Recently I have had a major issue with my nexus 7. About 2 weeks ago, it died (ran out of battery) while I was using it. When I attempted to turn it on after charging it, I would get the screen that says google, with unlocked lock icon. The tablet would be frozen at this screen. I left it running until it died again. I was running the latest stable release of cyanogenmod 10 with clockworkmod recovery with no problems before when this happened.
By now I had realized that the nexus may have been bricked. I did some googling and found that this is an issue other users have been having when their battery died on android 4.2.2. I attempted to restore the nexus. At this time I was able to access bootloader on the device by holding down all of the buttons at the same time. I think I selected the recovery option. However, I decided not to restore the nexus, and wait until a time where I would be able to turn all of my attention to the problem, and powered the device off, it may have been in recovery mode at that time but I do not remember.
But now, I can't access the bootloader! When I reboot the device by holding down power, I see the google screen for about 4 seconds, then I get a black screen (I can tell the device is still on because the screen is an illuminated black screen). Black screen remains there indefinitely. Any button combo (voldown+power, volup+power, all 3, volup+voldown (this one doesn't do anything), hard reset combo, etc) doesn't do anything except reboot the device and give me the same behavior.
I connected it to my pc (running windows 8) and used the nexus root toolkit by wugfresh to install some drivers. I could install the first driver the toolkit told me to but not the second because the device wouldn't reboot into bootloader. In device manager I see "Galaxy Nexus ADB Driver", hardware ids are USB\VID_18D1&PID_D001&REV_9999 and USB\Vid_18D1&PID_D001, so that tells me custom recovery. Running "adb devices" tells me the device is in recovery mode, but I just see a black screen. Doing adb reboot bootloader or fastboot reboot bootloader hangs and gives waiting for device respectively. Similarly wug's toolkit hangs when trying to reboot the device into bootloader.
I've opened up the back and done a literal battery pull many times. Battery connector is in place after this. I also accidentally broke off one of those tiny copper tabs next to the battery, but that's not relevant to this problem and I believe is minor, broke that after I got this problem. After I do battery pull and plug back in, I either:
a) get a battery lightning icon in the center of the screen, which begins to fill up after a few moments. Rebooting device gets me back into google then black screen mentioned above
b) get a screen with static/snow on it. There is also a hissing/humming noise coming from the back of it. Rebooting gets me to google screen again. This screen also can appear rarely with no discernable pattern to when it appears.
c) same google screen followed by illuminated black screen.
I've left the device charged in, unplugged it, let battery die, and tried many combos of buttons, but can't get anything except the three screens stated above.
I know the saying "Nexus devices are almost impossible to brick" but if I can't access the bootloader and just get black screen then I don't know if I can fix this.
I've posted a thread similar to this one before, so if your username is bftb0 then you've seen this problem already. I'm trying to repost with more information to see if any other ideas are there. Other thread is http://forum.xda-developers.com/showthread.php?p=39522179#post39522179.
So these are my theories to what the problem is:
-corrupted bootloader
-bug/corrupted clockworkmod recovery
-bad battery/power/overheating
-corrupted memory
So how can I solve this?
I know there is NVFlash but there isn't a version for nexus 7. Almost all of the things I've found involve using bootloader. Any suggestions for things I haven't tried yet?
I have obtained an RMA from Asus but I don't want to send the device in because the bootloader is unlocked, so they would probably not cover this under warranty.
Does anybody know of a way to erase evidence of having a bootloader? Or a way to convince Asus to fix the device even with bootloader unlock? What's the price of the repair if not covered under warranty? I'm a poorish student with not much money, so I hope it's not that much and that's why I'm reluctant to pay for repairs.
Also I haven't done anything stupid like fastboot erase bootloader, in fact I hadn't connected the device to pc in a week.
I think this might be a bug with android 4.2. I love android and nexus, but if this is google's fault then I might be done with Android.
Thanks so much.
if it's still bricked i would be interested in buying it for the screen (even screen only,and you keep everything else) cause mine broke today!

