Broken power button, any way to boot? - Nexus 6 Q&A, Help & Troubleshooting

I just bought a Nexus 6 on Ebay for cheap. (famous last words, I know, but I'm a cheap bastard) Seller stated power button wasn't working, but could still use an app like volume 2 power to wake up the device. I got a project fi sim and everything works except the power button. It has been working great but I let the battery die last night, is there anyway to get the phone to boot without the power button? I tried an ADB reboot, but my computer doesn't even recognize that anything is plugged in when the power is off.
I actually bought another power/volume switch and installed it. It will work to power up the phone, but if I try and use it to turn the screen off, it gives me a prompt to turn off the phone and then about 5 seconds later it reboots. I decided that was worse than a completely broken switch, so I but the broken one back in. I'm going to buy one more switch to see if I get the same behavior. I was just wondering if anybody has seen this behavior before?

Research on here and via google shows no way to boot without a broken power button. See the response below! Good info to know.
Luckily, when I got home I tried my replacement power/volume switches again and I did not have the issue with the phone rebooting. I think maybe I had them wedged in too tight the first time I installed.

My power button is broken. There is a way to boot it, its a bit inconvenient but whatever it works for me. I didn't like the 6P so I am waiting for the new Nexus.
To power on:
-Hold volume button down + plug in usb cable connected to computer. You should boot into the bootloader.
-Run command:
Code:
fastboot continue
-You will immediately boot.
I then had to remap the power button to volume down so I could lock the screen and such.
To edit:
-Pull the file
Code:
adb pull /system/usr/keylayout/Generic.kl
-Change "VOLUME_DOWN" TO "POWER" in Generic.kl
-Push the file
Code:
adb push Generic.kl /system/usr/keylayout/Generic.kl
-Reboot
-????
-Profit your volume down button now acts as the power button. To change volume, press the volume up button and adjust volume with the slider in the volume panel.
While it appears your issue is fixed, I think this might be helpful to other users who may search for this answer!

Will that work with an unrooted Nexus 5 as well?
Thanks.

Probably, since it's a Nexus. But the answer is to try and see. Or ask in the N5 forum. Hard for us N6 users to test without a N5.

You need to install fastboot on your computer, and then open a terminal.
Fastboot is part of the Android development kit from Google, but it is probably easier to install a package like this one:

[Q] Problem booting into Recovery

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
Sent from my SAMSUNG-SGH-I897 using XDA App
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?

[Q] Broken power button / how to boot without

Hello everyone
I own a Samsung ACE S5830. Recently the power button stopped working -- which was annoying, but I could live with. I just wouldn't lock the phone manually.
But now, finally, the thing I feared has happened: I let the battery run down.
My question is, of course: Is there any way to boot the phone other than the power button? Perhaps over USB?
Should the phone show up in adb devices's list, even if it is off? Because it doesn't, but I may be doing something wrong.
I am out of warranty -- so I'll have to get the phone serviced. Is it worth it, or should I just buy a new device?
Thanks a lot for your help.
Sorry to reply to myself.
Just wanted to let you know I suceeded in booting the thing. I don't really know how -- just hitting random keys while removing and re-inserting the battery, connected to usb.
I am starting to wonder if perhaps the power button does at least partially work -- any way I could test it? Obviously it doesn't perform normally, that is, not locking, booting, holding to get the shutdown menu, etc.

Hey!
If you can enter to DOWNLOAD mode(hold together 3 buttons[HOME+POWER+VOL DOWN]), then its probably working.
CHEERS!
Maybe this will be the solution:
1. Hold Home button
2. Connect to usb (or charger) still holding Home button
3. When in recovery menu, unplug usb
4. Select reboot system now
5. Succes?

Locked up phone, holding power not rebooting

I am on CleanRom and flashed OMJ's mod pack. CleanRom for what ever reason listed that he removed the fast reboot option. When I flashed the mod pack this option was restored. Right after first boot, my wallpaper didn't load (using landscape wallpaper app) This has happened before and a quick reboot fixes it. Well, selected hot reboot instead of full reboot. Shell rebooted, boot animation ran, then stopped at the cleanrom logo. The phone will not boot, is not recognized as adb access and will not reboot from holding the power button. I eld the power button for about 5 minutes, the capacitive buttons flash but it never reboots. When connected to pc with windows 8 adb does not connect. I am using koush's universal adb driver and adb and fastboot normally function fine. When my phone is connected it shows ad "android phone" in device manager but drivers are not installed. Pointing it towards the universal driver folder does not work and searching automatically does not work either. I'm planning on letting the battery die then trying to boot again unless anyone has any better ideas?
never mind, manually installed the driver and got adb to connect and was able to reboot
Next time, Place the phone under a Bright light and hold the power button. Not kidding, it works and mentioned various places here on this forum. Question 17
I guess that trick is our replacement for the battery pull

Interesting. I'm gonna re-lock it up and try that! Just out of curiosity.
EDIT: huh, that actually made a difference. Just holding the power button and it wouldn't reboot, put it directly in front of a light bulb and held the power button and it rebooted.

Please help!

I really didn't know what to put on the title since this is a specific problem.
My Moto X decided to turn off (or so that's what I think) and now it doesn't respond to my volume or power buttons. Power button hasn't been working in a while so I had to use my volume buttons for wake and status bar tap to sleep.
Thing is that I had 70% battery so I plugged in my phone but it recognizes it (lsusb) so it must be on yet the buttons are unresponsive, (so is active display). I can't do any fastboot or adb. what can I do?

