Below is an optional Cherry-pick For the device if you want to add it

Make a directory named local_manifest under .repo, and create a new manifest file, for example local_manifests.xml and then paste the following

<?xml version="1.0" encoding="UTF-8"?>
<manifest>
  <project path="device/oneplus/lemonades" name="ApexLegend007/twrp_device_oneplus_lemonades" remote="github" revision="android-12.1" />
</manifest>

Sync the sources with

repo sync -j$(nproc --all)

To compile Recovery, execute this command:

. build/envsetup.sh; export ALLOW_MISSING_DEPENDENCIES=true; export LC_ALL=C; lunch twrp_lemonades-eng; make -j$(nproc --all) adbd recoveryimage

To test it:

# To temporarily boot it
fastboot boot out/target/product/lemonades/recovery.img 

# Since 9R has a separate recovery partition, you can flash the recovery with
fastboot flash recovery recovery.img
