Ok so here is something I was working on recently - 'UpdateCDN'
It downloads the titles ('programs') that make up a 3DS FW update and create .cias to use with devmenu (import all - L+R+A is useful here!)
It uses the CSV files on http://yls8.mtheall.com/ninupdates/reports.php - without the work this guy did to get this data in the first place this would not exist!
From my 4.5 JPN emunand, I manually updated to 6.3, and then manually downgraded (via an ugly trick/hack)...
[Release] UpdateCDN - download 3DS FW contents, create installable .cia
