This TWRP automatically detects the device region and updates the device code name "ulysse"
First checkout Minimal TWRP with OmniROM Tree:
repo init -u git:https://github.com/minimal-manifest-twrp/platform_manifest_twrp_omni.git -b twrp-9.0
repo sync
And execute these:
export ALLOW_MISSING_DEPENDENCIES=true # Only if using Minimal TWRP Tree
. build/envsetup.sh
lunch omni_ulysse-eng
mka recoveryimage
Testing it:
fastboot boot out/target/product/ulysse/recovery.img
Flash it via fastboot:
fastboot flash recovery recovery.img
Or use Official TWRP App to install it.
