[Q] Nexus 10 will not boot after unlocking bootloader

Hello all,
I am trying to install Cyanogenmod on my Nexus 10. I followed the instructions on the Cyanogenmod wiki (I can't link to them as a new user). I got as far as these instructions to unlock the device:
Enable USB debugging on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type the following to boot the device into fastboot mode:
Code:
$ adb reboot bootloader
From the same terminal, type the following command to unlock the bootloader (under Linux, you must be root):
Code:
$ fastboot oem unlock
A disclaimer will display on the device that must be accepted. Use the volume keys to cycle through the options. Pressing the power button should confirm your selection.
If the device doesn't automatically reboot, reboot it from the menu. It should now be unlocked. You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots.
However, the device never rebooted. It just shows the glowy nexus X logo indefinitely. If I reboot to the bootloader, I get options for recovery mode, however the device does not show up on fastboot or adb from my computer in recovery mode, so I don't know what to do.
I am new to the world of unlocking and custom roms and whatnot, and am worried that I just bricked my tablet . Thanks for reading.

OK, I found the answer searching online. A video on youtube explains it. The forum won't let me link the video, but the youtube id is T1Se7Hr9Cww. Put that after the "v=" in a youtube URL and you'll get there.
explains how to fix it. Evidently unlocking the boot loader doesn't reset the device, but the device must be reset to continue. So you need to do mash all the buttons in recovery mode to bring up a menu to delete your stuff.

[Q] Can't go through boot animation in any rom

Hey guys, I had Lollipop 5.0 and I did stock rom flash in Nexus Root Toolkit to install 5.0.1, everything went smoothly and it started to boot, I waited for more than 20 minutes. Then I decided to do it again and it was really hard to get into fastboot, I had to disconnect the battery and try for some more time. When I finnaly get into fastboot mode I have tried reinstalling 5.0.1, installing 5.0, 4.4.4 and even Cyanogen's last nightly. With any of those I had no luck as it is stuck with boot animation.
Some googling told me about people who did fastboot oem lock and it booted up, just tried that with no luck also.
One very important thing, when I get into fastboot mode, I can only select Start in the device itself, clicking volume up or down doesn't give me any other option.
Edit: I even downgraded Nexus Root Toolkit from 1.9.9 to 1.8.2 thinking it was the problem, no luck. And tried to install Lollipop manually a couple of times. And the problem trying to get into fastboot mode keeps happening.
Thank you all in advance

And now that I tried to lock the bootloader I can't unlock it again because when I go to fastboot mode I can only press start, pressing the volume keys doesn't do anything. What can I do to unlock the bootloader ? I think I'm stuck in here because I can't do anything else without it unlocked.
Edit: It didn't work to boot the system also
I really need some help here

so your volume down key is working when you're entering bootloader mode, but after "fastboot oem unlock" command you can't choose "YES" with the same volume down key ?

All my keys are working just fine, I can easily boot into bootloader (I was doing Power + Volume Down when I should push Power + Volume Down + Volume UP) but when I get into bootloader/fastboot (I don't know which one is the proper name) I can't do anything but press the Power button, meaning that I can only choose START. When I do the fastboot oem unlock command I can't press Volume UP or Down to choose Yes.
I followed this tutorial (http://forum.xda-developers.com/nexus-4/general/tutorial-how-to-unbrick-n4-t2347060) with no luck aswell, I finnaly got into the system, but I can't unlock the bootloader because of the Volume keys problem. I also noticed that even when I'm into the system from that tutorial, which is Jelly Bean btw I still can't use the volume keys.
Basically, phone only recognises volume keys when it's off and I press to go into bootloader or download mode.

When my phone is in fastboot I don't see it on cmd "adb devices".

I tried with different drivers etc. but its just don't work, i downloaded TOOL ALL IN ONE, but this said that device was found but not said what or which device, only when phone is normally started i see it on the list of "adb devices" and in TOOL ALL IN ONE. Please help thanks in advance =)

Fastboot is an entirely different mode from adb, and as such it requires a different tool. In the console there is a command "fastboot", which is what you need to use to interact with the phone in fastboot mode. You can boot into fastboot mode from power off with the USB to computer plugged in by holding Volume Down, or it might be possible with TOOL ALL IN ONE, I haven't used it much.
Some basic commands:
fastboot flash unlock path/to/unlock.bin # This will flash the unlock bin
fastboot getvar unlocked # This will check if the device is unlocked
fastboot reboot # This will reboot the phone into normal mode, since powering off by holding the power button is a pain
To flash TWRP, there's a more advanced process with some specific requirements, but I'd be happy to share those if wanted.

First of all, which version of G6 do you have? The US997 one, or the H870?

H870

For H870 I'm not entirely sure, but I know that for the US997 you have to do a special procedure to make it permanent. Make sure you back up everything first, too.
With the phone in fastboot mode and a computer connected with fastboot installed and the twrp zip downloaded as "twrp.zip" (or whatever you want):
Make sure the bootloader is unlocked: fastboot getvar unlocked (should return "yes" or "true").
Flash the recovery: fastboot flash recovery twrp.zip (replace twrp.zip with the relative or absolute filepath/name).
Unplug the phone from the computer and reboot into recovery by holding Power and Volume Down. When the logo appears, lift your finger off the power button briefly and then continue pressing.
When you get to the factory reset menu hit yes twice, then the phone should boot into twrp (it may flash the LG logo, I've had different behavior on different phones. You won't need to hold the Power-Volume Down combo any more).
In twrp, swipe to allow modification, then in the Wipe menu select Format Data (and enter yes). This will wipe the phone, so make sure everything was backed up beforehand.
From the main menu go to the Reboot menu and select Recovery.
Here it might vary from the US997. Below are suggestions which I think are needed to have it work.
Download the no-verity-opt-encrypt zip, and connect the phone to the computer.
Once it's rebooted into recovery mode: adb push path/to/no-verity.zip /sdcard/
Then from the install menu in twrp install the zip.
Reboot into System from the reboot menu on the homescreen of twrp.
That should do it all.

Fastboot/download mode?

Does this phone have? Is there a way to boot into such mode so I can flash something via fastboot?
Power and volume down keys just lead to some test mode. Holding the volume down while connecting USB does nothing as well.

I'm just having the same prob with --U51

Thanks

Not meaning to necrorez a thread as the entire forum section is inactive...
On Y625-U21 the best way to enter fastboot mode is via adb:
- activate usb debug
- use "adb reboot bootloader"
you are now in fastboot mode. Notice that on the phone you won't see a special screen: just the huawei logo like it's stuck, but you can use fastboot to do what you want (unlock the bootloader since it won't require codes, run TWRP, flash TWRP etc etc...)
