I'm not sure which you are talking about.  The broken RES360, or the RES720?

I have a firmware update that is supposed to fix my RES 360, but I'm
woorkong on the very different RES 720 right now.  I'll fuss with tthe
new firmware later.  The RES720 is comong along.  Most of the TPV stuff
works, but the SKY stuff is WIP.

The RES360 has firmware from 2006, so not new at all.  It did sit on a
stocking shelf for 10 years before I got it.  There have been several
firmware updates for major problems since 2006.

Nope.  Week is stuck at 2048.  It is the TOW that is negative.

Nope.  It actually computes the lat/lon/alt and SKY view perfectly.
Since it could not increment the week, it went backwards in TOW.  Thus
coming to a working time solution.
