DavidinCT's VZW xv6800 A-GPS guide
 
Hey all,

As requested, this is my guide on getting a Verizon XV6800's A-GPS working. This is not of my own, this is from other posts around this site and XDA, this is just my method from all this to get it working. Most of the downloads are here and are not all mine. I assume you know your way around flashing and are pretty stong with Windows Mobile.

With this being said, if this guide helps you, please hit help below.

To start, if you have tried to get it working before and just had no luck, or just starting new follow this to start. From how I understand it, if you have a phone that has been updated to MR2, the PRL version will not work with GPS, so you will have issues. I suggest for everyone to do this (as it will fix this issue and solved my issues before)

1. Unlock phone, update radio, and flash custom rom (don't do anything to it, if you have already put on a custom rom, your already here)
2. Backup your data if needed or possable (PIMBackup is my fav for this)
3. After running a Custom rom, Roll back to stock(Older MR version) download everything from here (follow directions from this link)
http://forum.ppcgeeks.com/showthread.php?t=21161
(this will put the phone back on a old PRL).
4. Re-unlock, Re-update radio and reinstall your custom rom of your choice

Very clear, you MUST flash with a custom rom first, then back to stock, then back to your custom rom. Some people may disagree but, I know for a fact this works.

At this point you should be at a OLDER PRL version (AKA: MR1)

Now the fun part...

You need to follow these directions to setup A-GPS, Most of you who have been looking, has seen this but, I have copied the directions from the post but edited what needs to be relfected for your settings.

I set the settings I changed in BOLD (this will reflect the settings I used for Verizon.

We will:
Install a PC software package called QPST that allows us to edit a portion of our phone that contains gpsOne settings.
Install drivers on the PC to allow it to detect our phone running in diagnostic mode.
Put the phone in diagnostic mode, connect it to the computer, run QPST on PC, edit the gpsOne settings on the phone.
Edit the registry, soft reset, and test it out.

This is the orginal thread for above.

After you do a soft reset, you should be good to go, it's a little slow on the first lock (make sure your outside too).

This is the method I have used on 9 Replacement refub'd phones from VZW, and it has worked for me every time. The server settings are working as of 8/25/2010.

Does this work with MR2 as the secondary ROM?

Meaning, can I flash back to MR1, perform the changes, and then flash back to MR2?

I prefer stock ROMs, but will go the custom route if it lets me use GPS on the Titan. I still have one on Verizon because it's the most powerful phone you can use with the data block (yes, to this day).

As I understand it, as after I tried 6.5, I could never go back to 6.1... Even tried it for a day when I got replacement devices and I lasted a few hours before I flashed it. With this being said, I don't think you can run a OEM rom with these changes or a unlocked phone.

You would not be able to run MR2 with the GPS settings, MR2 does a PRL change on it, when it goes on, it breaks the GPS (the reason in the first step to flash rom then roll back to MR1). If you have MR2 installed and tried to get GPS working, you'll see why and you will have to install from the start of my guide.

My suggestion, find a small custom rom that someone made that will fit your needs (even if it's 6.1 there are some still out there that are very close to stock/MR2), then use this method to get your GPS working.

GPS + VZW MR2=bad

Just got it working. I did the *228 while on the stock ROM, then performed the upgrades and tweaks.

This continues to highlight how much of an opportunity Microsoft missed (in marketing, controlling carrier evilness, and last-mile issues like Marketplace). This was in the can before an original iPhone, and does more than an iPhone 3G.

Thanks for the compiled guide.

Uh oh, my A-Key got corrupted. Didn't do anything to the phone overnight, but this morning it wouldn't authenticate :(

Worse, the 6.5 ROM I had, didn't have EPST working right. Crashed on launch.

So, I'm now repeating the guide from scratch and flashing to DCD 3.2.6, then calling into Verizon to have the A-Key reset.

Anyone know of a 6.5 ROM that has EPST working properly?

Update: Ultimately went with RyanMogul's 6.5.3 ROM. Getting a 3D fix in about 30 seconds.

Not sure if the gpsOne server is being polled, since I have the data block, but I suspect Verizon opened up the Alltel IP address even on the data block. That, or the gpsOne silicon can get a faster 3D lock with autonomous mode and tower data alone...

... My connections are much faster when the phone radio is powered up than when powered down.

In all, this keeps impressing me about gpsOne as a well-thought out technology that was needlessly locked down by Verizon. Look at all the GPS apps on iPhone, look at what could have been had Microsoft mandated open GPS from day one.

Re: DavidinCT's VZW xv6800 A-GPS guide
 
One issue to report after testing this quite a bit. It's only of note if you use the Data Block on Verizon.

I think I figured out why VZW never unlocked GPS on these devices. The latest generation of data block is designed to allow you to connect to free data services (VZ Nav, Family Locator, etc), but basically return no data to any other IP request.

That screws up the A-GPS session, because the XV6800 (and SMT5800, etc) are told they have an internet connection... they then ping the LBS server... and get no response. The radio firmware doesn't know how to handle a blank/failed response, and the GPS times out.

The only solution is to power off the phone radio when doing GPS navigation or other GPS apps.

Yes, that makes it hard to use it on road trips, but I'm still happy. I have an Android phone on Sprint Relay Data Only, so I only need GPS on my voice phone for emergencies. This spares me the need to carry around a backup GPS device.

Re: DavidinCT's VZW xv6800 A-GPS guide
 
A tip, if you have problems with your A-Key, log into VZW's site, change your ESN to a old phone, then put in your current phone, this will update the A-key with out needing to talk to anyone.

Got this right from a vzw tech
