Need GL-X3000 (Spitz AX) 4.7.4 Release with Full “Network → Cellular → Band Selection” UI

Hi GL-iNet Team,

I’m running firmware openwrt-x3000-4.7.4-release on my GL-X3000 (Spitz AX), but the interface still doesn’t show Network → Cellular → Band Selection or other modem controls. I use this router as a 5 G/LTE failover behind my Unifi UDM SE, and while downloads on T-Mobile n41 reach ~140 Mbps, uploads stay below 2 Mbps. Without Band Selection I can’t manually choose LTE Bands 2/12/66 or NR Band 41 to test different anchors or SA 5 G.

Could you please share a 4.7.4 “release” build (not snapshot) that includes gl_modem and luci-app-gl-modem plus Band Selection in the GUI? A SHA256 checksum would also be appreciated so I can verify the file before flashing.

Thanks very much!
