Hi, how can I initiate the diagnostic tests? According to this: https://www.xda-developers.com/how-to-access-hidden-diagnostic-tools-on-your-android-phone/
there is a system app called HwMMITest which can be activated within the bootloader menu.
But there is no such menu when I press Vol Down + Power. Also the command: fastboot oem enable-hw-factory through doesn't work for me.
Any ideas?

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 just can't get there...
pressing pow+vol down or up' just deosn't work for me...

vol up worked.
thanks
I have entered "adb reboot fastboot" but it only reboot to the system but not reboot to the bootloader.
I have already selected the option about OEM unlock in the developers settings page.
4 me too...
I got there by hitting enter and immidiately pressing the vol up
I got a question:
I guess the pc doesn't recognize my device... But it turns out 4 other pcs don't neither...
Every time i get to bootloader, entering the code 'fastboot oem unlock' in the command window, and all it does is waiting for the device....
What should i do? It drives me crazy

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!
I'm trying to unlock the bootloader in my LG k410g, i open the ADB screen and i run the commands to restart in fastboot mode, and when i run the command "fastboot oem unlock" it shows the confirmation screen asking to press the Vol + but when i press it does not work, i have been reading some threads and i just found one saying that some devices have the bug when opening the fastboot from ADB the vol + it's not working, but i tried one of the solutions i found that was to open fastboot connecting the usb cable while pressing vol -, but none of the volume keys work neither. is there any other way to unlock bootloader? or any other way to press vol + via adb(sounds crazy but, i don't know)?.

Ohh & Something to help....
Only for very old Samsung phones, especially I9082, and posted for someone who had asked for it.
Fastboot commands are:
Code:
fastboot erase system
Or
Code:
fastboot format system
Code:
fastboot erase boot
Or
Code:
fastboot format boot
Code:
fastboot erase cache
Or
Code:
fastboot format cache
Code:
fastboot erase userdata
This is what will erase user data
Or
Code:
fastboot format userdata
This is what formats userdata (for decryption)
Code:
fastboot erase recovery
First try this command and install the recovery again with this command:
Code:
fastboot flash recovery twrp.img
Or
Code:
fastboot format recovery
Try this and then install recovery again with this command:
Code:
fastboot flash recovery twrp.img
If stuck and unable to boot to recovery, use the following command:
Code:
fastboot boot recovery twrp.img
To flash a boot file:
Code:
fastboot flash boot bootimage.img
Copy the
Code:
boot.img
file from ROM zip and flash that
What do BL, AP, CP, CSC mean?
CSC (Consumer Software Customization): It is specific to geographical region and carriers. It contains the software packages specific to that region, carrier branding and APN setting.
PIT (Partition Information Table): You only need it if you screw up your partition table or if the firmware specifically requires it because of a change in the partition table layout.
BL (Bootloader): As its name implies, this option is used to flash the Bootloader of the device.
AP (Application Processor or PDA): Also known as Android Partition.
CP (Core Processor): We call it Modem.
Update
Updated the OP with March release updates.
Now the files are available on AFH as well as foogledrive.

Hi what is "EDL Modes" ? Also in Post #2 showing the fastboot commands. In which circumstances should these commands be used?

Actually fastboot commands are not valid for Samsung phones. I had posted it just aa a complete guide for all commands.
EDL is Emergency Download Mode, which is equivalent to Samsung's Download Mode.

Personally, the fastboot commands you posted were quite confusing to me (first time having a Samsung device). That gave me a false hope that the M30 could be rooted using Fastboot. The same way I do all the time on Pixel device.
As fastboot doesn't work on Samsung devices, maybe you should delete that post? This is not a critique, I just wonder about the purpose of the info which cannot be applied.

Fastboot mode? Samsung only, right? Only Download and Recovery modes are there. From recovery mode, reboot to Download/EDL. The colorful screen is your download mode.
