This value can be changed using the web interface.

Getting/Setting OMCI software version (ME 7)

The software version must be changed by directly modifying firmware by using the patches found in the wiki’s page about the Nokia G-010-A ONT and then adding a folder 0001_swversion that contins a file with the following content:


set -e


echo "Changing to software version desidered"
sed -i s/3FE46398BGCB22/3FE45655BOCK99/g "$ROOTFS/usr/etc/buildinfo"

Where 3FE46398BGCB22 is the current software version and 3FE45655BOCK99 the desired software version

Getting/Setting OMCI hardware version (ME 256)

ritool set HardwareVersion 3FE47211EGAA

Transferring files to the stick

# scp rootfs.bin root@

Backup of all partition

Make a backup of all partitions, an easy way is to run these commands:

  • On the stick run:
    cat /proc/mtd
  • For each mtdX run this command in the lantiq shell:
    cp /dev/mtdX /tmp

And in the computer shell:

scp ONTUSER@ ./

Checking the currently active image
