Having downgraded IOS15 using Trucha Bug Restorer MOD (I have 4.2E, and regular TBR froze), I was about to launch it again to install a patched IOS36. I realized I had the wrong version of IOS36 (I needed 3351 and I had 3094, again because I used TBR MOD and not regular and because I have 4.2E). I went to get it using NUSD on my PC (Wii isn't connected to the Internet), and the Wii froze on the Homebrew Channel randomly. I want to know if it can be safely powered off and on again (I am a noob and worry too much) with a downgraded IOS15. I have a full backup of the NAND on my PC, and BootMii installed in Boot2 as well, so I hope that if I can't power off/on and try again, I can at least restore the system (if it bricks).
