I finally got it.
VZW AGPS INSTANT LOCKS.
Tested to work on any custom GPS rom/radio pair. Now also working with the MR1 update thanks to Skywing.
Persists through all flashes of the OS Rom and Radio. Works with both PRI 1.35_002 and 2.03_002, though it does NOT persist through a PRI change. It will have to be re-applied after, and Location On will have to be reset.
Complete tutorial can now be found in the wiki here:
http://wiki.xda-developers.com/index.php?pagename=VerizonAGPSFix
Well done!
What is the default IP for Verizon? I changed that IP so many times
Edit: Instant lock 6 - 8 satellites in a building where I would never get any. Outside my phone connected fine after 15 - 20 seconds. No I am getting instant locks. Excellent GC, very good work on this one!
You are the man gc, patience is a virtue
LOL you had to ask for this just AS I FLASHED UP!
im such a good tester too
Great job.
That's amazing!! Well done and thank you for all the hard work. I would love to test it out!
You have PM.
Quick Question
For the less then patient of us who were dumb enough to flash the new update with the PRI from hell, what is the best prep path for this long awaited aGPS update.
I have waited to see what the best cure is and I am less then convinced which method to use.
GC Rules!!!!
I am humbled by your wisdom.
For those needing the stock info look to the GPS FAQ on this site.
No need to pm me anymore...I've posted the instructions.
A lil bit of an acknowledgement would have been nice unless you got the PDE addressing information from someone else
That being said, can you verify for certain that there is a difference from using the nvram-supplied PDE data? My testing on the MR1 firmware has not yielded any differences yet on the standard interface. I suspect that it might be worth a try putting on the GPS intermediate driver module from that ROM instead of the one with the challenge/handshake obfuscation built into it.
Before I poke around with that, however, it would be nice to verify that the PDE I gave you does indeed have an effect that cannot be written off as warm-start standalone GPS, and that it doesn't require a VZ Navigator provisioning.
Edit:
You may be able to test this by putting the phone on Wi-Fi and seeing if there's any change, as the PDE is not accessible out of Verizon IP ranges (furthermore, VZ Navigator chokes if you put it on Wi-Fi).
works great! no surprise though. thanks GC youre the man

I obtained the PDE information for VZW a couple weeks ago. I've just been testing **** out since. I can confirm though that it IS using agps and not just warm standalone.
Where does one best obtain pri 1.35_002? I have 1.24_002 right now, but have the other two pieces already.
work perfectly. first time I've ever get a fix in mahanttan within 10 seconds.
It works great. Also, I changed GPSMode to 4 (instead of 2) in:
HKLM/SOFTWARE/HTC/supl agps
8 - 9 locked satellites indoors!
Thanks again, gc14.
Ignore missed post earlier in the thread.

good to hear, im outside of the city right now, up in binghamton, but live in Manhattan. always been frustrated by slow lock times with all the buildings. cant wait to get back and finally have quick gps.
btw, im also at about 10 seconds or less up here.
thanks to all who helped
Works awesome. I'm using GPS Viewer, and it now pre-populates 12 sats and instantly locks to 7.
Thanks, I appreciate all the hard work.
Is there a test result for someone who has gone from the MR1 firmware with the latest PRI to the dcd firmware mentioned by gc14, without poking around with trying to change back to the old PRI?
I would like to eliminate the GPS intermediate driver in MR1 as the roadblock here.

Hi
whenever i open google maps and enable GPS
it'll stay as "seeking GPS satellites (0)" for like 5 minutes.
After..it'll say "GPS Active (0)"
well how can it be active if it's 0?
2 seconds later it goes back to the seeking message.
The weird thing is...when it says "GPS Active (0)" it brings me to random places in my city. Meaning it DID detect something, but then lost it immediately again.
i read the GPS guide and did whatever it said already. I had the GPS working a few weeks ago...now it's not working...even after reflashing with different ROMs.
Any help?
I am also unable to get a lock. I have Alltel and today I have tried going all the way back to stock and tried everything from 3.35, 3.39 and now I am back at 3.37 trying out ppcgeeks Titan_3.49. Everything is working great except no GPS. Using the GPS Viewer if I do a scan it does find the GPS radio on com4 but when I start it I never get a lock. I have also tried using BAF's and QuickGPS. Anyone have any idea how to get this working. At one time a while back I did have GPS working on this device.
Thanks,
mr.ellsworth
edit: I forgot to mention I also have tried out several of the differnt kitchens today in my quest to get the GPS working again including dcd 3.1.2

