Verizon Q9c GPS Hack

[seeme]

I found out that Verizon has an authentication server that authenticates GPS requests to the network. Currently the only application that is allowed to make a request is VZ Navigator. So, no matter how hard you try to crack the phone it is the network that will restrict you since it will not authenticate the GPS application.

Why do you need authentication? It is needed to contact the PDE on the network and obtain the ephemeris data that the GPS receiver uses to determine which satellites to use to obtain a fix.

I know that the Q9c has the gps functionality from my useage of the phone as a developer on the unit. I also know that if the PDE does not give the information needed then it might not be able to get the satellite information. This is something that I am not completely sure about if there is no emphermis data if the Q9c will be able to obtain the information from scanning the satellites (non AGPS).

So the only thing is to keep asking Verizon to allow the applications to be authenticated. So everyone call your tech support and tell them to tell their manager that you want to have other applications allowed to access the GPS functionality or you will switch carriers (if that is what you intend to do).

A former developer worked on GPS functionality at a top Cell Phone Manufacturer.

That all makes perfect sense.

By the way, Field Force Manager is now available for the Q9c, thus being the 2nd application to use GPS on that phone.

It hasn't been a huge help to me (yet).

But this, in combination with this:
http://wiki.xda-developers.com/index...VerizonAGPSFix

May do us some good.

I connected to my phone with qpst but I wasn't able to write any data back to it. GPSTest doesn't recognize my device, (although it does hang on COM1 and COM4) and google maps simply says searching for satellites.

*shrug* I got a GPS icon at the top of my screen, somewhere along the line. im not sure how. one of those ## menus I think, or maybe a registry edit. but I dont think it's doing much.

The GPS chip *can* work unassisted. I believe thats how sprint configured theirs when they shipped. But I could be wrong.

Look promising. If the encryption is the same on the XV6800 and the q9c we should be in business. Or atleast closer.


I'll try it in a half hour or so.

I tried this with my Q9c and Google Maps would freeze if I tried to connect to COM2 or COM4. COM3 refused to work. COM1 brought up a Bluetooth error and would not connect.

Yeah, If I had to guess, I'd say they're using something similar to what they're using on the xv6800, so it'd going to need an adapter program (or a reflash of the GPS chip)

I suppose people have pulled the GPS intermediate driver out of the sprint phone and stuck it on the verizon phone just to make sure it won't work, right?

Can someone get me a full dump of the filesystem of a q9c with working GPS? How about a full dump of the registry?

We need to get firmware from sprint's GPSone chip, burn it to our GpsOne chips and then use Sprint's driver.

Or ...yknow....write an adapter program and driver like the guy from XDA-Developers did. but I wouldnt know where to start there.

this has been asked before in one of the other threads about verizon gps (or might have even been this thread)
check those out perhaps someone did it

I have called Verizon and complained a bunch of times. I suggest that everyone else do so as well. How do they expect to compete with the iPhone when they are charging extra for location services on phones that have GPS built in?

Question:

Has anyone who have signed up for VZNavigator been able to use 3rd party programs like Google Maps? Theortically if GPS needs to authenticate, once you sign up for VZN, the other apps should work.

This can be a class action lawsuit. I bought this phone almost soley for the GPS technology, knowing that it works on other networks like sprint with no issues. Their advertising and sales associates are misleading in the way they sell the phone claiming it has full GPS technology. I worked for a class action law suit firm and will take it to them to see if it is a possible case. Lets get Verizon to give us what we paid for!
