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...

----------------------------------

Updated 6/1

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.

Re: GPS Fixes by Carrier
 

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

Re: GPS Fixes by Carrier
 

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.

Re: GPS Fixes by Carrier
 

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

Re: GPS Fixes by Carrier
 

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.

Re: GPS Fixes by Carrier
 

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

Re: GPS Fixes by Carrier
 

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.

Re: GPS Fixes by Carrier
 

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?

Re: GPS Fixes by Carrier
 

Ok here is my take on all of this...

I flashed the Sprint "leaked" ROM last night and let the customizations run. So this morning I had a yellow looking phone. I immediately flashed my VZW 5067 kitchen ROM and my phone came up with a solid roaming indicator and instead of saying Verizon Wireless it said Preferred System. After reading the threads I am getting this because I let the customizations run, which updated the PRI. My PRI is listed at 2.03_003 right now and the only way to get back to a VZW phone is to back it down to 1.37, which I guess is the VZW supported PRI.

I do have to say while on the 2.03_003 PRI, and incorporating the GPS that HetaldP mentioned, I was able to get a SAT lock in seconds. I do enable SmartGPSMode since I have an unlimited data plan, and that obviously helps. I plan on backing down my PRI asap and then will re-test GPS.

So based on my experience I would not let customizations run. While the PRI does get updated it screws your phone up. VZW needs to address this asap, and I guess we will have to wait until they bring out a stock ROM.

Re: GPS Fixes by Carrier
 

I have my Bell Mobility Touch flashed with the PPST, and I also have my PRI updated to the Sprint one, just by installing the PPST cab, and running it. I now am able to get a lock much faster than before, and I can confirm this. Before I would have to sometimes wait even up to 3 minutes, and rarely it locked within 30 seconds. Now it locks in after 25-30 seconds all the time, regardless of the phone entering sleep mode or even after a cold boot it takes about the same time. I also set my gpsmode to 4, and I have smartGPS enabled as well. Good luck, and remember you don't have to flash to a clean firmware after doing this, simply just updating the PRI will do. It will not screw up your Bell Mobility Touch at all in any way, I don't get any IOTA errors either.

Re: GPS Fixes by Carrier
 

Any Verzion users have luck installing the PPST cab on the Verizon phone? Or the Sprint PRI on the VZW phone? The previous poster indicates that doesn't work for VZW, and most other comments I have seen say it's bad karma to mix PRI versions and carriers.

Re: GPS Fixes by Carrier
 

Are you sure it's safe to run PPST on a Bell touch? I ran PPST when it was first discovered without thinking what it would do to my phone. At first, GPS locks were fast and within less that 1-2 min. But I started to run into problems with getting slow or no internet connection at all. I did a hard reset and got internet back, I checked my PRI after and it's 1.3 something. So I guess everything went back to normal, now GPS would lock in 5-10 min.

Re: GPS Fixes by Carrier
 

yeah check the sprint gps issue sticky. There are details on how to enable the gps portion of the sprint pri and have your carrier PRI as well

Re: GPS Fixes by Carrier
 

Where in the thread? Can we get a post number

Re: GPS Fixes by Carrier
 

Here you go:

Re: GPS Fixes by Carrier
 

Yes, I would like to see that as well. The GPS information is spread out all over, and most of what I see doesn't even ID the carrier. Or in some cases, ID's another carriers (typically
Bell or Alltel).

And when I see recommendations like "install the PPST cab" or "let customizations run" and then elsewhere (such as in most all the instructions) is says "don't let the customizations run" and "now my phone is stuck in roaming", I think maybe wires are getting crossed.

Seperate Topic - But Related
 

All,

As you can see we have lots of information all over the place, and its not getting any better. I have made a request to the powers at PPCGEEKS to open a forum dedicated to GPS/SAT information, and NAV software also. I have big ideas for this forum, but to date have not gotten it created.

Should you agree its time to do this please go to the Forum Request section and post a reply to my initial request that you are in favor of this. Its only when we all speak up will things move in our favor.

Thanks,
Steve

I totally agree. http://forum.ppcgeeks.com/showthread.php?t=27130

Re: GPS Fixes by Carrier
 

This says it's safe for Telus users. I tried, just for fun, dialing *22803 from my VZW phone and it goes to US Cellular. I think this might be another case of a fix being specific to a carrier.

Re: GPS Fixes by Carrier
 

The order can be 1,2,3,6,4,5. That might work better jack. Try it out, let me know. That 22803 might need to be 228 for you, but im not sure.

Re: GPS Fixes by Carrier
 

OK - 22 Pages + of reading and scanning and eyes watering and all I see is Sprint users are stoked ... all others can just hang.

Is there a fix in there for us non sprint users ghettofreeryder?

Need a sprint PRI and a ppst.exe or some such business ... that might as wel been in ancient Mayan because - yo no comprendo.

Re: GPS Fixes by Carrier
 

I did alot of testing early this am (yes 2 am) with my 6800, and following the directions here. So the steps I took were as follows:

1) Flashed leaked Sprint ROM - did not run customizations.
2) Installed and ran Sprint PPST - installed without issue. Checked and was running 2.03 PRI.
3) Obtained MSL for device
4) ##778# completed successfully.
5) Tried *228 for Sprint but got automated msg to enter Sprint number.
6) Flashed 5067 ROM to device successfully.

My 6800 booted up and I was able to *22899 for VZW successfully. This allowed the voice to work fine. The data at this point was dead with a PPP error 11, which is an auth error. Left it for the morning and called VZW tech support, who got me a new A-Key.

At this point I dont know if this will work for us VZW users. I have not seen a VZW success story with this updated PRI. I am perfectly willing to continue working on this, but not sure where to head. Would like some help!

Re: GPS Fixes by Carrier
 

Verizon info ...

So I have a 1.x PRI - whatever it does or is ...

I have already :

1. Unlocked my stock Vzw touch with coke 2.31x

2. Flashed the Alltel Rom which had a 3.35 radio - then I read on OMJ's post
no customizations were allowed to run on above Alltel FLASH

3. Flashed the leaked Sprint ROM which took the radio to 3.37 - as per OMJ's ROM upgrade thread.

4. Did NOT let the Sprint customizations run ...

5. Flashed OMJ's Full Custom verizon version rom with GPS / Rev A and WM 6.1.

6. Called Verizon support and got a new "akey" ? - i think - they reset something - I send/rec'v calls now.

I have never made anything near a conection with a GPS Sat

My Internet speeds a < 500Kbps [2000 kbps was why I wanted to flash :disgust: ]

Re: GPS Fixes by Carrier
 

Yah, I'm still on the fence about the PRI. I've seen enough people say it didn't work to believe it doesn't work for VZW, but again...nothing is to organized. Anyyy wayyy...

So, I unlocked the phone using 2.31, flashed the sprint 3.02 rom (without customizations), then did the Vogue 3.02 GPS from the kitchen. My experience has been very good overall -

Rev A is for sure there, no changes needed. tests have been between 500k and 1035k, so that's definitely kicking.

After all my mucking with the GPS, it does work, but the rules are pretty strict. I have to use GPS Viewer to start it up...and that can take up to 5-10 minutes to lock. Sometimes it's a little quick and I'm usually about 7 or 8 sats outside and 3-5 inside by a window. However, if it goes to sleep while the GPS is active, it won't come back unless I remove the battery. So I must close all GPS apps and then close the GPS in GPS Viewer. If I follow those instructions every time, once it's tracking, it's reliable outside and decent by a window.

So given the fact that I can make it work through careful planning, I'm not in a big hurry to try to go backwards (which I suppose is another topic..I'm nervous, having already flashed the radio up to 3.xx, to try to go back to the stock VZW rom to then do the sprint rom to then do the kitchen again..but I digress slightly) just to maybe get a faster seek time and then end up with no data, or no radio or always roaming or any of the other horror stories I heard.

Re: GPS Fixes by Carrier
 

Based on wha I have seen and experienced I am going to wait to see more VZW successes or wait for the VZW official upgrade. They have got to have something in the pipeline since they are the last carrier now!

Re: GPS Fixes by Carrier
 

Not going to believe this !!!! But .... I stumbled UPOn this post and lo and behold - checked my settings and - wanted to do evil things to this phone!!! was set to 911 ...

Got some Sat hits - gps viewer NEVER indicated a position fix or from what i could tell were legit LOCKS but I saw 5-6 different sats I think. Wil continue to test.

Re: GPS Fixes by Carrier
 

How did the PRI update go?

Re: GPS Fixes by Carrier
 

THIS POST PERTAINS TO VERIZON XV6900 ...

Which phase bro ... :mrgreen: I ve been on this thing all damn day!

I have the 1.3x_xx PRI now - but as I stated in another post I jacked up your sequence instructions. So Im not sure exactly where its at - other than I can now make calls - access the internet and got a blue dot on google maps :-)

That said ... I Did steps 1 & 2 that you posted on the Sprint Leaked ROM. Then before step 3 I did flashed to the OMJ Custom Verizon ROM - then performed steps 3, 4. Phone didnt really work at that point. I had to place a call to vzw tech support [2nd time today] to make calls, check vm & get net access.

Vzw tech support gave me a 26 digit A-Key to install - walked me thru that install. Then checked my web user name and password access settings, then did some network reset on their end, then all was connected and functioning. Then I found that post about the Location vs. 911 only settings - then satalites came into my life.

Re: GPS Fixes by Carrier
 

well, I posted some files so you wont have to flash again, which is I think what went wrong. I believe you let the customizations run. I posted the PPST and the EPST, so it should be easier now, if you wanna try.

Re: GPS Fixes by Carrier
 

I did not let the sprint roms customizations run, but did let the OMJ Verizon customizations run ... ??? Bad?

I want to try - but man - I do not want to call sprint again! LOL ...

Re: GPS Fixes by Carrier
 

you mean call verizon? If you dont wanna try, I wouldnt bother. Thanks for trying though

Re: GPS Fixes by Carrier
 

I followed your directions on my Titan and was able to get GPS lock from within my bedroom quickly. The problem is I could not make/receive voice calls. Doing *228 failed both times so while it gets the data pumped up the voice is dead.

Re: GPS Fixes by Carrier
 

is the PRI issue only about the a-key? didn't i see titan instructions about copying info like that out of the phone before starting? does that apply here?

Re: GPS Fixes by Carrier
 

It might!

Re: GPS Fixes by Carrier
 

Pretty much a known issue with the 6900 devices on Verizon network. Reflashes and hard resets require new a-key and/or the tier 2 tech support person at Vzw to reset their network to allow your device user name / password.

I needed a new A-key and to reset the data auth user/pwd on the phone and the tech had to refresh something or change somehting on their network. The network wasnt allowing me to authorize and get on the network.

Just one man's experiences - 2x in one day :-)

Re: GPS Fixes by Carrier
 

i had to do this twice already...but since using the kitchen..after flashing ihavent had to call verizon..

just wish i could get the gps to work...that was the whole reason for me flashing..

Re: GPS Fixes by Carrier
 

Run the PPST from Sprint. See the sticky at the top of the forum, the one that says Sprint GPS in the title. We have found a way to get the PPST from Sprint onto the Bell, Telus phones, and maybe verizon

Re: GPS Fixes by Carrier
 

And this is the whole reason I started this. I've seen people say that the PPST doesn't work. Any Verzion user confirm the functionality of installing the PPST from sprint as a fix without mucking up the phone or destroying your A-Key?