I'm not sure if this will help - but I recently discovered that if ActiveSync is running while you are trying to get a lock - it will not lock. Stop ActiveSync with task manager and try again. I've been doing this for the last three days and get a lock every time now.
Try a free diagnostic's app such as VisualGPSce that will display the satellite status. Goggle Maps leaves you rather blind as to what is going on.
Sadly, we have discovered that not all Titans are equal and some have a hardware discrepency that greatly hinders the ability to clearly receive and lock onto the satellites. I've played with a few and my personal device consistently locks to 5 or more within seconds while another with identical software settings rarely if ever locks onto 3. Others have realised the same. Try waiting up to 30 minutes to see if any locks can be achieved -- if not then there's likely no software solution.
My kids are using the Moguls in our family. I removed a bunch of junk from the Sprint ROM but it is mainly as shipped. I cannot believe how fast the Moguls on Sprint acquire the satellites. It usually takes less than a minute and is often just a few seconds.
I use the Kaiser. It takes about 3 to 5 minutes sometimes to find the satellites. Sometimes I have to use the QuickGPS program to nudge it along.
With the Mogul, the fix is extremely quick. I wish my Kaiser was as quick.
I'm running a Mogul on Sprint w/ DCD 3.04. Locks take 10+ minutes, GPSViewer shows satellites immediately, but the lock just takes a while. I verified that ActiveSync is not running.
The Mogul was purchased in Nov/Dec last year.

radio 3.35.04 took me 10+ minutes at times, 3.39.10 takes me 10 seconds.
It still takes me 10 mins to get a lock with 3.39.10, i use the GPS viewer to check for the lock.. Even with QuickGPS it takes about 10 mins.. Once it only took 6 seconds after that everything went to hell haha..

I just upgraded to 3.1.2/3.39.10 and google maps locks very quickly. GPSViewer still isn't very fast.
I upgrade to 3.1.2 and 3.39.10 and now my GPS is out by nearly 5 miles
Guys, 3.1.2 / 3.39.10 is not your issue if gps isn't working as good as you'd like it to. If anything, 3.39.10 is MUCH better in acquiring a fix. It's pretty much an unspoken fact that the gpsone chips inside these titans are spotty and some just work better than others. Sometimes mine gets a fix within seconds, sometimes it's 2 minutes. It's a combination of weather conditions, location of the satellites, and the gps hardware. These phones do not have SIRF chips in them...let's get over it.
It's np, I reinstall 3.35 radio and now gps work fine
Something about 3.39.10 and my gps chip doesn't like each other...
My inability to get over something not working correctly has led to getting things working correctly at least for now. Since I had had GPS working quite well under the 3.35 radio and knowing that I had been jumping all over the place with flashing different radios and kitchens in my never ending quest to try things out it occurred to me that I don't know all that much about what actually goes on during a reflash of a kitchen or radio etc... I thought it could be possible that during all the reflashes that not everything is cleanly removed and reflashed. Being an Alltel user I took my phone all the way back to stock which for me was the Alltel ROM “RUU_TITAN_ALLTEL_WWE_2.14.671.3_1.40.00_Altel_0816_NV132_Ship”. I got everything back up and running on this ROM. I ended up having to enter the MSID and MDN etc... I then unlocked the phone using "titan_SPL_2.40-olipro" next having had success using Sprints 3.35 radio I flashed “RUU_TITAN_SPRINT_WWE_3.35.651.2_RS_TITAN_3.35.04_4350H_SPCS_AM_Ship” that radio back onto my phone and then flashed dcd's 3.01 kitchen. I then tried out the GPS and everything was working great. Having finally received my 2 gig micro sd card I reformatted it to fat32 with 1024 clusters and proceeded to flash the 3.39 radio using this method instead of using the test sprint ROM as I did before. I decided to try out a different kitchen this time and I put on ppcgeeks "Titan_3.49_WM6" then installed “dcd QuickGPS.cab” and "dcd VisualGPSce.cab" and my GPS is working better than ever. For all of you out there that still are having GPS problems I would recommend doing something similar to what I did here. I would be interested to hear if this helps.

