From what I know holding the ERASE button erases the current contents of flash (see my warning above) and invokes the (serial) bootloader on these older ARM SoC's. It would seem that is working but the download doesn't even though Samba thinks it does. I'd double check your connections (RXD/TXD reversed at one/both ends?).

The HP-15C CE firmware isn't protected (but could be) so the ERASE button just starts the bootloader. Reflashing and VoyagerSave work in XP/Win7 virtual machines (VM's) for me.
