So yesterday I used ModMii to ensure all iOSes were up to date and USB Loader GX worked without hiccups.
While everything seemed to work flawlessly (USB Loader GX loaded games pretty quickly over SD!), today I woke up to my Priiloader acting weird. That is, from its menu, it cannot seem to run the Homebrew Channel (complaining about title not installed) or the System Menu (got scared bc it showed a glitched system files corrupted screen; tried again and it booted to a black screen). Fortunately, the Wii can turn on to the System Menu and can open the Homebrew Channel with no apparent sign of malfunctioning.
Unfortunately, I do not have the pictures of the System Menu “brick” screens, but I can provide the SysChecks of my Wii Pre and Post updating the IOSes.