I've tried your recommendation...however it did not make a difference
I don't know exact how you look at VisualGPSce.
On my "sig/nav" tab, there are a few vertical bars...all says 0...except two, which says 20 and 15.
Satellites in use: 0 (rarely 1)
Satellites in view: 0
Try resetting, or pull battery
After some experimentation, I now think that I can get out of the loop of not locking onto satalights buy resetting. Sometimes just turning off, other times a soft reset, and if that does not work, a shutdown plus remove battery seems to do the trick.
So, I downloaded the visual gps and I have good news and bad news. The good news is it is finding satellites so we know the GPS in my phone is working, the bad news is is isn't USING any of the damn satellites. When i'm inside my house it is only finding 1 but, when I go outside it is normally finding 3 with very strong signals and then picks up a few other ones that arn't very strong signals.
What do I do from here? We know the GPS is working, but it isn't locking. Maybe if I get it to lock somewhere other then my house and then come back it might work? I'm still under my 30 day free trial with Alltel and if I can't get this fixed I might return the phone. It is one of the main reasons I bought it and it's really pissing me off that it's not working right!!!

Sounds like you've got a bad GPS chip. If the phone is otherwise working out for you, you should bring it back to Alltel for a swap-out due to defective hardware. Do it while you are in your 30 day period to minimize any hassles with them.

Verizon 6800
ROM: DCD 3.2.0
Radio: 3.42.30
I've used multiple GPS apps so far such as HTC GPS Tool, GPS Viewer, etc and sometimes they see 1 sat, sometimes none. I live in Portland, OR .. there's definitely satellites above =)
I've let it scan for 30+ minutes.
I have gone through all the guides so far .. soft resets, turning on and off the GPS location, using astrogos loader before trying Google Maps, Navizon, Live Search, etc.
No dice.
Any ideas?
ever since I loaded this radio I have not been having luck getting gps locks either.
exact config as yours.
I also did the gps fix that GC posted
Would like to figure this out also
Well, if multiple people have the issue with this radio, maybe its a bunk release and we need to downgrade to something like 3.24.02.
I might try it later tonight if I get the chance.
EH, nm ...
http://forum.xda-developers.com/showthread.php?t=403280
Thats the release thread for the radio version we're on and people are obviously not having issues with it ... hmmmmm
Updates after more forum reading ...
I've done the GPS fix @: http://forum.xda-developers.com/showthread.php?t=400975
I'm set to GPS Mode 2.
Still no locks.
Edit:
Another question ... if when using QPST you see that your 7500 modem is on COM5 vs where on most people's its on COM4, does that mean I should set the External GPS option on the phone to COM5 and start using that for everything going forward? I've tested both with no discernable difference in results testing .. but thought I should ask.
This may sound stupid, but have you been trying it outside or inside?
When I first tried to get a GPS lock back when I did the 2.1.0 flash, I tried in my room for hours. Sat it by my window, and the battery eventually drained trying to get a lock, with no luck.
Once I went outside, it was a completely different story. Even having the phone by a window wasn't good enough... I had to be outside to get any kind of GPS lock with it.
Issue resolved. Must have been something wrong with the radio firmware I used because I loaded another one and it worked.
Would you mind sharing which radio revision worked for you?
i just did another update dialing #228 and option 2
After the reboot, I got a lock in less than 10 seconds. Might be a coincedence but oh well.
The gps in this is so sporadic, sometimes it locks immediately, most times it takes forever
????
3.42.30 works good with sprint. Actually i get fastest lock out there out of all radios!

if ur on sprint you should have run the sprint gps fix, which includes updating the spring pri. you should be getting locks in under 10 seconds.
you should also be very thankful that u arent on verizon like me and happy when u get a 3 minutes gps lock.
(sometimes takes me alot more)
i still havent decided if its a phone problem or a location thing.
I live in NYC, so wherever i go im surrounded by buildings...big ones, and lots of em, so im sure this has alot to do with my crappy gps times.
anyone out there on verizon in NYC who gets good locking times?
just wondering
thanks
I was in NYC for a week and never got my GPS to work the whole time I was there. Otherwise my GPS works fine.
Ok so anything I need to know? Besides backing up contacts/calendar, do I have to call Verizon or was this only for custom roms? Anything else before I go it would be helpful. Any mistakes or tricks you found out while updating too. Thanks. I am really scared (even with this offical rom).
edit: I MIGHT update. Still having doubts.
1) Install Update
2) Dial *228 select option 2
That was it. Just finished restoring my backup and installing my favorite apps seems to work just fine
wow.. you guys are actually using the VZW ROm.. after they Locked out third party GPS and Rev A is still ****ty?
You're better off using the custom ROMs that are out there.. they are more stable anyway..

