Thanx pdajoy,

I used the last two hours trying your trick, but unfortunately without any results. Not a single peak movement....

I went up at around 2100 meters to have around 220° of sight, again, Diamond (QuickQPS data already expired) found in less than 1 Minute his fix and Athena (QGPS actual for 2 days) showed not one single reaction except to the satellite numbers. I compared them to my Diamond and it was 50:50. eg 27, 17, 9 etc. were same on both but others were different.

My present life of suffering was in ROMs:

AP3 -> AthenaUnlocker v3 (crashed, but restored after reflash) -> AP3 -> R 1.58 -> EnableRapi.cab -> AP4 -> Irus Vanilla 3.5 -> MichyPrima 5.1 -> Irus Full 3.5 -> AP4 -> AP3newslp -> SPL1.2Olipro -> AP3 -> HTC Stock German(latest from Website) -> R 1.57 -> R 1.58 -> T-Mobile Stock German (2.35.111.3) -> HTC Stock -> AP4 -> R 1.58

and in programs:

ceManager

NoniGPSPlot

TomTom7

VisualGPSce

GPSTester

Meanwhile I started counting hardresets but forgot to continue somewhere at 43. I love WM 6.1 ROMs much more now, no nasty softreset after software installation...

First I tried it by radio changements, followed by better software (NMEA reset...), different ROMs and tons of equal problems at google and several pages here. Isn't there any special radio I could flash, some mtty hex changing or any registry key?

Thanx!
[Advantage X7500, MDA Ameo ROM Development] pdajoy:
NODeeJay, sorry to know it didn't work out.

On my crazzy Athena, fix established only with at least 4 solid satellite numbers.

If you are getting almost similar like the Diamond, my bet is the gps in Athena is fine.

I'm using GPSProxy 2.2, http://sourceforge.net/projects/gpsproxy/ fix time varies with

different baud rate setting but definitely get fixed, with any cooked rom here.

You may need to re-try and confirm the gps status without any other

program installed. Just the gps software.
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
I remembered the Athena's GPS was not the best and fastest, but even in the old part of Pragues with very small roads I got a fix. At last I got one satellite with more than 0 singal.

OK, to understand you right without any other software:

HR -> AutoInstall -> EnableRapi.cab -> AP4 -> HR -> SR instead of AutoInstall -> .NET CF 3.5 -> SR -> GPSProxy -> GPSProxy options (Com Port, Garmin etc.) -> Start?

So my progress:

have done it like the above mentioned way, after GPSProxy install I set the VirtualComPorts to COM8 and COM9 then I mirror COM5 to COM8

then I press Start and wait.

After more than half an hour I have still:

I had a look at the Log:

Informations but no coordinates...

I should play with the baud rate on both sides now? hardwareport - baudrate - GPS Proxy - baudrate - softwareport

Another question: GPSProxy is nothing else than the build in "port proxy" aka "external GPS"?

Thanx in advantage pdajoy, really, I appreciate your help very much!
[Advantage X7500, MDA Ameo ROM Development] djcedric:
i have exact the same problem on my athena!search all posts here,never solve this:confused:

my only way is to use bt antenna.
[Advantage X7500, MDA Ameo ROM Development] pdajoy:
Here is my setting for my Athena and GPSProxy.

Athena

- Program port: com8

- hardware port: com5,115200

GPSProxy

- GPS com port: com5, 9600 (set other value to try)

- Output com port: com8, 9600 (must follow com5 value)

Note: Do not tick Mirror GPS Input to Output Port

Back to Main menu - select Virtual COM Ports

tap once to Add, Virtual com port,

it automatically assign Com1, then exit.

If you use Garmin Que, then proceed to set virtual com port baud rate.

Select Garmin Protocol Output, Configure,

Port Type: Com Port

Com Port: Com1: (GPSProxy Virtual Com...)

Baud rate: 9600 (follow com5 value)

If not, just hit Start, first time run, fix will takes a little longer.

GPSProxy is nothing else than the build in "port proxy" aka "external GPS"?

