[SOLVED] GPS has stopped working - wtf is going on...?

Over the last few days I have noticed that my GPS is not really working anymore. I'm not sure if this is a result of some software I've loaded or whatever, but I've noticed a few people saying that they are no longer locking onto satellites and noone is really sure what they've done - although there is a thread about the new Clove extended battery and many have mentioned that it stops the GPS from working.
I'd like to get everyone who is having problems to post here please so we can try and work out what the cause is. Some have speculated that it could be the radio but I don't think it is, I've flashed every single radio available with no change...
When I first got my diamond, I was IMPRESSED at the speed and accuracy of the GPS. I would get locks in around 10-15 seconds and using TomTom 7 I found it to be extremely accurate with regards to my position on the map.
Now it SUCKS. The other day I drove and it took 18 minutes to get a fix. When it finally did I estimate it was between 50m - 100m inaccurate. Some kind of lag is going on.
As of the last two days, I cant even seem to track ANY satellites. Since then, like I mentioned I have tried every radio and still the situation remains bad.
- I'm running a cooked ROM based on the 1.93.xx.x. (Elite 3.0)
- Current radio is .11 which seems to work well for my push email. (.05 worked well too) Other than that over the last couple of days its just been push email, a few texts and calls and really nothing else special I'm doing with the device.
Can anyone having the same problems please post here with your ROM version and let us know what your experiences are.
Thanks.

I have the same problem
Rom 1.93 - swift.

I recently bought 'htc diamond'.
I have a doubt. GPS service is for 'FREE' or we have to pay?
My phone says 'GPS download valid: 4 days. It means i can download GPS for free until another 4 days? kIndly let me know I am a newbie.
thank you in advance

No.. Its just the GPS data thats used by the gps to get a quicker lock on the satelites.. Which then only saves you time.. It does not cost you anything besides the trafik it uses to update the data..

gps is for free, the "4 days" corresponds to the time which your device
has the almanach data for faster satellite lock in it's memory. after this time
quickgps will download the alamanach data for the next 7 days, and so on...
if you don't use this feature you still can use gps, but obtaining a fix will
take you a longer time!

I have noticed that it is also dependent on the Rom. I am into flashing different roms and have seen different behaviour of Gps with each rom.
But HARD reset is a must after each flash.
Let me know your findings.

Got my GPS working in TomTom..
Steps i took:
1: change in PPC the gps port to COM6 - So still at Baud 4800
2: TomTom - Gps configure - "Other NMEA GPS reciver" - Baud 4800 - "COM6"
3: Closed TomTom
4: changed in PPC the GPS port back to "COM4" - still baud 4800
5: TomTom - Gps configure - "Build in gps"
And done.

I have this problem- the GPS seems to get worse and worse after a hard reset or rom upgrade to the point where it won't lock on at all.
I have noticed that in TT7 a number of satellites are being found (in the gps menu)but they are greyed out. Despite this it just won't lock on however long i leave it.

I notized that I was sometimes unable to track any satellites because I swiched on "A-GPS" in the registry with some kind of editor. After switching it off the problem was gone.

Yes, Advanced Config destroy your GPS if you use it to turn on A-GPS.
Try reflashing the Radio with the same build as you are using already. It resets the GPS and did the trick for me.

How can you turn on A-GPS in the registry? Which key is it?
I have the same problems: when I use the GPS, it finds some satellites and not, and back it finds them, and not. When I use tomtom 6, the screen turns grey and colored every 5 sec., because it finds the satellites and not.
Sometimes it works good, but mostly not.
Can somebody help!!!

There is a little tool which is called "HTC GPS TOOL(S)", dont remember the exact name.. there you can search for satelites using the "cold start" option.. when some satelites are found, then push the "Nav. Init." buttion", dont close the program, just start TomTom and se if it did lock? .. Some reported this method working..

I did things a little differently to yourself, but certainly your general method has solved the problem!
Firstly, and I don't know if this is a result of the radio version I'm running but I only have COM4 and COM7. Running radio .11
Secondly, within TomTom I simply configured the GPS, I changed to other NMEA receiver, selected COM4, and Baud 4800, and then within about 10 seconds, I had a lock. This is after days of not getting a lock at all.
Restarted TomTom, switched back to 'Internal GPS Receiver' and almost instantly locked again.
Problem solved!
I had done many ROM updates and not noticed this effect, I believe now thinking back this must have been a direct result of updating the radio only from version .03 to .05
I will update the thread title.

