Android ADB device offline, can't issue commands -

i can't connect device anymore using adb through command line or in eclipse.

running command

adb devices

returns device name, says it's offline.

things i've tried.

toggled android debugging mode reinstalled google usb driver restored os working backup (cyanogenmod) swapped usb cord rebooted phone/computer multiple times updated android sdk

i don't have clue what's going on. else think can try, i'm ears.

to clear, if you're having same issue problem out-of-date sdk. of 4.2.2 there security feature requires confirm rsa fingerprint of connecting device. open sdk manager , update tools! reboot.

i got same problem today after nexus 7 , galaxy nexus updated android 4.2.2.

the thing fixed me upgrade sdk platform-tools r16.0.1. me, version not displayed in sdk manager, pulled downwards http://dl.google.com/android/repository/platform-tools_r16.0.1-windows.zip directly.

you need rename platform-tools directory , unzip android-sdk-windows/platform-tools. using sdk manager, had updated latest sdk-tools before this.

if whole eclipse , adt ancient, may need update them well, didn't need to.

note: may need run sdk manager twice (once update itself) before see latest packages.
