I am having great touble getting version 3 of the firmware onto my RCX.
It seems to fail after the upload has finished, while "unlocking"

C:\lejos\bin>firmdl.bat
read firmware srec
  100%
Segment 0: length = 14578
Segment 1: length = 2940

Firmware downloaded
Unlocking firmware
Unlock firmware failed: Tower error: no response from rcx.

I have tried downloading a programing onto the RCX just incase the firmware write was successful, but it obviously was not:

C:\lejos\bin>lejosdl.bat ../check/DistributionSmokeTest
.bin
read binary
  100%
download binary
Loading native libs
download program
Tower error: bad response from rcx
Please make sure RCX has leJOS firmware and is in range.
The firmware must be in program download mode.
Turn RCX off and on if necessary.

After trying to load the leJOS firmware, the RCX seems to be back to "boot mode".
I can download the Official lego firmware onto the brick at any time without problems, but lejos is proving a real problem.

Any Help would be much appreciated.
