TCL 20 Pro 5g Model T810S 256G+6G

I have a TCL 20 Pro 5G, model T810S, it is the 256G+6G one with Snapdragon 750G CPU. I haven’t seen any TCL devices supported for any ROM at all. Was actually thinking about trying to build /e/ for it myself, wondering how difficult that really is. I’m a Linux guy by trade, but I haven’t messed with rooting or ROMs for Android (or anything else) since the Cyanogenmod days. I just stumbled onto here, and the documentation looks decent, I think I can pull it off, and happy to maintain whatever I do as long as needed. I suspect once I get familiar with it I might be able to do other TCL phones too. I’ve read/heard that you can’t unlock the bootloader on these things either, but that doesn’t seem right to me, but maybe it’s a hardware protection or something? Anyway, if anyone is able to do this please let me know, or if anyone thinks I can do this please let me know.

Unfortunally there are very few resources available…

…and they also claims that:

Quite useless since their is no known way to unlock the bootloader of those devices

Have you considered the GSI in the meantime?
