Hola, I downgraded an O3DS XL to 9.2 and I haven't split nand/installed CFW yet. That's because I want to hang on to my mii plaza progress - streetpasses, puzzles, etc. I did this on my other console: after the downgrade, I dumped my sysNAND to .bin, backed up my entire SD card drag+drop style using TeraCopy, then unlinked and copied SD back. When I connected my NNID on emuNAND I got 1 mii back but the best I could do was get like the first 5 puzzles back, and all other puzzles are no longer unlocked (so i lost like 800 pieces). Also no people in my plaza anymore, etc. So I been trying to figure out how to restore that old data, using extdata_dump, digging through folders, etc. but I just can't figure it out. It's sort of an acceptable loss, since this console is a beater and I was doing this through pretty much as a test run to see how it would work on my main console, but I still would love to get that progress back. In the meantime, on my other console (my main one), I have downgraded but not unlinked, as I am not at all willing to risk losing all my plaza data this time. So even if I can't find a way to get my old data back (reasonable), I'd love to find a way to get a CFW on my real console without losing that data this time around. I have searched *a lot*, but mostly I just find people saying the same thing - lost puzzle data, etc. Most people dont' seem to really care about it so they don't mind formatting cuz you can still get savegames and all that back. This time I've gone so far as to make .iso backups in addition to drag and drop, plus I have 2 SD cards with the same data just in case... Anyways, if there's a guide or tool somewhere I'm totally missing, let me know!