I don't use GPS, I prefer other devices, and I don't use it for data, the only things I care about are if it makes calls and if the WiFi and bluetooth work correctly. Not everyone has the same priority for a phone.

What are you talking about? RevA was working perfectly for me with the MR1 update - I was getting speeds right where I should have been getting them.
And like the person above stated, not everyone's priority is on gps
I cannot do a full back up with Active Sync anymore? I guess the older versions allow me to do it.
I am just picking the official rom since there is less steps and less margin of error. But really I haven't decided on what to do just yet. I do have my own seperate Garmin nuvi I use.
Can you see what speeds your getting with Rev. A? Also why didn't you have to call Verizon. Is it not a complete wipeout like a hard reset? Thanks in advance!

When I upgraded from stock rom to the mr1 update, it did not wipe out the a-key or dmu settings, nor should it.
As for RevA speeds - I was consistently getting between 600-800kbps

I updated and I don't regret it one bit...I actually like the VZnavigator, I had it on my LGvx9800 "the V" and it saved me from being lost so many times that when I bought my 700w I missed it so bad I almost went back to the V...
I got google maps on the Treo but I had no GPS at the time, then I got my 6800 and flashed to DCD's latest and greatest and I loved it except it sometimes took 5 to 10 mins for Live search or Google maps to locate me and neither of them had turn by turn voice prompts...and by the time they located me I was so lost i had to get directions from some nearby address to where I was going without GPS....VZ Navigator connects in less then 10 seconds at my house and even at the Airport where I work...!!! I don't mind paying for things that I like...
I guess I am happy with my Rev-0 speeds.
Just tested it I got 1.17 Mbps (1198.4 kbps). Since I do not use my phone with a laptop I guess Rev-A wouldn't be needed as much.
I appreciate everyone for posting here. Thanks! Still its good to know I don't have to call Verizon like whne I had to do a hardrest. I will still wait on upgrading. Reading more experiences from people. But the need to upgrade is definetly diminishing somewhat with time. lol

Please be a little more informed before you post stuff that's false.
I'm not sure why using the 2.03 PRI instead of my 1.35 PRI would be advantageous? Can someone explain this to me? I'm not sure it's worth the update unless I'm going to get some functionality that I don't already have (already get GPS lock in 7-10 secs). Ideas?

Thx for asking what I wanted to ask...
anybody...?
Parcou, I think I may have asked a question nobody has the answer to! 94 views and not a single response! On a happier note, I'm now locking gps in about 7 seconds from a cold start, so at least my current config is doing what it's supposed to do. Only drawback now is that GPS Toggle, the program I use to prime the GPS, sucks the battery like a Tijuana prostitute. It does seem to lock ALOT faster than any of the other programs though, which is nice. I was suprised however that with GPS Toggle and iGO8 running that the battery runs down even while plugged in, how's that even possible!
more reliable gps lock
I took the risk and flash to the vzw official wm6.1 update and let the customization ran. The PRI 2.03_003 seems to stay with the phone even from flashing a custom rom.
With the new PRI 2.03_003, the GPS locking seems to be less spontaneous but more reliable. Previous PRI 1.35_002 let me see a lot of SATs but signals were bouncing back and forth. Overall, it's an improvement.
I have read quite a lot concerning the new Verizon update, and like the update itself, I see absolutely no reason to update to the new PRI. No gained functionality, just extra bloat and incompatibility.
The only reason people were excited about this update, was to hack aGPS support out of it, which has been done.

