Hardware specification: SoC: MediaTek MT7981B 2x A53 Flash: 128 MB SPI-NAND RAM: 256MB Ethernet: 4x 10/100/1000 Mbps Switch: MediaTek MT7531AE WiFi: MediaTek MT7976C Button: Reset, WPS/Mesh Power: DC 12V 1A Gain SSH access: 1. Login into web interface, and download the configuration. 2. Download the configration utilities: https://firmware.download.immortalwrt.eu.org/cnsztl/mediatek/filogic/openwrt-mediatek-mt7981-nokia-ea0326gmp-config-utils.tar.gz These binaries are extraced from the factory firmware, which are dynamically linked with aarch64 musl 1.1.24. To use them, you must run them under the same runtime environment, otherwise the binaries will not work properly! 3. Upload the configuration and utilities to a suitable environment. 4. Uncompress the utilities, move them to '/bin' and give them executable permisison: tar -zxf openwrt-mediatek-mt7981-nokia-ea0326gmp-config-utils.tar.gz mv mkconfig seama /bin chmod +x /bin/mkconfig chmod +x /bin/seama 5. Decrypt and uncompress the configuration: Enter fakeroot if you are not login as root. mkconfig -a de-enca -m EA0326GMP_3FE79221BAAA -i EA0326GMP_3FE79221BAAA-xxxxxxxx-backup.tar.gz -o backup.tar.gz tar -zxf backup.tar.gz 6. Edit 'etc/config/dropbear', set 'enable' to '1'. 7. Edit 'etc/passwd', remove root password: 'root::1:0:99999:7:::'. 8. Repack the configuration: tar -zcf backup.tar.gz etc/ mkconfig -a enca -m EA0326GMP_3FE79221BAAA -i backup.tar.gz -o EA0326GMP_3FE79221BAAA-xxxxxxxx-backup.tar.gz 9. Upload new configuration via web interface, now you can SSH to EA0326GMP. A minimum configuration which enabled SSH access is also provided to simplify the process: https://firmware.download.immortalwrt.eu.org/cnsztl/mediatek/filogic/openwrt-mediatek-mt7981-nokia-ea0326gmp-enable-ssh.tar.gz Flash instructions: 1. SSH to EA0326GMP, backup everything, especially 'Factory' part. 2. Write new BL2: mtd write openwrt-mediatek-filogic-nokia_ea0326gmp-preloader.bin BL2 3. Write new FIP: mtd write openwrt-mediatek-filogic-nokia_ea0326gmp-bl31-uboot.fip FIP 4. Set static IP on your PC: IP 192.168.1.254/24, GW 192.168.1.1 5. Serve OpenWrt initramfs image using TFTP server. 6. Cut off the power and re-engage, wait for TFTP recovery to complete. 7. After OpenWrt has booted, perform sysupgrade.
