PRC to force card 1 reflash upon card insertion/appearance?

Archived from groups: comp.sys.palmtops.pilot (More info?)

I have a ThinModem+ that whose memory has become corrupt. Normally this is
no big deal because I can just reflash the original software but this
corruption is strange in that as soon as ANY button is pressed (even on a
no-notify restart), the OS crashes. Here is as far as I can get:
Reprogram Hard Button to possibly useful PRC (FileZ, ThinModemUpdater, etc.)
Insert Card (crash ensues).
Reset Prism (holding down rocker for no-notify).
As soon as screen "blinks", push reprogrammed hard button.
Now I am running a useful app and have avoided a crash.

However, In order to FORCIBLY reflash, the ThinModemUpdater requires that I
hold the down rocker while I tap "Update". As soon as I tap the "down"
button, the OS crashes.

If I use Filez to examine card 1, it too crashes.

So what I need is something that will FORCIBLY reflash card 1 with ANY
software at all without the user having to hit any buttons first. I can
launch an app without crashing but cannot tap the screen without crashing.
Is there anything that can do this? Is there any source code around for
reformatting card 1 (I could compile my own app)?

If I can reflash anything, then, presumably, I can go back and run
ThinModemUpdater to foricbly reflash again to put it back the way it should
be.

P.S. It has nothing to do with hacks or any other software, I have tried a
hard reset (total memory wipe) and the module still induces crashes upon
insert or screen tap.
