[Q] stuck at "dual core" but now can't even fastboot?!

I bought one of the refurb'd bionic's a couple months ago. I've rooted and masked the wifi tether, but nothing else, no custom ROMs or anything. phone's been working great for the past seveal weeks since those changes were made, several reboots, etc. no problems until last weekend.
I randomly found my phone stuck on the "dual core" screen one morning. it must have rebooted overnight and been that way for several hours as it was quite hot. I did a battery pull and tried to turn it back on, got nothing. plug it in to the charger, nothing, no leds, nothing. several battery pulls later, still nothing. try to enter fastboot/bootloader by pressing power + volume up/done, nothing. plug it into the computer, nothing.
I'm sorta fearing its been hard bricked (though I have no idea why... i wasn't loading ROMs), except, the other day, after leaving the battery out all night, I was able to get it to turn on, it booted up to the home screen, but before it was usable, rebooted and was stuck on "dual core" again. messing with it some more, I eventually got to the bootloader screen. I wish I had siezed that moment, but i didn't. Messed with it some more yesterday, saw the 'dual core' screen again, but couldn't get it into fastboot. its very hit or miss and I can't do it consistantly, but on rare occasion, it does seem to want to come back to life.
any advice on what happened? where to go from here? and if it can get it back into fastboot? I'm hoping i can and rsdlite will recognize it and I'll try loading 902 fxz back on it, but sure could use some advice to save this phone... no insurance and it was a refurb thats been rooted, I don't think verizon will be too much help.

Try this
Little known hidden key (actually button) sequence: press and hold both volume up & down then hold the power button ten seconds (five should work, but ten always gets it). You should boot into fastboot mode, then flash 902 using a USB cable. You do NOT need to delete data! Check the batch file and REM out or remove any line that says it will. Worst case, Motofail after that will give you access to your latest CWM backup, assuming you have one, just restore that once you have root.

What he said and also you may need to charge your battery.

It could just be a dying phone, I came across an Atrix basically in the same situation. The radio in it had died, so the only way to boot the phone was to skip booting the radio, but if you hit the phone application it would crash the phone.

[Q] [HELP] Something is SERIOUSLY wrong with my Moto G(boot loop)

So. My Moto G is completely un modded, not rooted, and is exactly stock how I bought it and haven't changed any of the software. My Moto G has been getting slower in the past couple of months with everything going slower than usual. I bought my phone in February 2014.
Yesterday while I was at school, in my pocket I had my phone. I felt random vibrations in timed cycles. So I pulled out my phone and had a lol at it randomly rebooted but came back to the home screen. As I started to use it just to send a couple of messages it rebooted again but this time after the reboot animations they just went on and on, what I've found out to be called a boot loop.
So I went home did some research and figured I would have to factory reset. I couldn't get into the phone therefore I had to do it externally. I got the the menu thing ( I think it's called fast boot menu ) and I wanted to select newer bootup or power up just to see if that would possibly stop the boot loop. I selected it and got into my phone, into setting and factory erased my phone.
Well I factory erased my phone and re installed the apps I on,y essentially use or NEED such a social media, within this time there was no unusual activity. Shortly after my phone randomly rebooted ( after downloading the apps ) and turned off, and then went in to the former boot loop! I was furious!
Well here I am, left it overnight for charge and it's been looping for 10 hours. I tried going back into the fast boot menu, the first time I got into it this morning I selected recovery in hope to reset it, however the screen said no command with the android and the exclamation point. The second time I got into the menu I tried 'Factory' and it just rebooted and back into the cycle.
At one point I did get into my phone however shortly after that guess what happened, it turned off and rebooted. And back into the vicious cycle.
I am led to believe it's the power button that's causing the problem ( correct me if I am wrong ) as when I did manage to get I to the phone I did try pressing the power button to investigate this and on some occasions in did lock the phone but in several others it displayed the power off popup and then turned off shortly after indicating that I was holding the button down which I definitely wasn't doing.
So where would I go from this? Do I call Motorola, try flashing a stock ROM ( it's completely stock ATM , I don't know how to do this so if I have to do this can you please explain briefly ) or try going back into the fast boot and go into recovery and try and get rid of no command ( if I can, and how ? ).
Please any help would be very appreciated!
Thanks in advance.
PS you don't think it's the back cover that's doing it because it took that off last night '

Since your phone is completely stock, don't start tempering with it now. Just return the phone. But you have to act quick, warranty is about to expire.

