You may have inadvertently "pre-loaded" the cam phasers when you did the belt change
putting a strain on them, resulting in their failure .
did you use ALL the kit
the kit contains a flat bar (to lock cams ,rocker cover off)
2 "wedges" to hold/lock the cam sprockets
a crank locking bracket
that said, parts fail on their own without any "help"
new-fangled VVT sprockets failing IS common
don't beat yourself up about it , unless you're in to that sort of thing
