[Q] How to make GPS work ?

Hi,
Since I am new to the DHD I still do not know the correct way to get the GPS to work.
I have the GPS turned on, and I launched the Navigation app and it says "searching for GPS". It has been searching since the last 30mins without any luck.
Is this a hardware or software issue ? Anything I am doing wrong ?

You sat inside by any chance?

Yes I was inside my room but I was standing by the open window with the phone outside.

Ok, I have had similar problems and posted similar questions....
the first gps fix will take some time....the 2nd, likely a lot less...
What worked for me:
- I have setup gps to not work with network (wifi or 3G), this means it only uses the gps module....
to get a gps fix, especially in the car, it helps if you put the DHD near to the windscreen, so it is better able to pick up the GPS signal...
when I was inside my home, it took forever to get a fix, when I now put it in behind the windscreen, my DHD with silicon case gets a fix in about max 1 minute....if I use the Wifi or 3g network it is even less....
hope this helps

Try the miui site gps fix
http://www.miui-au.com/howtos/faster-gps-fix/
It works extremely well for me, and i do it every time i flash a new rom.
You could also try
http://forum.xda-developers.com/showthread.php?t=1252011
I don't see that much of a difference, but i guess its because i don't have a network connection on most of the time.
You can also try different navigation software. There are heaps of free ones on the market, and they seem to get a much faster GPS lock (Than google or HTC navigation).
I just realised that this thread was from ages ago :/
I'm also not too sure how i got to this thread in the first place...

Get gps fix or gps status & toolbox from the market to lock
Sent from my HTC Desire HD A9191

try a few of the suggestions from Q14 from ARHD thread. Updating the gps.config file as described (Q14:5) sorted it for me. I get a sat lock in seconds now.

Problems with google maps, he remains paralyzed searching gps..

like the thread title says i have this problem.. my google maps is always "searching for gps" in the Navigation function
few threads ago i was posted a problem with GPS STATUS or GPS TEST...
They were not finding any satellite...
later with the help of @superstick1 & @blbean i was fixed it... now these apk finds even 7 satellites!!!!(often LOL)
but Navigation continues without work.... some suggestion?
i was tested:
1-reinstall the apk. (not fixed my problem)
2-erase data caché OF THE APP only (not solved my problem)
3-fix gps sat. with gps status(not solved)but 5 satellites found...
4-use FASTERFIX.apk and then restart my machine (not solved)
EDIT: ufff! i´m desperate more tries:
5-flashed another recommened rom from coredroid thread: 12.28g.60.140f_26.05.05.27_M3 (orange uk)but its weird because i´m living in spain (orange es) (NOT SOLVED MY TROUBLE)
6-flashed another kernel: from leedroid 2.2.9 to my current BUZZ 1.3.8.3 1.2 GHZ MAX(NOT SOLVED)
I AM GRATEFUL FOR YOUR HELP BOYS (OR GIRLS )

Have you tried using a different rom and/or kernel?

Hi SERGI.3210
We meet again. Lol. I notice from my own experience that if we often reboot our phone, the GPS state will be restarted. And hence it will take some time for the GPS to work again.
For example, I have once flashed LeeDrOid' v2.2.2 in the past few months(first time), and I got a fix very quickly. It will be within 5-15 seconds? At most it will take is 30 seconds. However, after I reboot for whatever reason(I forgot, but I am not flashing anything else), and the GPS takes more time to get a fix again. The situation got worsen when I am in the car to get a fix. Took about 5-10 minutes??
But after some time, tolerating such slow fix(I know, its annoying) it suddenly get back to normal again. Which means I can get a fix very fast again.
Many has recommended the use of GPS Status app to clear A-GPS data and then download them back again. It works for them it seems, but in some to a large extent, it did not really work for me.
Maybe you can try Ulysee Gizmos app from the market? It has the capability to download A-GPS data as well. Recently I try using it and it seems to fix my problem once again. When was it? Last two days ago. Lol. Now it still work fine. Hopefully this continues.
I am still use GPS Status to get A-GPS data. Which means I am using both of them at the same time. Probably both apps does fires out some solutions? Haha. Me not sure but you can try.
Cheers mate. =)

okay i´m going to test this:
-1-clear A-GPS data of the gps status.apk AGAIN....if not solves:
-2-download Ulyse gizmos.apk and try it...if not solves:
-3-I will go to area discovered to trying... if not solves... maybe i will go to reinstall the all the apk relationed with GPS..and if it not solves that
-4-I believe that I will think of burning my DHD.. lolololololol
thank´s for you usefuls posts man..
see you soon here
EDIT: i tried to install another GPS NAVIGATOR (sygic) BUT THE PROBLEM PERSISTS... i´m really sure that the problem its that my device finds gps when he wants And if it is clouded less still

