Technical evolution Early unlock tools relied on straightforward relationships between device identifiers (e.g., IMEI, MEID, or serial numbers) and unlock codes. Manufacturers sometimes used deterministic algorithms—mathematical transformations of an IMEI or a combination of device parameters—to generate a network unlock code. Tools that implemented these transforms (often in simple lookup tables or polynomial calculations) could produce codes quickly and reliably.
