Hi
Is it possiable to lock the bootloader after flashing android wear 5
or at least to remove the Bootloader Unlocked warning?
Thanks,
Dor
Yes. You can relock it.
1. Enable ADB Dubugging on the Watch
2. Type "adb reboot bootloader"
3. Once it boots to the bootloader, type "fastboot oem lock"
4. The device will restart and it should be locked

I have a little isssue with the bootloader...
Sometime ago, i have unlock the bootloader easily, no problems.
But now, i have checked if it is unlocked, and it is no longer
So i have tried to re-unlock it, and fastboot display that's okay and my phone reboot into recovery.
I have rebooted it into bootloader mode, typed "fastboot oem device-info" and nobody is true !
What do you think about this ?
Ps: Sorry for bad english
Okay, calm down.
Go to developer options and see if "OEM Unlocking" is enabled. If not, enable it.
Cool. Now enable USB Debugging, connect the phone to PC, open CMD and type
Code:
adb reboot bootloader
then
Code:
fastboot oem unlock
Download TWRP from the official website, rename it to recovery.img and then
Code:
fastboot flash recovery recovery.img
Now you have a recovery and an unlocked bootloader. Profit?
I hope this helps.
Thanks for your reply, but it doesn't work
I have only my old recovery (who is twrp in is latest version, no problems with that )
But suddenly i wondere if unlocked bootlooder is useful if i have already an recovery
Finally, i have followed the mega unbrick guide.
Pretty much what the title says. I'm on Android 7.1 (crDroid) with TWRP Alka installed and bootloader initially officially unlocked but now it shows that it's locked. Also, I tried unlocking with MiUnlock and it doesn't work. What do I do?
Just use MiFlash in Fastboot with Fastboot MIUI ROM. If you scared of EDL mode and/or it said your bootloader is locked then read below:
You can re-unlock it by using fastboot. You need adb, fastboot, xiaomi driver to do this. I recommend to use universal ADB & Fastboot.
Boot your phone to fastboot screen (aka bootloader mode) by using advanced reboot or adb terminal "reboot bootloader" or hardware key: Volume Down + Power
Code:
fastboot devices
fastboot oem device-info
If it show up with "Device unlocked: false" then unlock it by using:
Code:
fastboot oem unlock-go

If you setup MiCloud before going custom ROM, you will need to enter your MiAccount ID/E-mail and password.
Your phone will be locked again after using MiFlash, but you are at MIUI and you can use MiUnlock to unlock it anytime.
Does enabling OEM Unlock from developer options (Android 5.1.1) unlocks the bootloader?
If yes then can I directly flash a custom recovery after enabling OEM Unlock?

No, it only gives you permission to unlock bootloader.
You will need to unlock bootloader using adb.
Try this,
Download adb and Koush Universal adb driver and install them on ur pc, always install the driver first and don't install the drivers adb setup asks u to install.
Run command prompt as administrator.
Open the folder in c drive where adb is installed, u can use file explorer for this.
Press Shift+right click and select open command window here.
Enable USB debugging on your phone and connect it to the pc by a USB cord.
Enter command "adb devices" without quotation marks.
If it shows some device connected, only then proceed further.
Enter command " adb reboot bootloader"
Enter command " fastboot devices", if it shows some device to be connected, only then proceed further.
Enter command " fastboot oem unlock".
Ur phone may then ask for final confirmation on the phone screen, select yes.
When procedure completes, type "fastboot reboot" and your phone will reboot normally.

thnx for the reply augustonandro ! but i think im doing something wrong , whenever i type the command adb reboot bootloader my device(Galaxy J200G) restarts instead of rebooting to bootloader . So I just went to my stock recovery and chose option "reboot to bootloader" but still it restarted instead of rebooting to bootloader.
Am I doing something wrong?

guys i just found out this thread:https://forum.xda-developers.com/galaxy-j2/development/dev-samsung-galaxy-j2-lte-t3258147 and it says that just enable OEM Unlock and your bootloader will be unlocked. Is it true?
No, as explained above. That just allows the bootloader to be unlocked via ADB/fastboot (unless the bootloader is locked down like many ZTE phones).
Have you tried "adb reboot-bootloader"?

hi i have a galaxy note 2 n7100 and i have flashed twrp and rooted the device without messing with the bootloader at all,now i am thinking to flash a rom but i do not know my bootloader is unlocked or not,i have tried the adb fastboot oem device-info and didnt work because i couldnt get into fastboot/bootloader,i cant try the power and volume down combo bc my volume down key is stuck,any one can help
open cmd on your pc type "adb reboot bootloader"
then to check if bootloader unlocked type "fastboot getvar all"
then to exit from fastboot type "fastboot reboot"
So I have an unlocked XPERIA 1 III. I was trying to relock it (for software updates) and couldn't. I first tried going to the fastboot menu (adb reboot fastboot) and tried using fastboot oem lock. This resulted in a command not supported in default implementation error.
This is not a surprise as I had the same problem when I tried to unlock my phone. I then did adb reboot bootloader. When I unlocked my phone this was the solution to the problem however now when I reboot to bootloader, I get a black screen or I just boot into the OS. neither will accept fastboot commands.
Anyone have a clue whats happening.
If it is relevant.
I run Riru, LSposed, Magisk, Xposed Edge Pro... OFC I am rooted (considering I am using these apps... yeah)
Plz help
Try fastboot flashing lock 0x <your bootloader unlock code>
