This branch is the KY-42C TWRP 12.1 re-bring-up tree. It starts from merge commit
8c3a3eb0cc9c799ddfb88b00c7fd43d58ba11354 and audits KY-41C material before
re-enabling device-specific features.
The KY-42C prebuilt kernel, DTB and DTBO from the original KY-42C tree are kept. The first objective is a stable, non-destructive recovery with display, ADB, reboot-to-system, storage discovery and raw keypad input.
The KY-41C merge also brought in a Trustonic/Keymaster decryption stack. KY-42C uses Trustonic TEE, Keymaster 3.0 and Gatekeeper 1.0, but those imported binaries and their recovery dependencies are not assumed to be interchangeable. FBE support remains disabled until the KY-42C stack is validated directly.
The para partition is intentionally not exposed as TWRP /misc during initial
bring-up. KY-42C boot-mode state can persist there, so recovery must not modify it
until its semantics are understood and a verified restore path exists.
