Bootlooping, ADB not detected, can't enable debugging - Nexus 7 Q&A, Help & Troubleshooting

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

Booting up your freshly flashed stock device...

Wait for your device to finish booting up...
- It may appear to be boot looping; just wait...
- It could take 5-10 minutes; please be patient...
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
didn't meet certain requirements, like the bootloader
or baseband version, then consider enabling 'Force Flash'
mode in the toolkits options menu and trying the
'Flash Stock + Unroot' processs again. Cheers.

​
- 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

Hi, rohanjoshi...
You're actually on the wrong forum... this is the forum for the first generation Nexus 7 (2012). The forum for your second generation Nexus 7 (2013) is located here...

However, looking through your output, it seems the failure to flash is due to the bootloader being locked...

You need to unlock it with...
Code:
fastboot oem unlock

Good luck.

Xoom memory/flash LOCKED ???

Ok i will explain ...
Got my Xoom ROOTED but decided to put it back to stock, so I UNROOTED by flashing my Canadian 3.0 version, boot it up update to the 3.1 OTA and then setup my market, the XOOM FC out alot so i want to try "hacked firmware".
Boot to fastboot to flash CWM recovery, all the flash show completed OK, reboot into recovery to only found out that it's not there ... ok, try factory reset from the Recovery, all good and then the Xoom reboot ... all my data is still there, then try Setting > Private > factory reset ... all OK, but can boot into the Recovery to fully reset ... no problem, i will reflash a different version via Fastboot.
Try the US-Wifi version, all the flash/erase when OK but still at Canadian 3.1 ... then try installing ROM manager, install fine and working (of cause no Root access). Reboot and the ROM manager is gone ...
Look like the Memory of the Xoom somehow is LOCKED?
Anyone have a idea? i'm taking out the battery for 1h now and hope to have some reaction ... but still nada!!!
Help!!! Thanks

When you flashed the stock Canadian images did you relock your bootloader?
If you followed Moto's instructions completely it ends with relocking.
It sounds like you need to unlock again and go from there. You will still get the OTA updates if you are unlocked as long as you are completely stock, if that's what you're worried about.

Yup! Locked up so i can get OTA, since instruction are differences from person to person ... now, no mater if i unlocked it, it's look like the memory locked out ... like i have copy some files over it, and upon shutdown and restart, the file are gone on the Xoom ... it's like your CMOS on your computer only save data when it on power but lost when you shut it down (is there a backup battery on XOOM?)
Thanks
please .... any one?
Start over from scratch. If you want stock U.S. then use the U.S. stock imgs. Make sure that you use no Canadian imgs. If you want Canadian use the Canadian stock imgs. It looks like you flashed the wrong files together. I see people flashing U.S. stock then trying to root with their country imgs and it messes up. Use adb and fastboot flash moto stock imgs again, boot img, recovery img, system, erase cache, etc. Just remember if you use canadian, the you have to root with a Canadian file as well.

Been there, done that the fastboot flash toke all the flash steps but after it's just "like reversed back" to the original one ... i can even ERASE everything with fastboot and the Xoom still boot up with the "old image" is there a "Short or reset button" on the Motherboard? i have toke out the battery for 10h now
Thx
Sounds like you have not changed the files in your tools folder. I use a seperate folder for stock and root. Keeps me from flashing a file wrong. Make sure that is not happening. Did you try and oem unlock and reboot, then go back to fastboot and flash?

Yes, why lock?
Yep if you lock you can't flash. Go in and fastboot OEM unlock. Then you can update.

problem is not if the Xoom is locked or not, i have tried all possibilities so far, but some place they tell to lock it for OTA.
If it is locked you can't load any cwm or custom firmware.

Do you means the bootloader is locked? event "fastboot oem unlock" show successful unlock?
Please elaborate?
I wish there is nvflash that you can use like the Gtablet
Yeah bootloader locked. But if it says unlocked then try a different rom.

I have done all the Fastboot things without luck, bootloader version 1045 if anyone know how this is can be fix?
like i said, all fastboot command response with success ... so only way now is to see how can i short the memory to wipe out and restart ... any idea?
Thx
I will clear something up for you. You absolutely do NOT need to lock the bootloader for a ota.
In fact there really is NO reason to re lock the bootloader unless you are sending it for repairs.
Where over or who ever said to re lock it you should ignore them from now on.

Factory Restore - Archive does not contain... Help.

