Verify CID/EXT_CSD for eMMC or UFS descriptors/LU geometry/RPMB for UFS before donor substitution.
A matching part number or package does not prove donor compatibility. Before replacement confirm the ball map, VCC/VCCQ, protocol generation, capacity geometry, DRAM training (MCP), CID/EXT_CSD or UFS descriptors, RPMB and OEM provisioning.
