# General setting
{% include alert.html content="In this firmware, unlike the other ones, the data must be modified in a base64-encoded file. To simplify this, you can use the following web application." alert="Info" icon="svg-info" color="blue" %}
## Web procedure
1. Get `sfp_a2_info` and paste into the form
<form id="huawei-rooted">
<div class="form-floating mb-3">
<input type="text" class="form-control" placeholder="sfp_a2_info input" name="sfp-a2-info" id="sfp-a2-info" >
<label for="sfp-a2-info">sfp_a2_info input</label>
</div>
<div class="form-floating mb-3">
<input type="text" class="form-control" placeholder="GPON S/N" name="gpon-sn" id="gpon-sn" value="" pattern="([A-Z]{4}[0-9A-Za-z]{8})|([0-9A-F]{8}[0-9A-Za-z]{8})">

</div>

<label for="gpon-password">GPON S/N in format 1234567890, 31323334353637383930 or 0x31323334353637383930, empty for not modify it</label>
</div>

<input type="submit" class="btn btn-primary" value="Calculate!">
</div>
<div class="form-floating mb-3">
<input readonly class="form-control" type="text" id="result" placeholder="sfp_a2_info result">
<label for="result">sfp_a2_info result</label>
</div>
</form>
<script>
var form = document.getElementById('huawei-rooted');
form.addEventListener('submit',(event) => {
event.preventDefault();
var fomrdata = new FormData(form);
var sfp_a2_info = fomrdata.get('sfp-a2-info');
var sfp_a2_info_arr = sfp_a2_info.split('@');
if(sfp_a2_info_arr.length > 10 && sfp_a2_info_arr[0] === 'begin-base64 644 sfp_a2_info ') {
var gpon_sn = fomrdata.get('gpon-sn');
if(gpon_sn.length == 12) {
var vendor_id = gpon_sn.substring(0, 4);
var progressive = gpon_sn.substring(4);
var vendor_id_hex = ([...vendor_id].map((elem, n) => Number(vendor_id.charCodeAt(n)).toString(16)).join(''));
gpon_sn = vendor_id_hex+progressive;
}
if(gpon_sn.length == 16) {
var hex = base64ToHex(sfp_a2_info_arr[6]);
hex = hex.substring(0,16) + gpon_sn + hex.substring(32);
sfp_a2_info_arr[6] = hexToBase64(hex);
}
var gpon_password = fomrdata.get('gpon-password');
if(gpon_password.length > 0) {
if(gpon_password.length <= 10) {
gpon_password = ([...gpon_password].map((elem, n) => Number(gpon_password.charCodeAt(n)).toString(16)).join(''));
gpon_password += '0'.repeat(20-gpon_password.length);
}
else if(gpon_password.length == 22 && gpon_password.substring(0,2) === '0x') {
gpon_password = gpon_password.substring(3);
}
if(gpon_password.length == 20) {
var hex = base64ToHex(sfp_a2_info_arr[5]);

}
}
var mac_addr = fomrdata.get('mac-addr');

mac_addr = mac_addr.replace(':','');
}
if(mac_addr.length == 12) {

}

}
});
function hexToBase64(hexStr) {
return btoa([...hexStr].reduce((acc, _, i) => acc += !(i - 1 & 1) ? String.fromCharCode(parseInt(hexStr.substring(i - 1, i + 1), 16)) : '', ''));

return [...atob(base64Value)].map(c=> c.charCodeAt(0).toString(16).padStart(2,0)).join('');
}
</script>
{:style="counter-reset:none"}
2. Transfer modified file back into variable `sfp_a2_info`, replace `<output>` with the output of web form.
```shell
fw_setenv sfp_a2_info "<output>"
```
## Temporary file procedure
1. Save `sfp_a2_info` in a temporary file
```shell
fw_printenv sfp_a2_info | sed "s/^sfp_a2_info=//" > /tmp/sfp_a2.txt
```
And print a pretty version:
```shell
fw_printenv sfp_a2_info | sed "s/^sfp_a2_info=//" | tr '@' '\n'
```
2. Setting S/N
The S/N is stored on the 6th line, for example `4857544311223344` (where `48575443` is the HEX encoding of `HWTC`):
```
AAAAAAAAAAJIV1RDESIzRP///////////////////wAAAAAAAAAAAAAAAAAA
00000000000000024857544311223344ffffffffffffffffffffffffffffff0000000000000000000000000000
```
The entire S/N, including the PON ID, is encoded first in hexadecimal and then in base64
3. Setting PLOAM Password
The PLOAM Password is stored on the 5th line, for example (`1234567890`):
```
ffffffffffffffff00021437d77db7df7e37e77eb7ef7f37f77d00000000000000000000000000000000000000
//////////8AAhQ31323334353637383930AAAAAAAAAAAAAAAAAAAAAAAAA
```
The entire PLOAM, is encoded first in hexadecimal and then in base64
4. Setting MAC Address
The MAC Address is stored on the 9th line, for example (`48:57:02:da:be:ef`):
```
AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAASFcC2r7vAAAAAAAAAAAAAAAAAAAA
000000000000000000000000000000000000000000000000485702dabeef000000000000000000000000000000
```
5. Transfer the modified file back into variable `sfp_a2_info`
```shell
fw_setenv sfp_a2_info $(cat /tmp/sfp_a2.txt)
```
## Reviewing and testing
After rebooting, check whether the new variables have been saved correctly:
```shell
fw_printenv nPassword
fw_printenv gSerial
fw_printenv ethaddr
```
## Checking whether the connection with the OLT was successful (O5 state)
```shell
onu ploamsg
```
# Disabling dying gasp
```shell
fw_setenv nDyingGaspEnable 0
```
