X1 - GPS does not work anymore

Hi all,
since today all of my gps-programs (smartrunner, terracrosser, on the road panel) i´m normally using (at last yesterday) do not find a gps-siganl anymore.
I´ve tried htc gps-tool, but it is saying "failed to send NMEA command"
In settings the internal gps is set to com4, harware (external) no com, managed by windows.
Any ideas, or is there a program to check if the gps-chip is generally ok?
Thanks and all the best.

Coincidentally, about 5 days ago I found that my GPS on my R1A ROM stopped functioning after exactly 2 minutes. Tomtom and all other GPS apps would get a fix normally, then crash the phone after 2 mins (Tomtom goes gray) and a soft-reset is needed to get the phone going again. I tried reinstalling most of the apps, but nothing seemed to help.
In the end, I took the gutsy way out, flashed my X1 to R3A (even though there's rumours that it's not the 'official' release), and everything has been good ever since.
I know it's not really a 'solution', but I sure as hell couldn't find the fix. I've had my Xperia since the November release with R1A, and it just did this to me about a week ago.
Anyways, happy with R3A having skipped R2A. Not HUGE benefits to upgrading, but definitely some positives.

Hi Scar,
flashing to R3A means that all programs and data will be deleted?
Isn´t there a way to reinstall the gps-driver, like at "big windows"?
How did you flashed? With SE Update Service?
I am a X1 User for about 7 weeks, so i do not had such issues until now and flashing would be my first time.
Any other ideas around?
Thanks and all the best

Hi mrx_bln,
Flashing to R3A will mean that your device data will be lost. If you use ActiveSync, then all of your Contacts/Appts/Tasks/etc. will get re-synced when you re-create the partnership after flashing. You also might want to search the forums for "PIM Backup" which will allow you to set a "Custom" backup to grab your files, as well as its ability to save Call Logs + SMS.
I flashed my ROM by using the microSD method, which is to place the (official) ROM in the root of the Storage Card, and have it named "kovsimg.nbh". You'll find more info from Jack Leung in the ROMs section of the Xperia X1 forum here.
As far as I know, there is no way to reinstall the GPS driver. If you have never got a signal though, and your symptoms aren't like mine were (I got a fix for 2 mins then it always froze after that), then you might want to leave it outside for 10 minutes to ensure that the GPS isn't working. Also, run QuickGPS to make sure you've got the latest data file.
Hopefully you can figure it out, as flashing is a bit of a pain to have to reinstall and reconfigure everything. The silver lining to that dark cloud is that you can ensure that the device is running mint.
Let us all know how you make out!

If your GPS crashes satnav apps after a couple of minutes, try deleting your 'extra.bin' file.
This is the QuickGPS download file which is likely to be the culprit, and you can always download another which is likely to be okay.

Hi all,
thanks again for your suggestions.
I´ve run "configuration - system - delete memory" (in german: Einstellungen - System - Speicher löschen) from the phone, which is a "hardreset", i guess.
And look, after that my GPS is working again.
The HTC-GPS-Tool is working and my favourite apps (Smartrunner, Terracrosser) have GPS-Signal.
So, my result is that is was definitely a sw-problem and i am wondering that there is no fix for this, because regarding to some threads it looks like that happens quite often. I mean, even the developers of htc gps tool should have the knowledge to write a fix, don´t they?
May here is a wm crack who has a look at what a hardreset is doing with the gps and writes a little tool to fix this manually?
Many other users would appreciate a lot, i guess.
Let´s have a look when the problem comes up again
Even the quickgps tool came up with an error (something like "can´t connect - try later"). Then i will try to delete the "extra.bin"
All the best

My GPS hasn't been working for about 2 weeks now. Not about to hard-reset, but would love to find a simpler solution.

Try this solution. That worked for me and many others It is way simpler than a hardreset

I have exactly the same problem after every ROM flash.
And always manage to fix it in 4 steps:
1. Erase GPS data using the HTC tool, wait 30 secs, all satellites should vanish
2. Cold start the GPS, wait 30 secs
3. Power down the phone, power back up
4. Start the HTC GPS tool again and wait approximately 2 minutes for the gps to fix. If you screwed up steps 1-3 then after starting the tool you will get a pattern of satellites. The screen must be clear and it should start looking for satellite 02 (searching for almanac)
Never had to cold start the phone- I suppose it does exactly the same as my four steps.
I was working with various GPS units before and the Diamond one is definitively the most fiddly of them all.
I suppose there is a bug in the COM4 GPS communication protocol, I have noticed that the stream of data often cannot be stopped by closing the connection with the GPS inside the tool.

Mine works again. Downloading new QuickGPS seemed to solve the problem.

i have the same problem with my gps since yesterday - could you please give the link, from where you got the quickGPS?

