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.

Hi all, yesterday I updated the bootloader of my OnePlus X and today I accidentally rebooted it into fastboot mode, when I tried to reboot the device it started a bootloop. Now I can't even boot into recovery but only in fastboot. I also tried to flash TWRP with command prompt but it says that the device isn't unlocked (strange i'm sure it was till yesterday) so I tried to unlock it with "fastboot oem unlock" but it says that oem unlock is disabled. Please help me
To unbrick your phone use this
You can then update to 3.1.3 Stock with the default bootloader.
You need to enable OEM-unlock in the developer-settings else patching the new bootloader may lock it again had the same problem.

Thank you! It worked
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.
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.
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
If you think that you have misunderstood some steps then feel free to reply
ok so i for the life of me cannot figure out what im doing wrong when attempting to unlock bootloader. I have my unlock_code.bin from oneplus, i have my usb debugging and OEM unlock enabled. I adb reboot bootloader, fastboot flash cust-unlock unlock_code.bin and everything seems to work fine. when i fastboot oem unlock though i get FAILED (remote:unknown command) what am i doing wrong? please help me.
I forgot to add my phones info
Nevermind yalll I figured it out. I switched to a linux box and used up to date adb and fastboot after fastboot flash cust-unlock unlock_code.bin the next command was fastboot flashing unlock NOT fastoott oem unlock.
I had a hell of a time figuring out how to unlock bootloader on this phone. Hope this helps someone else out there.
