***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

I managed to get ADB working (via adbWireless) after the above post I made, however I cannot get launcher2.apk to install. This time I got the "INSTALL_FAILED_DEXOPT" error instead of the "INSTALL_FAILED_UID_CHANGED" one.
i try rooting my N7 but wiped all data on in so i have no os and im stuck in the google screen and cant do anything. i tried anything that i understood on forums, my pc wont recognize it. nexus root kit doesnt seem to work cause it say adb device not found and fastboot cant find it either. so am stuck with a n7 with no os, have tried reinstalling the stock os image from google but i cant boot the tablet at all it just stays in that google screen.
so if anyone can help me atleast try to reinstall the stock os ......because i am a noob
You have to be in boot loader mode.

I did the same thing to my 7 the second day after I bought it. What you described is exactly what I had experienced. This is what I did to restore my 7. I kept holding the power button until it turned off. Afterwards, I charged it for a while cause the battery was low.Then I got the tablet to go into fastboot mode by holding volume down 1st and then the power button. After that, I flashed using the Nexus 7 toolkit. Upon flashing, download 4.1.2 firmware using the toolkit and flash that to your tablet. 4.2.1wouldn't work for me. That brought my 7 back to life in new stock form.
In conclusion, I re-rooted using the toolkit and flashed a custom 4.2.1 rom using TWRP recovery.
If you can get your 7 into fastboot and your computer still will not recognize your 7, reinstall the drivers to your computer. I used PDA drivers. That worked for me.
I hope this works for you.

I DID THE SAME THING
our devices are not "bricked", just screwed really bad...
did you manage to fix it?

I used the toolkit for mac and it unlocked me, but when it came to the next steps it said device not found and then told me to highlight recovery and press start, when I do I get the android with the red ! symbol.
Can someone help me?
That symbol is a security feature within the stock recovery, volume up and power to access the stock recovery.

I tried that it's not working I press up then power the phone reboots and the red ! symbol shows up...
I searched and saw hold power and press up when I see the red ! but it just reboots the phone...

For me also Stock recovery never worked. Just try to flash CWM or TWRP.
Btw, What toolkit did you use and how did you install the drivers. Please answer these, so that someone can help you better.(Or is it just the 'mac toolkit' ?)
My suggestion: PLZ DO NOT USE TOOLKIT. If you are stuck at some point while using the toolkit, then you'll not know what went wrong and how you can correct it. Do it manually. It is the most hassle-free method. Trust me.
I think that ADB will not work in stock recovery(may be you can boot normally into your phone and then try adb). The thing which you are looking for is 'fastboot'.
1) Restart ur phone (Power Button + Volume Down, i guess) and land in the bootloader and connect your phone to PC.
2) In CMD prompt(or Terminal), type 'fastboot devices'. If your device gets listed here, then fastboot is working and drivers are properly installed. If not, then drivers are not properly installed in your PC. You need both ADB and FASTBOOT drivers. Install them properly.
PS: For MAC, i think the command is slightly different. Something like './fastboot devices' . Please look for the same in this forum or just google it and find out.
3) Follow this guide for flashing CWM and Rooting.

I used the nexus 4 Mac rootkit I found in here.
It unlocked my phone fine. But when it came to installing a recovery and root it didn't.
Neither my adb or fastboot are working now before I unlocked and I messed around and they worked now nada ...
I went to YouTube saw my problem tried pressing volume up and power like in the video and it just gives me a black screen and either turns the phone off or reboots it normally...not sure if in supposed to hold power and let go of volume or vice versa.
I placed all the files on the storage I just need to access stock recovery which I strangely cannot now...
Tried framearoot and got nowhere.
Very frustrating

Just as I mentioned, i also had the same problem with stock recovery. So I simply flashed a Custom one(CWM, in my case)
Get the ADB and FASTBOOT working and that'll solve your recovery problem. Try fiddling with your drivers again. Not sure how to do that in MAC. If FASTBOOT is working, the you can boot into a Custom Recovery(you need not even flash it) and perform whatever you need to.
fastboot -c "lge.kcal=0|0|0|x" boot customrecovery.img
Again, look at the efrant's guide i referred above; i took this from there only.Remember to replace 'customrecovery.img', with the actual downloaded custom recovery image name.
Or you can try posting your problem with the toolkit, in mac toolkit's thread.
I have been youtubing everything and finally got to
Reboot system
apply update from adb
wipe data/factory reset
wipe cache partition.
I now can get adb working so I tried ./adb sideload cwm from my desktop and it is giving me signature verification failed. installation aborted.
What can I do to resolve this?
I searched xda and no one can solve this issue from the threads I've read.
I fixed it! Whooohoooo! Installed cwm and root ....now to install pa rom.

I had more or less the same issues. I had also performed a factory reset. Finally got it back last night using mskip toolkit,after numerous tries using both tool kits. I downloaded factory image to the toolkit through the options in the menu,then flashed it,answering yes to the format question at first. It kept getting stuck near the end sending. Tried about 5 times and changed USB cord to different ports,lei ally it went through,went from google logo to x to google logo back to x(I stayed patient at this point and did not assume boot loop) it finally booted into stock tablet.
I had already tried this and other methods before numerous times,and was moving on going to teach myself how to do it through command prompt, sdk,etc...
Tried the mskip toolkit one last time and it worked.
I have a Nexus 7 2012 (KOT49H, nakasi) which will only boot into fastboot, but not to Android.
I don't know what caused this - when it happened first I rebooted, and it worked again for another couple of days, then I got a "Google Play Services has stopped" message, so I tried to power off and reboot the tablet.... and it won't reboot!
At that time I was unaware that such a thing as USB debugging existed, so it's not been set... Indeed all I know about these problems now is what I've found out here... so sorry if I test your patience!
What I have done:-
I have tried a factory reset, with no effect.
Tried Wug's toolkit, which was unable to do anything (as USB debugging not set?)
(Windows 7 appears to have the drivers for this - it appears in Device Manager as Google Nexus 7 Bootloader interface)
Tried Skipsoft's Toolkit, which succeeded in unlocking the bootloader, and I have flashed images (downloaded from google) for Boot and System to the appropriate partitions... still nothing! Flashing the bootloader image failed ("An error occurred")
Is this Nexus destined for the dustbin? It is, of course, out of warranty :crying:
Apologies if I've done something daft, but I'm getting desperate...
Can anybody help?
Many thanks
hEY,
i got the same. I tried to install cm11 and i format sd card and happens that i formated the system too.
Now i can only to restart in revory "cwm v6.0.5.0" but cant start in download modus with Power+down (see only GOOGLE LOGO with open lock sign).
With wugs fresh i got the same with the f**** usb debugging enable thing, i cant get into nothing only in cwm.
I would be sooo happy to find a tool like (adb-tool) how i can put files again on my nexus 7.
thank you guys in advance!

If you have wugs, you already have the adb tool on your computer. Look in the wugs directory. However it sounds like your drivers are messed up. If that is the case nothing is going to work until you get that corrected.
