Hey guys

I am flashing an Hitachi GDR3120   ROM 59 from a 360 elite.  This is 2nd hand elite that was previously flashed but the owner does not know what firmware.
So i used Jungle flasher 0.1.62 to flash IExtreme 1.51 this seems so work ok. I now get an E66 error on the 360. I know this is due to wrong firmware.

What can i do to fix this. ?? any ideas.
