X4 Classic (a.k.a. X4 V2) — Xteink Unlocker not supported yet; SD flashing doesn't work (CN, USB-locked)

Device: Xteink X4 Classic (ESP32-S3 model, formerly "X4 V2") — Chinese variant, USB flashing locked
Stock firmware: XTOS V7.1.21
Goal: flash CrossPoint Reader

Thanks for the great work on the firmware and unlocker! I have an X4 Classic and I'm stuck:

SD card method doesn't work: update.bin on SD root + holding Power+Up does nothing. As with the X4 Pro, SD flashing isn't supported on the Classic.
Xteink Unlocker (OTA): tapping "Check for Updates" the device says it "only accepts encrypted OTA files" — consistent with the X4 Pro's encrypted_v1/.xota OTA system.

I noticed CrossPoint firmware already lists the X4 Classic, but the Xteink Unlocker doesn't support it yet. Since USB is locked and SD won't work, the unlocker is my only path. Just checking: is X4 Classic support in the unlocker planned? Happy to provide traffic-capture logs / test whenever a build handling the X4 Classic is available.
