Issues with returning to stock

I tried this method with no luck (I own two XV6800 and neither will get the internal GPS to work) and tried to roll back the changes. No problems connecting to the phone with QPST and I can load the backup of my original and shows the greyed out GPS portion (stock config). Then I write it to the phone, do a reset and check throught QPST (loading from phone) to find out that the settings have not changed back to stock (greyed out).

Anyone else experienced this problem? Just a suggestion would be to include instructions on how to roll back to stock (even though it is fairly obvious) on the wiki.

Any help is much appreciated......

-J

btw, I've got a XV6800 that I've completely disassembled to fix (pretty easy) and would be willing to monkey around/provide help with how to work on the internals if anyone is interested...

Hello,

Just wanted to post my results, even though they did not match any of the prerequisites. The only reason that I am is because I was scared to try it, but really wanted a functional GPS. My GPS has always worked, but was really slow to get my Garmin up and running with the first lock. After I flashed no2chem's kitchen, my GPS would take anywhere from 5 to 15 minutes sometimes to get a lock. This to me was unusable! I found the wiki, and wanted to say THANK YOU GC! I can now get locks usually in under 10 to 15 seconds even after a soft reset. I don't have to use any other software either.

Rom: no2chem 5067

Radio: 3.37.20

Carrier: Alltel

Thanks,

hinds73

if it matters to add this anywhere, going to stock Verizon radio/rom (and possibly the relocker) will undo this fix. it needs to be reapplied if you go to stock.

question

I have seen and read the Prerequisites and I have went through almost all of the 20+ pages but my Q is I am running a 3.56 ROM and I dont really see anyone else saying they are using this as most are 3.2.x. So can I still do this or not. My radio is 3.42.50 and just for clarification I have a xv6800

Alltel GPS turn on for GPS use

Go to this link for fix;

http://www.lancelhoff.com/2008/05/10/easily-enable-gps-on-the-alltel-htc-ppc-6800/

Alltel HTC PPC 6800 phones ship with internal GPS functionality disabled by default. However, the HTC PPC6800 contains a chipset that supports GPS. The Alltel wireless carrier has simply chosen not to include necessary GPS drivers with their phones. It is possible to get the HTC PPC6800 internal GPS chipset fully functional and working and simply requires installing the essential drivers to turn on the internal GPS features. The GPS on these HTC 6800's uses the 911 service to track your location. So of course this option must be turned on under your phone settings in order for tracking to work.

How to Enable GPS on the Alltel HTC PPC 6800:

NOTE: No warranty is being offered for the following information. Continue at your own risk!

Make sure that your Alltel HTC 6800 has been flashed to HTC ROM version 3.35.671.9 before proceeding. You can download the ROM from HTC.

Download Google Maps and install to your phone (Used later to verify GPS works)

Download EnableGPS.zip to your computer and unzip it

Copy the EnableGPS folder to your phone using activesync

Using your phone, open up File explorer and navigate to the EnableGPS folder

Click and run each file in order (they are numerically labeled 1-4)

After you have finished running each file in order, power off your phone and power it back on (or use soft reset)

Once your phone is up and running again, navigate to Start -> Settings and click the Phone icon

Click the Services tab, Select Location Settings and then click the Get Settings button. Ensure that 911 service is ON (box checked)

Start up Google maps and navigate to Menu -> Use GPS

I've got a Telus P4000 running ROM 3.54.661.1 amd Radio 3.42.40. Think this GPS fix will work?

My device doesn't lock onto a single satellite even outdoors and i've been looking for some info on getting that going. Any help would be greatly appreciated.

Thanks

M.
[Mogul, XV6800 ROM Development] unL33T:
GPS fix works on the latest Telus ROM I hear as long as you use the Telus PDE servers. The information for those servers is floating around this forum somewhere.

When I installed the latest Telus update it borked my GPS and I didn't know the Telus servers so I managed to revert the PRI which also worked. I'm not sure what the loss is with the older PRI but my phone works pretty good (including GPS).

