Hardware reboot when frozen? - Nexus 7 General

So my N7 froze tonight while trying to exit Snes9x...except I can't easily pull the battery to force it to reboot...
Is there a key/button combo to force it to reboot? I remember my Xoom had something like that. I've tried everything I can think of..
Of course right after I post it, I find it.
Power+ Vol+

Try holding power down.......and keep HOLDING. It will reboot

[Q] Help me turn my Captivate off!

So here is the situation:
My power button is non-functional. This happened before, and I was able to press very firmly on the power button to access a shut down menu and turn off the phone. From this, I was able to enter download mode (pressing volume button while inserting USB) and go back to stock, which surprisingly, fixed my power button. I thought this nightmare was over.
Now, my power button has stopped working again (ICS hacksung 5.0). No matter how much pressing, prodding, whatever, I cannot get the power button to turn off the phone.
I cannot find any adb commands to turn off phone.
"adb reboot download" simply restarts the phone, no download mode. (adb does recognize the device)
If I take out the battery, as soon as I put it in the phone boots up.
If I am pressing any of the volume buttons when I put the battery in, I can access recovery mode (But cannot select anything because power button is still broken)
Any ideas? I doubt my phone is still under warranty (1.4 years old) and I do not have mobile insurance.
Thanks for any help in advance
Depending on what recovery u have (cwm or ?), U can use the capacitive buttons, while in that revovery, to navigate and select the power off option.

Thats a neat tip that I didn't know about, but I can't find any option to power off? Sorry for being retarded but I have given this time I promise
cwm recovery is what I have installed atm
Reboot to CWM and Power off option may be at the bottom of the 1st screen that u come to. That is dependent on what version of cwm u have though.
Quick boot from the market, you can place a poweroff button directly on the home screen

The ICS ROMS CWM recovery doesn't have power off choice, so he can't do that.

Unfortunately the quick boot "power off" option simply froze my phone, or restarted it.
I let my battery drain so that I could get a dead phone (that part worked), but when I hold my volume buttons and plug in the USB for download mode it goes to the "battery" screen or (if both are held down) recovery. No download mode.
In recovery "key test" the power button fails to register any key press, but it is not spamming either. This seems like a hardware problem, but I am not sure how it was fixed when I flashed back to stock before if that is the case
I will next try making a download mode jig, I'll let you guys know how it goes...
My cousin had the exact same problem less than a month ago.
I see you tried reboot download through adb, have you tried it using the same command, but using android emulator from market? That worked for her phone so worth a shot.
its a far shot but odin is now available for use on the phone itself and works on our phones. maybe you can find a kernel thats had the buttons reconfigured. i know darky has one somewhere.

Thanks for this idea, when I use

#reboot download
the phone simply reboots. Same thing happens in "Quick Boot" 's "Bootloader" reboot option. This phone just seems broke as hell.
Firstly, this power button problem is a lot more common than you would think. It is most often a hardware failure - I mean the button mechanism (springs etc. just dies). Google it to see how common.
Your post suggests a clue: If just putting the battery in reboots the phone, then the power button may be stuck in the "in" position.....so it is always getting "pushed". Then anything you do would mean ht epower button is already being pressed. If this is the case, you will never get a software solution ???
Also, I absolutely do not mean to be nasty. But if you search both Q&A and General sections there are previous threads with this button problem. Many other solutions have been posted and it will be difficult to list them together.
Finally, you can actually replace - yes, replace - the button yourself. Google/you tube has it.

Discovered by accident: SAFE MODE

Hello all,
Maybe that will be a bit helpful, I've discovered SAFE MODE.
When I changed back shell in one of mine HTC Raiders, I left protecting tape on side buttons,
what means they were pushed-in all the time during powering up.
I was a bit surprised when watermark SAFE MODE came up in bottom left corner of my screen.
1. Pull battery out the phone.
2. Press power button and in the same time press and hold both volume buttons.
3. Hold both volume buttons down till you will see your home screen.
4. To exit SAFE MODE normally reboot phone.
I do not know what we can do in that mode yet.
But I think is hidden mode.
see screenshots.
Yeah I got this too on my att vivid I am confused as to what this actually is for
Edit: I am also on 4.0.3 ics

I've used Safe Mode on other Android devices to uninstall apps that were causing force close loops (you know, boot the device, app force closes, restarts, force closes, never letting you get past a force close box). All it does is boot the phone without launching third-party apps.

[Q] Have I permanently damaged my phone?

I just attempted to root my Galaxy Note using the instructions found on the development forum and I thought everything went well. Now, however, once the phone starts it wont turn on again - if I press the power button the screen back light comes on but thats it. I have to remove the battery to restart it, but then the same thing happens again. Any idea how to fix this?
Will it go into download mode if so flash a stock rom with odin

Power off your phone - take out your battery if necessary and wait about a minute, then put it back in.
Press volume up + home + power and hold, see if you can get into Recovery.
If you can, wipe cache, dalvik and do a factory reset.
Try to reboot.