I thought QuickGPS came with the phone. Load up the program, then hit 'download' and soft-reset just in case.

Thx
I've tried it - so I think I have an other problem with GPS

Enough satellites but no fix

Hello all,
I am using Froyo XXJPO on my Galasy I9000. My problem is, that I cant get a GPS fix. But I can see 9 satellites if I use a GPS test tool.
Any idea what I can try? Thank you.

Well this is a first, someone having a gps problem.....you tried any of the million suggestions already posted?

While it's true that GPS problem has been discussed at lengths, people normally complain about poor accuracy and intermittent fix.
OP here is talking about another problem which I now experience myself since upgrading to Froyo. Quite often, SGS sees plenty satellites with SNR above 30, but just doesn't use them. At the same time and place my friend's Nexus sees less satellites but gets a fast and sure fix with them. This seems to be a driver problem in Froyo, not a hardware issue.
Edit: Forgot to mention that SGS usually gets the fix eventually, it just takes up to 15 minutes sometimes.

No fix issues have been done to death as well. Normally sorted by dicking around with your supl settings in the hidden menu.
Gps is just ****e on this thing, hope one of the solutions works for you.

Get GPS Status (from the market)
Reset and redownload A-Gps from the menu (menu, tools, Manage A-GPS State)
Retry and tell us how it goes

It was the first thing I tried as soon as this issue appeared.
Doesn't make much difference if any.
By the way, on Eclair GPS worked just great for me (with JM7, that is. Before JM7 it barely worked at all).

I got the exact same issue, I can see like 8-10 sattelites with plenty of +30db and can't get a fix. My TomTom gps from 3 years old only sees 4-5 but gets instant fix.
Before I was on JP2 and this didn't happen > it fixed fast and sees the same amount of sats.
However, I must say that accuracy is great, when I do get a fix, accuracy goes up to 16 feet within the minute ands stays that way.

can you look into the LBS settings and tell me what is the accuracy used?

In my first tool I have written something about "GPS test tool". This GPS test tool is GPS Status. If I download A GPS data again make no chenges. Just a lot of satellites wihtout fix.

Well, to both
LBS Menu: *#*#1472365#*#*
Standalone + "Hot Start" + Accuracy More than 15 + "Automatic" in SUPL settings.

Actually, it's now *#3214789650# (since Froyo or late Eclair ROMs)
I'm using accuracy 30 now. Was testing it with 50 some time ago with no noticeable difference.

Weird, and it was working before right?
Have you hard reseted the device prior and after the rom upgrade and cleared the caches?

when i try to access this LBS menu in froyo i hit the final * key then it all disappears and no menu pops up.....
What am i doing wrong?

Same problem here.
GPS was great and dead-on accurate on 2.1 (O2 UK official firmware) and now it rubbish (O2 official froyo).
This is not a hardware issue.

same problem here, just that there are no values in gps test (time is always 00:00 as well as all others and the compass is jumping back and forth.. the day before yesterday before i've had used faster fix it worked great =( ) anyone knows how to fix without reflashing?

Weird, I got the exact same firmware as a collegue and he gets a fix way faster than me, he even sees sats inside our officebuilding (I see none).
However, using the 3214789650 code and doing the Get Position test, he gets a weird orange text where I just get regular information.

This might be because of your colleague having sensors enabled for GPS

Nice!
Tried enabling this, and now I also see sats inside

GPS problem solved!

GPS problem solved!
Have had huge problems with my GPS and sought advice both here and other forums.
EVERYTHING has been tried, all possible combinations of room's, radios, and ril'files, fasterfix, gps status, fastreboot, delete cache Dalvik etc. I can not count all the times I've gone out on the porch and pointed my HD to the sky with new hope but no result. The best I have achieved is fix during the 5-10 minutes with an accuracy of about 140m .....
Then I found this http://www.youtube.com/watch?v=7qm_z65LA8k
Thank you knglaser
It seems that the GPS antenna sits in the flash cover!
I tried to press the flashcover and it worked just like an on and off switch for the GPS, satelites just fell in and in a matter of seconds I had the fix of 10 satellites This with an accuracy of 5-6m.
Picked out the blitz cover and "adjusted" the contacts between the cover and the phone and put it back in place, it took about 2 minutes.
After this operation GPS works perfectly
I am now happy since this has been incredibly annoying, I use GPS to both training and in the car and have not been to happy to send the phone back to repair since this usally takes long time.
Hope this can help others who are struggling with the same problem?

Thank you for this. At first i dismissed this as my gps problems only started immediately after the ota gb upgrade installed - it was then taking over 4 minutes to get a fix. However in desperation i took phone out of case - simply pressed the cover in the place shown in video (didn't even have to remove) and hey presto now get fix in seconds. Put phone back in case and all is still well.
Simple but yet very effective - thank you.
Not sure why the upgrade should have triggered this problem though?

