Hi all,
Ok, I tried the ohneschwanzenegger method and that worked perfectly!! :-) I guess it was a corrupted NAND?
Thank you very much to all of you for your help and advice, it took a long while to get this sorted but i'm glad I never gave up. Lesson truly learnt about having brick protection on any modded device and to always backup your NAND!
Now to restore my game saves
Install Bootmii 2
Install HB channel
And BACKUP the NAND!! and keep it in a safe place
Do I really need to install Priloader as well?
