Where to even start?

So I found the phone I was looking for, funny how as soon as I complain online it remembers it’s supposed to exist and re-enters the physical plane. It was in a crate with some old documents, idk how it got there.

I’d like to build a custom OS for it, specifically I wanna build PostmarketOS or Ubuntu Touch, genuinely I don’t care I just want real linux and I can go from there.

I’m not sure where to even start. Nobody has built custom ROMs for this device so far, the Razr 50/Razr 2024 on account of the Dimensity 7300x SoC it’s sporting. I’ve reached out to Mediatek for drivers and their resounding silence rang through with a deafening “get fucked”, so I gotta build my own.

I know I could technically just rip apart the stock rom for the bits and pieces I need, but then I wouldn’t be allowed to release my rom to the public since it would contain proprietary code to which I don’t own rights.

So I need to make the drivers myself, but like, I don’t even know where to start. I’ve never written a driver before. Hell I’m only just learning C, I’m like, not a great programmer yet. Which is fine.

So how do I start making a driver? I bet I don’t have the right tools. I bet I need all kinds of kit. DMs appreciated.

Love y’all,
Nora
