Hi guys,
first of all, thank you all for your amazing work! Its great to have such nice guys working on android.
I saw a thead in the "rom" section but since im new in the forum i cant ask in the thread there :/
Do i need to unlock the bootloader in order to flash twrp for full root?
What about the OTA updates? I guess i cant updates after i unlocked the bootloader?
I read about the funkyhuwei method but it seems to be quite costly. One time or maybe even per month ok but 1 credit for 10$?? Wow..
Thanks guys!
Yes. You need unlock bootloader to do other things like flashing twrp.
And you can receive ota updates.

Hi, I unlocked my bootloader, but every time I boot I see these messages that my phone has been unlocked and can't be trusted. I understand this is normal, but is there any way to NOT see this warning?
Also, does this affect any encryption, AndroidPay, fingerprint phone lock, security setting,.... basically, what does that mean "phone cannot be trusted"?

It can't be removed without locking bootloader again.
Not until someone figures out how to flash TWRP without unlocking bootloader, OR flash official firmware but keep recovery untouched.
And it doesn't affect them (afaik anyway, it works great with Magisk and I don't think it hides unlocked bootloader).
Does anyone have any development on this device? It's newer and running a droid 7.0 nougat. Any root info or bootloader unlock info would be greatly appreciated
I too am looking, upgraded from the smj320a, gotta day love the phone just needs root do I can retire my older one.
Side note, I noticed oem unlock is missing. Haven't been able to find a reason or answer.
Yeah I seen that too. I was thinking about trying the custom recovery twrp for the galaxy emerge which has the same board and specs as the j3 prime except it's running marshmallow. If I flash it that might work but then it will trip the frp lock and the phone will be soft bricked. It's hopeless with a locked bootloader
Well, frp bypass is kind of my new found hobby. Have locked 10 devices and bypassed them all, one was a new found bypass on the lg tribute 5 running that 5.1.1. So if you frp I can help. Can we tag people in these like that crap spy social network site? Aka FB. Because I do know someone who could possibly help.
I too would also like to root this phone. T-Mobile variant.
How do we go about getting the sm-j327t1 it's own set of development threads?

I don't own this device, but according to what I can gather, it seems that FRP can be OEM unlocked, but the property is not set hence the property set to 0 for sys.oem_unlock_allowed.
For why it doesn't appear in dev settings I think is another issue. Can anyone confirm that this device does NOT have a manufactuerer locked bootloader.
Just to clarify:
OEM unlock = disable Googles FRP lock not unlock the bootloader.
If this device has a manufacturer locked bootloader then the likelyhood of root for this device is minimal.

Also while roaming through a shortcut creator I noticed frp is an option in many of the secret menu settings, what ever happened to temp root?

The easiest way would be to simply remove the signature from the stock recovery image and then see if it flashes with odin. If it does the bootloader isn't locked. If it fails then it's highly likely to be locked.

Yes I didn't set a screen lock as from what I've learned that's what activates frp, unfortunately my laptop has crashed (anyone good at bios pm me) but still no oem unlock and adb isn't working now, pc at work I've got android studios downloaded but I'll refrain from the lock until I can check, still don't know how to pull a signature from a stock image tho... But also in that article it States that oem unlock was enabled even tho there was no setting but they had unlocked boot loaders
Hello. I tried to unlock my bootloader on FRD-L19, Nougat 7.0, Emui 5.0 i got the unlockcode, but in adb i get alwas this:

Yes, your bootloader is locked.. try again via fastboot to unlock it.
You'll need the original key when you are trying it
the Command is something like "fastboot oem unlock *key*".
I know that. Have you seen my problem?? but, thank you anyway! I need to no why i get "wrong password" and what means "frp unlock".

I tried it again. It doesn't work fu****g huawei...
I have taken 4 picures when i tried it. Can you find an issue? I don't think that i have made something wrong...
Thank you
I've had the same problem and it turned out that the first bootloader code i used ( with DC unlocker) is different from the one i got on the Huawei website.
So what i did eventually was to pay for the DC unlocker again.
I also downgraded back to MM, because i did not manually relock the bootloader before updating to N, which apparently locks the bootloader in a different way.
So I suggest dowgrading to MM and unlocking there plus relocking it before updating again,
IF you are sure you have the right / original bootloader code you used before,
or
use a 3rd party tool like DC unlocker to get the code.
You might have to downgrade to MM as well with this method . Not sure
Edit: Fyi, never post your IMEI online

It should either be an exe somewhere or just a bat file.
This tool does the same thing as a command window in the sense of unlocking the bootloader.
As far as I know it won't help with your problem.
Frp ( Factory reset protection) requires you to sign with your google account if enabled or you can't use the phone. ( Theoretically that is, I'm i noob myself so no idea)
But it was "locked" ( same as in your pics that is ) for me as well anf I didn't have a problem with it.