The sat signal bouncing has mostly to do with the Radio rom installed.
I have a related question. I followed GC14's instructions for updating the PRI without having to flash the new MR1 ROM (I wanted to stick with my custom). However, upon executing the WriteDMData.exe step, I didn't get any definitive response. I waited a while and File Explorer never seemed to reset to the top of the file list as mentioned in the included .txt file. I did confirm, however, that I needed to redo the GPS settings in QPST, so I know that something took place.
Which brings me to my question: how do I tell what PRI is currently installed? It's not among the data displayed on the bootup screen.
Thanks,
David

Use the settings | Device Information app. It has most all version numbers for your phone.
just checking back on this thread....I am still on 1.35 and all is great on the gps... I still see no real answer as to why I need to go to 2.03 but I will if I can get a solid answer as to why...I have gps'd after the fix in many spot across the US already...all is smooth...
I'm running dcd 3.0.4 with radio 3.35.04, pri 1.35_002. I haven't been up here in awhile and just noticed the VZW official ROM. I have been using the GPS with Google and LIve and love it, it works when it wants to work is the most annoying part. Sometimes I have to reset a few times, but it rocks. I tried the priming method, but didn't notice any difference.
So on to the question. I don't have an external GPS, I don't want the verizon navigator stuff. I'd like to get my 6800 to lock in on GPS more quickly and not having to reset the phone. What/which stuff should I use?
Everybody should be using the newest PRI available. The PRI isn't JUST GPS related, and ISN'T bloat by any means. The PRI provides instructions for the radio (where the 'RI' comes from in PRI) and affects all aspects of the radio, including 1xRTT and 1xEVDO. There shouldn't be any reason why anyone should still be using PRI 1.35_002.
Same here parcou. I travel all over the place and my GPS works GREAT with the 1.35_002 PRI, so I'm not going to mess with it. Outside I get a lock within 10 seconds every time.
I'm having trouble finding the info on updating the PRI. Anyone have a link? Thanks!
Me too Panth. I'm been browsing through the Wiki's and sticky postings and have found nothing.
Here's the answer you've all been waiting for, seriously
The 2.XX PRI (from a SPRINT standpoint anyway) allows your phone to utilize the aGPS (assisted GPS) towers that Sprint has. The 1.XX pri does not do that, so your phone WILL take longer to acquire a GPS signal. In essence, your phone on a 1.XX PRI is only using the standalone GPS, whereas with 2.XX it utilizes aGPS to get a faster lock.
Your GPS may work great, I thought mine did too until I updated my PRI, and now get locks faster (~ 5 seconds) and I get more satellites than before. Even inside, I can get 9-11 satellites in very little time.
There's your answer, and you can completely trust it.

I'm having trouble finding the info on updating the PRI. Anyone have a link? Thanks!

If you have the newest DCD rom, there is a link in the connections folder that will allow you to update your PRI. However, you can also do it (on Sprint) by going to your Windows directory and running PPST.exe
You will need the following for it to work:
(I've attached everything you need in this post so you don't have to search)
1. You will need your ESN number, by getting the HEX off of underneath your battery or by going to Settings --> Device Information and finding ESN (towards the bottom)
When you have this, enter it into GetSPC.exe (run from your titan) to get your unlock code for your phone.
2. Install the attached PRI Cab for 2.03_003 (the most stable right now)
3. Once you have your unlock code and you've installed the PRI cab, run PPST.exe from the windows directory. It will say "Proceed with the update?"
Say OK....that should be it.
When I tested this on my phone, it didn't ask me for the unlock code, but I stress to every one of you, it's crucial to have this if you ever need to do anything with your phone as far as programming is concerned, so it's not bad to have...write it down in a safe place, or put it on a .txt file on your storage card.
That should help you get to where you need to be....
If it says it failed, then you forgot to install the cab file first. Good Luck!

Is this is the same procedure from Verizon?

That's why I only mentioned Sprint...I'm pretty sure the PRI's don't work across carriers, I'll let someone step in and correct me if they know more about that.
I'd imagine it's specific though.
However, the procedure SHOULD in essence be the same.
I do know for a fact that the PRL's are carrier specific, so that would lead me to believe that the PRI is as well.
I noticed that myself and a few other people are having problems getting a quick lock (or at all) over the past few days. It took me a few minutes today to get a lock and I am wondering if anyone (GC you still out there?) can test if the aGPS server was changed or if there is a reason this is different. I went through and nothing has changed for me.
I am willing to reflash to test but wanted to see if anyone on verizon could verify problems or an IP change for the server.
I noticed the same thing today..Took a long time.
I had problems too yesterday. Later towards the day I got it real fast again. Today still fast. Glad to see I wasn't the only one.
What is the current IP for the QPST method fix?
I tried the tutorial by GC14 for the first time, today, and I couldnt get a lock at all
Was is the same issue you guys had? Or did I do something wrong.
I have now tried this with a DCD rom/radio and the MR1 rom/radio, both gets no fix at all, and I tried it outdoors in open area away from buildings.
Whats the deal? (and what's the current IP please)
Thanks
I noticed it yesterday (3/4) but I just saw this thread and figured I would try it again. Got a lock in 3secs.
As of yesterday I can no longer get GPS locks at all. No matter what the application they sit there waiting for the GPS forever. Before yesterday it would work flawlessly and under 5-10 second locks. now .. nothing.
Anyone else still having trouble?
Also, does anyone have a link to any updated configuration requirements, such as the newest IP, etc? I can't find the instructions page on the wiki.
Thanks!
Soft-reset your phone.
No problems here, usually in under 10 sec

That is always the first thing I do after checking settings for any problem. I have been around for a while and try not to start threads unless I believe that it may be a situation that is not just me floundering around. I saw some other people complaining here and on PPC geeks about how it seemed that aGPS wasn't helping to lock, and it was confirmed by a few, for whatever reason.
I think it may have been a regional problem, or something to do with the towers that was isolated to the past couple of days. Today this evening it was back to normal.
Things have changed a bit after VZW picked up Alltell towers. Someone correct me if I am wrong, but VZW was previously paying Sprint or other providers to use their towers and then picked up Alltell towers that had some of the same coverage, VZW discontinued paying Sprint to borrow the signal for that area even if the Alltell signal is weaker.
I have driven an hour to work for seven years and days after the acquisition there are new dead spots in places that always had great reception, now it drops like clockwork in the same exact spot. It may be that the technology for those towers are being upgraded and they are working out some of the bugs, but what do I know.
HELP - No satellites, no lock, nothing!
ARGG! Someone please help. Here is the deal...
I have a Verizon Titan, and was running DCD 3.2.6 with 3.42.50 Radio. I decided I wanted to try the MR1 Verizon stock rom, so I upgraded to it and it's included radio. Then I did GC14's QPST tutorial for Verizon on his wiki page. It found satellites in TomTom, but would NEVER get a lock. I didn't like it, and the ROM was kinda slow anyway, so I flashed back to the previous DCD 3.2.6/radio setup.
I now do not even get an attempt at connecting. When I run TomTom is just searches for satellites for ever, but never even finds one. So I am not even finding the satellites, much less locking on. What happened? Before I did any of this I would gte a lock in about a minute or two. Now I cannot even find satellites!
HELP
Hmm, I misread your first post, I swore I saw you say you had Qwest, oh well.
Anyways, install an older Verizon rom that was pre-gps and then go thru the normal steps to unlock, and update the phone. Never install MR1 or MR2 again unless you want to have to do this all over again.
MR1 and MR2 both disable GPS via a PRI update that prevents any non authorized app from accessing GPS, tho there is a tool you can add that will allow some gps apps to work, but it only works if you leave MR1 installed, if you downgrade back to 3.2.6 without following my instructions above, then it won't work, period.

Quest? hmm, no not me, been Verizon for the past 5 years.
Anyway, I relocked and downgraded to the 2.09 stock verizon ROM and old SPL. Now, I upgraded to the 3.42.50 radio and 3.2.6 DCD ROM. I discovered that there is a new TomTom version out, so I am currently aquiring that with new maps and all, but is there a program I can use NOW just to see if I get a fast GPS fix? one that doesnt have maps or anything, just a satellite status application basically?
-thanks, crobs808
I remembered I could use GPS Tuner, so nevermind on the request. I will post what happens after I figure out the new TomTom 7.915
Holy Flippin Cow!
I have a GPS fix deep inside a building, lol. WOW. Thanks everyone for the help, you guys are truly amazing at what you do, and give without reward. Thank you
Now using Tomtom 7.915 with USA+Canada maps 825.2159

GPS issues are resolved for me too, and the new Tomtom is faster.
