Calculator [Q] How to completely disable Reverse USB Tethering ?

Hi , I tried this method :

http://forum.xda-developers.com/show....php?t=2287494

to enable reverse tethering, I wasn't successful though even there were no errors, I only tried these codes :

su
netcfg rndis0 dhcp
busybox ifconfig

but since then MyPhoneExplorer and other softwares won't let me connect my phone via USB TILL I enable usb tethering option even though USB Debugging is always on..........

Is there a way I can reset / undo those codes so I could connect to myphoneexplorer easily again ?

Thanks