Gps problems

I finally upgraded to the long anticipated windows 6.1 rom for tilt. And now im having issues with my gps. I have tomtom6 and gps today for faster identifying my position. But since I upgraded, now when I turn on gps today and even tomtom it cant get my position anymore. When I checked tomtom satellite finder, it found some satellites but it never turned blue when the gps is locked. I need help to get my gps working again. Any help would be great.

I had this problem too after i upgraded to 6.1. Some people suggested to install GPS Test. It's a very simple but effective tool for acquiring a GPS fix. Whenever im not getting a fix i start this tool and normally it gets me a fix within 1 - 2 minutes. After this, as long as you dont soft reset your device, all your GPS programs should get a fix immediately.

Thanks! ill give it a try and ill update ASAP

Unfortenatly, aGPS is not activated by default. Search for the program called Advanced Cofiguration, and install that. There you can activate aGPS - and after that, you will normally get a gps link within 5-10 seconds...

i checked and gps is enabled

GPS can not find satellites

Hi.to everybody in this forum.I have an HTC Diamond previously locked to Orange Uk now unlocked to all networks ....with your help.
But I face a great problem!!
GPS is not locating satellites at all!!!
Before you ask me if I have read through out the forum, YES I DID (A LOT).
I tried everything, HTC GPS tool , GPS TEST , hard resets ,soft resets ,mpla mpla .....everything...but no result.
CAN you help??PLSSSS
My Htc comes with the new ROm 1.93

you didn't get a fix from the beginning or was it already working once?
what app are u using?
the gps i configured correctly?
app sees the GPS module?
start in this way, then we can talk...

I had same problem ,after my provider update (the radio maybe) it solve the problem. check what is your radio version and tell us..

I hope i dont have to get involved into this since the phone was bought from ebay (UK) and I leave in Greece!!.Now phone is unlocked and I think I will not be able to contact Orange network for update.

Seems like your ROM version is kinda old,
Maybe one of the guru here can help you,
or update your ROM by yourself (your own risk)

com port 4, baud 57600, gps enables - this is what i use in iGO8 and works perfect
what is set in "setings->system->External GPS"? Here you can find some settings also
programs - com4
hardware - GPS HWport none , baude 4800
access - tick manage GPS automatically

Those are the settings I have as well!!

I lost gps functionality after flashing to a new ROM.
Radio .07 and doing a "warm start" in htc gps tools got it working again, now from cold (ie initialising device to getting lock) is 25 seconds. (20 seconds to initialize gps, 5 seconds to get a lock!)

Try using gps gate,it will automatically configure gps settings and then start destinator,it should detect the inbuilt gps receiver and give you a fix,I had exactly the same problem with destinator 7, it just would not detect gps after using gps gate everythings fine,hope this helps.

ok found it ..I will try this as well.

Please update your radio to .07. I had the problem of not getting a fix. The GPS Info showed many satellites but none would get a fix. I went for a radio update to .07 & now, even when the GPS signal is in RED I get navigation working.... perfectly. Touch wood

I am trying to update Radio to 07 with RUU but it just stays in 0%.
Any help plssss????

Changed the radio but still the same .It will not find any satellites.Maybe the gps chipset is %^$%$#.

ok, your GPS module is detcted, right?
In GPS test, can you see signal of satelites or not?

Flash your radio again and do intermediate hard reset before phone fully boots. If doesn't work flash both rom and radio (hard reset after each!). Just had the same problem on my diamond (solved today) and had it in the past on Kaiser. GPS detected, gps tool see sats but they are permanently red and flat (like they wouldn't have any strengh at all) And its always to do with radio so don't worry about your chipset.

