GPS Not working?

I have tried villian rom and modaco rom but when i enable gps sattelites in the phone option it says its enabled but gps applications never get a fix and the satellie symbol doesnt ever appear in the task bar. Also I dont know for sure when this started happening because i have not tried using gps for a while, but would flashing the hacked spl cause it? are there any fixes?

I have tried Villian 5.2 and aHero 0.7, with Radio 63.18.55.06JU_6.35.09.26.
GPS get a lock, short time later it lose the lock.
Tested with different Software (GPS Test, Igo, Navigon, Maps)

does the radio affect the gps?

I noticed following with my phone: GPS gets lock (with Navigon, Google Maps ...) and works fine while phone is connected to the 2G base station. As soon it's switched to the 3G, GPS losts it's lock. If 3G is disabled (*#*#INFO*#*#) everthing works fine. Also lock gets back as soon as 3G is disabled. I'm using MoDaCo 3.2 and did try two different radio ROMs: 63.18.55.06JU_6.35.09.26 and 63.18.55.06JU_6.35.08.26. Hope this helps.

on the 2.1 roms that are available atm the phone needs to be booted with gps turned ON, otherwise it won't find a fix. when you are going back from 2.1 to 1.5 (e.g. modaco) you need to reflash the radio to make the gps work again. that is valid for the JU 09.26 radio, not sure about older versions.

There was an issue with flashing some of the 2.1's and then going back to a restored ROM. I am using the Mr Bang Performance rom, but couldn't get a lock. The solution was to reflash the radio and it should work then.
I'd give that a go, it might sort you out.
EDIT: I see kerndog already pointed that out...

ah perfect, reflashing the radio worked! thanks guys

SLOW GPS FIX in android

Could someone Tell me why GPS fix is so slow (with every android build yet)?? most times it takes 5-10 Minutes to find satellites with googlemaps /copilot .. is this a Known issue ?? My location is the Netherlands..
Do i need to set the something in the startup.txt ?

Get gps status from the market to download satellite information for a quicker fix, mine works in a matter of seconds

Even with GPS status.. the thing takes a long time to get a lock

Try the solution presented here http://forum.xda-developers.com/showthread.php?t=738982 and report.

What did the trick to me was:
1. Updating QuickGPS, on WinMO;
2. Installing GPS Status and downloading assistance data:
::: Settings&Configuration : GPS&Sensors: Manage AGPS data.
I am getting consistently fast locks now But what made the difference this time was updating QuickGPS on WinMo... Check my sig for details on my setup.

It certainly isn't useless, as many users have reported this as a solution. For me, it was the solution that definitely worked. I've tried every other method, including editing gps.conf file, using GPS status, etc, and the results weren't consistent. But after I updated my QuickGPS on WinMo, I have been getting consistent results, every time I try, as short as 5 seconds to get me a lock.
As you should know, some settings in WinMo still affect your hardware in Android: e.g., look at the "calibrate g-sensor in WinMo" recommendation. I think this is also the case with GPS.

But! what you can do in wimo is also possible in Android: getting AGPS... with GPS status..
so getting Agps information is not the problem here..
Possibility's
The radio ? with some radios with my winmo devices it took 5 minuts to get 6 satelites and with other radios (like blackstone 13.32.24xxx) it took 10 seconds to get 11 satelites .. in 10 seconds..
So I really think its Radio related..
Or the gps sensor isn't working 100% correctly..
Shouldn't we test some radio's for best gps performance.,

What is radio blackstone 13.32.24xxx??? never heard of it before.

Worked for me, thanks !! (it now locks in less than 10 sec, in comparison to several minutes before updating quickgps in Winmo).
The problem with some people in this forum is that they have to be smart ass, they will argue with you that there is no logic in your fix, even though it works. Too bad for them.

I've tried different radios and that didn't to absolutely anything to the GPS performance on Android. QuickGPS, on the other hand, gave me results. Even just using GPS Status didn't do anything for me.
By the way, A-GPS and QuickGPS assistance data are different things. QuickGPS can be useful to you even if you don't any signal when you are using GPS on your handset (if, of course, you have downloaded before your assistance data and it's up-to-date). To use A-GPS, you need to have signal...
Why don't your try this solution and see for yourself? You just have to update QuickGPS on WinMo. If you are using a light WinMo ROM, with no QuickGPS, try a regular stock or cooked ROM. The latest ChuckyDroid is a lite version, but has QuickGPS, though.
Try it, and then tell us if it worked for you.

some settings in winmo affect your hardware in android 'cause winmo is used to initialize the hardware, so that it has a certain state when booting android. this is due to the fact that our android drivers cannot initialize hardware (yet), so winmo is needed.
why should starting quickgps in winmo help in android? as far as i know all that quickgps does is downloading satellite position information to help the gps driver to fasten up the calculation of the current position in case of a cold fix.
if this would help in android, it would mean that the satellite data is some kind of stored *inside* the gps chip. otherwise andoid wouldn't be able to access the position data (orbit) of the satellites.
or am i completely wrong? if so, please help me and correct it...i'm just curious

This is correct. The satellite data is stored inside the GPS chip (this is written in the help file of the "GPS status" app).
It could be that because the android drivers are lacking in the HD2, we can only read from the GPS but not write (this is why updating the satellites work from WinMo but not from Android. because android can't write to the GPS chip).

thanks for your reply!
ok, then some kind of "quickgps" for android would help too...
so winmo is not necessary/needed for gps to work properly.

