Following these steps may damage your router, void your warranty and even be illegal, please attempt it at your own risk, I take no responsibility for ANYTHING bad that may happen due to following this guide.

Prerequisites:

* a Serial-Ethernet adapter (I got one with my mweb router)
* A serial port on your pc (go figure)
* A terminal emulator (I use minicom under linux, Windoze users can try hyperterminal)

Procedure:

* Connect the serial adapter to your pc and plug an ethernet cable from there to port 4 on the Billion.
* open your terminal emulator and set it to 9600 8n1, no flow control. Repower the Billion and you should see text scrolling past and eventually get to a login prompt.
* Login with username: admin, password: admin.
* type this: pppoe clear transports
* press enter.
* open your favourite web browser and go to http://192.168.1.254/configuration/wan_rfc1483_bridged.html (that's 192.168.1.254/configuration/wan_rfc1483_bridged.html in full)
* change the vpi to 8, vci to 35 and click apply.

You can now dial a pppoe connection from your pc through the router and the default mweb account is gone. WooHoo!

I've messed with my billion 7401 considerably, and somehow got it to a state where it resets to factory defaults on each reboot, so I can't verify whether this will continue to work if you save configuration and restart the modem.

You may also be able to get to the cli with telnet by dafault, bypassing the need for the serial adapter, but I haven't tested whether that works.

I have just about given up on getting this router to accept the default unlocked billion firmware and have tried various different techniques, if anyone's working on it pm me, i might have useful info to share, even if it's simply what doesn't work.

You see now, companies try and put you in their black box but then friends help you out... Nice post..
 
I hope this can work with my Billion W40.
EDIT: Didn't work with my W40. Windows users should use PuTTY for telnet.

Unlock 7401 VGP

Hi there

Have you found a way to completely unlock the router? I can do it in part but I still get the @dsl dropdown menu so cant login to another ISP.

Please help

Thanks

Thanks for the guide, worked 100% :)

How would I go about changing it back non bridged mode?

Has anyone done this in the Durban area?

I am wanting to do this with my Billion from Nashua but I do not have a Serial-Ethernet adapter

Hi,
My PC doesn't have a serial port.
Any chance to flash it in another way?
Thx.
 
Hey will this work with a USB-ethernet adapter?
 
Nashua Billion 5200G R4 in bridge mode

I managed to get my Nashua locked Billion 5200G router working in bridged mode.

Here is what I did:
1. I log onto the router with my web browser (http://192.168.1.254/)
2. Go to Interface Setup, Internet
3. The Virtual Circuit PVC0 should be selected. Change it's Status from Activated to Deactivated and Save.
4. Change the Virtual Circuit to PVC1, set the Status to Activated, VPI =8, VCI=35, Encapsulation=1483 Bridged IP LLC. Do not change anything else. Do not touch the ISP PPPoE option.
5. Save and reboot to router.
6. Create a new broadband connection on your PC and dial it.

Hope it helps.
 
Just wondering if anyone has had any problems with flashing the 7401VGP?
Or once the steps are followed does it work perfectly?

Genius!
 
Matrix warehouse also selling a locked down router, reckon this will work for their router too?
My modem just screwed up and I have to find a replacement tomorrow before 2pm when everybody shuts till next week.
 
In theory it should work on any locked router, except if they locked you out of the virtual circuit options as well.
