Good day !
I have come across a situation of unknown bootloader of SK17 .
I found some shop in Hong Kong is selling some cheap SK17 (not sure if it is the same as SK17i) . I asked the shop keeper and they said that the bootloader is locked , but without SIM lock .
So , will someone confirm me if this situation is possible ? As I read some post in this form it indicate that locked bootloader is usually because it is branded , i.e. SIM locked . If it is SIM free version does it mean I can make the bootloader unlock ?
And , what if the system shows "Bootloader unlockable ? No" ? Is there any way to work around this issue to make the bootloader unlock ?
Thanks so much !

Hi!
A simlock is something totally different to the bootloader´s lock.
No Simlock means that you can use any sim of any provider you like and who´s band is supported by phone´s hardware.
The bootloader ist locked by sony basically to prevent people from removing the sony Firmware even if it is not branded. A second issue is probably to prevent people from unlocking and playing with the firmware who do not know what they do.
Before the lock of the bootloader it was easy for everyone with one-click-tools or similar to root the phone. This could have led to many RMA procedures at Sony
But there must be a possibility to unlock it due to the terms of open source software.
So there is no need for you to unlock the bootloader as it takes any simcard anyway.
What the issue about sk17i sk17 and sk17a is, I do not know yet. But I´m curious about it
hi... how to know that your xperia mini pro unlock already in bootloader?
my rooting status is,
Bootloader unlock allowed: YES
is it already unlock in bootloader?? or not
It meens that it is be allowed to unlock your bootloader. It means not that your bootloader *is* unlocked.
Hi Poedel ,
Yes I understand SIM locked and Bootloader locked is different . But I wish to install 3rd party roms (CM7 rulez) , so I still wish to know how to unlock the bootloader .
So maybe I change a little bit about my question .
1) a sim unlocked device with locked bootloader (bootloader unlock allowed : no) cannot unlock due to the SIM lock . Then will it allow to unlock if the device change to SIM unlocked ?
2) Any method to work around the locked bootloader (bootloader unlock allowed : no)
3) Any way to unlock the bootloader if IMEI code cannot be used to extract the unlock code ? As I know some of the shop will use flash rom writer to wipe with another device firmware and IMEI will changes (it happens last time when I buy a X01HT) .
Thanks a lot !

this is still confusing The simlock does not take care at all if there is a bootloader-lock or not. I never ask someone if I am allowed, definetly not mr. simlock

okay, usually you'll go to the sony's dev site bootloaderunlockl.sonyericsson.com (don't know the correct sub, could be correct) and authenticated by your IMEI and email you'll get the unlock code. Without IMEI you won't be able to unlock. But even if you IMEI changed you can try the current IMEI. What I think is that Sony just saves the Email and IMEI into a mySQL Database to cope with the situation if your device enters RMA à la "you unlocked, your fault". It would be rather not the way that they look if your current IMEI really belongs to the device there. I would simply try it. BUT!
There is a post where a method is shown to root your ph0ne without unlocking the bootloader.
So here are both links:
rooting without unlocking not tested by me (even not yet read *covering*)
default way like I did it
Dear Poedel ,
Thanks , that's exactly what I wish to know .
So in worst case if bootloader is not going to unlock in normal way , I should use the test point function to bypass it and flash another room and firmware into it , and unlock the bootloader again ?
Thanks very much !

I bought ANE-LX1 (P20 Lite) on June 2018 and immediately unlocked the OEM from the developer options (automatic factory reset was done then), but i never rooted or installed custom rom, recovery...etc.
All updates was normally arriving and i was updating my phone regularly (current build is: ANE-LX1 8.0.0.170(C185)).
I decided to root my device using fastboot, but when the device is in recovery mode i can see:
Code:
Phone Locked -- (in green font color)
FRP Unlock -- (in red font color)
When i try to flash using fastboot i got:
Code:
FAILED (remote: Command not allowed)
While searching online i found that Huawei decided to lock bootloader for all users (so we buy their hardware which contains an opensource software and then they lock it... PERFECT!), and it seems that the only way now is to get the unlock code by contacting third-party codes providers, pay money and they guarantee to provide the correct unlock code (pay and pray) + I will have to expose my device information.
My questions are:
-How can i see in the developer options that my OEM is already unlocked, while the recovery is not convinced?
-Do i really have to unlock it again with the code "after purchasing it ofcourse -- which i will never do" (e.g. using fastboot)?
-Is there any solution from xda experts for my case rather than buying codes and exposing my device information or stay with a Locked bootloader?

