I'm currently getting some strange errors while trying to control my N4 over adb.
http://prntscr.com/1km24i
On Ubuntu I get "device unauthorized" and on Windows 8 I get "device offline".
Same thing happens over USB.
Any idea?
PS: I'm currently on 4.2.2. I where on 4.3 yesterday but installed 4.2.2 again after some strange errors.

As the message have stated, you need to allow the adb access on your phone.
You need to first connect the phone to your PC with USB cables, then the authorization message will pop out on the screen. Tick remember your choice, then allow it.

I'm not getting any message.
Maybe because I already authorized my pc before. A few weeks ago adb worked just fine.

Remove /data/misc/adb/adb_key, reboot your phone and try connect again. The message should come up.
Perfect, worked. Thanks!
I just got my phone back from LG (the mainboard "Fried"). I have the new update pushed to the phone. I have to re-root the phone now as its basically a new phone.
I am getting the Device offline as well message in ADB. As I don't have root, how can I fix this error? I can't navigate to that particular directory. I had no authotization message show up on my computer when I plugged the phone in for the first time... so not sure how to get past this...

This shouldn't be happening on new phone, because the key won't be created if you haven't authorized it.
Can you check your adb version? Try updating it with android sdk manager.
I am going to try and re-download the ADB SDK. I think it's an issue with whatever version I downloaded. I've tried to run the ADB Manager.exe and nothing happens. Currently flying to London so it will have to wait until I get back. Nice of LG to fix my phone and they didn't charge me a dime. Although I did lose everything.
Hello,
I'm having the same problem "Please check the confirmation dialog on your device", but there is no such dialog on the device.
Things I tried and DID NOT SOLVE:
1) Remove /data/misc/adb/* - Failed, there was nothing there (full wipe before flash a new rom)
2) Try different ROMs - Failed, tried AOKP Milestone 1 and 2 and CM10. Dialog never showed up.
3) Try different usb cable OR usb port - Failed, adb is recognized, but no confirmation dialog on the device (device shows as unauthorized)
4) Removed all drivers and installed them again - Failed, same problem;
5) Updated android-sdk (or full delete and reinstall [remembering to adb kill-server]) - Failed, problem continues even with platform-tools up-to-date.
6) Removed all folder C:\Users\Myself\.android - Failed, it was never recreated;
7) Tried to connect via adb over wifi, device is found but unauthorized persists;
Things that gave me some clues:
1) Reboot to recovery mode allowed me to use ADB without any authorization (only while in recovery);
2) Recovery sideload works without any problem;
3) HOWEVER, when connecting to another computer (Windows XP, fresh install on a virtual machine), dialog appears and adb works!
The scenario:
1) Devices tried: Galaxy Nexus / Galaxy S3 I9300
2) ROMs tried: AOKP (4.2.2) / CM10 (4.2.2)
3) Windows 7 x64
The problem is on the computer side, that's a fact. However, I would like to SOLVE it without having to reformat my computer, or change my OS.
Where to start?
Thanks!

After removing your .android directories, you need to restart the adb server to send fresh credentials to the phone.
First unplug the phone from your computer, then run:
Code:
$ adb kill-server
$ adb start-server
Now plug your phone back in and you should see a dialog on the device asking to confirm new credentials for your computer.
After confirming the credentials you should be able to connect to your device.
I hope that this helps...

I know that this post is old, but I came across the same problem while attempting to root my Galaxy S4 today. This ended up being the solution:
1. Grant yourself root access on the PC that is running adb
2. Remove RSA Keys:
rm /home/username/.android/*
3. Restart adb server:
adb kill-server
adb start-server
I hope that this helps.
SOLVED!
I guess I should have read the previous post before I posted this but anyway maybe this helps.
I had this happen to my Verizon Samsung Galaxy S4 SCH-I545 running 4.3 (VRUEM2K) after I rooted using saferoot, then removed the SuperSU app using SuperSU's so-called "safely unroot" menu option. It will no longer request the RSA key from the Ubuntu system I previously authorized (and used to root) and won't re-root using saferoot or motochopper. But since I dual-boot Windows 7 (I hardly use it, came with the laptop), I figured I'd give Odin a try and re-flash it to stock which didn't do anything to the "custom" flag and I still got "unauthorized" in adb in Ubuntu, but I noticed it does show up fine with adb in Windows. I tried the windows verison of saferoot and it was able to re-root my phone and re-install SuperSU just fine. Phone still showed "unauthorized" in Ubuntu.
After posting this I saw the previous comment saying to rm -rf ~/.android/ in Ubuntu. I also cleared all previously authorized computers and disable dev mode on my phone, rebooted, turned dev mode back on, rebooted again. Not sure if this helped, but I went through the following steps as root:
[email protected]:~# adb kill-server
[email protected]:~# adb devices
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
List of devices attached
15506b89 unauthorized
At this point I pretty much said "F it, not gonna work" and walked away to get a snack, leaving my phone plugged in. I was only gone a couple minutes and when I came back, the RSA authorization request had popped up on my phone. I checked the box to always allow this computer and authorized it. Then SUCCESS, as seen below:
[email protected]:~# adb devices
List of devices attached
15506b89 device
Removing the .android directory seemed to do it, but you need to wait a few minutes for the computer to re-request the RSA key.
after a week of searching. I NEVER KNEW it pop to accept to authorized. WOW cant believe it... after reading this thread im lol'ding right now.
I had tried to kill adb etc but keep saying aunauthorized. solution was to reboot my phone with usb connected,after boot it the dialog to connect appear and my s4 got authorized. backup success.
thanks to the adb kill-server guy! worked for me

