Yes, me too. I can't load anything except ADB & Fastboot. I used the Nexus 7 Toolkit to try to update to Kit Kat and now I have a soft bricked device. HELP!!!:crying:

Have you tried using adb shell command prompt to push the files to your device instead of a root toolkit?

Effing toolkits again. When will they be banned for once and for all?

Check out this sticky here, it gives instructions on how to do it and what files are required. Its quite a lengthy guide, but its the safest method. http://forum.xda-developers.com/showthread.php?t=1907796

sorry im just a newbie:angel:

UPDATE: booting failed already gone by flashing cyanogen rom
the problem now is stuck in booting.see the attach picture
what is the meaning of
archive does not contain boot.sig
archive does not contain recovery.sig
archive does not contain system.sig

Got the same problem...I used RTK to flash 4.4 and ended up with a soft bricked N7.
Well initially I haven't been able to update any newer versions of CM. I was stuck on 10.2 nightly. I got a notification that there's an update so I downloaded it and tried installing. I get stuck when my N7 will go into recovery, I'll always get the droid with the red exclamation point and I have to stop the update. But I will always be able to do a system reboot and use the N7. After flashing using the RTK, all I can do is boot into the Bootloader mode. Choice at that point it Recovery, Reboot Recovert, Reboot Bootloader and Power Off. If I choose Recovery nothing happens. So the real choice is only to power off or reboot the bootloader.
I tried using fast boot but the guide I got was asking me to put the tablet in debugging mode (which I can't really do). And I get an error when doing the steps in CMD. I think I wasn't able to properly load the drivers because I am not seeing my device listed with serial number when I run >dab devices.
Kindda stuck and waiting where this thread will lead to as well so I can fix my N7.
Also, when I get the factory image (JWR66V) and run 7-zip on it, I don't see these files: bootloader-grouper-4.23.img, image-nakasi-jwr66y.zip, flash-all.sh, flash-base.sh. I only see 1 file.

As mentioned in about 5 billion threads, USB debugging has nothing to do outside of a booted OS.
Fix your drivers.
Unzip the factory image archive.

^Fixed my drivers (via SDK). PC recognised the device via fast boot devices. Ran a set of commands fast boot erase boot, cache, recovery, system, and user data. Flashed boot loader and reboot boot loader. Flashed 4.3 factory image (extracted via 7zip). Flashing/Update FAILED (I think the error was 'too mani links') and it went back to a blinking cursor.
@niceguy01 - just wait for CMD to process the entire thing. I was worried as well when I saw the system does not contain boot.sig etc error. Waited for it and started getting some scripts after. Wasn't able to complete the flash though but little steps getting there.

where should i flash radio.img?
boot,bootloader,recovery.system or userdata??see the picture
thanks

I'm bricked .. Getting worries. (Yes I've read the forums ...)

Attempted to flash Liquid Jelly Bean, then got stuck on the animation boot screen. I've tried Root tool kit for unbricking and setting it back to stock. Tell me it's successful but stays stuck on the animation screen.
I've also tried to unbrick manually however even though I have the correct files placed in my Platform Tools folder of Android SDK ... I constantly get stuck at the CMD prompt steps. Any time I type in "ADB reboot loader" or ..."fastboot flash bootloader bootloader-grouper-3.34.img" or anything similar I get the error message in CMD saying "___ Is not recognized as an internal or external command"
I'm not sure what to do. The bootloader does say that my device is locked, I just can't get passed the splash screen!

Here's an update:
I think I've made it worse ...
Nothing will boot now and it's currently locked. Any time I hit "Start" it says "Booting Failed"
My CMD now says; Error: Cannot Load "Bootloader Grouper-3.34.img"
I'm seriously lost. I've been working on this for about 6 hours now ....
Can you get into bootloader and then recovery by holding the power and volume down buttons? Was ADB actually working before all of this??

No I can't get into the recovery at all. When I turn on the device I don't even need to use the rocker keys to get into bootloader either. Actually my bootloader is a bit different now too. I have the 'Google' logo and at the top the regular options for Start, Recovery, Power Off, etc.
In simple terms: I can't even get to the animated splash screen anymore
Open the command prompt IN the directly WITH fastboot
Fastboot oem unlock
Then wipe / flash factory images. Fastboot -w update image whatever the image name is.
Then uninstall / delete that stupid toolkit and never use them stupid craps again.
Are you still able to communicate with the device via fastboot? If you issue the command 'fastboot devices' does it return a serial number?
Edit: I'm going to bed so if you are able to use fastboot, download the factory image pack from https://dl.google.com/dl/android/aosp/nakasi-jro03d-factory-e102ba72.tgz
Extract the archive. Inside are there will be an install script, manually issue the commands contained in the script in fastboot. The only thing you need to add is the location of the .img and .zip files from the archive you extracted e.g. 'fastboot flash recovery c:/Users/name/desktop/recovery.IMG'
There is no reason this will not get you up and running again.

