I am sorry if this topic is covered in other threads. I search around and could only find the developer thread and I am not yet allowed to post there.
--------------------------------------------------------------
I have a new Nexus 7 running Jelly Bean 4.2.1. I have activated developer mode and checked the "USB Debugging" box. Other than that, it is in the default configuration.
I want to root it, so I went to http://forum.xda-developers.com/showthread.php?t=1809195 and downloaded the Google Nexus Toolkit.
After identifying my device (Android 4.2.1 (Build JPP40D) for Wi-Fi Only 32GB), the first option was the install drivers. I did that. The 2nd step was to backup the device and I did that with no problems.
The 3rd step was to Unlock the Bootloader (requires Fastboot Mode). When I try to do this, it says that a Fastboot Device was not found.
I am at a loss here as to what to do?
I have some screencaps. I hope this helps.
Ideas?

TY, this says I need to be able to use "adb and fastboot". That is the problem. I do NOT know anything about fastboot. I turn off my nexus and then hold the volume up and volume down buttons then turn it on. I get a screen that looks like the image I have attached.
However, I do not know what to do from here. I press the volume up and down keys to change "Start" other options, but Fastboot is not one of the options.
Ideas?
You don't have the right drivers installed. When you see the boot loader screen, you should see 'android fast boot interface' or similar in your device manager.

Unfortunatly no one will help you here, they will just give you links to docs you have already read.
Keep clicking OK a few times, it might find it.
if not, then, press the volume down button until it says reboot bootloader or reboot recovery, sorry i can not remember 100% right now,
press ok a few times more, well keep pressing it and it will find it

You are replying to a post from December 16th. Doubtful that the OP is still waiting on an answer.
Nice pot shot at people that do try to help, though. Either that or an unmet entitlement issue. No one in here is entitled to an answer for anything. Anything you or others provide in response to an inquiry is a gift, plain and simple. The answers might even be completely wrong or crap; but they are still a gift.
If the OP is still waiting, then they should know that all the detail that they showed (screenshots) are immaterial as they were taken with the device booted into the OS (composite ADB + MTP/PTP showing in Device Manager) instead of the mode that was having communication difficulties - fastboot/bootloader mode.
Immaterial information does not imply that the wrong driver is installed for a different operating mode for which similar information was not provided.
Most of the trouble in these types of post are due to the fact that the posters have no clue how WINDOWS drivers are managed/installed/ etc. That has everything to do with WINDOWS and user skills, and almost nothing to do with the device on the other end of the cable.
Having said that, the principal reason there is confusion is due to the following set of circumstances:
- Casual Windows users are "accustomed to" doing a single install of a driver package when they buy a new device. Even when that device might have many logical endpoints across the USB bus. (Think of a multi-function printer - it might have an SD card slot on it, the printer, a scanner function, etc). When that multifunction behavior exists, usually the OEM provides a "driver installer" package which will actually install multiple drivers, depending on the plurality of USB endpoints in the device.
- Unfortunately, if you carefully inspect any of these three driver bundles:
- Google (SDK) USB Driver
- Asus Nexus 7 USB Driver
- XDA "Universal Naked Driver"
you will find that (as shipped) NONE OF THEM will work for all of the following modes of the Nexus 7:
- Fastboot mode
- ADB Mode, OS (Single or Composite)
- ADB Mode, Custom Recovery
- APX Mode
- PTP Mode*
- MTP Mode*
That's right. As shipped NONE OF THEM will handle all of these cases. The "as shipped" part is a reference to the fact that a trivial edit of the "android_winusb.inf" file for any of them will allow a single driver to handle all fastboot and ADB modes.*
* The MTP/PTP drivers are meant to be handled by MS Windows generic class drivers; in the case of Windows XP you might need to install a Windows Media package to get the MTP driver - I'm not sure that it is part of Vanilla XP SP3
So, anyhow - people get confused because they "install the driver" for one mode (usually ADB), and then are surprised when they boot the device into a different mode (fastboot or ADB running under custom recovery) and surprise, surprise - their PC says "unknown device".
My advice?
Install the Asus Nexus 7 Driver for everything but the Custom Recovery ADB mode, and then install the Universal Naked Driver for that.
Or, prior to installation fix up the android_winusb.inf file that comes with the Asus driver so that it also supports
%GoogleNexus7ADBInterface% = USB_Install, USB\VID_18D1&PID_D001
%GoogleNexus7ADBInterface% = USB_Install, USB\VID_18D1&PID_D001&REV_9999
Then a single driver will support everything but APX, MTP, and PTP. The latter two of which are provided by Mister$oftie, and the first of which is currently of unknown value to Nexus 7 rooters.
cheers
That is actually a nice clear description, worthy of a wikipedia entry Seriously though the driver situation with Android gives me the sh17s sometimes.

