So, a few days ago, I started having some problems with my stock Nexus 7 (not unlocked, no ROMs or anything like that). Some apps just wouldn't open, they would force close within a second of opening. Anyway, I think it might have stemmed from the game "Let's Golf 3", as problems started after playing that, and when going back in to it after a day of issues, a message appeared saying "Unfortunately, launcher has stopped" - it gave me the option to report or cancel, but whatever I pressed, the message popped back up. I pressed the sleep button, which seemed to turn my Nexus off somehow.
Then, when trying to to turn my Nexus back on, it just stays on the 'X' screen. I have done a factory wipe through the fastboot menu a few times, but it still stays stuck on the 'X' screen. To turn it off, I hold down the power button, but it just starts the process again automatically. The only way to actually turn the device off is through the fastboot menu.
I have seen talk of 'factory image' and drivers etc... but I am not too comfortable with that sort of thing. I know the basics of troubleshooting devices, but not much more. I am very wary of doing anything more than what the device provides me with.
Any idea how I can get my Nexus started, or am I going to have to look for a replacement?
If all else fails, then flash stock rom. If you're reluctant to do it the fastboot way, use toolkits. But it is very easy to flash a new stock rom. Go try it.

Is that not for rooted devices?
Flashing the factory image for my N7, how do I know which version my nexus is? i.e. 4.1.2 (JZO54K) or 4.2.1 (JOP40D)?

Use the one you like, just choose the right one for grouper -> nakasi (wifi only) or nakasig (with simcard)
4.2.1 is the latest Android version...

I too had the same problem. Tried everything. Finally gave it to ASUS service centre in Nehru Place. They will replace the mother board. May take 15 more days. So sad!
Okay, now the thing won't even turn on.
Holding the power button, and other combinations, nothing happens. No image comes up when charger is put in.
Feel like the thing is dead. Probably going to have to get it fixed or find a replacement. Don't want to spend too long without my Nexus

FYI,
The tablet can "play possum" when it is in APX mode. (Which is easily entered from a cold start condiition with Vol-Up+Power) By that, I mean the device is on, but absolutely nothing ever appears on the screen. The only way to detect this is to plug it into a computer and the unknown APX device (USB Hardware Id VID_0955&PID_7330 ) will show up.
The only way to exit that mode is to hold the power button down continuously for 15-18 seconds. [size=+1]IF[/size] that happens, pressing the Vol-Down button immediately after the Google logo appears will pop you into Fastboot mode.
But, given that you have prior experience with other odd happenings on the tablet, the above hypothesis is a long shot, I'm more inclined to say "It's dead, Jim".
If everything fails let it sit for 3 hours on the charger (as long as it is not overheating or something) and try a few more things one last time before you ship it out.

Yeah, cheers, I have it on charge now, and i'll give it one last go.
What is the best way to fix/replace it? I bought it from Argos - will they take it back (bought back in December)?

Call Asus first. Make sure to let them know it is less than 2 months old. If they want you to perform the return through the original retailer, they will tell you. But it's best to eliminate any other middlemen if that is possible, as I suppose that the tablet ultimately goes back to Asus anyway.
(Might be different through other channels, e.g. PlayStore - I dont know).
Hello all,
Recently I have had a major issue with my nexus 7. About a week 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 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. 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. But when I tried to restore the device yesterday, I was not able to access bootloader! I connected the device to my PC (running win8) and it is not recognized. Similarly, trying fastboot restart-bootloader gives me "waiting for device". I am afraid that the bootloader may have been corrupted somehow.
My question is, how can I fix this? Is there a way to reflash the bootloader, or is there something that I am missing? Is there a hardware operation that needs to be performed on the device (battery pull, etc)?
Thanks.
AW: [Q] Help! Nexus 7 not working, may be bricked
I doubt your nexus is bricked. Most likely you entered the APX mode. Hold down the power button for about 6-10 seconds, then it should exit from there.

When I hold down the power button, the device just turns off and comes back on again. The google boot logo shows for a few seconds, then I get a black screen.

