***TL;DR AT THE BOTTOM***
*^*EDIT 2!!*^*
Utilizing Cerberus, I was able to get passed the boot animation into the lock screen, though the Launcher is, for all intents and purposes, nonexistent. However, I was able to install Nova Launcher and can go to a home screen just fine. THIS IS NOT SATISFACTORY. I want to get back to STOCK Launcher, but it apparently does not exist anymore. I've managed to copy over my backup of Launcher2.apk, but it still refuses to acknowledge its existence. Can I get an update.zip that'll reinstall the default launcher from someone? I can boot into recovery via ROM Manager now I suppose!
+++EDIT!+++
+++~~~I have discovered that my problem is not the device being stuck in boot up, but that the boot animation will not cease--as +in the device is actually powered on, just displaying the boot animation like a screen saver. I cannot boot into recovery as I get +the Google splash screen and it never goes anywhere, my bootloader is freezing every time I plug it into my computer, and the +drivers will not install. My computer cannot detect fastboot and I can't connect to the Nexus via adb either. I CAN access internal +storage but that's about the extent of what I can do.+++~~~
Long version:
I decided I wanted to change the App Drawer icon from stock to a Nexus X that inverted its colours when pressed. I found the icon, converted it to png, inverted the colours and everything was going fine.
After a while I finally managed to find the right icons to replace in the system apk file "launcher2.apk". "ic_allapps.png" and "ic_allapps_pressed.png" or something very similar. I simply replaced them with my two icons, installed my modified launcher2.apk, and that was it.
Immediately, my home wouldn't open at all, no matter how many times I pressed the home button. It just would not exit the app I had up. So I started backing and ended up in an infinite back loop. I powered off the device, waited a minute, and powered it back on.
It came to the usual "Google" screen with the unlocked symbol at the bottom, no problems. However, then it started playing the boot animation. The boot animation never stopped. It looped infinitely. I tried resetting the tablet a few times for the same result. It was after 3 am and I had to get up for work in 4 and a half hours. I thought that maybe it was gonna take a while. So I flipped the Nexus over while it was "booting up" and went to sleep.
When I woke up and checked the tablet at 7:30, it was STILL booting up. Obviously I had screwed something up.
Now, stupid me, I had never flashed CWM recovery on my Nexus 7 (haven't had it that long), so all I'm stuck with is STOCK Recovery. I'm pretty sure I can rescue the Nexus by factory resetting it or something similar, but I'd rather try to save it first. All I modified was a LAUNCHER application, so I'm pretty sure the current state of the Nexus itself shouldn't be too far gone. Is there any way to save the Nexus WITHOUT a data wipe? And if the data wipe DOESN'T fix my problem, is it possible to somehow flash a stock ROM through stock Android Recovery?
***TL;DR***
I modified launcher2.apk and replaced "ic_allapps.png" and "ic_allapps_pressed.png" with two customized .png files (which I renamed to their appropriate file names). Now my Nexus is stuck on the boot animation indefinitely. I would like to save all of my data, as a data wipe would be inconvenient, but if I must do one I shall. I am on a stock ROM and a stock Recovery. If a data wipe/factory reset will not save my device, is it possible to flash a stock ROM through regular Android Recovery?
===Related but irrelevant to the problem===
Is it completely impossible to change the stock App Drawer icon to something different? I'd rather not have to get a different launcher app just to create a Nexus theme! I did a little more research and found that I should've modified the "all_apps_button_icon.xml" file as well, but I have NO idea how to do that.
Many thanks,
VonDerThWood.
As long as you can get into the bootloader you can flash back to stock using fastboot and the image from here

no need to flash back to stock, silly advice. just flash a custom recovery and flash a stock rooted rom. flashing a stock rooted rom will replace what you messed up on. dont wipe.

How can I reflash the ROM on stock Android recovery? Googling that returns CWM results.
He is suggesting you flash custom recovery with fastboot and just flash over top of what you did thru the custom recovery which you can do as well, what I suggested just returns it to factory state I don't see whats so silly about it I understand he wants to keep his data but worse comes to worse as long as you can get into the bootloader you're fine

youre right about if worse comes to worse. reflashing the factory image should be the very last thing to do, when all other options have been tried. im just trying to save his data
If you don't have fastboot set up you might want to give this post a look he describes how to get it set up.