Thanks for your response.
I've followed the instructions in the file. From previous research, I've had these files. My device does communicate with Fastboot. When I give the command for Devices it gives me my serial. Also, when I ask it to reboot-bootloader in CMD it does.
My issue is when I get to "Fastboot flash bootloader-grouper-3.34.img". CMD states "Error: Cannot load bootloader-grouper-3.34.img"
I've followed the commands previous to that. (Erase boot, cache, recovery, system, userdata)

Yes my device is unlocked again, but I still can't get into recovery mode. It just tells me "Recovery Failed" in small text in the upper left hand corner of my N7.
UPDATE:
After unlocking the device again. I used the Nexus Root Toolkit to restore to factory settings and it worked
The Problem: My device was no responding correctly to the toolkit when locked.
Cheers for the help. I'll attempt to root again, hopefully no problems this time If there are I'll be sure to post again!

So you erased the recovery then wonder why you could not boot into recovery....
You flashed or tried to flash the bootloader. You already had the same bootloader installed and there was no need to do so to try and fix your issue.
You still don't know what you're doing and are back using the tool that lead you to this issues. A toolkit. Learn what you're doing and you wont face this type of silly issue again.

Don't use toolkits. Most people don't have a clue what the toolkit is actually doing so if something goes wrong they aren't in a good position
Its always nice to see threads like these where the N7 in the face of death but in the end with cutting edge medical technology it is brought back to life and healthy.

bricken N7, no OS installed

i was stuck in a bootloop after flashing a ROM, and didnt have any backups or other ROMs on the devices storage, so i was attempting to push files to it via ADB, but it wouldnt connect. i went back into the custom recovery image, and accidentally wiped the whole thing, so now i have no OS installed, and not even the seeminly 'faulty' ROM in /sdcard either. i can still get into the bootloader and the custom recovery, but cant seem to get it to connect to ADB. any ideas what i can do?
If you could boot into fastmode, then just flash stock rom.

how do i boot into fastmode? all that i can access is the bootloader, and TWRP. when on the bootloader screen it sort of connects to my PC. i can go into device manager, and will see 'android bootloader interface' in there, and i have updated the drivers as per the instructions in the nexus root toolkit, but it wont seem to talk to ADB for some reason.
edit: ok, this is really odd. when i use the NRT to try pushing a zip file, if i start the it trying to push the file, then open a command line and use 'adb usb' NRT will say that it has connected to the device, and goes through its various steps, and ends up booting the device into recovery, but the actual zip it was supossed to have pushed isnt there...
it made it enter twrp, so it must be communicating in some way, but when i type 'adb devices' it doesnt show up...

Stop using the toolkit and read the sticky that's not too far above your post... the one titled, "[GUIDE] Flashing a Factory Image with fastboot / return to stock." Coincidentally, it happens to be exactly what you need.

You don't need ADB if you are in the bootloader- you use fastboot.

Soft brick (Already searched up and down)

So I messed up my Nexus somehow. I was trying to install MIUI coming from Carbon ROM but something went wrong as it got stuck on the miui logo. So I rebooted to TWRP and restored my backup. So then I tried to install PA and then it just got stuck on the google logo. So i restored my backup again and tried again to no avail. Then after that I couldn't restore my backup ( I keep getting FAILED as soon as the data restore starts). I can boot to Recovery but I dunno what to do. I tried sideloading but that's not working. I tried the toolkit but everytime it tries to download the factory image it says 404. The phone charges and whatnot but I don't know what to do. I only have the PA rom on my phone and reinstalling it doesn't do anything. The only weird thing is that when I try to install the PA gapps I get a FAILED message. Any help would be appreciated

Have you tried to install another rom on your nexus?
you can put it on with adb push command from recovery though a pc, and then wipe everything and try to install it.
Or you can download stock 4.2.2 rom here: http://forum.xda-developers.com/showthread.php?t=2147281
Here you can find your factory image directly from google: https://developers.google.com/android/nexus/images#occamjdq39

you must enter into recovery, connect your phone to your pc with usb cable and then you should be able to see your device,
try
Code:
adb devices
on CMD and it can see your phone type
Code:
adb push **your-rom-from-computer** /sdcard/
then just install it from the recovery
When you say recovery do you mean the main menu? I'm using TWRP and when I'm on the main menu my PC doesnt read the device