If you get a Google logo, that is a good sign - it means the bootloader is at least partially intact, possibly even in perfect shape.
I would proceed assuming that your battery is completely discharged.
Put the device on the charger overnight and then try starting it up while it is still plugged in to the charger. Hold the vol-down button and the power button continuously until at least one second after the Google logo flashes - this should put the device into fastboot mode if the bootloader is intact.
Something to remember is that Li-Ion batteries have a safety feature that prevents them from charging if the battery voltage gets too low. This is part of the reason why they are shipped with a 50% charge - they can sit that way for months and months only self-discharging at a very very slow rate.
OTOH, if you discharge the battery deeply and then let it sit for a long time afterward - especially if there is something like APX mode draining current - the battery voltage can fall below this "safety threshold voltage" and (even though it is still a "good battery" it can no longer be charged).
I'm not sure it the N7 can be started up while plugged in to only the charger; if it can, disconnecting the battery and trying to power up the device might be a way to discriminate "dead device" from "unchargeable battery".
good luck
I've tried this before

I've tried this before. I still get a google screen, even after fully charging it. Does this mean that the battery has become unusable? How can I fix this?
Then try it again. It takes less time than typing a post into XDA.
There are two ways to try it.
1) Hold both Power & Vol-Down simultaneously, and keep holding them down until at least 4 seconds after the B&W "Google" text appears on the screen
2) Hold only the Power button down continuously, but be ready! Press the Vol-Down button as soon as the Google logo appears! - you only get less than a second to do this. (If you are late, the bootloader tries to boot the boot partition). Also, you need to keep holding the Power button down (3 or 4 seconds) after this - wait long enough that you are convinced that the fastboot screen is not going to occur.
As for the battery, you can pop off the back case and use a voltmeter to CAREFULLY measure the open-circuit voltage. The normal 0%-to-100% voltage range is about 3.6v - 4.15v. Obviously if it won't take a charge then there is a battery issue. BE CAREFUL - avoid doing anything which could short the terminals even momentarily.

I've tried holding down the buttons in various configurations at least 50 times already. As for the battery, there is current flowing, so I don't think this is a battery issue. Also worth noting is that if the device completely dies and I plug it in again, the charging battery sign appears (an empty battery slowly filling with white bars). Sometimes the device will give a black screen with little white sparks flickering randomly on it.
Well there have been several posts on here with identical symptoms, where the affected owner later reported that their tablet mysteriously started operating normally.
Unfortunately nothing consistent seems to have emerged from those reports.
You could try disconnecting the battery for a few minutes and reconnecting it to see if that makes any difference.
But whatever you do, you're gonna eventually have to press some buttons & the procedure I suggested is diagnostic for the bootloader, even if the boot or /system partition are borked.
BTW In my experience that battery charging graphic shows the charge state of the battery - does yours show closer to empty or full?

Mine shows the battery going from empty to full, like an animation. Also, I'm considering sending in the device for repair but I know that since the bootloader is unlocked it probably wouldn't be free.
Also can you link me to any posts related to this? They might be useful in solving my problem.
Thanks
Were you able to get your computer to recognized your Nexus when you connected it? I had to jump through a bunch of hoops with my Win8 machine to get the driver installed, because it didn't pass Microsoft's signature check. Maybe you can use Wug's toolkit to try to fix it, or at least re-lock the bootloader before sending it in for repair?

After spending a few hours, I was able to get an adb driver installed onto my computer, I also had to jump through a lot of hoops (I run win8 too). Running adb devices shows the nexus in recovery mode. However, I can't access the bootloader whatsoever. Typing fastboot reboot-bootloader just hangs, and I've tried several toolkits but they just hang. I'm not sure if I can do anything unless I can access bootloader. If you know anything I can do please tell.

