Nexus 7 stuck in bootloop after attempts to reflash stock and unroot

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.

Nexus 10 stuck on boot screen after unlock or root

I've been trying to root 4 different Nexus 10s running 4.2.1 using the wugs toolkit. I was able to unlock the first Nexus10, but when I tried to root the device, it got stuck on the Jellybean "X" on the final boot up. After waiting about 20 minutes, I just decided to flash the stock. I then tried rooting it again and it actually worked this time. The problem is that when I try to unlock the next 3 Nexus10s, they will unlock, but then get stuck on the Jellybean X. I then tried the same process of flashing to stock and trying again, but it still doesn't seem to work. Is anyone else having this problem? Should I just try like a million times? Thanks.
try clearing the dalvik cache and data and reflash , it might work
I cant mount my device.I cant see my sdcard on computer or install(in TWRP).When I flash cwm touch.It told me can't mount sdcard.What the hell??? Now its already half bricked cant boot into android.:crying:
Boot up recovery, wipe everything except system and reboot, it should come up ok. For some reason both my N7 and N10 hung at 'X' during unlocking but that fixed them..

[Q] Need help. OS was wiped using TWRP v2.3.2.1

hello all. I really need some help. I let my friend play around with my nexus 7 and he got into the TWRP and accidentally wiped everything off my nexus including the OS so now when i boot it just hangs on the google splash screen. I can get into fastboot mode and the team win bootloader screen but thats it. When i connect to my computer it is not recognized so i cant drag and drop a new boot image. I would just like to have my nexus back to factory unrooted bone stock
Please help me out. I'm new to the android scene and freaked out that i have a bricked device.
Thanks in advance!

First of all, stay calm! :good:
If you are able to reach fastboot mode, nothing of value is lost (beside your personal data). You can just follow this guide.
At the end, your Nexus will be as fine as before. And don't forget to threaten your friend not to do such things again if he doesn't understand how to repair it.
P.S.: You don't have to unlock (flashing step 2) and re-lock (flashing step 5) your Nexus as you may have unlocked it before (according to information about installed TWRP). And be sure to use the nakasig/Tilapia image for flashing.

Thanks I'll try that guide out tonight after work.
How it happened was I received the OTA update for 4.2.2, but didn't update. So when I let him use the tablet he thought he was being nice by updating for me and when the nexus reset it kicked into TWRP which he thought he f*ucked up and decided to "wipe" what he did.

That's the reason why I don't let anyone (even my best friends) to do anything on my phone without me looking what they are doing ATM. You should have done the same.
All your data you've had on your phone/tablet is permanently gone, all you have to do now is to restore your os from a backup (if you have made backup before) or flash other ROM and you are good to go
For the future knowledge - if you can access any recovery mode it's almost impossible that your phone is bricked. If you can only enter fastboot there is like one percent chance of this that your phone / tablet is bricked.

You could flash a recovery with fastboot < fastboot flash recovery recovery.img > (just necessary if TWRP got wiped during the update) and then push a ROM with adb.
This method wouldn't delete your SD card.
How do you know that he just didn't wipe system? It's possible that he didn't, so all you may need to do is flash the system image. If you have driver issues while in fastboot, I recommend the official Asus drivers.

nexus 7 stuck on android is upgrading

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.

Try flash stock image throught toolkit.

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.

Not the exact same situation, but I found certain Wifi router's would trip my nexus into reboots until I rooted

[Q] Bootloop on everything but Stock 4.2, tried everything, looked everywhere (hope)

I am not new to ROMs and flashing etc., but I am completely stumped on this one. I have looked everywhere I know to look (supposedly) but if you find some easily locatable solution that I have missed, please feel free to call me mean names and share the solution with me. Otherwise, this is what I have tried so far (I will start from the beginning):
First, the 4.3 OTA update bricked my phone. I hadn't rooted my N4 yet because it was an updrage from D1 (yes, big jump). I decided to root the phone and install a custom ROM. Can't be too hard right? Its a Nexus for crying out loud. WRONG. Well I rooted pretty easily, and installed my first custom ROM for N4. To install this ROM, I had to erase boot.img, system.img, and userdata.img and then flash each individually from the ROM zip file I downloaded. This worked! I was winging it and it worked out. However, from then on, EVERY ROM I tried to install ended up in a bootloop. I have wiped cache/data, dalvik cache, and even my own (c)ache before flashing new ROM. They all end in bootloop (never ending).
I am able to revert to stock 4.2 easily every time. However, any attempt at installing a custom ROM from there is void. Today I downloaded 4.4.2.tgz from google and ran flash-all.bat. Everything works great! Until I try to boot up; bootloop. I fastboot format this and fastboot erase that, then fastboot flash each .img individually. I fastboot flash new radio, new kernel, etc. etc. but still bootloop.
I really am clueless as to what I am doing wrong or how I screwed myself somewhere along the way, but I am humbly coming before my superiors and asking for help. Please offer me the simplest solution and call me dumb for not seeing it, I will hold you in my heart 4eva

This is why once I have my phone rooted, there's no turning back to stock.
Are you sure that you wiped system, along with everything else between adventures? (factory reset via recovery)

Ok, gonna make a suggestion, and it's totally on you if you want to take it, and of course I won't be held responsible. I have had a bootloop or two on my G2 (the original), I would get impatient and pull the battery. (wish the Nexus 4 had a removable battery) Without fail, that cured the bootloop. Just remember, that was a G2, not a Nexus 4.
Don't ask me why it worked because I have no clue.

I have cycled power a few times during the boot to no avail. I also just reverted back to stock 4.2 and then installed OTA 4.3 update hoping outcome would be different (definition of insanity according to Vaas). I don't know what to do. It's just not in me to run 4.2 forever
