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 immortalwrt-mediatek-filogic-nokia_ea0326gmp-preloader.bin BL2
3. Write new FIP:
mtd write immortalwrt-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 ImmortalWrt initramfs image using TFTP server.
6. Cut off the power and re-engage, wait for TFTP recovery to complete.
7. After OpenWrt has booted, run the following command:
This is required as there is a bug about detecting rootdisk.
sed -i 's,ubiblock,,g' /lib/upgrade/platform.sh
8. Perform sysupgrade.
