hi. so sorry if this was asked before...
i tried to root my note 3 last sunday but no success. i tried two methods;
1 heimdall steps stated here http://wiki.cyanogenmod.org/w/Install_CM_for_hlte but it shows cannot copy in the cmd
2 odin doesn't detect my note 3

any suggestions to solve? i really wanna root my note 3 because my phone is becoming slower even after reset, and i'm not convinced official lollipop will make it much better so not waiting for it. also, don't care about knox/warranty because i bought it on launch date (end sept 2013) so no more warranty.

thanks and sorry again.
