Unlock G-2425G-A router running on latest firmware

Note: Tested for Nokia router G-2425G-A running on firmware 3FE49362JJIJ50.

Use this script to decrypt your configuration file. This script has been updated for latest firmware (3FE49362JJIJ50).


Source

All the steps to decrypt the config files has been already discussed in other posts as well, kindly follow them.

1) After decrypting the config file, open the generated xml file in a text editor.
2) Search for TelnetSshAccount section and write username as ONTUSER and password as "anyrandompassword" (remember this password for future).
3) Enable ONTUSER to drop into busybox instead of vtysh by setting LimitAccount_ONTUSER to false. Go to LimitAccount_ONTUSER section and change that option to FALSE.
4) Encrypt the config file again using the same script and import in your router (remember to enable telnet in Security --> Access Control --> LAN).
5) Now use any tool to access telnet, I have used windows powershell (you can enable telnet in windows additional features).
6) In Windows PowerShell write; telnet --> o --> 192.168.1.1

Username: ONTUSER
Password: your password from STEP 2

7) Now in shell write ---> ritool set OperatorID ALCL

After this step you have enabled root access. Login to your router to check everything has been unlocked.

Now hard reset from back of the router is recommended to enable editing any WAN settings but before that remember to take a backup of your configuration and wan settings.

8) After hardreset the router's gateway will default to 192.168.1.254 and username and password will change to AdminGPON and ALC#FGU respectively.

can anyone share a fast.com speedtest result showing the pings using Nokia g-2425g-a?

@iYuvrajMehta I am on 100/100 connection.

@shibam.sar to relock you have to use command ritool set OperatorID BRTI then if you want, you can reset the router.

I have unlocked the router , everything else is fine , i can delete and create WAN profiles of PPPoE and IPoE and it connects , however i cannot get the bridge mode activated on any port . When i connect the LAN port from the ONT to my Asus AX86U Pro router it just says network plug is disconnected .

 

[user848654]

@sk7411 yes, that's a known behavior, I also use Asus router, on the WAN page scroll down, under "Special Requirement from ISP", set "Enable VPN + DHCP Connection" to "No". And bridge mode won't work just by unlocking the router, you will have to ask Airtel to turn on bridge mode at their end as well.

@MZRecords, unfortunately, the option to configure what I need doesn't appear to be available on my Asus router when I set it to Static IP mode. Additionally, I tried using a XZ000-G3 v1 device, which does register itself after I change its serial number. However, even with this change, I couldn't get it to work with the Asus router either. It seems like there's a compatibility issue or a missing setting that I'm overlooking. Any advice or workaround suggestions would be greatly appreciated.

Did your setup with XZ000-G3 v1 work with your PC? @sk7411

@tr1k0N4 , I did try in pc by using VLAN tagging mode but it gives me a 651 PPPoE Error during dialup . Since i have static ip , i also tried setting up those but with no luck.

@tr1k0N4 I have been following your posts regarding the airtel fiber router unlock and bridge thing. I have a few doubts.
My current setup is this. I have an Nokia G-2425G-A router that is locked from airtel. I have put it lan 4 on bridge mode and have connected to my TP-Link archer AX1500 (ax10) and have managed to successfully get pppoe connected. This is possible after adding vlan as 100 under iptv section.
My airtel router and tp link both get different public ips. I also have ipv6 enabled in tplink, WAN is No-Address and LAN is SLAAC + RDNSS.
Everything works, there is no double nat.

I also have a bsnl ftth router some Syrotech stuff that is my backup, earlier when the tp link was configured to be in dynamic ip, i could just switch the lan cable from airtel to bsnl and internet would be back.

But now with pppoe on my tplink, it will not be possible, until i discovered that there is an option of secondary connection with dynamic ip that can be added. and with my testing i figured out that even if pppoe is not successful, tp link will still use secondary connection for internet.

Now comes the annoying part, with vlan set to 100, bsnl router would not assign me an ip, nor would the airtel one on LAN1-3, turning off the vlan fixes this issue.
I tried calling airtel cc on 121 but they have no clue on bridge and ask me to talk to my LCO.

I want to know if unlocking this airtel router will allow me to connect to lan 4 in bridge mode without the vlan 100 tagging?

I think it should be possible since i will be able to edit wan and added a ipoe connection with vlan 100 on the airtel side of things, but i would still like your advice on this. Thanks and cheers.
