Firmware Upgrade via TFTP Fails

[drogstar]

Im trying to update my SA/Webstar epc2100r2 (BCM3349) firmware to the haxorware via the http://192.168.100.1/__swdld.asp update page.

Whenever my tftp tries to send the file the modem ends the connection.

Modem Log:

SW upgrade Failed after download - Incompatible SW file

TFTP Log:

Connection received from 192.168.100.1 on port 1037 [30/11 14:28:20.578]
Read request for file <1.bin>. Mode octet [30/11 14:28:20.593]
Using local port 4189 [30/11 14:28:20.593]
File <1.bin> : error 10054 in system call recv An existing connection was forcibly closed by the remote host. [30/11 14:28:22.859]

Any ideas how to fix this?

Many Thanks.

...
that only works for signed firmwares...
and in many cases doesnt work at all...

ahh ok, i guessed it would be some sort of validation on the binary. I guess ill try serial it if not the dreaded jtag method >.>
