Hey. Long time reader, first time poster. I've had Android devices for forever, never had a problem with flashing/installing ROMs, or anything else. That changed today.
My Nexus 7 (2012) had CyanogenMod 10.1 installed, and I decided I wanted to go back to stock. I used ClockWork's ROM Manager, found the highest rated N7 stock ROM, downloaded it, and started the install. I have TWRP installed. Installation was going fine, no errors or anything. I had it plugged up to the charger, left it alone, and went downstairs to eat breakfast. Twenty minutes later I come back, and it's still on the X boot animation. So I left it, came back thirty minutes later, still there. Assuming there was a problem, I tried to reboot into recovery to see what the deal is. I cannot seem to get into recovery mode no matter how hard I try. What can I do now?
TL;DR - N7 flash from CM 10.1 to stock; stuck on boot animation; can't get into recovery
Thanks!

Download the Android SDK and the latest Nexus 7 factory image, and then flash the image via fastboot.
Or, you can find a "back-to-stock toolkit" that will flash the factory image for you.
If you need further help with those tools, Google is your friend There's tons of documentation out there on how to flash Nexus devices back to stock.

Okay, I've searched and searched and no one seems to have the specific problem that I'm having with my phone, so I'm taking to the forums myself. I've been rooting since the G1, I know how to adb push things, I have used google and multiple forums to try to fix this problem. So here goes, anyone that can help I thank you in advance.
1-My phone, like some other MT4G users, reboots itself each time it's plugged in. Initially I thought this was because I was using a Kindle cord to plug it into the pc, so I bought an MT4G usb cable from tmobile, and still it boot loops (just the first white screen for maybe 4 seconds, then black then again and again). The only way to charge it is to let it start boot looping, take the battery out, turn it on, and if I'm lucky enough that it begins to boot up correctly I plug it in mid boot. If I wait til it's fulled loaded it just starts rebooting again.
2-It will not at all from any angle go into Recovery mode. If I try to go to recovery from Rom Manager, or from the screen you get when holding power and lower volume key or by flashing a rom through Rom Manager, it just boot loops just like mentioned above, until I pull the battery for a while (it is currently sitting next to me with the battery out) and then put it back in.
3-If by chance it's on, and plugged into the computer, it is not at all recognized. Ever. While it's booting up my computer finds something, but doesn't know what it is, and doesn't allow me to view any folders on the SD card. Yes I've installed the HTC drivers file. I've adb'ed things to this phone before, now it says device not found. I don't know when it stopped being recognized...
4-I've even tried to fastboot something over to it, but to no avail, still not found.
If I try to do a factory reset, it boot loops. If I sneeze it boot loops.... I don't know what to do, and if I trade it in under warranty, I have to reset it to stock rom, or they're going to charge me for a new phone. Any ideas!?
I have Cyanogen mod 7 on here.
have you tried a fastboot wipe? or have you tried to reboot to recovery from adb?
First, I don't trust using the actual ROM Manager app to do the flashing/installing.
Since you've been flashing since the G1 days why not use Clockwork Recovery? Just go into recovery and do the necessary wipes.
So I suggest to do a complete full wipe in Clockwork, meaning wipe data, cache, and dalvik cache. Install the newest CM nightly (Which is working wonderfully BTW) and see if your problems still persists.
Edit: I didn't realize you tried to enter recovery, oops. But yeah try what the buy above me said. Try re-installing the latest CWM recovery, if that still fails then try heading into there via ADB.

I second that, flashing ROMs from ROM Manager a terrible idea.
Well...if all else fails and if you are really thinking about returning it and still under warranty...few seconds in the microwave method should work just fine. They wont be able to see that its rooted if the phone wouldn't turn on, would they???
glimmer of hope...
So by the grace of god I did get it flashed back to unrooted, stock 2.2 by putting it as pd15img.zip on my sd card and going into bootloader. Once that was done I thought I would be out of the woods... I even plugged it in last night and no boot loop!! but this morning I unpllugged it (and I'm using a tmobile cable for the phone attached to my pc) and here it sits, next to me again with the battery out of it because everytime I try to turn it on (for over 40 minutes now) it boot loops to that stupid white screen (that is honestly driving me insane at this point). I know that it isn't rooted (because I dl'ed rom manager and it won't let me do anything without being rooted) so do we think that I'm safe to go to the store today to request a new one be sent? Thoughts? And thanks for the help thus far!
yeah I would send that back
Bad emmc chip? I'm sorry man, that's a terrible story.

