stompers, thanks for the script it worked for a sb5101 that was broken, still having the same problem with the sb5100. Usbjtag software detects the modem, erases the flash and al but it doesn't write the flash. Im going to keep trying.

Thanks!

Funny, the sb5100 is the only box I used it on the timing thing is very important.

If you use NT I can help you debrick it.Basically you need to sprogram it. But there are two programs built in NT for sprogram. One is using DMA and one is not. There are slightly different and sometime one worked and sometime the other worked.

I have the old usbjtag and I use

detect
ldram boot
ldram image0
program boot
program image0

usually with this cable I use

ldram 9fc00000
program 9fc00000 200000

when I load the full backup (2mb), but as I said, I have the usbjtag cable not the usbjtag NT

I tried both methods, but they didn't worked.
