Possible Bricked Tablet - Please Help!

I think i may have bricked my nexus 10.. I was trying to install the chainfire3d application from the market, and when it rebooted, it wouldnt go past the X logo. waited for a long time, so i tried a hard reset, and still nothing. So i figured i would try using the toolkit to help fix. tried to relock, flash, and re-unlock, and it wouldnt work..after the step where you go into factory reset/wipe, it woudlnt go further. I cant get a custom recovery to install, it wont save the file. tried doing that step separately, and it seems to stick on sending the file over. this seems to be a common issue with anything i try.
The screen says:
"sending TWRP touch recovery..
sending 'recovery' (7246 KB) ...
and is just stuck there. this seems to happen in several places, with a few different things ive tried. When trying to flash the stock image, it will get stuck in similar places, perhaps not with the recovery step, but with a portion of the stock image. Been at this for a couple of hours... any help would be greatly appreciated!.
Also, as of now... it wont boot past the google logo. I can get it into fastboot by holding down the buttons, and I can get it into the stock recovery, but thats it. I don't even think adb is detecting the device. I have a feeling that may be a major roadblock to getting this thing fixed. Does anyone know how I can get the tablet to be detected by adb if i cant even get past the google logo screen at boot?
Update 1:
Still cant unbrick my device. any time i try to transfer or flash files to it... it stalls, and if i disconnect the device, i get this error:
FAILED (data transfer failure (too many links)).
Your Device will now boot into Android and detect ADB mode.
problem is, it doesnt reboot, and even if it did, it wouldnt be able to boot into android, since it wont go past the google logo when the device turns on. in fact, i cant even turn it off. only way to turn it off would be to wait for the battery to drain.
If this helps, here is what it says on the fastboot screen:
Device Information
Product Name: manta
Variant: wifi
H/W version : 8
Bootloader Version: MANTALJ12
Carrier Info: none
Serial Number: *********** (not going to publish that, lol)
LOCK STATE: Unlocked
Reboot Mode Flag: none.
anyone have any ideas at all how I can salvage this thing? Im kindof embarrassed honestly. Ive had 5 android devices prior to this one, and have rooted, flashed, and reflashed each of them countless times, and never, ever ran into this before. I could really use the help.
Quick note:
I just noticed that when i try to flash anything to the tablet, the following appears under the rest of the info i listed above.
FASTBOOT STATUS - DATA00713800 (this text is highlighted in light blue)
Update 2:
ok, so i tried to do the factory restore, and am running into the same wall as always. here is the text from the window, perhaps that may clue you into the problem:

*Bump* That's really unfortunate. I managed to fixed my soft brick after unlocking and flashing TWRP with a factory image. There was no highlighted blue text, everything went smooth. I hope your issue get fixed
P.S. I did not use the toolkit. If you can boot to your bootloader (fastboot), try running the shell/batch scripts included with the factory image? (This is just following Google's instruction on the factory image download page)

Did you try to run e2fsck on all partitions (boot, system, userdata) and check whether there are any errors?
You can run it via adb once you boot into TWRP or CWM recovery. Here is more info:
http://forum.xda-developers.com/showthread.php?p=34923662
Ps.
I also bricked my nexus 10 while transferring files on it in windows. Nothing so far helped me. e2fsck doesn't see any partitions
I believe this is something to-do with a corrupted flash memory. Your case looks about the same.

I cant get it to load a custom recovery! any advice on how to get that going?

So, if you run "fastboot boot twrp-image.img" under your current bootloader it doesn't boot it?
Also, If I remember it correctly, you can also boot in to a existing recovery and then run shell commands via adb.

Dumb question, if using a desktop PC are you using the front or rear USB ports? I had a similar issue where it would just get stuck on the "sending system" message. Switched the USB from front port to back port on my linux box and it solved my problem.

What I meant was, you can now run e2fsck and check all partitions for consistency. Refer to a thread that I posted a few comments back. You can run e2fsck either via a terminal session in TWRP or via adb shell.

couldnt get the command to work via adb, so i tried it using terminal inside TWRP, and this what it spit back at me:
/dev/block/platform/dw_mmc.0/by-name/system: clean. 11/51296 files. 6651/204800 blocks
i have no idea what that means, nor what else to do....

well.. i loaded it into the bootloader, unzipped the factory image, and everything inside it into the platform-tools folder in my android sdk directory on my pc so i could use ADB
then i did the following via adb
fastboot flash bootloader bootloader-manta-mantalj12.img
fastboot reboot-bootloader
fastboot -w update image-mantaray-jop40c.zip.
the first time it got stuck pushing the system.img file, i let it run for almost an hour before giving up. then the battery on the tablet died. let it charge for about an hour, plugged it back in, reran the last command from above, and for some reason, the whole thing went through without a hitch. wish i could explain why it worked that time, but I cant. hope this helps someone else that encountered the issue.
thanks again to everyone that offered any input!

Whew! So glad you finally had success & thanks for sharing. I'm reading up, research, etc. I received my N10 yesterday. I'm getting ready to unlock/root today.

Hmm, did you try the flash-all.bat file that comes with the factory image? It does those 3 commands, + erases all partitions automatically.

