I took the pictures with my iPhone.
I'm going to leave it as is for now and keep testing it until I can get your results. What game were you trying to load with CFG USB Loader when you bricked? I want to trace your steps so if you can think of anything else at all let me know.
I know you changed your HDD format from WBFS to FAT32 so I'm going to run the loaders with WBFS first and then I'll reformat the HDD to FAT32 leaving the configuration files as is. Hopefully I can get to the bottom of the problem.
