So this morning i tried this. Kingroot didn't complete the root, some error happened, i didn't mind since i was just testing to see if i could root my phone for the first time [i've never done it before and it seemed simple enough].
I quit the app, a bunch of errors showed up, one after the other [i didn't register what exactly the windows said, i'm pretty sure it was a google application that stopped working]. The phone turned itself off.
i booted it up again, and it showed me the AP Fastboot Flash Mode screen. i know this from previously doing a factory reset, so i tried doing it again. After it wiped all of my data and custom, i tried rebooting it.
it showed me the motorola icon, but a few seconds later, i was back at the fastboot screen. i'm pretty desperate right now since this is my only phone. i tried selecting the "normal powerup" command, it didn't work. this is my screen right now:
"hab check failed for boot
failed to validate boot image
fastboot reason: fall-through from normal boot mode
USB conected
hab check failed for boot
failed to validate boot image
boot up failed"
none of the other commands, aside from Recovery, work. it takes me to the no command screen and all of the known options once i use the power+volume up command: reboot system now, reboot to bootloader, apply update from ABD, etc.
sorry if this thread reads weird, i'm sort of freaking out right now and english isn't my main language. thanks in advance to anyone who might help!

If you have questions PM me I will try to help. I got the same problem on Monday and solved it yesterday.

I have a stock Verizon Moto X (XT1060) that was running 4.4.4. I was on a flight Friday using the phone in airplane mode to run Spotify and Podkicker - noticed the phone was running a little hot so I shut the apps down for a while. Anyway, upon landing I take the phone off airplane mode and the usual minor flood of emails/texts/updates comes in. About 30 seconds after this the phone begins alternately flashing "Process android.process.acore has stopped" and "Process android.process.media has stopped." These cycled for about 5 displays of each, then would disappear for about 45 seconds, then start again. Tried resetting the phone, letting the battery die, no success.
Saturday I tried to navigate into settings to do a factory reset, but the screen froze whenever I tapped on the "backup and reset" menu. Could access all the other menus from settings (until the error cascade started again....). I was able to boot the phone into recovery mode and wiped the cache - nothing. Went back into recovery mode to do a factory reset and now I appear to be stuck in a boot loop - the Moto logo pops up, buzzes, and then does nothing for about a minute or two before trying again. I can get it into recovery mode and tried to wipe the cache and factory reset again, but still nothing.
Any thoughts? Tried looking at other threads but didn't seem to find anything like this. Thanks!

No luck, unfortunately. Still stuck on the Moto screen. I can force the phone to reset by holding down the power button and then get it into fastboot, my computer recognizes the fastboot device, and the code seems to have run fine. Thanks for the idea - any other thoughts?
If you can still get into fastboot mode you can try flashing only the stock 4.4.4 system.img via mfastboot. That will not wipe your data. If that does not work I would do a full return to stock via mfastboot or you can use rsd.
Thanks Travis I'll give it a shot. I never enabled USB debugging and never unlocked my phone before this happened - I imagine I'll need to try and unlock the bootloader first, no?

No, don't need to unlock boot loader to flash the system.img just enable USB debugging in developer options. Tap build number 5 times to enable developer options. If you have never flashed anything before via fastboot rsd might be easier for you.
Thanks - I've used fastboot before on an older phone but never enabled USB debugging on this phone and now can't get to enable it since I'm stuck with this boot loop. Downloading the files from Moto now so will give it a shot tonight anyway. Can't really break it more than it's already broken since all I've got now is a shiny light up paperweight.
You will still need to download the stock images for 4.4.4 for Verizon and extract them. You can flash via rsd or simply flash just the system by running the command "mfastboot flash system system.img"
You will have to have the image file in the same folder as your mfastboot.exe I usually keep all mine in platform tools.
Sigh. Got everything downloaded but when I tried to flash either the boot image, recovery image, or system image, I ran into errors
Here's what displayed (sub boot/recovery for system - same basic error):
c:\{Path}\mfastboot flash system system.img
(bootloader) Variable not supported!
target max-download-size: 768MB
Multi-Flash is enabled!
sending 'system' (262144 KB)...
OKAY [16.793s]
writing 'system'...

