P.S. I flashed using this method: Under OSX for me the process is: - Shut down 770. - Plug 770 into computer - Turn on 770 while holding down home key. - "sudo ./flasher -F BETA.SU-18_2006SE_0.2006.22-21_PR_F5_MR0_ARM.bin -f -R" in terminal (Before the last step, you need the flasher.macosx tool, "chmod -x" it to make it executable using the terminal, then, uh, rename it to flasher for convenience) Then you type in your admin password and BAM 2006 OS (Worked in about 2 minutes, props to whoever posted that earlier in the thread)
