Can someone confirm this statement?
There is currently no way to update the emummc firmware on an ipatched switch because inorder to do so without burning fuses and messing up the original firmware/sysnand you have to enable autorcm. autorcm well brick your ipatched switch.
So if I'm currently running emummc CFW 4.1.0 on an ipatched switch I'm currently stuck on this firmware.
First, you didn't need to receive a dead/dying thread.
Second, your statement is untrue. You can update your emuNAND to any system version. You just need to make sure you're on your emuNAND when you perform the system update, because you don't want to accidentally update your sysNAND.
If it's a clean emuNAND, you can update your emuNAND in the system settings. If it's an offline dirty emuNAND (i.e. You use it for hacks), you should update your emuNAND using ChoiDujourNX.
Updating an emuNAND will not burn fuses, and it will not install AutoRCM.
