Webstar 2100 error writing dynamic...

[mrcrisp]

Hi, I have successfully flashed 2 Ambit modems, and trying to do a Webstar epc2100. The flash goes on using the max232 and i power down the modem, connect via telnet in hyperterminal and the flashed software comes up fine and i enter the modem.

Then if i try to write anything to it, it just tells me:
Error! Unable to write dynamic non-vol settings...

Then I boot the modem down, and the firmware reverts back to the original and im back to having to flash it with the max232 again.

Any idea whats going on?
Thanks.
