Yes I have. Sometimes it will boot without needing the usb but other times it will load with just a black screen and the harddrive is doing something but no video. Other times it boot loops and I have to reinstall. Here is how I am installing: Run myhack usb installer, use custom extra folder (d830 bootpack), say yes to removed problem kexts, reboot. Run EDP, reboot. I have to manually install a boot loader because it can't find one upon reboot so I have been using the newest chameleon pkg from here.
