it stops at the google screen and just freezes

How are you certain your recovery is gone? You might just be stuck in bootloop. Your best bet is to use toolkit to get you into recovery. Whether Twrp or CWM. From there youcan flash a new kernel and see if it fixes it or use it to restore a backup.
I had similar issue where it was stuck on boot screen. I ccouldn't enter recovery normally. Only way was hooking it up to a pc. Then using a toolkit to make the tablet go into recovery. Then from there, I could use recovery on tablet itself and restore a backup. From there I was good again. Problem solved for me.
Try one of the other toolkits, like Sambra one. Make sure drivers properly installed though.

It's an easy fix, just use wug's toolkit and flash the stock Nexus 7 image. It will be like brand new. I don't think you had a very major problem at all to begin with just a minor bootloop, but this far along I'd restore it to stock and start fresh.

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.

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

ok im about to throw this tablet out the window. was messing around with the tablet and it auto installed ( well at least tried to) the 4.2 update. it downloaded the update went to install and now im stuck at this screen(check pic) and cant even get it into recovery mode. im at the point now to cut my loss and say the hell with it. anyone else have any ideas on whats my next step. the thing that wireds me out is of the roms ive been able to use it all works great for only about 5 mins. it seems like the more i touch the screen to do anything it will freeze on me(it will do it after 5 mins or so after a restart). https://www.dropbox.com/s/arnauysa4oglp5b/2013-05-21%2018.37.24.jpg

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.

[Q] I think I broke it... no os... computer can't see phone

I was happy that I rooted the phone and got Japanese fonts working.. but I wanted the ability to adjust the gain/volume of my mic headset and tried to install a rom to do that. I used the Nexus Root Toolkit to root the phone and do an entire backup. Then I flashed the rom. It didn't take and I really had no idea why (being noob). So I go on youtube and see what i can find for flashing a rom. I see that you have to delete your old OS in order to install the new one.. ok.. risky but I did a full backup right? Well when I tried using Nexus Root Toolkit to install said rom the phone ended up with a screen with a menu with some options including to delete the OS. So I did that. Then I tried to install the zip file which was now on the phone thanks to Nexus Root Toolkit.. but it still didn't take. Okay. I gave up. I rebooted.
But I have no OS. And my Win7 machine can't see the phone. I tried deleting and installing drivers again and it doesn't work. I can boot to the fastboot screen (the one with the Start at the top and cycle through options like recovery mode). But the computer can't see the phone. Nexus Root Toolkit seems to be of the opinion that I need to enable USB tether debugging mode on the phone.. but there's OS to do that.
Is it hopeless?
btw I think this phone is great. I would prefer maybe a slightly smaller phone but i can't believe how cheap it is, beautiful screen, fast, responsive. Amazing.

Flash the stock image, comprehend what you are doing while you flash the images, and never use a toolkit again.

Sorry i accidentally clicked your thanks button. If you have a recovery installed then just flash a rom.

windows 7 can't recognize the device now
Thanks very much for the reply. I still am thinking it's hopeless... I followed your link and I'm attempting to follow the directions...but here's where the problem is. And basically why the toolkit can't help me either.. (I agree it's better to understand all steps and yet I'm lazy..)
Attempting to install drivers for Nexus 4...
*** cut and pasted from OEM USB Drivers install guide **
Locate and expand Other device in the right pane.
Right-click the device name (such as Nexus S) and select Update Driver Software. This will launch the Hardware Update Wizard.
***********
The phone doesn't exist in device manager. Perhaps its lack of an OS keeps windows from realizing what the heck it is?

Do you have a custom recovery installed?

no custom recovery

Not on purpose. So probably not. Actually I doubt it. I am looking at Nexus Root Toolkit and I see the checkbox for Custom Recovery and I know I did not check it when I rooted.

soft brick?
The computer does acknowledge the device to the extent that it installs Android ADB (if memory serves which who knows).. but otherwise it doesn't know it's a Nexus 4. It thinks it's an MTP USB Device.
I am playing with Nexus Root Toolkit a bit (it did do the backup of the phone afterall... ) and it apparently flashed the stock kernel.. that's the 1st thing I've been able to do to between the phone and the computer. Now Toolkit is telling me to wait 7 minutes before assuming soft brick.
I am thinking it is soft bricked? gonna wait a few more minutes.

well I ignored the lack of nexus 4 drivers...
and just followed all the directions anyway for the command line install. When you go to the LGE website to get drivers.. you don't find any. At least I couldn't. Just manuals to download. But I got success messages all along and it rebooted when I told it to and stuff.. but it's just sitting at google. It isn't going past the google screen. The computer calls it an MTP USB device with a big exclamation point next to it.

