What is it that you plan to do? AmonRa is a custom recovery used for flashing after-market ROMS developed for the phone.
It requires prior rooting of the phone. AmonRa does not contain any 'system' files required by Android for normal use.
If you still require AmonRa, search & you will find it in this forum.
