DavidinCT's VZW xv6800 A-GPS guide

[Christopher Price]

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.

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.

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
