Stuck in bootloop, can't get to recovery

I have a Moto G XT1034 that is stuck in a boot loop. I am not able to get to fastboot or recovery, it just keeps rebooting over and over again. It started at about 50% battery, now it's at 0% even though it's been plugged in for most of that time. This device has an unlocked bootloader, is rooted, and has been running kitkat for almost a year. Nothing that I can think of has changed today.
Things I have tried:
Holding vol up + vol down + power for 4 seconds
Holding vol down + power for 4 seconds
Holding power for 120 seconds
Letting the battery drain completely, and then plugging it in. It just starts with the reboot cycle again.
Any ideas?
That doesn't seem right. Try holding volume down and power for longer than 4 seconds.
Here's a video of me holding vol down + power for 120 seconds, as advised in Q28 of this sticky. Doesn't get me to fastboot.
I have a second moto g here, and have swapped the batteries, so the broken one has a fully charged battery. The bootloop continues when fully changed. Video here. Holding vol down + power for a few seconds, or 120 seconds also doesn't do anything when fully charged.

flash costom recovery....using adb fastboot command
Thanks for the replies.
I am not able to power it off. I have found two ways of "powering off" which are to either let the battery drain, or to hold buttons during the black screen part of the boot loop.
If I wait for the black screen part of the boot loop, and quickly press vol down + power, it will stay black as long as I'm holding those buttons. If I hold them for 4 second and release, it then enters the boot loop a few seconds later. If I hold them for 120 seconds and release, it does the same thing a few seconds after releasing.
I am not able to open an adb connection to the device. "adb devices" shows no devices in all phases of the boot loop.
To predict future concerns, I have the proper drivers, and have used adb quite a bit to work with this device. Also I can use adb on the second moto g with no problems. So my pc is set up and configured correctly.

Just remember to acess it when you have time to do all the tutorials that I've linked. Doing it with attention probably will solve your problem;
:good:
BobDiaz thanks for the suggestion. I still can't get to fastboot though, so this never does anything other than "waiting for device" If i plug in my second moto g, of course, then mfastboot works fine once I boot into fastboot.

in black screen you must do vol+power process 2 times..... first time nothing happen... in second time you press the power+ volume down the fastboot menu is shown...
That's very strange. Makes me think there's a hardware problem. The only point I can mention (sure you've tried this, but just to be sure) is to keep it simple: if your phone doesn't reboot after holding the power button down for about 10 seconds (with or without pressing the vol down button), then you almost certainly have hit a hardware issue. Especially if you've taken the lengths of swapping batteries and not seeing a difference.
I know that with my 1st gen Moto G, when I'm stuck in a boot loop after too much mucking around, I just hold vol down and power for ten or so seconds, and then it boots into fastboot mode. That's how the phone was designed. Best of luck.
Correction: the phone shuts down in just over ten seconds, and when it does I let go of the power button but continue holding the volume down key for several more seconds before I reach fastboot. As well, since I'm about to use fastboot, I've always got my phone plugged into USB when I do this. But, I just tried it unplugged, and it worked the same.
Try pulling the battery then holding up on volume and power button and home same time

Hi TracvisTx, T
I just ran into exactly the same issue as you have mentioned here.
After doing downgrade from Lollipop to Kitkat, my moto g is stuck at bootloader warning. It power on's, gets stuck on warning, reboots. Does not charge to more than 0%.
I was wondering if you could come out of this issue and how? I am also unable to enter into fastboot mode! I have tried all the described combinations of power + vol (up/down) buttons.
Please help.
Thanks,
@beerbarfly - Hold vol down (or up) while turning on wall charger.

You said the phone is bootlooping - hold vol down (or up) immediately after reboot.

lost101,
The screen blanks out, then it shows battery charging (0%), then goes to "bootloader unlocked warning" and then back to black screen.
In all this, even if you keep vol + power buttons pressed, nothing happens.
Infact, if it is in blacked-out screen step, and i keep these buttons pressed, it remains in black-out, does not even go to charging screen....
Looks like that is what is called as bricked phone

Only hold either Vol up or down - forget about power button.