Ok, I just started experiencing an issue. I suddenly can't get into recovery. Here is a little back history. My N7 was running CNA 3.6.6 (I know, but...), and I was bored so I decided to try ParanoidAndroid. Well, I have that gotta try something else feeling again, and when I try to get into recovery, it will go to the google screen, then go black for about 10 seconds, then go back to the Google screen and boot up. This happens if I reboot to recovery through the power menu, or getting into recovery from the bootloader. I even tried Quick Boot, in hopes it had some magic I didn't. No luck. The same crap. I even switched from TWRP to clockwork recoveries, and the same crap happens (I tried the same things I did originally).
Also tried through other apps too, like Rom Manager, Rom Toolbox, and TiBu. Everything works, but I am bored with this rom... I have tried turning it off, plugging the N7 into a PC and trying to get into recovery. Again, I can get into the bootloader, but as soon as I select recovery, it goes black, then fully reboots...
Anyone have any ideas? Any help would be greatly appreciated.
Have you tried re-flashing a recovery image, eg TWRP 2.3, from fastboot?

Scheiße, I reflashed TWRP in fastboot, and I am getting the same result. I think my N7 forgot it has a recovery!? I will try flashing clockwork through fastboot and see if this works. Thanks for your help...
Edit: Clockwork does not help. There is no recovery for me. I am now at a loss. Hopefully someone will have some suggestions...
Finally got my recovery back...damn latest bootloader!
Yeah, this has sucked. I have spent several hours figuring out what the hell went wrong. It turns out its the latest bootloader. Others are having this issue. So, I had to go back to stock (which will erase EVERYTHING) and then had to re-root. Now that my bootloader is back to JRO03D, I am back up and running.
So, the first time I did this route, I decided to take the update and re-root my N7, and ran into the same issue. I could not get into recovery. So, I had to do it all over, this time not taking the update and not updating the bootloaders, and I am now back and already have a ROM running and everything installed.
If you want to go this route, here are a couple of links that will help...
http://rootzwiki.com/topic/28544-guide-nexus-7-bootloadersrecoveriesrootback-to-stock/#entry764328 and go to the Back To Stock section. The next part is for rooting (if you wish to do this yourself)...

Unable to get into Recovery after 4.1.2 upgrade... - xda-developers
Any help?
Hello everyone,
I tried to root my 32g Nexus 7 with WugFresh's toolkit 1.6.1 (I'm fairly new to the rooting thing so I tried to use a toolkit). It did not go well. During the process I received messages from the toolkit saying it could not read Fastboot - but they seemed to go away after I switched USB ports. After the bootloader unlocked, I went back into the device and saw that it didn't fully wipe (I thought it was supposed to wipe out *everything*). When the rooting portion was finished, there were no new apps in my app page (super user and whatnot).
So I decided to nix the whole thing and just put it back into stock and try again tomorrow. I followed the instructions to get the drivers to where they needed to be, and then set it to flash back to stock and unroot the device.
First time around, it stalled during the flash. Rebooted, tried again, flash went fine. Toolkit said it would appear to be stuck in a bootloop for about 5-10 minutes. Well, after 20 minutes, it was still on that colorful "x". So, I reset it once again, and now it's stuck on the pretty colored "x". I do think the unlock is still there because the open padlock still shows up when I reboot. It just gets stuck on the "x".
Can anyone help me? I'd really rather not remove the battery if I have to (though it doesn't look that hard).
I feel terrible about this. This was my Christmas gift, and I feel like I've completely ruined the thing over what was supposed to be an easy root procedure.
EDIT: I was able to get to the Android with the red triangle on it and did a factory reset, but it seems that it still can't get past the "x".

The best thing to do is reflash using fastboot. Google "flash n7 with fastboot". It is really the best way to work on an n7, or any nexus device.

