MDM6610

MDM6610 in an iPhone 4S

The Qualcomm MDM6610 is the baseband chip used in the iPhone 4S.

Baseband Firmware

The firmware for the baseband chip comes in Trek-X.X.XX.Release.bbfw files (with X being the version). The BBFW file is just a renamed standard ZIP archive and contains a couple of .mbn files which are all digitally signed with a certificate from Qualcomm. Qualcomm's Senior Engineer Shital Mehta is involved with the programming of the firmware. The amss.mbn file is an ELF file:

Mac OS X file command output

file Trek-1.0.11.Release/amss.mbn 
/Trek-1.0.11.Release/amss.mbn: ELF 32-bit LSB executable, ARM, version 1, statically linked, corrupted section header size
