I have Amon Ra's bootloader installed on my Nexus One, running a Cyanogen 2.1 rom. I want to update my radio using this bootloader, but the radio image I downloaded has a .img suffix, and that bootloader only lets me install .zip files. Should I just rename my *.img radio image to *.zip and then install it as usual? I think the answer is probably "yes", but I want to double-check before I try this. Thanks in advance. PS: if the answer is indeed "yes", then does the renamed radio image have to be update.zip, or any it be anything-I-want.zip? PPS: I am using MacOSX, and I haven't been able to find a fastboot executable for that OS. .
