So today I was minding my own business, riding the subway and listening to some music when my Galaxy Nexus decides to reboot itself. After this, it gets into a reboot loop (never getting past the Google logo).
I tried restarting the phone into fastboot mode and using the recovery option, but I end up getting the icon of the android on its back, chest plate open and a red exclamation triangle thing coming out of it. I assume this is bad
A little back story... this is the GSM/Euro Galaxy Nexus. I've been using it for close to 6 months most likely and have never rooted/unlocked it. In actuality, I don't think I've ever done anything with it out of the ordinary (like I have in the past with other android devices). In fact, I don't know if I ever even plugged it into my PC via USB before (thus no drivers, may have never set it to USB debugging enabled).
Is there anything I can do here? I tried looking at a few options (Such as the WugFresh Galaxy Nexus Root Toolkit, which has a Stock resetting option), but since I never enabled USB debugging and installed drivers before the phone decided to go and brick itself, I don't know if I'm actually stuck...
What do you think? Is there an option I have not yet considered? Or am I going to try and convince Samsung to honor my warranty or something?
Moved to Q&A, please pay attention next time where you are opening a new discussion
When you see the android on its back you have to hold vol. up + power to enter the options.
There you can wipe data and reboot to see if it will boot up again.
If that doesn't work you can try flashing the stock images. Those will require you setting up fastboot on your computer. There are many guides on how to do all of that.
Good luck.
If you can get into Fastboot mode just fine, then hook it up to your computer and flash the stock images. It'll revert you back to stock fresh and you can go from there.
We also need to teach people how to debug at basic level at least. If we just teach them how to solve it without caring about what went wrong... they've got the phone might as well learn a few things more.
And yea, i know most couldn't care less. Also, this is no brick - this word very much starts to annoy me when it is incorrectly used and that seems to be getting typical around here. Most likely wiping data/factory reset from stock recovery will allow op to boot up again.
i had the same happening to me under stock. after quite some time it went into a bootloop out of the blue.

solved it. my data was gone, but at least the phone worked.
then i decided to root and use a custom rom and it never ever happened again.

Sure we do but as long as :
1. people start threads that suggest they bricked their phone and
2. all they had to do is Google some around to discover that what they see is a stock recovery and
3. discover what they can do to solve their problems (like most of us do to solve our problems)
I think they couldn't care less about debugging... How sad as it may be.
If you discover problems with a device that is sold as much as the GN it is highly unlikely that you were the first to have that problem. If you are: just post away.
So I tried using the wugfresh toolkit last nigh to root since from what I've read all the nexus devices use the same method to unlock the bootloader and such. This was likely a mistake. After figuring out I had to change the device to PtP I managed to get to the unlock bootloader screen on the device, at which point it became unresponsive. I turned it off completely, and at that point it wouldn't boot at all, it would just sit on the nexus logo forever. I also couldn't fastboot, holding down the power, volume up and volume down buttons seemed to do nothing. So I let it run down last night in hopes of starting on a fresh charge. Now the device doesn't seem to want to charge at all. I plugged it into both my computer and wall charger through the usual usb cable, and the screen isn't showing any indication of charging. All I saw was the notification light blinking in short bursts after initially plugging it in, and now not even that is happening.
Ideas?

Exactly....I can't reboot into recovery because I can't fastboot into anything. I'm not sure how this helps.

A few points.
First, this is why I highly discourage 'toolkits', especially on Nexus devices. There simply is no reason to use them and many reasons not. It is much wiser to learn how to do things manually, as it makes troubleshooting problems much easier and is less likely to cause a problem. For example, to unlock the bootloader, you could have issued a single command to accomplish it.
Second, as I don't use toolkits, I can't say exactly how the one you used works, but it most likely automates that 'fastboot oem unlock' command, which IS the same for both N7 versions. If so, it shouldn't have caused you any issues.
Third, assuming all you did was attempt to unlock the bootloader - and not flash any custom stuff, root the device, etc. - you should not be running into this issue. If you did try something else, that could certainly explain some of the problems you have. There is certainly a possibility that your device is defective. It it truly won't charge or function at all, I would highly recommend you return it for a new one. If it's dead, there should be no reason why they won't take it back.
Next time, I would recommend doing things the old fashioned way .