Fix Works for Me

It seems the fix works for my 6800, as I am now getting SAT locks within a minute using Google Maps as my test. I followed the same priming steps too.

This is inside my home next to a window, where in the past it would take 5-10 minutes to lock.

Steve
[Mogul, XV6800 ROM Development] gc14:
Awesome guys...I'm glad it's working out for most people.

I should also note that you only have to do this one time. It will remain through flashes of both rom and radio.
[Mogul, XV6800 ROM Development] dcd1182:
oh yeah, you raise a good point. if people still have crappy fix times after this, they should change that key back to its default =2.

90 seconds is about average/working normally for an initial lock in standalone mode.
[Mogul, XV6800 ROM Development] gc14:
dcd you able to get on aim...gotta talk to you about a few things...
[Mogul, XV6800 ROM Development] j-squared:
Works great!

I had similar success to surfbored from first page of this thread. Tom Tom is now locking almost instantly - as soon as the No GPS message goes away - almost instant lock. That never happened before.

I'm using Verizon, DCD 3.0.1 - ran through the procedure just as published and everything was ducky.

Thanks again!
[Mogul, XV6800 ROM Development] jshaas2:
i feel stupid for asking this and i'm sorry. i just reflashed to DCD 3.1.6 and now can't find my Quick GPS tab. Before i went through the wiki of installing the GPS fix that gc14 has available, i wanted to try GPS on 3.1.6 with Quick GPS as my primer first. I've searched this forum, googled it, etc. and kind find the Quick GPS cab.

Can anyone post that for me, or bettet yet, if any of you like a better gps primer, feel free to let mek now. I know there are several out there and quick gps worked for me when using 3.0.4, and i'm curious to try it with 3.1.6.

thanks guys.
[Mogul, XV6800 ROM Development] gc14:
QuickGPS is not a primer. It's a tool that downloads information about the sats to help you acquire a lock faster.

Primers include software such as GPSViewer, BAF's GPS Toggle, and AstroGPSLauncher.

Here's the cab anyway.
[Mogul, XV6800 ROM Development] jshaas2:
thanks man. congrats on your celtics by the way. i love the lakers and Kobe, but the Green Machine had his number.

I used quick gps with 3.0.4 and it worked in seconds. do you think i need a primer with the current radio and rom instead? i thought quick gps was a primer, but guess i should have known better.
[Mogul, XV6800 ROM Development] gc14:
Yeah man DEFINITELY felt good bringing home #17 considering I was only 4 the last time they won a championship. Last night was total domination lol.

I'd say just do what you'd normally do for GPS...if you're noticing troubles, then use GPSViewer as it's what I use.
[Mogul, XV6800 ROM Development] Cycomachead:
Is it possible to do this from a Mac or linux box? Or on the phone itself? My new (replacement) phone should be here soon and the fixed computer isn't back yet...
[Mogul, XV6800 ROM Development] jshaas2:
Total domination is right. I'm tired of the Kobe=MJ talked. Kobe is best player alive, but never another MJ....although i was a huge Bird fan. :)

Do you use the Holux version of the GPSViewer? If so, i may try that.
[Mogul, XV6800 ROM Development] gc14:
Haha I wouldn't say best player alive... Paul Pierce is definitely up there with him, only difference is that Kobe has had great support in his teammates to let him achieve success. Now that Pierce has Garnett and Allen, it's a whole different story. ;)

Yes, I use Holux GPSViewer.

P.S. Who wasn't a huge Bird fan? haha
[Mogul, XV6800 ROM Development] kashabrown:
Excellent fix - followed your instructions and 15 secs later had satellites..

Congrats (grrrrrrrrrr) on the Celtics (Knick fan here) - they played the best and deserved it!
[Mogul, XV6800 ROM Development] jshaas2:
gc14 i'll have to use your new fix. the Holux Viewer would see maybe 1-2 satellites in the "N" area, but never see anything else, and never lock on anything. i let it run 10-15 minutes. I'll try to this new fix and go from there.

thanks for your help so far.

