Silly idea maybe, but would it be possible to port osmocom-bb for mediatek/intel/qualcomm BBP and replace the current firmware with open one?
theoretically possible, yes.
I presume it will be a tremendous amount of work, no doubts, but apart from that, is it theoretically and technically possible? Given root and/or hardware acces of course, we do not need to preserve the old firmware or exploit the update process (ie. if specific cert signature is needed for bbp-soc firmware update)
The biggest challenges, from my point of view, are:
* using phones that don't use secure/authenticated boot for the BBP, or those where the certificates have leaked and/or exploits are known * finding significant enough amount of leaked sources or documentation and/or doing the reverse engineering required to understand how to talk to the DSP and/or related peripherals * finding the time to work on the protocol stack beyond classic 2G which is currently implemented in OsmocomBB.
