Baseband Bootrom Protocol

From The iPhone Wiki
Jump to: navigation, search

This is the protocol used to talk to the old, and probably the new baseband, at the bootrom level. The old bootrom didn't have a sig checking, the new one does.


2 byte length
n byte data
2 byte checksum
sends A5 on success, 5A on failure


On the iPhone 3G bootrom, the "protocol" section is pretty much identical, besides the last line, which is instead this:

sends 01 on success, FF on failure


bootrom.h in gbootloader
