This ONT supports dual boot, as visible from the presence of `kernel1` and `kernel2`, 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
{% include alert.html content="Commands have been tested on V2 HW rev. on OpenFiber firmwares" alert="Note" icon="svg-info" color="blue" %}
## 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"
reset facTelnetSteps:
reset OK!
facStep 1:
OK!
facStep 2:

```
## 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

## Querying a particular OMCI ME
```sh

```
This command will print the following output:

# GPON/OMCI settings
## Setting ONU GPON Serial Number
{% include alert.html content="Both S/N and VID have to be changed. 2176 is for the VID (first 4 letters of the S/N) and 2177 is for the last 8 digits of the S/N" alert="Note" icon="svg-info" color="blue" %}
```sh
setmac 1 2176 ZTEG
setmac 1 2177 AABBCCDD
```
## Setting ONU GPON PLOAM password
{% include alert.html content="The PLOAM password is stored in the ASCII format." alert="Note" icon="svg-info" color="blue" %}
This can be done easily via the web UI. To do it via the shell use:
```sh
setmac 1 2181 1234567890
setmac 1 2178 1234567890
```
# Advanced settings
## Backing up ONT Paritions for HW/SW Version Mod
This step is suggested if you want to replace firmware on your ONT to spoof HW and SW version:
Needed tools:
- Linux VM or WSL with Python >3.3
- [ZTE Telnet enabler](https://github.com/douniwan5788/zte_modem_tools)
- TFTP server
The first step is to login over telnet with `zte_factroymode.py`, then execute ALL these commands for a full backup:
**Go to `/tmp` folder to create tmp files**
```sh
cd /tmp
```
**Dump and transfer all mtd **
In the following commands, 192.168.1.2 is the IP of the machine running the TFTP server, change it as needed.
```sh
cat /dev/mtd1 > u-boot.bin && tftp -l u-boot.bin -r u-boot.bin -p 192.168.1.2 && rm u-boot.bin
cat /dev/mtd2 > others.bin && tftp -l others.bin -r others.bin -p 192.168.1.2 && rm others.bin
cat /dev/mtd3 > parameter_tags.bin && tftp -l parameter_tags.bin -r parameter_tags.bin -p 192.168.1.2 && rm parameter_tags.bin
cat /dev/mtd4 > wlan.bin && tftp -l wlan.bin -r wlan.bin -p 192.168.1.2 && rm wlan.bin
cat /dev/mtd5 > usercfg.bin && tftp -l usercfg.bin -r usercfg.bin -p 192.168.1.2 && rm usercfg.bin
cat /dev/mtd6 > middle.bin && tftp -l middle.bin -r middle.bin -p 192.168.1.2 && rm middle.bin
cat /dev/mtd7 > kernel1.bin && tftp -l kernel1.bin -r kernel1.bin -p 192.168.1.2 && rm kernel1.bin
cat /dev/mtd8 > kernel2.bin && tftp -l kernel2.bin -r kernel2.bin -p 192.168.1.2 && rm kernel2.bin
cat /dev/mtd9 > rootfs.bin && tftp -l rootfs.bin -r rootfs.bin -p 192.168.1.2 && rm rootfs.bin
```
## Changing region code
{% include alert.html content="Be aware that changing the region code may break features such as PPPoE depending on your ISP" alert="Note" icon="svg-info" color="blue" %}
ZTE has created various region codes that load default values based on the local ISP. This configuration can be changed using this command:
```sh
upgradetest sfactoryconf X
```
Where X is the number of supported regioncode into file `/etc/init.d/regioncode`, here is an example from OpenFiber `V2.0.10P7N2` firmware:
```sh
# cat /etc/init.d/regioncode
19:Turkey
65:FTOrange
116:Tescali
139:Multilaser
188:HollandKpnSfu
198:Manufacture
2010:Cetin
```
# Random notes
- The F2801S reads the software version exposed through the gpon_omci deamon from each kernel partition header, so the only way to spoof this parameter is to change the version in the header and recalculate CRC, otherwise the bootloader will refuse to load the image

- [ZTE Telnet enabled](https://github.com/douniwan5788/zte_modem_tools)

[^1]: It may be possible to flash an alternative firmware to avoid running the `zte_factory.py` script each time.
[^2]: Credentials are randomly generated by zte_factroymode.py. They don't survive at reboot