By coincidence I was charging mine right now (82%), so I shut it down and looked at that battery animation. (I have the v4.18 bootloader & Dec '12 hardware) First the "lightning bolt" symbol shows up in the battery icon, and the a little later, it performs a "filling the battery up" animation. But here's the important part: when that animation runs on mine, it starts from nearly, but not quite full (mostly white, not all black)- about 82%.
Can't tell exactly from the way you described your situation, but this (again) sounds like your battery is either not charging, or the bq27541 charge controller is reporting the wrong battery state.
Unplug the battery and let it sit for a while before reconnecting. If you have a safe way to measure the battery voltage, do so. You'll know right away if the battery is charged and the charge controller chip is lying.

That is completely bizzare. The only way that a recovery can be started is via the bootloader. If the bootloader doesn't run, nothing can run. (The recovery is a booted kernel just as with the regular OS). Moreover, you saw the battery screen light up - if a recovery was (still) running, you would think something would show on the screen (although I guess recent versions of TWRP does screen blanking now). Very weird.

I really don't want to send it in for repairs if it's going to cost me. I'm a student with not much money to spare . One of the reasons I bought the nexus 7 in the first place.

I also fully charged the nexus 7 overnight. The battery icon now showed no animation because the battery was full (it first showed a picture of the lighting bolt battery, then a picture of a full battery) so I believe that the battery is working correctly.

I didn't make a record of them - you will need to search. What sounded very familiar was when you had said

What I recall - probably imperfectly - was that most of those cases seemed to spontaneously resolve when the owner charged their battery. And since your story started out with "black screen and little white sparks flickering", and "low battery" it sounded quite similar.
The various folks who mentioned this said things like "white lines flashing", "like sparks", or "like snow on an old-fashioned TV screen". Don't know if that will help you search, but they are in this forum (Q&A).
I also don't know if their tablets were in one particular mode or another (judging from a PC connected to the tablet - a black screen on the tab doesn't tell you anything) - I don't think any of them reported this.
As I said previously, that Black and White Google logo is produced by the bootloader. I just started my tablet in APX mode right now, and while the "charging battery" icon shows up when using the APX cold-start sequence (Vol-Up+Power), that B&W Google (text) Logo does not show up on the screen - the tablet goes directly from battery charging to APX mode (detected by looking at the PC - device shows up under "Other devices -> APX" in the device manager; VID/PID pair USB\VID_0955&PID_7330&REV_0103
)
So, my point is that it sure seems like your bootloader is there and capable of at least starting up at least part way.
What if your Vol-Down button was not working and you had a borked "boot" partition? If you had that combination, the bootloader wouldn't go into fastboot mode, as it would never see the Vol-Down keypress... and if your boot partition was borked, then you would never get any boot accompanied by a black screen.
At this point I think you should try observing the behavior of the USB port from the PC while trying to start it up... and even though you've tried it before, see if you can get the fastboot screen to appear. Perhaps there is something funky going on with your Vol-down button.
good luck

UPDATE!:
Not sure if this will help at all. But I ran adb -d reboot bootloader, and the device just turned off. Completely. I turned it on again by holding power for 15 seconds but I got the exact same thing as before (google with black screen following). Once the device was on and I connected it to Windows, windows said "Windows detected malfunctioning device". But I couldn't duplicate the results again. Running adb -d reboot bootloader just hangs.