Ok, wait. I need some clarification. I'm going to try to be as simple as possible, to make sure we are on the same page. When you say your PC doesn't read the device, do you mean through adb or on Windows Explorer?
If you mean through Windows Explorer, then that is not where you need to be. You must get adb working as a bridge to your device. Use this sticky guide to get it set up. I would recommend reading that guide top to bottom anyway, it's extremely informative and new-user friendly. Anyway, the info you need is in the 'Setting up ADB for our device:' section.
If you have adb installed, you need to check to see if it recognizes your device. Do this by opening up cmd and navigating to the folder that adb.exe is located. After that, use 'adb devices' to see if adb recognizes your device. If so, move to the next paragraph. If not, your drivers aren't set up properly for recovery mode. Go into Device Manager on your computer and find your device (under something like 'Other devices', or 'Android device'). If you find it, then get these drivers and install them for the device. Do this by right-clicking, and selecting 'Update Driver Software...', 'Browse my computer for driver software', and browse to that folder. I may have missed a few steps on installing the drivers, it's been a while. If so, just search on how to do it, or post back here. I'm sure I can walk through it and get a more precise guide.
Assuming you have adb installed and it recognizes your device, you need to open up cmd and navigate to the folder that adb.exe is located. Then, use the adb push command as outlined above.

[Q] Boot doesn't go beyond rotating circles. Help!!

I tried to search, but in vain.
Hardware: Nexus 4
Software : Android 4.4.4
For reasons that are not clear to me the machine restarted and is stuck in those 4 rotating circles, and doesnt go beyond it. Tried multiple things such rebooting, rebooting into recovery and booting again, tried adb to see if it can see the machine in recovery mode, but to no avail.
Can someone please help? Thanks in advance.
Did you do anything, flash anything to get the boot loop? Boot loop can usually be cleared by doing a factory reset. But you'll have to reset up your phone afterwards

This is a stock android and have no changes whatsoever except automatic update to 4.4.4. Only thing that is different is it is unlocked.
For last one week the phone kept complaining that it was unable to back up photos and videos. So I kept the wifi on over the night, and next morning I saw what i thought was it was trying to reboot but unable to do.
Is it possible to connect to machine while it is in recovery mode? My ADB can't discover the device either in recovery mode or while it is trying to boot. Is there a way to press some button and hard reset it?

I can get into bootloader - if you mean by pressing down volume button and powering on - so you see a few options such as 'Start', 'Restart Bootloader' et al.'
If I can get into this, what option do I have? How I can I some custom recovery such as TWRP?
Also, I saw a youtube video where a gentleman shows how to completely reset from Recovery mode (hold power button and press up volume key), but that doesn't seem to work for me.

Yes, that's the bootloader. Google 15 second adb install xda and install that. Then download the latest version of this http://techerrata.com/browse/twrp2/mako
Rename it recovery and put it in the same directory as fastboot.exe which will be installed with the 15 second adb install
Open a Windows command prompt in the same directory as fastboot and then with your phone connected to the pc and in the bootloader type the command in the command window
fastboot flash recovery recovery.img
This will instal twrp to your phone

My Biggest concern right now is not TWRP. I need to somehow get the machine to boot. It is stuck in those 4 circling things, and I need to somehow get the OS to work (or re-install if needed).
I am able to get to recovery where I see options to 'apply aupdate from ADB,' 'wipe data' and 'wipe partition'. I have wiped off everything, now I need to somehow get OS to install, and I don't know how. I tried using 'adb sideload 'image-occam-ktu84l.zip', but it fails.That file was extracted from occam-ktu84l-factory-0d3fd624.tgz from Android site.
Update: Great, now TWRP is installed. What next? I don't want CM at this point. Just stock Os. How do I get on to the machine?

Now that I have TWRP, how do I install CM? I would eventually like to return to stock, but at least for now, I need to get the phone going.
UpdateOk, the TWRP wasn't functioning well (swipe function wouldn't work), so got CWM recovery, and installed CM. CM too goes into infinite loop. Now I am completely stuck, I have no idea what else I can do.

