So I was able to upgrade to priiloader 0.7 and from there reinstall bootmii as boot2. I then restored my virgin NAND and was good to go. I then used bannerbomb to install HBC and bootmi as both boot2 and IOS and then tried to system update to 4.3. The same thing happened, update fails and the reason it gives is "internet connection error" rebooted and then loads priiloader as bootmii has been removed.
I'm going to NAND restore again but what am I doing wrong?
