If you forget to enable debug mode and set USB debugging to enable in settings, there is no way you are able to flash properly.
You should have used Saferoot.zip. As it is the only rooter that installs the root files, so your not flashing a root over your stock ROM.
There should be a sticky about flashing using safe root here, but it seems like nobody is concerned about newbies getting in trouble with flashing.