Neither Linux nor OS/X require any drivers to use either ADB or fastboot.
It's a Windows problem, not an Android problem.

I am a Mac user, and I'm having problems with fastboot. My nexus is unlocked, and I'm trying to flash the lastest 5.1 factory image. I was rooted long ago, but really have no need for root, and lost it during one of the OTA's. I'm not a noob by any means, but none of my terminal commands are working, because fastboot has decided to disappear on me. Any suggestions would be appreciated.
I can't even get TWRP because I don't have root, and I can't get into fastboot.
Edit.....I'm an idiot....I figured it out. On top of it all, my USB cable sucks too so that didn't help any.
I'm Italian, sorry for my English.
A few days ago I unlocked the bootloader via Toolkit, rooted and flashed the TWRP recovery _.
But I had hard difficulty:
After driver installed, I unlocked bootloader, enable debugging and then NOTHING!
In practice, the N7 was recognized by windows 7 64bit only in FastReboot mode ..
I tried in every way possible, deleted and reinstalled the driver 50 times, restored windows to a previous point, installed the drivers manually tried without toolkit, but how ADB just do not want to know.
For hours I was still with the bootloader unlocked but without root, until came to my rescue a friend with another notebook but same windows 7 64. Load the Toolkit, install the drivers and everything goes perfectly, I do everything in 5 minutes.
On my laptop there is always the issue driver ADB, in the future I still need my PC recognized the N7 in ADB, how can I do?
One thing that I think is not well understood is that there is no "Generic Class Driver" for ADB nor for fastboot...
... even though the very driver that works for one mode (or phone/tablet device) may be perfectly fine with a different device. The wire protocol for both fastboot and adb are extremely simplistic.
So, what that means is that if the Hardware ID used by the USB device endpoint registers on the bus with a different VendorID/ProductID, Windows will (correctly) not use a previously-installed ADB driver, or previously installed fastboot driver - even though they would probably work just fine.
Here is an example. The Nexus 7 registers the following Hardware ID when ADB debugging is turned on in the OS:
USB\VID_18D1&PID_4E42&REV_9999&MI_01
USB\VID_18D1&PID_4E42&MI_01
On the other hand, if you are using TWRP, it's adbd daemon shows up on the PC as:
USB\VID_18D1&PID_D001&REV_9999
USB\VID_18D1&PID_D001
This means that you might need to install a different driver for using the ADB with the OS, and a different driver for ADB under TWRP - even though it is exactly the same hardware on the other end of the cable! In the absence of a generic class driver for a given USB endpoint, Windows tries to match drivers in it's local (& internet) database based on this VID/PID pair.
If you have a look at the [ADB/FB/APX Driver] Universal Naked Driver 0.72 thread - and download it and have a look at it's included "android_winusb.inf" file - you will see literally hundred of different VID/PID pairs in the driver's android_winusb.inf file in the installer package, corresponding to many hundreds of phones/tablets. Same driver with hundreds of devices listed as compatible.
In the past I recall taking the Google (SDK) USB driver, and manually editing into place matching VID/PID pairs for a HTC phone into the .inf file. It worked perfectly; I probably flashed that phone hundreds if not thousands of times using the Google Driver (My PC is a Windows 7 Pro x64 machine btw).
Anyhow, I have pulled this stunt twice now - once editing the .inf file for the Google Driver, and I did it once with the Universal Naked driver too. You can choose which driver you want to start with.
If you want to give it a roll, you can start with any of those three drivers:
- Google (SDK) USB driver
- XDA "Universal Naked" driver
- Asus Nexus 7 USB Driver (Look under Download)
Note that since you are using W7 x64, make sure that you add each new entries to the .inf file twice - once in the ".NTx86" section, and duplicated again in the ".NTamd64" section. When editing .INF files, make sure to use an editor which preserves simple text file formatting - use "notepad", not "wordpad"
If you want a reference for what values to use, see the bottom end of this post. You should see exactly these same values in your Device Manager, however.
Note that if you see the device show up in the Device Manager as being correctly identified and marked as "working normally" - but it doesn't work - you should probably remove that driver and re-install from a different driver package.
This would certainly be the case for any drivers you saw associating with VID/PID pairs that look like:
VID_18D1&PID_4E40 bootloader/fastboot
VID_18D1&PID_4E41 single adb
VID_18D1&PID_4E42*&MI_01 composite adb
VID_0955&PID_7330 avx mode
VID_18D1&PID_D001 adb in TWRP (maybe CWM too, I didn't check)
That's a lot to throw at you, especially with Italian <=> English in the mix.
Feel free to ask questions.

