Compile

First checkout minimal twrp with aosp tree:

repo init -u https://github.com/minimal-manifest-twrp/platform_manifest_twrp_aosp.git -b twrp-12.1
repo sync

Then add these projects to .repo/manifest.xml:

<project path="device/xiaomi/umi" name="yarpiin/twrp_device_xiaomi_umi" remote="github" revision="android-12.1" />

Finally execute these:

. build/envsetup.sh
lunch twrp_umi-eng
mka recoveryimage ALLOW_MISSING_DEPENDENCIES=true # Only if you use minimal twrp tree.

Special Notes for this branch

• Device makefile in the device tree and dependencies file should use the "twrp" prefix.

• Currently, decryption on 12.1 is a work in progress (WIP). Decryption is only fully functional (i.e. works with password/PIN/pattern) on legacy Pixel devices that use weaver but do not use wrappedkey. On other devices, decryption will only work if no PIN is set in Android.

• FDE decryption is not presently supported in this branch.

• In order to successfully build in this branch, the following patch(es) will need to be cherry-picked:

  • fscrypt: wip
  • fscrypt: move functionality to libvold

To test it:
