Hello,
I have a unbranded 8227L running 8.1. In the past I have been able to successfully unlock the bootloader, but now I can't figure out how to get past the warning message. I check the box for oem unlock
in dev settings, then while temp root in place I reboot into bootloader. Then I run fastboot oem unlock, which presents me with the warning that my data will be wiped and to hit volume up to accept. For my life,
I can't remember how to get past this. I only have a volume knob, not a button to push.
Anyone have any ideas?

Does anyone know a way I can unlock the bootloader or unroot the phone without using the power button?
I can get into android recovery but cant select any of the options because I have no power button.
I managed to get into fastboot with the Toolkit and I was trying to get my phone back to stock to warranty it. I wasn't thinking and re-locked the bootloader before unrooting the phone. Now I can't "undo" that because of the phone prompts to choose yes or no when unlocking the bootloader.
I am looking for a way to unroot a phone with a locked bootloader or a way to unlock the bootloader while bypassing the yes/no screen.
I found a solution but it was for the galaxy nexus using a hex editor and I wasn't going to mess with that unless it was specifically for the nexus 4.
Any help is appreciated.
Is there any way to unlock the bootloader without the volume buttons? Mine have broken (even when the button circuit board has been replaced) and all programs or guides i have found ask you to do at least one action with the volume buttons.
Unfortunately i have also upgraded to 5.1.1 so no easy root options.
Stock rom (hence the need to unlock and add functionality due to the loss of hardware buttons)
Thanks!
I think you should be able to use abd and use a command that goes something like "adb reboot bootloader" which will allow you to get in to the bootloader and unlock it.
Sent from my Nexus 4 using XDA Free mobile app
You should also be able to reboot to Bootloader from NRT, can't you?
You'll be able to adb reboot bootloader but as far as I remember you'll have to confirm unlocking a bootloader using volume keys.
Just checked, if you have ADB debugging on, you can just use NRT to boot you into the bootloader from a regular state. No need to use button combos, however, I think you need to be able to use the volume rocker to confirm the unlock......
So, I accidentally pressed OEM unlocking to off. I have one question, do I have to unlock it again via fastboot or is it okay to just press the same button to "on" mode again. And yes I have unlocked it once via fastboot.
Left this here just to make sure.
Thanks for everyone!
You're fine, if the bootloader is already unlocked that toggle will do nothing, in fact many times after unlocking the bootloader the toggle will be grayed out since it serves no purpose once the bootloader is unlocked. The switch by itself will not lock or unlock the bootloader, it's just a security measure.
The default off setting prevents someone, for example someone who stole your phone who can't access the OS when you have a pin/password to be able to unlock the bootloader thus being able to wipe the phone and being able to claim it as their own.
it is getting flashed every time I unlock or lock the bootloader. Below are the steps I took to lock and unlock.
1) Enabling the developer options.
2) Enabling OEM unlocking and USB debugging.
3) Entered the fast boot mode and used "fastboot oem unlock" command to unlock the device after this command the phone gets unlocked but it erases(factory reset) all the data of the phone.
I was trying to install the magisk manager.

Looks like you haven't been on xda for the last month or two, or didn't do a little research before unlocking bootloader.
After May Security update, unlocking process factory resets the phone. You need to hold down volume down buton before executing oem lock command. Search on xda for proper instructions.

thank you
I will do some more research.
Note: I know, this is the XT forum, but there is no XT2 forum.
So, pretty much every single time I boot up the Huawei Ascend XT2, I get this error:
Your device has failed verification and may not work properly.

(1) Press Power key to continue.
(2) Press Volume Up key up to 3 seconds to enter erecovery to restore your device.
(3) Your device will stop start, if there is no operation.
----------------------------------------------------------------------------------------------------------
Now, I boot into fastboot & rescue mode, to see that my bootloader is unlocked, but my FRP is locked. I never unlocked the phone's bootloader, and whilst using this device a few months ago, the phone never gave this error.
If I press the power button, the phone works normally without any issues, but this message annoys me a lot.
Anybody know how to fix this?

lock the bootloader > but be warned it will wipe your phone and you will never be able to unlock it again because they quit unlocking bootloaders
the phone is actually worth more with the bootloader unlocked and the phone rooted