Hi, I had a look online and came across a forum post saying it was a jammed or sticky power button and the poster stated to hit the power button side of the phone on a desk a couple times and it will go back to normal. I'm glad to say it did work after I hit it a couple times, as fast as ever now due to the reset!
I was wondering if I call Motorola would they give me a free new moto g out of it, as I see it as an opportunity to do so, or will they just prompt me to send it so they can repair it under warranty? Is it worth calling ?

Screen won't turn on after 0% battery shutdown

So I sideloaded 5.1 and was fine all day long. Was down to 8% then I notoced the 1% warning 30 seconds later. It shut down before I could plug it in. I booted up and everything seemed normal but the screen wouldn't turn on after the boot screen. I could take a screenshot and power it off but that's it. After a few times cycling it, It started going into the boot as it did when I first installed the update. Optimizing apps, I figured that would fix the problem but sa,e black screen. I tried booting into recovery mode. It just shut it down when I chose that option. I can see the time and unlock screen when I wave my hand over it. Unlocking it does nothing. I get red LED when I hit the power button one time.

I ended up doing a system wipe and it's back to normal now. I'd still like to know the solution in case it happens again.

If it happens again try first to reboot by holding power and volume down buttons for 10 seconds and/or wipe cash

I am having the exact same issue. Has anybody had a luck resolving it short of a factory reset?
My phone battery died last night. I plugged my phone in, let it get about 15% charge, then tried to turn it back on. The phone boots like normal, but after the boot animation goes away, the screen is black. Active notifications still seem to work, and I can hold the power button to get the Power Down option. I can boot into the bootloader & access recovery just fine. However, my phone is fully stock (no root, no bootloader unlock, no anything). I can't seem to access ADB when the phone is powered normally (ie, when I'm at this mysterious black screen), but it's possible that USB debugging isn't even enabled.
So far, I've found a bunch people who've said a full factory reset will fix the problem, but I'm looking for another solution, or at least a way to grab my data before I reset. Since my bootloader's still locked, I can't seem to use fastboot boot to boot into TWRP, and I can't find any other way to access my data to copy it off the phone. I've tried wiping the cache using the stock recovery to no avail. Any suggestions?

Please stop bumping up every topic that says black screen with the same copy and paste message. Once was enough!

Pure 5.1: Boots, has moto display, but black screen when I unlock

So currently I can boot my phone and it displays the boot screen fine. Once its done loading though I just have black screen. Moto display still works and shows new notifications but if I try to unlock the phone its still just the black screen. I can hold down the power button and the power menu shows up fine. I tried clearing the cache but that didn't help. Before I do a factory reset I thought I might see if any one here had some ideas on solutions.
I have the latest 5.1 OTA update. My phone us unlocked, but not rooted. I tried to hook it up to my computer to see if I could at least grab my files off of it, but while it shows up on my computer I can't access any actual files or directories.
I've tried searching around, but I can't find anyone else with a similar issue. Last night my phone battery ran down to zero (and rather quickly compared to normal usage). I may have ****ed it up by trying to get it to boot and be usable while charging but with the battery only at 1% (I guess with the standard charger an in-use Moto X uses power faster than it can take it from the charger). I tried letting it charge for a few minutes and then letting it boot, but after a couple of minutes of use it would shut down again. I finally gave up and let it charge. I didn't really pay attention to its status, but in the middle of the night when I woke up I booted it before falling back to sleep. Not sure there's a connection to my issue and this or not.
Any ideas on what the cause might be or what I can try to do to remedy the issue without data loss?
Edit: I ended up just doing a factory reset and that worked. Admin can feel free to delete this thread if they want.

This sounds similar to the issue here:

This is a bug that needs to be reported to Motorola.