I don't use custom recoveries and backup my data regularly with Titanium, so restoring after a reflash is really just an afterthought here, to each there own
The problem is not as it seems.
When I plug the Nexus into the computer when in Fastboot mode, it freezes the Recovery. I cannot select anything OR move the selection to anything else. The hell?
I noticed that when the Nexus attempts to boot up, the boot animation gets brighter.
__
Wait, when it attempted to boot up when plugged into my PC, AutoPlay recognized the device as Nexus 7. There is nothing on my screen but the boot animation, however I can browse internal storage.
I cannot, however, connect to it via adb apparently. ADB devices returns nothing.
____
Okay, the problem is NOWHERE near what I thought it was. The boot animation is replacing the lock screen/home screen/everything. I just received an email (I could tell because of the notification noise the tablet made). It is booting up, just not displaying anything passed the boot animation and ADB cannot detect the device. I KNOW it has USB Debugging mode activated and all, but what can I do now?

I usually make backups and nandroids but I've barely owned this device. ;P
Does fastboot detect the device?

Fastboot doesn't detect the device while booted up like this, and when I plugged it into the computer when in recovery/fastboot mode it not only froze the device, but fastboot wouldn't detect it.
I can get into the internal storage (just not the root of the device unfortunately). So what can one do when he cannot connect to the device via fastboot or adb, nor flash a custom recovery image because he can't access fastboot?
This is getting more complicated the more I dig into it. What the hell did I do?
Are you on the correct screen? I see how you are lumping Fastboot/recovery together, Fastboot is used on the screen with the android with his chest open after holding down the power/vol buttons from complete off , has version info/ unlock status in the lower left.. not sure if you can do that in the recovery but that is where I put the commands in
the freezing in the bootloader is a n7 bug. try a few times. try going into the bootloader then plugging in usb, and try plugging in via usb then going into the bootloader. try a few times, eventually you will get it.

You have to be in bootloader for fastboot to detect your device. Once in bootloader, open a command prompt where your fastboot.exe is stored and type "fastboot devices" without the quotes. If it detects it, it should list your N7's serial number.

Fastboot has the "Recovery mode" option but it just gives me the Google logo with the unlocked icon at the bottom indefinitely...which means I cannot access recovery either? Why didn't I notice this before? >_<

Tried 10 times by booting into bootloader first, then 10 times by plugging it in and booting into it while it's plugged in. This is a very...odd bug.

Nothing at all. Won't detect it or anything.
it is an odd bug. i think every n7 owner who likes to flash roms/kernels has had to deal with it at least once.

What about in device manager? Does it at least show an unknown device or something similar? Try reinstalling the drivers.

Click to expand...

Now that I think about it, it DID say something about failing to install an unknown driver the first time I plugged it in. Let me uninstall/reinstall the drivers.
____
After reinstalling the drivers (and removing both of the Nexus7 specific ones), I also removed one named "Android", which, coincidentally, is the driver that the tablet is trying to install upon being plugged in. I have tried to reinstall it several times, but it fails each time, AND I just reinstalled the real Nexus 7 drivers.
___
The Nexus drivers won't reinstall now. I even went to Asus's website and downloaded them, but I have no clue how to install it in this format.
Is there a way to open/install an app through JUST the Internal Storage? If so, I have the stock launcher2.apk file right here...I just need to reinstall it! Damn, how can I get to the Root folder without ADB?
Whoa! Stroke of GENIUS!
I have Cerberus installed on my tablet. Since I know the tablet is booting up, just not displaying passed the boot animation, I decided to give it a try.
I started an alarm, which forced the tablet to the lock screen...I can open apps through the Play Store (as I got an update notification) and the like, but I can NOT get to the home screen.
I opened Total Commander via Play Store, but I can't do anything with it. The app that I used was NinjaMorph and I'm pretty sure the only way I can correct my mistake is through that app. What do I do?
Found NinjaMorph in the Play Store, it couldn't fix my problem. Oh hell.
I tried to copy/replace the launcher2.apk file I screwed up with a backed up one but TotalCommander couldn't do it. It was even granted SuperUser permissions. Attempting with Root Explorer.
Success! I have copied the original Launcher2.apk back into the /system/app folder. HOWEVER, I can NOT install it.
Managed to connect via adb! Things are looking up! Now, how to install this stuff...?
When trying to reinstall the launcher2.apk, it gives me the following error:
INSTALL_FAILED_UID_CHANGED
So I tried uninstalling it to no avail. Troubling.
SO! Now what? I am into the device, and any app I have downloaded through the Play Store is available to me, but I cannot go to the home screen. I need to reinstall the original Launcher2.apk!
Retrying NinjaMorph. It supposedly installed my Launcher2.apk. However, I still cannot return to the Home screen. WTF.
I'm going to install a different Launcher. Hope that works!
Success. I can now return home to Nova Launcher. HOWEVER...
This is not satisfactory. I want my STOCK launcher. Anybody know how I can fix this? The stock launcher is acting like it doesn't exist anymore. Is there a way to just wipe THAT data and keep all the other data on my device?? (Though I admit, I do like how I already was able to change my App drawer icon to my Nexus X <3.)
Edit: I see you resolved it. Good job! I'll just leave this here... :good:

You sound to be in Windows driver hell. If you have access to a Linux machine or someone who does, this entire driver mess can be avoided.
You can't install an apk via the MTP or PTP usb interface. You have a few options to fix this, but all depends on getting your drivers sorted.
Otherwise, grab the latest Windows USB drivers from Google - https://dl-ssl.google.com/android/repository/usb_driver_r07-windows.zip and follow these instructions to install them - http://developer.android.com/tools/extras/oem-usb.html
With the drivers installed and the nexus 7 plugged in, try adb devices again. Assuming you can resolve the driver issue, run
Code:
adb install path\to\launcher2.apk

Hi
Tried to flash a new kernel and all seemed ok (flashed phones and nexus 7 few times now) when I came out of flashing I hit a bootloop, I though nothing of it and tried to restart....same issue, so next I tried to go into cw recovery, no joy, it will not show again.
I can power/vol keys to android fastboot screen with start power restart boot and so on but if I choose recovery nothing happens, I am stuck with either a bootloop or stuck on android fastboot screen and not able to move from either.
I have tried the toolkit and most other things but the problem is it cannot see my nexus 7, even after installing drivers and so on the toolkit (top right) does not list my nexus as found, because of this I cannot reflash any stock firmware/recover/reflash cwr.
Not sure how I can get around this if my pc cannot see the nexus 7.
Thanks for any help

I cannot flash anything. On the fastboot screen I can scroll up and down powr off/start/recovery....if I choose any (apart from power off) nothing happens.
When I hook it up to my pc it cannot see it, nexus 7 toolkit also cannot see it, it does not list it as found so I cannot flash anything on to it, if I try it just says waiting for device, tried other things and same thing either waiting for device or asks if fastboot installed.

You are already at the bootloader screen. Use your computer to fastboot flash a new kernel. Being able to get into recovery has nothing to do with it. You screwed it up flashing a kernel. Its likely thats all you need to fix it. Flash a new one with fastboot.

Hey man, how did you get your computer to recognize your device? Would be great to finally fix mine as this is the same exact problem -- computer doesn't recognize it even though in fastboot.

I don't understand exactly what you are trying to do, sorry: you said the pc does not see the nexus, "even thought in fastboot".. If you say even thought, it seems to me that you are able to access Android itself or maybe recovery? In that case I can't see the issue.. Sorry my fault, non english mother tongue
But, if have the device soft bricked and you are able to enter ONLY the bootloader (that is what we call often fastboot), then you should start to remove the not working fastboot drivers installed into your PC: launch the nexus in fastboot mode, go to Device Manager into your PC and search for a driver with an yellow exclamation point. This issue is very common so I hope that you have it, too.. So, uninstall that driver, then unlink the nexus from your PC; after a few seconds attach it to another USB port and see if Windows install a driver (it should). If this new driver doesn't work, too, or if Windows does no install any, try this one: http://forum.xda-developers.com/showthread.php?t=1426502
Hope it helps, let us know, see you!
EDIT: also, if you still have no luck, you should find a Linux or Mac PC/laptop and download the adb/fastboot binary files for that OS; this will definitively solve your driver issue ( @#ò#@!"@# Winzozz )

Hi sorry for not being clear. Basically I am only allowed to access the bootloader and my device is soft-bricked. I'm pretty sure I tried uninstalling and reinstalling the drivers about a year ago when I originally did it, but I'll try again and let you know. Thanks!
I apologize if this question has been answered already, but I just spent 15 minutes using the search button and could not find a response.
I just installed Matr1x v10.5 (http://forum.xda-developers.com/showthread.php?t=2007231) onto my Nexus 4 but it had JB 4.2. Based on the version notes of the thread, I assumed that it was backwards compatible with my phone and therefore installed the new version on my Nexus 4. Now every time I turn on my Nexus 4 the screen is blank. What can I do to fix this issue? Will it require a reset so that all my data is lost? Thanks.
What do you mean with '... The screen is blank'?
Can you get past the google bootanimation?

