Creating the Device Tree A device tree consists of several (makefile) files that define the build parameters. BoardConfig.mk: The version TWRP 3
This is the most critical file. It defines the architecture (CPU), kernel command line, partition sizes, and specific TWRP flags (e.g., TW_THEME := portrait recovery.fstab: This tells TWRP where partitions like are located so it can mount them correctly. omni_device.mk:
Inherits the core recovery features and sets the product name and brand. 4. Building the Recovery Once your tree is placed in device/

It looks like you're looking for content related to TWRP (Team Win Recovery Project) and the numbers 3021 and 2021.
There’s a strong chance this is a typo for TWRP 3.2.1 (released around 2017), or you’re looking for TWRP releases/builds that happened in 2021. There is no standard TWRP version "3.0.21" or "3021".