I am fine here thanks. Getting ready for work now.
In your case, the problem is nothing to do with the navigation software but your GPS cannot get a fix. It may due to hardware failure.
If the situation persist, probably you should consider sending your device to HTC for a check. But make sure you turn back your phone into normal state first. (i.e. unroot your phone)

i pretty much have the same problem ...
5+ mins to lock my position ..
RcMixHD 5.5 and a changed radio... i will just burn it..

So you finally got a fix? Congrats!
Yea, try to send it to HTC for a check. By the way, again, remember to unroot your phone first before sending to them.

good night buddy!!!!
i have soo good noticesx100000000000
THAKE THIS:
gps status:found 8 or 9 sat.
fixed in 62 segs.
google maps:working perfectly!
finding gps at the moment
15 meters position error max. (better than my htc hero)
THE MEDICINE:
1--Though I feel sorry very much I had that flahs another CUSTOM ROM
2--Then I´VE flashed the recommended radio and was foun 3 or 4 sat...
3--and the most important: flash the RIL for this radio in this moment i was found 8 or 9 sat.!!!
the only one thing that i don´t like (nothing nothing) is the custom rom:
RCmix 6.1.0.1 (ported from desire s)
i´m COREDROID LOVER and RCMIX seems too simple but i preffer the good performance before beauty things...
Nevertheless when it does a few kilometres and tested well the GPS I will try with Leedroid (froyo) to see if I obtain the same results

Good for you buddy!
Usually if you got a fix pretty quick, it will have errors ranging to 30-50 meters(that is from what I obverse based on my device that locks within 5-15, max 30 seconds). Then it will adjust overtime. Well, still better than doesn't get a fix at all.
Hmm.. RCMis HD6.1.0.1? The Evolutionary Sense ROM? I have not try that yet.. plan to try after my exam. Currently concentrating on my exam for this month. Also quite satisfied with my current flashed LeeDrOid v2.2.3 ROM now. Lol.
Probably will be trying Miui too. I would prefer staying with Sense ROM as there is unlikely to have Premium Navigation in Non-sense ROM. If I would to try other GPS apps, I will have to pay for it. Premium Navigation is free for life for me in Malaysia + Singapore. Also finding addresses with it is easier, unlike other GPS app.(i.e. cannot search address). Probably due to the names of addresses here. Here uses Malay names and not English.

[Q] No gps with Android revolution hd rom

Hello there,
As the registration video pointed out to me that i'm a noob i have noob question.
Im running Android Revolution HD 6.3.3 By mike1986
with these radio thingies.
12.65.60.29U_26.14.04.28_M
But my gps isn't getting a fix. What is wrong with my phone settings?
Hope to hear from you.
Greetings
Youri

Hello.. Maybe try flashing the AGPS patch from this thread.
Here's the direct link... flash that through recovery and see if it works

And if you are having crappy GPS accuracy once you lock, your best bet is just to find some way to get a solid connection from the GPS antenna to the motherboard.

Question is if you've had problems with gps fix since flashing Mike's rom or has it happened after a while.
Next question is what navi software do you use.
I tried two navi programs: Google's and beta version of Automapa (although beta is closed for now)
GPS always gets fix after couple of seconds. With Automapa it is also very accurate. Google is worse than Automapa but still quite good.
Both programs were running on ARHD 6.3.1
Anyway I'd try reflashing with full wipe again. Or maybe try newer (or older) version of ARHD?
Regards
Rafal

There are several possibilities:
1) environmental - try again outside, in plenty of open space. Try with & without your case, if you're using one.
2) config: download FasterFix from the market and choose your preferred server (there is a preconfigured list, but you can also type your own in: Spain is es.pool.ntp.org France is fr.ntp.pool.org etc) also check out GPS Test, also from the market, and you will see exactly how many satellites are in view etc.
3) hardware - bad connection. If you can't get a result from 1 or 2, well maybe there is a bad connection (the GPS antenna is around the flash). This is unlikely, I'd say.
A reboot may help to clear the cache - as suggested above, a superwipe is the way to clean before flashing a new ROM. You can also clear caches from Recovery.

