Does anyone know how to get the phone off in this situation:
I'm trying to access the bootloader to fix something of a boot loop, but can't get it to turn off so that I can do power+vol down. It doesn't automatically loop, but it stays stuck in "Android is starting....Starting apps." Holding the power button pulls it out of that, but it just goes right back into booting up, optimizing apps (taking a long time as it usually does if you have a lot of apps), then stuck again at starting apps. It will start the boot no matter what I try. Holding power continuously; holding it just until the screen goes off then letting go; holding vol up or vol down with power once the screen goes off; holding both the whole time. No matter what, it goes into boot animation then everything mentioned above.
I can't think of anything else to try.
To give you as much of the picture as possible, this started after restoring a nandroid through TWRP, clearing cache and booting. Didn't get any errors on the restore. I've restored nandroid's on this phone before without issue, so I'm not sure what's going.
Anyone know how to get the phone to power off in this loop?
Man I miss removable batteries!!
I just got done chatting with Moto support, and I'll leave this here in case anyone else runs into this problem:
Hold power + vol down for 3 minutes then release. That should get you into the bootloader.
It worked for me, and hopefully its a universal fix for anyone in this situation.

Does not work for me anymore, and figures I find this out when I get a bootloop.
So yea basically I keep getting clear storage popping up, but after countless attempts and even holding home once I get passed clear storage it stays on the htc logo until I eventually release it and then it tries to boot the phone.
Of course the usb isn't enabled at that point too so I can't connect through adb. I don't know why it won't let me go into recovery but...
Pull Battery,
Volume down + End key
Home key
Your in Recovery
Unless I'm missing the point of this thread?
Correct me please.
Ah thanks.
Yea it suddenly started working again, but I swear home+power stopped working for like 20 tries or something.
Weird stuff but I'm all good
So.... Been playing with this for the last two days trying to root this phone.
I've rooted a few other phones, so I do have experience with the overall process, but I am unable to even boot this phone into Recovery. I have tried booting into recovery by holding down both volume buttons + power and from adb terminal "adb reboot recovery."
Neither method works. The phone will boot (or reboot from adb) and brings up the "at&t World Phone" screen and then nothing else appears. The first time I tried this it actually wouldn't boot up even after pulling the battery and trying to start normally, it still sat at the same screen. I let it sit all day today at the screen until the battery died. I was finally able to get it to boot up earlier.
If anyone can help, that'd be greatly appreciated. Let me know what info I need to add.
I usually just press and hold both volume buttons and power then release just the power button and keeping the volume buttons still pushed on the 2nd time the white at&t screen pops up... Works for me every time.

hold volume up+down and power key btw this is wrong section to post supposed to be in general
Oh sorry, didn't realize it was supposed to be posted in general.
I've tried the Volume Up/Down + Power and this does not work, as I stated originally.
I've also tried to do it from the adb shell, which also does not work.
Does anyone have any idea why I can't access recovery?
I"m having a similar issue. Holding volume up+down and power and releasing in any combination just boots the phone up. If I just hold volume up+down and power the phone alternates between the AT&T World Phone screen endless.
Yes u have to let go of the pwr button when the phone screen turns on

