[Mogul, XV6800 ROM Development] shadow-tech:
thanks for the try. i think i have figured this out already though. if u wait a like 4 hours (maybe more) then load up google maps. let it do what it needs to do till the loading words are gone. then disable ur data connection. then click 'use gps'. u WILL see that it will initiate a data connection before u see anything on the map move/change.

This proves that the phone is using the PDE serve which means that agps is working.

i little bit about gps is that there are exactly 24 satellites out there hovering around us. they are not geosynchronous. which means they move in and out of location. this is good. they are at an orbit that makes it so there are always 4 satellites at the minimum available. i think each satellite is available for around 30mins-2hours. so if there is 4 then it could be between 2hours and 8hrs for the agps info to be outdated.

if the agps data is not outdated then the gpsone chip will not try to update it. that means it will not attempt to make a data connection.

thanks for your efforts and feedback.

ill do some housekeeping on my posts tommrow

IS the party over???

Not getting any locks this AM. Is it my 6800 or is the party over???

Do The Changes Stay Persistent?

Morning all,

Yesterday was a glorious day for all of collectively now that GPS finally was working well!!

Last night I had to flash my phone to do a couple of upgrades, and this morning I tried out the GPS again. Alas it was back to not connecting for at least 10 minutes. So the question is....do the QPST stay persistent even with a flash? I believe they did with GC's first fix, but is this the case for this one too? Anyone run into the same situation I am running into?

I plan on looking to see the reg setup, and then the QPST setup. Maybe something got overwritten?

Steve
[Mogul, XV6800 ROM Development] nitro66215:
I have the same issue. Try pulling the battery from the phone. Let it sit for 5 to 10 minutes. Then put it back in... and try again.
[Mogul, XV6800 ROM Development] pjsockett:
Took me a while to locks this morning too. Still better than before the fix but I was about 2-3 minutes rather than 5-7 seconds.
[Mogul, XV6800 ROM Development] legacydevice:
For what it's worth... I'm not getting a lock for **** this morning; yesterday after the fix I had instant locks all night!

Uh oh... :(
[Mogul, XV6800 ROM Development] nitro66215:
Same here. Try the "Pull the battery and wait" method I described above. Then go into QPST and reset the settings.
[Mogul, XV6800 ROM Development] Protonus:
I am also unable to get a lock this AM.... worked great all last night...

I went into Google Maps to try it out again this AM. When I hit "use gps" - after it initializes like normal, it then goes to "seeking" like usual. Like before, it instantly recognized a few sattelites, 3 in my case, and then said it was working, but the location was wrong. it was where I was last night. I closed google maps, soft reset, tried again, and it never got past seeking. Tried live search, it never was able to get a fix either....

Think they banned us? :-( I mean, if we're connecting to an IP - coudn't they just blacklist customers who don't have VZ Navigator?
[Mogul, XV6800 ROM Development] Zenoran:
Weird! My settings were gone this morning too! Not quite sure why that is... I was messing with trying to get the new PRI to update yesterday which never worked... stayed at the old one... but I'm pretty sure aGPS was working before I went to bed and this morning settings were gone.
[Mogul, XV6800 ROM Development] gbenj:
same problem for me too, was working flawlessly yesterday, never too more than 10-15 seconds...today, a couple of minutes, to finally get a lock, and much fewer sats...3-5 as opposed to 6-9.

just went into qpst and saw that ip and other settings were empty. i havent messed around with anything since yesterday.
[Mogul, XV6800 ROM Development] Zenoran:
anyone able to get a lock even after putting the settings back? I'm in my office (never used to get a lock here) and am not sure if aGPS should allow me to get a lock in here or not.
[Mogul, XV6800 ROM Development] nitro66215:
My phone looks like it's getting the aGPS data fine. I have 3 super strong signals in Gamin Mobile XT. But, it won't lock. Every now and again, I get a small hit that I believe is an actual satellite
[Mogul, XV6800 ROM Development] gc14:
How were you going about updating the PRI?

I've also updated the first post.
[Mogul, XV6800 ROM Development] gbenj:
i never updated the PRI, but the setting were still gone this morning. i put them back in, but dont know if its back to normal, I am getting locks, but not in a place i normally dont, and my number of sats is way down from before
[Mogul, XV6800 ROM Development] calash:
My settings are fine, but I saw a 10 minute lock this morning. I was messing with the registry settings and assumed it was due to that.

