Well, since you are unlocked, now you will need to download TWRP and put it in you fastboot folder (you need to know how to flash in a command prompt and have the files in the right place:
http://forum.xda-developers.com/showthread.php?t=2277112
after you put the recovery image in your fastboot folder, you type this in a command window (while in the right directory):
fastboot flash recovery recovery.img
(recovery.img = "name of your recovery file.img")
Then you will have TWRP installed. From there, you can either use the toolkit and move files over to flash a Rom or use command prompt commands to move the files to your device memory or just flash the Rom using fastboot commands (it tells you how in the tutorial I linked to.)
The rest is easy. Surf in TWRP and flash away.

Glad it worked out for you.
When you get used to using the commands and understand how they work it becomes really easy to do things you want.
Don't forget to hit the thanks button when someone helps you. It's really the only way people get "paid" for helping everyone out.

This guide will help you unlock your bootloader, flash a factory image, and return you to a stock device. It is wriiten assuming you have a windows PC (MAC users, see post 2). This can be helpful if you need to RMA your device or if you are getting erratic behavior or messed something up.
Tools and Files You’ll Need
If you don’t have adb and fastboot installed on your PC go here for a quick install of the necessary files, thanks to @Snoop05, http://forum.xda-developers.com/showthread.php?t=2588979
For MAC users go here. http://forum.xda-developers.com/showthread.php?p=32305619
For Linux users, http://forum.xda-developers.com/showthread.php?p=10746225
For the factory image go here, https://developers.google.com/android/nexus/images You’ll download a .tgz file. Use winrar or 7-zip to extract the file to its own directory and remember where that directory is. Inside is another zip file, extract that too. You’ll need those image files if you use the long method to install the factory image. It’s also good to know where they are as they come in handy as you get more familiar with fastboot and what you can do with it.
How To Unlock the Bootloader
If you don’t have developer options enabled on your device go to settings, about device and tap on the build number 7 times.
In settings, developer options enable oem unlock
Now you get to use fastboot! Boot you device into the bootloader, vol up + power with your device shut off. Once booted into the bootloader connect it to your PC with the usb cable and open a command window on your PC. Once connected type the following command in the cmd window:
fastboot devices (Your device serial number should show up and this will ensure fastboot is working properly)
Then type:
fastboot oem unlock (This will unlock the bootloader and you’re now good to go)
NOTE, UNLOCKING THE BOOTLOADER DOES WIPE YOUR DEVICE SO BACKUP OFF YOUR DEVICE FIRST
How To Flash the Factory Image, SHORT METHOD
Open a command window on your PC in the same directory as you extracted the factory image. In that directory shift, right click in an open area and use “Open a command window here”
Boot your device into the bootloader and connect it to your PC. Then simply double click on the flash-all batch file. Note that there are batch files in there that will work for Windows as well as Linux machines
Let the batch file run and when it’s done you’ll be back to stock.
NOTE THAT FLASHING BY THIS METHOD DOES WIPE YOUR DEVICE SO MAKE SURE YOU BACKUP OFF YOUR DEVICE FIRST.
How To Flash the Factory Image, LONG METHOD
In this method each factory image is flashed separately. This should be used if you have problems with the short method and as you get more familiar with fastboot you’ll be able to flash only the images that you need for your specific requirement. For instance, you might want to only flash the stock recovery if you’re trying to take an ota and you’ve installed a custom recovery. The order that you flash the images is not important.
In the folder you extracted the factory image it’s easiest if you re-name the bootloader image file to simply bootloader and radio. Then open a Windows command window in that folder and use the fastboot commands:
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot –w (NOTE, this command does wipe your device. It’s possible to flash the factory image without this command but if you’re going from different revision numbers of android it’s highly recommend to wipe the device)
Now open a Windows command window in the same folder that you extracted the zip file in, the one where you find recovery, system, etc. Then run the fastboot commands:
fastboot flash boot boot.img
fastboot flash cache cache.img
fastboot flash recovery recovery.img
fastboot flash system system.img [Note, flashing system takes a long time, so let it do it's thing]
fastboot flash vendor vendor.img
Congratulations, you’ve now flashed a factory image and learned how to use fastboot!
For MAC users, proceed each fastboot command with a ./ e.g. ./fastboot flash boot boot.img
This should be made a 'sticky'...
An excellent well written tutorial... succinct, clear and to the point.
Far better to use fastboot instead of a toolkit... Everything is more transparent, and you actually gain a better understanding of your device as a result.

Thanks @GedBlake. I would have responded sooner but I had to get home and check my tablet. Actually both work, vol up + power and vol down + power.