Go into recovery and flash the stock kernel. If that doesnt work you need to do a full wipe and reflash the rom.

Theoretically, if I flash v10.0 (which accommodates JB 4.2) it should fix the issue right?
I'm at a dilemma because I do not know if there are any other ways to insert the kernel into my phone as there is no microSD option on the Nexus 4. Does anyone know how I could potentially get the file into my phone?

I had already tried that, but once I connected my usb into my laptop I still couldn't transfer any files over.
In the end I reset my phone to factory settings, so the display still shows "Google". Just to confirm, the reason why this logo has been displayed on my phone for a while is because it is working to restore the factory setting (e.g. OS) correct?

I can't tell for sure since it never happend to me but I don't think if you choose to reset your phone to factory settings it will stay at the google logo.
If you choose to reset to facory settings I think you just will boot into recovery with that an android standing with something in his belly with a loading bar.
You can try this.
1.Boot into bootloader.
2A.Flash TWRP with the fastboot command and go to step 3.
2B.Flash stock N4 image with the fastboot command and profit!
3a.Try to mount storage and transfer another rom.
3b.Restore a backup.
Hopefully this works.

I have tried the above instructions up to step 3 because it did not work for me.
It shows the only files in my internal storage(/sdcard) are a file that says (Up A Level) and TWRP. Also, whenever I want to reboot it prompts "No OS Installed! Are you sure you wish to reboot?" At this point I am only interested in a factory reset now so that I can reinstall the initial JB 4.0 that came with the Nexus 4 and then upgrade to JB 4.3. However, whenever I do factory reset via recovery mode, I am stuck with an empty phone with the files I mentioned above.
What can I do to fix the situation? Thanks.

I think the reason that a factory reset won't help since there is no OS on the phone so it cannot reset something that isn't there.
And with the steps I mentioned, can you get into bootloader or does it directly boot into recovery.
Another thing you can try(I don't think it will work but I never tried it so you never know)
Download this toolkit:

There is an option to flash to stock completly, that will maybe do the trick.
Good luck!

I can get into bootloader fine, it does not boot directly into recovery.
My Nexus 4 is already flashed with TWRP. I have installed the program from the link you provided, however, I have not used it to flash my phone again as one of the prerequisites to using the program is selecting which OS version I am using (at this point I am not using any) and want to prevent any further issues from occurring.
It seems like I can't really do anything with my phone unless I get a JB OS reinstalled, which is what I am currently struggling with. I am presently trying to find a way to copy the downloaded Nexus image files provided online into my internal storage so I can install them.

You just have to do the following :
A) flash a recovery via fastboot (fastboot flash recovery recovery.zip)
B) now go ahead and boot from your recovery, and push the rom of your choice, in case you don't have one already inside your sdcard (adb push ROM.zip /sdcard/ROM.zip)
C) flash your recently copied rom of choice to your phone. (if necessary, wipe data, cache and dalvik cache)

I just spent a couple of hours reading through the guides (and trying them out) which led me to several other guides. To be incredibly honest, I am completely confused as there is a plethora of new information thrown at me. I have to pose several questions before I continue:
1) When you say bootloader, are you referring to the fastboot bootloader screen that pops up after holding the volume down button and the power button? I just wanted to confirm this as I am starting to feel you are referring to something different after reading several guides.
2) Is the scenario 2 guide you posted basically a method to "sideload" the JB 4.3 into the storage of my Nexus 4 so I can install it via Recovery Mode?
I tried installing the drivers but I cannot seem to do it successfully as I do not even have a starting OS for my phone in the first place. I can not access a theoretical "Developer Mode" either from when I first rooted my phone.
So basically, I do not understand how I can get the direct downloads from Google (the JB 4.3 files) and get them into the internal storage of my Nexus 4 to install the OS.
Is there a simpler way to do this? If not, here is my current progress. At the moment I am stuck at this guide (http://forum.xda-developers.com/showpost.php?p=34552123&postcount=1) from the previous link you linked and am between C-D. I cannot get my laptop to recognize my device via fastboot devices in command prompt (D). To be honest, this is the second time I've seen this guide but could not get it working properly which is why I used the file provided at (http://forum.xda-developers.com/showthread.php?t=2015469) to root my Nexus 4.the OS[/B].