Safety is the enemy of freedom!! -.- Sounds very complicated! (sorry for my bad english). So, i was on android 6.1 and unlocked and rooted it. Than had my problems with root again (maybe the wrong supersu file, or something) Then i have downloaded update.app from hihonor and installed it from the external sd card and everything is working fine on my phone. but i can not unlock it. maybe i have the wrong software for my location ore something like that?
FRP unlock means "You have to unlock"? if its unlocked there will be "FRP unlocked"? i am right?
Maybe i should try the whole procedure from beginning. rollback, update etc.. and then try to unlock. or should i contact huawei?
Thank you and a nice evening *cheers* ^^

For downgrade you need a rollback package..
What is your model number and build number??
I have an honor FRD-L09 with build FRD-L09C432B394
I understood that I nned to rollback to emui 4.1 (android MM), then unlock, but after this step I cannot receive ota's so how can I return back to Nougat stock? And you have a trusted download for the needed packages?
I just want to use Titanium Backup to restore all my stuff... and some modifications (pixel launcher, magisk with some modules, viper audio, ad block, something this simple), nothing usually complex!

For downgrade process you don't need to unlock bootloader..when you downgrade you will receive OTA updates..
To use TB you need root..which is required unlock bootloader..
Why you want to go back to MM BTW??

You can try directly unlock without ticking the oem unlock. By boot into download mode. The other thing is your device or carrier or country wont allow your flip 3 to be unlock. There last step you can try is clean flash via odin with your latest firmware.

They used to, so there was always a possibility it returned.
I recently read this article on XDA about unlocking the boot loader on the Fold 3 which results in Samsung disabling the camera (WTH?), Is this a thing on the Flip3 too?
My device is rooted. I have always been able to find the OEM unlock option under developer options without any constraints.
My camera is NOT affected. I can still use it without any issues.
I have an European device (SM-F711B).
Hope this helps some of you to track down whether this is a location or carrier based problem.
Hey Redhatter,

Hey I am trying to root my sm-a037w, fully updated.
I remember having OEM unlocked it using the developer option which is now gone completely.
I'm using Magisk to patch the AP file
Then use ODIN to flash it and it stops at vbmeta with a error.
I'm new to this and have googled alot but now I'm really stuck.
So it fails, corrupt phone, I reflash oem AP and it restarts.
I have adb and fastboot ready to go,
Thank you.

This is your problem, right here. If you closely read the Magisk installation instructions:
Unlocking the bootloader on modern Samsung devices have some caveats. The newly introduced VaultKeeper service will make the bootloader reject any unofficial partitions in some circumstances.
Allow bootloader unlocking in Developer options → OEM unlocking
Reboot to download mode: power off your device and press the download mode key combo for your device
Long press volume up to unlock the bootloader. This will wipe your data and automatically reboot.
Go through the initial setup. Skip through all the steps since data will be wiped again in later steps. Connect the device to Internet during the setup.
Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader.
Your bootloader now accepts unofficial images in download mode

If you can't see OEM Unlocking in Developer Options, and you see KG STATUS: PRENORMAL on the download mode screen, Vaultkeeper is still active and will reject custom images.

Yea I've been trying for the last 48 hours and I can't figure it out how to get it back.
I did have developer mode active and had seen and allowed oem unlocking, not sure when I disappeared, I think it was the latest update.
Don't know how to proceed.
Tried setting the date back , disabling system update and software update, still no OEM Unlocking.
I have read those instructions many times, I have no prior experience rooting or modding android :/
Should I reflash original firmware?
Where do I go from here?

Did you ever see the OEM Unlocking toggle after you unlocked the bootloader?
I assume you -did- unlock the bootloader, correct?
OEM Unlocking does not unlock the bootloader, it simply allows you to.
Reflashing the firmware might be a good idea. Keep in mind that Samsung is notorious for trying to disallow custom binaries on newer bootloaders. This is all speculation though, I'd need to see the error you got to have a better idea what the issue is.
flashing firmware is bad idea, this won't reset vaultkeeper. check RMM/KG state from download mode screen first. btw it's called odin mode (not fastboot mode)

Knox Guard has to be disabled by connecting to the Internet and checking for updates, and you have to be on stock firmware to do it.
Flashing the OEM firmware won't hurt anything, and is the only way to unlock KG.
Vaultkeeper is disabled by flashing the multidisabler in TWRP.