It's possible that you need to update your Android SDK to the latest. There was a recent change (within last 6 months) to fastboot to allow flashing these large .img files.

Is it possible to extract the .img from the volantis-lmy47x-factory-3efdc8d4.tgz from https://developers.google.com/android/nexus/images and flash them individually with TWRP (with the exception of recovery.img, which I guess would over-write TWRP)? Can it this be done directly from 5.0.1 or would I need to first upgrade to 5.02?
Hi, I'm Italian so i'm sorry if my english is bad xD what happens if i flash a different kernel? Will i lose my warranty?
If yes, if i flash the factory image, will i have my warranty again?
And, again, sorry for my bad english

No need top apologize. You're English if fine.
There's a lot of discussion and lack of agreement about what affects the warranty on the Nexus 9. HTC says that even unlocking the bootloader "may void the warranty".
My advice would be to do what you want to it, but make sure you understand what you are doing. Ask a lot of questions before you do something you're unsure of.
Unlock your bootloader (if you haven't already). Do not relock bootloader if something goes wrong (this does not solve anything). With an unlocked bootloader, you can recover from almost any problem.
And you can flash the Google factory images anytime you want to return to stock.
I'm sorry there's not a clear answer to your question.

Bootloader has to be unlocked to root, install custom recovery (TWRP). And note that when you unlock bootloader, it will wipe the contents of your SDcard. If you have anything important there, back it up on your PC.

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:

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.

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.

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.

Hello Everyone. I need some help with restoring my shield because I seem to have soft-bricked it. Last week I rooted and installed a custom recovery file and all was well but this past weekend I was messing around with it trying to install the custom rom for full android and I think I accidentally deleted the boot file and the recovery file because all I get is the android on his back with the red triangle. Also, when I try to connect to the unit using fastboot nothing is found but I DO get a hit if I put the unit in stock recovery, it gives me the option to click apply update from adb.
From what I have been reading it sounds like I should be able to sideload the recovery and/or the stock firmware. Can anyone confirm or provide me with instructions on how to get this unit back up and running.
Any help is greatly appreciated
Wow I expected people to jump on this one. I guess I'll just keep messing around with it
Hy, here is the firmware and the instructions:

Thanks but I already looked at those and it only provides details for using fastboot which I am unable to use.. device will only show up when I use the regular recovery method and the only option is apply update from adb.
So, if you perform a adb reboot bootloader command from adb it doesn't reboot into the bootloader?

He can only do this if he can adb into the bootloader, hence my question. The implication appears to be that he can't if I'm reading his comments correctly.

Correct. I can only use sideload at this time. Yesterday I was messing around with it a little more trying to sideload the recovery but I kept getting a message saying "The footer was incorrect" and it would cancel the install. I tried different files to make sure I wasn't dealing with a corrupted zip file but they all gave the same message.
I'm trying to figure out how to sideload the recovery

Hi,

I am in the booting black screen for 5 seconds, as the loading screen tells me, before it reboots. Either way when I call this command right after:
fastboot flash recovery recovery.img
I am getting "waiting for device" print and it never finishes. Before that ADB sees my device. What do I need to do so I can fix this?
Thanks in advance.

https://androidfilehost.com/?w=file...c9cf15e47b9a9c4af6f1239b585792c06c0520ebc3480
I extracted the recovery.img
then I followed this:
https://www.theandroidsoul.com/how-to-install-twrp-recovery-via-fastboot/
But after I type this:
adb reboot bootloader
I am in the booting black screen for 5 seconds, as the loading screen tells me, before it reboots. Either way when I call this command right after:
fastboot flash recovery recovery.img
I am getting "waiting for device" print and it never finishes. Before that ADB sees my device. What do I need to do so I can fix this?
Thanks in advance.

First of all it would be a good start to actually get fastboot mode :laugh: You should actually follow a guide instead of trying to do this by your own. Find a guide for the U (assuming that you have an U). You'll have to install fastboot via miflash or whatever
Thanks the guides I found online all advise to use that fastboot command. That's why I couldn't figure it out. I have A2017U yes. Do you know any guide for this?
I will google more using your miflash keyword. Thanks again
The toolkit can do this for you. Make sure you are 100% stock bootstack, recovery, and system, with everything working, before you attempt to lock your bootloader. Lots of people ignore that warning and brick their phones. I'm not sure if your apps and data survive a lock.
I tried to lock mine via adb and bricked it. Luckily, the RMA people believed me that it was a failed software update and fixed it for me. I wouldn't try to do that again ^^