I installed both TWRP and CWM alternatively, installed factory images using flash-all.bat, install CM11. But in both cases, 1. factory image : The system get stuck in boot mode where those 4 circles keep rotating around each other, 2. In CM11, the arrow keep rotating indefinitely.
I don't know what else I can do.
Any pointers? Thanks in advance.
I am beginning to suspect hardware malfunction. In which case, is there a log somehow I can see?
As an Aside: 1. Adb refuses to see the device in fastboot mode. Not sure if this is an expected behavior. Fastboot can.
2. Stock Android USB Drivers never work. I had to get the WugFresh Development drivers.
This is Windows 8 environment.

You probably have a failure of the emmc. What happens if you try to lock the bootloader and then reboot? Does it stay locked?

Yes, after locking (fastboot oem lock), bootloader the status says locked and I no longer see that unlocked icon when booting.
- At the moment I have CWM, and I see advanced options to format different folders which I have already done. But what I am not able to do is to use adb to copy the image-occam-ktu84l.zip to sdcard. Only way I have been able to install any zip is using sideload. Is that normal? I wonder if I am following right steps to begin with.
- Also, are there tools that can run and check if emmc has no bad sectors etc?
- In CWM I formatted whole log of folders, and now when CWM boots, it can't find /cache/recovery/* files. Which I take as a good sign - since old stuff is now gone. From here I don't know how to proceed. Any help - very thanful.

If you can side load you should be able to adb push a rom. When in recovery type adb devices. Does it show that your device is connected? Do you get an error?

I can sideload from adb. (adb sideload <filename>.zip while CMW is waiting for abd sideload). But can't push since adb doesn't recognize the device while in fastboot - the way fastboot can.

You have to be in recovery to run adb commands. The bootloader is only for fastboot commands. Try pushing while you're in recovery, not the bootloader.

Here 's what I see when I to sideload,
In CWM, I choose 'install from zip, which takes me to next page where i chose to select from sideload. I then start sideload from 'adb sideload occam-ktu84l-factory-0d3fd624.tgz' (sometime I use the extracted zip from that tgz),
Following is what I see on CMW,
'Restarting adb
Finding update package...
Opening update package...
E: Can't open /tmp/update.zip
(bad)
installation aborted'

Ok, you can't use that file (tgz) in cwm, adb or fastboot. What you can do is extract it and then use the zip file. But, you'll have to boot into the bootloader and then use the command
fastboot update update.zip

Help, bootlooped! Locked bootloader.

Hello!
I have the Nexus 6P and I have successfully rooted 16 phones over the past 4 years and never had a problem I couldn't fix. Today I made a mess of my new phone.
I had a perfectly working custom ROM with an unlocked boot loader with TWRP (2.8.7.2) installed. I installed some custom soft keys and got into a boot loop. I went and flashed what I thought was the stock ROM according to the website I was following, and I re locked my boot loader like a fool and was going to eventually unlock it.... turns out I was still boot looped.
I have tried:
sideloading 3 different zips, always get the message "cannot read zip" whatever the zip is
I tried changing the names, doing the full names, doing a stock rooted zipped ROM, nothing works.
I have used SkipSoft and Wugs toolkit and I can't flash ANYTHING or transfer files onto the phone unless the bootloader is unlocked.
I have installed the Google drivers multiple times, ADB devices always works, it seems to not be a driver issue because I can do everything else fine.
I have let the phone sit for 35 minutes in bootloop waiting for it to come back online so I can tick that "OEM unlock" button in the settings menu.
I have also done a dozen other things, the problem is nothing I have done or tried allows me to get any ROM or any file onto the device to flash in TWRP.
Help?
ok shot in the dark here. I had a boot loop until I flashed the flashable vendors zip
I got it in this thread:
http://forum.xda-developers.com/nexus-6p/development/rom-pure-nexus-layers-fi-wifi-calling-t3244563
Give it a whirl if you haven't already.
Found this in the Pure Nexus Project thread, so props to them for providing this.

Thanks, the problem is I can't find a way to sideload anything or move a file over. Everything results in a myriad of errors.

at worst, you would have to invoke the flash-all command via adb once you extracted the couple of times that you have to. directions are on google's factory image site.
may not be the answer that you were looking for, but it always feels great having a clean device to work with. i mean as it stands, you would have to set everything back up on whatever rom anyway if you somehow got out of the problems you were having. you would spend more time doing that instead of just going the factory image route.
toolkits are fun, but learning your way around them is even more so.

