So here's record of my journey...
My wife's phone was left, forgotten on top of our car, and later the kid drives off to visit someone. Phone's missing for a day, and Sprint family locator keeps saying that it's in the middle of a busy street just north of us, but the error is large enough that we keep looking at home. But turns out the phone was in the middle of the busy street north of us
Had been run over, front glass completely spider webbed, buttons a little squished on rashed and spread into five peices (three Otter Box chunks and battery cover and phone somehow with battery still in it). But it still completely works!! Screen swiping, calls, everything! A testament to HTC and the Otter Box Defender series protective cover.
So now I have to de-Froyo the thing (also had Firerat's partition mod installed), so we can take it to a retailer.
First thing.... made a nandroid.
I've HTC Sync installed on our Win7 laptop.
I ran this RUU:
[GUIDE] How to Root Sprint 2.1 Release for CDMA Hero - Page 2 - xda-developers
I ran this RUU:
HTC Mobile Phone Support - HTC Hero? (Sprint) - Downloads
and I kept getting:
Error[140]: BOOTLOADER VERSION ERROR
The ROM Update Utility cannot update your Android phone
Please get the correct ROM Update Utility and try again
Thinking it was maybe Firerat's partition mod messing with me, I boot into recovery, format everything (all seven things, but not sdcard
) and try to restore a older, oem partitioned nandroid, and it gives me 'cache log' error of not enough space. Then I try the oldest nandroid, 2.1 stock/rooted (after formating everything) same error. But I can still restore the nandroid I had just made. But the RUUs still wouldn't work 
(so maybe it didn't survive the crash completely)
Fortunately in my journey of research I found this:
Thank you tehdarknight!
and this
Thank you jasonmaloney!
Using jasonmaloney's process I was able to get into fastboot and flash tehdarkknight's RUU zip.
NOTE: my adb.exe is in directory:
c:\android\platform-tools
the "HERCIMG.ZIP" had to be in there too.
I didn't see a similar thread in the Sprint Hero section here, so there you have it.
