OH crap!
Not as far as I`m aware. I followed the guide to the T when I did this whole process. It must have been while running SX OS.
No worries tho, at least everyone knows now.
Has anyone confirmed this yet?
Edit: I was able to boot to SX OS after using briccmii V2 just like explained above. I have not tried to restore my 3.0.0 nand backup but I suppose it should work just fine.
1) You can use e-shop to download games and what not. So I`m assuming online works.
2) Yes every reboot you use hekate, the switch will be in RCM mode every reboot or power off.
3) If you boot without hekake you will be in RCM mode (Blank screen)
Hope that helps
