I installed preloader 0.29 a month or so ago. Didn't realise it immediately, but it is now very clear to me the whenever I boot to the system menu the audio is distorted, as though there is a a very metallic sound at the top end. I understand that preloader might have tampered with the system menu when I installed it. Is it possible to revert back to my standard system menu (4.0 Europe)? How would I do this, and how would it affect the fact that I have a working HBC setup? Or do I need to completely remove preloader to fix the issue? Is it safe to use Nandcean to do this (as some folk suggest that using Nandclean and NOT first installing a new system menu could leave me bricked. All advice welcome!