I was following option 5 from mark @ cdma forum's guide to return motox to stock (can't link b/c I don't have enough posts...) . No issues until I got to the flash boot boot.img step.
I'm assuming this is due to not having USB debugging enabled prior to my phone eating itself, though I'm not sure. Willing to try other things since I love my Moto X but my cheap replacement phone arrives tomorrow (hopefully) so at least its not the end of the world...
You are sure you got the 4.4.4 images? You did not try to downgrade right?
Yup. Definitely got the 4.4.4 images (went back to the Moto site and it will let me download the 4.4.4 immediately but made me request authorization for 4.4.2) and I know I was running the most recent version since I checked for an upgrade on my phone last week in the hope that Moto had released 5.0.
You are following this guide? http://forum.xda-developers.com/moto-x/general/guide-moto-x-return-to-100-stock-using-t2446515
If USB debugging is not on you can manually boot you device to boot loader mode. Then fastboot or rsd should work fine.

I appreciate the help...but still no luck. That's basically what I've been doing and I went back through following those instructions - at every step I get the "variable not supported" error and then it fails at the flash boot step with the error message I described earlier.

You are opening the cmd screen from the same folder as your images and fastboot and mfastboot.exe correct? From your error it looks like your cmd screen is directed to your "C" drive.
Sorry, just didn't type out the whole thing - the cmd path is to the platform-tools folder where all of the files are also located...
Damn was hoping it was something simply like that. Have you tried rsd?
I haven't - didn't enable USB debugging and for whatever reason the package I downloaded from Moto doesn't include the XML file of instructions. Most of the links from the youtube video and some of the links from the XDA guide earlier are also dead so seems like I'm pretty much out of options. Thanks for all of your help - guess I'm going with the $80 replacement till I'm up for an upgrade!
So as my friend was sleeping last night apperently his phone was hardbricekd. When he woke up it wouldn't leave the screen: boot up failed. Failed to validate boot image: ret=-1. He texted me from his pc asking for help. I told him to boot into recovery and just reflash stop. When he tried it said: Fastboot demon: failed to initialize partition table. What can he do??? It was stock and hadn't been rooted in a very long time!
Same problem: Stuck in fastboot
I'm having the same issue. After having 6.0 for a few days, my Nexus 6 shutdown while I was using it. It will only boot into Fastboot mode, with the same errors. I finally got adb to recognize it when plugged into my computer, but don't really know how to proceed. The command "fastboot oem unlock" says I need to allow this option on my phone, but I can only get into fastboot so that's impossible. All the guides I see to flash anything require this step.
I've done some digging. http://forum.xda-developers.com/nexus-6/help/stuck-fastboot-flash-to-recovery-t3266921 ... This forum suggests it's not fixable by a home user, but if anyone else has more info please let me know. You guys on xda are infinitely more knowledgeable than I am on this.
Nevermind. A little more reading, and I understand more of the jargon. Locked bootloader, no TWRP = no bueno. RMA is my only option. Guess I'll order a Nexus 5X and take steps to make sure this won't happen again.
Hello XDA,
Ok, so I'm going to try to explain the best I can. My roommate has a Nexus 6 (Project Fi if that matters). She went to install an update, although I'm not sure which one. She said she thinks it was "7 something". I'm assuming it was 7.1.1 since that is the one that I was last notified about on my phone and she said the notification appeared only a few days ago. After she installed it the phone was stuck in a bootloop (the spinning colored balls screen).
I Googled solutions and tried wiping system cache from recovery mode. That didn't work, so I asked if she had anything important on the phone and if I could do a factory reset. She said I could go ahead and do it, however that did not work either. So then I plugged the phone into my computer and fired up a terminal session to flash a factory image to the phone. I entered "fastboot oem unlock" so I could proceed . It came back with the "see developer options" message. Ok, cool, but I can't get into the settings app to enable OEM unlocking.
So since I did the factory reset and can't boot into the OS, is there any way to enable OEM unlocking from the bootloader? I'll keep looking for answers in the mean time.
Thanks in advanced.
EDIT:
Found a thread with the OP having similar issues. I tried "fastboot format cache" and "fastboot format userdata" which both failed with "Not allowed in locked state!". Even though I got the errors I tried (out of desperation) to boot to TWRP with "fastboot boot ~/Downloads/twrp-3.1.0-0-shamu.img" which failed with "FAILED (remote failure)".
EDIT2:
Tried downloading 7.1.1 OTA image and sideloading via "adb sideload shamu-ota.zip" from the bootloader recovery mode. Failed with "error: no devices/emulators found".
Sideload an OTA image. That should resolve the bootloop so you can enter Android to unlock the bootloader.