Perhaps. I'll try to see if I can RMA it under warranty, probably wouldn't be covered though. I'll consider it.
Anyone else, have ideas for how to fix?
Had that problem before:
I had fixed it by opening the nexus 7 and unplugging the battery,
then I hooked it up to the charger(its screen turned on to a black one with the hissing speaker) and used the power button hard reset it,
The nexus 7 reset and gave me a really glitchy/teary black screen.
Then I unplugged it and replugged the battery and put the whole thing back together (mines tape-fixed BTW) and turned it on

Hi, can you access bootloader mode???
If you not your Nexus has its /boot partition broken or formatted. That is a "Super brick" is irreversible.
Good luck!

/boot is kernel. It has nothing to do with his problem. He can't access bootloader.

No chance to get a free repair out of Asus right? Know of any way to get them/trick them to repair it for free?
If no, what's the price they'll charge?
Hi stereo8.
/boot is not just the kernel, is the boot loader too, and if he can't boot on boot loader mode we have the problem.

Update:
I think my device may just be stuck in recovery. I think I may have accidentally hit the recover button when I was able to access the bootloader. I was running clockworkmod recovery 10. Perhaps it has been corrupted.
How do I get out of the recovery using adb?
Why do you have 2 threads open for this ?

I've already posted that I've tried that. The device just powers off and doesn't power on again. Turning it on with any combination of buttons puts me back in the google screen then black screen.

Ok, while the device is registered as "recovery" open a cmd and cd to your adb set up.
Try using the commands
Adb shell
#wipe data
This should wipe all user data from the tablet, maybe even the sdcard/internal memory as well. I am looking to see if you can use and to flash a bootloader for you, but it would carry heavy risks.

Unplug your device. Hold the power button until it turns off. Then hold volume up, volume down, and the power button. It should boot you into recovery.

I'm sure there are more ways to deal with this, but I personally would just flash a custom recovery from bootloader and re flash the rom. Probably the easiest way to go about it. Others may have a better idea.

The easiest way in my opinion:

- download factory image from Google
- flash the factory image (fastboot or adb)
I am wondering why synchronizing some files with dropbox is causing a boot loop ???

Had a very similar issue today
Nexus started rebooting in the middle of different apps 2-3 times last night.
charged it overnight, unplugged it and went to class.
Then progressed to rebooting after only 40 seconds after the lock screen loaded from the reboot
40 secs wasn't enough time to do anything in android so after much research this is how I fixed it:
- in the 40 secs that android worked I pressed and held the power button and powered it down to stop the boot loop.
- when it was finally shut down I pressed and held the power and vol dwn buttons til the recovery menu appeared.
- used the vol buttons to select recovery, then pressed power
- When the android with the red exclamation point (!) showed up I pressed power then vol up and released for the menu to appear.
- Selected and execute Factory Reset. Then wipe Cache. then reboot, fixed the problem so far, now I'm re-installing apps.
I talked with a google rep about the problem, said it could me anything from a poorly written app, to a corrupted boot sequence.
Anyone know what may have caused this, so I don't inadvertently cause it to happen again??

I had the exact same issue from your description, I solved it after I read someone else disconnected the battery. Its a pretty quick fix to what looks like an unrecoverable problem loop of switching on, then powering down.
Here's what I did:
Open the back using just my nail on one corner , it snaps off easy pesy, trust me
Use ifixit nexus 7 battery replacement guide , steps 1-6 only, note where they use a tool I used a pair of nail scissors to prise the connector out and back in
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
Pulling the battery out, as with any android device can work.
Total time 2 mins
It was working again before I put the back cover on.
Hey Guys,
I've been on android since the G1. I've troubleshooted all problems I've had since flashing cyanogenmod when he was first on xda. With this Nexus 7, however, I've kept it completely stock.
I've had it for a month and it's been great. Yesterday I downloaded a homeland torrent and watched it. Put it down, came back two hours later and it was on a black screen (it was charged when I left at least to 50% after d/l and watching the video). I pressed the power button and it wouldn't start. I finally held it down for about 30 seconds and then it went to the "Google" screen all in white letters. It stayed there. I tried holding power for 10, 20, 30, 40, 50, 60 seconds and it would just reboot to the google screen. I finally tried to enter fastboot, i was able to, and got excited at being at a functional screen that I went into "recovery" and then the google screen just popped back up. Now I can't even get into fastboot.
I've tried the nexus toolkits but they both need either abd in android or the fastboot screen. I can't get into them. I finally called google play devices support and they said they will email me within two days to replace my nexus 7. However, I'd like to get my stored images, music, videos, etc off of there at the very least (although, I'd much rather fix it and keep it).
Can you guys suggest anything?
tl;dr : Stuck on google screen, can't enter fastboot. Is there anything I can do to make it boot? Option 2: how can I at least take my (emulated /virtual) sd card data out of it?
THANKS!
You are rebooting each time you try fastboot, correct?

