22nd of march 2011 i was updated my android SDK tools , after i was updated when i trying to find my device in cmd prompt its showing error: device not found but before my update i was used that adb shell command it was worked good but after update it is not working

i was used these commands
adb kill-server
adb start-server

can any one please helpme:confused:
 
what device?

Try rebooting the phone, and/or a different usb port. If you use eclipse, close it and do the adb kill-server and start-server commands again. If all else fails reboot your pc maybe.

^just some things to try

Do you have a firewall running? You may need to allow eclipse and adb through.

I'm just guessing though I do most of my dev on a phone as I hate the emulator heh :)

Sorry I couldn't be of more help :(
 
When you have your phone connected via USB go to your Device Manager on your Computer and see if your phone is listed there under Portable devices. If not you may have Driver problem.
 
Maybe try downloading a fresh copy of the SDK?

I know there are some serious errors in the SDK updater... What OS do you use? I had my SDK on my D:\\ drive in windows and the updater completely broke when trying to update the tools and platform-tools folders.

Another thing might be to try and create a new Virtual Device <-- try this first