It turns on, it's on at the moment actually. It's been sitting at the nexus logo for about ten minutes. And I still can't load into fastboot, holding down those three buttons does nothing. I'm not even sure why the device froze at the unlock screen. I'm trying to start up the old fashioned way right now, following this link http://forum.xda-developers.com/showthread.php?t=2379618
I've managed to make my way to the platform tools folder in a command line, but running the reboot bootloader command there does nothing. It simply says device not found. I don't think my computer is even seeing the n7 properly so it can't reboot it. I don't think its defective, but I don't know where to begin to fix this using the old fashioned way either....

I second all that's been said here. While toolkits can seem attractive, it's really quite simple, and much safer to do it manually once your take an hour to learn your way around the Android-SDK (way easier than it sounds, I promise).
I like toolkits, seriously, but they hardly ever work. I usually have to drop to a shell prompt and run the commands manually anyway.

To get into bootloader mode, you hold down POWER+VOLDOWN - not all three buttons. Make sure you turn off your device first (hold down power until it shuts off), then hold down those two buttons.
If it gets to the nexus logo, that means your bootloader should be OK, which means you can probably recover.
The 'adb reboot bootloader' command will not work until the device is booted up, your turned on developer mode and USB debugging, and you allowed your computer to connect.
Assuming you can get into bootloader, look to see if you did successfully unlock it or not. If you didn't, try the 'fastboot oem unlock' command.
If you continue to be unable to boot normally, you will likely need to flash the system image. There is one floating around here (system.img). You can do this in the bootloader as well (fastboot flash system system.img).

I understand that and have absolutely learned my lesson. What's confusing me at the moment is installing the drivers listed in the link I posted. All that's there is a zip file, no exe or anything which is what I'm used to for installers. I was able to reboot my nexus 7 into bootloader before with the toolkit, so I know I had the drivers installed properly at some point. The toolkit installed a universal ADB set which I'm thinking should work. I don't know what to do to get the device into bootloader to follow the instructions.

So I'm able to get into the bootloader, but its not responding to the command line entries. My computer brings a popup anytime the nexus tries to do a regular boot, where it just sits at the logo. The popup explains that the device is unrecognized. I've uninstalled any devices that resemble the nexus in device manager, and have tried repeatedly to update the driver manually by pointing it to the usb driver folder within the sdk. Doing that simply says windows is unable to locate the correct driver. So I think my device is where it needs to be, I just can't connect to it from the command line at the moment.
First of all, what made you try the toolkit(effective as it is) on the new Nexus...? Couldn't you just sit down for a day or two enjoying stock experience(abominative as it is)...?

Unlocking the bootloader will always result in your device getting wiped.
So it makes sense that you do this first, this way you don't need to setup your device twice.
It also has nothing to do with stock vs custom. I have an unlocked bootloader, custom recovery and am rooted. But my device is still completely stock as far as the OS goes. The only thing I might change in the future is a custom kernel, as I am usually fine with things 'stock' from a user perspective on Nexus.

Honestly I had completely forgot that the initial unlocking does the factory reset. I got caught up in booting up the device and installing a few apps to try it out, to the point that I completely blanked on the reset haha.
I tried a bunch of different roms and verions on my gnexus and old N7, jumping between CM and PA mostly, and I got used to just having a backup ready and not worrying about a data wipe. I've mostly stuck with PA because the pie controls are fantastic on both devices and I've come to get used to the added screen space. I'm perfectly fine with the stock experience outside of pie controls, but I do love customizing my device and the custom roms allow for so much freedom in that regard.

Okay... so its a zip file.... go to device manager and it should show you some android driver or nexus 7 or something.... right-click on that and choose update drivers... choose manual method and select the folder hat you unzipped...
then use fastboot to flash factory image...

