To understand the difficulty of unlocking the S9 Snapdragon, one must first understand Samsung’s regional segmentation. Historically, Samsung releases Galaxy devices in two variants: the Exynos model (for markets like Europe and Asia) and the Snapdragon model (for the USA, China, and Latin America). While the Exynos variants generally come with an official "OEM Unlocking" toggle in the developer options, allowing for a relatively straightforward bootloader unlock, the Snapdragon variants are frequently locked down tight.
