Samsung galaxy j3 prime sm-j327t1 - Samsung Galaxy J3 (2017) Questions & Answers

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?

Verified boot. Maybe a root that takes affect after boot. Like a temp boot, an on and off switch type root.

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.

How can I check it?
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.

That sounds promising

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

Samsung S7 Custom binary blocked by FRP Lock

I got S7 SM-G930L with a port Rom from S8 (https://forum.xda-developers.com/s7-edge/development/rom-s8-port-s7-s7-edge-ambasadii-t3619548). When I power on the phone I get a message: Custom binary blocked by FRP Lock.
I would like to get rid of the FRP Lock without losing my data.
I saw a video https://www.youtube.com/watch?v=VdAhu45UPsU According to the comments 40% lost their data and 60% didn't.
Could you please advise how to make sure that my data won't be lost?

reflash the stock fw using odin
Not sure
I was said that because I'm using a port of S8 on S7, after I'll reflash stock ROM the data might be lost due to differences of memory formats.
Is it true?

Firstly I have a question regarding the OEM unlock as I just came out of the FRP Lock. Do I turn on OEM unlock or does it have to be turned off? Last time I had this FRP Lock was a year ago though did it again(the mistake with the OEM unlock) as I had forgotten it(Lots of grey hair)
Just don't know if it has to be on or off?
Secondly I have managed to come out of it(so far , hopefully) without wiping data with this guide

To unlock your device by frp lock you must flash the stock firmware when you are in bootloader mode you see custom binary blocked by frp,if you try to flash a random firmware(always of your device) the operation may not be a good end and device say an error with this:
Knumber) Snumber) Bnumber)
When you go to download the stock firmware you must see the "code" Of the firmware with write the same S or B number

It stops someone stealing your phone, wiping it, installing new firmware and using it as if it was new. If you know the gmail and password you put on the phone to access the play store then you just need to re-enter it after the phone restarts. FRP will only kick in if you have flashed new firmware to the phone.
I have a new firmware flashed on the phone.
And I'm using a new gmail with is, not some one July bro used on it.
What am I to do now? I have developer settings OEM unlock toggled on already.

I'm not sure what you mean. If you have a Google account on the phone that you know the email and password to, then just reboot the phone. FRP lock will only activate if you flash new firmware to the phone without removing the Google account first.
Your device should only have 1 Google account registered on the device which let's you access Play store etc. If there is more than one, you need to delete the ones you don't know the email and password to.
Okay...
Oh, okay, now I am getting the rationale.
Albeit, when I flashed in the new custom firmware, it started give me the undo changes by restarting your phone notification, like it did the first time ever that I got the lock. I didn't click it, activated an app that discarded the notification rather.
Now it makes me doubt if I had really removed my mail before flashing the phone.
hey
i have got the same problem. when i deleted xposed installer, my device rebooted. every time i try to turn it on, it says in top left corner 'custom binary blocked by frp lock'. i tried 3 diff rom to flash, no succes. i tried to acces twrp (my device is rooted) but again no succes. can you guys help me?

Yeah you've messed it up by not signing out of account before unistalling xposed. When you say 3 different rom's do you mean stock or custom?
Even in this state you should be able to flash a stock rom to the device with Odin and it will ask you to type the google email and password after boot.
Always turn off FRP lock before modifying the phone, it's a really annoying feature.

Is rooting this device possible?

On second thought, the FRP lock shouldnt be a big deal, all you really need to do is unlock the bootloader to install TWRP and to do that, you have to leave the phone powered on and connected to the internet for 168 hours. then go into developer options and move the slider. from there, just install TWRP and Magisk. Only downgrade block youll run into is the inability to go backwards thru the bootloader revisions. EG, if your phone is on revision 6, youre stuck with that. For instance the firmware in this link is for the Romanian version (i have a strong love/affinity for that country) A530FXXS7CSJ7 which is the 7th bootloader revision as noted by the alphanumerics i bolded
Thanks. I used the SIM PIN trick to unlock the bootloader. Unfortunately the device is blacklisted through IMEI so I'm going to have to return it.

Question How to unlock bootloader?

I just received my Flip3 (SM-F711U1) and would like to unlock my bootloader. However developer options is missing the OEM Unlock option. It's completely missing not just grayed out. I read a few articles about needed to change the system date but none of those guides changed anything. Can someone help?
Also, I attempted to call *#*#7378423*#*# to double checked that it wasn't already unlocked and I got a popup saying "Unabled to process the request."
Thank you.

Have you tried through fastboot? (fastboot oem unlock)
Oh, got you. Sorry!
As far as I'm aware samsung devices don't support fastboot. I did attempt to connect it in case I was wrong but was not able to get fastboot to recognize the device.

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.

if you're in North America, Canada etc Qualcomm chips there do not support bootloader unlocking, at least the Samsung one's don't, not sure about other OEMs.

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,

To root a phone's Android unlocking its bootloader is NOT required.
You simply have to add SU binary to Android's filesystem and make this binary executable.
I want to oem unlock bootloader for trwp and roms but I can't find oem unlock in dev settings and tried the video above and a couple of other things I found
You need the Samsung flash tool and the version of android for the phone and su +twep+magisk is optional good luck

I seen someone mentioned to root w/o the OEM unlocking switch available, all that is needed is to flash the SU binary with Odin.. I haven't tried this yet but I am almost positive Odin for windows doesn't even read the Samsung devices without the bootloader being unlocked.
Anyone care to chime in here? i'd be very appreciative!
Mainly WTF is the OEM unlock switch not available on my device. I actually have 2 of the same devices and both are without the switch.
Also would flashing SU work and do the trick?

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

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.

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.

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)?

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.

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.
