Thought I'd post this since it took me ages to figure this out. Some of you like me who may wanna dual coldboot into either Gateway or Reinand/Rxtools. Know that installing MicroSD Manager CIA will break the Reinand/RXTools. For the longest time I couldn't figure out why my N3DSXL could dualboot GW and Reinand while my N3DS would always crash on Reinand and Rxtools, yet can boot into GW without issues. Turns out that MicroSD Manager App that can only be installed on GW Emunand is the culprit. So that's that mystery solved. If any of you happen to want to setup a dual coldboot console, don't install the MicroSD Manager CIA, it's very handy, but will crash your Rei and RX, though it seems to work fine on GW. If someone figures out a workaround let me know. The app is very very handy as it allow you to enter MicroSD Manager without being booted back to sysnand. But as with all things good, there's the bad side.