I actually got it successfully up and running, unlocked and rooted and everything. The screen and dual speakers alone justify the price for sure, and the speed difference is noticeable. Riptide 2 seems to run alot smoother on this than my old N7. I'm also aware that in general a clean install runs better than something that's been used for a while, so perhaps that's part of my percieved performance gains. In any case I'm more than happy with my purchase, and am looking forward to getting my chromecast tomorrow!

Why would I wait for a toolkit?
This is a Nexus device. You don't need a toolkit. All you need is two brain cells and a willingness to learn. You can unlock, flash custom recovery and root in a matter of minutes with nothing other than the Android SDK. Toolkits cause more problems than they solve.

ok, not a toolkit.. I give you that, but was the stock experience too intimidating...?
personally, i'd nuked htc sense when i got thoroughly bored with its great buttery ui. i like the aosp experience, rooted or not.
and i didn't know that we don:t need toolkits fpr nexus devices, cuz i've never happened to own one.
I'm hoping someone might be able to help me recover my Nexus 7 which appears to be bricked currently. It is the 2013 version, and it was never rooted initially and was running stock firmware. (By the way, I'm not the most proficient with messing with my Android devices or even with the terminology, so I apologize in advance if I might require clarification on some of the responses).
A few days ago, I woke up to discover that somehow my home screen had reverted back to the way it was upon initially getting the device. This wasn't a big deal since I didn't lose any data or apps, but I figured something might be wrong and even posted about it on Google's product forums. Then, last night, I attempted to update to 4.4.3 because it had been prompting me to do so for a week or two. It downloaded and attempted the update, but it failed. It then eventually restarted, but upon loading up Android I got an error message that stated:
System UID's Inconsistent
UIDs on the system are inconsistent, you need to wipe your data partition or your device will be unstable
with a button to click that says "I'm Feeling Lucky" - I clicked the button figuring I could at least get back in to back up my data, but after about 30 seconds the device just rebooted again (all I managed to do was accidentally click the Chrome icon) and now it is just stuck at the initial boot-up screen displaying the Google text logo.
I have tried to hold down the volume button and hit power, and I get to a screen with 4 options I can cycle through: Recovery mode (which will just put me back the Google text logo), Power off (which turns off the device), Start (which puts me back to the Google text logo), and Restart bootloader (which brings me right back to this menu options page). I'm attaching a screenshot of this page.
I spent about an hour on the phone with Google support, but they were basically useless. I then did some research and downloaded Skipsoft Unified Android Toolkit and was able to get the device to be recognized when it was in that 4-option mode by the Skipsoft Toolkit. However, all fastboot options I tried didn't seem to succeed because the Bootloader was locked. I figured I would try to unlock it, and it told me that in doing so it would wipe my device (so be it I figured since I had already pretty much kissed my data on there goodbye at this point). However, it seems to try and wipe it (even giving me a prompt on the actual Nexus 7), but then just sits and does nothing that I can see (see attached screenshots).
Anyone have any ideas/suggestions? Thanks so much!
To be safe, with a stock device that was not rooted... I would go ahead and use the Skipsoft program to flash the stock image back on the device. This should alleviate any future issues with the OS on your device.
I believe it to be Option #9 on Skipsoft.

Thanks for the reply - I attempted your suggestion, but it didn't work because the Bootloader is still locked; and attempting to unlock the Bootloader seems to stall on erasing userdata.
Any other thoughts? Thanks!

Put the device in bootloader mode (power+vol down), open fastboot.exe and type fastboot oem unlock.

I changed the wrong link in my signature. The ADB link correctly points to version 19.0.2 now. Try that one. Try a different cable if you have one, try a different USB port if you can.

Tried two different cables on two different USB ports with the new 19.0.2 downloads you posted - still having the same thing happen. Could it be the computer I'm using, or the drivers I installed (I used the Skipsoft Unified Android Toolkit drivers)? Or is my device just totally bricked and unrecoverable?

