It seems you've been looking for this for awhile. I think your answer might be here: [Only registered and activated users can see links. ]. If Aekhong can't (or won't) tell you how to do it, then best give up. You could try using your original boot.bin combined with SG fw and flash back to full original us fw if it doesn't work. If you're not sure what to do, don't do it.