I will run some tests this weekend.
[Mogul, XV6800 ROM Development] nitro66215:
GC... I also notice that in FieldTrial ##Debug that under GPS everything says N/A. What's up with that?
[Mogul, XV6800 ROM Development] Zenoran:
I was attempting to update it with the Radiorefurbish.exe /Refurbish but it wasn't working... it messed up current ROM by putting triangle up in top bar so it did SOMETHING... I tried reflashing a ROM (as per the messages on the thread) but it still retained the old PRI... I just gave up on it and decided I'm going to stick with the old one seeing as everything was working so well... the aGPS was working fine after all that nonsense though I don't think it's related to this.
[Mogul, XV6800 ROM Development] nitro66215:
Use lower case /refurbish
[Mogul, XV6800 ROM Development] serfboreds:
Not sure if it is coincidence but it feels as if I am locking similar to before the fix (usually >1 min on hwy, not indoors, HTC GPS not scrolling like crazy off the bat like yesterday). Rechecked PDE settings and had to reenter.

Nothing could have removed settings overnight right? GC (or anyone else that can test) can you confirm that aGPS is still working for you? Let us know what ROM/Radio/PRI/etc you are running.

Running PRI 2.03_002.
[Mogul, XV6800 ROM Development] Zenoran:
err actually that is what I did...it obviously did something so I know it was trying to work but it just didn't update the PRI.. I'm yet to read someone who has successfully updated with that method.
[Mogul, XV6800 ROM Development] nitro66215:
That will just revert to what PRI is stored. To update it... used the signed_*** file that is in the ExtRom.

Edit: then run PPST.exe to "Update". This may screw up some settings. Just be aware.
[Mogul, XV6800 ROM Development] jimnutt:
And yet another with erased settings this morning. Wonder what's up?
[Mogul, XV6800 ROM Development] nitro66215:
Funny.

I unchecked everything in QPST GPSOne tab.

Set the IP to 0's.

Set the port to 0.

Changed the other two to DBM and Mobile... Exited. Soft-reset.

Pulled the battery and put it back in....

And still have the same affect as this morning. GPS Viewer just hops around.

I was expecting nothing. Just to test that these settings are taking.
[Mogul, XV6800 ROM Development] gc14:
Let me clarify this a bit more for you Zen.

Install the attached cab.

Navigate to \Windows and run PPST.exe. Proceed with the update. It will offline your radio during the update and soft reset after.

After the reset, navigate to \Windows again. Run WriteDMData.exe. Nothing will pop up, it will just run (again it will offline your radio). You'll know it's done because the File Explorer will refresh and bring you back to the top. Perform another soft reset.

That should update the PRI, though you'll have to reapply the agps fix as stated in my first post. You'll also have to turn Location On again, as the PRI update sets it back to 911 only.

Hope this makes it a little more clear for you and any others wanting to update their PRI without flashing MR1.

P.S. My aGPS is still working fine...
[Mogul, XV6800 ROM Development] jimnutt:
I got nothing this morning. No lock, no satellites. GPSToday got its last position fix 9/4/2008 at 19:35 EDT, haven't been able to get a lock since. It was taking about 30 seconds to lock (never did get the "instant" locks, but it was still a couple orders of magnitude faster), but now....

Done the battery thing and verified the settings in QPST, no go.
[Mogul, XV6800 ROM Development] nitro66215:
Before, I had a lock with this much strength. Now I have nothing.
[Mogul, XV6800 ROM Development] Zenoran:
thanks very much... haven't seen that process layed out anywhere and didn't mean to sidetrack the thread but that worked beautifully.
[Mogul, XV6800 ROM Development] legacydevice:
Well, just to clarify, since I did the fix yesterday, I haven't mucked around in the registry, haven't installed anything, and haven't changed PRI's. I list PRI 1.35_002 and am using radio 3.42.40... and I'd assume I'm in the same rough geographic location as GC. Weird. :confused:
[Mogul, XV6800 ROM Development] Protonus:
I checked my settings in QPST. They are the same as I set yesterday. The aGPS settings are all still there. I soft reset again, same issue. I cannot get a lock. I also haven't changed anything since yesterday when I did the aGPS hack.
[Mogul, XV6800 ROM Development] JustFine:
This was exactly what I experienced. Working last night. Not working this morning with QPST and registry settings the same as last night (and as in the wiki).

Just like last night when it worked, I'm showing data usage each time GPS is turned on, but never getting a fix.
[Mogul, XV6800 ROM Development] psternklar:
In GPS Test I notice I will see 7-10 satellites then 1 then none then basck to 7-10 but not getting a lock. I also see data when I try. GC any idea what is going on? Thanks.
[Mogul, XV6800 ROM Development] madsuse:
Same Issue Here

I am experiencing the same issue here. Did Verizon cook up a rotating port number or IP Address to throw us off?

By the way I had this working on the new PRI prior to today.

I originally upgraded to the MU1 update from Verizon and had no GPS.

To correct that I did the following.

1. did GC's new Fix

2. flashed bootloader 2.47

3. flashed to stock (yes with bootloader 2.47) and let customizations run

4. flashed dcd 3.2.6 via SD

5. flashed radio 3.42.50 via SD

I was getting 10 to 15 second locks after this until today.
[Mogul, XV6800 ROM Development] jambrose:
I noticed if I am short on memory (SPB Mobile Shell will kill my Titan but love the shell) the GPS seemed to run but not lock. I would do a soft reset and not run SPB MS and it would lock around 10 seconds inside where it wouldn't before.
[Mogul, XV6800 ROM Development] tbhall77:
Same issue. Wasn't getting locks the next day while testing Shadow-Tech's settings of "Mobile" in QPST and GPSMODE=2. I did look in QPST and my settings were still how I had them. I port scanned 66.174.95.132 on port 8888 and it is still open.

I used HTC GPS Tool to "clear memory" and I did a "nav. Init." I got a lock in 20sec.
[Mogul, XV6800 ROM Development] Zenoran:
so everyone is broke except gc? ;)

is it possible they locked down that server based on location or something?
[Mogul, XV6800 ROM Development] deboy_001:
Thanks for the try, but didn't work for me. :( I'm on 2.42.50 though and nueSPL. I guess I could try .40 and Olipro2.40 when I get the time tomorrow.
[Mogul, XV6800 ROM Development] legacydevice:
Well, I'm under the assumption that GC is in the greater Boston area, as am I... and my GPS is basically out of business today.
[Mogul, XV6800 ROM Development] jambrose:
No, his changes significantly reduced lock time for me and I now lock in my house where it didn't before. It sometimes still doesn't lock in doors but still locks outside with more satellites than before.
[Mogul, XV6800 ROM Development] joojoobee666:
Yep, add another to the list of not working today. I checked in QPST, all my settings are still there....

sucks....:mad: Maybe Verizon found this thread and is pissed that we were using their servers and not paying them....*shakes fist*
[Mogul, XV6800 ROM Development] Zenoran:
Obviously SOMETHING they did... Really really really frustrating seeing as we SAW that it's possible and were very happy with our phones for once. I'm really upset with verizon if infact they did lock this down because every other carrier offers this as basic functionality for using their service and they should as well. Obviously there is no network limitation not allowing them to provide this service/functionality because we all SAW it working.

Hope someone can shed some light on this and possibly get us back up and running again...
[Mogul, XV6800 ROM Development] tbhall77:
For those having trouble and still have their proper settings, try using HTC GPS Tool and do a "clear memory" and a "nav init"
[Mogul, XV6800 ROM Development] symyn:
I am back to the 2 minute lock, but unlike some of you my QPST settings had reverted back to default. I added the ip, etc, wrote to the phone, soft reset, and still no 10 second lock.
[Mogul, XV6800 ROM Development] joojoobee666:
Tried it, no difference. Even pulled the battery, back to the same BS...*sigh*
[Mogul, XV6800 ROM Development] Scott:
Its working again

I like the last few posters had the same issue. Thought it was the new Rom I made last night. I finished it up at around 3:00am Central time and couldn't get any locks. Went upstairs to the primary level and got locks in about 45 seconds which was about average for nonaGPS for me. I thought maybe because my battery was under 10% it wouldnt work? Drove to work and couldn't get a lock this AM either. I hard reset halfway there and it started working again. I thought maybe it was some new OEMS I put in, namely Advance Configuration from the PPCGeeks OEM repository.

So after hard reset it started working great again. Didn't look at QPST but I assume it couldn't have changed because I am getting locks again where I never could before. Its also VERY overcast and near raining. Normally I would just search forever in this weather but it caught in under 20 seconds using live search.

