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
Click to expand...
Click to collapse
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.

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.

Boot the stock recovery from fastboot.
Adb sideload OxygenOS
Boot into OxygenOS, enable developer settings and switch on "Allow OEM Unlocking"
Hi,
First I bricked my phone. Then I flashed the official stock rom using the SP Flash Tool. Then I started the phone and went directly to the build number and tapped it 7x. That made me a developer. Next I enabled USB developer options and enabled OEM bootloader unlocking. Then I connect my device to my Windows PC and start adb
Code:
adb reboot bootloader
That brings me into fastboot. There I use this command to unlock my bootloader:
Code:
fastboot oem unlock
After that I have tried two options:
Flashing twrp using
Code:
fastboot flash recovery x12-twrp.img
Which ends in a twrp bootloop. I guess because the cache was not wiped.
Using adb to reboot
Code:
fastboot reboot
. This however starts the rebootprocess and shows the Android man shortly - I guess that is wehere the cache is wiped - but then when I'm in the OS again everything is gone. It's like a factory reset. I can start over again by making myself a developer --> enable USB-developer options and allwo OEM bootlaoder unlock etc.
What am I doing wrong? I want to see the twrp screen on my phone. What should I do?
Many thanks for your help.
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>
