for your problem installing preloader v.29
first of all: did you use trucha bug restorer to downgrade ios15, use the ios15 to reconfigure ios36 and then restore ios15?
after this... did you installed ios60 patched?
and... do you know there is a new version of preloader? it has a new name... Priiloader.
you can find it on "wiibrew"
good night and good luck!
p.s.: I should be able to get an original disc of ssbb an lego indiana jones at the end of this month!
still keeping my finger crossed!
