If it has GSM/LTE/CDMA/etc baseband processor with closed implementation, assume it has remote root backdoor. Samsung has already been caught.
osmocombb tried to solve this. That project is essentially dead.
- lurker12390879 9y agoLibrem 5 is a partial solution because the baseband has no access to the system.
- nyargh 9y agoStill has DMA, no?
- kogepathic 9y agoNo, the baseband radio will not be connected to the SoC via DMA. They are proposing to use an external baseband with a USB or UART interface to the main SoC and a kill switch. https://forums.puri.sm/t/level-of-freedom-of-librem-phone-especially-gsm-mdule/1316/2 https://forums.puri.sm/t/level-of-freedom-of-librem-phone-es...
