We eventually worked out a way to return a Titanium 1 card back to virgin status
With these files you can : -
1. Erase any application from a Titanium 1 or 2 card.
2. Virginize a Titanium 1.03 or Titanium 1.06 card back to virgin status.
3. Write a new OS to a virgin or blank AT90SC3232c card.
All these scripts have been tested and work fine. However, you use them at your own risk
Big thanks to 007.4 !