Thanks for the reply. I tried it and it failed with "no device found". The command "adb devices" gives me an empty list. Not even ????????.
If ADB isn't seeing the device you potentially have a hardware issue.
i got same problem.
no oem unlock cuz is in bootloop
locked
erasing
@luisq93: Yours is a different issue. The solution for you is to do...nothing.
The erase part of the factory reset MUST complete, or you may end up with unusable internal storage until an uninterrupted factory reset is completed. So all you can do is be patient.

like 2 month and half patient?
cuz the erasing changed language 2 months ago and nothing more... from italian to English, maybe i should just wait... thanks for the advice.
@luisq93: How long did you leave the N6 running the very first time the device started erasing? I'm willing to bet you only gave it a few minutes, became impatient, shut the device down to restart it and upon restarting encountered the erase mode again. Consequently you thought it bootlooped and put it in your drawer.
Until you let erase mode complete, every time the device boots it will immediately enter erase mode, because the erase must complete to avoid corrupting the internal storage. Erase mode, especially on an encrypted phone, may take a while. I had one instance on another of my devices take an hour.
So the solution to the erasing "bootloop" is to do nothing except plug the N6 into its charger and leave it alone.

Focus on left inferior corner shows the message "device unlocked", in addition i cant put on fastboot mode.
Some moments before i was on i bootloop in twrp and i also cannot flash another boot image, because the adb in cmd said that wasnt a "image", so i decided to erase boot, bootloader, system to try to get out. However i entered in another bootloop that is mencioned on video.
I charged my Mi A2 overnight and woke this morning to find that it won't boot past the Mi A2 splash screen; it shows the splash screen for a few of seconds and then dies. I read advice to hold down power and 'up' keys, this just resulted in the same. I tried power and 'down' key and that got me as far as the Fast Boot splash screen, but no further (phone just continued to display that splash screen). I've tried taking the SIM out and turning it on - no change. I tried opening it up and disconnecting the battery for 3 minutes - no change. I'd be very grateful if anyone could suggest a fix. I know this is hugely unhelpful, but I can't remember what I did to the phone in terms of unlocking the bootloader and/or rooting, but I have a feeling I left it stock (I've owned the phone for a couple of years and haven't changed anything material since initial setup).
Disclaimer: you need adb tools to execute following command. You can find info where your wish about it.
Try to make it on FastBoot mode, then attach to PC and execute
fastboot reboot
If it brings you again to flashing screen, again, bring the phone in fastboot mode. Then try to change active slot.
fastboot --set-active=a
If not working with a, try with b. After setting it, launch the command to reboot again.
What recovery do you have? Pressing up + power when turning on where brings you?

Thank you very much for your help.
Executing fastboot reboot via adb just brought me back to the Android One splash screen for a few seconds before the screen went black.
Changing the active slot to both A and B gave me the following error message:
FAILED (remote: 'Slot Change is not allowed in Lock State')
Pressing up + power when turning on just brought me to the Android One splash screen for a few seconds before the screen went black. I held those two buttons down for several minutes and the same thing kept happening: splash screen followed by black, repeatedly.
Is there anything else I can try?
You can try fastboot oem unlock or
fastboot flashing unlock to try to fix the "Locked State".
If I'm not wrong it erases your data! Before doing it please be sure and wait for some more time: maybe there is another solution for it!!!
Main reason I'm making you this steps is that I think your phone applied some kind of system update that break something. Thanks to A/B partition maybe you can have a working system on the "not corrupted" one, so I'm trying to get you into it (either A or B)
Remember that doing this commands sometimes make the situation worse, or format your data, so please read if there are any side effects.
If nothing will work you can try to wait for someone more expert than me. Maybe you have a chance to recover from this state.
Another thing: turn on the phone (normally) without holding it in charge. I had a bug that won't let me pass the splash screen if phone was charging.
If really nothing works, try to find a tutorial on how to flash a ROM via TWRP, there are plenty of them. You will probably loose your data.
