My GPS stopped doing accurate readings when i flash roms with the ziggy gps fix. the only way that it gets accurate(within 20m) is with wifi on and connected, if its off it says accurate within 3700m. Thats not too accurate if i might say, anyone else having this problem/ found a fix for it?

I've done that, and it knocks my gps off completely. Any clue why its attached to Google location services?

Interesting, I attempted the same thing and I am unable to get a lock when I disable the Google Location Services.
I'm running on Das BAMF 1.3.2 with the kernel update 3a which includes gps fix/enhancement from Ziggy.
I've been testing how quick I get locks when using the Navigation and I am still seeing a considerable amount of time before it finds a GPS signal. I've also used GPS Status from the Market to reset and download GPS data but I haven't really seen a difference.

Used this method and Ziggy's GPS mod and I get a lock within seconds as opposed to 10 minutes. If I turn on Google Services it goes back to a 10 minute lock time so I think it has more to do w/ the Google Services rather than modifying the GPS Config through Root Explorer.
Edit: I will add that initially my phone will say "GPS Location is Currently Unavailable" and 2 seconds later it gets the GPS lock /shrug
Well mine stays searching when the Google location is off, never gets a signal. What is the stock gps server so I can switch it back?

Well I just found that as long as WiFi is toggled on, the gps will lock on no matter if there's a connection or not. Tied into he WiFi somehow?

That is odd that WiFi affects the GPS locking. I'm trying to find anything I can on this. "Searching for GPS..." in Navigation is annoying as heck.
I also had a sneaking suspicion that toggling wifi on and off caused gps lock issues, I was using another rom at the time, but for some reason, all of those problems ceased when I flashed TeslaCoil and completed the gps conf fix.
Not withstanding, gps should lock quickly using only stand alone, and right now, my gps works splendidly

Where can I find that gps conf fix at? I wanna give that a shot.

You can grab it here:
Improve GPS lock - credit Ziggy471
It edits the gps.conf so the NTP_SERVER=us.pool.ntp.org
That comes default on the roms I use tho. Still attached to WiFi switch. What's the closest lock you can get with your gps?

i was having GPS issues with the last two bamf kernels. google maps seemed to lock onto my location after a few seconds or a minute, but other apps that tried to use the GPS would never lock on. i noticed when you go into google mapls, the GPS icon/animation appears on the status bar.
the GPS icon would never appear for other apps that tried to use GPS when using the bamf kernels.
with the stock TB kernel, all is well.
Ok, gps is definitely tied in to WiFi. Without WiFi on its 3400m away and with it on is within 20-50m. That only happened with the ziggy fix so maybe if anyone could show me the original settings for the stock gps server file I could change back and forth and test what the problem is.

So I rewrote the gps.conf back to the original north-america setting and that fixed the problem. Any clue why ziggys rewrite of a word in that setting would mess it up so much? And how is it ppl are supposedly getting improvements with that, like what exactly?

I don't know what the rhyme or reason would be for this gps issue, because it's so random, there is no pattern to this mess:
1. Got the phone, gps worked great.
2. Rooted phone, still worked great.
3. Flashed first rom, Virus to be exact, still worked great.
4. Several days later, with no rhyme or reason, I noticed that Cardio Trainer had not picked up location
5. Factory reset, problem still persisted, could not lock on to any birds, confirmed with gps test app.
6. Flashed CWR of stock rom post root, still not working.
7. Flashed RUU stock from fastboot, working again perfectly.
8. Have flashed 2 non stock roms since, BAMF 1.3.1 and first TeslaCoil (current) and gps still working perfectly
I can't think of what could have possibly caused this, but now that gps has been stable for about one week and I haven't been using wifi, over the weekend I'm going to toggle between wifi and 3g and see if it causes any issues.

I'll be trying the new Das BAMF 1.4 to see how it behaves. Wish me luck!

Joanni, I'm having the exact same issue that you've been having. With Google services on, I get the wide area. If I turn it off, I get nothing. The only way I get a lock is with WiFi on. I'm currently running Virus ROM.
I know enough to be dangerous when it comes to digging into my phone. I generally just follow well polished instructions. How would one go about trying your fix?

