Hello,
I'm trying to unlock the bootloader on Cube1 M400. With "adb reboot bootloader" I can reboot the device to the fastboot mode. After "fastboot oem unlock" an Yes/No option appears on the device's display and It says to use Volume Up/Down buttons to choose but after pushing the buttons nothing happens, no option is highlighted. The device is sim-unlocked and not from the carrier. Thank you for help.
I have the Huawei Ascend Y300-0151 and am trying to unlock the bootloader, in which I cannot get through their website because it's really buggy and won't accept my information.
So these are the steps I've taken:
- Download SDK Manager and install platform-tools and Google USB Driver
- Boot my phone up and connect to the PC
- I can run the command 'adb devices' and my device shows with a unique ID.
- Boot my phone into recovery/download mode (purple screen).
- Connect my phone, the PC detects it.
- However, when I run the command 'fastboot devices', nothing shows up.
Yes, I have installed a driver for my device and it's now showing as Android Bootloader Interface.
I've run out of ideas and have been googling for answers for a very long time, but to no avail.
Any help would be greatly appreciated, thanks!

Given that your attempting to unlock the bootloader of your Huawei device, you should probably send an email to Huawei support requesting for your bootloader unlock code (thats what I did and they replied asking for my device information, and I gave it to them to which I then got my unlock code). For ADB to work you need to boot into fastboot mode, not recovery, then simply use the bootloader unlock code with the following command in cmd: fastboot oem unlock <insert your code here>
And then your done. Be cautious when unlocking your bootloader as you should make sure you have your developer options enabled and the "allow bootloader to be unlocked" option enabled as well.

I have e-mailed them 2 weeks ago and they are not replying. You're meant to do it through their website, but as I've said, I supply the correct information and it either re-directs to a page that is not there or says I am not entering my information correctly when I've done it over and over again.
The purple screen is fastboot mode isn't it? Because that's the screen I'm entering the commands in, but it's not showing up. I cannot enter in a code for fastboot oem unlock because my device will not be recognized by fastboot in the first place.
So before I am to unlock my bootloader, I'm trying to get my device recognized by fastboot.

You can send them an email to get the unlock code, trust me, thats what I did. Maybe try contacting them via their support section of their site if you didn't do so last time.
By the "purple screen" do you mean the screen with options such as "HBOOT", "Fastboot", "Reboot" etc.? The "fastboot devices" command should work if it is recognised by the command "adb devices"

I'll give it a go again, thanks.
By purple screen, I mean holding down the power button and both volume control buttons and the screen boots into a purple screen. Just a purple screen, that's it. I can boot into two other modes by holding down the power button and the volume up button and another by holding the power button and volume down button. I don't have a boot mode that displays any options as you've listed above.
EDIT: I'm in fastboot mode now! It was the mode where you hold down the power button and volume down button. Hahaha. I'll let you know how I get on with unlocking the bootloader. Thanks for your help
No problem, if you found my replies helpful please press the thanks button! It is much appreciated!
cmd with adb...
And I followed the steps meticulously - unlocked bootloader etc, but I get to the "writing recovery part" -
And it says FAILED (remote not allowed in locked state)
I don't get it! =(
I have unlocked bootloader, I have installed drivers, I did EVERYTHING...
Any advice?
In dev options it says my bootloader is unlocked however when I type:
fastboot oem unlock -
It comes up with options to unlock press vol up
but volume up button does not acknowledge me pressing it!!!
Please delete this thread no longer valid
thanks
I installed the android 10 update bit suddently when i rebooted it got on bootloop. I tried to go recovery and format it but it dodnt worked. Tried using mi flash but nothing happens. There is any way that i can unlock bootloader? (Cant boot and unlock oem)
Use the following codes on the adb after entering fastboot mode
First enter fastboot mode by pressing power and volume down until fastboot mode starts(about 10 sec)
Then enter the code
1) fastboot flashing unlock ( press enter)
2)fastboot --set-active=a (press enter)
Then run mi flash tool. Your phone should start.
Doesn´t work because the phone is locked and i can´t unlock it because don´t boot. That´s the problem.

Since your bootloader is locked and this loop occurred while officially updating you could claim the warranty and they will fix your phone for you.
Hi, I'm Apurba
I have an old Gionee P5L
I want to become a super user, so I want to root the device, but first I've to unlock it's bootloader.
I tried many ways, I used Bugjeager android application, ADB commend and many more windows tools.
In most case I followed the following commands…
fastboot devices
fastboot oem unlock
after that I got a confirmation on my Gionee P5L device about unlocking the bootloader, and I selected YES using the volume and power key.
after that I got this things…
Select boot mode:
VOLUME_UP to select. VOLUME_DOWN is OK
Recovery Mode
Fastboot Mode <
Normal Boot
but in here power & volume keys are not working, I can't move the arrow and can't select anything using
Anyone have any idea about this?