Ok, so I removed the Clockworkmod ADB drivers from add/remove programs (or uninstall programs - whatever it is called now on Win7), then I went into device manager and deleted the driver for Google Nexus BootLoader Interface, and then I rebooted. After the reboot, plugging the Nexus 7 in showed no driver detected, so I downloaded your Koush Universal ADB drivers, extracted them, and used them to install the Google Nexus Bootloader Interface drivers again (that's what it detected for my Android when I pointed the device listed in device manager to the extracted folder).
I then ran "fastboot oem unlock" but it's still getting stuck at the same place: (bootloader) erasing userdata...
Anything else I can try?

Hi,
I have the same issue since yesterday. When I pulled my nexus from my backpack (charged 12 hours earlier) its battery was drained. After charging it nexus stucked on google screen during normal or recovery boot. Oem unlock also hangs on erasing userdata. I'm looking forward for any solution to this.
Maybe some ****ty update? I've got the LTE version.
Anyone have anything else I can try?
I'm currently working on getting ASUS to replace the device under warranty - but they want me to send it in first, and I'm concerned that while I can't access any of my data on it, the data might still be there and potentially accessible to others (and I'd prefer to not have all of my confidential data that I stored on there accessible to anyone else). Unfortunately, ASUS won't replace/repair it unless I send it in, so I'm between a rock and a hard place...
Any help or advice is greatly appreciated!
Thanks.

When I got it was wiped. Flash is on the mainboard so there was no way they could save my data. They do not migrate your personal stuff.
Now its working like new. In fact it has all new guts except battery and screen.
Only problem is that now auto brightness sensor is giving crap instead of useful data. I don't know if its hardware related or just 4.4.3 issue.
Seems a few are having the same problem as me after trying to flash 5.0
My Nexus will no longer boot past the Google Logo (White one). I can only access the Bootloader. When I try to go to recovery I see the TWRP logo but stays stuck there. I tried flashing a new image a few times but always had the same problem.
I then tried to relock the bootloader and unlock again again to prepare a fresh install. This is where it gets worse. I managed to lock the bootloader but I can no longer unlock. I get to the screen warning that data will be wiped if I choose "YES", but when I do proceed, I stay stuck on "Erasing userdata...". I left it for 5 hours and was still stuck with the same message.
I cant see what else I can do now.
Ive read a few threads saying its a motherboard issue. Seems weird that it appeared when I tried to install Lollipop. Also seems Im not the only one.
this worked for me
I'm sure someone wiser will respond to you later but ..... I've been in a similar situation.
I use Windows 7 64bit and always connect device with usb 2 port (i.e. not usb3).
I was getting stuck on the google logo with an open lock symbol low on the screen - indicating unlocked bootloader. Like you could get into recovery but unable to get any further once there.
Try using Wugfresh's Nexus Root Tool. Look in the development thread. I'd suggest reading his faq's.
Download and install the latest version 1.9.6 (as I recall) - I had problems when using the earlier versions.
Get an stock image downloaded.
Then you should be able to flash the image using the force flash method he mentions in his faq. You set it in the options menu.
Set USB debugging on the device and usb options for storage to ptp rather than mtp - that's what worked for me.
You'll probably see repeated "installing driver" messages and new "open location" popups as you go through it.
(if your bootloader is locked you'll need to unlock it first. - just re-read your original post and I'm hoping that the latest NRT version will get you unlocked OK.)
If you have problems with this at first try going through the driver installation section of the tools.
After that you can use the same tool to root it. That didn't work completely but did allow me to use an OTG flash drive. If you need full root there's a patch you need to flash - Key Pie patch - took me a while to find it but it's somewhere on these forums.
After the problems I had everything went smoothly in the end. Just be prepared to watch it go through various rebootings while the magic is being done.
Apologies if this is a bit haphazard - I tend to try and rush through things and then forget what it was exactly I did!
I have tried NRT but cant do anything as I cant unlock the bootloader. I have tried both Fastboot and NRT, they both block at "erasing userdata".
Just a thought
Sorry to hear that.
Have you tried "Flash Stock + unroot" with the "Soft-bricked/Bootloop" option in NRT? I now recall that's something that helped me get mine recovered. Just a thought.
I recall reading forum posts that suggested I might have motherboard issues - but I didn't believe it was likely to be the case so I kept trying.
Tried all NRT options including force flash.
Problem is none work with the locked bootloader.
Nexus Root Toolkit v1.9.7 out now
Change log:
What’s new in Nexus Root Toolkit 1.9.7: November 16th, 2014
· Included the latest Masterlists to prevent users who never utilized the “Update” in the kit from getting the AutoIt error (for KTU84P Nexus 7 2013). This error was due to the modified boot.img for that build being accidentally removed from the server. Its was then reuploaded and the masterlists were updated, but those users who never updated would still get the error.
· No longer will the “Force Flash” recommendation be made to N4 users, because it seems to cause a bootloop – however factory resting will fix that either way.
IDEM
I spent exactly the same as you, I also lock the bootloader and now I can not do anything, always get "write failure" and when I try to unlock stays forever "erase ..."
There will be some way to revive it?
Cursed Android 5.0!
If the problem is confirmed to be Android 5.0, Google can help solve these problems?
Use the instructions to reflash your bootloader.
http://blog.laptopmag.com/how-to-hard-reset-a-bricked-nexus-7-with-your-pc
Note replace the instructions to download 4.1.1. with the correct version of the ROM you want to flash. Make sure you grab the correct version for your device. Flashing the wrong bootloader can hard brick your NEXUS with no chance of recovery. Also don't relock your bootloader unless you are certain that you will never want to flash again. Unlocking wipes all of your data and you also can't be rooted if you lock it again.
Doesnt work. Cant get passed the first step. After 1 hour its still "erasing boot..."
I flashed 5.0 successfully... You can't send it to Google with warranty? Try on other computer, do it manually using fastboot and don't give up!
As long as you can still boot into Fast Boot..
Your device can be restored..
I suggest using Wugfresh's Nexus toolkit
http://www.wugfresh.com/nrt/
The issues coming from the latest upgrade are common problems when ever we upgrade..
Its always better if you know how, just use the Nexus Toolkit and install the factory image..
Then it will sit at bootup for about 5-7 mins, then restore your apps... Profit
OTAs will always cause issues with some devices..