Hello,
I tried to follow your advice but I have not solved.
I'll explain what I did, so you can correct me.
-Uninstalled previous drivers (from device manager, control panel)
-Restart the PC
-Modified the inf file. Package Asus Nexus 7 USB driver (ntx86 and NTamd64 sections) attach screenshots
-Linked N7 (usb debugging actived)
-Found portable device in device manager, update drivers manually from the Nexus 7 Asus USB drivers
I tried to change also too XDA "Universal Naked" driver by following the same procedure.
I tried to create another account on my pc, but no ADB!

Did you update to 4.2.2?
The is something to do with adb in that update, needing a password or something. I am not sure but if you did update you might want to check that.

Use "Google USB drivers" you get after you install from here http://developer.android.com/sdk/index.html
Its drivers work with 4.2.2
I got 4.2.2. rooted with ADB working now via only this and no other method
No problem with adb in 4.2.2... I tested yesterday (no need psw too...)

Is this the only device which shows up in the device manager? The "Portable Device" is either the MTP or PTP endpoint - not ADB. The latter (adb) should show up elsewhere in the device manager.
You should certainly NOT be trying to install fastboot/adb driver on MTP/PTP endpoints!
I think perhaps I am not understanding because I am guessing at certain details.
Q1) Do the drivers appear to install correctly?
Q2) When you have the N7 in the corresponding mode - whether or not you observe (device manager) "working normally" or "unknown device" - do you see the following Hardware IDs showing up in the device manager?
Bootloader Fastboot Mode:
USB\VID_18D1&PID_4E40&REV_0000
USB\VID_18D1&PID_4E40
OS adb:
USB\VID_18D1&PID_4E42&REV_9999&MI_01
USB\VID_18D1&PID_4E42&MI_01
TWRP adb (Possibly also CWM adb, I haven't checked it) :
USB\VID_18D1&PID_D001&REV_9999
USB\VID_18D1&PID_D001
Q3) I presume you went through the same install sequence on your PC that succeeded on the other laptop - in the event the problem is a hardware problem, did you try a different cable or USB port on your PC?
Q4) When you remove drivers, are you requesting that the drivers be removed from the PC?
The 4.2.2 authentication issue might be an issue (although I suspect this is a adb program version issue, not a driver version issue. In any event, it wouldn't effect the behavior of adb in TWRP/CWM.
Sorry for all the questions.

When the drivers are not installed and I connect to pc N7, is only recognized as a portable device, then later recognized as Google Nexus 7.
To install the drivers (modified as described) I click reinstall driver, then later recognized (if connected to pc in android mode, with usb debugging actived) as Android Device in another voice, ADB interface. But is not recognized by the toolkit under adb devices, and even when I try using cmd.
1-When I install the drivers. seem to be installed correctly.
2-Sorry, where can I find Hardware IDs in Device Manager? What is the difference between OS adb and TRWP adb?
3 - In other pc (with same N7, same cable, same driver, same toolkit) I had no problems. I tried to change only the USB port.
4-I uninstall the driver from device manager (uninstall voice) and ask to be also uninstalled software from the PC
In some Italian forum, I found people with the same problems.
Solved by formatting PC. I would not do that ...
Thanks for your help, sorry for my English and my limited skills

I tried sdk but I have not solved.
I use Android 4.2.1. I'm having problems with the update! I can not update OTA (N7 stuck under the impending reboot). I also tried to download the zip file to upgrade the memory and flash it from recovery but the installation is not completed (error 7 build.prop).
I also tried to flash the factory image 4.2.1 (keeping userdata) and start again. Nothing, same mistakes!
Too many problems!

