It appears that in some instances, seemingly with original firmware lower than 9.2.0, performing a ctrtransfer causes Nintendo DS Settings, in the Settings menu, to fail to load and produce a black screen.
There are also issues in playing DS games on the 3DS.
I believe there is an issue in the ctrtransfer as I have tested a completely OFW firmware on 7.1.0 to be working.
After performing ctrtransfer to version 9.2.0, again OFW, the DS mode settings and DS game ( Pokemon Black/White ) fail to load.
Another person noted issues transferring from version 6.X.X