That's exactly what I did. Just followed the factory image flashing instruction on google's page(where you download the image file for N10). Did you figure out why it wassnt able to transfer the first time?

Bootlooping, ADB not detected, can't enable debugging

So, where do I start?
I bought this device (Nexus 2013 Wi-Fi) in late november and have not updated it since. I attempted to update it today (because I received a notification to do so) to 4.4.2 (I think).
It restarted after the update and I've been stuck in a bootloop at the "4 circles".
I have done the following:
- put the device into the boatloader
- installed the nexus root toolkit and attempted to flash stock + unroot the device to the images: 4.3 (JSS15Q), 4.3 (JSS15R), and (KOT49H)
- this was what my output looked like

When its finally booted back up, please remember
to re-enable USB debugging if you plan on using
the toolkit to perform other operations.
NOTE: If this process was too quick and your device
is still in bootloader mode, then flashing stock may
have failed or been incomplete. Simply check the
log above: if you notice it skipped steps because it

mode in the toolkits options menu and trying the

​
- And no, I have not tried the force flash.
- I have tried all the drive options and maybe I'm not following the directions properly but that does not seem to work (and it may be the main problem for all I know).
- I'm also not sure if I thoroughly removed all google nexus-related drivers prior to running the nexus root toolkit, so there may be that.
- I've tried some brute-force methods inspired by things I've seen here, as in:
un-packing the factory image files into the platform tools part of the android sdk files and run the following commands in the cmd.exe: fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot erase system
fastboot flash system system.img​ - My guess is that the problem lies with the fact that I cannot put the device in debugging mode and I cannot have it recognized by adb.
I'm not sure where to go from here and I'm rather frustrated. Please let me know what solutions I should re-try (but perhaps more carefully?) and new ones that I should know of.
I appreciate all your help

Download the factory image. Extract it. Inside is a zip, extract that too. In there you'll find the cache.img. boot into the bootloader and in a cmd window on the pc use
fastboot flash cache cache.img

Soft-bricked my phone

FIXED
Hi all! Been a member of XDA for a few years now, but only just had the pleasure of becoming a nexus user. Yesterday I decided to install the Android N preview to try it out, but decided I didn't want it on my phone. So when I got home, I wiped the phone and proceeded to flash the factory image, but no matter which image I flash it, it says "error: update package missing system.img". I have tried manually flashing each file in fastboot as I have seen in many threads, but nothing is working. I have tried restoring old TWRP backups and flashing custom ROMs in TWRP, but nothing is working. Help!

Hi, I followed the steps exactly, before updating my 6P to N developer preview, I had previously flashed the factory image. Thanks!

Unzip it yourself and flash em each manually.
Make sure you have the lastest fastboot tools. Im going to go out on a limb and say yours are out of date

The logs make me feel like the file you downloaded is corrupted. Check the md5 maybe?

Probably a corrupt download, did you check the MD5 after downloading?

It looks like you are not in the directory with the boot.img, et al. (your post shows no boot.img,, ... ) Make sure you unzipped the image. There are 2 files you need to unzip, the one containing the bootloader and radio. In that unzipped folder will be another zip. Unzip that second folder and you'll see the boot.img, cache.img, et al. The change in to that folder from your terminal or move those files into the folder you created (if following Heisenberg's guide), then proceed.

Hi all! Been a member of XDA for a few years now, but only just had the pleasure of becoming a nexus user. Yesterday I decided to install the Android N preview to try it out, but decided I didn't want it on my phone. So when I got home, I wiped the phone and proceeded to flash the factory image, but no matter which image I flash it, it says "error: update package missing system.img". I have tried manually flashing each file in fastboot as I have seen in many threads, but nothing is working. I have tried restoring old TWRP backups and flashing custom ROMs in TWRP, but nothing is working. Help!

I think you are using an old version of fastboot. Update it and try again. Problem was fastboot couldn't allocate enough system ram to hold the whole image or something. In the newer fastboot the file transfer was broken in to several segments.
Maybe try another USB port too won't hurt.

Thanks!!! It actually worked. Not sure what was wrong before, seemed as though every file I downloaded off of the google website was corrupted. Cheers!

You're welcome!
Like I said I had the same problem back in November. It ended up being an outdated version of fastboot like others have stated. I coyld flash my friends Moto X Pure but not my Nexus 6P..mit was awful and brain racking. Glad all is good!

Search YouTube for "How To Get Back To KitKat On Nexus 7 (2012)." I followed a video by RyTech and it was pretty straightforward--I had to show hidden folders to find the AppData folder but it was easy after that.

Unable to access Nexus 7 following previous failed Flash
Think the Nexus 7 has finally bricked. As suggested, I ported the Studio Platform tools across, however the fundamental problem is that previously attempt at Flash will have deleted the OS and I can't get into bootloader as I assume you need the OS to re-enter Developer Mode?
Connecting Nexus to PC, I do get the connecting (PC) audio to confirm the connection, however the display remains blank, despite on/off & Volume up/down combinations - no devices found when 'ADB devices' entered, and as you'd expect, no response to 'adb reboot bootloader' .
Help!
Many thanks.