Again.. I cant unlock the bootloader whether manually trying with fastboot or running NRT. Flashing a stock image is not possible.

If you have not tried the latest version of NRT, you may of fried your locked bootloader..
Regardless, don't give up... Someone will come to the rescue.. Nexus devices are pretty robust..
Try using another cable, make sure you have the correct driver, double check in Device Manager...
Then try again with the lastest NRT.. Mine just updated.. As a rule of thumb its better not to use a USB hub if thats the case.. Try swapping out your cable, make sure you have the Nexus drivers... I had to re install mine..

I'm in the exact same spot. Also, I know that I don't have USB debugging enabled, so not sure if I'm blocked out because of that. Very frustrating.
The computer sees the tablet though. If I click on List Devices in NRT Advanced Utilities, it shows my serial # fastboot.
update: I tried the Unlock command and it goes to the Unlock Bootloader screen. I click Yes, but then the device just hangs on that screen (I let it sit for 30-40 minutes). Ideas?

It hangs because its probably stuck at "erasing userdata". If you do it manuall with fastboot oem unlock you will see this in the cmd window.

I ve given up . Bought a Nexus 9. Wasted too much time on this.
Having the same problem
My Nexus 7 (2013 32gb wifi) was working just fine on Monday. Had an unusual freeze up when I was reading something on Adobe Acro., but a quick reboot had it running again. I remember a notification about a system update but didn't pay it much mind. Later that evening I went to pick the N7 up and it was stuck on the Google loading screen. Freezes at Google loading screen when I attempt Recovery mode from Fastboot. Fastboot OEM unlock gives me the same stall at 'erasing user data' as mentioned above (left it on for this for 12+ hours yesterday and nothing). I haven't tried a different cable other than stock yet but I have tried multiple ports and two different machines to unlock the bootloader so I can flash the OS. No other functions with NRT (1.9.9) work including forced flash+unroot. I can't even flash the bootloader or erase or format any partitions. Feeling a little SOL here and I think it has something to do with Lollipop update.
N7 was unrooted and used for reading for the past couple weeks, so pretty vanilla use over the recent past.
4 months out of warranty with Asus and they want an est. $100 for RMA. Google tossed me to them after dragging me through the basic stuff I've been doing the past few days. Going to keep messing with it I suppose once exams are over but feel like I'm running out of things to try. If anyone has any suggestions, questions or a solution, posting them here would be much appreciated.
My upgrade from 4.4.4 to 5.0.1 took ages. It was like bouncing the four small balls for perhaps 5 minutes. Just have patience.
I would recommend not to use xposed or titanium backup as I expect those programs mess with /system files and that can break the android upgrade script. Just disable any unwanted bloatware in regular application control. At least all my updates have been successful so far. Yes, I am rooted.
Good luck.

