LOCKING BOOT LOADER
You need ADB so follow these steps.
To lock your boot loader you definitely need to have a proper connection between your device and computer.
To re lock your boot loader you need to:
1. Turn off your device
2. Hold your volume down button and press the power button. (KEEP HOLDING YOUR VOLUME DOWN BUTTON) You will see a white screen with fastboot written on it.
3. Navigate with your volume up or down to fastboot and press the power button to select it.
4. Connect your device with your computer,
5. Open the terminal in your computer and type in 'adb devices',
6. Type in 'fastboot oem lock' without quotes and your device is locked again, you will see relocked.
but i don't know the status of my bootloader.. if i have bootloader unlocked, i can re-use the zip to back to stock, that it includes relock bootloader
and if i have bootloader locked, i will unlock it
how i can know if it is unlocked or locked? thanks!

You could try flashing a custom recovery to it. If it works, then your bootloader is unlocked.

Only try to flash a custom recovery. If it works, you have unlocked bootloader.
Remember that locking back your bootloader can brick your tablet, and that locked bootloader is not needed for the updates.
I unlocked twice my unlocked bootloader and notting happened, it said "it's already unlocked" or something similar, but do at your own risk.
i dont flash a recovery yet but.. i can enter to android system recovery <3e>
does this mean that i have bootloader unlocked?
thanks!
EDIT. i flash twp2 and it works.. so i hadn't have my bootloader locked..
sure, i'm gonna flash ICS.. no more JB now
I can't get the bootloader unlocked on a phone I just purchased with a relocked bootloader. I am on firmware 2.20 and my CID reads 11111111. I enter the unlock code and it says successful and I get the warning message on my phone about unlocking the bootloader and I hit yes to unlock. After the phone reboots all my data is wiped but when I reboot back into bootloader it still says relocked. I have tried multiple times with multiple unlock codes but no dice. I cannot get into stock recovery either after running the stock RUU. Anyone have any ideas? Thanks.

boot into the ROM and make sure USB debugging is enabled.. Reboot to fastboot and type "fastboot erase cache" and then try to unlock again

Bingo! That did the trick. Thank you very much. Man I do miss my old s-off phones.
Hi, I have the T-Mobile H830 Variant. I'm try to relock my bootloader because I have to take it back soon. I've already fully Unrooted my device but my bootloader is still unlock. I was wondering did anyone know of any way possible to relock the bootloader. It would be much appreciated if someone could point me in the right direction. Thanks in advance!
I'm wondering the samething. Might have to do it the same way you unlocked it. I used fastboot to unlock the bootloader. How did you unroot it.
Boot to fastboot mode then thru an adb shell, type the following: fastboot oem lock
Note this will erase your entire device.
Has anyone tried this to get bootloader unlock https://ge0n0sis.github.io/posts/20...-mode-using-an-undocumented-feature-of-aboot/
How do I unlock bootloader of a android device without enable oem unlocking option in settings?
I installed twrp in my device and accidentally locked the bootloader.
Now I am stuck in a bootloop. So I think if I unlock the bootloader and flash the stock recovery so my device will unbrick.
So how I unlock bootloader without enabling oem unlocking option in settings..?
