Make sure USB debug is enabled. Make sure the phone is not on the lock screen while plugged in. Unplug and replug the device. Restart the adb service (adb kill-server, then adb start-server).

These are the easiest things to try that come to mind.

Debugging is on ,lockscreen is not on . unplugged my phone and killed and restarted the server and still showing offline. Just used the same computer to unlock a HTC droid incredible 2 today and restore a lg optimus elite from a bootloop cycle. So I am pretty sure its not a issue with the computer I am using ,but I guess its time to try another computer and see if it changes anything. Any ideas or help is much appreciated and thanks nimdae for the input

You should be able to update the tools through the manager, though I've been having trouble using the latest manager myself (it doesn't load). Otherwise, you can go to dev.android.com and download the latest package which includes the tools.

Got the new version install . and I plan to flash back to 4.4 version 19.5.3 for my phone. RSD lite is still not detecting the phone when it switches to fastboot so that brought up the question in my mind do I need to update fastboot or was this done when I updated the adb and is there anything else I might be forgetting to do b4 I start this since I will be using the manual method to flash this in fastboot? Any and all feedback is greatly appreciated. This is my everyday driver and I'm still paying for it thru the edge plan.

usb debugging is not necessary for fastboot commands, only ADB; however, it sounds to me like you do not have the proper drivers installed for the device if RSD is not detecting it. I would delete all Motorola drivers and Motorola Device manager, reboot computer with device unplugged, reinstall Device Manager, and then connect device. You can also download Minimal ADB and Fastboot (Google search) and it is a lot less hassle than trying to use the SDK.

You may also try using a different USB cable on a different USB port (not USB 3.0). Sometimes that causes problems.

In the end my problem was my SDK was not updated ,so the device was only seen as offline as for why rsd doesn't detect it in fastboot I do not know ,but I was able to manually flash it in the end. Now I'm loving w/p off and root with safe strap installed despite the locked bl

    Yes, if it reports offline, then you don't have ADB 1.0.31. Type "adb version" and make sure it's 1.0.31.