Hey guys. My brother got himself a Nexus 7 which is his first Android, and he was playing with some tweaks or mods or something and tried flashing via recovery and has messed something up. I have tried using the Toolkits as well as doing it manually with fastboot. I am able to flash a recovery and use that, but lose it after boot (the permanent option doesn't seem to stick). But, when I try to do a factory restore with the google image, it doesnt matter if i'm doig it manual or with the toolkit, the all respond with a "archive does not contain... " boot.sig, recovery.sig, or system.sig. Here is my output:
C:\Google Nexus 7 ToolKit>fastboot-toolkit.exe -w update "C:\Users\monkey\nakasi-

I have also tried pushing a stock rom .zip to the /sdcard and it doesnt seem to make it either.
Feels like internal memory is corrupt. Any thoughts or ideas I can try? Also... should any custom recovery allow adb access? TWRP or CWM Touch don't seem to work.

That's the most progress I can get. System seems to fail though. Tried multiple times.
Another note... If I boot into Recovery and adb push a file to the /sdcard, the transfer looks like it completes, but when I go to flash zip in recovery it gives me an E: Can't mount /sdcard/. Same thing if I go to the mounts and storage option and try to mount /sdcard.
Any ideas guys? Never seen this before.
Extract the zip.You will get another file..extract that...keep extracting all the files till you get system.img, recovery.img, boot.img, etc ..then boot into bootloader and Manually flash all the img files
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img
etc.

The "archive does not contain *.sig" messages are normal. The FAILED messages on sending the system image is disconcerting. Use the platform tools from Google which includes fastboot. http://dl-ssl.google.com/android/repository/platform-tools_r16-windows.zip
There is a .bat file in the factory image archive that you can run to return to stock. If you don't want to run that, at least open it up and manually run the commands in sequence.

Two more thoughts - 1. try updating drivers. 2. verify the sha1 hash of the factory image
Did you try switching to a different usb port? Just a thought is all.
Wow. Can't thank you guys enough. Thought this was toast. I ended up trying all of the above, haha. Even though I had done it several times. I tried multiple computers, multiple factory images, multiple programs, multiple USB ports. But somehow, maybe your encouragement, something helped. I'll watch it and make sure nothing seems fishy, because I don't know how in the world that worked.... but it did. Thank you very much.

Hi there
I was having the same problem but when I try to flash the system.img (or the 'image-nasaki-jop40d.zip file too for that matter) I get the following error:
"error: cannot load 'system.img': Not enough space
I have done ALL the steps found in this guide without any issues until I get to that part
Help please my wife just gave me this N7 for christmas and I can't believe I may have just bricked it!!
My solution
I understand this is an old thread but I came across it when I was having the same issues earlier today.
Oddly, using the USB cable that came with the N7 seemed to fix the multiple "FAILED" I was getting.
Using my Samsung USB cable seemed to cause the issues.
Hope this can be a solution to others that may come by this thread by googling the issue.

You need the bootloader to be unlock. First run the command " fastboot oem unlock " . It works flawlessly after that! Awesome!

Hi!
I bought a second hand nexus 7 rooted. I had a problem with updating os via wifi because it doesn't update. some kind a problem. I tried to do a hard reset hoping I could just restore the device manually but I messed up so I am now stuck with just a google logo and can only access bootloader with start, bootloader, restore and power off option. I don't know what to do. please help me. I am not a tech person but if you can give me a specific instructions, I know i can manage. i saw a lot off post here that they were able to restore their device so I have faith in this site and the members are highly recommended.

Try this website. If you have any question ask me.
You will need to install files one by one.
SImply open flash bat file see what they are doing. and do same but one by one.
Flash bootloader and radio (radio does not appear on all devices, if it's not in your tgz, you don't need it)
fastboot flash bootloader <bootloader file name here>.img
fastboot flash radio <radio file name here>.img
After flashing the bootloader/radio, you need to reboot the bootloader as shown below, don't skip this step!
fastboot reboot-bootloader
Now you can move on to the rest of the files
fastboot flash recovery recovery.img
fastboot flash boot boot.img
fastboot flash system system.img
NEXUS 9 ONLY - flash this as well
fastboot flash vendor vendor.img
If you want to wipe cache and user data (full wipe), flash these
fastboot flash cache cache.img
fastboot flash userdata userdata.img
Finally, just reboot your device, and Android should start up.
fastboot reboot
Similar issue, please help

So as my previous and maybe above msg said i was just about to attempt adb sideload to manually update to lollipop... From the bootloader i entered recovery... My nexus 4 shut down & got stuck @ wild new boot animation for lollipop. I waited 5 minutes while the fantastic yellow, red, blue & green orbs whizzed around, shut my 4 down & now "Android is upgrading... Optimizing app x of 68." How wild is this... But i still have to lock bootloader. Hopefully it doesnt screw anything up... I'll report back asap

