OK Updated System Menu to 4.1 and many IOS. My Homebrew screen was upside down and system menu has black screen. Can run Priloader to get to Homebrew. Fixed Homebrew upside down screen and reinstalled all IOS and Channels. However still black screened. Any ideas? I think its still a IOS issue but don't know what system menu 4.1U is dependant on. I do have IOS 60 installed. Help the helpless please.
