18xjul08/BrickOS_autobuild — reverse-engineered prompt

Build me a simple automation project called BrickOS that can take a Xiaomi China ROM and rebuild it into a cleaner custom ROM. I want it to remove unwanted preinstalled apps, add Google services, add multiple languages, fix notifications that usually break on China ROMs, and include the KariOS toolbox for deeper system tweaks. Please make the process easy to run from scripts, with a setup step, a build step, a packing step, and an upload step, so I can change basic settings in one config file instead of editing code everywhere.

Keep it practical and beginner friendly. Add clear prompts and logs so I know what the script is doing, and make the README explain what files I need, where to put the ROM, and how to run everything. If you need exact Android ROM tooling details, look up current docs online.
