I've had ADB working successfully in the past, but now nothing is listed after an "adb devices" command, and a "device not found" error for other commands. I was on Royal Ginger 2, and just updated to the latest CM7 nightly - then wanted to use ADB to tweak a few things and found out something was wrong. What else do I need to do to get adb to recognize my device?
I haven't changed anything on my laptop, which is Win7 64bit, and I've updated everything in SDK Manager. Device Manager on the laptop shows T-Mobile myTouch4g USB Device under Disk drives on the Device Manager, and I believe I have the latest mt4g drivers installed. I'm connecting via USB with debugging turned on, and without turning on USB storage.
Any ideas?
I was finally able to get adb to recognize my device again. FYI, I tried a few different things, but I think what finally got it working was tweaking the *.inf file in the usb_driver folder in SDK, the uninstalling/reinstalling the drivers - as outlined here:

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!

Make sure to use the latest ADB executable, also check if you don't have any other adb.exe in your computer, from command promt: where adb.exe

Hello,
No, adb.exe is up-to-date and there's a single instance of it on my computer.
Problem must be somewhere else.
Thanks anyway

Doesn't work yet..
Tried to delete "C:\Users\Myself\.android" and "Documents\.android".
Did a full search on filesystem, and found no other .android folders.
Thanks anyway.

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

Hi all,
I recently bought a OPT and wanted to root it, but I can't get the RSA Fingerprint dialog to appear.
What I've done:
Installed Android SDK and platform tools and all that stuff according to the guide in the general section
Installed Koush's universal drivers and also specifically installed the Oneplus drivers
Rebooted rebooted rebooted both my computer and phone multiple times
Revoked USB authorization multiple times (according to some this works, but not for me)
Tried both MTP and PTP
Switched off and on developer options and USB Debugging
Factory reset my phone
When I start a command prompt in the platform tools directory and execute "adb version", " Andoid Debug Bridge version 1.0.32 Revision eac51f2bb6a8-android" pops up, so I think my ADB is working properly. But when I execute "ADB devices" the ADB server starts up and then nothing is listed under connected devices.
I'm using Windows 10. Any help would be greatly appreciated. Thanks!
This might work
This didn't work for me, but give it a try.

Trying to run adb results in the USB notification to cycle off/on on the new Moto G5 Plus. I've tried multiple cables, computers, and a factory reset of the phone (both times with the factory image).
Has anyone encountered such an issue?
Basically, I can enable debugging mode and connect my computer, but the moment I issue `adb start-server` the USB notification on the phone begins to cycle. There is no message to authorize the device or anything. For what it's worth, this computer works fine with another device (as does the other). I've deleted the .android directory and saw no change, too.

The `start server` command just begins to run the adb daemon. It is run without explicitly issuing this command if you run something like `adb devices`. It's like setting up the environment without actually querying anything on the device.

I tried this just out of interest... revoked all ADB authorizations, rebooted my phone and PC, and connected and did a "adb start-server". It popped up the authorization windows like normal, I approved it and it worked like normal. Subsequent kill-server and start-server commands had no unusual effects either after revoking authorizations or not.

OK, I tried using a different Android SDK (grabbed from https://dl.google.com/android/repository/platform-tools-latest-linux.zip) and now it's working. There must be something about the one my distribution packaged that is broken.
Code:
$ adb version
Android Debug Bridge version 1.0.39
Revision 8.0.0_r11
$ LD_LIBRARY_PATH=$PWD ./adb version
Android Debug Bridge version 1.0.39
Revision 3db08f2c6889-android
Installed as /home/badhat/Downloads/adb/platform-tools/adb
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?
