1) My phone is not officially supported by LineageOS so I will have to port it first.

2) I did not analyze LineageOS yet and how it is different from stock Android, so I need to go through complete diff.

My goal is to have an open source system that is under my full control and doesn't play tricks on my by sending telemetry or collecting forensic databases. Because now I cannot even connect the phone to Internet and it is not as useful as it could be.

I’d assume that with such a level of required inspection, you also have quite some security requirements. I’d say at that level nothing works as well as GrapheneOS (though you have to either delay security updates or accept temporarily closed source (they get access to the code only in exchange for not publishing it until X days or something) updates, thanks Google). As that currently requires a Google phone, the only way to get close to your price target would be buying it used.

I wonder if you could ask Opus 4.7 to port LineageOS for your phone. The LLM must’ve had plenty of training data from the gazillion LineageOS ports for other devices, so perhaps it might actually work (or brick your device).