I did all that and everything went through, same problem though after reboot - once the screen turns off, hitting the power button only makes the back light go on and the screen itself doesnt seem to turn on. The phone seems to function "as normal" - it even reboots fine - until I have to turn the screen on using the power button after initially booting it up.

If that's still the case, I'd try to boot into download mode and flash a stock rom (as was suggested above).

Help please Aroma is stuck and holding down power won't reboot the phone

I HATE Aroma installer. didn't touch the screen and install is hung.
holding down the power button until the capacative keys flash does nothing.
Any other key combo to force a reboot?
EDIT:
adb reboot does nothing either device not found
Power + VOL down for about 10 seconds.
nothing

Not holding it long enough then. That's "battery pull" button combination. It can literally take 10-20 seconds. The buttons flashing is a good sign.
EDIT: Timed it on my phone, exactly 15seconds.

You're holding both Power AND VOL down together, right? Not just power.

Huh, it's always worked without fail for me.
Congrats then, you get to wait until your battery dies.
try just holding power until screen goes off then volume down until in bootloader. may take a while but it works ive been in far worse situations with this phone but it always comes back. starting to think this phone is really hard to brick. all in one toolkit is a lifesaver if your not using it you should be. if you have a problem getting into recovery use it and if recovery starts then reboots or closes back to bootloader erase cache with all in one toolkit the boot to recovery
Define a while. Ive held the button down while lights flashed 200 times. It won't turn off.

where are you stuck at? download all in one toolkit and see if that has something that will help you. it saved me a bunch of times already. if the phone turns on or is on your okay. its just frustrating sometimes when you think you might have ruined a $600 device but as long as its on your ok no need to stress

just hold power+ volume down if it doesnt reboot after a minute let go and try again. or you could try all in one toolkit for your carrier to reboot to bootloader. trust me ive been stuck in aroma countless times there is a way
As I've said, adb and fast boot don't see the phone. I'm just going to have to wait for it to die.

If you've held the buttons for around 40 seconds you are going to just have to wait for the battery to die happened to another person. One other thing count the flashes after 20 release and then hold again and it should reset at 15 flashes if not then you are going to have to wait for the battery to die. Good news is after that the other person was able to get back to recovery and didn't have the problem again.
still nothing. Hope it drains down completely over night. I need to be able to get the thing up and running tomorrow
As an Evo owner I was shocked to hear the correct procedure for that phone was pwr + VOL UP AND VOL DOWN yes all three at the same time. I assumed vol up and vol down could not both be selected at the same time because they were on a rocker switch where, if one side is low, the other must be high. But it turns out you could do both. Is the HTC One like this?

back up and running. battery finally died. Flashed stock boot.img after a recharge and all is well.
I'm swearing off of aroma installers from here on out.
Had the same problem also today. But I did not give up to try pressing power + vol down. After several attempts the phone finally restarted.
You're more patient than me I guess. I worked at it for more than an hour and a half.

Just keep holding it, it takes a bit. The capacitive buttons will flash for a bit but keep holding it and it'll go dark eventually, then try try again. I think it took my six tries for trickdroid with full revovery wipes in between each one...

the capacitive buttons light up but still it doesn't turn off. I'm at the part where it says mounting partitions
I had this problem too. What you have to do is have the all in one toolkit and plug your phone to you computer. Then open the toolkit and press "reboot into recovery" it should reboot your phone back to recovery mode. Then proceed to installing your Rom. Remember to not use the touchscreen at ALL when using aroma or your phone will freeze up

aroma has a nasty issue right now where you can use the touch screen to make your selections for options and stuff, BUT sometimes(more often than not) the aroma app will freeze. even if you dont use the touch screen and use the vol/power buttons to make your selections it has more like a 15% to freeze. It has something to do with the way their database is setup i think. if all else fails and your phone freezes. hold down the power button for roughly 15 seconds. this simulates a battery pull. while holding down the power button you should see your back and home buttons flash. Once the flashing has stopped it means the phone should be off. at that point push the power button again for like .5 seconds and the phone should power on. if you want to get into the bootloader to access recovery hold down the vol down button while pushing the power button for the .5 seconds and it should load the bootloader and you can select to enter recovery.
someone else feels my pain. This happened to me Saturday. No matter what my phone wouldn't shut off and adb wouldn't work. I had to just let the battery die.

You have to try it every 20 seconds again and again, though its a tough process and you need to be patient

You need to hold the sensor in front of a very bright light source (did mine in front of a light bulb) and THEN hold the Power button for 15 seconds.
It will reboot. I can almost guarantee it. :good:
