all “modern” baseband processors (MTK, Qualcomm etc) have ROM bootloaders which perform cryptographic verification of downloaded fw images, and will not boot any image that has not been signed by the secret key corresponding to the public key whose hash is burned into OTP (one-time programmable) fuses right in the modem chip silicon! The FSF term for this freedom-robbing feature is tivoization.
