Unlocking bootloader via ADB - Android Q&A, Help & Troubleshooting

Hey all,
So Ive tried to unlock my bootloader but its not working, ive followed the steps from this site to unlock it but its stuck on the unlock bootloader screen. I have two options to choose from yes or no I click yes but it doesnt work, yet I click no and it takes me back to choose from fastboot, recovery and normal. My phone is a Alcatel Pixi 4.
I have enabled developer mode enabled usb debugging. I also have confirmed the RSA fingerprint for the computer. Also I have enabled OEM unlock in dev settings. This is what my cmd prompt window loooks like. I will also take a photo of my alcatel frozen on bootloader screen.

C:\Users\Dan\AppData\Local\Android\android-sdk\platform-tools>adb reboot-bootloader
C:\Users\Dan\AppData\Local\Android\android-sdk\platform-tools>fastboot oem unlock
...
This is what my phone looks like that im stuck on.

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!

Can't define whether my bootloader is locked or unlocked. More info in thread!

So basically I bought the phone from Banggood, and everything is working fine, but I can't seem to be able to see if my phone has already it's bootloader unlocked or it is locked. I have read that xiaomi phones bought from these kinds of sites, have their bootloader unlocked because they flash a regional firmware. Anyways, the dialer codes didn't work, so I tried the adb method. I enter the command window from the adb directory i enter the following : fastboot devices . I see that it does indeed recognises my phone. So eventually I enter this: fastboot oem device-info and I get this error message(See attachment). I have disabled Drivers signing testing in windows. I have reinstalled the drivers. I have enabled USB Debugging and OEM unlock but no luck. What am I doing wrong? Ah, I forgot to mention that when I get into fastboot mode under the android icon it says PHONE Locked and that from an App in playstore that gives you the info of the phone on the bootloader status it said unknown. That's all I have folks. Help a brother out. Peace.
Well apparently through this site( http://www.hardreset.info/devices/honor/honor-9/faq/read-info-fastboot/ ), I found out that indeed my bootloader is locked and that I input a wrong adb command. So if there's something to be learnt from my short journey is never trust one site guys. Always look for other info as well.

Can't unlock Nokia bootloader

Hello there. I have a Nokia 6.1 with android 9.0 and i tried to root it. I enabled the developer mode, then enabled usb debugging.
But when i tried to unlock the bootloader, i couldn't because the OEM unlocking option stays greyed out on off. So when i installed adb and fastboot, i tried to boot by adb reboot bootloader but the fastboot can't do anything because it says device is locked.
I even factory reset the device, nothing. Same thing.
What should i do? Preferably not the paid unlock...
Thanks in advance.
Try this (It will wipe the phone, so create a backup of all important files before proceeding):
1. Connect your phone to your PC with an USB cable (make sure you have activated USB debugging in developer options)
2. Run adb
3. Type in adb reboot bootloader
4. Once your phone has rebooted type in fastboot flashing unlock or fastboot oem unlock
You should have unlocked your bootloader and you should be good to go, if it doesn't work then you'll need an unlock key, which unfortunately you'll have to pay for

I already found the solution, but it will erase your data.
with the adb commands you must restart the device in boorloader mode:
adb reboot bootloader
Then when I take you to the bootloader screen what you have to write next:
fastboot oem lock
(Remember the phone will be erased)
then to restart the device you have to:
fastboot reboot
And the device will reboot.
what you do is lock it, so that you can then unlock it in a simple way.
(If you do not know what the ADB is, warn man), I hope it helps you and those who enter here too :good:
@l3dson: Be careful before relocking the bootloader: The phone MUST be 100% stock or you will have a brick.
@Mohammedbi: Your bootloader is still unlocked, even after flashing the KDZ. It's just the newly flashed ROM doesn't know it, and you don't need it to.
Just go to fastboot (PowerOff, Vol- while plugging in cable) and flash TWRP. Follow ChazzMatt's root guide for the initial TWRP steps.
Have anyone found the solution for this problem...

What exactly is not working?
ADB doesn't require Enable OEM Unlock to be set. Just plug it in and ADB away - unless drivers or cable or port aren't working.
And your bootloader is still unlocked if it was unlocked before you flashed stock Oreo. You should be able to enter fastboot using the steps described in the post just before yours.
Edit: Of course you have to enable USB debugging in order to use ADB. I'm sure you knew that

Unlock Bootloader

Hi
I’m trying to unlock the bootloader of my H616 device but it’s not working.
I can reboot to bootloader and just see the green android alien but none of the fastboot commands work. I can see the device listed under fastboot devices but am struggling to unlock it.
Anyone have any ideas?
