Another Question: Fail to synchronize with the host(1)

[sharetop]

I use the mtty.exe backup rom to sd card and restore to device, ok,no problem....

But How can I restore the nbf( download from ftp.xda-developer) file to device...

I try lnb and l command, all report error message:

Fail tosynchronize with the host(1)

Why? what means this error message?

My device is Falcon ( WM2003+CDMA2000) .
"HTC Integrated Re-Flash Utility for bootloader Version:1.19 Falcon DVT version:1.06"

[fireball1331]

i get the message on my hx4700 and i can't work out why. when i use the lnb command with the file that has been modified (.nb0) it says "this application only deal with absolutely image file"... i click ok then it fails to synchronize with host(1)???
When i try the origional (.nbf) same file size... everything fine but the hx4700 does not boot it stays on the HP booting screen, nothing happens. (it says 2.01 at the bottom)
