As I was struggling with this I though I would share the info to help people get NAND Android installed.
Firstly if you are getting the below message you are most likely missing a couple of file's in the same directory called EnterBootloader and rapitool (which I have included in this post)
"Error Description: USB init failed
Info: .\RSPL\RSPL.cpp (723)"
Simply place those file in the same Directory as the DAF.exe file and vola it should now start the flashing from the DAF.exe file.
I hope this helps.
If you are running XP Go to control panel and then active sync while connected in MAGLDR while it states Wait USB...USB and un-check Allow USB then right click the DAF.exe and run as Admin, that should allow you to install.