Yes, the bootloader is the one where you press vol down and the power button together, that's the place where you select to go to the recovery, use fastboot.
First thing you got to do is turn on your phone on the bootloader as mentioned above. Then, assuming you downloaded this: [NEXUS 4 TOOLKIT V2.0.0] from here http://forum.xda-developers.com/showthread.php?t=1995688, open up command prompt and go to this address with "cd C:\Google_Nexus_4_ToolKit" or where you decided to install your toolkit. On windows explorer, go there and rename fastboot-toolkit or whatever it is called to fastboot to make things simpler.
Type in cmd: fastboot devices to check if it recognizes your phone.
If it doesn't; then install these drivers (you should have your device already connected via USB to your computer): https://www.dropbox.com/s/a808emeelvxkwyc/usb_driver.rar
Go to Control Panel\Hardware and Sound > Device Manager. Your phone should appear with an exclamation mark somewhere, right click it and click on update driver:
-Click on browse my computer software
-Let me pick from a list of device drivers on my computer
-Have disk
-Browse for where you downloaded the drivers I linked you to then click ok.
-You should find within the next page something that says Android Bootloader Interface, double click it and finish the installation.
After that's done, then type in fastboot devices on cmd again, it should show up now.
Then, go to here and download TWRP 2.6.0.0 http://techerrata.com/file/twrp2/mako/openrecovery-twrp-2.6.0.0-mako.img , that will be your recovery. After you've downloaded move it to C:\Google_Nexus_4_ToolKit to make matters easier.
NOTE: IF YOUR BOOTLOADER IS LOCKED YOU WILL HAVE TO UNLOCK IT , this can be done by typing fastboot oem unlock on command prompt
Now, simply type in this command: fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img you will now have a recovery on your device.
With the volume keys, choose to boot from the recovery. TWRP will load, while its loading, rename adb-toolkit to adb to make things easier. When its done loading, type in adb devices to see if it recognizes your phone, if it doesn't use your drivers again but this time instead of choosing Android Bootloader Interface, pick the one that says ADB.
When that's done, and it recognizes your device with the adb devices command you can now proceed to "push" or "copy/move a ROM you've downloaded in your computer towards your phone".
Of course you have to download a ROM, like Paranoid Android for example: http://goo.im/devs/paranoidandroid/roms/mako/pa_mako-3.69-20130722.zip , along with its GApps: http://goo.im/devs/paranoidandroid/roms/gapps/pa_gapps-full-4.2-20130719-signed.zip
You might have to even update your radio and bootloader in the future too, but let's leave it at that for now.
After you are done downloading the ROM of your choice, then type in these commands (assuming ADB works)
adb push pa_mako-3.69-20130722.zip /sdcard/
adb push pa_gapps-full-4.2-20130719-signed.zip /sdcard/
Having moved these two files inside your phone, now its time to flash them.
1) Go to Wipe on TWRP and simply swipe to factory reset
2) Go back and click on Install, look for pa_mako-3.69-20130722.zip and then add pa_gapps-full-4.2-20130719-signed.zip to the queue, swipe to install.
After that's done, simply reboot your phone and it should start booting up Paranoid Android and you're done. Might give you a few issues if you have an old radio and bootloader, but that can be fixed by flashing the new versions of these two in TWRP. Can be found here: https://www.copy.com/s/JniBu/4.3 files (mako) (these can be pushed via ADB like before, or you can simply download them on your phone when its working)
Hope this helps, don't think I can be more detailed.

The first thing I'd like to do before reporting my progress report is to thank you and failly for taking the time to help me out. You both have contributed tremendously in trying to help me out with this, so I would like to thank you both for that.
1) I had installed the sdk program and changed the adb path (following this guide http://www.redmondpie.com/how-to-set-up-android-adb-and-fastboot-on-windows-tutorial/)
Following wammie's guide:
2) Booted into bootloader
3) Downloaded and installed NEXUS 4 TOOLKIT V2.0.0 (had used it before but it didn't work for me so I relied on a different program to root my phone). Renamed fastboot-toolkit to fastboot
4) Typed fastboot devices in in cmd, does not recognize phone
5) Uninstalled current usb drivers and installed usb drivers provided. The driver I chose to install for was titled "Android". The other ! mark was "Base System Device" which was something I had never seen before until today when I had reinstalled usb drivers
6) Typed fastboot devices in cmd again and still nothing has changed
I am unable to continue any further as fastboot does not recognize my phone when I have it under bootloader. I had downloaded all the files that were recommended in your post. I think the reason why I cannot access fastboot devices is because there is literally no OS running in my phone. I could be wrong though.
I guess I'll take a break and call it a night since I've been trying to fix this problem the past 13 hours or so. Any additional feedback and support is appreciated!
Additional Notes: I have tried this both on my laptops (Windows 8) and on my desktop PC (Windows 7)
Luckly, if windows doesn't recognize your device while in fastboot it isn't because you don't have a OS installes but because not correctly set up drivers.
I posted a link some posta ago about a toolkit:
http://forum.xda-developers.com/showthread.php?t=2015469
When opening the program at the top there is a button called full driver installation, press it and follow the instructions.

