[HTC One SV] Modding.MyMind:
supersu is fixed. Can flash and gain root. I permanently unrooted my device for the official test and success. The initial problem I had was in the script... A stupid (") mark.... Spent hours looking for the problem and it came down to one " mark... But, I found it and its up and going. :) even tested it on my girlfriends HTC Evo Design 4g as she too needed root now for certain things - success.

My apologies for the past problems and delays.

Here is the code used for the su and busybox flash zip. The quotation in red is what was initially missing and overlooked for hours before I found it.