Thanks in advance for your kind support.
and Thanks Huawei for putting us as a development community in this situation, where we have to pay for the black markets to unlock our own phones in an unofficial way.
Yes please, shoot some answers!

IMEI, product S/N (if i correctly understood the process, i have to provide my device info so they can extract the bootloader unlock key)
According to the information that's available, the code used to unlock the bootloader is unlocked in a very complicated way and it's basically unique for everyone. Now, I don't know how much this is true and how and why these people got their hands on the "method" of creating the code, but no one has been able to find a way that's guaranteed to work or even work at all, except for, of course, these sites that make you pay for it. I hope I'm not mistaken and forgive me if I am, but I don't think there is any way to obtain the bootloader code manually or without exposing your information to random strangers on the internet.

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.
I bought an unlocked S21 from Samsung directly; it currently has "1OYM2AUC8" firmware on it with XAA CSC. There is no "OEM unlock" option anywhere in the developer options, and my KG status says "Completed" in download mode.
I was gonna install Magisk and go for it—I'm computer-savvy, but haven't rooted a phone since 2014, lol. However, looking around I found several posts saying that there is no working root method for this phone in particular, unless I'm misunderstanding something horribly? Can someone set me straight here?

I've also been looking around for a solid root method for my device (G991U) and the only thing I've been able to find is a paid "token," which to my understanding is not a bootloader unlock and will not work on any post March security updated phone (i.e. my phone). I also am missing the OEM unlock option as well. With there being no guides and little to no activity on the forums I'm stuck on how to root this thing too. I've seen a couple of YouTube guides but they're for the exynos model (which also seems to have the OEM unlock option). Is there anyone working on an exploit or a way to unlock the phone bootloader? Is this token based from Samsung? It's been a while since I've rooted a Samsung phone and things look so different now. Could anyone she's some light on the subject for me and the guy I quoted? Tia!
Please let me know if you come back and find anything @pmacevad. I would really like to get this thing rooted.
US Samsung S series hasn't been bootloader unlockable since the S6 or S7, and root right now requires a $150 paid bootloader unlock. That's it. If you were looking for something easier, I suggest reassessing your need for root, or looking for another device.
After rooting my Z2 and backing up the TA partition, I've discovered that the bootloader is not unlockable (it's a Vodafone branded device).
Is there a nefarious way in which to bypass this? I understand that the whole point is to keep it locked, but it's an old enough device so I may have missed where it's possible.
Otherwise what are my options for an up-to-date custom rom? As indicated, I've already achieved root and have TWRP installed. I tried flashing Lineage via recovery but got an E: unknown command [log] error.
I'm in the same boat unfortunately. I bought a used phone that had Vodafone UK. It was marked as SIM-unlocked, and that seems to be true; the service info doesn't show any filled checkmarks nor counters in SIM lock information. However, bootloader seems to be locked forever - flashtool reports "Bootloader status : NOT_ROOTABLE" and phone's service menus also say that rooting status is "bootloader unlock allowed: no".
I wasn't even aware there are Sony phones that are not SIM-locked but are still boot-locked without any way to unlock.
I would really want to upgrade from Android 6 to at least 7 because there are some specific apps that work only from A7. Wondering if there is any custom ROM that would run on stock A6 kernel but with everything else from A7? It should be possible to install such a ROM even on a bootlocked device, right?
Since posting I've discovered some answers. The bad news is that, no, custom ROMs are limited without an unlocked bootloader.
The potentially good news is that you can pay for an aftermarket SIM unlock, which has the side effect of also allowing the bootloader to be unlocked.
I've not tried it myself, but do a search for "Sony cable unlock credits" for some leads.
Yea I also am stumbling upon this same news, in my city there are some shady areas so I will ask around and see if anyone is capable of doing it and will let you know.
So far my phone has bootloader locked, sim locked with 3 attempts left so I will work on unlocking those and then rooting the phone and digging deep after
Lets cross our fingers that somethings comes up
So far online , I find only old videos and outdated information, websites down and nothing else.
One thing is for sure, if your bootloader can be unlocked, you just go to sony official website and follow their instructions and its free and easy,
But if it says ""bootloader unlock allowed: no" then...lets see what can we do.
Hey I am willing to pay, why not if its going to unlock the bootloader 100%
