Hi guy

Hi fachos,

your firmware saved my mr6400. cellular is working now.

but i wonder why 23.05 openwrt doesn't work on this device. i installed qmi by the official guide, it is in "connected" state, there is some data in TX but none in RX.

also this device has a very small disk size :frowning:
