I have a Motorola Xoom that turns on but it only shows a black screen no Motorola logo or anything. I have tried the volume up and power button but that didn't work. The battery is dead now so I'm thinking of picking up a charger to see if I can get it working. Any ideas on what could be wrong. I think it was dropped at some point.

If you dropped it-> maybe a hardware issue like broken display-controller. If you boot into bootloader mode (from powered-down device, hold power + vol-down) and connect it to your computer (with fastboot set up), does fastboot devices show your xoom?

to clarify this: did your xoom show some random letters or did your command prompt show some random letters?
If your xoom worked correctly, this procedure would make the xoom show "Starting Fastboot protocol support" in addition to the Motorola Dual Core-Logo. >our command prompt/terminal on your computer should show your device's serial number (alphanumeric, like 359C338.....) followed by the word fastboot.
If your computer does show your devices serial number followed by the word fastboot while your xoom doesn't display anything (or just junk), that is a symptom of a hardware failure. I wouldn't try messing with it, instead just take it to your dealer... You should be able to flash the stock rom and/or erase your data using fastboot commands, though.
I know it's Power + Vol Down while booting up to get to the BL, but the soft buttons blink 6 times and then nothing happens.
Then i let go of the buttons, try it again, and nothing happens.
SOmetimes holding Power+volDown works, sometimes it doesnt.
What am i missing here
a program called quickboot. Only works for rooted phones
Or
connect phone to computer
adb reboot recovery
adb reboot bootloader
It's very iffy for me, the best is to use a short cut like quick boot or have an extended power menu. But if you must, power down your device, hold volume down and power for 5 seconds (I countdown like the shuttle is taking off lol) then on 5 release power but hold volume down... Should pop up every time

yea i've been using adb, but that's a hassle when im not at home
i guess i'll be giving the app a shot, but what am i doing wrong with the key presses?
should i do it with the phone off?
while rebooting?
from the OS?
what
how i do it and what i originally read to be the correct button combination is hold down power and volume down for 5 seconds, then release power button while holding volume. should work.

Turn off fastboot in power settings, if it's on when you power off the phone its like sleep, it's not actually off and that would be why it's not working for you.

If you are okay with flashing a better, faster rom compared to stock, CleanROM has this feature from the power menu. Works flawlessly.
Before that, I used adb commands.
I hold down the vol down button, then press and hold the power button for about 2 sec, continuing to hold down the vol down button until you are in the bootloader.
So the vol down button is the trigger for the bootloader.
And you have to have fastboot turned off.

First off I am doing this on behalf of my friend, I don't own a moto G but he does and and so I knew this could be a good place to get help.
Also some crucial information is that the phone is completely stock, not even rooted, and he has had the phone just over a month, so it still has warranty but it would be easier to get it fixed at home then going to a repair centre.
Basically, his phone froze from typing a message, so he held the power button for numerous seconds before it force turned off. He then turned it on, and from what he has told me it seems it did the boot up animation and then gives a black screen, and he can't do anything from there but force turn off. He tried using the 'factory' and 'recovery' buttons in the recovery menu (he pressed power+volume down which I suppose is recovery menu) and they brought him back to a black screen.
Through my knowledge I don't know what could have caused this, or how to fix this, so I've come on the one place that would be able to give help
Sorry if the details are a bit vague but that's all I know, and my friend would appreciate some sort of help to fix.
Thanks in advance

You will enter fastboot mode with power+volume down. Once in fastboot mode you can navigate through the menu using volume down and you can choose an option while pressing volume up.
EDIT: Oh im read somehow that he pressed Volume up. I was wrong with that.
If the problem persists after the recovery/factory reset (if possible) i would recomend you to give that phone to the repair center.
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.

Try this topic and see if it can help you:

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.
I have had my OPO for about 4 years and am currently running Lineage 18.1 with no issues. However the Power button on the phone stopped working and will not do anything. I inadvertently put it in Fastboot and cannot get out of Fastboot and reboot to normal. I have tried adb to see if I could do a reboot there but it is not detecting any devices. Before this incident the phone was unlocked, in developer mode with usb debugging set. Is there some other sequence to try. I have tried vol down and plug in usb, and vol up and plug in usb, and held vol up and down and plug in usb but none have worked. Any suggestions please.
Update: I just got Fastboot on the PC to reboot the phone. Yea. The Power button is shot. It has been in a case for years and I hardly ever use the Power button anymore. Don't know why it has failed, no abuse, maybe lack of use. Thanks anyway.
If I take the button out, does anyone know if the inner switch could be pressed with something to turn it on and off. I assume there would be somethin like that although I have not been inside one of these before. If I ever lose power on the phone I will not be able to turn it back on without the power button/switch.