In case you haven't tried this yet --
With the phone connected to your USB cable do: sudo adb devices
If you get the phone's device ID back then try [sudo no longer needed at this point] : adb reboot bootloader
If this brings the phone up in bootloader mode then you can try using the buttons to go into Recovery and clear your cache or do a Factory Reset. But if the power button is truly dead -- not just hosed due to a corrupted cache, etc. -- then you may be out of luck for doing anything in Recovery.

N6 power button stopped working, now I can't turn phone on

My power button stopped working a couple days ago but I was still able to wake device with volume buttons. I was worried that if my phone were to shut off I wouldn't be able to turn it back on so I booted into bootloader and was going to try and flash "oem off-mode-charge 0" (which should then make the phone power on when plugged into charger).
At the time I couldn't detect the device using fastboot and as I was searching around on my computer the screen on the phone turned off (was in bootloader at the time). I'm not sure at this point if my phone was on and that both the power and volume buttons were not waking device or if the phone turned itself off.
I have tried the hold the volume down and plug the charger in trick to try and get back into bootloader but nothing happens. When I plug phone into my computer it takes about 20 seconds but I get the little windows ding that something has been connected but phone is still not responsive. I'm starting to think I'm a little screwed here but welcome any input.
You just looking to get the screen to light up so you can implement a way to use the device without the power button? You could try gravity screen or something but first things first...
If its not lighting up on plugin have you tried connecting to a computer and opening ADB and issuing the command adb devices followed with adb reboot. If you wanna go back to bootloader just adb reboot-bootloader. That will restart device so screen is back on and I would turn on the Ambient Display mode so when you pick it up the screen comes on or get a volume power button app or gravity screen app that turns on when you take it out of pocket. Thats all I can suggest and hope any of this helps.
With phone plugged into computer, nothing shows up when I check adb devices or fastboot devices. I guess I'm unsure on what state my phone is in. None of the buttons do anything and nothing happens when I plug my phone into my wall charger (no charge light or screen on). The only response I can get is when I plug the phone into my computer windows makes a noise.
Anyone know what happens when a powered off phone gets plugged into the computer? Does windows make the little noise indicating a device has been plugged in even with it off?
It does not make a noise if its off.. That much I know. Interesting though. Are you sure you have the correct drivers installed for your nexus phone if you are on windows. Go into hardware manager by right clicking on my computer and make sure that its reading it correctly in usb devices without a yellow triangle next to it.
I should have the correct drivers. I just went ahead and reinstalled them through the nexus toolkit. In device manager it says: unknown USB device (device descriptor request failed).
I checked adb devices before all this happened and it displayed correctly. I then rebooted into the bootloader but the fastboot devices command did not show anything. It was shortly after that that the screen turned off. Will the screen normally time out when in the bootloader? I'm wondering if my phone is still in the bootloader with the screen off and both power and volume buttons non functional.
Only thing I can think of is to wait for it to die, then volume down + plug in to pc and when bootloader screen appears issue command fastboot continue and it should boot up. Then get something to remap key or an app. If this all fails after it dies and you restart it assuming debugging wasnt on or its just reading phone as media device of sorts not allowing adb then you may have to get the power button assembly possibly and install it yourself or open the back case and hit the power contact under the button and see if you can get it on. Thats all the ideas I have.
I'd also suggest that after you reinstalled drivers make sure you did a reboot and then plug in the device and also try using a different USB port and or USB cord also as odd as that sounds Ive seen it work before. Im pretty tapped on ideas tho. Do you know if you had usb debugging enabled?

Ok, cool. I'll take a look.
Managed to get it back into the bootloader this morning. So I guess this is a PSA, if your screen times out while in the bootloader, the volume keys will not wake device so since my power button is broken I couldn't wake it. At that point, the phone is in a state where it cannot receive any fastboot commands, even though it is in bootloader with the screen off. What I had to do was wait overnight for the battery to drain and have the phone power itself off. At this point the volume down plus plug in charger trick worked to get it back into the bootloader with screen on. At that point I was able to 'fastboot reboot' back into system.
Thanks for the insight people

Driver issue.
Remove/uninstall the drivers from your PC when the phone is connected.
After that reinstall the adb/fastboot drivers.
N6 - Power mapped to VOL DOWN; turned off and can't get it back on
Hi all, I had to remap my power button - I mapped it to VOLUME DOWN. The other day I voluntarily powered down my N6 at a test center.....and haven't been able to get it to respond since. I do have a Pixel 2 XL on the way - but not that sure I'll want to keep it. The N6 is so sweet.
I've tried holding the volume buttons (POWER and VOLUME UP) for like a minute, but nothing. When I charge it, I see the battery symbol (full) but only for about 5 seconds.
ADB does not see any connected devices. Wug's NRT does not see any connected devices. I'm at a loss and afraid that I've lost my N6 and will have to use the Pixel 2 XL regardless what I think about it.
Any other ideas?

Wow - just got my N6 to boot using this little tip I found on Reddit - https://www.reddit.com/r/AndroidQue...ny_way_to_turn_on_phone_without_power_button/
I was holding down the Vol Up and Power buttons (which are both the Volume bar since I remapped my power to Vol Down), but I hit 'enter' on the 'fastboot continue' text in the CMD prompt just after I plugged in the USB and the battery icon came up. It booted into bootloader mode briefly first, then went into system reboot. Whew!
I think your button assembly is broken and I would replace it. You could try the work around in Broken power button, any way to boot? by altarity, post #3.
