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

Now I know your first thought “I bet this tool didn’t even use Search like the rest of the shlubs on here”. Well you are mistaken. I have not only searched xda but even tried Google and Yahoo (just in case) as well. I have found numerous posts (like HERE and HERE and many others) with similar situations but haven’t seen a resolution. Here is the rundown:
Running JF’s 1.5 CRB21 ROM
Hard SPL (HSPL10.95.3000)
JF’s 1.43 Recovery Image
SDK 1.5_r1
Fastboot.exe placed in System32
Haykuro’s Updated Drivers placed in System32
Windows XP 2002 SP3
I have been able to flash nandroid backups without issue in the past but adb started intermittently not recognizing my phone when I flashed from JF’s RC33 to JF’s 1.5. I was able to restore a backup once but now adb will not recognize my phone at ALL. Tried different USB plugs and cables with no result. If I mount the phone to view the SD card via Windows Explorer it shows as “HTC Dream Composite ADB Interface” in Device Manager. However if I boot into the Bootloader (which I have the Hard SPL HSPL10.95.3000) , connect via USB, hit back to go into Fastboot, and try to flash a nandroid backup I get "Waiting on Device" infinitely. “Adb shell” yields “Device Not Found”. The "adb devices" command yields a blank list. But if I type "Fastboot Reboot" it will reboot the phone so I know it is communicating and the cable is in good order. I have deleted my SDK and drivers and re-downloaded/installed them and STILL cannot get adb to connect. It has to be something simple I am missing here right? Any idea why this would have worked without issue in the past and now not at all? Could it have been a Windows Security update? (That's about the only thing I can thing that has changed other than the newer ROM)
Thank you for your help.
Did you update you USB Drivers or try reloading them?
Also.... Settings > Applications > Development > USB debugging has to be checked....
and stop being a tool.
nah im jk.
USB Debugging is checked - thanks Senorkabob for at least trying to help.
Phoenix - I apologize for posting in the wrong place. If I could move it, I would. I apparently missed the "How to be a Good Xda Citizen" thread... I shall repent
Could you choose View -> "Devices by Connections" in Device Manager and uninstall the USB Root Hub device your android is connected to. This should clean up all the device nodes and allow you a clean start. Click "Scan for hardware changes" in the toolbar and wait for the system to detect your phone. In the new hardware detected wizard, make sure you specify the path to drivers folder of the correct architecture, i.e. x86 or x64.

Thanks man - I was able to install the drivers but am still unable to view my device. It shows as "HTC Dream" in Device Manager but when I run "adb devices" in the command line, it yields a blank list. Further commands (I.e. adb shell) say "cannot find device. Running fastboot commands result in "waiting on device". This happens on both my laptop and my home pc so I am beginning to think it's the phone. Should I have something loaded on the phone? I have USB Debugging checked so that's not it. Any ideas?
possibly the problem is that ADB does not work in Bootloader mode, it is designed to work while the phone is running.
However if I boot into the Bootloader (which I have the Hard SPL HSPL10.95.3000) , connect via USB, hit back to go into Fastboot, and try to flash a nandroid backup I get "Waiting on Device" infinitely. “Adb shell” yields “Device Not Found”.

Yuo are obviously trying this in bootloader mode, underline for emphasis.
try >fastboot devices

Otherwise try ADB while in the OS already.
Hello all,
I'm having difficulty trying to run EFS Pro v2.0.70/v2.0.72 to backup my EFS folder on my GT-I9505. I get stuck at the part when it says "Initializing ADB server..." and it just sits there. I just want to point out that I had made a backup of my EFS folder on my GT-I9505 when I first got my phone (around May), but it seems to have been deleted! Anyway, I found some good steps in another thread, as follows:
Before starting, check the following:
Device is fully rooted
SuperSU (or equivalent) is active
USB debugging is ON (Settings->More->About device: Tap several times on "Build number" to enable Developer options and tick USB debugging)
Busybox downloaded AND installed (normal or smart) on your device
Microsoft .NET Framework 4.0 installed on your PC
Samsung USB driver is installed (either by installing Kies or just the driver alone.
Kies is not active (neither as application nor process, check Windows Taskmanager)
ADB fully functional ("adb devices" recognises your phone) -- (look here for a basic ADB tutorial/how to)
In case ADB is not running you need to install the ADB driver
Run EFS Professional as administrator.
Make sure to grant SuperSU access to Shell and confirm the RSA fingerprint request once they pop up on your screen.
Of course, your device should be on the home screen, not on the lock screen
I've followed all these steps, checking each methodically, and guess what, I'm still stuck at "initializing ADB server..."! I even go to cmd and type in "adb devices" and my phone shows up, I see on my phone that a shell has been granted, and yes, I am rooted, I have busybox, and Samsung drivers, .NET 4.0 framework and USB debugging, it's driving me mad, I've even tried different USB ports, and nothing!
If anyone has any suggestions, please fire away!
I have the exact same problem, but with my S3 (I9300) ...
No one who can help?
Did you get sorted my i9505 is the same and I have two phones but one wont work..
Hi.
I have a nexus 7 2012 edition which turns on with The Google written logo and under the screen with a padlock. After that it will be in bootloop with a black screen ( I can see the backlight turning on/off). This is also if pressing the power+volume down combination. Seems bootloader is corrupted. Anyway I installed everything on pc plus I'm using the WugFresh Nexus Root Toolkit and here are some examples which show what errors I'm encountering when trying to flash stock firmware .
Log:
Checking ADB/FASTBOOT Connectivity
adb devices
015d4a5ed8500c01 unauthorized
fastboot devices
There is also a notification popup which tells me:
"An ADB Interface device was found but it was listed as "unauthorized"
-Accept the RSA security prompt and check "Always allow from this computer"
At this point I don't know what to do, can you help me?

