GPS doesn't work anymore, please help me!

hi everybody,
i have some problem with my magic's GPS;
after trying different rom, i came back on cursorsense in order to overclock the cpu with the latest kernel avaible from this forum...
everything seems to be ok but, a few day after, when i needed use copilot 8, gps doesn't work anymore:
no satellites are avaible, no signal (from copilot setup and from other apps like gps status or gps test).
i tried to restore some nandroid backup (with different rom, myhero, smoky cursorsense) but always copilot installs upgrade and gps is still not working...
also from google maps gps location doesn't work.
please help me,
gps is broken???
Ps sorry for my very poor english
thanks a lot

Flash the radio again and possibly with gps on (don't know why this counts, but they say it does). Talking about "with gps on", did you try to reboot with it being turned on ? Oh and btw this is not for dev section and it will probably moved soon...just to point out

yes i've already reboot with gps active but no effect...
but flashing the radio agai i need to wipe (or not?) how i can take gps turned on?
anyway i will try tomorrow morning...
thanks i will reply you.
ps sorry i visit often this forum but it was my first thread and i didn't klnow where to post it...
thanks!

hi, i've tried to flash again the radio today...
everything is ok... thank you a lot for the help or
if you prefere, hvala!
Thanks, goodbye

Mod. edit: not dev related, moved to general

sorry... thanks for putting in order... Bye

Well the subject of this thread IS dev-related, since it's an issue that affects many users of multiple roms, nobody knows what causes it or how to fix it, and is definitely not created by the user's ignorance or inability to read and follow instructions.
OTOH there already is a thread discussing it and it has produced little or no new insight. In short, it sometimes helps to reflash your radio (same version you're currently using), but depending on rom and carrier that fix may be short lived. You're also more likely to have a working GPS on a sense UI rom, but those have their own disadvantages. Users of some carriers rarely or never report GPS issues, while on other carriers these recur often.

Im receiving my Vibrant on Monday... what can I do to limit the issues?

So im receiving my Vibrant on Monday, and from what I have read a lot of people seem to say that you should do a factory reset on it. Should I do this straight out of the box so I dont have to do it later on once everythings installed on it? And is there anything I can do to make the battery last a little longer? such as charge it up all the way, drain it completely, and charge it up again, and do this cycle three or four times or does it not help at all?
What I would like to know overall is what should I do straight out of the box to fix (if possible) the issues with the:
1. GPS (I understand the GPS and Compass issue are going to be fixed in the first OTA update, but until then can I do anything?)
2. Compass
3. Lag
4. Battery drain
5. Should I immediately do the factory reset, or wait and see if I have any issues?
From what I have read, it seems like 100% of people have issues with the phone, but maybe thats just because the people who dont have any issues with it are out enjoying the phone?
All help is extremely appreciated!!!!

C'mon, just enjoy the new phone.

jake...
exuse my most basic of basic questions. I am fairly new to the droid phones.
I see your question of problems with the Vibrant.
Well,you said GPS, and then compass
Well I know what GPS is, and I certainly know what a compass is.
HOWEVER, Not within the text of a phone. Is it simply a compass that is used by a GPS to function?? Again, excuse my bare bones knowledge guess. I should have PM'd you it is so silly. Maybe not
I would love to hear back from you. It sounds like you try to be one step ahead of the game. I would love it if you had the time to take to PM me...could you
My name is Eric (If I hear any more I will pass it on)

i really want to. but i have had so many issues with phones that this time I really want to know if there is anything I can do to prevent issues in the future.

The simplest guide to happiness with your new Vibrant
Reset it out of the box
Root
Install SetCPU
DONE
You should use a black or dark background to reduce drain on the battery and you also have to give the battery some time to adjust. GPS should be fine, but if it's not you should do a reboot first and you should try increasing accuracy before doing anything else. I have my Vibrant and I don't need any of the "fixes" to get a solid GPS lock. Solid enough for now until Samsung issues an update so we can lock onto more sats. I've seen the latest beta perform extremely well, locking on 6 sats at a time with 10Ft of accuracy (moving).

