 # Useful Commands
 
+{% include alert.html content="Some variables are write-protected, you need to unlock them before proceed" alert="Info" icon="svg-info" color="blue" %}
+
+Use the following command to unlock write-protected variables:
+
+```sh
+# nv setenv ProtectEnv 0
+```
+
+## Getting/Setting the ONT's S/N
+
+{% include alert.html content="If your serial number has letters after the Vendor ID (e.g. ZTEGAAA01234), put them in lower case (e.g. ZTEGaaa01234)" alert="Info" icon="svg-info" color="blue" %}
+
+```sh
+# nv setenv GponSn ZTEGaaa01234
+```
+Reboot the ONT to apply any changes
+
+You can check if the serial number was correclty changed using the following command:
+
+```sh
+# diag gpon get serialnumber
+ZTEGaaa01234
+```
+
+## Changing the Hardware Version
+
+```sh
+# nv setenv HV G2110CE2V1D0
+```
+Reboot ONT to apply the change
+
+## Changing the Equipment ID
+
+```sh
+# nv setenv ProdName FT-G2110C-2.5G
+```
+Reboot ONT to apply the change
+
+## Changing the IP address
+```sh
+# /etc/scripts/flash get LAN_IP_ADDR
+LAN_IP_ADDR=192.168.1.1
+# /etc/scripts/flash set LAN_IP_ADDR 192.168.1.1
+ ```
+
+## Getting/Setting the ONT's PLOAM password
+
+{% include alert.html content="The PLOAM password is stored in ASCII format" alert="Info" icon="svg-info" color="blue" %}
+
+```sh
+# /etc/scripts/flash get GPON_PLOAM_PASSWD
+GPON_PLOAM_PASSWD=AAAAAAAAAA
+# /etc/scripts/flash set GPON_PLOAM_PASSWD AAAAAAAAAA
+```
+Looks like Genexis has also included an U-Boot variable to store the PLOAM. On currently known firmwares (5.6.1 and 5.7.0) it is not read by the `omci_app` daemon.
+If you want to be future proof, put your PLOAM also on U-Boot env using the following command in the OS shell:
+
+```sh
+# nv setenv ploampwd 1234567890
+ploampwd=1234567890
+```
+
+## Spoofing firmware version
+
+{% include alert.html content="To change this data you need to upload a modified firmware. Do it at your own risk!" alert="Warning" icon="svg-warning" color="red" %}
+
+- Download the modified firmware from [here](https://mega.nz/file/yspFRTJT#JjeDS7NwLZxCzFklQGMJVIuPawo8utQRGbMGEXQv84M) md5:  `91946ad8aada2e469b7fff1d38ee7474`
+- Logon on the OS shell of the ONT and run this command: `iptables -F`
+- Open a web browser and go to `http://192.168.1.1/upgrade.asp` or `http://192.168.100.1/upgrade.asp`, enter the same credentials used for telnet session, select the modified firmware and click on `Upgrade`
+- Once the upgrade is done and you are able to reach the ONT via telnet, log back in and run these commands to change the firmware version on both banks:
+
+```sh
+# /etc/scripts/flash set OMCI_OLT_MODE 3
+OMCI_OLT_MODE=3
+# nv setenv sw_custom_version0=V6.0.10N14
+# nv setenv sw_custom_version1=V6.0.10N14
+```
+
+Reboot the ONT and check if the version was correctly applied with this command (take a look at the `Version` field):
+
+```sh
+# omcicli mib get 7
+XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
+SWImage
+XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