Wow, I see criticism every time someone mentions they're "Bricked." Now that someone finally is bricked--or at least it seems like--no one is saying anything...
What happens if you hold all 3 keys for ~30-40 seconds, it should, at that point, reboot to the bootloader.
If you are in fastboot again (if this would work one time) you can do
Code:
adb pull /sdcard
Because I guess when it's at the google screen
Code:
adb devices
won't give any output?
But I guess it's a hardware problem, otherwise it wouln't just have turned off...

ADB doesn't work in the bootloader.... ADB is Android Debug Bridge, and Android is not booted while in the bootloader.
Op, this seems like one of those weird things where you will just have to keep messing with it and it will hopefully work eventually. Mess with charging, different timing etc.

Yeah, holding all three, holding power and volume up, holding power and volume down doesn't work. I've tried holding power until it restarts and then doing power and volume down, up, and both. Nada.
I appreciate your input guys. I'll just return the product to google... hopefully they don't fix it without a full wipe and get ahold of my files! Yeek!

He said he was 100% stock.
The stock recovery doesn't start up the adbd daemon. That's typical for stock recoveries.
Proves the point that even if you stay with stock on the N7, you should unlock the bootloader as soon as you get the device. Then the option of soft-booting a different recovery (fastboot boot recovery.img) would be available for rescue situations - even if the ROM stays completely stock and unrooted.
Don't know exactly where you are......
If you OEM unlocked your device, rooted and flashed a custom recovery....I can assist.
Again going with the notion you did...
When your device is on and showing Google
Press and hold the Power key till the screen goes black
Once black, press and hold the volume down key
This will take you to fastboot
Press volume key up twice then power key to select
Device should now be in recovery mode
If you wiped the OS, use Wugs Toolkit to recover from soft brick in advanced options
If you want to push files to your device and try to recover, use MSKIP's Toolkit
Hope this helps....good luck

Posting on behalf of my daughter and if the topic has been covered I apologize and would welcome a link ... anyway here goes, no idea how the tablet got to it's current state but when switched on it will simply go through normal boot up up to the colored blocks then it goes blank and starts again. From what my daughter says she was having some issues with it in the morning and gave up trying to sort it and did a factory reset ... this appears to have gone belly up or at least done more than she expected ending in the current state. She did try and do the same again "many times"
To me it does not look to good but I have limited knowledge of Android so may be reading to much into what I see, any suggestions / assistance to get the system back to normal would be appreciated. The tablet is stock and was running latest version of Kit Kat
Thanks in advance
Was the tablet rooted? Have you ever used adb (android debugging bridge)? Try and get into recovery mode or fastboot mode from off you press power and vol up or down you will see either android on his back (fastboot) or recovery mode

OK well in fastboot type the command "fastboot OEM unlock" that will bring up a screen on the tablet warning you about the terrible woes of unlocking your bootloader go ahead and if that succeeds then you will see an unlocked padlock on the Google screen you bootloader is now unlocked if this process fails or hangs at the unlocking stage then you have a corrupted nand partition (bad) the internal memory of the tablet has become corrupted this is the source of your problems and a new motherboard is in order. If it succeeded then we are on to the next step download wugfresh nexus root toolkit use the unroot back to stock option be sure to tick soft bricked and this will automatically flash a new factory image onto the tablet