[Mogul, XV6800 ROM Development] crwinger:
quick question, for what reason can we not use this for sprint, along with your prior post with the "instant GPS fix for sprint?"
[Mogul, XV6800 ROM Development] dcd1182:
sprint already sets everything you need using the PRI. this procedure can only do harm for sprint users.
[Mogul, XV6800 ROM Development] kflipproductions:
nope =p...my sorry
[Mogul, XV6800 ROM Development] gc14:
Uhh it's not needed for Sprint. Hence why there are two separate threads...one for Sprint..and one for all other carriers.
[Mogul, XV6800 ROM Development] serfboreds:
GC,

This fix stays on through Radio and ROM flashes, right?

Why would GPS=4 not work anymore (per DCD)? That seems odd to remove cellphone assistance in locking.
[Mogul, XV6800 ROM Development] dcd1182:
my understanding is that it should have never worked. i have no explanation for people's results changing that key in the past. gpsmode=4 uses a method that's not available to you.
[Mogul, XV6800 ROM Development] gc14:
You're absolutely right. I've also said the same exact thing in numerous posts in numerous threads about gps.
[Mogul, XV6800 ROM Development] serfboreds:
Thanks!

And does the fix stay through Radio and ROM flashes???
[Mogul, XV6800 ROM Development] maccaberry:
gc,

I am down in Australia at the moment (no CDMA) and since I got here 3 days ago I cannot get a fix at all, whereas back in USA I got a fix within a minute in most cases outdoors.

I thought I would give this a try to see if it could help my fix. But no dice. Still get around 6-8 satellites showing up in GPS Viewer but it will never fix. I have the latest (7 days 0 hours) data from Quick gps.

I know that the gps will have been a bit freaked out by the sudden 10,000 mile shift in location, so have left it on for up to 45 minutes in clear view of the sky to try to get a fix but still nothing.

My (external) mini freedom gps got a lock within a minute or so of turning it on.

I am not sure if I will ever get a fix while I am here in Australia, but I will let you know how my fix performance is enhanced by the hack when I get back to US.
[Mogul, XV6800 ROM Development] gc14:
Your signature says you're running 3.0.4...are you still?
[Mogul, XV6800 ROM Development] dcd1182:
try and re-run the sprint PRI. i've seen users at ppcgeeks claim their GPS goes out and they have to run it again.
[Mogul, XV6800 ROM Development] maccaberry:
Affirmative. I know that you had 3.1.6 as a prerequisite but since I saw someone comment that the hack persists after a flash I might try it before biting the bullet and flashing 3.1.6.

I assume I was mistaken and it will not assist 3.0.4??

I will have some time later today to flash 3.1.6 so I might have a go.
[Mogul, XV6800 ROM Development] maccaberry:
dcd, I am on Verizon. I assume sprint pri would not be advisable?
[Mogul, XV6800 ROM Development] gc14:
Yeah don't use the Sprint PRI...I think dcd thought this thread was the Sprint Instant GPS thread.

Flash 3.1.6, install carrier cab, and try again.

Also, are you using GPSMode=4 in registry? If so, change it to 2......4 is no good.

P.S. When you use GPSViewer, do you click Cold Start after opening the GPS?
[Mogul, XV6800 ROM Development] maccaberry:
You know thats a good question. I have tried hot, warm and cold start and I cant say I have ever seen much difference. I did however use cold start here in Australia a couple of times to make sure the gps new that we had traveled a long way and not to use previous data.

I'll flash 3.1.6 and let you know how I go.

You guys are fantastic. Not only making all this wonderful stuff work for us, but you answer questions in short order.

Appreciate the guidance.
[Mogul, XV6800 ROM Development] gc14:
I edited my post with a more important question...perhaps you were already responding before I was finished.

Are you using GPSMode=4 in registry? If so, change it to 2......4 is no good.
[Mogul, XV6800 ROM Development] maccaberry:
I am set to 2. I did try 4 a while back but I found it was of no help - actually made things worse I think.

Interesting thing though, I have found that if I dont have the Phone radio turned on (no need to sice there is no CDMA here) i cannot get TomTom to connect to either the internal or external BT gps device. I have to turn on the radio, connect TomTom to the gps and then I can turn off the radio again. So somehow the radio does effect TomToms ability to see any (internal or external) gps. But I guess this is off topic and should be in the TalynOne gps thread.
[Mogul, XV6800 ROM Development] EinsteinTaylor:
Working great here!!

I've decided that GPS Viewer is garbage as a primer however...When I first started testing, GPSViewer was still taking quite a bit of time to get a lock...then I discovered if I did an "Open GPS", then a Close, and then an Open again, I had an instant lock...

I then started testing with Google Maps, and Live search and was getting nearly instant locks.

I would like to find a primer that works similar to GPSViewer in showing each satellite and strength, but without the goofy issues...

Thanks for all the hard work
[Mogul, XV6800 ROM Development] coffey_joshua:
i had some issues and removed quick GPS and it worked well maybe you could try that? i don't see how that could be connected but it fixed me not having any birds being seen
[Mogul, XV6800 ROM Development] nickles96:
Nice. easy to follow tutorial.. thanks very much for this.

while i didn't notice any increase in lock time (still takes approx 30 secs to a minute), the amount of sats literally has DOUBLED.. i am now locked full on with 8, sometimes even NINE sats..

this has been a great little upgrade..

below find shots from Holus GPS Viewer, ChartCross GPSTest, and HTS GPS Tool.

thanks again for a great post!

running Verizon xv6800, 3.35 radio, No2Chem 5067

- GPSMODE=2
[Mogul, XV6800 ROM Development] gc14:
That is exactly what the fix is supposed to do. In my first post I said this wasn't a miracle fix and you wouldn't get instant initial locks. In fact, I said that I get initial locks between 30-60 seconds on Verizon. It's supposed to make it consistent and lock more satellites and that's what it seems like it's doing for you.
[Mogul, XV6800 ROM Development] viper8u2:
ok, I know I did things somewhat backward here

I loaded 3.1.6 yesterday on my 3.35 radio and liked the rom and things seemed fine. My gps however did not seem to be working that great. I use to get a lock in about 45 seconds before but with the new rom it would not connect.

I tried this fix and it didnt seem to do anything. I reread the instructions and saw that the 3.39 radio was required, doh!

anyways, copied all my stuff off my 2gb card, reformated to fat32 and copied the radio. did a soft reset and #228 and just tried again and got a lock in 10 seconds. Now I tried multiple times before with the 3.35 radio and had it was consistent.

I will continue testing but so far am pleased

Nice work
[Mogul, XV6800 ROM Development] gc14:
Sweet deal. Are you noticing an increase in sats?
[Mogul, XV6800 ROM Development] viper8u2:
to be honest I have visualgpsce installed and in my house I only show 4, I remember seeing up to 7 before

I will check tomorrow outside and try again with locking on. for me to do this accurately, should I reboot each time to do a fresh initial lock?
[Mogul, XV6800 ROM Development] gc14:
No..just wait until you haven't used it for a while. You are seeing increase in your initial lock time though correct?
[Mogul, XV6800 ROM Development] nickles96:
Firstly, why aren't you out drinking like the REST of entire Boston ??

and second, perhaps update your Wiki pre-req. , as I am running radio 3.35.04, and this was quite a success !
[Mogul, XV6800 ROM Development] viper8u2:
Just tried again, when trying to lock it would show up to 9 sats, took a little bit longer this time about 30 seconds but locked on 5 right now

Some of us do work day jobs you know....going out drinking during the week then being up for work at 6am isn't my idea of a good time. Trust me, I did my share of celebrating last night.

