when all else seems to fail, we've had good luck with the following explicit (and somewhat lengthy) sequence:

0) Turn off all power tools, milling machines, Van de Graaff generators, etc. Use a known good Black Jag (with CAN ID set to something other than 1) as a bridge and use known good cables/terminators...
1) Hold the Tan Jag's "user" button down.
2) cycle power
3) continue holding "user" button for 60sec (not sure what's actually required)
4) release the "user" button
5) Connect BDC Comm (or re-numerate)
6) Select "Recovery"
7) Select the binary for a Tan Jag
8) BDC Comm will update the Tan Jag, wait for it to complete
9) Re-numerate the CAN bus and you should have your Back Jag at its CAN ID and the Grey should be at CAN ID 1.
10) Set the new CAN ID for the Tan Jag
