YES, you did.. Two options spring to mind
First: (Low probability) if you have a 3-valve bypass did you CLOSE the bypass valve? you clearly opened the other two but did you CLOSE the bypass valve.. And again I suspect you did.
Second:(High probability) Do you have an exterior shower.
#1 Cause of "NO HOT WATER" is the outside shower
Mixing valves open.. Shower heat cut off closed.
Solution: Close mixing valves