Yes, it is, I use it simply because Garmin Que can't works with the Athena external GPS.
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
So it means our GPS lost most of their capabilities of reception and I'll have to use an external BT GPS from now on?

You have the same behaviour? Orange LED blinking while GPS is active, satellites in view but no one in use - not any reception at all

Followed the way exactly step-by-step and here are the results are:

Sorry, still no improvement, no reaction, nothing.

Even the other threads had sporadically resolved gps issues but not at all and only workarounds for specific reactions like (Urgent GPS Help)http://xdaforums.com/showthread.php?t=308606 and (Need help on GPS and SIRF/NMEA modes!)http://xdaforums.com/showthread.php?t=314422 etc...

I wrote a mail to HTC support now, let's see what they say.

Thanx for your ideas!
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
GPS no fix issue

Of course u have tried different ROMs, different radios, several HR's etc? In your case it was caused by what? ROM Upgrade, installed or deinstalled software, change from NMEA to SIRF?

I was so concentrated while my flashing procedure on running QGPS in german with realVGA and storing one year gps data with it that I cannot say exactly at what step it happened.

Conclusion for the "GPS no fix issue" till now:

The issue is ROM and radio independent.

The issue is also GPS software independent.

The issue could sometimes be solved by changing the gpsid_HTC.dll in \windows.

The issue could sometimes be solved by changing the COM ports and/or baudrate.

Sometimes it was solved by a (let's say) special numbers of hard/softresets.

Sometimes it was gone away without any interaction.

Anything I forgot or I am wrong?

Ok, we have to find out the reason for this issue I think. When we know who is our enemy perhaps we find a way to smash 'em out...

Who else can report the same behaviour?

Orange LED blinking while GPS use, satellites but no fix at all.

Are this satellite numbers correct, or are they some skeletons of old infos (perhaps stored in the chip or whatever...). I tried it several times, HR -> Autoinstall -> VisualGPSce explicit without any QuickQPS sync before and within seconds the Athe100 had 12 - 18 (even this count is different each test) satellites in view.

I'll take a walk now with my cats, another GPS try - let's see, I'll report.

Thanxs in advantage!
[Advantage X7500, MDA Ameo ROM Development] djcedric:
yes i have tryed many roms,radio roms,gps softs,settings....the orange led is blinking and i receive gps sattelites numbers and positions bud no data.exept 2times it was working quickly with lock!i never understand it,just a test outside my house and miracle it was working with com 4 program,none hardware baud 4800 and acces auto.the same day with no changes few hours later i retest and not working again:confused::confused::confused:

tryed to reflash and reflash again,never worked again!i have post here bud no one can help me and i dont find any solution!I buy bt antenna:mad:

im sure it is not broken bud cant find any solution.

i follow your post and really hope you can find a solution

Athena Programs port com8, Hardware port com5/115200 (always)

Warm start, during this screen capture, get fix not more than 10secs.

GPSProxy gps com baud rate range tested 9600, 14400,19200,38400,115200.

After many many hours to find which rom, gps software, various settings since I own Athena,

I finally settled with this gps program and still perfect with AP3 rom.

Never update the gps data, actually not neccessary.

From cold start, usually fix in around 45secs.

Some other gps programs I tried don't even show present of satellites.

Its still a major mystery to me why some works and some don't.

Believe others may had encountered strange result too.

GPS enable device shouldn't be so picky, there must be some undisclosed

hardware issues. Anyway, this piece of things is already obsolete to HTC.
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
Contact with HTC

Solution finders,

The last days:

I continued playing around with GPS measurements and the sat numbers do not change any more. I used different programs so I thought they were changing, but it’s the program reporting sat number X on different places.

After going back to the phone's absolute first state (ROM Original German HTC, SPL 1.10.0000) yesterday night I was completely bored and decided to call HTC, because my e-mail was answered with slipslop.

Apart that all support members think u are the stupid user (have u tried on COM4 and with TomTom; GPS needs to have a clear view to sky; my GPS first shows me some grey rows and then get’s a fix……. More slipslop) and HTC's opinion on xda-developers because the guys here do HTC's job most of the time much faster and much better we came closer.