(Note I attached some pictures below)
From the Device Manager:
- Select the Device in question by right-clicking. Choose "Properties"
- A window with three tabs will appear: General, Driver, and Details. Select Details
- The "Property" combo-box-selector has 20 or 30 items - the 2nd one in the list is Hardware Ids. I attached two pictures from Win7-Pro-x64 (below)
But note as I said before: You should NOT be seeing the ADB endpoint under "Portable Devices" - if ADB Debugging is turned on in the OS, you should see it under "Android Phone" or something similar. In any event, the hardware Ids will identify it exactly

Well, as far as the behavior of the USB driver on the PC, almost nothing. Unfortunately - for better or for worse - both TeamWin (TWRP) and CWM authors put their ADB interface on the bus with the VID/PID pair of USB\VID_18D1&PID_D001, whereas the OS puts all its USB interfaces on 18D1/4Exx.
So, even if you get a driver installed for the OS "adb" mode (say by using the Google SDK USB driver or the Asus Nexus 7 driver), it won't work for the custom recovery... unless you fix up the driver installer package to have the matching VID/PID pairs (18D1/D001) in the .INF file for that driver.
I think folks find this confusing - they think, "wait, I have a ADB driver installed" - why does it not work?
OK, there are a couple more things to try (at least before I give up). Roughly they try to answer these questions:
Q1) Is this a toolkit issue, or a driver issue?
Q2) Is it a prior driver you installed that you are not observing that is causing the problem?
The first one (Q1) is easiest to diagnose: when your PC Device Manager indicates that a device is "working normally" - AND THE VID/PID ID MATCHES WHAT YOU SHOULD EXPECT FOR THE MODE THE TABLET IS IN (regular OS, recovery boot, fastboot mode), can you communicate with the device from the Windows command line? e.g.,
Code:
C:\foo> cd C:\blahblah\sdk-platform-tools-directory
C:\blahblah\sdk-platform-tools-directory> fastboot devices
or
C:\blahblah\sdk-platform-tools-directory> adb devices
If you can communicate with the tablet from the command line - your device ID will be printed by the above commands, then you don't have a driver problem at all - there is something screwy about the way your toolkit is installed.
OK, Q2 -
When Windows installs a driver, it caches it into a kind of database. I suppose it is possible that a prior driver installation might be causing trouble. You can observe - from the device manager - all the drivers that are installed - even for devices that are not currently connected to your computer.
This is done by setting the "devmgr_show_nonpresent_devices=1" environment variable. It can be done semi-permanently this way, or for a single invocation of the device manager this way..
See the third image attached (devmgr-all-devices.jpg ) - it is my computer in that "show all devices" mode. See all that rubbish in there? It's from other Android devices (HTC, Samsung, etc).
You can walk through each one of those - even the devices that are not currently attached - and inspect the VID/PID pair to see if they happen to match the values that you are expecting to see for the different operating modes on the Nexus 7. I'll leave it up to you whether you want to do this or not; it is a bit tedious. Just don't start deleting drivers willy-nilly if you don't know what they are associated with.

ADB driver is installed and "USB Debugging" turned on the Nexus 4. Device shows up on Device Manager, however "adb devices" does not list the device and unable to communicate with the attached device.
The Nexus drive, regardless of MTP or PTP disappears from Windows Explorer when "USB Debugging" is turned on, Turning off "USB Debugging" brings back the drive.
USBView shows the device with a RED light, but it appears working on Device Manager.
I do not have this problem with my other laptop and desktop.

I had sort of the same problem, try uninstalling the driver in device manager, then unplug and replug your USB. Then when you plugged in the USB go to device manager and right click on the device and click scan for hardware changes. See if that works.
I'm not sure if this is a problem caused by windows update or the new updated SDK, but it has been a big problem for me.

OK try right clicking on the the device in device manager and choose update driver, then Browse my computer, then let me pick From a list of devices. After choose have disk on and find the file where your USB drivers are and click next. It may prompt you that windows can't verify the publisher Just click install this driver software anyway.

This is what I did and waited for the PC to install the adb drivers.
I plugged the phone in and with the USB plugged in turned it off while holding the volume up and down keys. This made my nexus 4 go into download mode and the PC automatically installed the adb drivers. After I just unplugged and held the power button to restart the device hope this helped.

When you uninstalled what's there now, you did make sure to check the box that will remove the old drivers from your PC?
Just in case, HERE is another source for the drivers.

