Finally a GPS fix for SGS

after applying the attached zip through CWM the GPS is finally working!
instructions:
1. apply the fix through CWM
2. in LBSTestMode:
a. verify all values in the application test are default
b. in the SUPL put supl.google.com and change the port to 7276 with no secure socket
c. wipe GPS data
3. after the first fix (~3 minutes) you will get a fix instantly almost in any condition at any time
the fix was validated on 2 different vibrants with GPS issues
goodluck

He got this from the i9000 forums. I've personally used this, and it helps with the gps dramatically.

This is an old, well known pre-JI6 fix. DO NOT APPLY! This also NOT development related, try the General forum next time.

Hi all,
you can say what you want about this fix however, both I and BobLeponge23 have vibrant's phones with GPS issues.
we have tried all possible fixes:
JI6, JI2, JK2, JK6, samsung restore app, changing all the settings through LBSTestMode
nothing worked until we tried this fix.
The change is instant.
we have now a working GPS under:
the new axura 2.1 (JK6) and Obsidian_V5_beta (with modem JI6 installed).

Ok. Won't argue with that. Whatever works for ya!

Do you have "Use wireless network" unchecked? And WiFi off? With only "Use GPS Sat" checked? Cause that is the only way to see if your GPS is really fixed.

in LBS Test mode you wont get fix just with wireless networkor or WiFi.
in general when the GPS icon is flushing you dont have a satt. fix although
you might get general fix from the wireless network.

That's not a good test for phone GPS units. The phone's GPS uses network location to help get a faster fix. Apps like GPSTest, GPSStatus, and LBSTestMode won't report a GPS fix with only a network/wifi fix, so I don't understand the obsession with this sort of a test. All it will do is slow down your GPS locks.
Disabling wifi does make a difference on newer firmware (worked on JFD, but JI6 and up broke it). With wifi connected, the phone doesn't download the GPS data properly, so it acts like a standalone GPS and will take a long time to get the needed data from the GPS sats.
The GPS chips in our phones are NOT designed to get fast locks without assist data. Even the ones that are, sometimes take a while for the accuracy to really get good because of this data. That's why you should have a data plan for best results. The GPS needs data to calculate your position. It can get the data from the sat network, but that's SLOW. Getting it over the internet is many times faster, even over GPRS. That's one reason why it's irritating that wifi doesn't work with it. Those without data plans are basically screwed. GPSStatus seems to be able to get it over wifi, so you can try that. The data should be good for up to 24 hours.
I have no idea what this fix does, and I won't be installing it as I'm satisfied with the GPS performance post JI6 with my phone. Even with JFD, it worked fine once I set the supl settings up.

they are sharing a fix.

If this is working for folks where flashing Axura 2.1 didn't then, that's all that matters. Go for it. However as I'm running Axura 2.1, I have no need of this.
I just don't want people thinking this is the ultimate fix and breaking their phones trying it. I've seen it happen with simpler fixes.

I was using a jk2 rom also, and GPS would work at times, even in a large Metro area. i flashed this, and now I even get GPS locks inside of buildings where it would never lock before. I am happy. Indoors, it gets a lock in about 10 - 12 seconds, outdoors about 5 or less.

I don't understand how it can work, it uses jupiter.xml subsystem that TMO US Vibrant lacks

well fellas, i have so much dragons in the vibrant already i figure what could possably go wrong now lol. Running nero beta 3 and it actually works,got an instant lock on precisely where i was,dident had that before with all the other fixes,couldent believe it but yep works. Thanks for this fix

Didn't make a difference for me. Since JK2 ive always got a fix in under a minute. With this installed it was over a minute but under two minutes. I'll keep it for a day to side if anything changes and report back.

[Q] Froyo GPS Lock Problem

Ok...so after updating to Froyo my GPS is not working. Not only that, my phone can't seem to find my approximate location even after enabling "Use Wireless networks". I used GPS Status app from the market and I confirmed the phone was seeing several satellites, but it was getting no lock. I had no problem with my GPS with 2.1 aside from losing my location occasionally when I drive through the downtown.
Is anyone else experiencing this issue? I'm running my phone on Rogers network, unlocked and rooted.

