This ONT supports dual boot, as visible from the presence of `kernel0` and `kernel1`, which contain the rootfs.
The boot images can be swapped with the following command:
```sh
upgradetest switchver X
```
Where `X` can be `0/1`, based on the image you want to boot from.
You can also clone the currently running image into the other slot using this command:
```sh
syn_version
```
# Use
## Enable Telnet
{% include alert.html content="This is an external script ([ZTE Telnet enabler](https://github.com/douniwan5788/zte_modem_tools)), use at your own risk! Credentials don't survive at reboot!" alert="Note" icon="svg-info" color="blue" %}
```sh
python3 zte_factroymode.py --user admin --pass admin --ip 192.168.1.1 --port 80 telnet open
```
You should get this output and credentials to login over telnet:
```sh
trying user:"admin" pass:"admin"

## Enable console redirection
To see omcidebug messages on telnet, execute this command (just the first time of each connection):
```sh
redir printf
```
# GPON ONU status
## Getting the operational status of the ONU
To check the connection status, use the following command:
```
gpontest -gstate
```
`[gpontest] gpon state is [O5]` for O5 state
## Getting OLT vendor information
```sh
sendcmd 132 omcidebug showmedata 131
```
This command will print the following output:
```sh
