Bought this device and everything works great and I have root. When I try to unlock the boot loader by going to "Developer Options" and checking the "Oem Unlock", I then
Code:
adb reboot-bootloader
At this point I do a
Code:
fastboot oem unlock
Which then the device asks me to use the volume buttons to confirm, Volume up for yes and volume down for no. The problem I'm running into is in fastboot mode it seems my volume up and power key are completely ignored. They work in recovery and in android but not in the boot loader itself.
I have tried unplugging the phone after sending the command over to see if that is a factor but it doesn't seem so. I'm only allowed to use volume down which denies unlocking the boot loader.
Another thing if anybody can get me a scatter file that would be much appreciated.

How did you root the phone?
Hoping for an answer to the bootloader question as well. For root I'm going to attempt kingoroot and replace with supersu

I went through the process of rooting and then unlocking the bootloader based on this thread:
http://forum.xda-developers.com/showthread.php?t=1709424
And everything seems to be fine, I even installed CWM Recovery, but I can't load the bootloader to recovery mode or anything. I've turned off fast boot and am applying the power button + volume down key for at least a minute. Any ideas? Thanks for your help!
Try plugging your phone into your computer and adb into the bootloader using the command adb reboot bootloader. I have a hard time with the buttons but this always gets me into it.
After messing around with my shield last night and not being able to get root access on cm12. I tried to reinstall one of the ota updates from a while back. Now I am bootlooping and when I try to boot into CWM it looks to be corrupted and doesn't load. I cant use ADB because usb debugging is no longer active. Does anybody have any suggestions to re-install recovery or somehow enable debugging or am I dead in the water here? Any help would be greatly appreciated
Is your bootloader unlocked?
Can you get into fastboot mode?
HW method:
Turn off the device
Press and hold "Back"+"Home"+"SHIELD" buttons till device boots

If you can get into fastboot mode and your bootloader is unlocked, you can use a command like "fastboot boot recovery.img" to have the device boot a recovery.img from your computer without flashing anything.
If you can get into fastboot mode, but your bootloader isn't unlocked you could try unlocking your bootloader, but this will wipe your data - so only try this if you don't have anything important saved. The command is "fastboot oem unlock".

The bootloader is unlocked Whenever I try fastboot mode the device is not recognized because USB debugging is disabled .
Update: Fixed
I have unlocked my Huawei tablet using
Code:
oem shell
-> reboot fastboot
and later in fastboot mode:
Code:
fastboot oem unlock <pw>
now each time I am trying to enter the fastboot mode I get the
nasty "Your device has been unlocked and can't be trusted"
and throw me back to the regular boot.
Any idea what else I can try?
Code:
The info of my model is:
Named: Huawei M3 Youth

Thanks for the reply but nop in HuaWei the gicky stuff comes with volume up button but in that case the
same thing I get the ugly text message and normal boot :/
Any other ideas?
Found it: you really hold the volume down and just plug the USB cable no other
actions required, it will turn on into the fastboot mode.
i have a insignia with same problem get nasty mess. bootloader error code 3 but can not get to boot to fastboot mode only factory recovery . in factory recovery mode i select reboot to bootloader and if just restarts again with same bootloader mess. error code 3
Hello, I have problem with my softbricked Nexus 5.
phone is full stock
bootloader is locked
USB debugging is not enabled
Android 6.0.1
all buttons are working
USB socket is fine
Factory reset from recovery mode is not working - still bootlooping
My purpose is to bring it to live, but I am stuck. Due to locked bootloader I have to use LG Flash Tool. Some time ago I used it with my other Nexus 5 and it was fine - worked excellent. Now I want to do it again with other phone but I am stuck on start: Can't enter download mode (volume up+usb cable). When I am trying to enter to download mode,charging battery icon appears and after few seconds my phone is being recognized as MTP USB device in device manager. I thought it is a problem with the phone, but tried with another working Nexus and there is no difference - it looks like problem with phone-pc connection to me. I tried few cables (original samsung and nokia) and two pc's - no difference. Tried all USB ports etc. Clean reinstall (with registry keys delete) doesn't help, updated version 4.2 neither. Do you have any ideas how to fix it?
Download mode? Never heard of that on the Nexus 5. There is a fastboot mode for flashing stock ROMs and to unlock the bootloader.
I recommend unlocking the bootloader and using NRT to flash a stock ROM.

I have NRT but problem is that to unlock bootloader I have to enable USB debugging - I can't do it with bootlooping phone.
Bootloader can be unlocked without enabling debugging as you are not running adb commands, you need to run fastboot commands.

Thanks! Can I do it with NRT also?
Easiest way to unlock the bootloader on a windows machine is to do this:
make sure that the necessary fast boot drivers are installed;
boot phone into fast boot mode by holding down volume up, volume down, and power;
connect the phone to the computer;
type "fastboot oem unlock" without the quotation marks and press enter key.
Unlocking will wipe the phone.
Once unlocked, you can flash a stock ROM using fastboot commands.

Ok I did it. Do I have to proceed "fastboot reboot" command? when I am doing it it reboots and still bootlooping. When I enter bootloader it is locked again
If the bootloader relocks itself when the phone is rebooted, the memory chip is damaged and will need a motherboard replacement.
I just unlocked bootloader on my S7 and was installing magisk and did everything and got the AP patched magisk file etc, and got to Odin and started flashing only for it to fail with this error
Im not sure what to do as this is the correct verison firmware, I unlocked the bootloader, and flashed everything occardinginly
Did you follow the Magisk Installation Instructions?
After unlocking the bootloader, you have to let the device boot and confirm that OEM Unlocking is still available. Vaultkeeper/Knox Guard are still active even after unlocking the bootloader.

Hmm yeah that's what I thought but thought it was already so because...
I unlocked bootloader in dev options but when I boot into download mode it doesn't give me the prompt to fully open up the device it's just normal download mode :/
I tried booting into recovery and "restart to bootloader option" doesn't even exist, so I had to do it via pc
What should I do?

The OEM Unlocking toggle in Developer Options does not unlock the bootloader on its own. It's simply a "safety" that when enabled allows you to unlock the bootloader.
When you're in download mode, do you see "OEM LOCK" near the top of the screen? Does it say "On"?
To unlock the bootloader, unplug any cables and shut the device down.
Then, hold both VOLUME buttons, and while holding them, insert the USB cable from your PC. The device should start with a prompt - Volume Up for download mode, long press Volume Up for unlock mode, and Volume Down to cancel. Follow the prompts to unlock your device. This will wipe all user data.
Once you've unlocked the bootloader, follow the instructions in the link I posted to ensure Vaultkeeper/Knox Guard are fully disabled.

When I boot into download mode it just shows a normal download screen with no text in the top left, no nothing, it's just normal download. I don't get the option to unlock the bootloader as I've said in my last post