Oh wow, it worked!!! I used the .tgz file with the Toolkit and it came back!!! Thank you so much!!
Hi forum, this is my first time here. So I will try to keep it short and simple. I bought a mint Nexus 7. The previous owner had it rooted and it was on 4.1.2. I Saw the 4.2 update and tried installing the update over the air. When the device tried restarting, instead of going back to booting normal, it went into this thing called team win recovery project. I have noticed some stuff:
1. It says my device has on OS.
2. Its stuck there in my TWRP thing and I cant access my OS
2. my PC wasnt recognizing the device (I fixed that though by downloading the driver from Asus's website)
So long story short, I just want my device to be back to normal and unrooted. If its possible. Please if anyone can spare me there busy time, I would really appreciate it
Just read up on this thread. Best collection of all the proper information.

youve got a custom recovery, you cant install an ota. but you can manually flash a rooted stock rom if you want. twrp is a great custom recovery btw. you can boot up from its menu, or you can force reboot it by holding down the power button for about 20 seconds.
i have a nexus thats completely stock( out of the box) worked fine for about a month, let the tablet die and has been unplugged for about a week. got it charged up and and would not turn on. using the nexus root toolkit i was able to get to turn on. unlocked the device( unlock logo below google icon on startup) was unable to get past that point. now finally i can get past the nexus boot logo but it gets stuck on aindroid is upgrading " optimizing app 1 of 11" i cant root using the root tool kit bc when i unlocked device it got rid of developer options ( by what the msg said before i unlocked). im simply trying to get my device to turn back on. i dont plan to root or install a rom, im fine with the stock rom. i just want to damn device to turn back on. when i was able to power on the device when i first got it i did upgrade to the newest jelly bean rom. any one can help me on this issue ??
thanks
Boot into temporary custom recovery using Nexus root toolkit(Advance menu). Now wipe cash and devlock than try rebooting into system. If it doesn't work you can try factory reset. Last but not the least will be Flash Stock + Unroot(Soft brick/boot loop).
ok i wiped cache and devlock was able to to pass the nexus logo into what looks like another android is upgrading screen it got up to 14 of 20 and froze. between my 1st post and yours i was able to get android to fully run. did all the 1st time setup but after about a couple screen taps the device kept freezing and coming up with crash reports. there were a few times that the stock launcher even forced close. after a couple of restarts it finally quit again and would not even pass the nexus logo. ill try to do the other options that u stated in your post. any other thoughts ?

If the factory reset doesn't work just go for the Flash. I don't think you are much worried about the data so it's not a big deal for you. and I'm quit sure this is gonna work. Best of luck.
ok did that. went smooth but then once again it just gets stuck at the nexus logo. waited for over 10 mins like the notes say after re flashing and nothing. so i did a restart this time it passed the nexus logo, went to android is upgrading optimizing app and gets stuck at 4 of 11. being that this is pure android are there custom roms out there that i could try to flash via odin. ive rooted and installed roms before on my other android devices no problem but they were never pure google. am i missing something here. also what would cause a brand new nexus 7 just to go "ape ****" on its self.

Okay, that's weird!!!
Are you using Nexus Root Toolkit?? If yes are you using pre-downloaded android??
Try Automatically download + Extract.....
Last of all I'm really confused how there could be a problem when you got a fresh OS and Stock.
I agree with the messing thing that you told... Try checking and double checking everything... Check if you have selected the correct device or not.
And do a full wipe(including system) using TWRP before flashing again.
Edit: Make sure you are using the latest toolkit. You can get it from the link bellow.

I don't see a way how the problem still exists... :S
Whatever the problem is it's seems to be with android OS. But how it exists in completely new android. Sorry can't find a reason behind the problem. You can still try flashing any older android (like 4.1.2).
ok i got a zip of stock 4.1.2 and using the root tool kit i can install a zip via the twrp but it wont let me bc it says adb device not found and that developer options need to be turned on. im un able to turn it on bc i cant even get into the rom on the device.
thanks
ok i got it working. i was able to flash the older rom to my device and its working so far. no force closes yet.
thanks for everyone's help

I can't just think of anything else. Just telling you the things that I'd have done if I were you.
* reinstall boot
* change kernel
* turn off the auto update of android.
* try some costume room.
Don't throw it out the window you call always donate it to me if you really wanna throw it or make a drop test video...
Last of all just don't lose hope keep trying. you'll find out something surely and share it with us.
