device, as usual.
There's a way to get oem ungreyed,read aroud
Even OEM and SIM unlock are separate, you have to have SIM unlock first before enabling OEM unlock.
Units sold directly from OnePlus.com is SIM unlocked.
Recently I bought used OnePlus Nord n200 from a website which is locked to T-Mobile carrier in about device option.
Though device carrier is locked but when I enable developer options bootloader unlock option is not greyed out also in engineer mode it shows device carrier is unlocked.When I insert sim into phone sim toolkit with sim card company name appears in apps but there are no sim signals is there any fix for this

Is your bootloader unlocked?
Yes I can turn it on from developer options
