HI, I uninstalled Rockbox, and cleaned all folders and all files, keeping just the Apple's OS in iPod. I'm pretty shure that I didn't forget to delete anyone of Rockbox files.
Then, I installed Rockbox again, and it not comes in default settings. It opened in icatcher and the hardware EQ settings like the way I did before uninstall.
Where's this settings are memorized ?
PS: I repeat this operation by 3 times and it always happened.