I've tried just about every combination of the Volume Up/Down + Power and no luck.
I've also tried the following ADB commands, with no luck, it just reboots the phone:
adb reboot recovery
adb reboot-boatloader
When I hold Volume Down + Power I get the a Yellow Triangle with a Android guy with a shove with the text "Downloading... Do not turn off Target!!!"
When I hold Volume Up + Power I get an Android guy with the following text: "POWER RESET or UNKNOWN UPLOAD MODE"
For kicks, I tried to to flash a rooted update.zip via the Volume Down + Power way with the Samsung update software, the same way I have done with the Samsung Moment. Wasn't sure if it'd work, but worth a try.
Any one else have any ideas or suggestions?
Phishie, do you have a final release version? Or anything special about the phone you have?
I just press the two volume buttons first (to make sure theyre pressed before you hit power), then press the power button, as soon as the screen turns on, I let go of everything and it works just fine, no need to have ridiculously complicated instructions.
The trick is to make sure both volume buttons are pressed BEFORE you hit power. Then release. Easy as pie
Also, if you guys are having too much trouble, just download the one click root/unroot. It will run, boot your phone into recovery, then all you have to do is scroll to install packages with volume key and hit power. Done.
Trust me, I am making sure I'm pretty the keys completely. I've literally tried it fifty times by now.
And I've also tried the One Click Root. This does not boot the phone into recovery either. It just sits at the AT&T World Phone screen forever and will actually get stuck here and will not boot up normal even by pulling the battery and powering it back up. It'll just get stuck at the for-mentioned screen. I have to connect it to adb and reboot it there to get it out of the loop it's stuck in.
that doesnt sound good. Maybe you need to try a factory reset? are you running stock rom and everything?
When I first got the phone I did a factory reset.
Yea, it's completely stock to my knowledge. But I have a different ROM than the final release version that everyone else has. This is a pre-production device.
same problem
I try all the combos as well, no luck, would the combos be different for 2e vs 3e recovery?
I try combo, it powers on, the same thing happens, the at-t comes up, goes for a second, then screen brightens, wait a bit and then the home row buttons light up, hangs there... doesnt matter which kernel or which rom I flash, same thing, adb and other stuff wont work as they need usb debugging enabled, which mine isn't.
Is there a way to mod the phone files and flash to enable usb debugging? Anyway to remap the buttons to 2 button vs 3 button?
Everyone post your methods for entering recovery please?
Hello,
I've just installed this ROM after wiping Cache/Delvik Cache and system wipe.
Now the phone is stuck on the boot screen and I can not get back into recovery to sort it out.
I held down power & vol+ buttons to get into recovery but nothing happens. The Home & Back buttons flash after 3 seconds then nothing happens.
Any thing else I should do to get into recovery ( TWRP)
My friend whop is a member asked this question on the Developers forum and so far no luck.
we have tried the following:
This is suggested by chogardjr: Plug your phone in to charge. Don't use a USB port for power. After you plug it in try the hard reboot again.
PLEASE HELP
Just for the sake of testing... Have him hold power without holding the volume. It should force reboot, not to the bootloader, so he can get a feel for how the reboot works. It can be finicky during a bootloop cause there are processes trying to run in the background. But it should do it if you hold power long enough.
Edit:
Also find out if the charge light comes on when he plus it in.
Tried and no joy.......

I had a similar problem with a bad kernel flash and could not get the device to shut all the way off - thats why the keys are blinking. I plugged it in to a charger, left it like that for a few seconds, then unplugged, held it under a bright light and waited. After a few more seconds, it shut all the way down and I was able to boot to recovery in the usual way (power+down). You may have to try combinations or maybe not. But, you won't get to recovery until the phone shuts all the way down. High light under in the 'eyes', plugging and unplugging, and holding the power button for up to 30 seconds are all known ways to do this, but as was said before a bootloop has processes trying to run, so the machine can be 'confused' and have difficulty shutting down. Hope you are successful...
Thanks. I actually got it going with one of the answers posted for me, by powering it off under a bright light.
Sounds daft, but it works.
My Galaxy Exhibit II 4G is about a year old, rooted and i have CM11 installed. Everything was fine, I had it plugged in (charging) and i was downloading an app (Camscanner) from the Mobogenie store when suddenly the phone shut off and the battery icon appeared with the loading circle in the middle.
This did not stay on for long as the screen would go off and this would again appear. After pulling the battery and removing the charger, then reinserting the battery, the phone would just flash the SAMSUNG logo in this very same manner.
I am unable to get into either recovery or download modes and when i try this combination (VOL UP + VOL DWN) i get:
RAMDUMP MODE
Cause: Force Upload
I have been reading forums for hours and i have found nothing. Is my device bricked? What can I do to recover it? Please, any help would be greatly appreciated :crying:
What happens if you try vol. up + power, or vol. down + power?

Thanks for replying. Nothing happens. It just continues to reboot like I'm not doing anything. The only way I'll get a reaction out of it is with vol up + vol down
It can be tricky. This post may be clear http://forum.xda-developers.com/showpost.php?p=32437850&postcount=6
The link you sent me to sounds similar to my problem, except I wasn't trying to update the firmware. The crash was spontaneous.
However, neither of those methods work. As soon as I put in the battery the SAMSUNG logo appears, then disappears and reappears and it continues like that... Pressing the power button does nothing, whether by itself or with the volume up/down button
I am beginning to panic
What happens when it's connected to power?

