Upstream uses a different filename, so lets rename our downstream
mt7981.dtsi to mt7981b.dtsi and update the device tree of all
MT7981 boards accordingly.
This is to prepare for the switch to Linux 6.12 which is going to
use the upstream mt7981b.dtsi (plus some patches on top).

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