Hey thank you once again for your help.
To be clear this is how I recall the events .
1. I did enable OEM unlocking in developer options.
2. I updated the phone through the user interface.
3. OEM unlocking option dissapeared entirely after updating to android 12.
4. Downloaded XAC region firmware using SamFirm
5. Copied AP to my phone storage
6. Patched AP with Magisk, then transferred patched file to my PC.
7. Flashed BL, patched AP, CP and CSC(not home) using ODIN 3.14
ODIN said AUTH fail at Vbmeta on my PC and on the phone iirc.
8.Reflashed using stock AP to make the phone usable again.
At downloader screen I never saw hold volume up to unlock bootloader, only press up to continue. (after booting holding volume up+down+power)
Are KG and Vaultkeeper the same thing?
I guess my bootloader is locked and now OEM Unlocking option is gone.
This is the phone currently on latest firmware.
ODIN MODE reads:
FRP LOCK:ON
KG STATUS: CHECKING
MTK SECURE BOOT: ENABLE (0)
sec ctrl status (1)
SECURE DOWNLOAD: ENABLE
Baseband version A037WVLS 3 BVJ1 (bootloader version 3?)
Thanks for all the info, sorry for the messy post and not including all the info required.
I will provide you with the info you request, I do not know how to verify my KG status, it reads checking in ODIN MODE.
I am also not sure of how to identify the region firmware I need, the software version in my about phone says:
SAOMC_SM-A037W_OYV_BMC_12_0004
BMC/BMC/XAC/BMC
I have downloaded both XAC and BMC, both have worked for me.
Ohhh, it's a Mediatek device

At downloader screen I never saw hold volume up to unlock bootloader, only press up to continue. (after booting holding volume up+down+power)

The proper way to enter device unlock mode is thus:
Unplug any USB cables, power device off completely
Connect a USB cable to your PC, don't connect it to your phone yet
Hold both Volume buttons, do not press Power, and plug in the USB cable.
The screen should turn on with 3 options: Volume Up for download mode, long press Volume Up for device unlock mode, Volume Down for restart. Release both Volume buttons, then hold Volume Up.
Device should prompt you to confirm you want to unlock. If it prompts you to confirm you want to re-lock, stop! The bootloader is already unlocked.

Are KG and Vaultkeeper the same thing?

More or less...Vaultkeeper is the process that determines the Knox Guard status, which in turn is what actually allows custom binaries

This means that KG (Knox Guard)/Vaultkeeper hasn't yet verified your device is supposed to be unlocked.

Is there nothing on there that says OEM LOCK?

That's exactly how - it tells you in download/Odin mode.
Since it says CHECKING, there are two things we need to do:
Ensure the bootloader is indeed unlocked, using the steps I gave above
Once bootloader is confirmed to be unlocked, you need to boot into Android, connect to the Internet (use a WiFi network), go into Settings > System > System update and check for software updates. This also checks Vaultkeeper/KG.
After checking for software update, enable developer options (if not already enabled) and verify OEM Unlocking is present; it should be grayed out with the message "Bootloader is already unlocked".
The proper way to enter device unlock mode is thus:
Unplug any USB cables, power device off completely
Connect a USB cable to your PC, don't connect it to your phone yet
Hold both Volume buttons, do not press Power, and plug in the USB cable.
The screen should turn on with 3 options: Volume Up for download mode, long press Volume Up for device unlock mode, Volume Down for restart. Release both Volume buttons, then hold Volume Up.
Device should prompt you to confirm you want to unlock. If it prompts you to confirm you want to re-lock, stop! The bootloader is already unlocked.

I just tried this and there is no mention of unlock bootloader, same as before (volume up to continue) I click to continue and it reads;

your device is FRP locked. you have to unlock with google account first.
as you updated stock ROM and downgrade is impossible, I doubt you will ever get OEM unlocking back. updating stock ROM was bad idea.
BOUNTY; fix for persistent RMM state lock after 7 days
I've had a situation where RMM state has always been prenormal and OEM unlock been absent for months on Oreo. After updating to Pie, OEM unlock appeared immediately on first boot, but RMM state prenormal was still there and flashing twrp give me...