You didn't say what version of Froyo you are running but I'd change my modem file and use one of the alternate ones that DocRambone has. There's a thread on this but I find the ZSJPE (Hong Kong) version to be superb (and our company develops an app for the phone that uses GPS for golfers) - very quick, very accurate...

Oh I'm using JK4 from Bell..and kernel version 2.6.32.9....
Edit: Oh and I have also done factory reset/cache wipe...and it's still doing that...I want to see if I can fix this without changing the modem file or anything like that...

I'm having the exact same problem since upgrading to the official 2.2 release from 2.1
EDIT: Bell Galaxy S Vibrant, Unlocked and running on Rogers. Not rooted.

Ok...so I'm a bit relieved to know I'm not the only one out there...From the things I've been reading it doesn't seem to affect phones running on Bell networks..but shouldn't GPS be not affected regardless of the network you're running on? I don't see why it's refusing to get a lock...

I can't believe no one else is having this problem, maybe we're the only ones unlocking??

I was also having this problem. I updated to bell froyo using kies, and am unlocked using rogers. I loaded gps test, set it so it wouldn't shut off the screen, and let it run for about 30 min in a window. Eventually it got solid lock on a couple sats and it now seems a lot snappier to get a lock.

Ok, good news! At least for me anyway... I decided to try keeping my GPS on and let my phone to try and find my location..however long it was going to take. I don't think it took me 30 minutes but it took me good 10 minutes before my GPS found my location. I think the problem was because I'm having trouble getting location information based on my wireless network and updating to Froyo and doing a factory reset must have deleted my satellite schedule. Right now I'm just so glad to find out my GPS isn't broken! :-D You should try the same thing I did.

Thanks Yeria, that sounds like the problem we're having.
I do find that if I give it enough time, It will get a pure GPS lock, but I'm not getting any aGPS (the network based)
That thread you link sounds like the solution, but unfortunately I can't seem to access the file they tell you to modify

I too have GPS problems right after upgrading to official froyo. And it kept getting worse when i tried custom ROM. I tried factory resetting and format all my sd card, cache wipe etc hoping that it will return to normal like when i was in 2.1 elcair but to no avail. I don't know if some bad code was left behind when i did the official upgrade through kies. All i can say is it was working fine when i was at 2.1 then suddenly went bad after 2.2.
By the way, my problem is my GPS lock kept of disconnecting every now and then thus rendering my GPS useless as it kept on displaying my location as "off road" even though i'm on a clear highway with clear and bright skies!

ahh, if I root the phone I can get to
/dbdata/databases/com.google.android.gsf/gservices.db
unfortunately, this phone doesn't have sqlite3 installed!! I need to try and find that
EDIT: Found a copy of sqlite3 and was able to push it to the phone. edited the db as people suggested! I'll have to test it on Monday

Based on what I have found so far, and assuming your aGPS or any other wireless based assistance features are not functioning properly, doing a reset and cache clear will not help with your GPS at all. I have read that the phone will try to download the satellite schedules directly from GPS satellites if you're using purely satellite based GPS option. It'll be slow so it will take longer to get a lock and that's why phone will use other means to shorten the lock time. Once the schedule is downloaded, they said there shouldn't be any problem until the schedule expires, at which point you will have to download the schedule again.
I think the reason you're losing lock frequently might be because your phone doesn't have a clear view of the sky..? I used my phone GPS to drive around Toronto, Vaughan and Mississauga last night for at least 4+ hours, and I did not have any problem.

So, I tested today after updating the db.... no agps still..
Anyone else still.having issues with agps?
GPS works, just no agps since 2.2

This is why I unfortunately have to use an old Tom Tom GPS!

i'm having this problem too. i finally got it picking up quickly on 2.1 but once i updated i haven't been able to ever get a solid lock. has anyone found a solution yet??

Now that my wireless location service is kind of working I thought aGPS should also naturally work but I guess not... My GPS takes a pretty long time to start up and I haven't found any fix for this..
It's funny because I didn't really have any problem with my GPS with 2.1 but now I do with 2.2...