Thanks to everyone for their help.
Just to confirm I have already tried:
Uninstalling the ADB driver via Device Manager and selecting "Delete the driver software for this device" and rebooting.
After reboot, Windows could not locate any drivers and I manually selected the drivers found inside the SDK (08/27/2012,7.0.0000)
The device shows up on Device Manager as working but does not work with adb commands. However, fastboot commands work!
I tried the above with the Naked Driver and had the exact result.
If I boot into the bootloader, I am able to run fastboot commands perfectly!
I have already ruled out my USB port as it works perfectly on VMware.
I am thinking my Windows 7 is messed up somehow and re-installation is looking like the only solution :crying:

Thanks. I tried version 16.01 and still have this problem.
The problem is whenever I uninstall/install the ADB driver or disconnect/reconnect the USB, **ONLY** the "Nexus 4" appears on the Device Manager which I manually install the ADB drivers to. There is not a second "Nexus 4" on the Device Manager for the MTP or PTP.
On my laptop when I remove all drivers and reconnect the USB cable, I always see 2 "Nexus 4" listed on Device Manager. One for the ADB interface and the other for the MTP or PTP.
Please help!
Any ideas please?
Any Solution to ADB connection problems?
Hi was there any solution to this, as I seem to have the same issue.
I have tried different drivers and MTP & PPP modes as well as loading the PDAnet drivers and software.
Each time now I take care to remove all the drivers and also delete the drivers in all modes (Android running and Bootloader running)!
MTP & PPP load different copies of the drivers.
I can get either "Nexus 4" showing up in the device driver or "Google ADB Interface" or Android ADB interface" according to the driver loaded.
I can see the device when Android is running ie "ABD Devices" gives me the serial number and connected, then I can send an ADB command "adb Reboot-bootloader" the Nexus then reboots into the bootloader screen, the device driver changes to the bootloader driver (installs if not installed) however then I loose connection to the Nexus phone! "ADB Devices" returns none connected.:fingers-crossed:
I also tried unplugging and plugging back in the phone in bootloader mode but do not get adb to see the handset or it to react to commands.
I'm just about ready to try a toolkit to see if I can get past this roadblock!!!
Current computer is Win7-x64
This weekend I will try on a different computer.....Win8-X64
All comments appreciated
That's because you cant use adb when in boot loader. You use fastboot

I have same problem on my work laptop DELL when my custom desktop machine works just fine with both Nexus 4 and 7. :/
I am generally good at rooting any android phone. I am having a hard time locating the drivers for the VZW LG G2. I have the zip file from the post on how to root the phone, but I am not sure which file to install.
Any input would be appreciated.
If they aren't auto detected and installed after a reboot with phone plugged in, goto device manager, locate the phone and manually update driver pointing it to the LG folder full of drivers. To get the adb interface working, you may need to be in the internet connection mode with the ethernet option selected. Can't remember if that was the case or not.

I needed to install LG VZW_United_WHQL_v2.11.1 then go to LG website and download drivers from the G2 support page. I couldn't upload the exe file. Restart computer and all went well. I had same issue and struggled to solve.
So I figured out how to install the drivers but when I go to command prompt and type"adb devices" it does not recognize it as a command.

You must have the sdk with adb installed before you do that part. Browse to that directory, find adb, shift right click, open command prompt here. Then do 'adb devices'. You'll see serial # on left and 'device' on right. It's working then. If you get 'offline' on right, you need to update your adb.
i'm having the same issue. i'm trying to root, and it won't list it at all, and i'm not getting the debugging icon on top. no serial number popping up on the abd devices and i just tried with both 3.8 and 3.10 drivers. anything?
If I remember correctly I had to go to settings>pc connection>select USB connection method and then choose Internet connection, then choose modem in order to get the debugging icon to appear.

I'm having trouble with my PC not recognizing my phone at all. It says USB device not recognized. I'm on Windows 7 64bit if that matters.

Most likely it's because you don't have the right drivers installed. Try installing these http://g2-lg.com/download-lg-g2-android-usb-drivers-ver-3-10/.

The drivers aren't working for me so i will link where you can get the drivers from the actual website. Please note: this link is for Tmobile D801 but you can search for your device on there.
http://www.lg.com/us/support-mobile/lg-D801
LG's website has drivers for D800 and D801. I'm looking for D802 drivers. Where can I find them or which are compatible?
The Universal device drivers aren't universal?