Incredibly, extra-ordinarily bizzare. ADB on the tablet side is a daemon process that runs in userspace. You would need a completely functional kernel to be running on the tablet, and a functioning ramdisk too in order to communicate with the tablet. ADB does not talk to fastboot mode, nor any other mode of the bootloader.
IF YOU ARE REALLY SHUTTING YOUR DEVICE OFF AND THEN SOMETIME LATER YOU ARE ABLE TO TALK TO THE TABLET BY USING THE adb COMMAND (not fastboot), THAT MEANS THAT THE BOOTLOADER IS SUCCESSFULLY BOOTING SOME (unknown) LINUX KERNEL.
That truly beggars the question of why you are seeing anything on the screen after the google logo. Did the previous ROM not have a splash-screen?
Well, if you can communicate with ADB it might be appropriate to try:
adb reboot recovery
and see what this does.
If you can find the device in the Windows device manager, what would be really, really helpful would be the device VID/PID pair.
The way you do this is like this:
1) Identify the device in device manager; right-click on it and select "Properties"
2) Select the "Details" tab
3) In the "Property" Combo-box pulldown, select the Property Name"
Hardware Ids
If you can get those values we can identify exactly which mode the device is in. There is a decoder ring at the end of the first post in this thread
OK, I'm starting to get fatigued, as I offer up both things to attempt as well as avenues of exploration, and you seem to simply ignore all of it.
I know you have tried it several times, maybe even a million times. Please try both methods of starting the tablet to try and intercept the initial phase of the bootloader startup and see if you can get the tablet to go into fastboot mode.
It's OK to try it and fail. But in all this back-and-forth, not once have you said, "yes I tried it again and it still failed". Try it and report the result, even if it fails.
Please try it again - both methods. In the second method where you click the Vol-Down button only after you see the B&W "Google" text, you need to do it really quickly - and not let your finger off the Power button either for several seconds.

PS
The "-d" option to the adb command should only be needed if you were running an emulator via the Google SDK on the same PC.
If that were the case, when you ran the command
Code:
adb devices[/url]
you would see multiple lines of output indicating multiple devices on the machine - one for each running emulator, and one for the actual hardware device (so long as it is actually booted into a recovery or OS and you have the right drivers installed).

Please try it again - both methods. In the second method where you click the Vol-Down button only after you see the B&W "Google" text, you need to do it really quickly - and not let your finger off the Power button either for several seconds.

PS
The "-d" option to the adb command should only be needed if you were running an emulator via the Google SDK on the same PC.
If that were the case, when you ran the command
Code:
adb devices[/url]
you would see multiple lines of output indicating multiple devices on the machine - one for each running emulator, and one for the actual hardware device (so long as it is actually booted into a recovery or OS and you have the right drivers installed).[/QUOTE]
Sorry for not indicating the results of all of your suggestions.
Believe me, I have probably tried both of your button combinations at least two dozen times already. And I have gone down every avenue of exploration that you've suggested.
I've even tried every single one of the button combinations in the thread of nexus 7 button combinations. When I do anything from when the device is on, after 5 seconds or so the device turns off. Then the tablet shows the Google screen for about 5 seconds, no matter what I do. After the google screen comes a blank black screen (I can tell the device is still on because it's illuminated black, different from if the device was dead or powered off). There's not even a way I can get the tablet to power off - it just automatically restarts even if it's not connected to power, so I have to let it die or do a battery pull if I want to fix it. The black screen remains there indefinitely (until the battery runs out of course).
I've tried disconnecting the battery, leaving it disconnected for 30 minutes, connecting the device to power with the battery disconnected, having the buttons held down and connecting the tablet to wall power and USB pc, and different chargers. Nothing gives me a different result. The battery is alive and working, and the voltimeter did give me a current, sorry for not posting that earlier. About the random sparks/snow, there is really no pattern to when these appear, although they might be more frequent (but it might just be me) after a battery pull or full battery discharge.
Remember, I used to be able to access the bootloader but that stopped working for some reason. I'm kicking myself right now for not restoring the tablet when I was able to access bootloader, but I was busy at the time.
I've had some experience with rooting, locking, and unlocking other android devices, but this is something extremely weird.
Also, I should have posted the hardware ID's of the device before. I had done the exact same thing as you suggested when I was trying to install an adb driver for the nexus 7 (had to jump through a lot of hoops to get it working on win8, goddamn win8). The hardware ID's are USB\VID_18D1&PID_D001&REV_9999 and USB\Vid_18D1&PID_D001. According to the guide this means the device is in custom recovery, which makes sense because I was running Cyanogenmod 10 with clockworkmod recovery. If normally booting into the OS, the tablet should be giving me the default animated Cyanogenmod splash screen. Perhaps this issue is a bug with clockworkmod recovery?
I know that -d is to target a specific device, however I pulled up adb and went through each command methodically (really tedious) to see which ones would work. For some reason adb -d reboot-bootloader was the only thing that gave me a response, and even that won't do anything anymore (it just hangs, same with any other adb command). adb reboot recovery hangs also, and any fastboot command gives me waiting for device. Since I've installed a driver for it, in device manager the device shows up as Android phone and Android Composite ADB Interface. Windows tells me it's working properly (really? I'm not so sure windows).
I'd like to apologize for not indicating the results of trying your suggestions. Believe me, I have been trying them! I've spent probably a total of 12 hours trying to get this damn tablet fixed.
I'd also like to thank you. Without people like you this forum would not be any good. I am really grateful for any advice even if it does not work.
I know this is a hell of a problem. No goddamn clue how this happened. I love android but I sincerely hope that this is a clockworkmod recovery problem because otherwise that would make it a mistake on Google's (and therefore android's part). I know that the battery issues are quite frequent on android 4.2.2, but I have yet to find another user with my symptoms.
Lastly, do you know of some way to lock the device or destroy evidence of having the bootloader unlocked without being able to access the bootloader, in case this can't be fixed and I have to send it in for repair?

