You don't need to change the armboot.bin. It's just kernel.bin and di.bin that need updating on both sd:/sneek and usb:/sneek folders.
It's probably best to rename or delete nandcfg.bin and diconfig.bin. Use modmii to create the kernel.bin and di.bin from the elf files.
There is more involved than renaming the elf files.