Anyway, after many hours of investigation I discovered it was a hardware problem. The power button was stuck and so it forced it to reboot repeatedly. It also explains why it (the power button) was unresponsive. Disassembling the phone and freeing up the power button solved the problem.
P.s. Your build of CM11 is boss
I have same problem with power button. Had to tweak it hard cause it was so sensitive.
It's the first time it's happened to me. Probably because I dropped it so many times
Strange, ...

OK so I'm no expert or anything but maybe my experience with this Model might be able to help you a little bit. I have the same model and it was doing the exact same thing however I haven't rooted it. And I've since corrected the issue on mind particularly it appeared that it was the charge port and/or USB that either had a bad connection or possibly it was boot looped. However with me not rooting the I didn't understand how it could be booted Looped so I started playing around with holding the power button playin with USB things of this nature and what I found was that if I hold the USB to one side either left or right, this allowed me to help a boot farther into it sequence at first to just show the Samsung logo over and over then I could get it to get to the boot sequence about halfway through the boot animation until I finally got to the exhibit screen where displays its model and 4G status. I accomplish this by holding the USB to one side and pushing and holding the power button intermittently throughout the boot. Once I hit the unlock screen unlock the device and I immediately factory data reset it. I'm under the impression that mine was possibly I think that mine was somehow a corrupted bootloader or software still I don't know what caused it to backed up to this day occasionally it'll shut itself down and reboot on me that's why I'm here today I've got all the parts and pieces I need to flash a new rom and hopefully new software the new work over I'll be good to go I also cleaned the USB port made sure that it was still snug to the board all of the good stuff. I don't know if it'll help you but I had the same situation I thought you'd like to know that it was probably not what you were doing with the phone it may just be the software itself with this particular phone see I done nothing that you didn't had the exact same problems. I hope it was somewhat helpful if you haven't gotten it unlocked or re-booted yet. Then maybe just play around with the power sources and power buttons. And see if you can get the same results I did
Hi all
My girlfriend's sister got a Moto G 2014 this past Christmas.
It's unlocked, and I THINK she already got the 5.0 upgrade.
Yesterday she dropped the phone into me as "all of a sudden it stopped working"
The phone is bootloopin. The white Motorola powered by Android screen will come up, it buzzes, and restarts the phone.
The battery ran out by itself,but that made no difference.
Put the phone on the charger, pressed the power button after a while and same thing happened.
Only difference is that now every now and again it also shows the 0% empty battery screen.
Read around here somewhere about getting into the recovery and wiping the cache partition might solve this, but the button combinations I've seen online (pwr+up/dwn or pwr+up) don't seem to be working.
AND to make it worse, she obviously has no receipt for this.
So please... any ideas?
Charging for just a few minutes may not not be enough. You need to charge it for an hour or so then try to boot to recovery.
Charge it for 1-2hrs..then press power+voldown button together.. Hold it for 5 secs and release them together.. Now tell me whether the bootloader opens or not?

Unfortunately, as soon as the phone starts charging it turns itself on and goes into boot loop.
No buttons pressed or anything, as soon as it stars getting charge it's on!

While plugged in, you should be able to hold the power down until the screen goes black, it may take a few seconds.

Nope, no matter the duration of holding the button, it just keeps on bootlooping.
It's not even holding a charge as it starts bootlooping as soon as there's some juice in it.
Never seen anything like it!

Since it is booting or at least trying to, have you tried holding just the volume up or volume down by itself through one of those bootloops. I mean just keep holding the volume button without touching the power button. This is the major fault I can find with a non-removable battery. You can't easily remove the battery, which will fix some common problems.

Volume Up button doesn't stop bootloop.
Volume Down button DOES stop bootloop.
Afterwards:
Power button - Back to bootloop
Power button plus Volume Down button- Back to bootloop
Power button plus Volume Down buttonfor 5 seconds then release - Back to bootloop
No button pressing - Back to bootloop after 15/20 seconds by itself
