After flashing back to Mk2 and trying to regain root using safe root. The installer will not see the phone no mater what I do. I've redone drivers, tried multiple computers I've enabled and turned on Debugging. All of that. EVERYTHING else see it. But not ADB it sees my Galaxy s3 no problem.
I first rooted the phone without safe root. But I can't find anything anymore I tried to use terminal emulator but the phone blocks it. Anyone have any Ideas? should I reflash MK2 in odin?

Did you connect as Media device? Then try adb devices.

Yes I did as Media device but what do you mean by adb devices where is that? I did try to find it in a adb shell no luck I tried a totally different computer as well no go.

"adb devices" is a command using the ADB utility. It lists what devices it sees connected.
For example, no phone:

C:\temp\android>adb devices
List of devices attached

Phone attached:
C:\temp\android>adb devices
List of devices attached
32cec1eb device

It's also possible that USB debugging got somehow disabled - settings/more/developer options/usb debugging. Make sure it's selected.

can you also toggle the revoke USB debugging authorization to reset the communication with adb?

Yes, that also can get it re-enabled. Unplug, revoke authorization, unlock the phone, then re-plug it and re-authorize.
In those cases, however, the phone will show up in "adb devices" as "offline".

Thanks I did ADB devices and it showed my device but it said offline, I tried the Revoke Authorization but I can't get the phone to ask if the computer is ok?

Problem solved

I tried the Revoke Authorization but I can't get the phone to ask if the computer is ok prompt. I did a full factory reset and cache wipe four times still only shows offline. I rebooted into recovery saw load update from ADB and adb start-server and got host but couldn't load the install.bat

Problem solved follow this guide

That's one I wouldn't normally think of - if that worked for you, then it means that you had an old, out-of-date version of ADB on your system.
Thanks for letting me know about the fix, as it's a pretty hard one to detect and easily fixed one you know about it.
