[q] pleaseee help meee.... Lost my mind topic

Ok i will explain clearly
what i did...
Firstly i tried to follow all videos to root custom my galaxy gear when the first hour when i bought,
i was succesfull. I installed null 23 i root it and then i upload null 23 in my sd card part in my gear with the wondershare mobile go application.
Then i didnt like it and i tried to unroot my gear. And i followed the steps correctly. But..
Activation screen which is connecting with nfc or bluetooth, never let me pass. Even i tried to do nfc, it says try to bluetooth and bluetootg couldnt connect. But they see eachother
and also when i try to root again, odi says success but nothing happening on my screen after i root it.
And now wondershare doesnt work because i am not able to reach usb debug mode settings on my gear. Because i couldnt pass connection screen on gear.
Now i really f....d up
please help me almost 20 times i tried to root and unroot.
I just want my gear as like as first minute of my device.
Please help me asap

thanks...
