    I was interested in them but all the listings on AliExpress expressly said they didn't support custom firmware. I started looking into it and it seems to be something theu did after they got popular.

    Here's some info, but a lot of it is scattered around online communities: https://pocketink.io/blog/xteink-locked-or-unlocked-buying-guide/

    Thanks! I bought one months ago and flashed crosspoint at the time.

    But nice that you can still flash them via SD card even if they are USB locked. I guess it would be difficult to fully lock them given they just run an ESP32