I have searched extensively to no end. When I ./adb devices in terminal, it lists my phone but says 'unauthorized.'
I do not get a prompt on my phone to authorize its connection to osx.
I have rest phone to factory spec. Still nothing.
Thoughts?

I had this issue on a stock rom with ADB in Windows and in Linux. This apparently is a known "issue" with the stock rom when the USB mode is set to MTP.
The "fix" is to make sure you are in Network mode (either Internet or Modem is fine). You might have to disconnect and re-connect the USB cable a couple times (and re-select the Nework mode) before it will actually connect with ADB. If it pops up with the ADB Verify Server Fingerprint window on the phone, you have sucessfully made an ADB connection.
I can't access my N7 with adb (when booted) or fastboot (while in the bootloader). It's connected via a USB cable. This is both with a Mac and WUGS. Commands like fastboot devices or adb devices return nothing as the device isn't seen. I can connect my N4 and use those commands without problem. I just tried doing the same with my 2013 N7 and it's not being seen, either. Strange. I don't think I've had this problem before on the Mac. I have on Windows, which I can sometimes resolve by installing and reinstalling drivers until something works.
I'd wanted to update the 2012 N7 to Lollipop.
Thoughts, anyone?

Crazy as it sounds, try another USB cable. Reboot everything, plug in fresh, and try again. Failing that, use WUGS to reinstall all your USB drivers. Use the stock Google.
The cable was the culprit. I tried another and it worked. Thanks so much!
I'm having a similar problem that's driving me insane.
Nexus 7 wi-fi version
I've loaded every driver on the planet and in recovery mode it simply will not show up. And I'm not talking won't show up using ADB, I get absolutely nothing in device manager. So before anyone tells me to point to the device and manually change the driver, there is no device to try and point a driver to.
In "normal" mode, it shows up perfectly fine in Device Manager as Android ADB Composite Device. ADB will list it in devices with no problem. It will accept the "adv reboot recovery" command perfectly and reboot the tablet into stock recovery. The minute it does that, the device disappears from the Device Manager list and nothing takes it's place. I've tried to have it search for new hardware, I've tried the Google USB drivers kit, I've used Koush's Universal Driver install. I've used 3 different cables on 2 different USB ports.
This is a completely stock N7 running 4.4.4 plugged into a Windows 8.1 64 bit PC.
The last thing I'm wondering is do I have to unlock the bootloader at all? I don't want to because it'll wipe the tablet. If so I guess I'll just wait out the actual OTA rather than try to sideload it.
Any suggestions would be appreciated.

