Don't see it posted elsewhere but looks like SX OS 3.0.4 has been released:
- Support for Switch firmware 10.1.0
SX OS is now fully compatible with the latest Switch Firmware 10.1.0.
- Bug fixed in 'genuine boot' functionality.
Last update we introduced 'genuine boot' for SX Core/Lite users. We were made aware some users had trouble using this while a microSD card was inserted, this has been fixed!
- Minor stability improvements
You know the drill! Under the hood we're always changing things, to increase both stability and performance of your beloved SX OS.
