Hi, nygfan760...
If you're getting some sort of response, then that's a good sign.
First, just LONG PRESS the POWER-BUTTON (for around 30 seconds); this will force power-down the device and reset it.
Try powering up from there.
-------
If that doesn't work...
...try to enter BOOTLOADER/FASTBOOT mode...
Press both Vol+/- buttons... and HOLD... whilst 'Holding'.., now press the POWER-BUTTON.
You should get the BOOTLOADER SCREEN... with UP and DOWN arrows, adjacent to the volume UP and DOWN keys... with the START option adjacent to the POWER-BUTTON.
Press the POWER-BUTTON... Hopefully you device will START...
Rrgrds,
Ged.
Hi, I also had similar problems with my Nexus 7. I was able to get in bootloader after multiple tries. Kind of randomly... didn't understand why. Unit would finally boot but turn off randomly again.
I gave a try and removed the back of the unit to take a look... I saw that the battery was nearly unplugged. I simply popped the connector in and voila! no more SOD, turning off, nothing.
So, the Nexus was probably turning itself off because there was randomly no more power comming from the battery. (and also could'nt charge it)
Here's a link on how to remove the back shell : http://www.ifixit.com/Teardown/Nexus+7+Teardown/9623/1
Look at Step 4.
None if it worked. Luckily I was still able to return it to office depot. Thanks for the suggestions!

What was the app, and where did you download it from?
And if you hooked your phone up to kies and it saw it....then the phone must be powered up. Remove the battery again, wait 10 minutes, then replace it.

From the silence I assume he realised he hadn't actually turned his phone off at all and sorted it out...or the app killed HIM as well.

Nope im not dead and im a she not a he.
Yes the phone has power but only shows a black screen.
Yes the battery has actually been out all night.
No Kies did not tell me anything i got a box up on my phone when it conected saying could not connect as application open.
The application was called Kids mode by zoodles.
They have sent me 2 ways to reset my phone one of which to hold down the volume button then press the power button which shows a menu choose clear storage using the volume button and the phone should be restored....it doesnt do any of that just turns on.
The other way is this
a) Install the Android SDK from a website they mentioned
b) Connect the phone to the computer with a USB cable
c) Type "adb uninstall com.zoodles.kidmode"
of which i am currently attempting to understand.
If you know any different then your help would be appreciated.
oh and the app itself i found on the android market on my phone
try getting into recovery by pressing vol up+home button+power and release when the S logo pops up
Thank you for that. It didnt work.
Have been defeated all this messing about so have taken in to have system rebooted.
I had the same almost and am still locked in the "Logo of Limbo" ( the big S) after 10 days and dealers trying this and that. Can't say it was an app that caused it, but it seems resetting SGS is a task and a half sometimes

Well, it's not pressing but holding:
Shut down the phone
Hold Vol-Up+Home and power
Release power when you see "Galaxy S, GT-i9000, Samsung" blinks
if this doesnt work, try Vol+Down instead of Up, and update the status here with what you see.
Hi there, have a specific problem, tried to google and search through the forum but no success.
I have stock ROM with 4.2.1 android, no root etc., I was browsing web via Firefox, opened 3 pages, battery cca 48% when suddenly everthing freezed, even home button and whole screen become unresponsive. I pressed the Power button for several seconds to turn it off and to restart it, however the screen is off all the time. I have tried to do hard reset, hold the power button for 30-180 seconds, hold all 3 hardware buttons for 30-180 seconds, hold just power and one volume button, connect to PC (always connects as Unknown device, not able to load any driver), tried all of this with and without power supply connected. After all this I am still not able to boot the device. Any idea?

unfortunately I am not able to flash it as my screen is still black, I do not see whether it is on or not, I am also not able to connect it to computer as it still pops up message that the device is unknow and I am not able to install any driver for it, nor automatically, nor google usb drivers... still getting unknown device message...
I'd just return it to Google and get a new one

Ouch ! That sounds like a broken device to me. I'd also RMA it.
Have you try plugging your tablet into your charger and check if your device is charging or not? (you'll see a battery status in the center of the screen) if so try to charge it for an hour or so and then after that try to press the ff.
while your tablet is off press and hold both vol. up and vol. down button then press and hold the power button. keep it press for at least 10 secs. and see if you can go/access your fastboot mode..
charged for more than 4 hours, tried that, did not helped, already sent for repair... hopefully will be changed for new one...
Just pry off the back and unplug the battery, ubereasy and will work fine again. Unless you got a lemon

Well, I finally bricked my first phone since starting with the Dream way back when.
I was flashing different boot animations on this D800 and came across one supposedly for T-Mobile. I had unlocked the phone, and changed from AT&T to TMO, so I thought it'd be appropriate. Boy was I wrong.
As soon as TWRP flashed that ZIP and rebooted, the screen went black. No LG logo. No animation, no sound, no nothing. So I looked into the ZIP file I downloaded (from somewhere on XDA, I'll have to find the thread) and it looks like a full TMO ROM. Great!
Now I can't even turn off the phone. I can see the backlight on the (black) screen, and when I press and hold power, it restarts after 10 seconds, but then comes back on. Something else strange is that a drive F: shows up on my PC, with about 70 MB of various files. Then there are about 10 other volumes, G: through T:, but they are empty.
Now what?