Joanni just edited the gps.conf file to read NTP_SERVER=north-america.pool.ntp.org
That was the original setting. It has been said that changing the setting to us.pool.ntp.org has fixed peoples GPS locking issues but in my testing I found no benefit either way. What I have found, is that turning WiFi on will enable the GPS to have better accuracy in finding your location (20 meters to 50 meters in my case). This is exactly what the popup says, the first time you launch Google Maps.
If you wanted to check what your gps.conf file has set as the server, you can use Root Explorer and browse to /etc/gps.conf
There is also an app in the Market called FasterFix that will change the server to north-america.pool.ntp.org for you.
Hey everyone
i'm pretty new to the whole nexus s scene, as i've had this device for about a week now. I've rooted my phone successfully and i'm running MIUI's latest ROM..1.8.5 i believe. Now for the problem..
For some odd reason I'm unable to connect to my 3G network at all (yes, data is enabled in the settings, and set to 3g prefered/2g/only 3g..still nothing). Usually there'd be that green "3G" on top bar of my screen, but it doesn't show up. Now i rely on wifi to go online, which isnt a problem...but it feels like my money's being cheated if i dont use my data in occasional situations. I've tried flashing it again and again, but no results. I've flashed my phone to the Oxygen ROM, and the little 3G icon appeared, indicating that data is enabled (i forgot to actually check if it worked LOL). I haven't found anyone else experiencing this problem with MIUI, but i've found threads on them having some sort of difficulty with their data. If anyone could help me out, or direct me to a thread that has a possible solution, i would really appreciate it ~ thank you in advance.
Also, I'm on Fido.....if that helps.
I'm on the latest miui and I don't have that issue try toggling the airline mode to see if it will kick it in. If not really download the Tom and do a clean install see if that works.

hey, i've tried toggling the airline and it doesn't help. also, what do you mean by "the Tom"?
What happens when you try to connect with just 3G (what type of error do you receive)? Miui's stock 3G icon is white
Also, I think the other gentleman meant to spell ROM

He meant rom, auto correct changes the word rom, I think you need to wipe and reflash the rom.
hey, i've just tried reflashing the rom...and still no 3g ): !
also, when i enable data, and set it to 3g..there's no error. there's simply no "3g" icon on the top, and i can't connect.
Did u try manually inputting your apn? Sometimes providers don't push the settings to you
what exactly would i put in for my apn? sorry, total noob here :/
Go to menu>settings>system>mobile network setting>access point names. Do u have an entry there? You should. If not, you need to check with your network provider for the settings.
i've just tried putting in the APN settings (copied the stuff from the APN settings when 3g works on the oxygen ROM). is there anything else i havent filled in and should? cuz....it still doesnt work
Not really. Create it, fill it, save it, choose it and restart. Should work, it always did for me
How's the battery life on that rom
Seems ok to me. 3g uses alot of juice since the service is crappy in my country. Otherwise, best rom I tried
dang :/ still nothing... i've noticed something though. when im on my oxygen rom and search for networks..the option "Fido" pops up. when im on MIUI, the option "Rogers Wierless" pops up in the place of "Fido" .___." that may have something to do with it...
Same problem here on desire s.
When I try to change the apn setting I get a force close.
Cheers, Cor
Hey guys, i had a question, and forgive me mod's if there is already a thread for this. Let me know and i'll post in there. But i was wondering if anyone else was having this problem. My shift's gps is not working, nor has it since i got it about a month ago. I've tried everything from downloading gps toolbox, to trying to to update the gpsone tab in qpst. Now, when i go to enter in the server ip address in gps, and the other settings, i write them to the phone, try turning on gps toolbox, standing in one place for 5 or so mins, nothing, not one damn satelite. I go back into qpst, and all my settings in gpsone tab are gone. Wtf? Anyone having this same problem?

When you flash a rom, do you first thing connect up to your wifi before you sign in to your google account?