After I sent her the photos of my last actions (sat but no fix with GPSProxy, VGPSce and the Diamond picture working) and approximately 40 minutes phone call she decided finally to send it back to repairs.

But the most important thing is:

Susan said that this problem is not listed in HTC's problem database for Athena and derivates. She said we need more X75xx users then we can escalate the problem.

To bundle power I would act as a single point of contact or you (with your “GPS no fix issue” not solved yet) contact HTC directly with my ticket# 081029UK15215473 and/or SN: HT735FM00623

Perhaps some MOD can make this sticky that we can attract more affected users…

Off-topic: Her GPS had the same problem, she reported, but by changing the location from UK to Germany it worked again.

Sorry, it is not purpose of the product to move more than 400 km to get signal again, GPS is global and that is where we want to use them! Else, GPS is integrated; external GPS is not the issue/solution here!

Tomorrow I’ll send them my Athena and report asab.

Thanx for all your help here, but I don’t wanna stop now. Every X75xx user with the same problem please report here with SN, ROM and Radio so I can contact HTC again.
[Advantage X7500, MDA Ameo ROM Development] pdajoy:
NODeeJay thanks for your amusing report from HTC, hahaha

Sorry to knoe yours was that bad. Hope they do a sat fix check before returning. Looks like the reciever working (from your previous post) but unfortunately output to program seems screwed. :(
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
Hey pdajoy,

**** happens. That's life.... meanwhile I'm so sad to use my Touch Pro instead of Athena LOL

Had a look into the service manual because my last hope was this antenna, but it ist all on one plastic mount so if GPS is not connected BT, WiFi and the rest wouldn't work either.

Off-topic: had another very nice talk to german Telekom this day cause my Daddy's modem screwed up. I can't understand who is doing their entrance tests there??? Most Hotline call times I am shure the guy behind the phone can be exchanged by other intelligent animals like for example monks or dolphin.

More than ten years I'm in IT now and I had several things like broken coffe cup holders(CD Tray) or not working DVD (inserted in the 5 1/4'' floppy and closed!) or simply people asking how to call my number from outside evertime the leave the country. Is all this stuff really so complicated or are we just more....

Annyway,

there are only 2 of this whole world of Hotline numbers I really like to call, the others I use to leave al my anger on a bad day: Of course number one is DELL support (specially with a 5 years contract NBD) and the second winner ist MS Partner Hotline. Never felt so powdered, showered, styled, hugged and relaxed than after calls with MS Partern or DELL.

Look, we had one and a half conversation and it was clear what is the problem and you sent me several great tips and ideas. You weren't asking stupid questions or stumbling around after I used the word "ROM flashing" - whooo techie. Our conversation in real-time wouln't be more than 2 minutes. What the hell I have to talk to a support line alwas more than 20 minutes and in 35% the problem isn't solved yet.

Ok, we are loosing the plot, sorry.

I will report asab (as soon as back LOL), I hope others with the same Athena/Ameo issue will report and I will take care that we find a solution with HTC.

Thanx again for beeing there!

They've never heard of this before? C'mon, I called them a year ago (US support, I would hope they share notes across the pond!).

Grrr.
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
Hey man,

was it solved? By what? If repairs, can u give me your SN or old ticket# please than I call them tomorrow and overgive (only prophylactically) it to my laywer, just for the case we have to go as far as http://www.htcclassaction.org/ because the HTC support is becoming worse each day.

Thanx!
[Advantage X7500, MDA Ameo ROM Development] techntrek:
My problem is that it would rarely lock and often took many minutes to do so (even with QuickGPS updated). When I called they were no help, only telling me the proper settings for External GPS - which I already had. Not sure if this is the exact problem you have since you can never get a lock.

