When you use the boot loader to load a .hex file, the previous file is replaced by the new one.  If you want to restore the default test file that comes loaded on the Axon the .hex files are available here for the Axon.  If you need to reupload the bootloader see the FAQ here.

No you don't.  Every time you load a .hex file it overwrites the previous file.
