Root adb shell error: more than one device and emulator

Tried to search but couldn't find anything on this.

I'm trying to use 'adb shell' to begin blocking OTA updates, and encountered this error message.

thoughts anyone?
 
I killed the server, as instructed, then made sure the install command was directed, via the -s <serial number>, the install xxx.apx to the correct device. Device name/serial number (seems to be the same thing) can be found via the adb devices command
 
If you are banging your head because something is preventing that root or hack from working and this error pops up, maybe this can help.

I had a program called, "BlueStacks" running on my PC which is in fact an emulator that allows me to run Android Apps on my PC. However, when you are working with roots, it is a horrible program to have running in the background.

Quick Fix: Exit out of Bluestacks and start the root again. It will run smoothly now.

Also: If you have any other programs like BlueStacks that allow you to run droid apps on your pc, good idea to shut them down too.

Hope this cures for you, what was a BIG problem for me.

Thanks, that worked.;)

This simply means that one emulator is already running (could be minimized in another command window, or in the background).

How to resolve:

1) Run adb devices
should reveal something like:

List of devices attached
10.0.0.10:5555 device
10.0.0.12:5555 device

Then simply unmount the one you don't care about, leaving the one you do:

2) Run adb disconnect 10.0.0.10

Just tried it, works every time.