I just got my Vibrant today and was using the GPS just fine without a master reset or anything. Didn't even know there was an issue lol

great! thanks for help. the only issue is the rooting part... i can root a phone if i wanted to no problem, but the only issue i have with rooting is voiding my warranty-my MyTouch was replaced three times under warranty-if i need to replace this phone for any reason I would like to keep my warranty.
now i just have a question tho, how do i increase my GPS accuracy? all i see are threads on 'fixing' it.
thanks for the help,

Increasing the accuracy number (not "accuracy" in the literal sense) can be done by accessing the LBS (location based services) menu. It's under Application Settings from there. The code for getting there is in all of the fix threads. Just increase the stock 50 number to 100 and it should lock a bit easier.
Root, I don't believe there is a way to unroot back to stock. Not 100% sure on that so someone else can correct me. Root would only be useful for SetCPU, the ability to take screenshots and other minor things. No WiFi tether is reliably working right now which is bothersome and one of my biggest reasons for rooting.

great! thanks for all your help. and for the battery, you just recommend using a dark background for awhile and hope for the best, correct?

That's one way to help, make sure all of your syncing is done at the longest intervals and things of that nature.. keep WiFi on for when the screen goes off you have WiFi.

Thanks for the great questions and posts in this thread. It helps.
Alec and Heygrl...I saw you ask about increasing the GPS accuracy of the Vibrant.
Then this code appeared. I have just never seen that. So I just type that in
My GPS is ok at best. If I use the code, and it was't quite necessary, it wouldn't hurt it, would it.
Thank you for your help, and your help throughout the thread

it would not hurt it. if it did, you could just change the setting back to 50.

Wow. You can unroot. There is a working tether option. Very likely you will not have any issues outof the box. Many of us have no issues with gps. You can do a factory wipe immediately after logging into the phone,i just don't see the point (seeing as it just came from the factory).
Strongly encourage you to read the sticky thread.
Also, not sure I see the reason for installing SetCPU, right now, as there are no kernels for overclocking.

[TempFIX] For those GPS still suffer for locked

Just wanna share with u guys regard my finding on how temporary fix the GPS issue. Just follow the step below:
1) Install the GPS test app from market.
2)Open the GPS test app and let it search for the GPS signal and locked it. (this step take few minutes.)
3) after get locked on the GPS test app and open the google maps. you now should be able to get GPS lock in few second and enjoy ur navigation.
my testing rom detail as below:
Sombionix nero beta3 rom
Baseband version: JL1
kernel version: 2.6.32.9
Hope this can help u guys and kindly share ur find out too with diff rom u have by the method I given.
Thanks.

Before anything, thank you very much for sharing with us.
But is this any different than actually waiting to get a lock on Maps? I mean if the GPS test takes "a few minutes" why not just wait for Maps to get a lock instead? I just want to clarify things.

Based on my find out, if just open the maps, it will nvr get locked. while using GPS test app, although still take few minutes but at least can locked the signal.

Running Axura 2.1 and my GPS never works. Attempted your method and no avail.

This method works for me, may be its just placebo effect, but still thanks a lot.

you could have got a lock with lbstestmode(*#*#3214789650#*#*) and then opened maps.

Funny thing is I was using nero 1,2,3 and the obsidian ROMs till now..but I just installed Master's latest AXURA 2.2.5.8. I flashed directly from nero 3 to axura 2.2.5.8 via rom manager without odining back to stock or anything..and magically my GPS locks now in 5-10 seconds.

My gps NEVER worked until I installed Axura 2.1 AND the JL1 baseband.
since then my gps works flawlessly.
it takes about 1-2 minutes to get a lock but then it works perfectly.
try flashing the baseband since AXURA 2.1 comes with JK6 if i'm not mistaken.

do you axura 2.2.1 source? what base is using? I do want to try also...

I don't mean to troll, but this isn't really a "fix," all it does is "prime" Google Maps/Nav so Google Maps/Nav won't give up if it can't find a lock in a set period of time.
There are 3 real "fixes" that exist:
1) Flashing to a newer modem (JL series, take your pick)
2) The hardware fix posted in General from plato which involves improving the contact on the GPS antenna
3) The software fix from the Captivate forums from Da_G that involves changing the jupiter.xml settings for a) removing post-processing and b) using "true" AGPS settings optimized for your network
There are "mini-fixes" that help improve GPS performance (changing SUPL server to supl.google.com:7276, disabling WiFi antenna to reduce EFI), but again these are not true fixes.
Aside from the 3 fixes above, the rest are really just beating a very dead horse.

