how to check if bootlader is locked - Huawei MediaPad M2

Hi Folks
I just got the Media Pad M2 8.0 and I want to check if the bootloader is locked or not
because there is no dialer installed I can't use the code I found in other forums
is there another way to find out?

Yes, there should be. You need to enter fastboot mode on the phone - i.e you need to get into the bootloader screen. The bootloader screen (usually called fastboot mode) will tell you if the bootloader and FRP are locked or unlocked - If it is locked, you should see "PHONE Locked" and "FRP Lock" in green, otherwise it should say "PHONE Unlocked" and "FRP Unlock" in red if the phone has been properly unlocked.
You can enter fastboot mode by either using ADB ("adb reboot bootloader", first make sure to enable developer options first as detailed in the Rooting guide, and then enabled USB debugging), or by first shutting down the phone and then powering it up while holding down the VOLDN (Volume Down) key. Of the two methods, I'd recommend the ADB method because the hardware keys method is usually hit-or-miss for me - sometimes it takes me to the bootloader, sometimes it boots normally into the ROM.
If you're on Windows and need the ADB and fastboot binaries, you can install the "15-second ADB installer" found in this thread.

Thanks, that worked, took me a while to figure everything out...
and it appears that my device is unlocked...

No fastboot option

Can't find anything on these forums or with google on this issue:
Unlocked HTC 10 purchased directly from HTC last week, received yesterday, running with AT&T SIM. Trying to unlock bootloader with HTCDEV but when I boot to bootloader or download mode there is no option for fastboot! Volume down + power brings me to download mode, my options are system info, show barcode, reboot to bootloader, reboot to download mode, reboot, power down. Tried reboot to bootloader. Phone reboots, says ***LOCKED***, ***S-ON*** and I have the options for reboot, reboot to bootloader, boot to download mode, boot recovery mode. I've ensured USB debug is ticked and OEM unlocked is allowed. I'm afraid I'm missing something obvious but I've used fastboot a fair bit on my m8 so I know what I'm looking for. I put a call in to HTC and their "special Bootloader Unlock team" is supposed to email me in the next 3 to 5 business days.
Tried a hard reset, didn't help.
All I could find on Google is some folks discussing an issue in earlier models of HTC phones - in those cases something about unticking fastboot in the "battery" menu of settings seemed to help but I can find no such options in the marshmallow variant on my phone. The HTCDEV site offers:
"If you have difficulty, power up normally, go to Settings->Battery and deselect Fast boot. Power down and try again." Must be referring to something from an older device because Settings --> Battery does not exist and Settings --> Power does not have a "Fast boot" option I can find to deselect.
Anyone have any thoughts?
Thanks...
It's has been renamed to "download mode" since M9 I think.
theres no fastboot option, it was changed to download mode on recent htc devices
once you're in phones in download mode & you have fastboot open on your pc
type "fastboot oem get_identifier_token"
the rest should be pretty easy
Htcdev explains all that on the first page of instructions as well.
Oops, got it...

Thanks guys, sure enough I was connected all along. I should have been able to figure that one out!
I'm not so sure Htcdev "explains all that" though. On the contrary, their instructions were the source of confusion! The first page says to "Use the Volume buttons to select up or down. Highlight Fastboot and press the Power button." Their note of clarification does not help, launching into a discussion of enabling OEM unlock. They ought to update that. Why on Earth would it be clear to me that connecting in 'download mode' instead of 'bootloader mode' voids their specific instruction to "select fastboot and press the power button"?
Anyhoo, all set with a freshly unlocked bootloader, thanks again.
Hello there...
Can you Please tell where the download option is available in HTC devices?

Some custom ROM's allow you to reboot to download mode via the power menu. If you're stock, power off the phone. Once it's off, hold volume down+power. Once the black HTC screen appears release both buttons. The phone will boot into download mode.

Touch Screen Not Responding

Update #2: I've been able to connect the A2 to my PC and can detect it when in fastboot mode with the "adb/fastboot" tools and with the MiFlash utility. I attempted to flash an earlier version of a ROM but I can't. MiFlash gives:
"Erase boot_a error"
I then attempted to unlock the device with the "Mi Unlock" tool but get "Sorry, your MI ID is not associated with a phone number"
Any suggestions on how to unlock the bootloader?
Update: After waiting a few minutes the touch screen started responding for a few inputs, and then stops. Toggling the lock screen a few times allows additional inputs for a few presses.
A couple of months ago the phone started displaying issues with touch input. Locking and unlocking the screen would correct the issue for a while. However, as time progressed the issue got worse.
Today I did a factory reset and since then I have been unable to input any operations. The phone is stuck on the "Hi there" welcome screen and I cannot press "Start". Power and volume buttons work fine, so I attempted to use "adb" to flash a new ROM, or a stock ROM from before July/August.
My PC won't detect the phone when in "fastboot"
What options are left?
Can I dump the stock ROM to an SD-Card and attempt to flash that from the bootloader?
Or do I need to unlock the phone prior to any ROM manipulation?
thanks for any advice

Boot your phone in system (normally).
Find build number in settings, about phone. Tap 7 times or until you've unlock developer options.
Turn on OEM Unlock and USB Debugging.
Turn off phone and boot fastboot mode.
Type 'fastboot oem unlock' and wait until it finish wipe phone.
And it's done.