Maybe the server was undergoing maintenance? Would make sense because it went down early this AM and came back up four or five hours later.

EDIT: Just checked QPST and all my settings were the same. Nothing changed. I am sure it was maintenance.
[Mogul, XV6800 ROM Development] lllboredlll:
My lock times have been a minute or less today as compared to instant yesterday. Another thing to think about is server congestion. I'm sure there have been thousands of requests hitting that server since the IP was released. I did notice when I changed my gpsmode to 4 in the registry it locked in about 20 seconds which was faster and before anyone says anything, I did a soft reset in between to ensure the port was closed when I tested.

I know the comment has been made that changing to 4 does absolutely nothing but I beg to differ on that one. Seein is believin....

I'll still have to say, locking in a minute or less is acceptable to me for a free utility ;)

One last thought, for those who can't lock. Have you edited your registry?
[Mogul, XV6800 ROM Development] Scott:
I don't think it was server congestion at 3:00am. I'm really thinking maintenance.

Go ahead and humor me here, what did you do int he registry again? Im going to just try it for myself and see. Thanks!
[Mogul, XV6800 ROM Development] lllboredlll:
Read my previous post. I must of been editing when you read it the first time.
[Mogul, XV6800 ROM Development] joojoobee666:
I'd take a minute ANY day, but I can't even get a lock today. I've been tryin' all different combinations of registry settings as well...
[Mogul, XV6800 ROM Development] jimnutt:
Yup, it seems to be working again here to (Central NY). Must have been maintenance or something...
[Mogul, XV6800 ROM Development] lllboredlll:
What PRI? If 2.03, did you try relocking and flashing the OEM with PRI1.35 then unlocking and flashing a custom ROM and GPS radio? The PRI won't truely roll back but I think (just an opinion) that it rewrites a certian sector of the eeprom memory which will enable you to use 2.03 after going back to a GPS radio.

It has been working all morning for me. I'm in NC and intially tried it at 5:00am when I headed for work. Been messing with it all day.
[Mogul, XV6800 ROM Development] nitro66215:
Is anybody actually getting any data in the GPS part of FieldTrial?
[Mogul, XV6800 ROM Development] joojoobee666:
*POOF!* and just like that, I'm working again as well (Ohio) ... Changed all my regs back to the way I had em yesterday, fired up Google maps and walked out the door. 15 secs later, I had 4 birds. Musta been maintenance... We'll see...:eek:
[Mogul, XV6800 ROM Development] nitro66215:
Shi*... Try this.... Bring up Garmin / Google maps... have it running... Bring up Comm Manager... and put the phone in Flight mode. Then go back to the programs. I got instant lock... then put back into regular mode.
[Mogul, XV6800 ROM Development] Scott:
Yes, because its different. Im going to give it a try. Thanks!

BTW: Anyone locking again besides me?
[Mogul, XV6800 ROM Development] coffey_joshua:
i live in greensboro and i haven't been able to get any locks today at all
[Mogul, XV6800 ROM Development] tbhall77:
Where can I get FieldTrial? I've read it is suppose to be in \windows but I do not have it.
[Mogul, XV6800 ROM Development] lllboredlll:
Odd cause I started in Albemarle and it was fine. Been in Charlotte since 6am and it worked here too. I don't know why you wouldn't be able to get a lock. I got 5 locked when I started it in my driveway this morning. It increased to 9 and 10 once I started driving.
[Mogul, XV6800 ROM Development] gc14:
If you've installed your Verizon carrier cab (from the last time you flashed a rom), dial ##33284 then send. It will open FieldTrial, then you have to select GPS from the menu at the bottom.
[Mogul, XV6800 ROM Development] tbhall77:
I've got locks in under a minute inside my house. I'm currently testing Shadow-Tech's settings so my phone is setup different then anyone following GC's instructions.

I got Position Calculation set to "mobile" in QPST. Reg settings set to VZW IP/port, EnablePDEIPFromNV=1, and GPSMODE=2.
[Mogul, XV6800 ROM Development] nitro66215:
You won't see FieldTrial. It's hidden. Do ##DEBUG... ##33284...

Edit: Damn..... I must be having a slow day... GC Beat me to it.
[Mogul, XV6800 ROM Development] tbhall77:
I have information populated in the Setting column for GPS.

