As above.
You'll need ADB active on the phone.
And a new / updated version of the ADB drivers / tools on your desktop.
Also, you will get a dialog prompt on the phone to confirm a security encrypted key (to allow ADB between your desktop and your phone)
This is something Google introduced on 4.1 (I think) which, if is not set, will end in a "devices not found" when trying to use ADB

Revoke all USB authorisation.
Try reconnecting.
And authorize when prompted!
If it doesnt work!
Also Please post Does your device show up in device manager? IF yes by what name? Is there an ADB Interface?

Hello. As the title says I get that error. I need to run adb shell to use some commands. When I type "adb devices" I don't get any device listed (the long name).
My OS is Windows 8.1 64bit.
Thanks.

Nexus 5. In SDK Manager it says that Google USB Drivers are installed. I don't get it. When I use the phone to flash images in fastboot it works perfectly but ADB doesn't work.

Try to disable/enable USB debugging again and check if the adb device is listed in your device manager.
You can also try this ADB/fastboot bundle (Includes the google drivers) and work on all folders

adb shell
error: device unauthorized. Please check the confirmation dialog on your device.
adb devices
List of devices attached
0466e0f6215cb6cc unauthorized
i tried may tips online but it still not work.
adb confirmation dialog not appearing on nexus 5
adb working on twrp but not showing confirmation dialog on android 6.0 nexus 5
Try revoking all authorizations on the phone and then try adb commands to see if the dialog box appears.
Can't revoke there are no voice for revoking. Anyway I did also deleted the /data/adb/adb_keys but at the end this dialog box won't appear
Debugging is enabled?
Yes it is
Did you try a different computer or operating system?
Maybe this will help: http://forum.xda-developers.com/verizon-lg-g3/help/unable-to-access-adb-t2830087
I am also getting same error but ..
only on one specific rom.
Other roms are working fine.
Tried on win8.1 , win10, ubuntu, mint.
I only use win7 so I can't comment about other operating systems.

It's strange that you didn't have the option to revoke ADB authorization before the update.

Hi Guys, I just want to ask if there will be a possible solution on how I will be able to use my phone again. I accidentally deleted the OS and the backup of my OS. When I tried to connect my phone to a pc, the pc wont read my phone. Any possible solution on how will I connect it or any solutions for my problem. I also dont have the custom rom zip on my sdcard anymore.

Ahh..
Just boot into Twrp,connect your device to Pc and transfer any ROM and flash it.Gee,twrp supports mtp,which means you can transfer stuff.Alternatively,if mtp is not working for any reason,you can use usb otg as well.

I forgot to mention you can use adb sideload as well.
Since you've adb drivers installed,boot into twrp,go to advanced and enable adb sideload,connect to PC.Copy the ROM zip in your adb folder(where adb files are situated),press shift and simultaneously hit right button on your mouse,select open cmd here.Now write command "adb devices"(obviously without quotes), if all goes well,you'll see your device Id there,proceed and write command "adb sideload ROM name.zip" (where ROM name= exact name of file you're trying to flash).The flashing progress should start now.

Hello Everyone,
I would like to learn how to remove bloatware Apps from my Android phone.
I have tried using "ADB commands" but for some reason my computer doesn't recognize/find my Android phone when I connect it to it.
Please help.
Thanks in advance
Download drivers for samsung and enabled adb developer option then type following "adb devices" press enter and should see serial number indicating phone connected via adb

Hello, and Thanks
I have done that exactly, but it still doesn't work.
And I can't figure out why is not working.
I have installed the Samsung driver, allowed the ADB function on my phone from "Developer Options" etc.
In addition to the advices by petiolarissean , check whether the driver works well, please.
In the 'Devices Manager' of your Windows, check the driver for your Android phone.
If this doesn't work yet, change an usb cable and then try again.
Only to have mentioned it:
So-called bloatware typically is housed in Android's locations /system and/or /system/priv--apps what only can get accessed by Android's root-user after successfully mounted as RW.

If a USB port is disabled on a device and I'm unable to adb into it, is there any file or method I can try to enable USB port? When I ADbB devices it reads unauthorized. If I try and ADB mount I get the ADB help screen.. please help

How did you find out that the USB port is disabled? With the command 'adb devices' what is the output? Do you get an alphanumeric output along with "unauthorised"? If so, it doesn't mean that the USB port is disabled. It means that the prompt on your device (when you use the command) asking whether to allow the adb connection has not been approved.
If you don't get the prompt, then search for a solution for that.

Is adb the only way to do phone to phone using terminal prompts? Is there a back door into the target device if ADB don't work?

ADB for phone to phone? I don't understand the question. ADB will work if it is authorised on your device.
