. I just have a 4.5-4u with Gateway 2.0b2 .
about a month or so.
I briked my Emunand TWICE and lost a kingston SD card.
No Blue screen but all app except settings and eshop are missing.
upper screen shows nothing but wallpaper(I mean background) even no battery icon
all apps and carts are not functional .
Here is what I did
=========================
I have a 4.5-4U 3DS with kindston 4G SD [ brought 2nd hand and it's wired no video function in camera ]
Gateway with 2.0beta1.
backed up NAND and upgraded Emunand to 6.3-10U
Just play all sort of 3DS games (JP US EU and even TW)
play Nds games with R4 [gateway exp is installed with this R4]
go to eshop and download demos and play. [3 demos including 'Phoenix Wright - Ace Attorney - Dual Destinies']
Every thing went fine .
But one day I entered 4.5's Data mangement ;
and went out.
my demos were all gone [4.5 deleted them]
so I just went to emunand 6.3 's eshop redownload them.
I clicked download later for 6-8 demos .
Then I mistaken clicked download now when downloading “Phoenix Wright - Ace Attorney - Dual Destinies” (I played this for onece)
so It went on...
and an error showed up says something went wrong .told I should restart eshop.
I clicked ok.
Then black screen showup ask me to reboot.
Just reboot and successfully entered 4.5.
I went to 6.3 and then app except settings and eshop are missing.
upper screen shows nothing but wallpaper(I mean background) even no battery icon.
all apps and carts are not functional .

I used to backup SD and emunand everyday .
So I used dd to resore my 6.3.
then everything went fine again. so I decided to test that bug.
I repeated my steps.
again I got briked .
then restore It with dd.
But when I insert to 3DS 4.5
error show up says SD can't be recognized.
tried dd and many other tools .But sadly my SD died.
I brought a new sandisk 8G and reinstall emunand upgrade to gateway2.0b2 and 7.1.
everything went fine now
=========================================
So , under emuNand can accessing OFW's NAND data
And anything writing write NAND maybe dangerous.
such as eshop , settings.
anything writing write SD with encrypt data maybe risky.
such as eshop, streetpass spotpass some game's SD eatra data.
=====================================
Also when I briked my emunand . I DID NOT REBOOT IMMEDIATELY. !!!!!!!!!!!