Thanks, that worked. I am now able to flash an earlier ROM, will see if that fixes the screen input issue.
Flashed an earlier version of the ROM and still had issues, so I finally managed to flash an alternative ROM - HavocOS - and that experienced the issue as well. Looks like the phone has a hardware issue somewhere.

Question Download mode issue

Hi everyone. Ive got my first samsung smartphone. I followed guides to get root, but unfortunately I had no oem unlock button in settings, I used date tweak, and button appeared, until I closed settings window. However in download mode, I still dont have any option to unlock bootloader, only use vol+ to enter download mode, or vol- to reboot. I ve tried to unlock it from adb, but no luck I just get my phone restart while trying to acces fast boot with adb reboot bootloader. Please help, phone is cool, and I dont want to refund
If the oem unlock isn't in the settings app you can't root it.

Go to Download mode like this :
Turn off the phone
Hold volume + and - and then plug in a USB cable ( already connected to a PC )
Then you should see that "unlock bootloader" option

Question How to enter brom mode on Xiaomi Pad 5 (Nabu)?

Hi, I wanna flash a boot.img on my Mi Pad 5 with a locked bootloader.
I tried everything to get into brom mode, didn't work.
Please help.
First of all, you can't flash images with a locked bootloader. Second, this device has a Qualcomm processor, so there's no brom mode (which is found on MediaTek devices), you'll need to unlock the bootloader.

Bootloading Kyocera DuraXV Extreme

Hello, I'm having some serious trouble bootloading my Kyocera DuraXV Extreme (AOSP)
I've went into developer options and activated USB debugging and allowed OEM unlocking.
But I get stuck on rebooting into bootloader mode. I've tried different approaches:
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".
2. adb reboot bootloader command
Both options reboot the phone without going into bootloader mode.
Seems Kyocera decided to somehow lock the bootloader mode. Anyone know of a workaround here?

My comments below are based on the belief that you are trying to unlock the bootloader.
I am not familiar with this phone but generally the two steps mentioned by you are not enough to unlock the bootloader. After those steps, you'll have to issue a command via adb to unlock the bootloader and if successful, then you can boot into it for further operations. The command will vary between devices, so search and profit.
Thanks, this cleared it up a bit, you are right, I'm trying to unlock it.
I'm trying the command fastboot flashing unlock but only getting the message < waiting for any device >. I read somewhere that I might need some USB drivers but I don't know where to find them. I have the latest version of the standard USB drivers for the phone, but as I understand it I need special drivers for this?
I'm trying to follow the steps here: https://www.ifixit.com/Guide/How+to+unlock+the+bootloader+of+an+Android+Phone/152629#s317298
I get stuck on the step:
Enter the command adb reboot bootloader
Wait a couple seconds until your device rebooted into the bootloader, then enter the command fastboot flashing unlock
My phone isn't "rebooted into the bootloader", it just reboots. It gives the message "< waiting for any device >" when I write fastboot flashing unlock

It should be a driver issue. When the phone is on and you connect it to the PC/laptop and send the command 'adb devices', does it show an alphanumeric value? Likewise, when you are booted into the bootloader by key combination and send the command, 'fastboot devices', does it show the same alphanumeric response? If so, the drivers are installed properly. If not, either you don't have the correct drivers or they are not installed properly. Try installing the drivers again after disabling driver signing in Windows on your PC (search for it on Google).
Hello, can you clarify what you mean by "booted into the bootloader by key combination"?
My problem is I cannot boot into bootloader at all.
Any attempt at doing so results in a normal boot of the device.

Are you sure that the key combination for booting into bootloader is what you described in the first post?
1. Starting up phone while holding volume up and down buttons. Then select "reboot to bootloader".

I see Power plus Volume Up as the suggested one from a Google search. Try that.
If you can't even boot into the bootloader with the correct key combination, I don't know how to help you further since we are starting to go in circles. I am sorry.
Hello, thank you so much for trying to help me. It seems I can't boot into bootloader. Volume up + power gives the same result as what I did before.: It opens a "Recovery" menu where I can choose reboot to bootloader, but this option just reboots the phone.
I've been in contact with Kyocera and they say:
Thanks for contacting the Kyocera Customer Support. We will be more than happy to assist you with your concern
In this case allow us to inform you that since this device is a basic phone , it doesn't have the option to activate fastboot mode. By installing something that will change the way the phone works , that will void the warranty that came with the phone. We as manufacture can not help you to modify the software that came with the phone.
So the phone's fastboot mode has been deactivated. But since it's an android I guess it should still be possible with some workaround. I just don't know whee to start, I've been researching for a week with no result.
Something interesting ehre, maybe someone with more coding knowledge can tell what's going on.
I found the source code for the phone and located a file called recovery.c which I guess handles the menu I see when I press volume up + power button. Maybe some clue to why the phone isn't going into fastboot mode?
