Installation
-------------------Install openwrt image-------------------------------:

Set a static ip on the ethernet interface of your PC. (ip address:
192.168.1.254, subnet mask:255.255.255.0) .

Download the OpenWrt uboot image
(openwrt-mediatek-filogic-snr_cpe-ax2-bl31-uboot.fip).

SSH/SCP opened by default on the stock firmware (3.0.1).
Username: Admin, default password: Admin. Check it on the bottom of
the router.

Copy uboot image using SCP (WinSCP) to /tmp dir on SNR-CPE-AX2.

Download recovery file.
openwrt-mediatek-filogic-snr_snr-cpe-ax2-initramfs-recovery.itb.

Copy the recovery image to a TFTP server reachable at 192.168.1.254/24.

Open ssh shell to the SNR-CPE-AX2.
Run commands:
mtd write \
/tmp/openwrt-mediatek-filogic-snr_snr-cpe-ax2-bl31-uboot.fip FIP
reboot

Wait until recovery boot.
Open web 192.168.1.1 and do sysupgrade by
openwrt-mediatek-filogic-snr_cpe-ax2-squashfs-sysupgrade.itb