I am that guy from the second post, and I wasn't able to recover the phone. Connecting to PC did not do anything. I would like to ask: is it booting with the new boot animation? Or old one? Because mine showed old animation long after the update was sent out, so I'm thinking the update may have tried to apply and failed, thus breaking the phone. Should all efforts fail, your only bet is to boot into recovery (power + volume up when off, volume down, volume up in the option menu (to select recovery), then hold power when Android robot appears, and while holding it down, press the vol up button once to make the list of recovery options appear. Scroll down to wipe data/factory reset, press power to select, then find Yes to confirm. Good luck!

so this just happened
i came back from a trip and took a whoooole lot of photos. when i came back my battery went to zero and device switched off. i charged the phone to 10-20% and switched it on and all i see is blank screen only moto display is working and power off option is showing itself when i hold the power button which is the same problem as yours
havent done any factory reset yet. is there any way to retreive the photos since i dont want to lose them. there are around 600 and all of them are of the trip.
im on 5.1
there are other people too who faced the same problem and all of them are on 5.1 but there is no solution

Mine did this yesterday, although I'm not entirely certain that the battery hit zero percent. The best I could tell from looking through the logs in recovery was that something was trying to update and failed. I suspect that it was a push from Motorola that hosed it. The only way to fix it is to do a factory reset. Once I did that and restored all my apps the battery was draining at a rate of 40% per hour or so. I found that the package access helper was the culprit and rebooted the phone. Post reboot, I immediately noticed that the boot animation and Moto logo had changed from what they had been on 5.0/5.1 (prior to yesterday). I also noticed that some of the widgets I hadn't reconfigured after the reset were now back. Weird indeed.
Anyway, I have to agree with the others that this is a very bad bug, that needs to be fixed. I am cautiously optimistic that the factory reset has cured it but we'll see. Based on my experience with this phone so far and the sale of Moto to Lenovo, this will be my last Moto phone.

OS Boots to black screen? Anyway to recover data?

Hi all, forgive me if this has already been asked in some form.
My girlfriends Verizon Moto X lost battery one day while she was playing a game. After she charged and tried booting again, it just booted to a black screen. It still runs through the full boot animation. Weirdly enough, active display will still show her information (and can be interacted with until unlocked), and holding power will bring up a power menu for shutdown. The camera gesture also works to launch it, but you can't interact with anything at all. Safe mode provides the exact same issues.
She is running the latest 5.1 update and is fully stock. She also does not wish to root or flash a custom recovery.
I have tried to pull the data, which windows recognizes as a media device, but shows empty when clicked on. OSx immediately says that the storage can not be accessed over android file transfer. I plugged it in for ADB but ADB won't seem to find it when its turned on. It is recognized in fastboot though. I also wiped the cache via the stock recovery, but that didn't help.
I believe a factory reset will be the solution to the black screen, but she has a bunch of photos she would really like to save. Is there anyway for me to actually get them off of the phone? If she can get those, I can get it factory reset for her no problem.
Thanks for any advice!

The exact same thing has happened to my girlfriend's phone as well and I'm also looking for a solution to recover the data. Moto X (2014) Pure, 5.1
The device boots. The Motorola boot animation plays all the way through, the screen brightness dims slightly as normal, and then the Amber Alert from the previous night vibrates the phone several times and displays over a fully black background. There are no soft buttons and no status bar. The home screen appears not to have loaded (yet?)
Attempts to click "OK" to close the alert fail.
The phone is hot. It is working hard. Something stuck in a loop?
The power button will bring up the "Power Off" prompt with no issues. The animation plays smoothly and the phone can be powered off as normal. The phone is able to recognize touch input here.
Calling the phone while it's on will play a ringtone. It is receiving calls.
Plugging the phone into a computer will show up as an MTP device. However, there are no contents listed.
Sometimes, the phone will prompt that the "System" process is not responding and will ask to close it. This has no effect.
Booting into Safe Mode has no effect.
Clearing the application cache from recovery mode has no effect.
I have a CSE degree but absolutely no Android experience. Forensics on a NAND dump or something like that isn't out of the question, unless it's not possible. Hope you're able to get some help.

Update?
Hello,
I am having this issue as well.
Unfortunately I am unable to perform any form of factory reset, the bootloader also just brings me to the black screen and I am unable to use soft keys. The kicker for me is that I cannot connect to my PC with a working USB. I used to have that available and now no device is recognized.
