*nix server with Squid (optional)

Unlocking WAP

To unlock the WAP functions you need to edit one file and a proxy server. The server could be yours or a public proxy. It doesn’t matter much.
Here are the steps:
Configuring your phone and laptop to talk via Bluetooth:

Open Bluetooth Setup Assistant ( From the Bluetooth, choose Set up Bluetooth Device)
Click Continue, choose Mobile Phone without clicking Continue
Go to Menu-> Settings & Tools -> Bluetooth Menu on you phone and choose Options with the right button. Select Discovery Mode and say Yes to the question Turn Bluetooth power on, if it asks, and change the mode to On.
Now click Continue on your Bluetooth Setup Assistant. Wait a few seconds for the phone to show up.
When the phone is found it will show up as LG VX8550. Select it and click Continue
Look at your phone again. It will ask you “Pairing request from Compter. Accept?” Select Yes.>the_name_of_your_computer>
Now click Continue in Bluetooth Setup Assistant and you will see an authorization number.
At the same time, your phone will ask you for the same number. Enter it and click ОК. If everything went well, the phone will say “Paired successfully”. Hold a few seconds and select “Always Connect” when asked “Before connecting”.
Look again at Bluetooth Setup Assistant. Select “Use with Address Book”, “Access the Internet with your phone’s data connection” and “Dial a specific number for your Internet Service Provider”. Continue.
Fill in the fields as follows:
- Username: your phone number + @vzw3g.com. If your number is 212-221-1221, then the Username will be 2122211221@vzw3g.com.
- Password: vzw
- Phone Number: #777
- Modem Script: Verizon Support (PC 5220)
- Select only Show Bluetooth status in the menu bar and Show Modem status in the menu bar
Click Continue and then Quit

Unlocking with BitPim:

Run the latest version of BitPim.
Go to BitPim->Preferences.
For Phone Type select LG VX8550
For Com port enter /dev/cu.LGVX8550-BTDIAG-1 and click OK
From the View menu click on View Filesystem
Now click on File System in the left panel and go to directory OWS
With the right button click on the file paramtable1.fil and choose Save. Save the file somewhere. Save it one more time somewhere else for backup
Start 0xED and open one of the two paramtable1.fil
At the start of the file you should see: 30 1E 00 01 . Change the third pair to 20, to end up with 30 1E 20 01.
Save and close the file.
In BitPim again right click on the file paramtable1.fil and select “Overwrite”
Navigate to the file you just edited, select it and click on Open
When the light on the bottom left corner is green, right click below the files and select Reboot Phone.
When the phone is on again dial:##77647268550 which comes from ##program8550 and press Send. The password is 000000.
From the menu go to Wap Settings->Proxy Address Setting
Now you must enter your proxy.
Change the port of the proxy from Wap Settings->Proxy Port Setting
You can change the Username and Password if your proxy requires it.
I advise you to change your Home Page to http://www.humpa.com/homepage

At this stage you should be able to setup a shortcut News & Info and to use it to go to http://www.humpa.com/homepage

Setting up the phone as a modem

If you have not done so, please go through the steps in “Configuring your phone and laptop to talk via Bluetooth”. After that all you need to do is:
Disable unsupported authorizations:

Open Termina.app
type: sudo pico /etc/ppp/options hit Enter and enter your password
type in the following three lines :
refuse-chap
refuse-mschap
refuse-mschap-v2
Press ctrl+o and hit Enter, then ctrl+x and close Terminal.app

Now go to the program menu by dialing :##77647268550 which is ##program8550 and click Send.The password is 000000. From the menu Network Select->Mode Preference select 1X Only. Press ОК and you are ready to use your phone as a modem anywhere you have signal at the price of a phone call. To connect, go the the phone icon on your menu and select Connect. If everything went well, you should be online in a few seconds.