This is what you should do when you are updating the drivers, its imperative you get those drivers working. Otherwise, you won't get access to fastboot.
Oh I would recommend using a Windows 7 PC.
Windows 8 can also do the trick but you maybe need to disable driver signature enforcement, so you better go with windows 7 for now.

Status Update:
I had spent a whole day reformatting my Windows 7 machine and am back at it. I have made a bit more progress than before.
1) After typing in fastboot flash recovery openrecovery-twrp-2.6.0.0-mako.img in command prompt, under the "List of devices attached" it is blank (i.e. there is no device attached). http://i.imgur.com/TnyBCKS.png
2) I have successfully installed the usb driver on my PC the first time when the only explanation mark was titled "Android", however the only Android option at the moment now is labelled "Android Bootloader Interface". No such thing as ADB (or any variations including Android ADB Interface) exists.
3) In TWRP Recovery mode, I see an exclamation mark titled mako but I believe that is irrelevant. I have tried installing the drivers to this just in case but failed. I then tried it again in Bootloader mode and mako is gone and Android Device pops up again with "Android Bootloader Interface"
4) I have tried restarting my PC and repeating the above steps.
Edit:
5) The only time I see an Android Composite ADB Interfaces is when I boot normally to the "Google" screen. However, I cannot move any of my ROMS over into my phone. When I typed "adb devices" it shows a bunch of characters with offline beside it. I do not have any options to reinstall any drivers for this.
From my understanding,I should be able to access the Android Composite ADB Interface while in recovery mode, which should let me transfer my ROMs over... but the issue is I cannot access Android Composite ADB Interface while in recovery mode.
Also, is there any reason why I shouldn't use the official JB 4.3 img as the ROM I want to install on my phone?
I went to update to KitKat and it was nearly done and then the "No Command" error came up. My tablet has an unlocked boot loader but isn't rooted. However it was before but I updated it from an OTA and that got rid of it. I've tried booting into recovery etc but the same thing happens.
Anyone have any advice please?
Same exact issue and set up here. Also, maybe I'm just dumb, but I can't get my tablet to turn off either. It just keeps cycling back to the "no command" screen until I do something.

I think that both of you what you see (the "no command") is your stock recovery, if indeed you see an android with a yellow !.
If it is the case to access the menu of the stock recovery press power and tap volume up. The menu will give you the choice of rebooting your Nexus 7.

I can get to the menu but when trying the reboot option, it just cycles the same way again. Back to the android with a red ! and says "No command." I also tried clearing cache and data to no avail. I was going to try using ADB to manually push the update but my computer was recently updated and now I can't get the driver installed for some reason.
I spent too much time messing around with and learning how to do things with my SIII and not enough time with this
Same deal here! Not sure what to do short of wiping and losing my info.
Same here...any advice? Not sure what happened. OTA update too.

Wow, this seems to be widespread, at least somewhat. I'm in same situation. Toolkits, adb, nothing works. I thought this was a soft brick, but now I'm thinking it's toast. Probably doesn't help that I didn't have Dev options enabled along with USB Debugging. I can't even turn it off. Just bootloops after Google logo shows up twice, then to No Command error, then starts over again. I wonder what the hell is causing this. (Device was locked and unrooted)
Same boat here, even sideloaded the factory image via ADB.

If you have android-sdk-windows installed on your computer do not forget to update it through "SDK Manager.exe".
Pushing via ADB didn't work for me. That also failed.
I caved and called Google. Tech support is stumped as well.