BTW, Thank you and GC for the FieldTrial info!
[Mogul, XV6800 ROM Development] Zenoran:
Humm... well I'm in Ohio and still not working :( Wonder if PRI update broke it for me :( anyone on new PRI still working?
[Mogul, XV6800 ROM Development] nitro66215:
Do you get any signal whatsoever in GPS Viewer?
[Mogul, XV6800 ROM Development] calash:
Since we are using IP, could it have been a routing issue in the Verizon network? Perhaps a switch was having problems and some of us were on the wrong end of it.

In any case I was never without GPS, just back to my usual lock times. This afternoon I was getting 10 second locks, but that is normal for me. I will test tomorrow and see if anything has changed.
[Mogul, XV6800 ROM Development] Zenoran:
ok went outside again and it's working now.. apparently absolutely NO luck getting to work in my office... I did go outside to try earlier and it wasn't working so apparently they did have the servers down at some point for maintenance or something.. hopefully they were upgrading to accomidate our hungry needs! ;)
[Mogul, XV6800 ROM Development] Skywing:
After flashing to DCD's 3.2.6 release and then back to MR1 and switching back to VZ Navigator (and deprovisioning/reprovisioning it for my account, I can confirm that it's being handed back a new PDE IP. Whether this is due to a load balancing at provision time when first installing VZ Navigator or due to some other change on their backend, I don't know for certain.

Edit: Both the old and new PDE addresses are still listening on tcp/8888 from Verizon addresses. Seems like it might just be a secondary server for load balancing purposes. I'll see about hacking something up to force VZ Navigator to use the old PDE addressing information that I acquired a few days ago and see if there's any change later on.
[Mogul, XV6800 ROM Development] nitro66215:
So you're saying that we will need a new PDE IP set in QPST?
[Mogul, XV6800 ROM Development] Skywing:
No, all I am saying is that the PDE IP that VZ Navigator was provisioned with does no longer match the one posted on the thread, which is also the one that I PM'd to gc14 before.

It's possible that Verizon has a pool of PDE servers and you get pinned to one [in the configuration sent to VZ Navigator] when you provision your account [for VZ Navigator]. Without trying to use the old PDE, I can't really say anything further, as that's all the information that I have right now.

Edit: Clarifications.
[Mogul, XV6800 ROM Development] nitro66215:
Understood. Thanks. I'm still trying to get a lock. It was working great the other day.

DCD 3.2.6

Radio 3.42.50

PRI 2.03_002
[Mogul, XV6800 ROM Development] Scott:
Ummmm, You werent kidding were you? The sats did indeed pop up faster. Cant lock because of physical location so will try in a half hour on lunch. I cant say this happaned because of hot start or not. I will play around for a while. But yes, I can confirm this does make your sats show up quicker. No doubt. I concur.
[Mogul, XV6800 ROM Development] Zenoran:
What is the significance of putting the server and port information in the registry? Isn't this just read directly from the ROM u update with QPST?
[Mogul, XV6800 ROM Development] serfboreds:
Could this turn into the same situation that is going on for FTA (Viewsat Extreme and similar) where a new code/PDE IP needs to be posted online when it rolls?

How does VZNav acquire the changing IP addresses? If we wait long enough will we see repetition (i.e. the pool concept Skywing spoke of)?
[Mogul, XV6800 ROM Development] psternklar:
Party is back!!

Now working in Albany, NY again. Lock inside 5 seconds.
[Mogul, XV6800 ROM Development] nitro66215:
Um.. yeah... I know what you mean. That would suck.
[Mogul, XV6800 ROM Development] Skywing:
I haven't focused on analyzing that part of it. VZ Navigator will wait forever if you're connected via ActiveSync, as it wants to only do network I/O over the cell link, which is a pain as the WinCE VS debugger requires ActiveSync RAPI as a transport. Due to the incredibly crummy nature of the VS debugger for WinCE and its inability to even show a call stack > 1 frame deep, much less resolve even export symbols, tracking down where it's waiting at has been a pain. I'll probably eventually take a look there, but if Autodesk was at all smart, the Autodesk LPS server will only hand you back configuration if you provide credentials to an account provisioned (i.e. marked as billable) in their backend.

This doesn't necessarily mean that the PDE that was originally posted doesn't work, however, only that I got a different one handed back to me when I reprovisioned myself with VZ Navigator. As I mentioned before, for all we know, it's just a load balancing and/or HA mechanism.