[q] [help] hard bricked (?)

Here's my nexus condition:
It won't turn on, i've tried every possible method; hold power button (10s), hold volume down + power,
volume up + power, volume down + up + power, It still won't turn on.
I connected it to charger and it entered google logo but then off and on for several times. I sometime managed to get
into bootloader mode, but then again it off again.
the interesting part is when i hit my nexus to my palm, it sometimes turn on and enters google logo but then bang,
it's back off again.
Could someone please help me get out of this misery?

Sounds like a problem with the power button.
It should be a problem of power button cause if its has gone inside.. it will always keep shutting your phone

Phone won't boot up

I have researched the "related threads" and none are similar to the issue I am having.
The phone turned off midcall and fails to turn on afterwards. I thought it was the battery, but it still fails to turn on after charging over night.
It boots up to show the logo, after a battery pull and turns back off.
If I I press down the power button + down volume+ menu, I get the warning about a custom install of an OS may damage the phone and if i want to continue to press the volume up, or cancel.
The phone only lasts about 5 seconds, after every battery pull, other wise it won't turn on again.
I haven't gotten a blank white screen nor the Android logo.
Thank you.
Update: I believe I confirmed it is a power button issue.
What I used to confirm it was pressing the volume down button and menu without the power button and was able to see the Warning as if I had pressed all three. Also, the phone vibrates as soon as I place in the battery.
Issue now is: Supposedly the cause is due to a stuck power button, but physically the power button is not stuck. It clicks when pressed.

Powered off, no charge light or power on

Hey all, I searched around, just haven't found the answer I'm looking for.
First, I did get it to bootup after holding Power+vol up/down, and I'm trying to understand what happened.
Running stock Verizon 4.4.2
Bootloader unlocked, S-off
Rooted
The phone was at about 75% charge and I was viewing gallery. I noticed that videos were no longer playing and was trying to get one up. The phone suddenly went black as if it powered off. I pushed the power button- nothing. Held the power button - nothing. Did that a couple more times for longer.
Then hooked it to charge - no light, nothing.
After a quick search I found a suggestion to hold power+vol up/down 1-2 minutes. I did that and it booted in about 15 seconds.
My question is, what happened? why?
Is there a way to avoid it?
And if it does it again what is the best way to get it restarted?
I still plan on flashing a newer ROM, just haven't done it yet.
Thanks
Really, no thoughts on this? Phone goes blank, won't restart. Someone on XDA must at least seen it.
Happened to me once but due to my own mistake.
I wanted to boot phone into bootloader, instead of shutting and then pressing vol down + power, i forced shut the phone by pressing power + vol up, here is where i commited the mistake, instead of holding the buttons for 7 secs( after which the phone should go off) i held them a bit longer mayb 15-20 sec, after tht i tried to boot into bootloader by pressing v up + power , nothing happened, did that several times, again nothing. Tried to power it on, nothing, connected to usb, again nothing.
It seemed like i had hard bricked the phone(thoughts of losing the phone came to my mind) but after trying and trying and trying again and again. It did got up(i held vol up + power for 7-10 sec, without releasing the power button, and releasing the vol up button, instantly held vol down button and it booted to bootloader).
Mayb the phone enters into some other kind of mode which only HTC is aware of.
Thanks piyushkohli97 for the reply.
Hasn't any developers run into this? Or someone with an understanding of the issue? It doesn't seem uncommon. I'm hoping to gain some insight into the issue. Anyone else?

benq f52 boot loop

Hi,
I tried to root my phone by using the kingo root application, after 90% it just rebooted and now hangs in a boot loop.
I try to enter the factory reset mode, but when I press power + volume up it only vibrates. There is no home button on this phone. I also tried pressing all 3 buttons power, vol up and down, which just turned the phone off now finally, but I can't get into the factory reset mode. Also power plus volume down just reboot the phone.
//EDit: In case someone has the same issue: Power off the phone by pressing all 3 buttons, after that wait for 10 minutes then power on the phone by pressing power plus volume down until the android logo appears, stop pressing the power button and keep pressing volume down.
