Possible to relock bootloader after root?

Hi guys,
It might sound dumb but I was wondering if it was possible to relock the bootloader while keeping root.
In fact, I did not want to modify my Honor 8 that much too soon but I enjoy playing some games on my phone using a pad, I did not want to spend alot so I just went with a pad I already have, the DualShock 4. It works well except the button mapping in native Android games, that's why I have to root to use Sixaxis app to solve the issue.
So I may have to root my device soon but I don't plan any other modification to the system atm and I particularly hate the warning message when you boot (gosh, I hated it on my Moto G but it was easy to replace).
That leads me to the thread title: Is it possible to root and then get rid of the unlocking message (relock the bootloader or anything else would be okayish)?
I just want to get root access on the phone for my gamepad issue and eventually setup some typical things such as a real adblocking solution (DNS66 is not bad but hosts file is still the way to go imo) and maybe Xposed.
Is there a way to reduce the modification on the phone? (Thus the idea of relocking it, I was thinking that maybe, once relocked it won't show the message. But maybe relocking just wipe the phone again? (as unlocking it does))
Thank you guys

thats possible to relock bootloader .but if u used flash custom recovery and SuperSu.zip to root your phone , after rooted device , please reflash stock recovery vi fastboot and relock your bootloader

I don't think it's possible to relock the bootloader and keep your device rooted.

It was possible with the Nexus 5 and a few other phones to root it and then relock it. Obviously the only way to know if that's the case on this phone is to try it. But you just have to make sure that the stock recovery is there instead of twrp before relocking.
One brave soul needs to try it though. [emoji4]

Well, I'll wait until someone who has a rooted device give it a try.
That screen would really annoy me... I always thought it was dumb to put that kind of screen... Damn, no need to remind us that it is unlocked if WE DID IT OURSELVES.

Samsung galaxy j3 prime sm-j327t1

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?

At the same time it says it's not allowed check pictures

Also found this,

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.

English? I have Odin, then what

I found an article saying for oem unlock to factory reset and don't set up Google, no frp to stop oem unlock. I'm backing up apps now will update in a few hours

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

Put the phone in fastboot mode, then run `fastboot flashing unlock` from a PC. If it says unlocking not allowed, you're out of luck, it's a brick now. Never lock your phone without being 100% stock on both slots

No idea. I've never relocked unless I am completely stock and take at least one ota first to make sure, along with full factory resets before and after updating.
There are others here that claim they where able to unlock again and save their phones though so maybe it's possible.

I thought the locked/unlocked bootloader setting was "sticky" though. Is that true?

You should now lock the bootloader for security...

Maybe this question deserves its own thread, but
Why is an unlocked bootloader insecure?

Simple, it allows anyone with physical access to your phone the ability to flash basically anything on it. That said, Ive unlocked every device Ive owned immediately after getting it.

General re-locking bootloader problem

I tried for my first time to unlock my phone's bootloader and thought it was something really easy to customize the
phone firmware on the other hand was not what I thought and I don't know much about computer science or customizing a firmware;
and then without being able to install a root or any modification I decided to re-lock the bootloader (because i dont want it anymore) only that I did not succeed with various tutorials and I did not find any for the samsung galaxy a12. I just unlocked the bootloader from developer options settings and ran what the tutorial said on how to activate it without installing a root or customization of anything.
can someone please help me.

Well it shouldn't be hard really. How did you unlock it in the first place?

Wait, is it really so hard to lock the bootloader on Samsung devices? Makes me think twice about buying one now if I can't simply lock it with a command like fastboot oem lock.

It's not hard to relock as its not hard to unlock it.
If you've followed any unlocking bootloader tutorial, after enabling OEM unlock option, you have to enter downlod mode and long press the volume up to enter unlock mode and then procedd to actually unlocking it.
For relocking it, just go to the download mode again, then long press the volume up and you'll have the option to re-lock it.

Samsung phones have a download mode instead of a fastboot mode, so you can't use commands like fastboot oem unlock
