Major issue with my N7

Ok everyone I am having a major problem with my N7. This morning I noticed it was out of power so plugged i tin like normal, then I went to turn it on got the Google logo then it went to the Nexus logo. And it kept cycling through the nexus logo for hours and will not turn off. Whenever I try to turn it off it just restarts from the beginning. Now I didn't buy my tablet from the play store so I would have to go through Asus for a warranty replacement. Has this happened to anyone else in the past?
Some info. Stock, unrooted, locked bootloader, stock 4.2

Well this never happened to me before. Did you try removing the battery?

Well, to start, unplug your N7 from the power source and hold the power button down for about 15 seconds, this should force it off. From there, turn it back on and let us know what happens.

I don't see that you have tried holding down the power and the volume down. This should get you a hard reset.
Here is a short topic where a power and vol down worked for someone where a straight power down did not:
http://rootzwiki.com/topic/30101-reboot-tip/
it's the last post (#6)
Rather than trying to run the battery down, which is not all the way down when it shuts off and would take a long time to discharge just sitting there, you could pull the battery if you feel comfortable opening the case. It's not glued or anything and the battery has a ribbon connector.

So its in a boot loop? Reflash the image with Mskips toolkit option 9 after booting into fast boot mode. If that isn't the problem then do a warranty return. Not sure why you're stuck in a loop.

Phone not turning on and led flashing rapidly

I just flashed MOAR rom on my phone a few days ago and everything was working perfectly then while at work I pulled my phone out of my pocket and noticed my case had slipped off and was holding the power button down. After fixing the case I tried to unlock my phone and nothing came up on my screen. I held down the power button and the only thing that happened was my LED indicator is flashing green rapidly and at different brightness. Then I pulled the battery and left it out of my phone for 2 hours and still the only thing that is happening is the LED. When I plug it into my computer without me hitting the button the LED is flashing. It wont boot into recovery and I don't want to send it in and them find a custom rom on it so any help would be greatly appreciated.

I am assuming it won't go into download mode either? Try holding the power button in for at least 30-40 seconds.

No, I've tried holding just the power button for a minute or trying to go into either download or recovery mode and got nothing.

Try the same thing with the charger plugged in.
"Try holding down the power button for 1 minute with the charger connected. If this doesn't present the screen, try holding the power button AND both volume buttons at the same time. This should bring up a menu. There should be an option for reboot or force reboot"

Thanks for trying to help, I've tried holding both volume and power button for a minute and nothing. After having it plugged in for a few minutes my battery started to get warm.

Just something I found while looking for answers. At least your battery is getting warm. That is better than the alternative.

Are you using the original data cable? Try a different USB port maybe?

Please Help! LG G2 Won't Boot Up

I had rooted my dad's lg g2( D802) and installed twrp using an app named autorec as it was recommended by many people in the internet and had very high ratings and downloads in the play store. Everything was fine for a few weeks till I noticed that the app had an update. So I flashed twrp again from the app hoping it was a newer version and it said it completed the operation successfully. Then I just used the phone for sometime and after that I switched off the phone to enter the recovery. After it switched off, I pressed the button combination for entering the recovery but nothing came up. Then I attempted to just boot the phone and kept pressing the power button but nothing came up. I even kept pressing the button for upto a minute to hard reboot it in case it was just a case of hanging but nothing came up.After that, I plugged it in for charging and attempted to boot again. After I kept pressing the power button for about 30 seconds while charging, the led blinked red 8 times, paused and repeated itself as long as I kept holding the power button.
The problem is that it even the screen doesn't turn on.
I searched for this issue and saw that many others were facing this issue. I tried the following solutions given by them which did not work:
1) Holding the power button for a long time
2) Keeping it for charging until it's full but nothing comes up and the phone got heated up very much untill I stopped it a few hours later.
3) Removing the back cover and detaching the battery power cable from the phone after after waiting for sometime, reattaching it.
My dad showed it to the lg repair centre but they told him they need to replace the whole board which is very expensive, especially considering that it is a 2+ year old phone. My dad is very angry at me and probably won't let me touch his phones ever again if I don't fix this. Please help me.
Thanks in Advance
Edit: the charge was at 45% when I switched it off. Don't think it is because of low battery

With the phone pluggged into your computer, does the computer recognize the phone? And if yes, what does Device Manager report it as being?

more info... what variant? phone does not boot.. can you press vol up then plug phone .. does download mode works... stay calmed this can be fixed..:fingers-crossed:

I haven't tried plugging it to the computer. The way to enter download mode is holding the volume up button right? Thank you for the suggestion. I'm away for a few days but I'll tell my dad to do so. I'll post what happens then. Variant is D802

OK I told him to do that. When he pressed the volume up button and then plugged it to his computer, 13 new partitions showed up in windows, and it is telling him that he needs to format the positions to use it. But nothing is coming up on the phone

Do NOT let Windows format the partitions(!)
Use the SRKTool instead to unbrick from qhsusb_bulk mode:
http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
Afterwards use LG Flash Tool 2014 to flash the KDZ for your variant:
http://forum.xda-developers.com/showthread.php?t=2432476
It's better to let the battery charge to full first. Shut down the phone by holding PWR button for 10 seconds, then plug charger. It should work even in bulk mode.

