Did you use the tutorial to get your unlock code from Motorola? And it will void your warranty.

yes i used the tutorial, and the same thing keeps happening it flashes to black for a split second and then straight back to fastboot mode with a locked boot loader
Did you go to Developer options and enable "OEM unlocking" ?
To get Developer options menu to show, go to Settings, then About Phone. Keep tapping Build number.

it is getting flashed every time I unlock or lock the bootloader. Below are the steps I took to lock and unlock.
1) Enabling the developer options.
2) Enabling OEM unlocking and USB debugging.
3) Entered the fast boot mode and used "fastboot oem unlock" command to unlock the device after this command the phone gets unlocked but it erases(factory reset) all the data of the phone.
I was trying to install the magisk manager.

Looks like you haven't been on xda for the last month or two, or didn't do a little research before unlocking bootloader.
After May Security update, unlocking process factory resets the phone. You need to hold down volume down buton before executing oem lock command. Search on xda for proper instructions.

thank you
I will do some more research.
Theres no toggle when I get to the AP fastboot flash mode screen and the status code is a zero. The boot loader had to be available at some point before or it wouldn't have been able to be rooted and have 4.1.2 installed. How can I access the boo loader ?

If bootloader is unlocked, you see a unlocked bootloader warning every time the device is booted up.
It is possible that spash screen could have been replaced though.
The bootloader screen does say Locked or Unlocked
From powered off,
hold the volume down button,
press and release the power button,
release the volume button when you see the bootloader info.

also rooting does not require an Unlocked bootloader.
The fastboot screen says LOCKED with a status of "0"
I def don't have that boot loader screen you posted there. Am I dealing with an impossible to unlock boot loader syndrome?

How "lock" or "relock" my samsung SM-T510 bootloader?
im getting annoyed by the message when it boots
I would like to know how to do this as well after flashing stock firmware in Odin, the option to toggle off OEM unlocking is grayed out. Any help would be awesome!

You can't choose the OEM lock until you re-lock the bootloader. You do that the same way you unlocked it. But be warned, it does a factory reset also, which means you have to go through the whole setup proceedure again. BTW, it is unlocking the bootloader that causes the message, not the OEM lock. Also, do you know that you don't have to wait for that message to disappear on it own. If you tap the power button when it appears, it goes away without the delay.

The OEM lock is grayed out. I have factory reset everything. Through Odin and device. I just want the bootloader locked again and reversing this procedure does not work. Not worried about erasing the device I've already downloaded the 2 to 3 hour 2.3GB file I pushed through Odin

Did you actually read my post. OEM and bootloader locks are two entirely different things. When you first unlocked your tablet, there were two steps involved. FIRST, you had to enable developer mode and turn on OEM enable. THEN, you had to unlock the bootloader by holding the proper buttons when powering up. To relock, you have to do that in reverse. First relock the bootloader,using the same buttons you did to unlock, and then, and only then, you can disable OEM. And the second step is optional. You don't have to disable OEM to get rid of the message.
Edit: And "reversing the procedure" does work if you do it right. It is the ONLY way to relock the bootloader and I have done it. So I know it works.
reedit: OK, I just did it again on my T510. Turn the tablet off. Plug the cable into the PC but NOT the tablet. Hold both the vol up and down buttons and then plugin the cable from the PC. When the green screen appears, release the buttons and then press and hold the vol up till the next screen appears. IT WORKS!

No I do NOT mean download/fastboot mode. Go back and research how to UNLOCK the bootloader. IT DOES NOT USE FASTBOOT. You DO NOT use fastboot to unlock Samsung devices. And "factory reset" via Odin is meaningless. You don't use Odin to unlock the bootloader either. BTW, Samsung and most other reputable tablet makers, intentionally make it hard to unlock their devices because it is a serious security risk if you don't know what you are doing. Do you know what you are doing?

I actually do know what I am doing as a matter of fact. I rooted all of our devices in this household including friends and family. Some of them are in my signature. You don't have to be a dbag about someone asking for help. Yes, I read your posts too, even after all your edits. I got it finally so I guess thanks for all of your generous replies to point me in the right direction. Have a nice day!

I apologise for getting snappy but I was starting to get frustrated trying to point out that the OEM lock wasn't the problem and that the "buttons" did work.
Thanks Lewmur
Just wanted to pop on and say thanks lewmur, I was getting sick of not being able to update and singe I bought a Galaxy S9+ I cant root that, might as well keep them both stock and use "altered" apk install files. I was not sure if it was possible to relock the bootloader, now I know lol, so thanks.
I have a TAB S6 running Android 10. Bootloader is unlocked and OEM switch IS NOT grayed out. I went into DL mode and all I saw was the same thing as when I unlocked the TAB in the first place. Anything special I need to do to re-lock this baby.

...Like you said, your instructions do work! But i think folk are getting confused in your last sentence...
..."When the green screen appears, release the buttons and then press and hold the vol up till the next screen appears. IT WORKS!"
with the term " 'hold' the vol up" you use - instead of 'Long Press' the middle Volume button option on the screen!
This method by Long Pressing Volume Up button will get you to the three options screen which asks if you want to lock your Tab...

When I enter the blue screen before step 11, I just get a message saying "Downloading... do not turn off target" and it never goes away.
On my US model, I only get to step 5. Nothing after that. No OEM Unlock. Not sure who is blocking it; AT&T or Samsung or Qualcomm. So this might work in international models, but does not work on mine.

Good afternoon, can you help? And actually, what is the problem with a friend's child blocked Galaxy A51, tried to apply all the magic failed, since the developer mode is disabled and I can't turn on usb debugging, I've already tried everything to put a custom recovery and still in no way (to remove two files with blocking using Aroma fm) The path through Samsung unlock also disappears, since this beast went into flight mode after rebooting and does not turn anything on. I have already tried the very last option through attiny and otg password reseller, but it has already reached 4 minutes for one password and this method has also disappeared. I also sent it to ADB through the regular recovery, but the commands are very limited, and I didn't find anything useful either

Try to flashing stock firmware
I am stuck on Entering Fastboot...
bootloader not opening please help me solve the problem
Imma need a bit of assistance here. I have been trying to get into Download (DL) mode while pressing vol up + down and plugging in the cable. But it just starts charging.
I can get into DL mode through recovery but that goesn't give me an option to unlock bootloader. Of course, OEM unlock and USB debugging are turned on. I even flashed the latest firmware A205FXXSBCVI2.
I was trying to odin flash custom recovery image which doesn't complete and on DL screen it says, Custom image (boot) blocked by OEM lock. I have unlocked a lot of phones before but I guess I never had to unlock a Samsung bootloader!
Thanks in advance.
This should work:
The following steps WILL WIPE YOUR DEVICE
1. Enable Developer Options by pressing the “Build Number” option in the “Settings” app within the “About” menu
From within the Developer options menu, enable OEM unlock.
3. Power off the device, and boot it into download mode:
With the device powered off, hold Volume Up + Volume Down and connect USB cable to PC.
Now, hold down the “Volume Up” button until you see the “Unlock bootloader” screen.
Then press the “Volume Up” button once to unlock the bootloader.
7. Your device will reboot twice and erase your data, you may now unplug the USB cable from your device.
8. Run through Android Setup skipping everything you can.
9. Re-enable Development settings by clicking the “Build Number” option 7 times, in the “Settings” app within the
“About” menu, and verify that “OEM Unlock” is enabled and greyed out in the “Developer options” menu.
If you have any problems, let me know.

Nope. I don't have access to that phone for the time being. But I came accross a point that we need to plug in the audio cable on new Samsung phones to get that unlock option.
Haven't tried yet though.