I'm gonna check the flash all,I've never done that before. I think that would be all the images in the tgz factory image? Anything to get my phone back yeah, I just need it working again.
-UPDATE- I tried the flash all batch in the system image and I tried the flash all batch command and neither work.
Hey man - crazy story - I literally just got done messing with a toolkit and the EXACT same situation happened to me. Locked bootloader, bootloop, everything. What you need to do is do a complete wipe of everything in TWRP so you can access /data from your PC (unless it isn't messed up currently, and you can decrypt within TWRP, I couldn't...) Then, download Cataclysm (maybe something else will work, idk, but I just did it with cataclysm) and bam - it boots, head to developer options and get the box checked.
Stock images didn't work, nothing did... was scared I had a brick. The saving grace for us is that we both got TWRP installed. No more toolkits for me!

I have already done the advance wipe and the format data, I just tried again and my computer will not read it as storage with MTP enabled.
Thanks though!

after extracting the tgz file, it should become a tar file. after extracting that tar file, it should become the six files listed below. these files should be in platform-tools to start from scratch.
bootloader-angler-angler-02.45.img
flash-all.bat
flash-all.sh
flash-base.sh
image-angler-mmb29m.zip
radio-angler-angler-02.50.img
once they are, open command line in that directory (platform-tools) and then "flash-all" should work. if it doesn't make sure you post the error that you're getting on your computer so that others can help.

I followed all these steps, I unzipped it and everything and put it in my fastboot folder. I still get the "unknown partition "all" " orrr flash is not recognized as an internal or external command, operable program or batch file. In an attempt with desperation I tried opening every version of the batch file, in the tgz and tar and unzipped AND in the fastboot and it all gives the radio img error.
I still do have my fastboot device connected, to my knowledge that means it can't be a driver problem right?

You can't flash anything in fastboot with a locked bootloader. The only way you can get your device to work is by using TWRP to flash a rom.
The flash all command doesn't work because the extracted tar file has A zipped folder inside that has to be extracted also with radio and I think recovery zipped up. You have to extract those two files to put them in the tar file and then you might be able to flash all. But as long as you can fastboot devices you should be able to flash all 6 files and have a brand new device.
tigercranestyle said:
sorry for the late reply. not always here.
1. did you unlock the bootloader again before doing all of this?
2. list the files that are in your platform-tools folder.
3. when you executed the "flash-all" command earlier, you did do it with the dash in between flash and all... right? also, you're doing it without the quotation marks, right?
sorry if they seem silly. just never really know.

He can't unlock the bootloader without booting into a rom. He needs to use twrp to flash a full system but I am not sure how to help with that when he can't sideload.
just an unrelated question... why did you lock the bootloader again? what was the purpose?
also, as mentioned... locked bootlader, odds arre USB debugging and OEM unlock are also not checked.... afaik, youre in trouble... hopefully someone else can sav you, im out of ideas

Are you telling me that I'm bricked?
I have no way of transfering files to the devices, it won't read as anything to transfer files and ADB won't sideload anything.

Neither am I , I just got back from a trip. I have the fastboot exe adb exe mfastboot exe the ADB api files, and the ROMs I tried to sideload along with all the images I pushed to the device.
Originally I had the bootloader unlocked, like I said I was being a fool blindly following a tutorial to get back to stock and I locked it too soon.
Yeah, I tried flash-all flash all and flash flash-all / flash flash all

Okay I unzipped that folder and put all the files in the fastboot folder, I still get the same error. The thing that scares me here is I can use the batch file now and it just gives me an error saying it can't flash because it's bootloader is locked.

They are default unchecked, hence the reason I can't unlock the bootloader again. I said it in my first post, I was being a fool following some guide to get back to stock and ******* up a step.

Is there not a way to fix the sideload? Or a way to get my computer to read it as a media devices so I can transfer files or something? It's always worked with previous phones but my computer reads the 6P differently. (even when it was working)
Stop trying to fastboot flash anything, it will not work as I've already started multiple times. The only option you have is to get something moved to storage and flash it from twrp.

I've tried every driver from Google and Nexus 6P, I can't get it to read the MTP for a file transfer, what would you suggest I do? it doesn't show up as my old phones used to in the computers drives.
I have found 0 success with getting a file on through file transfer or ADB push file.

So I just got it............!!!!! I have spent a total of 16 hours with videos, forums and trial and error. When I was going back the 5th around time messing with drivers I turned my ADB driver into a USB composite because I had no idea I could and instantly I was able to file transfer!!!! Problem solved, I have my ROM on now.
Thank you all for your help! I am so sorry I derped at this, I have been doing this a long time and just got sloppy.