I just read another thread and found this:

Hi,
After i had some GPS-Problems (no Sattelite link etc.) i tested many combinations on my own. At the End this works on two Diamonds:
1. Follow the "Unlock description" if necessary
2. Flash your ROM (i used the AZTOR V6)
3. Hard-Reset your Device! <- Important
4. check Com-Port
5. Cold Boot yor GPS
6. Warm Boot yor GPS
7. Hot Boot your GPS
8. No link-Problems, no Lags and very fast Sattelite link (after a few Tests: First Sattelite Link ca. 2 min. After first using GPS ca. 20 sec. to Sattelite-Link)
Important: After installing "Sensor-Lock" my GPS was completely Dead.
I don`t read the completely Thread but i hope this is a little bit helpful.
Greetings

No GPS after Radio installation...

... so guys i need your help with this...
I installed the newest HTC-Rom onto my XDA Diamond and the: 1.11.25.01 Radio. everything works fine instead of the GPS.
I tried with iGO Navigator 8 and TomTom Navigator 7 both programs recognize the included GPS but both don't get any Signal through it...
I dont know what to do know please help me... and is it possible to fix that WITHOUT any hardresets because i want to keep my configuration...

Are u sure there is no signal ? What I'm saying is that...even though you don't see signal (especially happens to me with SU Radio's) it still works. At least for me it does. Even when I don't see a signal what eventually happens is that it give me the coordinates from the satellite side and if you start to move you will hopefully your map will show this too.
If this doesn't work get Config. 3.3 and make sure that GPS is disabled.
Or
Just change your radio........doesn't hard reset your phone and non required after you flash. Hope you hard reset your ROM after the flash though!

when i try to use TomTom Navigator...
it hungs at: Waiting for GPS Signal, so i think there is noch signal at all..
which radio version should i try ??

Currently I'm back with 1.09.25.23 but all the Security Unlocked radio's had this symptom of not displaying the signal but it was there.

First time use of an app using gps takes a long time to get a gps fix.
It can take up to 20 min.
And make sure you're outside AAAHAHAHAHA

Try running quick GPS

TomTom GPS Problem

I have an inconsistent and strange problem with my gps fix. Especially with a cold start. Sometimes Tomtom Navigator gets a fix within +/- 2-5 minutes. Sometimes not after 20 minutes.
Strange thing: Google maps is always able to get a fix, even if TomTom is not able. Once Google Maps gets a fix, I can start TomTom and then he finds a fix too. So sometimes in order to get a gps fix with TomTom, I have to start Google Maps.
This is a problem, because Google Maps uses internet, which I don't want if I am in a foreign country(Belgium for instance).
I am running Energy.RAPHAEL.21901 With Coockie Home tab 1.7.1,
Navigator 7.915(9196)
Radio version: 1.10.OliNex(don't know if it matters)???
Just ask if you need more information. Hope someone can help me!

Do you have to disable agps?

I am too experiencing similar issues in Garmin, iGo, tomtom.......
they all seem to gat a fix relatively quicker and lose it. and stuck in a cycle of getting a fix and losing it.
BUT, applications like, gps speedo, gps dasgboard are working without any issues like that...
any ideas?
BTW, i tested many different ROMs available here with similar GPS issue.

I tested IGO yesterday and it gets a fix perfectly. On the other hand, yesterday tomtom suddenly started working:S.. I hate problems which are inconsistent XD!
I am going to test IGO a week. I expect it will always get a fix, since google maps also gets a fix whenever I try.
What I haven't done is upgrading my radio version. So that is my last alternative.
Keep you posted.
@ Argentocruz: I had already disabled AGPS

Mee too. Disabled Agps and tried. Result: same.
my radio ver: 1.08.25.20
should I try a dif. radio? if so to which one? anyone can suggest Pl. thanx.

Try a different radio yes. With the stock radio 1.something my fix was slow and I had quite some lag in TomTom. With 1.14.25.35 this issue was gone. It takes me about 1 minute to get a fix (and sometimes it doesn't fix, so I have to reboot the phone)

ok. will try this Raphael Radio 1.14.25.35.
Sorry for asking here... I downloaded this radio pack and it contains Raph_1.14.25.35_rilphone.CAB file also.
do I need to install this cab after flashing the radio?
10q.
BTW, anyone from Australia tested this?

Flashed the radio. problems seem to be gone..... tomtom, igo works perfectly so far.
will test more. thanx all for the support.