clockword recovery
I might have it. It might have been installed when I did my full backup perhaps. If it's the reclining robot with a red triangle and an exclamation point then yes. I can wipe cache, wipe data/factory reset, and apply update from ADB, or reboot. I've wiped the cache and done a factory reset... I'm gonna try:
Default [HOW-TO] How to flash a factory image / return to stock / unlock / root #
Again.
And hope.
It's a new phone so I am still within the 14 days they give to return it.. of course if it's a brick when they get it back... heh. Okay it's a 100% brick it does turn on just not boot up...

it works omg

Well 2nd time through was the charm.. and not worrying about nexus drivers too much.
Thank you very much for the link. I can't say I really understand everything more but I am happy that I seemed to have killed the phone in the worst way and yet still got it working.
I was going to go back to the iPhone 5 (and lose a lot of money haha). I'm glad this one is working. I genuinely like it more than the iPhone and I save several hundred dollars.
If anyone's googling in a similar situation.. what I did the 2nd time through was use recovery mode on the phone to restore factory default and clear the cache. Then I did all the steps outlined in the above link again. I think that if it doesn't work the first time it's worth doing it again carefully.. and maybe a third time if needed. Wow. It works XD.

[Q] Baffled, Confused, Stuck... sniffing KitKats

Hello guys
For some reason I decided to test out the CM and Slim 4.4 roms, but did not see that there were issues flashing with TWRP... so flashing failed with both these ROMS. I did not read the ops on Slim and did not see any warning about TWRP on the CM, so began wiping stuff to try make the flash happen, eventually wiped too much, and now I cannot boot the tablet. Worse is I have also wiped the zip files from the tablet so now I have PhilZ Touch CMW recovery but nothing to flash and this Recovery does not suppot OTG memory, so I have nothing to flash.
SO, tried my full version of Nexus 10 Toolkit to sideload the zip, but Toolkit never gets past "Toolkit Waiting for ADB mode".
I don't know the manual commands to try flash one of these roms, but at this point, I would be happy to just go back to stock, and cant figure how to get to Download mode, there is no home button on an N10.
It seems my safest bet, if possible, would be to get to download and flash a rom there.
Any ideas, much appreciated,
Mark.

From recovery power down your tablet and get into fastboot by holding volume buttons and power buttons at the same time. If this works then you'll be fine because from there you can get back to stock. Download wugfreshs nexus toolkit. Use the option to return to stock and check the one that says stuck in bootloop but can access fastboot (or something like that) then plug your tablet in while its in fastboot mode and go through the steps. It'll have to download stock factory image unless you already have it and browse to it but the toolkit will do everything and get your tablet working again. Don't worry too much its usually not as bad as it seems. The same thing happened to me and I panicked and it turned out to be an easy fix. If you need any more help or more detail on what to do just ask

Nexus 7 (2012) WiFi Soft-bricked

Hi,
I have an old Nexus 7 (grouper on completely stock KTU84P, unrooted) that I gave up on a long time ago and recently found it again. I charged it up and the Google logo came up. And then the 'Start' in green with a arrow around it appeared. It was stuck. I could use the volume buttons to power off or enter recovery but that was it. Once in recovery, I tried wiping cache but that got stuck on 'Formatting /cache'.
Now, I do remember it got very sluggish when I last used it a long time ago to a point that it just used to freeze up on me every few minutes. Maybe, i hope not, but maybe it's got something to do with the notorious flash emmc(or whatever it was called) that this device has. If not, I'd love to be able to use it again in any way possible.
TIA.

Is it possible to connect via USB?
If so, then try a clean flash.

It is possible. I tried sideloading a stock OTA package (using just adb) called '4939a9ff6d10c495beaed26ac96228246f724272 signed-nakasi-LRX21P-from-KTU84P 4939a9ff' but that failed. Then I tried the Nexus Root Toolkit's flash stock feature. It connects and goes well until it reboots to unlock the bootloader. The display doesn't turn on but the computer recognizes a new device called 'APX' with hardware id 'USB\VID_0955&PID_7330&REV_0103'. I've tried booting it into custom recovery using NRT but that didn't work either.
According to the current '3e' stock recovery I remembered that it used to run KTU84P (4.4 Kitkat) and never ran Lollipop which it seems caused some trouble too.

Please try Wugs Toolkit.
That is an easy program to do all kind of repairs.
It never failed me.