I am guessing it's bricked :crying:

It's possible you have a flat battery plug in the charger and hold power button for two mins use a watch it really does take that long if that doesn't work take the back off and disconnect the battery use a multi meter to check the voltage. Its a two cell 3.7v battery there are two pairs of red and black wires they should both give about 3.6/7v anything below 3.5 means its dead

OK once you have a shredded bootloader that's the end of the line. Unlocking the bootloader allows you to execute commands an reflash the tablet unfortunately it also opens up the possibility of hard bricking it if you do something wrong. Its recoverable but only if you have previously backed up the bootloader. No one has ever recovered a nexus bootloader without a backup and very few have ever done it with one.
On the bright side a new motherboard for a n7 is not expensive about £30 in the UK not sure about other countries. And is very easy to fit

Hi,
My brother is having trouble with his Nexus 4 and I was hoping I could get some help here.
The phone won't go past the boot animation, with the 4 floating balls.
It keeps showing that forever (left it for 20 minutes with charger, phone got really hot but did not get past the animation)
- Never rooted or changed firmware. Only updates from Google. (It was on 5.1.1/5.1/5.0.1)
- Sent to a shop, which claimed it can't be fixed (I do not know the reason they gave him).
My brother thinks it is because a weight was accidently dropped on the phone, but the problem only started 3 days after the incident.
No outer damage can be seen on the device, other then a small brake in the back glass.
Thanks in advance to anyone who will try to help
possibly?
Did you just update and it got stuck at the booting up????

Do you have data on it that you want to keep? If you don't you can try booting into the bootloader and unlock it. Then try flashing a factory image. This will wipe all the data on the phone though so that should probably be a last resort.

Do you have data on it that you want to keep? If you don't you can try booting into the bootloader and unlock it. Then try flashing a factory image. This will wipe all the data on the phone though so that should probably be a last resort.

I have no important data on it.
Which is the safest way to do this? I'd appreciate it if you would be detailed or refer me to a guide, as I want to be careful.
Where should I download the factory image from?
As the name of it states, I wish to get the one from Google, without any changes or addons from users.

First we should check if you can boot into the bootloader at all. First turn the device off. Then hold down both the volume buttons and then press and hold the power key. Keep holding all the buttons until you see some different colored text. If that happens we should be able to install a factory image, if it still gets stuck on the Google logo I unfortunately don't have any more ideas.
Tried pressing both volume keys and power button. Google logo show for a second, then black for 2 second, thank flashing red notification light every 1/2 second until I let go of the buttons.
When I release the buttons, the phone goes back to charging battery screen.
I see people suggesting that the red light flashing means a battery problem, but the device keeps trying to boot up while it is not plugged to the charger, unlike what happened to them
Any Ideas why this is happening or what the red light means in this case?
You need to press volume down+power button to get into bootloader. Unplug the charger before doing this.

Oh it was just volume down, not both. Heh, sorry.
Use the Nexus Root Toolkit (NRT), it's the easiest way to unlock, root, flash and manage your SuperUser needs!

Not sure, but maybe?
You can try using the nexus root kit & unlock your bootloader and see if a factory reset can work. If it does you can always relock it again ☺..Flashing a factory image can work too also ...
Tried volume down+ power button while unpluged from charger.
Google logo show up with vibration, then goes away after 2 seconds, like before, but then the screen goes blank. But red led not flashing.
What should I do now? Even just to use the Nexus Root Toolkit I have to allow Developer mode, which I can't as the phone will not boot up.

I'm you can't get into the bootloader then I am unfortunately not aware of any way to help you. If you can't even get into the bootloader I think it is a high probability that it is a hardware problem.
I understand. Thank you for your attempt to help me so far, I apriciate it
Anyone else has any Idea what I can try?