2) After spending lots of time on GPS I found that getting the first lock is the most important thing and then it just works.
As of this time my opinion on GPS is that I am still unsure as to whether or not fasterfix changes anything but wireless assistance is definitely needed to get a good first lock and is used by some apps in acquiring location.
If you don't get more than 2 satellites in GPS status and it takes a long time to get those 2 satellites GPS hasn't gotten it's proper first lock yet.
This has nothing to do with having the GPS getting a lock in sense. It seems the GPS needs to use wireless assistance first to get the lock (contact sprint servers or something) and then it works pretty well. Still experimenting to figure out how exactly the GPS works and what the optimal settings are for it.

So yeah, try fasterfix and set to north america NTP Server and then in GPS status hit the menu button -> tools -> reset AGPS data and then menu tools -> download gps assistance data

Haha no problem and good luck! Make sure you keep us updated! GPS has frustrated the heck out of me for the past month. That's the best I can come up with at this point. Need to have wireless assistance on and the first time you boot the phone on any rom you should be outside and get a good lock with a clear view of the sky. After that it's good to go.

No just go to GPS settings, turn on use wireless networks, use faster fix, then open maps and try and get your location while outside and with a clear view of the sky. The GPS icon will stop flashing in the status bar when it has a lock. It will stay in the status bar as a solid icon, meaning that it is locked.
Then run GPS status and see how many satellites you get. You should get at least 4-5+ (up to 9) when GPS is working properly.

No longer than 30 seconds if you have good reception.
Spoke with OP via IRC, he is flashed on Metro PCS. Seems like he isn't flashed properly and also doesn't have MMS working. If anyone has any Metro PCS knowledge please feel free to chime in.
I read a while back that there was something that can help your phone lock on to GPS faster. Recently I have been having issues locking on to GPS without restarting my phone. When I restart it, it picks up GPS right away. But if the phone has been running for a few days it always says "searching for GPS" in Maps. Is there something I can flash to make it lock on quicker? So I dont have to restart my phone when I want to use GPS or Maps/Navigation? It has always done this on whatever ROM I flash.
I don't know if it will help with your situation or not but I use an app called GPS Test. Tons of useful info and such. Also allows updating of agps data. My GPS seems to lock quickly

There's a patch for HTC devices that uses an alternate data source for AGPS data. It *might* work on this phone-- I don't know why it wouldn't. Perhaps that's what you read.
Also, the updated Play store fixed an AGPS lock issue with HTC devices. Again, it appears this is only an HTC fix, but it could be what you came across elsewhere and are referencing above.
I haven't used "GPS Test", but there are two different apps named "GPS Status" in the play market. Both allow for AGPS location data to be refreshed, and produced satisfactory results on my HTC Sensation. They appear to be device agnostic, and would be worth a try. I went from a maximum fix of 4-6 satellites on my Sensation up to 12-15 satellites (under ideal circumstances).
Wifi and bluetooth can also cause occasional fix issues-- make sure both are turned off. I get massive GPS lock problems with Wifi turned on-- not so much with bluetooth.
I know this is a old thread but I thought it would be useful if I would share this. It was a fix for the Hercules but since its like our big brother (lol) I think it should work for our here blaze..

I have been living in home town with a nexus 5 as my daily driver for 4 month's but i experienced no error with my maps and gps location but two days ago i moved to a new city from then maps behaves in a wired manner, suppose if a ask for nearest bank or pizza hut it shows wrong locations even my gps in not working properly as when i move it doesn't move with me but for some time stays intact and then all of sudden catches my position, these error are just annoying as I'm new in city and makes traveling difficult..
Can someone tell me the cause of the error ...

Well, it seems that your location fix isnt really working as intended. Now we have to see why.
Please recheck your Location Settings, how are they setup? Go to Settings > Location and check. Try to set to high-accuracy and test again. You need a working internet-connection too to fully make use of this though. And of course, make sure that GPS is turned on, but i probably wont have to tell you that
As a good alternative, depending on size of city at least, is to store the map on local storage. Maps has an option for this. There you can select an area to be accessable without Internet connection, maybe try to use that and see if it works better.
I'd also had this problem. I needed to re-check Location, but also needed to Agree (again) with Google Terms, before I could get Maps/Navigation to work.