First do some testing before install any patches.
Go out under clear sky and after activate gps sattelites from settings, download and run from market the Gps Test apk.
Write us the results here.How many satellites and after how much time did you get.

I`maar also noob without same issue. Same rom and same radio.
Before flashing, gps worked flawless, after flashing no more fix.
Even the quality of the signal for calling is nota wat it was.
Tried 3 navigation apps, open area,... nothing works.
I really Need the gps, so i`m thinking of unrooting if there isn't aan sollution.
Or could this be solved by flashing an stock rom ? Any tips or hints are welcome
Thanks in advance!

Personally i reccommend this http://forum.xda-developers.com/showthread.php?t=1318892
it seems a bit risky,but it shouldnt be a problem opening the flash case. Im not into soldering, and im afraid of burn motherboard,so i just pulled up the golden springs a bit,cleaned with alchool, an voilà! fix in < 10 seconds with < 20 meters precision.
hope it helps.

It seems to me that if gps worked stock, the hardware is ok

Yeah try the Rom in my signature its awsome :thumbup:

I had problem with my GPS too. It's doesent a rom or radio problem. In other thread it's show how to hardware hack the GPS under flash cover of our dhd. I won't hardware hack so gently push down the flash cover. Go out and GPS status and gmaps fix in less then 10 sec.
Inviato dal mio Desire HD con Tapatalk 2

i'm noob with rooting phones, but not with pc's or other electric equipment.
If i say gps worked FLAWLESS on my stock DHD, how can my antenna suddenly be defected after flashing a rom?
I even went to open field with NOTHING in a 500m radius
it has to be something software....
i'll try to flash other rom like someone suggested...
already thanks for the replies!

check if GPS is broken?

I have the same problem! My GPS is running but it cannot find any sattelite!
Is ther any method to check the GPS if there is a hardware problem or a software problem?
Maybe there is a logging like "logcat" for GPS which i can check?

I'd recommend trying the app Faster Fix. You select your region, and it sets the correct GPS configuration data. If that's the issue, that app will solve it.
Also worth trying the app AGPS Inject, which downloads GPS assist data when opening gps apps like gmaps.
Also recently removed the letters "supl" from the APN type in the data access point settings. Resulted in a faster fix.

Thank you Swell6 for your tips, but nothing helped!
I think it's an hardwareproblem.
Does someone know where in the phone the GPS Module is sitting?

With the dhd there's a known hardware issue with the GPS antenna, which is part of the black plastic led cover. Over time it can lose contact with the main board, and sometimes just pressing it in can fix it. If it needs more, there's loads of posts on what can be done. Worth a try!

Problems with WIFI, GPS and radio after 2.17 update

A few problems with 2.17 / 4.0.4
After i installed the update 2.17 i notice that my wifi is even worse. I have i good connection with my Dynalink D635 router. So i don't think it is a hardware problem. But wifi works just sometimes. It was the same with 1.29, but al lot beter Now i loses his connection and than it come back, but mostly there is no data-stream at all.
Also the GPS is not working fine anymore. Lost connection a the time. It was working fine with 1.29 .....
The radio (connection with G/3G/H) is also worse. And sometimes he lose my sim-card and even goes into flight-mode??
HTC, i dont know what you are doing over there, but i have to say that this product is absolutly not what i suspected. I waited for the 2.17 to give the product a second chance, but it is even worse

Basic question. Still, have you backed up and tried Factory restore?

recently my phone doesn't read the SIM after a few hours of use. Says there's no SIM.

agree with the first comment. Can't confirm yet WIFI performance but GPS is now really bad. It was working great on 4.0.3 same as WiFi

I used only files from the instalation guide. No other modifications

CUSTOM ROMMERS
Just ensure you have installed the rom correctly, aswell as flashing the right boot.img for 2.17.401.2, then although it seems like a pointless task, please do well to include the command 'fastboot erase cache' before AND after the flash of the boot.img, just to be sure we don't have any kernel bits left behind. You could also go the extra mile and clear the dalvik cache in your custom recovery...
STOCK ROMMERS
You should ensure that your update was successful (check this in settings > about > software information) If the software version is 2.17.XXX.X
Then the update was successful, just double check your radio/baseband is what its supposed to be which is 2.1204.135.20 (i think)

I have a good question: Did you drop the phone recently or otherwise do anything to push the phone case down? It sounds like you crushed all the antenna contacts or your case just isn't seated right.
SIM losing contact would suggest that the SIM pins aren't fitted snugly against the SIM. You can either put tape on the sim to get to to fit more snugly or send it in for warranty repair.