patil215,
Whew. That took you some time to write - thanks for all the details.
The USB\VID_18D1&PID_D001 USB Device Id sure does look like the custom recovery. I will assume - unless you say differently - that you would see this VID/PID pair any time you had the "black screen but with the backlight on".
Android uses this thing called the "BCB" (Boot Communications Block) to write instructions for the bootloader about what it should do when it starts up the next time. In the absence of seeing this, no doubt the bootloader has a default behavior. But basically, the way this works is that a "reboot" command eventually causes the kernel to write into this non-volatile memory area, and then a soft hardware reset occurs. The bootloader is aware of the BCB, and under normal circumstances, it will read it and attempt to follow the indicated boot mode - and then either erase the BCB or fill it with the "default booting instructions" just prior to booting a kernel or special-purpose mode previously indicated. In this way it will return to it's default behavior the next time it is booted.
The reason I mention it is that I have seen on other devices that got borked (HTC Droid Eris) in a way that sometimes those phones would always jump into a particular booting mode - and ignore any hard-button presses that would normally cause the bootloader to follow a different path. The Eris had/has "bootloader", "fastboot", and "OEM" modes and sometimes borked devices would not boot into anything other than the OEM mode.
So, since you apparently are seeing some evidence that a partially-functioning recovery is running, that sounds like a very similar scenario - the Asus bootloader is always booting to your (damaged?) recovery.
So, that's materially different (I think) than what other folks might have experienced it. The first time I've seen it here, although TBH I've only been looking in here for a little less than 3 months.
I don't know what else to suggest - it sounds like maybe you've tried things like "adb shell" commands?
If the bootloader can't be forced into fastboot mode, that (possibly damaged) recovery mode is the only privileged thing you have left. It seems to me that if you can't get into that somehow - adb being the most obvious route - then there is little left to do.
No, I don't know how to relock the bootloader without using the bootloader. That's probably something that can only be done with factory methods (possibly in APX mode).
Sorry.
Hi all
Apologies at coming on here and immediately asking for help, but....
I've had my Nexus 7 since July and have been very happy until NOW!
I seem to have been cursed with the dreaded flat battery resulting in n7 being stuck in the boot up.
I get as far as the Google and X icon but then stalls.
I've tried all the methods of long push of buttons/multiple buttons/etc but to no avail.
I can bring up the factory restore option so I know I can get it working again, but....
I have an exam in a week which foolishly had work stored for on my n7 without back up (yes fool) so....
Please is there anyway to retrieve my files via PC etc before factory resetting
All help genuinely appreciated
Mark
rooted vs unrooted (or unlocked bootloader even if not rooted) makes a huge difference in the answer.
Please state which.
Sorry about that
Not rooted.
It is absolute stock, nothing changed or added from purchase other than jellybean updates
Thanks Mark

Find someone with a Nexus 7, pop the back cover off and use their battery to boot up and retrieve your files. The back cover just pops off.

pleading mentions the battery, but then says "stalls" - not "shuts down", which is what you might expect if the battery was drained:

But, bigbop could be correct if pleading meant "low battery shutdown"
One other very long shot - assuming that that the device is hung - is to see if either adb or MTP are available. Normally that happens very late in the boot & I have to imagine that he has already tried that though.
Hi again guys
Firstly thanks for not giving up on my situation!
Bad explanation by me I guess....
The battery went flat/dead (my bad)
Plugged in to charge and screen lit up again but showing the 'powering off' script
Left over night on charge, wouldn't switch on again next morning
Left on charge all day still no joy but if I try switching on whilst plugged in I first get the Google name, then the Google X but then gets 'hung' (probably a better description than freezes etc as it still pulsates the colours)
Only way to get out of this is to keep power button pressed which switches n7 off and starts the cycle again
If during the recycle I keep the volume down pressed then it accesses the option screen to recover/reboot etc
Hope this helps, and again thanks (desperate to recover course work)
Mark
Hi again
Update...
Battery is showing full now
But still same 'hung' situation
Regarding the 'ADB'
I can get to the 'apply update from ADB' option
And if I choose it states.... 'now send the package you want to apply to the device with "adb sideload <filename>"'
As always thanks for any help or suggestions
Mark
Mark,
It sounds to me like what you are describing is ADB in the stock recovery, not a ADB when the regular operating system is running. (Is that right?)
Unfortunately, the stock recovery is only good for 2 things: applying an OTA update, and doing a factory reset. Even if your tablet needed an OTA update (and it probably doesn't if it is up to date), it probably wouldn't fix the looping/wedged phenomenon: usually that is caused by stuff in the userdata partition.
Doing the stock recovery factory reset might cure the wedged/looping problem - but only if it wipes all the data from your tablet. (Including the /sdcard area too).
The only hope I held out was if your tablet was reachable via a ADB or MTP with the wedged operating system sitting there looping. Usually those facilities start up quite late in the boot sequence, however so probably you don't have that.
Sorry. I think you are still SOL when it come to retrieving files.
Thanks for the help anyway
I'm guessing that with no further responses that really is the end for my work.
Unfortunately for me personally it will mean the end off my relationship with the N7, as much as I've loved it I really can't justify the obviously common occurrence of this happening.

Uhhh ... what?
The OP was about a tablet that you couldn't get into because
[a] it had a correctable soft-fault
you didn't want to exercise an available soft-fault recovery method because of a desire to reclaim user files not backed up
... and so far as we know the soft-fault recovery mechanism still is available to you.
How did that morph into "this is the end"?
You need to re-do your homework, perform a factory reset, and move on with your life.
You have used either software or hardware in the past haven't you? That thing isn't a toaster or a waffle-iron! No backups of important stuff? Come on!
OK, well then. Pack it up and send it to me with the charger and I'll pay for the shipping - UPS ground.
Doesn't the Nexus have a safe-boot mode?

Just tried right now - held the Vol-down button down continuously from about 2 secs after the Google B&W splash screen appeared until the lock screen appeared. That worked. (Stock 4.2.2)
"Safe mode" appears in the lower left corner. I had access to all the market apps (that I tried), but did not see a toast notification from StickMount after the boot - suggesting that safe mode only inhibits apps from starting on boot.
I suppose this could work (although the OP's deadline has probably come and gone) for bypassing a hung boot - but only if the hang is due to a market app that normally starts on boot.
TL;DR: Any way to fix/flash a Nexus 7 that reports it's in APX mode to Windows yet, that won't do anything else?
Backstory: I've had a 2012 Nexus 7 32gb since the day it came out (Oct 2012 or so?). Worked great for a year, loved it! Had AOKP on it, unlocked/rooted, used tons of apps, never a single problem. And then one day while I was using it to play music while charging it, out of the blue, it hard shut off while it was running, rebooted and shut off during boot and... never turned on again. Wouldn't indicate a charge, wouldn't turn on, couldn't get it to respond to any power or volume key presses, nothing.
I called Asus, and they agreed it needed to be repaired. I sent it to them, they sent me back the same unit, repaired, and said they swapped the mainboard out in the repair notes. Worked great, except the device was completely wiped, relocked, unrooted, and they removed my nice Stenheil screen protector.
I was without it long enough that I got used to not having it. Since it was completly back to stock, I decided instead that I would sell it when I found a good buyer (friend, etc), and buy the new 2013 Nexus 7 instead. I found a friend who wanted it a few days ago.
Today's Issue: I charged it over night last night so it was on a full charge this AM. I saw that I was still running 4.3 on it (hadn't really used it since I got it back in November), so I did the factory/official "OTA" update to 4.4.2 this AM. Went flawless, no issues, booted up fine. I updated all the apps on it, also worked fine.
I then decided to do a Factory Reset on it, (Thru Backup/Reset IN android, NOT Recovery). I went thru the confirmations/warnings, and then it said "Shutting Down..." and, it shut down. I let it sit for a few minutes, expecting it to boot back up (it never did). I tried to turn it on, nothing. I tried ALL combinations of power + volume, + charging cable in/out, etc. Everything possible, trust me, I scoured the web for new combinations and timing ,etc. No matter what, I never got ANYTHING on the display, no charging indicator, no recovery or bootloader, nothing. It's like the display is dead. The battery was fully charged this AM after being charged overnight so I know the battery wasn't even close to low. It's like it's completely dead no matter what I do.
I then tried to hook it up to my PC, which is setup for ADB etc, couldn't see it in ADB. In Device Manager though, it's showing as being in APX mode? So I tried holding power down for 10 seconds with it connected, and it DOES disconnect from windows, and a few seconds later, it shows up again, again in APX mode. Nothing ever appears on the display. Holding VOL down or all three buttons while plugging into PC never changes anything, no matter what, it ALWAYS shows in APX mode.
From what I'm reading online, this is a sign that the bootloader is missing or corrupt, and, that there isn't a fix for that unless you first backed up your crypto "blob" using Flatline (which I didn't even know about till today). I'm hoping that maybe what I've read is out of date? Is there perhaps a way to fix or flash this yet?
The whole thing makes little sense. All I did is update it, then reset it, all officially supported/normal things, on a bone stock tablet. It seems more like they didn't ACTUALLY fix it the first time it went back to them....
Help? AFAIK the tablet is now out of warranty. I just want to sell it and get the 2013 model! The tablet is in perfect shape, it's been used with a screen protector and case since day 1 - not a single scratch on the screen or case. :crying:
i'll take the silence to mean I'm screwed, right? :crying:
I don't know how, but it seems your bootloader is gone. (corrupted sector on the nand,maybe)
You can't do much without the proper blobs.
If I were you, would try to send it back to Asus. They are the only ones who can repair it.
Wow I can't believe it's been two months, but, I still have this tablet, still not working, Asus won't fix it for a reasonable price... anything changed on this in the last two months?
It seems like it should be possible to do something... maybe I'm just optimistic.
I want a 2013 Nexus 7 but it's hard to pull the trigger knowing my very lightly used gen1 model failed twice now.
There is no way to produce an universal blob and device specific blob creation is working so there is little to no reasons for further development.
You could fit a new motherboard 32gb ones are expensive but the 16gb are a lot cheaper
Programming is a race between engineers striving to build bigger and better idiot-proof programs, and the Universe trying to produce bigger and better idiots. So far, the Universe is winning.
They're readily available on eBay - $35 for a used 16GB motherboard, and $50 for a 32GB board. That's how I fixed my APX bricked N7...
Whoever stumbles across my late entry, if the N7 won't boot after empty battery, no button combinations work and PC shows only APX mode - take off the back housing (it's pretty easy to do) and disconnect and reconnect the battery cable, this let me boot it up immediately...
(my N7 however was plugged over night to charge before I attempted this unplug but actually didn't show up the charging indicator and wasn't bootable, surprisingly it was charged already half when I finally could boot it up)