Hi, Sunil_511...
Bit speculative this, and I can't say for certain if the following solution would work, because I've never had this problem myself. It also requires that your Nexus 7 be in a fully bootable state.
Go to your Nexus 7 Developer Options in the devices settings and tap on 'Revoke USB debugging authorisations'. Tap on OK to confirm. See attached screenshot.
This, theoretically, should wipe the slate clean.
Reboot both your N7 and your PC/laptop and when you next reconnect your N7 to your PC/laptop, you'll be asked to authorise this new USB connection when you perform some action that requires it.
Well, that's the plan anyway.
Good luck?.
Rgrds,
Ged.
Nope, in my case my tab is not booting to recovery or system. The only option is adb and it is showing unauthorized. My last option what i think off is to change the motherboard.

Google search is your friend. I found the following two methods which seems to have worked for some people.
1. If you are using OS X*:
Reboot your phone into recovery mode.
Connect it to your computer.
Open the terminal and type:
cd ~/.android
adb push adbkey.pub /data/misc/adb/adb_keys
All done! Just adb shell reboot and feel the power!
*For Windows 10, .android directory is located in your the base of your C:\User\user_name directory.
2. Go to where you have stored adb files, open that folder and press "CTRL+SHIFT+Right Click" and select and click on Open Command Prompt option
Now enter following command
adb start-server (Enter)
adb usb (Enter)
After that your device is no longer unauthorized and you should be able to use any command in your Android Mobile using PC/ Computer.
If these fixes don't work, SEARCH.
thanks buddy, i have tried pushing the adb keys but no luck. I will try tge second option. Will let you know after trying.
No difference still the same

Hi there,
I've got a problem; my device is not seen properly by latest Minimal ADB (unauthorized), I've tried many solutions such: reconnecting, re-enabling usb debbuging, restarting adb servers, deleting adbkey file from /.android. Is there something else I can do? Thanks in advance,

You are using linux? If yes, try sudo.....
If not, do not restart device in fastboot and plug it in pc. Plug it when booted in system and type adb reboot bootloader. Be sure to have adb turned on in developer options.
After doing what u said; I've got:
This adb server's $ADB_VENDOR_KEYS is not set
Try 'adb kill server' if that seems wrong.
Otherwise check for a confirmation dialog on your device."
I've already done kill/start multiple times. What's more, I have no RSA popup whatsoever.

Go to developers options and click on revoke usb debugging authorizations and conform the prompt.
No reconnect the device to PC and check for RSA prompt in phone and accept it.
I haven't got revoke option, I believe it is due to custom kernel I installed, so the question is if I install custom ROM, the kernel is going to be reinstalled with ROMs one, what should I do tho?

This should fix it.
1. Go to the /.android folder and take copy of "adbkey.pub" file.
2. Rename copy as "adbkeys" Without any file extension.
3. Move "adbkeys" into your phone /data/misc/adb
4. Not sure if necessary but set permissions to 640 (-rw-r-----)
5. You might need to restart adb server "adb kill-server"
Now when you try it should work as expected.
It didn't work.
Reinstall phone driver. It may work
Did it and nothing.

What are you wanting to do with ADB?
What is your end goal?
Is there another way of doing it?
Another stupid question have you tried a different cable as I have had the same issue it was the cable
I want to try custom roms, and flash new TWRP, and what if I flash new rom then I'll want to go back, but can't coz I cannot connect to adb.
I was able to make it work; I restored backup.
I mean, fastboot is the one you need in order to flash twrp. Does it not recognise your phone if you plug it in while in fastboot mode?
The popup to allow USB debugging from my computer doesn't popup when I connect my Oneplus 5 to my computer, and thus ADB devices comes back empty. This is only happening for my PC on stock Rom. When I tried installing another Rom, the popup to allow USB debug option comes and the phone is getting detected in my PC. Even on stock Rom, in another PC popup to allow usb debug option comes, only in my PC stock Rom it is not getting detected. Not sure whats and wheres the issue(PC or Phone)?!
I I've rooted my phone before and it was working fine previously and it stopped being detect after OB10 . I looked online too and tried options like restarting, turning debugging off and on, revoke USB authorization etc...... nothing works Please HELP!!!!

If you have a folder named '.android' in your User Directory, delete it and then try again. If this doesn't work uninstall your current ADB software and reinstall the Platform Tools package:
https://developer.android.com/studio/releases/platform-tools
I've had this once or twice and that always did the job.

I've had this once or twice and that always did the job.

On the Stock ROM, where you are having the trouble, does your PC see the phone when you connect it. i.e does it show up as a device in Explorer and Device Manager? When you enable MTP can you transfer files?
As it's only a problem on the OOS ROM, i wonder if it's a Driver issue. When you installed the Platform Tools, did you install the Google USB Drivers?
Also have a look here. There may be some useful information:

i had a same problem like you
had the same problem on my phone (manually added the adb public key to get access), only got fixed by factory reset. the popup just didnt show no matter what, even though adb worked.