GPS Related Files

Hello:
I need a list with all the gps related files.
I'm triying to make a CWM update with the JI6 gps files.
The reason I'm triying to do this its because JI6 was the only rom at the moment wich gave me acceptable GPS.
Thanks in advance.
Whipon.
EDIT: I forgot to mention, I have a rev 1006 Captivate.
Usually I see from 6 to 8 sats, but never get a lock.
I've tried several roms (rogers froyo, JPY, WSJ3, Adromeda) with the same results.
I can't get a lock.
With JI6 I got a lock in seconds.

gps is funny and i think the files you are reffering to are the same on several roms since ji6. actually ji6 would crash the gps daemon on my phone if i changed the lbs test settings. and as far as i can find ji6 jj4 and jm9 and many other i9000 roms all have the same libraries. whatever the other differences may be it might be hard to find the files and they might not work on x rom
if i where you id try the gps restore app. i can tell you it doesnt do what the description suggests because i have used it and it doesnt set lbs settings to stock. my lbs changes remain after i run the app. also it clears gps data that lbs test mode doesn't. a gsm reset or factory reset can fix some gps problem if the problem is in data. the gps restore app seems to have a similar effect but you dont need to backup your apps to use it like a factory reset. if it doesnt work youve wasted 2 minutes to install and run it.
read da_g's first post in his thread and then read it again. try all of his fixes and make sure the lbs settings match the config and jupiter files for each fix. i find that the control plane version works the best for me.
also have you tried the ji6 modem on those roms? the modem is critical. some modems get better reception and may also pickup more noise. you may need to attenuate the signal, noise may be preventing a fix, the signal can be attenuated in jupiter.xml. or you may need a stronger signal, maybe ji6 modem is giving you better reception.

Well, it seems it worked
Well, I'm editing the post, because it worked.
Changed all settings in LbsTestMode to the default Darky ones.
Cleared gps data.
Then loaded Gps Restore and it successfully completed all tasks.
Got a gps lock in seconds with 25 meters accuracy.
Its far better than nothing.
Thank you very much for your help .

Its not working well
Well, tried the gps with LbsTestMode and I get a lock as I said with 25 meters accuracy.
However Ndrive can't give me my current position. It shows me in at least 100 meters from I really am, in some random street.
Google Maps has a 1500 meters accuracy.
All is left is tweaking jupiter.xml.
I don't want to use JI6 modem because it doesn't support HSDPA.
Currently I'm using JK4.

It seems its fixed
Well, did some tweaks to jupiter.xml and after a reboot I got a lock in around 5 seconds with a 10 meters accuracy.
I noticed my jupiter.xml had the spirent supl server instead of the google one.
All tests were done in my house. I have to test it tomorrow in the street.
I will post my results tomorrow ^^.

[Q] My GPS hasn't worked since updating to 2.2 - help! - RESOLVED

Hi,
I got a Samsung Galaxy S here in Australia, rooted it and upgraded from 2.1 to 2.2 I know that GPS worked just fine with 2.1, I was able to walk home and see my position updating very nicely on Google maps
Since updating to 2.2, GPS hasn't worked at all. When I turn it on, and start an application that uses GPS (Navigation, Maps, etc), the GPS icon sits there and flashes back and forth between those two types of icons and I don't get anything on the maps which shows me where I am. I haven't chased this up since upgrading, but it's starting to bug me now
After searching these forums for 'gps not working', I've pulled down the 'GPS test' application and I don't know for sure, but it appears to find one satellite:
PRN SNR Elev Azim Flags
2 11.0 74.0 150.0
But the GPS icon just sits there flashing back and forth.
I may have missed something since upgrading, do I need to do something to the phone to get my GPS working again?
Thanks!

OK, I seem to have fixed the problem I turned on "Use wireless networks" and voila! I now have successful GPS lock and position in my maps
I would have thought that you could use GPS without having "Use wireless networks" turned on!?

