GPS Fixes by Carrier
 

Okay, I've just spent about an hour digging around the various "GPS not working" threads and came to one conclusion: I'm confused.

I believe there is a solid fix for Sprint users with the PPST.exe, and I think I saw one geared to Alltel users.

However, in each thread, there is a healthy dose of "don't do that" and "won't work for my carrier" to the extent that I was unsure what would kill what.

Does anyone know a solid fix, by carrier that could be consolidated for easy reference? I'm just saying is all...

If you want to send me a PM with your carrier and the steps you took to make it work, I will put them in this post for easy reference.

Good idea for a thread. I wish I had the info to put it all together but I'm still learning myself.

i need to know what to do for verizon...cuz after i flashed using the kitchen..i can never get a gps lock...not even once!

Re: GPS Fixes by Carrier
 

for my phone, I started with nothing, but then I installed Google Maps and after doing a connect twice to GPS, It started to 'work' by which I mean I had no sats, but it was processing.

One hard reset later, I was up and running, use google to 'prime' the GPS when I needed it.

Now I find I'm in that boat with others. When the unit goes to standby, the GPS never recovers, just staying fixed on it's last known location.

I've tried to remove the battery and re-insert, and that appears to get the GPS going again without a hard reset, but it's still not my fav.

check the sprint gps rom still problems stickied thread. i believe we found a fix for all carriers. Im on Telus, I used to get 4 sats in like 15 minutes, now i get like 8 or 9 in 30 seconds

verizon doesnt have a ppst.exe file....at least i cant find it..im building using the kitchen...

Re: GPS Fixes by Carrier
 

While I am a 6800 user on VZW I am very interested in the GPS issue too. VZW does have a PPST file but we would need to go back to our stock ROM, since the PPST is in extrom and most of us delete the contents first time we get a chance to.

I am going to read up and flash back. Once I have new info I will reply again here. I do have the SAT issue, where getting a SAT is now taking upwards of 10 mns to sync.

Being we are non Sprint User the Assistance Server will never accept Requiest from Outer Network so we must have to put the GPS into Autonomous Mode (Self Fixing)

I am using this Setting in SULP (Secure User Plane Client With Extended Ephemeris)

GPSMode = 1 means Autonomous (Self Fix no Assistance Required, Pessimistic Approach, Very Slow but Very Accurate)
GPSMode = 2 means Assisted by Server (Less Optimistic, Somewhat Slow but Medium Accuracy Quality)
GPSMode = 4 means Assisted by Server with Extended Ephemeris (Very Optimistic, But Sometime we loose Accuracy Quality)

EnableAGPS = 1 Means Enabled AGPS and 0 Disables it

EnableGPSSmartMode = 1 Save Downloaded Ephemeris Data and also Send it Assitance Server to Update / Fine Tune Extended Ephemeris Data on Server (Require Internet Connection), 0 Zero Desables this Feature

Ephemeris Data = To get Self Fix the Device must know the Position of Satelite in sky, which is called as Ephemeris Data, This is Combined Database which have there Altitude, Latitude, Longitude so the Phone , GPS Device don't have to wait to get Satellites Position from Frequent Satellite Self Position Broadcast by Air

Do you use anything to prime the GPS? I use Quick GPS, which downloads the SAT location info from the Internet to my 6800, and should help speed locks up...but I say should because it does not always work. I was in a cab in NYC on Thursday, and the cab had a SAT lock but I didnt for over 15 mins. Was very frustrating.

I am actually going to change the setting of Smartmode to 1 since I have an unlimited data plan...yea! Next you talk about a SULP client. Where can we obtain this?

Any assistance from you would be ideal. I love to learn.

Okay...tried the mode 1, and that blew. I didn't get a damn thing after that. so, here's what my adventure has taken me on today (again, this is a VERIZON 6900):

* Installed Quick GPS - didn't help that I could tell. The whole "isn't accessed, needs a middle man" argument seems to make sense
* Installed GPS Viewer - I let it run forever and although it kept seeing some sats, it bounced all over and never locked
* Put gps mode to 4
* Ran GPS Viewer again and this time got a lock in about 10 minutes. Not speedy at all, and really only hit about 5 sats (after removing battery for 10 seconds)
* Hit the forums again trying to figure this mystery out

The point I'm at, and again, this must just be becuase it's VZW:
* PPST isn't in my device. Even if I found a cab or something of the sort, I suspect running it would cause my unit to implode
* PRI version seems to be big for the Sprint devices..they have 2.something and mine is 1.37. Honestly, I'm not even sure what the PRI is (the shame...), but I know for sprint folks, it was updated via customization in the sprint 3.02 rom, which non-sprint folk are told NEVER LET RUN - YOU WILL BRICK PHONE and the such...
* I have seen suggestions to allow customizations to run in the sprint rom and then flash the rom of your choice, etc...

I've searched these forums 7 ways from sunday and see so many differing opinions, and largely they seem to apply to Sprint (and a few Alltel folks). But even if I assume the instruction is to let the sprint rom run all the way, I'm pretty sure you can't do that on a VZW phone..and just how would I go back anyway?
