Why upgrade failed?
 

Dears, is there some one can help me resume my nokia 770 ?
A bad experience: when I update my 770 to Hack os 2007 ! it's work well, but when I flash back to SU-18_2006SE_3.2006.49-2_PR_F5_MR0_ARM.bin, my 770 can not work , screen has no icon, so I flashed to Hack os 2007 again, still no screen show here !
too bad, I'am not at US, so can not enjoy servicing .

I would go with re-download the OS from Nokia, or maybe download twice of the same file to compare the file length. I was burned once with a bad download. I suspect you have a bad download and caused the flash failure. Post back your findings. That will help others.
