OEM Unlock help - Android Q&A, Help & Troubleshooting

Hi, so I think I've bricked my Oneplus X!
Currently there is no OS on it but when I use fastboot it tells me the bootloader is locked and an unlock fails. It has the stock recovery bootloader which fails on format and wipe etc.
Is there any way to get it back working?!
Thanks in advance!

Locked bootloader - flash fast boot rooted ROM

I'm currently stuck waiting for xiaomi to properly add my device to their unlocking server, hopefully enabling me to unlock my bootloader. (I'm stuck at 50% during the unlock process)
My phone came with the factory installed China ROM. I then installed over this with the Global Stable fastboot ROM via EDL. Would it be possible to pre-root this fastboot image and flash via edl, enabling root with the bootloader still locked?
I am only wanting to root my device once unlocked, so thought this may be possible?
no dm verity in boot img in locked bootloader will refuse to boot your device.simply it will brick your device and end with a heavy paperweight and nothing

Huawei y6 can not boot help!!

If you do not have a bootloader unlocked, you will not be able to recover from the twrp recovery and unlock the bootloader again. Then you can install twrp recovery, install custom ROM, install gapps, reboot, and you can not boot?? please help!

Well.
Your phone doesn't boot anymore?
Does it boot to recovery?
You could factory reset maybe, if you can get to recovery, or maybe install an Update.app
Well if you have USB debugging, OEM unlock on, you can still unlock your bootloader
Go to www.imei24.com and write your phone Imei.
Now you can get some information that will help you get the bootloader unlock code.
After that go to: https://docs.google.com/forms/d/e/1FAIpQLSeGwoQ44zqykuTfjCQrVP07JOHBYnBcAxAbz9SAVxPTFqMh9g/viewform
And get your bootloader unlock code.
Now unlock your phone and flash twrp.
Make these steps only if you have USB debugging on and OEM unlock on, and if you can go into fastboot.
If I helped you, thanks button works well.

Relocking Bootloader

Hi guys,
I got a bootloader unlocked ANE-LX2J and I want to lock it again but I dont know the next step.
I still have the bootloader unlock code and already flashed FULL OTA using TWRP and did factory reset.
So now, my P20 Lite is running pure stock again and ready to be locked right? or still not lol :silly:
Based on what I read here, after relocking bootloader using fastboot oem relock command, the warning/alert that shows when the device is booting is still there and I want to get rid of it.
Thanks :highfive:

Yes, you're ok to relock your bootloader if all partition and recovery are stock and your device is working without issues. After relock the recovery will do Factory Data Reset and no more warnings "your device has been unlocked and can't be trusted"
Boot into Fastboot&Rescue Mode and use this command:
Code:
fastboot oem relock [I][B]yourcode[/B][/I]
Then you enter into Lock Bootloader menu and just follow the instructions.

NO -

Does the Lock Bootloader menu will automatically show after relock command? I'll give it a shot later. Thanks :highfive:

Yes, if your code is correct.
If my phone was rooted, will relocking the bootloader unroot it?

it will show a red text saying your system has been tampered with and turn off..
you will need to restore a completly stock rom with sdcard before you can boot the phone.

Hard Bricked Asus Padfone S

Hi,
I have a bricked Asus Padfone S with bootloader locked.
Is there anyway I can backup my data before unlocking the bootloader?
I understand that unlocking bootloader will wipe all the data.
Currently I can only access fastboot.
Recovery mode cannot be access.
I tried to flash the original recovery img, but the phone still failed to load to recovery mode.
Any idea where should I start?
Thanks

LG Phoenix 4 bootloader unlock on 8.1 Oreo

Please if anyone can help me with the AT&T LG Phoenix 4. I need to unlock the bootloader so I can install custom recovery. I have already tried to do it with ADB, but when I type reboot bootloader the phone just reboots all the way, and when I type fastboot ome unlock it says waiting on device I don't think there is a fastboot mode on 8.1. I just know everything I try to type to unlock the bootloader it just says waiting on device. If any one has any information on how to unlock bootloader and or install TWRP or a custom recovery please help or any info on rooting this device now that it's on 8.1 would also be great. Thank you in advance
Same issue here. Read that 8.1 relocks the bootloader. Need a solution for this. Download mode is available on my device which permits firmware update. Anyone know where to put an image?