Thats a Good Point!

Holy Cow it worked! I mean it works!
Who can argue with that?

Sat data is input to gps chip. And the data is usually good for 7 days.
So if you use quickgps in winmo to update sat data, it will also make gps fast in android too at least a week.
gps status app in android also has the ability to download sat data, but quickgps in winmo seems better.
DON'T THINK ABOUT LOGIC. JUST TRY IT. IF you now a place where winmo gps works very fast, get a gps lock under winmo and then boot android. You will see that Android now gets a lock in seconds too.
Most people have problems with gps because their gps.conf file is empty, or they are not "really" in open air.
Gps will get a fix more difficult:
- If the weather is cloudy
- If there are buildings near you
- If you are actually inside a building
- If you are in a vehicle and vehicle is moving fast.
- If you don't have the assistance data in your gps chip.
- If you force your gps chip to do a cold start (instead of hot or warm start)
- If you don't have a working reliable internet connection (to download satellite data to aid in calculation)
- If you have an empty gps.conf file
Sometimes if I can't get a gps lock quickly, before blaming Android I reboot to winmo and see it doesn't always get a fast lock. Environment is a huge factor. So before thinking it is an Android problem, reboot to winmo use quickgps to download sat data and wait for a accurate fix in google maps or similar app. (google maps will first get your location from google location server which is usually only accurate to several hundred meters. Make sure you wait for the actual lock with a few meters of accuracy.
Since you "have to" load winmo before android (as no nand boot exists yet) just download sat data every few days before launching haret. It would be a good idea to get a fix and then launch haret.

The trick with quickgps also works in my device. Now android is almost perfect. Camera, gps work, no freeze. I only want 720p playback.

This theory makes me wonder.
Why is there a xtra.bin in the windows folder?
If there was an issue with the GPS in winmo it was sometimes needed to delete that file and download it again via the quickgps tool.

I wish I could try the quickGPS solution but unfortunately I'm using a very light version of windows mobile and quickGPS wasn't included. I tried to download and install one but got the error message about it not being signed or trusted.
So I can't figure out how to run QuickGPS and take advantage of these fixes.

AGPS

I know this topic has been discussed previously, but I haven't been able to find the answer yet so here goes:
As I understand it, GPS is working in all/most sense and cm based builds however AGPS seems to be an issue all have in common. From what I understand AGPS is just a helper function for quicker GPS locking so even though AGPS isnt working, you should still be able to get a lock.
Now, since before we got nand based ROMs for HD2 I used haret to load android from my SD card. Back then I used GPS depended applications like c:geo for geocaching and car navigation progs, as well as progs for finding nearest resturant when I visit other cities/countries.
Been a while since I had the need for it, but recently with the nice weather geocaching for example have become an interest. What I see now is that none of the ginger/cm/non-sense builds I have tried have given me a GPS lock. I have tried the GPS fixes, flashed Norway.zip for tweaking my gps.conf, installed gps-status but no chance in getting a lock. and yes, I have been giving it quite some time, outdoors.
Anyone else having these problems? I see from screenshots on for example the HyperDroidCM7 ROM that you can get a lock, so its not a problem for everybody. Is my assumption on what AGPS is, correct? Any worarounds to get GPS functionality working? Strange to have these problems now, since it worked kinda well before
EDIT: tried now with [10.MAR.11][CWM] RAFDROID HD 4.0.2|Fastest Full DesHD|DATA2EXT|[Rafpigna 1.8 OC], still no lock

There's no driver support for AGPS, so the best we can do for now is to tweak our gps.conf and use gps status. If you can't get a lock at all, it could be a HW problem. If geocaching is a necessity for you, you could go back to WM and sd Android, use WM to grab AGPS data, then boot into Android.

I use that rom, but the 4.0 (really not much of a difference for me between the 4.0 and 4.0.2), and I always have a lock quickly.
1) Did you try installing the GPSFix.0.1 apk file and running it? that downloads a criticial file xtra.bin into your data folder.
Also try the 1.2 files and see if you have any luck, because I know in the 4.0 of Rafdroid, the gps works very well.