I finally got mine working again!
I tried a million different things so I'm going to try and explain my process as simple as I can, I apologize in advance because I am far from an expert...
First, I tried using the method, well some of it, from this thread: http://forum.xda-developers.com/showthread.php?t=1907796
- I would suggest using this thread to get everything set up (drivers, ADB, the factory image downloaded and in the correct file location) I wasn't able to get the drivers working correctly with that route so I ended up using the toolkit to get them working but that thread helped me get all of the system files in the correct location and helped get all of the ADB stuff set up.
Once you have everything set up and your computer recognizes the tablet, (I checked that by opening a cmd prompt and using the command from the original thread above "adb devices"). As long as you see your device, I think you should be good.
From the "No Command" screen I held down Power and Volume + to get the menu to come up. I then chose the Restart option and immediately held Power and Volume -. This got me into the Fastboot Mode.
Once in Fastboot mode I went to the cmd prompt on my computer and used the following commands in this order from this post:
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system -w
fastboot flash system system.img
fastboot reboot
*Make sure that all of the image files are in the proper location on your computer otherwise this step is worthless
The tablet then rebooted normally and I was able to set everything up again. Again, I am by no means an expert at all, this is just what worked for me. Try at your own risk.
I hope I covered all of the steps, I tried a million different things last night so they all kind of run together.
I ended up doing and it worked for me as well. Wiped everything though. How can I restore / reinstall my apps w/o needing to download them all again?
Two things: That guide says you must have USB Debugging enabled. Since my wife had this tablet, I did not have dev options enabled at all, including USB debug.
The other thing is that when I run the SDK Manager, nothing happens on my computer. I double click it or try Run as Admin, and a small CMD box flashes on my screen for a millesecond and disappears. That's all.
My wife's 2012 N7 is having this same problem. Unlocked bootloader, but I reflashed factory image and unrooted before giving it to her. She got the OTA last night, and now stuck at No Command.
I've subscribed to this thread, hoping that you guys will have it solved before I get home from work tonight! Would love to not have her lose all her data.
(I was kinda mad that she got the OTA last night and I haven't got it yet on my 2013 N7, but that's another gripe for another thread)

Unfortunately I'm not sure on the SDK manager part. As far as the USB Debugging, I'm 98% sure that I did not have it enabled either. I think I did at one point but after doing several OTA upgrades, I'm sure it got unchecked.

Worked for me! Thanks, I don't believe I had USB Debugging enabled either. Shame it wiped all my data though.
OK, got mine back up and running! I'll just leave what I did here in case anyone can benefit from it.
I first used Wug's Toolkit to download and install the RAW drivers. (Option #4, I believe) They were the only ones that worked for me. I followed the instructions to install them and then when it looped to the No Command screen, I held volume up and power. This got me to the menu, where I chose reboot. I then immediately held down the volume button and power to get into the bootloader screen, where it (thankfully) stopped looping. Then I unlocked the bootloader using the one-click option. Next step was to download and flash factory 4.4 image using the Soft Brick mode. Fastboot recognized my device and pushed the image. Now all is well. Close call... I've already enabled USB Debugging for my wife on this tablet so that crap doesn't happen again. She did lose all her data but she is happy to have a working tablet again instead of a $200 beer coaster.

Hello,
I wanted to install aosp_grouper on my Nexus /, but after wiping the connection becam elabile during dlahing. Now I cannot connect the Nexus anymore to my PC via the Nexus root toolkit. The device shows only the Google logo and an open lock. Hard reset does not result in anything different.
Is there a way to reconnect to my PC or do I have to throw away the device?
Many thanks for your help.

Hi, Phero100...
Your device should be recoverable, because...

This indicates that the bootloader is still good, and the device is not hardbricked.
I've never used a toolkit myself, preferring to use fastboot commands instead, so I can't comment too much on the Nexus root toolkit you mention in your post. But it's possible you may get a response from the toolkit by booting your Nexus 7 into fastboot mode, as follows...
From a powered off state, press VOL-DOWN and then simultaneously press POWER-ON. Hold both buttons for 15 seconds or until the device boots into the bootloader.
If you don't get anywhere with the toolkit you're using, I suggest you just reflash the Nexus 7 back to Google factory stock using fastboot.
Take a look at my response to another XDA member, from a couple of days ago, where I elaborate on fastboot flashing in more detail...
https://forum.xda-developers.com/showpost.php?p=80387547&postcount=2
...and of course there are other detailed guides elsewhere on XDA.
Good luck

Dear Ged,
thanks, but it does work only partially. Although I got a new image on the Nexus, an opened android man with Start at the top (fastboot mode?), neither the toolkit nor Windows 10 makes any connection to my Nexus. Anyway, without connection I can't do anything.
How can I connect to the Nexus 7 now?

Hi, Phero100...
It's possible your Nexus 7's USB port has failed/is failing, and I'm guessing you've already tried different USB cables/different USB ports on your PC.
But... I have some questions...

