You shouldn't ERASE a working 34S. Instead do the following:

  1. Press ON+STO+STO to save RAM to flash.
  2. Press ON+D to unlock the next step.
  3. Press ON+S+S to enable SAM-BA boot mode.
  4. Connect the calculator and arm MySamba.
  5. Turn ON the calculator and start the transfer.
  6. Reset the Calculator when done.
  7. On power on the saved RAM contents will be restored.

The library will be replaced by what comes with the flash image but the RAM contents will be preserved.
