Don't be fooled by the htcdev site boot unlock. You still remain s-on, and the boot is still locked. Kernel needs to be flashed separately, cant flash radios... Worse, htc has avery poor track record in providing firmware source codes for its phone h/w components (twin 3D cam in evo3D, cam f/w for almost all phones, no third party support), ergo, no official cyanogen mod 10,11 or wany such official roms. What you get is some unofficial hack using ersatz codes by a dev experimenting...never stable....no hope outside stock rom....its time to abandon ship than stay on a burning platform (to quote steven Elop).
