Thank you for the guide - it has been very helpful. I have gotten to the point of "remove ios249 with wad manger".
3 scenarios of what is happening:
1. load bootmii from home button. Says "IOS successfully installed, sdio startup () rv=o, fat_driver: disk init failed, please insert sd card, failed to load boot.dol from front sd card reader. The last 4 lines repeatedy scroll until restart console.
2. launch WAD manager 1.4 from HBC or from SD card. Says select source device , press A. Select A and it returns [+] mounting device, please wait ... ERROR! (ret=-1), press any button to continue. You can continue to press A with the same results or exit back to the HBC.
3. launch WAD manager 1.5 from HBC. Says select IOS version to use . Can scroll through a list of IOS numbers but it initially comes uo at IOS249. When I click A (default is IOS249), the WAD manager screen stays up but locks up. Can no longer scroll nor do anything until hard reboot the console.
Any suggestions are very appreciated.
