Version 1.21.0 | Samfw Tool

– Even on devices running Android 11 and 12 (which had just started rolling out), v1.21.0 reportedly succeeded where others failed, using a combination of test-keys and hidden dialer codes.

Version 1.21.0 was a classic “exploit roll-up” — it didn’t invent many new techniques, but it packaged existing ones so efficiently that it became the go-to tool for repair shops. The user interface remained utilitarian (almost aggressively ugly), but that’s part of its charm. No animations, no dark mode, no nonsense. Just a list of buttons that say things like “Remove FRP (New)” and “Reset Google Lock.” samfw tool version 1.21.0
