TWRP device tree for POCO X3
First checkout minimal twrp with omnirom tree:
repo init -u git://github.com/minimal-manifest-twrp/platform_manifest_twrp_omni.git -b twrp-10.0
repo sync
Then add these projects to .repo/manifest.xml:
<project path="device/xiaomi/surya" name="windeqk/android_device_xiaomi_surya_twrp" remote="github" revision="android-10" />
Finally execute these:
. build/envsetup.sh
lunch omni_surya-eng
mka recoveryimage ALLOW_MISSING_DEPENDENCIES=true # Only if you use minimal twrp tree.
To test it:
fastboot boot out/target/product/surya/recovery.img