I was sitting on my couch yesterday, and my nexus 10 froze up. This is pretty normal as it freezes up alot and i have to hold the power button down for 10 seconds and restart it. But it went to the bootloader screen and now its stuck in there. I have never rooted my device or have never even attempted to, my device has been stock since day 1. Pushing the RECOVERY MODE, RESTART BOOTLOADER, START buttons do nothing but restart the device into bootloader. I have searched up and down these forums for a solution and cannot find anything, everything thats related with this problem is because of a ROOT, once again i did not root or have ever attempted to root my device. please help. here is a youtube video with the problem. BTW my device is not recognized in windows either.
Edit: so i cant post a video cause im new on the sight. Im really stuck on what to do here.

So if you hold both volume buttons + power button, then select "Recovery Mode" with the power button, it just reboots back to that same exact bootloader screen? You don't see the Android laying on it's back with a red exclamation mark over him?

I was finally able to get it to a screen by holding the down volume + power that says "downloading do not turn off target nexus 10", but that still did nothing. Thats the only thing that it will let me do besides constantly rebooting to the same bootloader screen, no matter which option i choose.

That's the Samsung Download Mode, which is different from the bootloader. Could it be possible that your volume button may be stuck, and that's why it keeps bringing you back to the bootloader? I mean, you should at least be able to boot into Recovery Mode. If not, the only solution I can think of is unlocking the bootloader and flashing the factory image. Maybe your partitions got corrupted somehow?

I dont think the volume button is stuck, when i select recovery it just restarts and vibrates twice. When i power it off and start it it vibrates once, dont know if that helps. I also remember my battery being below 15% when it froze up. My device has froze up alot since the day i got it, is that normal? maybe it did destroy the partitions.

Hmm. Well, I can tell you I've never had a freeze up on mine. However, I did only buy mine a year ago, back in April of 2014. So I've pretty much only run KitKat on it before Lollipop now. Also not sure if they made any hardware revisions to get more reliability later in the device life cycle. I also pretty much only use it for media consumption like watching videos, so I'm not really doing any taxing processing tasks on it. It's weird that it vibrates twice when you try to boot into recovery. You mention your battery was low when it locked up. Have you left it charging while powered off for a while?

That sucks. I can empathize as I (and I'm sure plenty of others) know how it feels to get the runaround. Always frustrating. Well, I am thinking the only shot at possibly getting it working again is to unlock the bootloader and flash a factory image. Chances are always good that with a Nexus (barring any hardware issues), flashing a factory image will get it running again. That's why it's Nexus only for me, as Nexus devices are virtually unbrickable. Not sure if you have any experience with Fastboot and ADB. If not, I'm sure you can find some useful research tools on the interwebs and here on XDA. Once you understand it, here are a couple threads with some simplified installers: http://forum.xda-developers.com/showthread.php?t=2588979 and http://forum.xda-developers.com/showthread.php?t=2317790. Do keep in mind that UNLOCKING THE BOOTLOADER ERASES YOUR DATA, so you will lose everything on your N10. But at this point, it's all about getting it working again so you're not stuck with a $300 paperweight.

In my experience from what I've seen around these forums, they tend to cause more harm than good. It's good if you understand everything that's going on, and they can prove useful for devices that have really complex unlocking and rooting procedures, but Nexus devices are so easy to unlock and flash manually. I always flash each image file manually so if something goes wrong, I know exactly where it went wrong and how to fix it. The Google Play issue you mentioned is a perfect example. Flashing manually also helped me learn the basics of Fastboot and ADB. So if you want to stay on stock 5.1, I would recommend reflashing the factory image manually. I always use this thread to help me out in case I forget something: http://forum.xda-developers.com/nexus-6/general/guide-flash-factory-images-nexus-6shamu-t2954008. Although it's for the Nexus 6, it's the same procedure for the Nexus 5, Nexus 10, Nexus 7, etc. That's the real convenient thing about Nexus devices as well, as they are all pretty much flashed the same way. Should all be really simple since you already have the drivers set up from installing the toolkit. Good luck! And have fun with your newly revived N10.
