BVR boardview for the iPhone 7 Plus logic board in its Qualcomm modem version, 372 KB. The 7 Plus was built with either a Qualcomm or an Intel baseband, and the layouts around the modem differ, so this file applies to Qualcomm-equipped boards only. Load it in a boardview program supporting BVR to locate parts, follow nets and find test points when chasing no-service, audio IC or short-circuit faults. The (1) in the name suggests a duplicate copy; check the model and modem on the board before use.
