Lucky enough i had a backup!
it is only partially true: i already changed my fonts many times with rom toolbox on sammy roms. and it worked everytime except for one time when it bricked my rom. The same was it on my old sammy phone. the first time it worked the second time... well I guess you know the answer
(and that taught me the lesson: always have a working backup before doing any changes on a rom)
so I can confirm it can work, but there is a chance that it bricks your phone. so maybe on the second try it works.
