Patch Management

This device tree includes custom patches for TWRP functionality (FBE decrypt, staged restore, UI improvements).

Apply patches and build

Patches are automatically applied during the build process:

export ALLOW_MISSING_DEPENDENCIES=true; . build/envsetup.sh; lunch twrp_pa3q-eng; mka vendorbootimage

Revert all patches

device/samsung/pa3q/patches/revert-patches.sh

Note: Patches are idempotent—building multiple times is safe. The build system only applies unapplied patches.