Same as Angeldeath, I use Rafdroid and it works ok.
Mine was faulty a couple of weeks ago and HTC warranty had to swap the board (and also did the screen, keys etc). In the end it would still lock but after a while it would freez or have no reception anymore.
But to be honest I don't like the GPS receiver at all in the HD2. There are numerous tests and other people to back me up on the tremendous jitter the receiver has which makes you jump all over the place.
A nice test is to place it in the car and switch on the cruiscontrol at 100km/h, or even worse at 180km/h. The thing will jump atleast 10% in speed.
When I need to drive or walk long trips I use my iBlue 747A+ 66 Ch Bluetooth GPS Logger which you can buy cheap on ebay.
That thing logs, is fast, deadly accurate and with the free 'bluetooth gps' on the market you can even use it on the HD2

The AGPS thing on WM and then booting into Android is a myth, there's an extenvise work being done to make AGPS work on Android for our HD2s, but they have not managed to get it working yet.
Android on our HD2 simply doesnt have any commands to load AGPS, and the chip itself doesnt save any data. In the remote case it saved anything, there's nothing on the GPS Driver itself to read it
Quick tip to get your GPS to work:
Load Google Maps, let it try to get a lock, if after 1 or 2 mins it doesnt get any lock force close the app, turn off then back on the GPS and reload Google Maps. If you still cant get a lock, let it sit for at least 5 mins, then Force Close it again.
after that it should get you a lock in less than 10 secs.
Easiest way to FC it is enabling the "hold back to FC app" option on CM builds.

[Q] GPS not working

Hello,
I have bought a HTC HD2 with a broken digitizer from my friend, fixed it by myself and installed tytung JellyBean 1.2 rom. Everything work fine (phone, WiFi, bluetooth), except no program can find any GPS satellites. All program shows that "GPS is on", or "GPS signal detected", but no matter how long I wait it can't get any signal from satellites. At first I thought that GPS antenna coaxial cable might be disconnected, so I dissembled my phone, but didn't find any problems. Then I made some research and tried to modify GPS.config file (to add NTP server), installed "AngelDeath" Instantaneous GPS Fixation v1.2, tried some programs, but nothing helped.
My phone configuration:
HTC HD2 (512)
HSPL: 2.08.
Radio: Leo_RADIO_2.15.50.14
Bootloader: MAGLDR v1.13
Recovery: Clockwork Mod Recovery 5.0.2.6
Tytung Android 4.12 NAND rom (with data on sd)
Maybe someone knows how to test if GPS chips is good (want to figure out if it is a software version or hardware)?
Many thanks!
P3tras
P.S. I do not know if GPS worked before. I didn't try it with stock windows mobile soft and the person whom I bought phone from didn't ever use GPS

About the gps issue...
I've been on NexusHD2-JellyBean-4.1.2-CM10 V1.3a, EvoHD2v10 ICS 4.0.4-full HWA, NexusHD2-ICS-4.0.4-CM9-HWA V2.8,
PARANOIDANDROID HD2 v1.5b, and a few other roms I can't remember...
It seems the gps works great when Wifi or mobile Data is on and can access the internet,
other than that it'll just keep on scanning until it spots a gps satellite.
I have a map app, that downloads the maps of certain countries or cities, but when I turn on gps, it just stay searching for a satellite...
once I turn on wifi and also turn on location services for google (all check on boxes), it takes secons for the gps to pinpoint where I'm at...
Not very good in rural areas where there's very little reception...
it seems miui roms made from langthang or possibly any gingerbread roms works well,
since I had no problems with the gps in miui, rafdroid or coredroid...
I did made a search through google using advanced search and the forums, but only found 4 threads, all but this one only a month old...
Maybe it works for you, get fasterfix from google play, and set it at your current location, then turn on your location services
in the settings, then use your map...
I have a EU HD2 currently running NexusHD2-JellyBean-4.1.2-CM10 V1.3a, which in my opinion is running great, minus the gps running offline...
Magdlr
data on ext
16gb sandisk SDcard
Update!! Looks like all I needed to do was put a check on wifi and mobile network location under
settings -> location access.
It might download gps data like windows mobile did when it needed to, but this time google doesn't tell
you that, it just does it...
I haven't tested it when I'm outside so I'll test it tomorrow. I'll post the results after.
current rom I'm using: NexusHD2-JellyBean-4.1.2-CM10 V1.3a, with same settings.
Another Update!!
Just got back from a computer hiccup, and yes, GPS does work offline, it took a while for my phone to pick up
a satellite, but only around 2 to 3 minutes on the second try, it seems that it can pick up in seconds with data
help, then it takes a little longer every minute or hour the GPS is used offline...
But that's my assumption on this process based on how it worked on windows mobile...
Also it's the same on my pad but that's another matter... All I can say is get a map software that download maps
into your phone, rather than the app constantly hogging/relying on your data connection, of course if data connection is
an issue, if not, disregard the last bit.

Problem with Wifi and GPS after switching back to WM

Hi everybody,
I used Schlunds SD Version of Photonic. Everything works fine. But after a reboot to WM I found out that my phone identifies itself with android-decb55ff... Also GPS can't get a signal.
So I restarted the Phone to Android to be sure I have turned on GPS and Wifi. I also tried to get a gps position without success.
So back in WM I couldn't notice any differences (DHCP with android-xxx, GPS without signal).
Than I tried several NAND Versions (Photonic, Phonerty, MUIU) ending all with the same result
Is there a way to reset the gps to factory settings like a sirf chipset?
How can I change the wifi name?

Hi, sorry for late answer,
what is famous about this SD version is when you turn off GPS it will turn in WM also, or use the Google's one SDCARD version..