Wouldn't call it a successful GPS lock. Since you got it with the mobile networks. (in my case when I use it . the accuracy in my village is about 1000-1500m since the BTS is that much far from me )
So if you get into an area with weak mobile networks, wont help you much .
Wouldnt call this as resolved with "BAD GPS" cuz your GPS still sucks as before (and doesnt work , you just found a workaround that was there also before , 2.2.1 has even some other function for GPS that tries to fix it (or help?) )
But since you can use it now, its ok I guess . OH and there are kinda almost no real fixes for this. Most of SGS GPS suck . There is GPS aids, shutting down wifi, GPS status app, changing the something according to your country.

Ok!
I got the same problem as the user from the post.
GPS worked like a charm on my Galaxy S (NDrive or Google) running 2.1.
I updated it to Froyo 2.2.1 JS7 and since then it doesn`t work anymore.
I can't get a fix.
I did the GPS position test and It locks on 8 satelites. Why the F%CK it doesn`t work anymore?
I am almost going back to Eclair.
Any sugestions?
TY!

So you get a lock when doing the GPS test, but no luck in any other applications? I couldn't get a lock at all until I turned on my wireless as well as the GPS, then it worked for GPS test as well as applications...

I get a lock on 8 satelites on the Location Test with and without "Use Wireless connections".
BUT
I can't get a lock when I am using Google maps, with or without "Use Wireless connections".
I bought the AIDS GPS app on Market, but it did't work neither.

Galaxy S GPS Can't find satelites

I Deffinitly Tried everything, I tried the hardware fix, Change The Pool To Israel, France, Europe, everywhere, I tried the gps doctors , nothing works..
I just can't find any satelites, in the gps aid app when i press the GPS doctor it's telling me that the gps status is off.. is there anything that I didn't try and could work?
Please, I'm Desprit..
I Tried and the problem is at every rom
I'm Right now using ICS RC3.1 By onecosmic..

try gps status , to see if is an app error from navigator and other gps programs or RC3.1 probleme , and if are ICS probleme try first to flash devil led kernel
and a wipe cache

I though onecosmic's RC 3.X was only for the i9000 and not i9001.

Well I Tried and looked at the gps status, I didn't really get what am i sepoused to do there, I reset and cleared all gps data and downloaded it after wards..
the app didn't show any errors ..

Try to get GPS Aids from market. Had the same problem and that fixed my gps

Tried the gps aids too... Ain't working.. anything else?...
When I tried the gps doctor at gps aids, it showed me that the gps mode status is not working (the cube near it is red) and after trying the setup and the fix everything possibility it still ain't working... any idea?

Try to download the GPS test and install it, then go to settings and select clear agps, then update agps.
Oh and dont try the gps inside your house! Try it in the middle of the street! Gps signal is always reeeally weak or undetectable inside a house.

Unhappy to say, still didn't work!

Can you post the exact ROM and kernel version you are using?
Also try the following. Disable wifi, reboot phone, try GPS test.
I had GPS problems a while ago and the workaround was to boot the phone with wifi disabled. Something todo with init scripts messing up GPS/BT.
When in Google maps do you get the GPS icon in the status bar when trying to GPS fix?

try this http://www.youtube.com/watch?v=STlb...xt=C3c039cbUDOEgsToPDskJOGd0pTyqyB6SPWL6OcwDB

Better to just send it back to samsung for them to fix if it's under warranty. If not, just sell it and get another one. I really like my SGS but i've given up hope for gps. I've just accepted it doesn't work and be happy the phone's great in everything else (like sound). Was kind of gutted having paid so much for a phone with a non-working gps but to be honest i have little need for a gps so when i need one i just use a dedicated one.

Now I'm using RC4.2 ICS By Onecosmic, Gps Still aint working well, I do get the gps icon... but still, my location ain't really accurate and I cant navigate or anything..
I tried the video that have been posted, None improvment...
Is there any thing else?..

The GPS issue with the i9000 is a mystery to me. I've tried software and hardware fixes to no avail with GB based ROMs. However, when I switched to Slim's ICS ROM my device started to register satelites again with the GPS test app from the market. Despite this when I open the maps app it takes forever to get a fix, so long infact that I give up long before it ever does

Same issue AOKP Milestone 4 ICS. Nothing on GPS Status.

I use market app GPS aid.