For Wugfresh excellent "Nexus Root Toolkit" to work you need to enable usb debugging in developer menu. You enable the developer menu by tapping a lot on your version information.
The usb debugging gets reset on every upgrade.

They quote you $100 RMA, but once you send it in they will send you an invoice for $200. $165 for the motherboard, $25 labor and $10 return shipping. I fought it and they eventually dropped $10 for the return shipping. Last time I ever deal with Asus.

When I boot up my tablet, I get nonstop error messages telling me things have stopped working. I tried getting help from someone else on a different site, and this is what they told me to say: I flashed the GROUPER lollipop ROM onto a FLO. Someone please help me!!! It's a totally clean tablet. no files on it except android.
Go to Google's Nexus firmware page, download the appropriate firmware, follow the instructions: https://developers.google.com/android/nexus/images
Only thing I don't know is whether or not you'll have to repartition the internal flash.
I'm a dummy.

i don't understand how to do all that though I'm not good with command prompts... and nexus root tool kit has done me no good. Could you dumb down the instructions for me?
Then it's time for you to learn. The page has step-by-step instructions. There isn't any way too dumb down the instructions.
You have to start somewhere. Now is a good time. If you had learned before, you wouldn't be in this predicament.
So sit down, take a couple deep breaths, then read the instructions a few times. Download the Android SDK and factory image, then get everything set up. Don't panic, it's not nearly as difficult as you're making it out to be. Stop psyching yourself out. Take it step by step. If you get stuck, leave the cmd prompt and post the issue you've run into here.
Might help if you type out the instructions here after you've read them over several times. I'm glad to help but you gotta take ownership of your tablet and put in some effort to learn and educate yourself.
Just try, I'm sure you'll understand it by the end of tonight or the end of the weekend. You don't have to be a master of fastboot and adb, I sure as hell am not. I never recommend the use of toolkits, especially by those with no understanding of fastboot and adb. Once you have a basic understanding of fastboot and adb, go ahead and use any toolkit you want because by then you'll know how to get yourself out of any jams using those 2 tools.
It is almost impossible to hard brick this device, even if you flash the wrong ROM on this device..
Download this utility and it will bring your Nexus back to life....

I'm officially giving up. Nothing works. It boots into the OS and then pops up a bunch of error messages. I've tried lollipop, kitkat, cyanogenmod, locked bootloader, unlocked bootloader, and I'm done. GR! Thank you though, for your help.

Nothing works? Just flash the factory image. Flashing Roms in recovery isn't going to help you. Before you give up, just use wugs toolkit to save it. If you give up without even trying the right procedure (fastboot flash factory image) then i recommend you not root again after you fix it. But wugfresh toolkit will fix it for you with a couple clicks.
I tried NRTK

