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.

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.
So,
I wanted to install a new recovery because i want to try out multirom (http://forum.xda-developers.com/oneplus-x/orig-development/mod-multirom-v32-t3316937).
But when i wanted to flash the recovery I found out that the bootloader is again locked.
I tried to unlock if again but the fist problem was, that it said "error: device offline" every time i did "adb reboot bootloader".
So i just bootet into fastboot myself and did "fastboot oem unlock". Then the program said that it finished and my phone launched TWRP.
I heard that you need to press "Yes" in your recovery but nothing showed up. The phone is still locked and i can`t figure out what to do/ what i do wrong.
I hope you guys can help me,
Andy
Hey there,
I wanted to install twrp on my google nexus 5x.
Therefore I've unlocked the bootloader, entered fastboot mode and flashed the new recovery file.
I did this with adb fastboot tool.
No errors occured during the process, but after restarting the bootloader and entering the recovery mode, twr opens for a few seconds
and then gets closed again. Now I get an errormessage everytime (device software can't be checked... please lock bootloader) and I'm unable to do anything in the twr menu because it keeps getting closed
over and over again.
Now I can't even start my phone "normally" and can't get a connection with adb (no results when using: adb devices )
Some Bootmenu informations:
FASTBOOT MODE
PRODUCT_NAME - bullhead
.
.
.
SECURE BOOT - enabled
DEVICE STATE - unlocked
Does anyone know how to fix this issue?
Have you tried relocking the bootloader?

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

hey i have this same problem and been asking around... but the adb reboot command will not work because it says the phone must be "enabled oem unlock" mode before you can use adb commands... which is greyed out..so back to square one... how to enable it?? any suggestions on this??
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>