Ummm... does the Stock Recovery actually run "adbd" by default? If it doesn't (or it doesn't start adbd until you execute the sideload menu item), then you wouldn't normally see anything on the other side of the cable with a stock Recovery. (I don't have my tablet with me to check)
Here's an extra "any suggestion at all":
Get rid of Windows and use Linux; there are no drivers to screw with in the latter case.
No, seriously. But probably not what you are thinking.
If you can get a "live CD" to boot** on your PC, you can (as root) run the "lsusb" command to see what devices are enumerated on the USB bus, port by port.
In conjuction with the decoder ring at the end of this post, you can determine from inspection of the USB VID/PID identifiers whether or not all the hardware is behaving, and whether or not the tablet is in the mode you think it is supposed to be in.
The reason this is valuable is that it allows you to take drivers completely off the table; if everything is as it should be, then you know that all the hardware and cabling are functioning correctly, the tablet is behaving correctly, your PC hardware is behaving correctly, and that 100% of the problem is Windows driver issues.
If you want to go the extra 1/4 mile, you can put a copy of (Linux) fastboot & adb plus your flashables on a USB key, and run adb or fastboot from the Live CD boot. It won't matter that the live CD doesn't have them preinstalled, they will be on your USB key. It will be easier on you if you can find statically-linked fastboot and adb binaries; if not you will have to copy one or two supporting shared libs (.so files) along with the binaries, and find out what LD_LIBRARY_PATH is all about.
suppose the USB key mounts at /media/usb1; then
$ sudo /bin/bash
# mkdir /tmp/tools
# cp /media/usb1/fastboot /media/usb1/adb /media/usb1/*.so /tmp/tools/
# chmod 755 /tmp/tools/*
# export LD_LIBRARY_PATH='/lib:/usr/lib:/tmp/tools:.'
# cd /tmp/tools
# ./fastboot devices
OR
# ./adb devices
Good luck; as you are using Windows you are going to need it. Hahaha LOL
**depending on whether your BIOS on your win 8.x PC can be toggled between UEFI and Legacy modes or not, this can be either trivial (Legacy boot mode) or complicated (UEFI) requiring a "Trusted Computing" crypto boot shim from MisterSoftie.
Ok this works for me
Use USBDeview (http://www.nirsoft.net/utils/usb_devices_view.html)
delete all the associated drivers like Google, Samsung, etc for ADB, etc
Restart Computer
Reconnect N7 without MTP and USB debugging
Wait for PC to recognise device and install driver
*If you see something like PC unable to recognise device, go into device and Update Driver and choose "Automatic....."
Disconnect and Reconnect with MTP and USB Debugging
Wait for PC to recognise device and install driver
Restart N7 in bootloader
Wait for PC to recognise device and install driver
Profit
* My PC OS is Win 8.1 Pro 64bit
make sure mtp is switched off, i couldnt get adb or fastboot on my nexus just now . switched off mtp and works fine
Has anyone gotten this to work? When I type ADB devices, I get:
Code:
????????? no permissions
I rebooted into fastboot with no luck either. Except now ADB doesn't even pick up any devices. And yes, I enabled USB debug mode and unauthorized sources.
Thanks!

I'd guess you are using an older version of the toolkit. Try downloading the latest SDK and using it to see if that helps (it'll also update to the latest drivers). Good luck.

Linux - Ubuntu to be more specific.
So I figured out the issue. I rebooted into the bootloader (unplug NP, plug it back in, immediately hold the button located on the bottom of the player until the light flashes), typed fastboot devices and it finally recognized the device. ADB still however did not recognize the device while in the bootloader until I powered it back on. Very strange... Not sure if the order I did things made a difference but I'm able to connect to the interface now.
Hope this helps someone. Cheers!

I had the same issue on Ubuntu. You need to run ADB with sudo...why? I have no idea...but I found a post suggesting it on StackOverflow and it worked...so I'm not questioning it.
Before doing anything below, have you installed adb via apt-get? If so, remove it and just put a link to your SDK manager adb and fastboot in a folder included in your PATH or add the directory to the path, then start a new shell before proceeding. The adb and fastboot provided by apt-get are old.
Do the following:
Have your device plugged in and fully booted and with USB debugging enabled
run this command: "sudo adb kill-server && adb start-server"
You should be prompted on the device to authorize the access of your computer via adb
run "adb devices" to make sure that it all worked correctly
Been trying to get an adb connection to this phone. I'm on the latest Sprint available OTA (NMJ32F). Have not side loaded the later version. Never rooted.
When connecting the phone to PC, device manager shows "Essential Phone ADB" is working properly. I also tried the Google generic ADB driver. The phone also shows a notification "ADB debugging is connected. Tap to disable".
"adb devices” always returns empty. I am able to adb other devices.
I think the problem is the phone is not asking me to authorize the ADB connection as my other phones and tablets normally do.
Any idea?
Did you get permissions on your phone when popup appears?
No. The phone doesn't pop up the permission question. But I don't know why.
Don't know but as long as you don't give permission you can't sideload

Try the usb driver and SDK platform tools directly from Essential website:
https://www.essential.com/developer/current-builds
I am using the drivers from Essential website. However, I was using the lastest Unified Android Toolkit for the adb command. Looks like it may be outdated, as the adb.exe and it's dll's in the link from Essential website is newer. I will try the platform tools from there and see if there is a difference.
Thanks!
Is USB debugging enabled in Developer settings?
Are you in Fastboot? Did you try "fastboot devices"?
ADB devices returns your device is offline?
