Hi,
Sorry for the slow reply. Gmail failed to notify me about group messages.
In any case, device "offline" typically occurs for two reasons:
- When plugging your phone into your computer, you should see an authorization pop-up on your phone. It's necessary to authorize your computer; otherwise, your phone will show up as offline. You should be able to force this again by going into phone settings > Developer options > Revoke USB debugging authorizations. Note that Developer options is a hidden settings menu that can be enabled by going to phone Settings > About phone > tap on build number 7 times.
- A flaky USB cable can also cause offline status.
Also, check to see if another version of adb was inadvertently installed on your computer. If so, do make sure that it's picking up your device ("adb devices" from the terminal). If you're not sure, you can also type "adb kill-server" to terminate any adb processes. Klink should then pick up the one that it's bundled with.
Does that help?
