Hello, I just got my Note 4X SD 625 and 3GB of RAM (bought it from Ebay) and I want to root it. I've seen some tutorials and I first need to unlock the bootloader but I think it already is unlocked.
It came with global version and I updated it as as soon I turned it on I got an update notification.
It the developer options and in the "MI Unlock Status" it says "This device is unlocked". I got the International version which came with Playstore and G apps installed.
Is the bootloader already unlocked? What should I do next to root it?
Also I've noticed that it says it's a Note 4 (not a Note 4x) I knew that but in DevCheck app and in the Security built-in app it says it has 4000mAh and not 4100. Is there a way to see if it really is a 4X?
Thanks in advance.
The line between Note 4 and Note 4X is completely messed up. Just know that you have a SD625, therefore your device codename is mido.
The battery is usually advertised as min 4000/ typ 4100mah so you are fine there.
Type fastboot oem device-info into fastboot to check if you are really unlocked.
All note 4x are unlocked by the resellers

My RN3 currently has Global MIUI 9 Global 7.11.23 | Beta ROM installed.
Yeah working, but it's unofficial unlock.

Thank you, Sir. I have tried the official method for the past seven days, but it gets stuck on 99% Account not bound to this device. That's why I searched for other methods.
Also, I am never going to flash MIUI ROM on my device again. Could the unofficial method still be a problem?

As you have official permissions first try to perform these steps & try unlocking :
> Locate device using MI cloud (find device) https://i.mi.com/
> check if the mail , phone are linked to your MI account
> Enable OEM unlocking & bind MI account with your device in developer options
> Download this https://mega.nz/#F!iQVFTB5Z!elmzC8piy8PukrOxiXHDFw connect the device to pc turned on - go to developer options & revoke USB debugging authorizations - now enable USB debugging - open cmd from the folder which you've downloaded - type adb devices ( hit enter button) - if it displays daemon started on port xxxx - you'll get a pop up on mobile ... accept it - disable pattern lock, num lock, etc delete fingerprints - now try unlocking logging in with a mobile number if it fails then email id & finally with mi account number.
Also make sure to wait for a week to unlock officially.
If everything fails you can proceed to unlock unofficially & remove ****UI from your phone.

Okay, Sir. I'd just like to point out the fact that I noticed one thing mentioned on that thread. It is specifically for Kate (Redmi Note 3 Special Edition) while my device is a plain Redmi Note 3 Kenzo with 2GB Ram and Hexa Core SnapDragon.
I think this might be a problem since that .mbn file mentioned on that page belongs to a different variant.
Can you please point me to the correct thread? Or a method that uses .mbn file to unlock bootloader on my device?

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.

Ahhhh, you might want to edit that info you posted... it's very unwise to display your imei info as there are those that are unscrupulous and may try to flash that to a device that has been blacklisted. You'd find out it happened when you go to use your phone and it won't work anymore.
I've been trying to figure out a straightforward and direct answer to this question for MONTHS, and it seems there are 12 zillion sites offering all sorts of bs, but I can't find a real and not-super-scammy looking answer. As of June 9th, 2022, has an exploit or method been found to unlock bootloaders on US based snapdragon variants of recent samsung devices? In particular, I would like to know about the SMG991u (samsung galaxy s21) and the SMT227u (galaxy tab A7 lite). If it matters: the device is no longer connected to a cell network