I did not drop the phone, or did something strange with it. The only thing i want from a device that costs € 500,00 is that everything is does work.

I've have experienced a drop in mobile network signal after the 2.17 update. Haven't tested GPS but WiFi seems alright. I have not dropped the phone nor done anything unusual to it, just updated. Before, I had 5 bars/full signal all the time, and when I checked battery stats the network signal indicator throughout the day was green. Now, after the update the indicator is yellow and I have around 1-3 bars if signal.
Also, I'm in Denmark so I got the 1.29.xxx.12 update which was supposed to optimize signal strength. So right now I hope they are working on a similar fix.

The Custom ROMMERS part worked for me.
I had the same Problem. Just checked after a half hour and it still works.
Just try this method

Dear all,
I was using the Lee-droid rom. I switched to insert coin rom 9.xx and even tried the android revolution rom. In both I had the same problem. Using wifi I have almost no data although the signal is strong. It just keeps trying to synchronize like for hours. But for some reason whatsapp conncection works and no problems there, but when it comes to loading the play store it takes ages (5 min. plus). I already searched the internet for solutions but haven't found one. When I use my providers internet, it also just keeps trying to synch (and for some reason never seems to complete??) internet is also really slow and it used to be faster on mobile as wel as wifi. Is anyone else experiencing this?
I am really desperate to get this working, I hope someone can point me in the right direction.
Edit: Confirmed that wifi does drop out sometimes and cant seems to get a signal although im standing right next to the router. But when I have wifi, I have a great connection, but almost no data, only whatsapp seems to work.

I can also confirm taht after the 2.17xxx update wifi is droping a lot. Didn't had that problem on 1.29. Also there are other issues but it will probably be best if I open a new thread or someone else does that, just for the sake that htc will read it and make our phones better

To me, your issues sound like radio related issued, although I could be wrong. You both on custom roms? With custom recoveries? I suggest if 1.29 worked better signal wise that you flash that radio in your custom recovery. That might improve your signal. Its basically different for everyone which radios work the best so basically it's trial and error.
Lemme know how you get on :thumbup:

I'm not sure if it's the same problem but i've been having a strange issue for a while. I believe is started when I began using jellybean roms (Not 100% sure). My phone will work for a day or two with no issues and then I just suddenly lose my gsm/3g connection. Numerous restarts later and if still doesn't work. Can't use it as a phone at all. If I reflash or change the rom, my connection works again for a few days and then then same thing happens. I'm having to reinstall roms every few days to have a working phone. I did have the pogo battery cover on for most of that time. Last time it happened, I removed the cover and I suddenly had a connection. I've left it off since, hoping it was just that but sadly not. Happened again to me just now

Hi, have you flashed any different radios? What's your current software version and does your Wifi drop as well? Or is it just mobile data?

After the 2.17 OTA update, the signal is always medium...but now there r no call drops or loss in signal

sandipbarik said:
I got my 2.17 OTA update last night, immedietly after the update my wifi signal was dropping, which was pretty stable 3 bars before that.
Today morning im getting dropped gsm signal...sometimes its showing no signal...eve a manual signal search gets me no network, omly airplane mode on/off gets the signal back.
I m not unlocked and not rooted...just plain factory stock.
should i unlock it and flash the radio from the 1.29 rom ??

That's up to you, but many users have experienced that some radios work better for different people. 2.17 works ok for me, maybe you should try.

GPS frustration!

I know this is a much discussed topic here, and I just wondered if anyone’s managed to pinpoint exactly why the Desire HD often has problems with GPS?
My reason for asking is that I was doing a direct comparison between my wife’s HTC Desire (my old phone) and my Desire HD. The Desire seems to get a super quick fix even inside our house, while the Desire HD sitting right beside it can’t even see any satellites. What is confusing is that the gps.conf file on the Desire only lists North America NTP info, and we’re in the UK, and even so gets a super quick fix. I’ve tried all sorts of approaches to get a better fix on my Desire HD, including hardware and software, and it still falls way short of the original Desire.
I’m using GPS Test which is a great app. I generally find that if I clear AGPS and then download AGPS data, I get a fix soon after, but as I say, with the Desire this is unnecessary.
Does the AGPS data achieve an actual fix, or does it provide a virtual fix?
Do navigation apps call up AGPS data, or do they rely on a hardware only fix?
One idea I have is to use the fantastic app Tasker to reset and download AGPS data whenever a navigation app is opened. This would need a simple app which resets and downloads AGPS data with just one click. Is there one out there? I haven’t found one. If not, would this be a useful thing to suggest as a development?
My feeling is that it’s essentially a hardware issue, given the fact that the Desire gets such a great fix even with wayward gps.conf settings.
I’ve replaced my old GPS antenna which had worn contacts with another, and have used solder on the contacts to give a better contact. I’ve seen other mods where people have soldered a homemade wire antenna directly onto the mainboard contacts. Is that the best way to go? As I say, I’ve researched this on this forum, but haven’t found a definitive mod. Is there an accepted mod for this?
If the issue is with the chip on the mainboard, I suppose there’s not much which can be done. I suppose I’m just exploring all the options for improving the antenna and getting the best software setup.
Sorry about the rambling post, but I’ve tried to cover everything going round in my head! Any help would be really appreciated!