Everything You may need to install android 5.0.1
I'm writing this so that you all will not have to go through what I just experienced when trying to flash the android 5.0.1 OTA manual update. Here are some of the errors I've gotten out of and I will give you some tips to get fix these. I always seem to encounter issues that no one else has when flashing, so here we go.
Tip 1
1.)If you are trying to flash 5.0.1 (tip applies to any version) from the google website here: https://developers.google.com/android/nexus/images ....Make sure your computer can handle ".tgz" files. This took me a day and a half to figure out. If you try to download one of the files off this website without the proper software to do so you will simply get a ".tgz" file that you cannot extract the necessary files from.
*The solution is to download winrar from http://www.win-rar.com/predownload.html?&L=0 this website. Once you do and run it the ".tgz" file will become a folder (icon should look like stacked books) and you can proceed to actually follow the instructions on the page where you downloaded the file from. I learned this the hard way.
Tip 2
If you dont really understand how to us the "ADB" tools or "SDK" and everything related sounds like a foreign language to you then watch this video: http://highonandroid.com/android-ro...r-android-in-a-bootloop-with-no-os-using-adb/. It will explain how to copy files to your device while in bootloop. Pay special attention to the part about making sure your drivers are set up correctly. Drivers always get me when I installs. This knowledge will transfer over to downloading any rom or factory image in the future.
Links for Moving files to your device while in recovery:
Here are the appropriate drivers for copying files while in recovery to the nexus 5:
http://downloadandroidrom.com/file/drivers/Android/usb_driver.zip
Here is the fastboot link: http://downloadandroidrom.com/file/tools/fastboot.zip
Tip 3
The way I installed android 5.0.1 was:
1.)I downloaded the file from the google developer website that i pasted at the top
2.)I moved that file to a folder named "root" that i created on my desktop
*In this folder i have chainfire auto root http://autoroot.chainfire.eu/ in case i need to re-root my phone, I have the adb and fastboot.zip folders in my root folder as well.
3.)I moved the folder inside the FASTBOOT folder and extracted the file that i got from the developer website here. Once this is down there is another
3.)I extract the files here. After you extract there should be another folder called "image-hammerhead-lrx22c.zip." I copied those files to the fastboot folder as well so that they are outside of the zip file. I did not remove the zip file once I copied the insides to the outside. Right or wrong this is what I did.
4.)I used the Command prompt to navigate to this directory. Watch the how to copy files video to see how to navigate using the "cd" command
*basically i typed "cd desktop" which means change directory to the desktop. Then i did "cd root"....then "cd fastboot" ...YOUR PATH MAY BE DIFFERENT.
5.)Once i was here i could follow more of the instructions on the developer website. I could run that "flash-all.bat" command to begin flashing the 5.0.1. In order to run this command you literally type "flash-all.bat."
6.)After it finished it said,
archive does not contain 'boot.sig'
archive does not contain 'recovery.sig'
archive does not contain 'system.sig'
helpful links: http://forum.xda-developers.com/showthread.php?t=1992063
This was okay, what you dont want is falures. While 5.0.1 is being installed, if you notice it say failure in the place where everything else is saying "OKAY" you have a problem. One guy on that xda link said:
"Extract the zip.You will get another file..extract that...keep extracting all the files till you get system.img, recovery.img, boot.img, etc ..then boot into bootloader and Manually flash all the img files
fastboot flash boot boot.img
fastboot flash system system.img
fastboot flash recovery recovery.img"
You can type this into cmd and do each one by one and it may work.
7.)YOU MUST MAKE SURE TO EXTRACT THAT SECOND FOLDER inside the developer file! If you don't you will get failures because the program is looking for them. That's why manually installing them may work as well.
8.)IF YOU SEE THE ANDROID WITH NO LOADING BAR UNDERNEATH this does not mean that you are bricked. I thought it did and kept flashing 5.0.1 over and over and over again. Then i just waited a bit and my phone rebooted and i say the glorious dots rotating on my screen. I lived happily ever after.
9.)Once you are finished installing 5.0.1 you will loose root. Run that chainfire auto root program.You have to boot in to the bootloader screen...NOT RECOVERY...just the screen where you see the android and you can select "start" "recovery" etc. and open up that chainfire program and hit a key to start it. There are instructions on the actual program if you need help. If you are on the bootloader screen that i am talking about and you start the program it will "auto root" that is, automatically root your phone and thats that.
10.)Download root checker off the play store to see if you are actually rooted and have a blessed day. https://play.google.com/store/apps/details?id=com.joeykrim.rootcheck&hl=en
Let me know if you need further explanation. I'm no pro but I've failed in soooo many ways i probably could help ya out! Jesus loves you all!