Since then I've upgraded the radio and OS and after playing with the settings I can now often get a lock within a minute. If I'm outside. Usually only if I open more than one GPS program at a time (Google Maps can sit for minutes w/o a lock but the second I open Visual GPSce it will lock... WTF?! I assume there is a problem with the intermediary software/driver, like you do) Then there are still the random times when it won't work no matter what I do.

Sorry, don't have any reference numbers for you.
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
That's different (I think) because a) you finally get a FIX and b) (again I only think) when you start your application indoor where u are sure not to see any sat after 2 - 5mins u don't see any SAT (and I do)...

Right?

THX!

How to exchange or rename the original gpsid_HTC.dll?

Hello jsp91470,

I'm a newbie here and I'd like to try out to fix the fix GPS Intermediate driver by replacing the gpsid_HTC.dll as described in your first post.

Everytime I try to rename or overwrite the original gpsid_HTC.dll I get an access denied message.

I tried a SafeMode boot using monocube's utility but same result.

What steps are necessary to first rename the file and then copy the file from the other rom?

Thanks for your reply!
[Advantage X7500, MDA Ameo ROM Development] techntrek:
Have you tried copying the file using Total Commander, or the built-in File Explorer? File Explorer usually won't let you replace system files.
[Advantage X7500, MDA Ameo ROM Development] NODeeJay:
Close ALL GPS apps and try it with TotalCommander or RescoExplorer.

If not working you have to put into the rom...
[Advantage X7500, MDA Ameo ROM Development] AE:
Exactly the same situation. GPS is on and sending NMEA data with 12 satelites available but no satelite signals at all.

No luck with any software (including factory reset playing with sirf-tech 2.21)

This could be a hardware problem I'm afraid... No external GPS antena around unfortunately to check if it is just a built-in antena fault

Quite boring :(
[Advantage X7500, MDA Ameo ROM Development] AE:
Resolved

"Electronics is a study of weak contacts" :)

So, the problem in my case was in weak buit-in GPS antena contacts.

What I've done:

- completely disassemble Athena. Probably it is not needed - try to open plastic top of the athena case first.

Search http://www.mikechannon.net/ for dismaunting guides.

- take off the GSM module

- clean up and unbend all antenas contacts

- assemble antena (without GSM module)

- turn it on and found that GPS works again (FINALLY!)

- disassemble Athena again and restore as it should be :)

Now I'm happy with GPS working again :)

P.S.: There is a small chance that problem disappeared due to turning device on without GSM module but I'm not believe this...
[Advantage X7500, MDA Ameo ROM Development] techntrek:
I have always believed it was due to some hardware issue. At least it may only be due to faulty assembly (correctable) and not a bad GPS chip (difficult to correct).
[Advantage X7500, MDA Ameo ROM Development] vqscorpions:
when i got the x7501 with the original ROM, it works well with TT7, and it shown the best job in order to compare with HTC Kaiser (I stay in my house and it still received the signal very fast but HTC Kaiser did not work like that).

However, since I update to another ROM (even if it is 1.2 or 3.5 SPL rom, most of the rom in this forum and all 1.57 and 1.58 radio), GPS doesnt work anymore.

It only say: waiting for valid signal.... forever.

I tried all the ways that u discussed in this thread, but failed.

I think that, may be I had to come back to Original ROM.

Do u have any ideas

Why MODs dont care about this problem? :confused:
[Advantage X7500, MDA Ameo ROM Development] AE:
The phrase "TT7 waiting for valid signal" means nothing, sorry. This could be caused by different reasons and not only the problem described above.

Did you tried any GPS utility showing NMEA output on hardware GPS port (COM5:, 4800) directly? If hardware port is Ok - did this utility shows GPS activity when you set it to software GPS port (check the Settings -> System -> External GPS sure all settings are correct) ?

Actually I've never experience a problem with any ROM using software accessing NMEA protocol (not GPS API). There is nothing to work incorrect really...

thanks friend

but I wonder that , are u using TT7 in your athena?

I got the software GPS as u shown, and I installed it. It turned on and say: Seek 12 (i guess that it says 12 statelites).

But when I open TT7, it still waiting for valid signal... forever.