The toolkit doesn't work. I tried that 9 times, both downloading my own OS to flash, and letting the toolkit download it. Every time it either boot loops it or does the error message spam thing again. That's why I was trying to use SDK... And that didn't work either. And my drivers NEVER INSTALL RIGHT, so it's all just slowly killing me inside...
Make sure fastboots working first. Put the tablet in bootloader mode by shutting it off then holding power and volume down (or up I forget, you want the screen that says start at the top and has device info at the bottom left.)
Connect to computer then go into the platform-tools folder in the SDK folder, hold shift and right click over the window>open command prompt here.
Type fastboot devices and hit enter. Does it show a serial number or does it show nothing? (waiting for device or something like that) If nothing you should uninstall all drivers for the tablet in device manager and install the google usb driver from the sdk manager in the sdk you installed.
Once you see the serial number you're almost done. If your bootloader is locked type fastboot oem unlock
Now from the factory image copy the image-razor.zip, bootloader.img and flash-all.bat to the platform-tools folder.
Double click flash-all.bat
That's it.
I think that it will be beneficial for you to look into using virtual machines (VM's). It allows you to run different operating systems directly from your computer.
The second half to this equation is learning to use Linux (Ubuntu is my choice). Since Android is built from Linux, you don't need special drivers to recognize your devices.
Another option to run Ubuntu is to create a Virtual Hard Drive on your PC, and install Ubuntu onto it (YouTube it, and follow the directions carefully).
Lastly, you can always get a flash drive that is 8gb or greater (16gb or 32gb is recommended), and install Ubuntu onto it was well. It will move little slower than your PC, but your issues will be solved and manageable.
Why am I advocating for Ubuntu? Because it works. PM me if your are interested in learning more, but don't expect me to do all of the work. You need to educate yourself a bit to actually follow my instructions.

First off, let me explain that this device is almost impossible to destroy by flashing the wrong rom. Your over reacting due to inexperience, your Nexus is fine as long as you can boot into Fastboot. When the device is powered down, press the power button and the Volume down key for about 30 seconds, if you can boot into Fastboot, your device is just fine.. Nexus devices are extremely hard to hard brick.. RELAX and realize this is a good time to learn something new, this device is the perfect device to experiment with... You seem to not have the patients and you just need to relax watch a few youtube videos.. No one is going to do it for you.. About 5 years ago I was in the same place you are right now, and I took the time to figure how to fix what ever I did to mess it up.. Its not hard once you realize what your doing. The Toolkit is a swiss army knife of tools that can fix, repair and flash stock roms. Did you unlock the bootloader? Take a breather, give it some time and figure it out like we all did at one time or another, none of us here had our hands held during the learning process with Android devices..
Edit: I'm almost sure you did not unlock your device, to know for sure if your device is unlocked you would see a small padlock that appears to be in the unlocked position at the bottom of your screen while powering on.. If you power your Nexus on, and you DO NOT see a unlocked symbol at the bottom of your screen, you DID NOT unlock your device, thus meaning you have to unlock it to flash it properly.. There are dozens of people in this forum right now that would be more than happy to buy your device cheap and fix it themselves.. If they can do it, you can too..
^Yeah like my last post, those are perfectly fine instructions. If that don't work, stuck at "erasing user data" or something you're ****ed. Most likely.Try a different cord/usb 2.0/computer
Tried a few things. Got any other ideas?

Thank you for your reply. Do you have any suggestions though for my situation? My bootloader was unlocked. I did try locking it then unlocking it several times though. I've tried two seperate stock ROMs, different usb cables, different usb ports, and it now tells me that fastboot is not working. even a link is greatly appreciated. I think it is a driver problem. My tablet does boot into the OS though. I can use the ui for about 10 seconds, then a notification pops up mid-screen: "unfortunately, the process android.process.acore has stopped." Please, even a link is greatly appreciated. I've tried just about everything to get these drivers working, and to get this tablet working. I will continue to research as well. Wish me luck!
Wug's tool has been invaluable to me in the past. I have gone from KitKat to Lollipop, back and forth, different ROMS, stuck boots, bad flashes. Like Zap says if you can get it to Bootloader then get Wug's tool to connect in fastboot, it will do the rest.
A couple times I have ran into problems where my computer has not seen my Nexus 5 because of the drivers, just google nexus usb drivers and install the latest ones.

Got any ideas on Fastboot.exe stopping working when the flash process begins? it fails sending bootloader and then fastboot.exe fails. It says on the screen when i close the error message it's booting into bootloader, but the tablet never restarts. it stays on bootloader(where i had it in the first place.) It should turn off the screen and go back into bootloader. Please, any feedback is appreciated.
Have you tried selecting the option of hardbrick on the tool?
