Installation
------------
1. Connect to the router using ssh (user: admin, pass: web interface
password)
2. Make mtd backup:
cat /dev/mtd0 | gzip -1 -c > /tmp/mtd0_spi0.0.bin.gz
cat /dev/mtd1 | gzip -1 -c > /tmp/mtd1_BL2.bin.gz
cat /dev/mtd2 | gzip -1 -c > /tmp/mtd2_u-boot-env.bin.gz
cat /dev/mtd3 | gzip -1 -c > /tmp/mtd3_Factory.bin.gz
cat /dev/mtd4 | gzip -1 -c > /tmp/mtd4_FIP.bin.gz
cat /dev/mtd5 | gzip -1 -c > /tmp/mtd5_ubi.bin.gz
3. Download mtd backup from the /tmp dir of the router to your PC using
scp protocol
4. Upload OpenWrt 'bl31-uboot.fip', 'preloader.bin' images to the /tmp
dir of the router using scp protocol
5. Write FIP and BL2 (replace bootloader):
mtd write /tmp/openwrt-mediatek-filogic-netis_nx31-bl31-uboot.fip FIP
mtd write /tmp/openwrt-mediatek-filogic-netis_nx31-preloader.bin BL2
6. Place OpenWrt
'openwrt-mediatek-filogic-netis_nx31-initramfs-recovery.itb' image on
the tftp server (IP: 192.168.1.254)
7. Erase 'ubi' partition and reboot the router:
mtd erase ubi
reboot
8. U-Boot automatically boot OpenWrt recovery image from tftp server to
the RAM
9. Upload OpenWrt 'sysupgrade.itb' image to the /tmp dir of the router
(IP: 192.168.1.1) using scp protocol
10. Connect to the router using ssh and run:
sysupgrade -n openwrt-mediatek-filogic-netis_nx31-squashfs-sysupgrade.itb
Return to stock
---------------
1. Unpack stock BL2 and FIP partitions backup
2. Upload stock BL2 and FIP partitions backup to the /tmp dir of the
router using scp protocol
3. Connect to the router using ssh and run:
apk update && apk add kmod-mtd-rw
insmod mtd-rw i_want_a_brick=1
mtd unlock BL2
mtd unlock FIP
4. Restore backup:
mtd write /tmp/mtd4_FIP.bin FIP
mtd write /tmp/mtd1_BL2.bin BL2
5. Erase ubi and reboot:
mtd erase ubi
reboot
6. Power off the router
7. Press Reset button and power on the router. Release the button after
~10 sec
8. Navigate to U-Boot recovery web server (http://192.168.1.1/) and
upload the OEM firmware
Recovery
--------
1. Place OpenWrt
'openwrt-mediatek-filogic-netis_nx31-initramfs-recovery.itb' image on
the tftp server (IP: 192.168.1.254)
2. Press “Reset” button and power on the router. After ~10 sec release
the button.
3. Use OpenWrt initramfs system for recovery
