GL Devs: please provide uboot and vanilla openwrt

Can GL engineers provide the latest uboot for Spitz X3000?

In addition, the device has been released for over a year but no vanilla openwrt can be found on their website:

Would any of firmware listed at this page work on X3000:, given the chip is similar
https://downloads.openwrt.org/snapshots/targets/mediatek/filogic/

No answers?!

Anyway, it seems that some X3000 (like mine) is flashed with non-functional Uboot! When I try to flash a firmware using the Uboot debrick method, the modem reboots without any changes - all my firmware’s settings are still unchanged!

Can someone test this Uboot on his X3000? And btw, that’s why I have asked for latest Uboot, although I suspect that X3000 modems are flashed during factory with a corrupt Uboot.