Where did you get this image from, and why is it on your Nexus 7? It should be on your Windows 10 box - unzipped, with the contents in the same folder as the fastboot and ADB executables, and these are likely to be found in your toolkit folder.

Yes - that is fastboot mode.

What happens when you run this command from your PC?

fastboot devices
Do you see your N7's unique serial number confirming you have a valid fastboot connection - eg., something like this...

Have you read this guide...
https://forum.xda-developers.com/showthread.php?t=1907796
It's a little out of date, perhaps - but the underlying principles are still good. There are also other guides available here on XDA, and if you take a look at my own posting history, you'll see I've written some fairly detailed responses to other XDA members regarding aspects of reflashing the Nexus 7, although you may have to go back to around 2012/2013/2014, since I no longer use my Nexus 7 and haven't done so for about five years.
------------------------------------
I could have written another detailed guide here, but it would feel like I'd be 'reinventing the wheel'. The Nexus 7 is now a little over seven years old, and everything that can be written about reflashing it, has been written about it...
...and writing yet another guide seems redundant and pointless, not to mention time consuming on my part.
I would advise you to read around the Nexus 7 forums/threads here on XDA and the 'stickies' - acquaint yourself with using fastboot and rely less on toolkits - I know that people use them, and I'm not wholly opposed to them, but they hide/mask the process of using things like fastboot and ADB, and the possible errors they occasionally throw. In short, using fastboot directly is a more transparent way of doing things, not to mention a more granular way of doing things - eg., such as flashing a specific partition - and you'll learn more about Android, and will likely have a better idea of what to do when things go wrong, as sooner or later, they inevitably will.
However, I digress...
Comimg back to your specific case. Your bootloader is still good, which is a good thing - it means your device is not hard-bricked. If you cannot, by any means whatsoever, achieve any kind of connection with your Windows 10 box, then, as I intimated at the beginning of this post, your Nexus 7's USB port may have failed/come-loose/become detached from the motherboard, or maybe there's a problem with the USB cable you're using.
Another possibility is, you may have a Windows driver problem, which is something I've never experienced myself, and is therefore something I wouldn't be able to immediately help you with, without me doing quite a bit of research first. But I've read that Windows driver problems are a notorious obstacle when it comes to things like fastboot and ADB, and by extension, with toolkits too - so called 'driver hell' (ie., possible Windows device driver conflicts), so I would suggest you Google around, and run some searches here on XDA pertaining to that particular problem.
I hope I've given you some useful pointers in the right direction, and I hope you get your Nexus 7 up and running again.
Good luck.
Rgrds,
Ged.

If it does turn out to be a Windows driver problem, in my experience the Universal Naked Drivers work the best.

Not yet, but i will do.
On the other hand, if I try the toolkit again, to unlock boatloader it tries several times, but says that it is a connectivity issue. It seems to me that it cannot be the USB port/cable, because otherwise it would not be detected by windows. Furthermor, USB connection worked before until the decribed error occurred. Therefore, I assume that it might be a driver problem.

I have no familiarity with that image file, having never used it myself. If, as you say, it's on your Nexus 7's internal storage, you may be able to flash it using TWRP custom recovery, assuming you have TWRP flashed to the recovery partition. If not, then this brings us back to your problem, because TWRP needs to be flashed with fastboot...
You can find the download links (and instructions) for the Nexus 7 TWRP .img files at this link...
https://twrp.me/asus/asusnexus72012wifi.html
There are two download mirror links at this website, one for Europe and the other for America. Select the one that works best for you.
To flash TWRP, your Nexus 7 should be booted into fastboot mode, and from your laptop/PC, type this command in...
Code:
fastboot flash recovery [name-of-twrp.img file]
I usually rename the rather lengthy TWRP .img file to something short, like twrp.img, so the fastboot command is much easier to type, and would look like this...
Code:
fastboot flash recovery twrp.img

You answered 'Yes' to this question, and you do see your Nexus 7's unique serial number ~ this means you have a valid and usable fastboot connection to your Windows 10 PC. Logically then, your toolkit should work, and fastboot flash commands certainly should.
With regard to unlocking the bootloader, you might want to try this...
Code:
fastboot oem unlock
You should see a confirmation request screen on your Nexus 7, like the screenshot below.

Dear Ged,
I know manage to get everything running until flashing. The error occurs again, but hti time I red it correctly. It says zip file is corrupt. That is surprising to me given the source I downloaded the file from. I will now try a different custom ram.