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:

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.

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:

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.

[Q] nexus 10 Bootloop - CWM exits in 30 secs or so `

Hi,
I recently got a nexus 10, and started working on rooting. I have unlocked it, installed CWM recovery and booted it twice. I have not rooted it yet. Now I realized, that everytime I entered the CWM recovery mode, it automatically reboots back into recovery or normal boot in about 30 seconds or so. (this is not the main problem!)
But one booting up second time, I got a notification of sytem update for 4.2 jellybean (please note initially the device was on 4.2 JB JVP15P), I clicked on install, it booted into CWM recovery, but then it failed to continue with installation, as it complained about authentication failure for the zip fle or something of that sort. So I chose to boot the device without installing the update, now it entered a boot loop. I have tried erasing cache and userdata (both using fastboot commandline, and options in the CWM - in the 30 secs I get). It did not work.
After trying it for a few times, I tried restoring some backups I had made. Initially it complained about MD5 mismatch, and then later on it complained about unable to mount cache/* and unable to mount sdcard.
I have read around and the universal solution seems to be to restore stock images. Is that the solution for me as well?
Any help would be greatly appreciated, and I am noob in this area, so pardon me if I act like one.
cheers,
brickin
I'd like to know part of the answer to this as well. The tab is running fine and TWRP works fine, but CWM constantly reboots and I have the same mounting problems within both CWM and TWRP. I've tried flashing stock image and recovery but it's made no difference.
IIRC, the newest CWM has an issue with devices that allow multiple users (aka: N7 and N10). Flash TWRP and don't look back.

Hi Blueback22,
Thanks a lot for your reply.
Would flashing TWRP solve everything? And also is it ok to flash TWRP now, would it be able to restore the backups I have made using CWM?
Do I need to uninstall or remove the CWM recovery image that has alreday been flashed? or will TWRP image overwrite it?
How do I solve the bootloop issue?
I am unable to get a stock image for JB version: JVP15P. Do you know where I can find the factory image for that?
OR is it ok for me to flash the JOP40C image? Would it cause any problems - (like would it cry saying checksum mismatch or something like that)?
Also, what is the solution for unable to mount sdcard problem?
Sorry for asking so many questions, but I do not wish to brick my device, hence I wish to understand what I am going to do, and ensure that it is not going to harm my device.
Your replies to this post is and will be deeply appreciated.
Thanks,
brickin

If I were you, I would use WugFresh's toolkit to flash back to stock. Then I'd flash TWRP and start from scratch.
I don't know if TWRP will fix your issue all together, but I do remember hearing that there's an issue with CWM on the N10 right now.
Your CWM backups won't work on TWRP IIRC.
Here is where you can get stock images:

Hi Blueback22,
Thanks for the help. I was able to fix the problem.
Here are the questions I had and the answers I found, please correct me if I am wrong.
1. My JB version is JVP15P, is it ok to flash JOP40C stock recovery image?
ans: yes
2. Does TWRP work perfectly with nexus 10?
ans: Atleast in my case it did, I was able to root my device, and was also able to take backups.
3. a. CWM complains E: Can't mound /sdcard !
b. CWM Keeps restarting within 30 secs or so !
c. My device is stuck in bootloop !
ans: First, try to wipe your cache, and userdata and reboot. If it does not solve, then flash stock factory image for your device and flash TWRP recovery image.
4. CWM complains E: can't mount /cache/*
ans: Wipe your cache, userdata and reboot.
Reiterating blueback22's point:
DO NOT USE CWM WITH NEXUS 10. USE TWRP INSTEAD.

Can you get into the boot loader and flash TWRP to see if that fixes it?

Why don't you try cwm 6.0.2.3? I also loaded 6.0.1.9 and it would reboot in about 30sec time. After going to the latest, cwm has been stable. No more random reboots.

For OP and other N10 users with stock 4.2 JB Build JVP15P experience:
Is it possible to use the available toolkits (Wug's or mskip's) to unlock the bootloader and root a N10 with the configuration above? Both toolkits ask for Build JOP40C. I've searched the developer forum for this build and found nothing. Thanks!

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!

Yep, straight from the Angler section. I've tried the latest one, as well as a few older ones. Nothing.

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.

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!
