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"

my phone is on 1.53, s-off and unlocked. im trying to relock it, but its not responding to adb commands. i reboot into fastboot and it shows fastboot usb, but when i type in any commands it just gets stuck at waiting for device.
any ideas?
What command are you using?
ADB commands works in booted android.
Fastboot commands works in fastboot-USB mode.
To relock the bootloader, type "fastboot oem lock"

so im in fastboot usb mode. i typed in fastboot devices and its blank.
i do remeber typing adb reboot bootloader when the phone was booted and it rebooted into bootloader mode fine.
i pulled the rom.zip from ruu and renamed it pg86img.zip. did the update and its still saying unlocked??
debug mode is active. but adb devices doesnt want to detect the device. any ideas what's wrong?
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

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.

Hi guys,
In the past days i've been troubling my head with trying to unlock the bootloader on my lenovo tb-x103f, but cant seem to enter fastboot mode
I've been using this guide as reference, among other searches from all around, trying to work around this, but cant really seem to come to the bottom of this.
from cmd
adb recognizes my device
"adb reboot bootloader" tablet just boots into the startupscreen
"fastboot devices" somehow "confirms" that im in fastboot, even tho Im acctually not (right?)
"fastboot oem unlock-go" finishes, and says its successfull, but nothing happens (obviusly, since its not acctually in fastboot mode)
from there it just sits there, and nothing happens. have to reboot it myself, either via cmd or the button
why is it not entering fastboot mode? is there any fix for this?
This is getting really frustrating as I just wanna root the tablet and most likely install lineageOS, or some other custom ROM..
thanks in advance
If you can reboot it with a command than you are connected in fastboot mode. It sounds like you have unlocked you tablet. Enter fastboot mode through adb again and try "fastboot oem device-info"