Yeah, I had just made a backup in TWRP, so my first thought was get back into recovery. However, Power+Vol Down doesn't do anything except reboot, just as it does when holding only the power button. Same thing with Power+Vol Up and holding all 3 buttons down.

You need to keep holding until the LG Logo comes back, then release and hold the buttons again :good:

Yeah, I have tried holding them down for multiple reboots but it's all black, every time. I haven't seen the LG logo come back up since I flashed that ROM. I've tried letting up on the Power+Vol Down button at various times to try to trigger it and I can't figure any way to get into recovery.

I assume you've tried shutting down completely first?
The multiple drives is good, you can resolve this. In not near my computer now but try looking for a thread about no recovery no download mode etc, in that thread it is suggested to connect phone with usb while running ubuntu.
I used that thread to revive my phone after a bad flash.
Keep in mind that the files mentioned there are maybe not for your model so you will have to find the correct files.

When I get a black screen after flashing a boot animation and the phone does not boot (just gives a black screen) I usually remove the boot animation via adb. This will use the generic Android boot animation and boot your phone up

Well, I don't think this was a boot animation, even though it was advertised as such. I wasn't thinking, because I know better than to accept a 798MB file as being just animation, no matter how elaborate. I mean, I've been doing this since 2008, but I flashed it anyway. Only after it blew up in my face did I look inside the ZIP and see all the stuff you'd have for a full-blown ROM. Ugh.
In any event, I don't have any adb shell or devices or anything when it boots, just those weird drives.
The real kicker is. this is my 2nd G2 -- the first one having gone into some kind of CPU thermal runaway. I had to send it to Samsung in TX and they replaced the system board. So I've "used" this phone, which I first bought December 5th, for only about 3 weeks total at this point.

I eventually figured out that I can get it to turn it off, by continuing to hold the power button, At first it will reboot, but after a few more seconds it turns it off. Or what looks like off -- nothing is ever drawn on the screen at this point, not even the LG logo. So I basically have to hold the phone up to my eye and watch for the backlight to be on or off.
I also left it "off" overnight, but it didn't help.

I just read your post saying that you had flashed an entire ROM. Do you have a ROM backup you can restore?
D803 up in this *****
Have you tried while it's powered off to turn it on and plugging in the usb cable(connected to pc of course) to see if it enters download mode(just incase I myself have never been able to access download mode using the button combination on the g2), if it enters download mode all you would need is the LG flash tool and a tot of the d800 to get back to stock?

Yeah, I was going to mention this. Once you have it completely powered down, hold volume up and plug it into your pc. That should throw you into download mode where you can restore through lg flashtool.
Alternatively, while powered down completely, you can attempt to boot into recovery by pressing and holding volume down and power, hopefully the lg logo will appear again, and you can release and press both again. I've been in situations where it took me a bit, meaning multiple tries and a few dirty pairs of underwear, to get it to work. But it eventually did. Admittedly, none of these instances occurred after flashing a rom for a different device, so your mileage may vary.
hi guys. today my galaxy s4 suddenly rebooted and now it cant get past the galaxy s4 screen on boot. it automaticly gets into this screen for several seconds, then a black screen and then again. also, when i put in the battery it automaticly starts, and gets in this loop.
i searched the forum a little and i suspect it is somthing with the home button. do i need to replace the whole display to fix thix? or what should i do.
And some important infomation, my home button is a little bent for the last 5 months, but so far it had no problems.
Have you tried to start recovery or download?
Remove the battery, wait half a minute, reinsert the battery and push at the same time Vol Up+Home+Power keys.
If that works you may wipe Cache and Dalvik Cache and maybe it will boot normally again.

I agree with @DeepankarS. Seems your power button is stuck.
If so it is a good reason to have the bootloop. Please double check it.

there is a huge difference mate in being okay and looking okay
Thus is not the first kinda problem..the download mode rebooting is directly liked to it..because the download mode will never reboot without the power button being pressed (exceptions ignored)
Try tapping it on a flat surface too...not hard..but ya..
Or search..how people released the stuck power buttons here..

So I was using my N7 as normal last night, starting up Kodi (Previously XBMC) to watch some shows before I went to bed, and as Kodi was starting, my tablet froze. I let it sit there for a good 10 minutes, nothing happened, so I proceeded to hold the power button down to force it to reboot, it turned off, and now it seems to be off forever..
It is showing up in my device manager as APX. I've tried all the tricks of holding down the power button + volume button to get into the bootloader, and it just won't give in. It is rooted, and it's been that way for a long time..
Is there maybe something that I missed in my research? It seems that there are two results; those who can hold down the power and volume and get into bootloader and go from there, and those who never revive the N7.
What are your thoughts?

Mine did this...Stuck at the Google Boot Logo and when I rebooted all i got was APX mode. Unfortunately for me the only way I got it fixed was to buy a Nexus 7 from Ebay with a broken screen for parts. Then I removed the motherboard from the broken one and replaced my bad motherboard with the good one. I tried everything before going this route.
Just an update:
I never was able to revive the old girl. Tried just about everything short of reflowing the board.
I found a logic board on ebay for pretty cheap and dropped it in, it works great and now I have more space! I used to have a 16, now it's a 32.
Also, I put Cyanogenmod on it, and I love it. Much more responsive than it used to be.
-Seth
Another update, she's still going strong, so it wasn't any other failures, only something on the motherboard.