Unlocking EVDO

Without EVDO both your WAP and your phone will be limited to about 17KB/s. To unlock the power of the 3G network follow the steps in “Configuring your phone and laptop to talk via Bluetooth” and do the folowing:

Run the latest version of BitPim.
Go to BitPim->Preferences.
For Phone Type select LG VX8550
For Com port enter /dev/cu.LGVX8550-BTDIAG-1 and click OK
From the View menu click on View Filesystem
Now click on File System in the left panel and go to directory /nvm/nvm
With the right button click on the file nvm_data and choose Save. Save the file somewhere. Save it one more time somewhere else for backup
Start 0xED and open one of the two nvm_data
At the bottom of the file you will see XXXXXXXXXX@dun.vzw3g.com on two places, with XXXXXXXXXX being your phone number. Now you have to change the dun.vzw3g.com part to vzw3g.com. It is very important not to delete anything, but just overwrite and add 00. If you select dun.vzw3g.com you will see on the left that you’ve selected: 64756E2E767A7733672E636F6D. In order to not change the size of the file change these with:767A7733672E636F6D00000000. On the right you should see how one of the dun.vzw3g.com is now vzw3g.com. Repeat with the second dun.vzw3g.com
Save and close the file.
In BitPim again right click on the file nvm_data ( in /nvm/nvm ) and select “Overwrite”
Navigate to the file you just edited, select it and click on Open
When the light on the bottom left corner is green, right click below the files and select Reboot Phone.
When the phone is on again dial:##77647268550 which comes from ##program8550 and press Send. The password is 000000.
From the menu go to Network Select->Mode Preference
Then select Digital Only Hybrid and click OK

If you see ЕV and 1x in the signal strength field of your phone, than you have EVDO in your area. Now when you connect to the internet, through the modem or through WAP, you will use speed of up to 70KB/s

Please be careful what traffic you generate.Both volume and type.

More soon…

do these changes work the same on a chocolate phone from telus?

Comment by Seth — 2007-08-07 #
I do not know. You can try. Just backup your files before editing, and if something gets messed up you should be able to restore them.

Comment by TeraHz — 2007-08-08 #
In the unlocking EVDO section do you mean nvm_data when you write ‘In BitPim again right click on the file paramtable1.fil and select “Overwrite” ‘?

Comment by Gabe — 2007-08-11 #
Yes. That was supposed to be nvm_data not paramtable2.fil… I fixed the post.

What’s the program phone number to use if you’re in the US?

Comment by Fast Eddie — 2007-09-02 #
hello, i cant seem to connect bitpim to my lx vx8550 using bluetooth. I have a macbook, any help?

Comment by Mike — 2007-09-10 #
Един въпрос ? Може ли всичко това да се направи на телефон NOKIA 6230i ?
Благодаря предварително !

Comment by Милко — 2007-09-17 #
@ Fast Eddie
If you are asking about the login number it is your own number

@Mike
Can you be more specific? I’ve done the above steps on a macbook several times.

@Милко
провери howardforums.com Ако може там ще го пише.

имам Ел Джи вх9900 мога ли да ползвам негови функции и кои

Comment by rumes — 2007-12-28 #
Thank you. This works great, though with Bitpim 1.0.3 I had to use VMware fusion/WinXP to get Bitpim recognizing my phone. The /nvm/nvm folder kept resetting under OSX 10.5, plus a few other major UI issues.

Thanks again!

Nice information LG Chocolate. Just got one. I am trying to unlock WAP via BITPIM.

Have performed all except when I get to this we you write:

From the menu go to Wap Settings->Proxy Address Setting
Now you must enter your proxy.
What proxy should I use?

Change the port of the proxy from Wap Settings->Proxy Port Setting
What port of the proxy should I use?

You can change the Username and Password if your proxy requires it.
How will I know if I have to change username and password?

This may be dumb but how do set-up a shortcut for News & Info and to use it to go to http://www.humpa.com/homepage?

Thanks in advance for any help you can provide to me.

