After I updated to System Menu 4.2 (with Waninkoko's Firmware Updater) I reinstalled Preloader rev 4 and I got this error message in Preloader: "Preloader error autobooting system menu. ES_DiVerify failed!" I searched around and there was someone who had selected another System Menu IOS, to IOS60 instead of IOS70 with success. I tried this, but the System Menu IOS that is displayed now is IOS560 (under Settings) and I can not select another IOS, start System Menu, HBC or BootMii IOS. Load / Install File results in : "Writing file failed!" Preloader displays IOSv60 System Menu v0 Is there a way out of this? EDIT: When I insert a SD with the BootMii folder and try to launch BootMii IOS from Preloader I get this happy message: "Error booting BootMii, maybe IOS not installed?"
