I'm about to order ZBT-WG1608 with has a MT7721 CPU it only run old 17.01 but they say they reprogrammed it
... our device can support openwrt firmware. But it's not opensource firmware. they are reprogrammed buy our R&D team. And our openwrt firmware version is 17.01 near to 17.01.2
Can I update it to v.19?