Sadly, pushing the cover down is not working for me. Thanks for the video though. I will have to get some tools and pop the cover off to see if it looks like my contacts are no good as well.

apparently i solved my gps problem but not like above. i tried but didnt worked.So i install the new version of gps test, go to settings and then i push clear AGPS from top.then update agps.restart application and seems to work now. I will see. Pls tell me if you try like me and what is your experience
update: unfortunately the problem come back again...

GPS is not even locked while iphone did that within 3 sec

Dear users ,
as i told , i have a big problem with the GPS it take LOOOOOONG time to fix
i did google the problem thy advice to tried *#*#1472365#*#* and *#*#3214789650#*#* but nothing happens when i type the numbers
is it software or hardware ! and what is the fix

The answer is all over the forums. But some more information about your device would be helpfull. Ill assume that you are running a stock ROM. Many people have had great success fixing the GPS by flashing to XXKG6 firmware. That worked for me. Give it a go.

sometimes i can get a lock in 30 seconds and sometimes it take 5 mins and that`s with a clear sky, and i have tried must of the gps test apps with downloaded assistance data.

What version firmware version are you running? Do you have a custom ROM installed? Rooted? I to had the exact same issue with my phone. I was running the stock Bell ROM from Canada. Firmware was MUGKG2 standard on Bell/Virgin Phone. I rooted my phone with CF roots available for KG2 and had used all the GPS data tools that I could find. Then I flashed my phone with Cognition ROM which is using XXKG6 and BOOM GPS working. I found all this on this very forum. I will search and and post it for those who cant find it.

Get the GPS Status app and the Faster Fix app. Reset the A-state.
Set the server to your region. I got amazing results just from that.

Enable wireless networks to locate if you have data. Found me in less than 3 seconds. I suppose - that's what iphone does automatically.

In order to get the most help possible instead of saying not work, why don't you say what you tried to do, what happened when you tried, and then say it didn't work. That way you can get the most help as possible.

Update your firmware to a newer version.

I did install :
GPS Status app and the Faster Fix app.
point Faster Fix app to Asia.
restart the phone
open the "GPS Status" and open google maps !
still the locator blinking for more than 30 min !
Thank you

Try updating your firmware. As i stated I tried everything as well. It wasnt until I updated the firmware did I get consistant GPS connections.

Mine locks within 5 secs without any firmware change, a Galaxy S II right out of the box. Maybe you're in a place without much satellites or you're indoors? Or maybe there's a malfunction with your network an A-GPS.

Hi I had the same problem - GPS could see plenty of satellites but would not get a "fix".
I then rebooted the phone and then within a few sec it could get a fix even indoor.
So try to reboot.

But you forgot to say what firmware version you're using. Stock is not a version label.

Totally strange GPS behavior

Hi,
I have a totally strange behavior with my GPS. I'm using CM 13 right now and tried it with the official CM 12.1 and the stock ROM, all with the same behavior. Which I figured out so far is that the GPS need around 5 Minutes to get a lock. The only solution I found so far is using GPS Locker from the play store (https://play.google.com/store/apps/details?id=com.silentlexx.gpslock). With this app I'm able to get a lock within 10 seconds or faster. But I like my phone as clean as possible and so I want to fix the GPS without the need of an app. Hopefully someone of you could give me an advice how to fix that.
That are the solutions I tried already:
- Flash the stock ROM, wait until I get a GPS lock and flash a custom ROM
- Download several GPS Fix Apps to reset the agps data
- Modified the gps.conf file
- Open the device to check if the antenna cable is connected probably

Flash the stock ROM, wait until I get a GPS lock and flash a custom ROM
Does nothing as you have over written the system .
GPS is a kernel effect .
agps Patch from xda/derekgordon may be worth trying .

Thanks for your response. I got some time to give it a try but it didn't helped. It seems that Google maps doesn't work without an app that locks the GPS. Gps testing apps are working great only maps seems not able to find the right position by itself. Any other ideas someone?

fyi when I was on KitKat my gps locked quick and worked great. Since going to lollipop, I cannot use my gps as it constantly drops. So frustrating so I have tried other apps to see if I could clear the data/reset but none have worked. I was going to flash back to KitKat today but I am going to try GPS Locker as you have provided and see.. if not going back to 4.3...

ok so long update. What a PITA... I got back on KitKat 4.4.4 and gps seemed like it was a go.. but then died on my 65 mile drive to work. bout half way.
i was getting 15 satellites found and 3-6 in use...
so I got tired of the annoying.. hey upgrade now so went back to Lollipop. I then googled last night and found this..

WOAH!!!! just opened me phone up and viola. Unplugged. I just walked outside and BAM!!!! 21 satellites in view and locked on 18!!!! WOAH and in 3 seconds...
