Upon deeper investigation, the generic scatter file had a preloader start address off by exactly 0x2000 bytes. This overwrote the first few kilobytes of the boot partition, corrupting the ARM TrustZone (TEE) header. The device was fully bricked. Recovery required desoldering the eMMC and using a programmer to rewrite the raw flash image—a $150 repair for a $130 phone.