I know I'm replying to my own post, but I seem to have resolved my own frustration. After weeks of searching I found the perfect app. It's called AGPS Injector, and it allows you to call up AGPS info when you open an app. It enables the creation of home screen shortcuts for any app e.g. Google maps or Navigator, which then opens the app via AGPS Injector, and ensures a quick fix. It really works well, and is as simple as it could possibly be.
ALSO, I found that deleting the letters SUPL from the APN Type in the APN data settings results in a lightning quick fix, on a par with the HTC Desire as in my original post. I read on a post somewhere that the Google supl settings sometimes don't work as they should, and actually disrupt the fix. No idea why, but there you go. Worth a try if you're having GPS problems.
Hope that's of help!

my mtk 6577 phone do have the same problems! i thought this is only happens with mtk module.
The agps need to be download and a reset . And i can enjoy a day of fast gps position lock.
Is there any tasker script , can automatically download and reset the AGPS state ?

You can use GPS status, in tools you download agps.
AssistedGPS is only assistance to better locating. It locks to your network cell, which can give even 1km mistake.
Open your led cover and raise connectors up a bit. It should help.

still problems here
Still problems here. it won't even see any satellites.
I tried raising the connectors a bit so they better touch the antenna. It made not difference. But I am sure this is a software issue anyway because it happened after I flashed a new radio.
Any suggestions? This is becoming frustrating.

Which rom and radio is on?

The main problem is the contacts in the led light cover ( which houses the GPS antenna) are very poor. Clean contacts and maybe use a conductive paint if its worn off.
Second option is to solder/fix a length of wire ( I've heard iron best don't quote me) to the two contacts in the phone and this make a new antenna. Use Xda search to find link.

I opened the cover, and I tried to raise the contacts a bit. it didn't help.
this happened when I flashed the new radio on the 12th or 13th. it was working before that. now I tried a few radios but none have helped.

I'm using AOKP latest ROM no problems with GPS or anything else, stable and great battery life. I also had very good results with ARHD 7.3. Back-up your ROM and flash AOKP or ARHD 7.3 and see if GPS works if not download GPS status from Play Store and see what it sees. If you still have problems then wind a bit of wire about 10 cm long around the 2 terminals on the phone behind the LED light and see if this helps with signal.

so I remove the cover, wind a piece of wire around each connector, and see if I get signal (with cover removed)?
btw, I tried the official cyanogenmod 7.2 nightly. same problem.

Yes wind wire around connectors, this is what I have read somewhere on this forum search it. But first flash Android Revolution HD 7.3 ( Cyanogenmod) and check GPS status it might work as this is Android 2.3.5.

http://forum.xda-developers.com/showthread.php?t=840040 says it overclocks the CPU. I don't want that.
anyway I am downloading it. 426MB so going to take a few hours.
I'll post results later today.
Edit: I downloaded it from work then installed it. same thing. it won't find any satellites.
I will try the wire thing later on today.
But I am really sure this is a radio thing as it worked till I flashed a new radio.

Did you flash the radio 12.65.60.29_26.14.04.28_M that ARHD 7.3 recommends?

No, HTC doesen't make them anymore, but you can still find one on some websites, and also you could find one made by someone else than HTC and being compatible, try on amazon.com

I can't make interational payments to buy anything from amazon here but I will look in local stores for old/spare parts

After having some issues with GPS myself i went on fixxing it.
I tried a new radio and solder the antenna contacts at the same time but it worked.
So i dont know wich one was the actual solution.

From what ive heared older radios wont work with GPS on ICS, this radio does and also some others.