The prerequisites are there for a reason and will not be updated. This fix works best with radio 3.39.10. It's possible you're noticing improvements with the old radio, though probably not as much if you were using the new one.

Running 2.49.NO2.5066 with radio 3.35.04 on a bell 6800 running on the MTS network in Manitoba. When i applied this fix, i connected faster, but i would have to soft reset the phone before i could make or receive a call,

Every time i would try to dial, it would say the number is not valid, or the network is unavailable, please try again.

I made sure to disable the data after i shut down the gps app, and i even tried to turn on airplane mode, and then back on with no success.

I undid the changes, and all is well now.
[Mogul, XV6800 ROM Development] BillyB0y:
My father brought to my attention yesterday that he got a gps fix around a minute and a half. This was last night about 10:30PM EST. We both have Verizon and are using radio 3.39.10 and dcd's 3.1.2. I tried mine out as well and also got a fix in my house (which was a rare occasion prior to) in about two minutes. We've made no changes to anything involving the gps.

The past week or so when I'd try for a fix it'd take anywhere from 5 to 10 minutes or more outside with no cloud cover in the middle of my work parking lot. Now I have fix times of around 38 seconds after I do a soft reset and around 10 seconds after the first fix.

Times are nearly identical between Windows Live Search and Google Maps.

So I'm not sure if the "fix" for the Verizon gps issue is a placebo now due to whatever randomness has happened between last week and now or if it is actually providing quicker fixes. I have not applied gc's "fix" so I'm not sure what is causing the quicker response.

Apologies for not reading the previous pages and about what the "fix" was supposed to do. In terms of satellites I'm still only getting between 4-6 which works for me. Apologies once again.

how do I verify if I'm on gpsmode 2 or 4?? when I go in with regedit to HKLM/Software/HTC/SUPLAGPS/GPSMode I have a value of 0x--2 is that what the value 2 you are referring to?

It's not placebo. It's been verified by many people who have never even been able to get locks before.

[Mogul, XV6800 ROM Development] Cycomachead:
Hmm....I can't tell how much it's helping, but then I probably need to get outside. (After spending yesterday loading up XP on an old box just to try this and flash the replacement.)

GC what's your job and how did you figure this out?
[Mogul, XV6800 ROM Development] Cycomachead:
Also what else does this do? It seemed to me like service programming was a sort-of extended epst computer based editor.
[Mogul, XV6800 ROM Development] Keystone:
If people are stuck with a dialer without the expected keyprogram codes, then to enter the DRM mode you don't have to reflash to a different ROM or switch dialers.

GC, I just added to the Wiki page that we can directly enter the DRM mode by directly executing ..\Windows\DMRouter.exe /DIAG

Similar for entering EPST with ..\Windows\EPST.exe ##778

Easy to just create a properly configured link to such functions.

~~~~~~~~~

This evening I'll try the QPST editing on my dad's phone that has had consistently horrible GPS performance....
[Mogul, XV6800 ROM Development] gc14:
No, leave everything as it is. The only thing that should be changed in the registry is GPSMode, and it should be set to 2 (only if you've set it to 4). Nothing else should be changed.

As I've said numerous times...this is not a miracle fix. So far, it seems the majority of people (including myself) have seen a vast improvement. This fix is not going to magically enable you to receive locks indoors (though it could help). It is meant to improve initial lock times and help increase the number of sats.

QPST is not an "extended EPST computer based editor". It is the suite of programming tools used by Qualcomm to interact directly with the MSM7500 chip. It is not meant for end users and I highly recommend for people NOT to play around with it.

Oh, and I'm a Computer Engineer and I specialize in Embedded Systems Design.

Thanks key, I've also edited it again (for cosmetic reasons lol). I still think the problems people are having with phone codes is a result of bad carrier cab install, no carrier cab install, or alteration of dialer. I've never had an issue with phone codes or dialers on any rom I've used.
