-Go to Settings then to About phone and find your build number.
-Tap on your build number 6 times until you see “You’re now a developer”.
-Go in Developer options > enable OEM unlocking.
-Connect the device to your PC.
-Power off your device with POWER and volume DOWN and directly hold volume UP and DOWN together!
-Device will boot in DOWNLOAD MODE.
-Long press VOLUME up to unlock the bootloader. This will wipe your data and automatically reboot your device!
-Go through the setup and enable Developer options again.
If you see that the OEM unlocking option is greyed out, you unlocked your bootloader.

Hello,
I'm trying to unlock the bootloader on Cube1 M400. With "adb reboot bootloader" I can reboot the device to the fastboot mode. After "fastboot oem unlock" an Yes/No option appears on the device's display and It says to use Volume Up/Down buttons to choose but after pushing the buttons nothing happens, no option is highlighted. The device is sim-unlocked and not from the carrier. Thank you for help.

To enable OEM, you must first reveal the hidden developer options tab (i'm not so sure) but go to Settings>About Device then find the build number. Tap it 7 times or more then it should say "You are now a developer". After that, exit from about device and you can see the Developer options. Tap it and find OEM unlock. Enable it.
To flash twrp recovery via odin, simply download the twrp for your device. Search google for "twrp for j100h". Download latest version of Odin, install it then run it as administrator. Click Phone then find the .tar file of twrp. Flash it then wait for it to say PASS!! in a green background. You now flashed twrp to your Samsung Phone.
Hope it helps!

OEM unlock option not available on all phones in developer setting. Boot your android in fastboot. Type "fastboot devices" enter and type "fastboot oem unlock" and enter. It will unlock your android bootloader and flash your recovery.

To enter into Fastboot mode, do this:
Turn off your phone.
Hold down Volume Down + Power button.
Release the Power button when device starts and continue to hold the Volume Down key until you enter into the bootloader. ...
Scroll up or down with Volume keys and select Fastboot with the power key.

I can verify this: My J100H does not have a.) an OEM option in the developer settings and b.) does not boot into fastboot.
I can boot into download mode using volume down + home + power. But "fastbood devices" on the connected computer does not show the device.

Thank you for your reply.
Yes and no, it is as @adarshadhungel1 says in https://forum.xda-developers.com/showpost.php?p=70830154&postcount=3,
there is no Option to unlock OEM in the Samsung 4.4.4 stock rom for the SM-J100H - so it seems. Could not find it anywhere.
Also, there seems to be no fastboot mode, as @TheExploitedOne mentions here: https://forum.xda-developers.com/showpost.php?p=83120343&postcount=3
So, I am stuck using Odin on Windows. At least for the first download it worked for me, now that I have TWRP on the phone, it seems I can handle the rest from linux...

Yes Samsung devices implement the Odin protocol rather than fastboot mode. There is maybe one or two devices that are Samsung that have fastboot instead of Odin by are probably rare to find

Hi...
You apparently have enabled developer options and usb debugging. Did you also enable OEM unlocking from the same menu?

On your device, go to Settings -----> About phone. Tap 7 times on the “build number“. You should now have enabled developer mode. Go back to the Settings menu and enter "Developer options" and enable USB debugging. Also check “OEM unlocking“. (It might be that you firstly have to connect the phone to a PC and tick “always allow this computer”and then get back to developer options menu and check “OEM unlocking“.
You may then start working with adb and fastboot.
(ps. Be aware that unlocking the bootloader triggers automatic factory reset - you will lose what you have not backed up)

Ok... Step by step... Please make sure you type exactly the commands as shown here:
1. type adb devices if it works, and shows your device then:
2. type adb reboot bootloader. If it works, and you should boot to bootloader. Next:
3. type: fastboot devices. Is you device stiil listed??? If not then there is some kind of trouble here. Your device is listed by adb, but not fastboot. If that is the case I personally do not have experience to help out. The only thing I can think of is that you may have missing drivers that do not allow correct communication between you device and PC.
If that is not the case and your device is listed by fastboot, then:
4. type: fastboot oem unlock. It will show that it is waiting. You will have to look at your device's screen and by using the devices buttons CONFIRM oem ulocking (on your device, not the windows command prompt)
5. If all goes well, your device should ask ask to reboot. Either reboot from menu, or just hold down the power button for a while.
6. After reboot, if all went well, your device will restart and perform an automatic factory reset. You cannot do anything about it. It just happens with OEM unlocking. At this point let it boot normally, and re-enable developer options and usb debugging to continue with root process, or anything that you want to do.
Can't thing of anything else for the moment... Let us know how it goes, perhaps a more experienced member, could share some insights???
I have already enabled usb debugging and oem unlocking yet neither adb reboot bootloader nor using the volume down + power button boot into bootloader mode, both of them lead to the tablet restarting normally to system

The problem is at Step 2 adb reboot bootloader only reboot device not booting it into bootloader.
anyone else getting this problem?
Let's wake this thread in a bang! ?
Come on guys! Did anyone manage to deal with the problem? I have absolutely the same issue. Step 2 is the problem for me too. No fastboot mode neither through adb reboot bootloader nor the tablet physical buttons. I get either a normal reboot or the stock recovery which has not many options.
Any help would be appreciated!
Thanks in advance!

That's not a proper unlock bootloader..it is safe unlock bootloader using unlock tools from xiaomi. If you unlock the bootloader to CMD it's a chance to brick. I think the proper to unlock is xiaomi tools

You must unlock bootloader first
Does uypur phone show the authorization popup when you connect for adb and have you allowed always allow this device?
What are you all talking about in this thread?
There is NO WAY to initially unlock the bootloader without MI account, phoning home and waiting 167+hours.
PERIOD. let that sink in.

Whatever you want to do after that, requires this step before. There is no "root without MI account".
