Remove update prompt on SysNAND

Hey guys,

I imagine this has been discussed before but I wasn't able to find an answer via forum search.

I'm happily chugging along on my N3DS XL with SysNAND at 9.2 and EmuNAND at 9.5 and RxTools.
Unfortunately in the very brief period I had WiFi enabled when doing this whole process, I managed to find myself with the update prompt on SysNAND. Is there any way to get rid of it? I managed to avoid getting it on EmuNAND...

Thanks in advance.