Did you try these simple things...
shutdown phone keeping powerbutton down.
Start pressing power button & vol down....when you see LG logo for couple seconds. Release fingers and press vol UP and vol DOWN, same time. No power button.

But the problem is, even the screen doesn't turn on while on download mode. I'll surely try out the unbrick tool but will it work since normally, the download mode screen comes up. That thing is 760mb. I think it'll take some time for it to finish. (Ultra slow internet connection )

The lg logo doesn't come up when I do that. If fact, even the screen does not turn on

Thank you guys! Srk tools worked! Again thank you very much

phone won't boot/start up

I have a at&t S4 that all of a sudden today stopped working. When I restart the phone by taking the battery out and putting back in, it gets stuck on the Samsung Galaxy S4 logo and then a black screen. I tried going to recovery mode(volume up + home + power button), and it shows recovery booting in blue for a sec then goes black. I tried for download mode the warning comes up but after pressing volume up it goes black. I really don't know what to do at this point.

Tried using kies or smart switch to perform a firmware recovery?

Yes, the computer doesn't recognize that the phone is connected. It's as if when the phone goes to the black screen its actually powered off. The only time I get anything from the phone is when I pull the battery and reinsert it.

When the phone battery are too low, the phone could behave like that too.
Do you know that battery is fully charged or has more than 60%?
If not charge the phone first.
Plug the charger. If you did not see any sign showing that you phone is charging, press and hold the power button for 10 sec and release it. You should see the phone charging image.
Let me know whether your phone has enough battery power left but showing the above mentioned problems.

Yes, the battery is fully charged. I have another S4 Active that I've swapped the batteries with, along with a spare official Samsung battery and charger. It doesn't matter which battery I use, the phone acts the same with any of the 3.

If you have enough battery power left but the phone was behaved like that, you might need to flash the firmware.
Are you in lollipop or kitkat? For the time being, the only firmware available for kit-kat and lollipop is NB1 firmware cooked by muniz_ri . You can get it from here.
You mentioned that you can go to download mode but the phone shut off when you press volume up to go to the download mode after the warning.
Try the 10 sec method. Go to the download mode (power+home+volume-down) but keep holding the power button for 10 sec even though you see the warning message appear. Then you press volume up to go the download mode. Try this way and let me know.

It was on Kitkat. I can press the volume up and get it to show the download android screen but it immediately shuts off. Holding the power button for 10 secs. and then the volume up didn't do anything. The phone shuts off after 1-2 secs. of doing anything.

That is strange. The same thing happened to me. But I avoided the phone shut down by 10 sec methods.
Just hold the power+home+volume down for 10 sec, even though the warning sign show up, and then let it go all of them. Plug the phone to the computer and then press the volume-down to go into download mode. It works for me. Not on the first try though.
Try doing that with batter charger plug in too.

Thanks for your help. I figured out whats wrong, its got a faulty power button. I took the phone apart, put it back together, and was able to get it to boot completely. The slightest touch of the power button causes it to reboot though, so I'm going to need to replace it.

Glad you found the problem. I was trouble shooting for the software error.
Yes, power bottom could give you a problem too. I use screen off app so I do not have to use power button to turn off the screen.

Oh boy, a boot loop!

Get my shiny new phone, start it once, turn it off because I forgot to swap sim cards, and then it's just stuck at a screen that has a circle with a small "S" shape in it which I took to be the "charging" screen. Well ****. I force power-off the device and power it on again. "Installing updates" followed by "failed to mount /system" Huh. Cue an hour of frustration and not being able to find firmware and here we are. Advice? Please? Recovery menu does nothing to help and my next plan is to just flash stock firmware but apparently that doesn't exist (Sprint standard US fyi).
Update: I have no words. "Run graphic test" from the recovery options seems to have fixed the bootloop.
Update 2: the "fix" was only temporary. Nice. Back to the drawing board.

The easiest way is to return it to Samsung or your carrier.

Wow. That really sucks. :/

This thread is very old. But usually this issue stems from needing a factory reset. His inability to flash firmware is cause he was in recovery not download mode.