Could u show me what GPS software that u r using.

Even if now I downgrade to Official ROM, it doesn't run TT7 again.So strange for me.

May be I need to spend more time to explore this one.
[Advantage X7500, MDA Ameo ROM Development] cktlcmd:
I have an X7510 and I am using TomTom 7 version 910.9185 and iGO 8.

I have no idea why it works for me. One thing I notice prior to installing GPS Toggle, for iGO 8 and TomTom 7 to work immediately, I need to open another application that uses GPS such as WiFiFiFum or Google Maps for my Navigation softwares to work.

Installing GPS Toggle and turning it ON first prior to opening either TomTom 7 and iGO 8 makes the Satellite signal lock faster in my case. I don't know why it does not work for you. Sorry.
[Advantage X7500, MDA Ameo ROM Development] vqscorpions:

the difference here may be yr athena is 7510, mine is 7501.

however, i will try your way.

but in the past, i don't need to use a third software to use TT7, it worked well alone.

The problem only happened when I changed to another ROM.

Do you have the right GPS Settings in TomTom 7???

You need to configure the GPS Settings to OTHER NMEA GPS you shoud NEVER select BUILT-IN GPS, otherwise TomTom 7 won't work. Select the Baud rate and com port you specified from External GPS Settings.
[Advantage X7500, MDA Ameo ROM Development] vqscorpions:
it is so strange that when I got the phone first time, i installed TT7 and did not care about COM port, I also chose Built in GPS, and it worked like a champ indoor.

But the problem only happened when I update ROM.

and now, I am sufferring with UP ROM and finding the way to fix GPS.

I decide to keep AP 4 Platinium and looking for the method to fix GPS and Wifi. hic.

However, AP 4.0 is really good overall.

Only one stuck in sometime (i don't know why)

But with the original ROM, it usually stuck and I had to reset.

GPS is working now like a rabbit. thanks friends!

(sorry mod, I also post this message at another thread, but I need to post it here also to say thanks and notice about my situation):D

Hi friends

Firstly, so thanks to all of my new friends, who were trying to reply and show me the way to solve the problems.

Secondly, I want to give u the good news. Now GPS is working as a champ.

But it is a little bit difference with some guides from u.

- I follow the steps above and change the baudrate to 9600, but after reset, it comes back to 4800 as default.

- The COMPORT for program is COM 4. For the hardware, I set default is NONE.

- Then, I install VisualGPS.BeeLineGPS.v1.83.Build.125 and reset. After that I run Visual GPS Beeline first, it works after 20 seconds and lock my location when I stay in my car (The weather now is -1 celcius degree outside - very cold).

- Then I run TOMTOM, I choose BUILT IN GPS (but not other NMEA). And TOMTOM works perfectly after 10 seconds - I did that because I remember that I always chose BUILT IN GPS when I used TT7 with this one two weeks ago.

And here are some tests after that:

- I turn on Wifi, open DATA connection (that is a issue when I use Kaiser, if Data connection is opening, TT7 can not receive the signal), then open TT7 (without openning the VISUAL GPS), it works after 12 seconds.

- I come into my room (the second floor in a three floors house) and turn on TT7 without using any other software, it lock after 10 seconds with average 5-8 sats.

WOW. It can't be better.

But I still don't know which one help which one. Because, when I installed TT7, then I run it for the first time yesterday, it said: could not run because of the memory available.

Then I try to run GoogleMap (even if I did not connect to Wifi - so ofcourse GoogleMap only turned on but did not run with data), then I tried to open TT7 again and it run (confuse here, who can explain to me)

The problem only now is.... WIFI. I hope can fix it soon as the instructions from CMONEX.

Thanks friends.:D:D

ref post 51

in our case i the gps data is comming in so hardware is ok

1. data comming in could be garbage

2. gps has kept the last set of satelites and is stuck- thats why your row of satelites is identical to mine

3. sometimes turning the pda off while the gps software, like tomtom, igo, etc, is active i.e. the gps is workink and receiving data, could lead to problem 2.