I am using the device normally and bought the phone new, using the google account i created for it , so i dont understand how this is possible.
Idk maybe FRP LOCK: ON disappears once you removed all bonded samsung and google accounts (maybe not caused by Google Factory Reset Protection but Samsung Reactivation Lock)?

I assume you -did- unlock the bootloader, correct?
OEM Unlocking does not unlock the bootloader, it simply allows you to.

No he didn't unfortunately. For bootloader unlocking and passing vaultkeeper one have to repeat that step twice, before and after unlocking/factory reset in odin/download mode.

Upgrading firmware shouldn't cause problems with OEM Unlocking or unlocking the bootloader. You've stated this a couple of times but have yet to provide any source for your claim.
FRP Lock is simply on because he has a Google account logged in, and has absolutely nothing to do with OEM Unlocking.
@Johnhek you have already connected your device to WiFi, yes? If not, you need to do so, then go to Settings > System > Software update to trigger a check. Once done, go back to Developer Options to see if OEM Unlocking is visible.
If the bootloader wasn't unlockable, the OEM Unlocking toggle would never be present. The toggle controls the state of sys.get_unlock_ability which tells the bootloader it can be unlocked. There are a couple of props that control whether OEM Unlocking is available, ro.oem_unlock_supported which is supposed to be baked into the ROM at build time, and ro.oem_unlock_allowed which determines whether the toggle is available.
I will admit I'm not very familiar with MediaTek Samsung devices, but I don't see why the process would be any different. Still, here is a guide on using MTKClient
Let's just see if we can get the OEM Unlocking toggle back and make KG happy.

I don't know for SM-A037W but I know about people selling their Samsung phones on Android 10 for buying same model on Android 9 for reason.

I did have developer mode active and had seen and allowed oem unlocking, not sure when it disappeared, I think it was the latest update.

There is no official information but there are rumors that from certain security patch Samsung removed OEM unlocking forcefully (USA/Canada devices).
It's also my experience with SM-T555 region DBT still not unlockable as of today.
I think it's common sense when it comes to rooting/unlocking that older android versions are easier to root.

For other brands it's not possible to flash anything when FRP Lock is on. Furthermore that state means device is actually FRP locked. Didn't know about Samsung FRP LOCK ON is only information about device is ready for FRP locking, sorry about that...
nevertheless FRP lock is contradictory to OEM unlock, both together is afaik not possible (except for Xiaomi).
btw flashing stock firmware won't unlock RMM/KG prenormal
we will know more about in 7 days...

You can also try disconnecting from the Internet (take out your SIM as well) and set the date back by at least a week. Or you can set it forward.

It shouldn't matter, honestly, although I generally prefer to do one thing at a time - unlock the bootloader, THEN update.
I have a feeling that the MediaTek aspect of things may be the issue here, although I have no way of knowing.

Hopefully it will be of some help to you. It's not beginner friendly - you have to install Python and compile it, but if you can get MTKclient working, you can see if it's what you need.

Reading it now, I think I can handle it, the instructions seem clear.
As for the date trick.
I tried it while connected to wifi, I dont even have a sim card in this phone lol.
Tried setting to last month, havent tried forward in time though, will try disconnected as well.
The mediatek thing seems promising, I think the sec ctrl status (1) in the download screen is MTK related...
I will let you know.
I have read in one of the linked threads that SIM card plays a role here. I recommend to enable mobile data for 7 days, although there is less hope.
from what I have learned from elliwigy one can't cheat samsung bootloader not even with mtkclient. there is however paid service for devices with DID token on download screen (afaik Qualcomm only). but try mtkclient first it's a good exercise and maybe you're lucky and it works.

I tried mtkcient but I kept getting unauthorized handshake when trying to connect phone :/
Followed instructions as per link but I encounter one error in the process:
Get latest UsbDk 64-Bit
Install normal MTK Serial Port driver (or use default Windows COM Port one, make sure no exclamation is seen)
Get usbdk installer (.msi) from here and install it
Test on device connect using "UsbDkController -n" if you see a device with 0x0E8D 0x0003
Works fine under Windows 10 and 11
I'm on windows 11 and when I put the command "UsbDkController -n" in terminal it doesn't recognize it.
I installed the usbdk drivers from git hub, a .msi fil, from the guide.
Another problem is I don't know how to set windows default COM Port one.
