In this phase, Explore custom ROMs and become familiar with them.
There is a lot to mention. But I am sure you will learn all the things eventually from the community.

4) Build a custom ROM for your device
You are a pro user now, let's do something more.

To build an Android ROM, you need a good specs PC.
Check the requirements: source.android.com/docs/setup/sta…
Most people (like me) can't have a machine that meets the requirements.
I got you.

What you can do about that?
-> Try to get a free trial from services like Google Cloud Platform (GCP), Azure or AWS. Then create a virtual machine (VM)
-> Ask for help from your community friends. They may help you.

-> There are some low-cost paid server (VM) providers around the telegram android communities. (Personally no experience)
-> Try to upgrade your laptop/PC with a good amount of RAM (more than 16 GB)

Now you have the machine to build.
-> How to build?
I ain't gonna write it about in detail since there are a lot of guides out there. (a thread for another day)
Lineage wiki (device-specific): wiki.lineageos.org/devices/onclit…
Official doc: source.android.com/docs/setup/sta…

From the lineage wiki, up to this wiki.lineageos.org/devices/onclit… are common for all devices.
For the next step
-> You have to download/clone your device sources - Device config tree, kernel tree and vendor tree.
-> Lunch your device
-> Start the build

-> I recommend you get the details from your community. Learn from them. Get help from them. (no spoonfeeding)
-> Build errors: Try to get help after trying something yourself. Don't go straight to the community without any try. (a thread for another day)