First you have to ensure "The Situation" of your phone, diagnostic is very important to decide the kind of medicine or treat. Your N4 booting, stuck on google-logo with red blink, then black screen.
To check : Connect your N4 to PC on linux check on terminal command $ lsusb if output
Bus 001 Device 005: ID 05c6:9008 Qualcomm, Inc. Gobi Wireless Modem (QDL mode),

there is a big hope to revive but very long journey. You are lucky since N4 is very popular device.You can obtain required file like MPRG8064.hex and friends

detected as Nexus 4 mean your device well alive. any respons from the phone if you check with adb command ? if the phone give respond to adb you can ask phone to turn to recovery $ adb reboot recovery ...

That sounds like the battery is completely empty. Put the device on charger over a night and try then to boot into the bootloader.
Once I had these symptoms (red light flashing) on my N4, it was enough to charge the battery for one hour. Then it booted properly. It's worth trying.

How do I do that?
The current state of my tablet is quite curious: Its stuck on Google logo and it will be this way until the battery completely drains.
What I've tried:
- Holding the Power button shuts it down for 1 second...then it boots right back up by itself.
- Recovery (POWER+VOL DOWN) doesnt work, it goes straight to Google screen.
- Connecting via USB to the computer, Windows doesnt recognize the device.
In fact, the only way I found to Turn the Tablet off is popping the back cover and unplugging the battery cable. I've left it unplugged at night, hoping it would clear some sort of Cache, didnt work. Also I've tried unplugging the battery cable, plugging it back and Turning it on with POWER+VOL DOWN in hopes of acessing recovery but it goes straight to Google screen.
Additional Info:
- This happened while I was trying to downgrade from 5.1 to 4.4.4.
- My device is the LTE version of N7 2012
- My device is currently rooted.
@RavenEffect hold down the power button for at least 20 seconds to turn it off, 1 second is not enough
How did you try to downgrade? Probably flashing went wrong? In worst cases the bootloader was erased during downgrade ... in that case ther will be no hope.

1 second is the ammount of time the tablet remains off, not the ammount of time i've pressed it. Yes, I've held it 20 seconds obviously.

Followed this guide right here: https://drive.google.com/file/d/0Bz6x7k-VkpUJU09paVM5cmh2Xzg/view
All the steps worked until the fastboot flash boot .\boot.img command. Sometimes it would get stuck on the command prompt and the tablet was frozen in Recovery Mode. I had to close the command Prompt, reboot the tablet into recovery again and Flashing another thing first, like recovery and system and THEN i would flash the boot.img.
So theres no hope?
First of all which factory image package did you use?

The one indicated on the guide, named razorg-mob30x-factory-10b7ca08.zip, the link is in the guide link also.
I suppose you have flashed the Nexus 7(2013) images onto your Nexus 7(2012) device ... that's not a good idea.

Oh Crap, really? Is there a fix?
Yup, same deal here, not done by me. Now I am stuck in APX mode and I need to somehow flash bootloader back into the tablet. Please, don't tell me there isn't any way to do this...

Have you tried flashing the images google gives on their website? (they also give a helpful guide)

Yeah, of course, but there is one problem. I can't boot into recovery mode, the bootloader got destroyed. So the only thing I have is either google logo with padlock on the bottom or nothing with APX mode. So no ADB, no FASTBOOT.

I know for mediatek, there is smartphoneflashtool, which flashes to the device when it's turned off. I don't know if there is an equivalent that you can use.
I don't think NRT does it, so you might be screwed.
There is nvflash ... but only if you have backed up *your* individual device images before you need them. So if your device is already bricked there is no chance ...

Problem is that, when you plug the Tablet to the PC via USB, it doesnt recognize the device, like I've stated on the original post, so I cant even get to a step where I can flash any sort of file.
Well, if I think about it, only the bootloader got destroyed. The image is free on google sites. I just have to put the bootloader image into the tablet so I can get to the bootloader and flash everything else with fastboot. There has to be way to do that. I mean if the "BIOS" (screen with google logo) got destroyed, that is bad, but it is just matter of damage on free to share universal loader. There has to be way...
