I assume you are saying that you were successful in asserting RSTCONF 
and programming the HRCW back in.
* Is it the _correct_ HRCW?  Do you know what it was previously?
* Did you _power cycle_ the board with RSTCONF deasserted? (the HRCW 
only is read on a _power cycle_)

My experience (not with the Rattler) is that boards don't run well with 
RSTCONF asserted.  In my experience, I assert RSTCONF, program the HRCW 
(and optionally u-boot), and then _power cycle_ the board.  At that 
point, the board should be functional enough to program u-boot (or 
whatever) into it, reset, and run.