The proxy server must be an open proxy. You can find plenty on the internet. I have not posted one, because they tend to go down pretty often, but using google you can find plenty of open proxy servers. Usually they will say if they need an username or password.

I am running my own proxy server just for myself, that relays all traffic through my machine.

When you press the up arrow it will open the browser. To set that page, you need to change your homepage from the service menu -> Wap Settings -> Home Page. Once you change that, your phone will reboot and when you click “up” on the wheel it will open the browser and try to load whatever page you entered.

You can also find an already hacked paramtable1.fil that has everything you need, just look for it on howardforums.com

Goog Luck

Thanks will try some of the things you said.

One question about find an open proxy service…security?
Any advice?

Thanks again, C. Logan

Comment by Cornelius Logan — 2008-02-03 #
Well that is always a problem, that is why it is best to use your own proxy.

You might try to use an anonymous proxy that will help somewhat with security, but they tend to go down faster than regular proxies. Good thing you can add Primary and Secondary proxy servers in your WAP settings.

Comment by TeraHz — 2008-02-03 #
Again thanks. Just for your info, besides your very informative blog for unlocking wap on the VX8559, I have also been you this tutorial: http://www.se7ensins.com/forums/cell-phones/41454-free-wap-chocolate.html

Next I will try unlocking EVDO from your info!
Have a good day or night where ever you are…THX!

May be a dumb question but what is termina.app? I am running windows XP and am using BitPim to communicate. If it is software, where do it get it from?

Comment by Colton — 2008-03-06 #
It is a terminal emulator application for Mac OS X. The above instructions are for Mac OS X, but for the most part they should be either the same as on Windows, or give you an idea of what to do under windows.

Comment by TeraHz — 2008-03-06 #
How can I use this, I am lost with this, does this help with bluetooth file transfer “unsupported” notifications as well or is there another way to do that?

Comment by Colton — 2008-03-06 #
I’m sorry, but I do not know what are you trying to do and I do. As I said, if you are looking for a step by step guide for windows you need to look elsewhere.

Comment by TeraHz — 2008-03-06 #
No, I was asking if there is a way to unlock the multimedia transfer through bluetooth (transfer videos to friends phones). Is there anyway to unlock this feature instead of getting the “Unsupported” notifications? Thanks for being patient with me.

Comment by Colton — 2008-03-06 #
I don’t think so. But if you find out how to do it, please let me know. So far the only way to do it using BT is transfer from my phone to my computer and then send to the other phone.

Comment by TeraHz — 2008-03-06 #
Ok cool, Thanks for helping me out, Good stuff here!

Comment by Colton — 2008-03-06 #
Just wondering, what exactly does this do? Does it allow you to use the internet free on the phone?

Comment by Perez — 2008-04-14 #
Is this for the American verizon chocolate only. Or does this work for all types?

Comment by Kyle H — 2008-06-30 #
The above is working on the american chocolate and I don’t know if any of it will work on other chocolate phones.

Comment by TeraHz — 2008-06-30 #
Hello, I really enjoyed your tutorial. I can connect to the net with just my phone without any problems. I had a question pertaining to the “free” modem method. I am running vista and even after setting up a proxy and such I am still asked to pay money to connect to the net, when I use my phone as a modem. I was wondering if there was a way to do the mac trick i.e. “Setting up the phone as a modem” on a windows machine? I also tried the “Unlocking EVDO” trick and I could not connect to the net on my phone alone.

Comment by billtodd — 2008-07-24 #
What proxy software are you using? I’ve tried kannel with no luck.. is there some kind of trick with this thing? It needs to be a wap proxy correct?

Comment by wailer6084 — 2008-09-06 #
I use squid. It has to be a proxy, that is all. No specific type. If you manage to configure it so that you can go to the Internet through it, then your phone should be able to as well

"The spirit of emptiness is immortal.
It is called the Great Mother
because it gives birth to Heaven and Earth.

It is like a vapor,
barely seen but always present.
Use it effortlessly." - Lao Tzu (老子)