I dont think its a placebo effect. My GPS was dead until I performed the hardware fix early last week. But even then GM didnt seem to want to lock until I got lock in GPS test first. Someone posted about it in the hardware fix thread. We may have found the hardware problem but apparently there is still a software problem . No matter... Ill take running GPS Test first over no GPS at all.

This method works. I posted about it in General about 2 weeks ago to see if anyone wants to test it but I didnt get any response.
Yes GPS test locks quickly with the JLX modems on the different roms. 8/9 birds within 20 meters in about 20 seconds..blah blah blah. But how many of you actually try to use it during navigation. It works for a while then goes nuts and thinks you are on a street 200 yards away. Sometimes it corrects itself, sometimes it doesnt. Either way it is not reliable.
If you run GPS test and get a good lock then switch over to Navigation. Set your destination. Look back to GPS test to make sure it is still lock then drive. You do not get the jumping around effect. Been doing this constantly for almost a month now without that jumping effect. The key is to make sure GPS test is locked on in the first place. It keeps Navigation from losing that lock and jumping around.

One thing, there are two GPS Tests. Both are nice apps, but for the best lock use the one developed by Mike Lockwood. Open it, start it, and when it locks simply go back home and select Google Maps.
The best true fix is the hardware one. Whatever you do with software is just improvements.

yup. been doing this method for quite a while now.

For me what works and give me a quick lock is going to the GpsRestore Application by Samsung let it restore settings. i don't wait for it to get a lock. I switch to Gpstest application and get a fix very fast most of the time. After that any application that use gps will lock fast.
Hope this helps!

Wow! I can't believe so many people are still spinning their wheels on GPS when a definitive thread which fixes it has been sticked for so long. Especially after someone posted a link to the thread with the fix in this thread.
Heck, the link to the GPS fix was even covered on TalkAndroid in the news section a while ago.

[Q] Searching For Gps problem. HELP!!

I have seen multiple threads on this subject for every other phone but none for the Nexus. Ever since i updated to CM 7.0.2 my gps hasnt worked properly. It locks in on my position and others in latitude very quickly, but if i try to use navigation it stays stuck on searching for gps. When i attempted to use the app gps status to check out the problem, it keeps loading and never finds any satellites. I posted in a g2 thread and the response i got back was this:
"You need to find out what partition on your phone the radio/gps cache is stored. Wipe it. That is the same type of idea of what we are doing here. Hopefully that helps get ya going in the right direction. I would also recommend trying to back it up first if you can. I'm also sure some dev with the know how could write a very easy script for you so that you can't mess it up. But it would obviously have to be someone familiar with the nexus setup. Good luck!"
can anybody help???

I wish I could ban people for this.

Could you please explain your problem, you do not need to open new thread every time.

if no one gives an answer then it usually means no one has the answer. unless you really did **** the guy with the answer's mom.
send the phone to Samsung AS to be looked at.
the worst that could happen is you find out what is wrong and either pay to have it fixed or you don't.
either way you find out what is wrong.

the problem is that the gps don't work, it start to search the signal, but never find it, it is able to find the place where i'm, but in a too big approximation, because i think it is not broken, but may be some sofware issue, can you help me please?

What did you do to try and fix it? Flash different firmware? Are you rooted? Which ROM version? Did you try resetting to factory defaults? Tried some GPS apps (like GPS test)? Tried searching for gps.conf files?
Did you try *anything* before posting here? We are not wizards and can't read minds, really...

1, Have u tried complete reset including all the data
2, If that does not work u can also try flashing a new firmware using Odin and reset the device from setting / accounts / backup & reset
hopefully one of the method will solve your issue

yes, thank you for the answer, my s4 is rooted yes, with the stock firmware. i flashed many rom, and 2 times the stock firmware and the recovery. i have a backup of the efs folder, there is something there about the gps?

Not really, EFS holds the IMEI and such data IMHO. Try downloading GPS Test from the Play Store and test the GPS.

Download GPS Status from the Play Store.
Start the app, go tools/manage GPS state/download.
This will download the assistance data.
Get a line if sight to the sky outdoors or at least beside a window and wait for the satalite bars to turn green.
Remember, GPS will struggle to get a fix indoors.

This topic inspired me and other members to make this kind of topics

Do you have Yahoo! Weather installed? This killed my GPS lock, uninstalled it and GPS works fine again.
If not Yahoo! Weather, think about any other location-aware apps you have installed since it last worked and try uninstalling them.