Where can I find Universal drivers? Not on LGs website.
I installed this:
http://forum.xda-developers.com/showthread.php?t=1379875
And after that it worked fine. I have a ls980, so the att and t-mobile don't work for me. This did.
This took me a while to sort out. There is a certain driver package for the verizon phone. The drivers listed here dont seem to work for me. I'm using win 7. Here is what I needed to use, then everything just came together - LG VZW_United_WHQL_v2.11.1
These can be downloaded at LG's site. Make sure you search for drivers pertaining to the model number of your phone.
Hope this helps someone

LG Drivers failing to install
I Install LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1.exe from LG website, it installs and I get a "successful" message from the software package. However, shortly after windows pops up a bubble with "not successful". Details:
Uninedntified Device - No Driver Found
Creative Game Port - Failed
Plug in phone and select “PC Software”, since none of the other options make any sense (USB charge, Media Transfer, Tethering, and Picture Transfer). Sidebar: None of the other options seem to change anything even when tried. "Media Transfer" is the only one that seems to actually install something successfully, but nothing changes with the device list. Back on track: Get a new windows “installing” bubble. Shortly after I get another “not successful” message with the following:
MTP USB Device – Failed
I go to Devices and Printers, select the phone, and look in the properties. Click “update driver” and pick the LG folder in Program Files. It says “driver already installed”.
Rebooting the computer accomplishes nothing.
I’ve tried several full uninstalls.
No matter what I try, if I run “adb devices”, I get “List of Devices Attached” then my prompt back, meaning none found I assume.
Yes I have turned on dev mode on the phone and I get the debugging icon when the USB cable is plugged in. I’m on Win7 64. WTF is wrong with this driver?
Thanks for any help you can give!
Uncheck usb debug? Had this on my htc one x. Maybe helps

Hi All,
After seeming that I'm locked out of my own device for 72 hours, I managed to scour the net and use parts of other tutorials to successfully bypass the "you're device was reset, please log in" loop.
So I should point out I was running a Pure Nexus rom running 6.0 with a custom recovery, you're results may differ but you've got nothing to loose.
Pre Requisite
ADB and Fastboot - You don't need to spend an hour installing the whole kit, just visit http://developer.android.com/sdk/index.html and scroll right down to the section where it says "SDK Tools Only" and click on "installer_r24.4.1-windows.exe"
Once installed the SDK manager will open, now make sure the top 3 are checked which are:
Android SDK Tools
Android SDK Platform-tools
Android SDK Build-tools
And also scroll down in the list to find Google USB Driver
Once all of that is done download the latest Google USB drivers (although the SDK installs USB drivers it still shown an exclamation mark in device manager") http://developer.android.com/sdk/win-usb.html
To install those USB drivers just go into device manager and if you se Nexus 6 under "Other Devices" just right click and click update driver software and then click browse my computer and get it to scan the Google USB driver folder you downloaded.
restart your phone into recovery (Volume Down and Power button)
now again in device manager make sure the Nexus 6 doesn't have a yellow icon identifying there's a problem with drivers or that the nexus 6 is listed in other devices. If either of those are present right click and update drivers > browse from computer and select the Google USB drivers you downloaded previously.
Bypass FRP
With all that confirmed restart your Nexus and leave it on the Welcome screen.
Now, you need to get into platform tools which is located:
C:\Users\YOURUSERNAME\AppData\Local\Android\android-sdk\platform-tools
if you can't see AppData you need to enable hidden files and folders
once in platform tools hold SHIFT and right click any blank space and click "Open command window here"
then type "adb devices" and it should list your nexus under devices, if it doesn't open device manager and check your drivers.
If it does show your nexus execute this command which edited from another source:
"adb shell am start -n com.android.settings/.Settings"
Your nexus will now open the settings menu =] in settings go to "Backup & reset" then click "Factory data reset" (although it says it wipes user data, mine was untouched, I can't say the same for so you may lose some data if you proceed)
your phone will reboot and in my case it opened my custom recovery and executed a script, the phone will restart again and go to boot, hold the power button to force shut down the nexus and boot into recovery mode. In recovery mode flash a ROM, if you don't have a ROM download one on your PC and then connect your Nexus to your PC via USB and copy it over.
Once the ROM is installed you won't get the "you're device was reset" screen.

You left out some key details which are covered in the guide I wrote up a few days ago. Here's the link.

this does not work, because in order to adb devices to populate anything you would of had to enable usb debugging from within the phone, and if you're locked our from FRP, you cant access the settings to turn on the usb debugging
