Thanks, do you know if this comment is true still?:
> As of the latest models, XTEINK has started to lock down the firmware to prevent users from installing Crosspoint. So, if you're reading these reviews, beware: the thing that a lot of people bought this for is going away soon.
> Some Xteink units purchased from third-party stores (e.g. AliExpress) ship with USB flashing locked from the factory. If your device is locked, you will need to use the Xteink Unlocker tool available at https://crosspointreader.com/#unlock-tool before you can flash CrossPoint.
Kind of. There's an "unlocker" that just spoofs their OTA endpoint to flash custom firmware because xteink decided to not implement TLS validation, though they could theoretically change that at any point.
Xteink also claims that non-domestic versions of their devices sold by their "official" store are unlocked, but there's been a bunch of reports that that's not always the case (...along with devices arriving with broken screens, not arriving at all, or the wrong device showing up).
I stumbled upon the Biscuit fork of Crosspoint, which basically make it a tiny covert pentest tool while also keeping ereader functionalities. To be seen if it will keep up with the OG Crosspoint.
