So I've done a lot of searching and haven't really found anything definitive. I've found that with some roms I'll lose GPS signal after a certain amount of time (say 10-30 minutes) and have to turn GPS off and back on or reboot the phone. I saw something about flashing a different radio may make a difference. Kinda just wanted to see other peoples thoughts on the issue or if maybe there is something else I can do before I go flashing a different radio.
Currently running CELB 4.1 and baseband 2.42.01.04.27 and I have the issue.. I've had it with most of Tazz's roms as well. KaosFroyo is the only one Ive used that I've never seen the issue with, but I'm really diggin CELB right now and this is the ONLY issue I've got with it.
Have you tried GPS status in the market? I know it will help you lock in a signal, so it would make sense that it would also help keep your GPS locked in.

I have now.. I did the reset and download options in the program. Too bad this isn't something I can quickly test. I'll report back with the results. Thanks!
I have noticed this as well. Last time it happened to me it was 4:30 in the morning, and the "GPS lost" message came up about 180 seconds before I had to make two freeway changes in an area I'd never been before. (CELB 3.9 and same radio as your case). Fortunately for me I had reviewed the route, so I more or less knew what to do.
If I recall correctly, it has always happened after the Nav app had been running for a fair bit of time - at least 30 minutes or more.
However, I don't know if it is something about the root ROMs or not - I started using rooted ROMs back in March or so, so I really don't have a tremendous operating baseline on stock 2.1 ROMs to compare it to. Maybe it is a problem there, too!
If I recall correctly, the last time it happened, I just pulled up GPS Status and asked it reload the aGPS state (without exiting the Nav app), and the Nav app seemed to gracefully recover.
Annoying? Yeah. I don't know what can be done about it, though - like the "undead calls" problem, it happens so infrequently that it is hard to know whether or not a ROM change actually fixes the problem.

I had the same problem with every 2.2 rom I used GPS with. I decided to go back to 2.1 because I have been needing GPS alot more often lately but I havent tested it out since I made the switch. I'll try it out today and report the results tonight.
This same thing seemed to happen on the 2.1, CyanogenMod 5 based ELB by Conap as well. If it is happening with all of the 2.2 ROMs, I wonder if it's just a CyanogenMod issue?
See http://forum.xda-developers.com/showthread.php?p=6812308#post6812308 (this was not the only person reporting it, if you search that thread.)
I really don't think it's ALL 2.2 CM roms though. I've gone on 7 hour car trips with Kaos Froyo without a single drop.. to and from. I've seen another theory somewhere around here about it being certain hardware revisions that act this way with certain software builds. At lease we've got a thread dedicated to this issue now.. maybe we can get something figured out.
Still don't know if the GPS status program helps.. I left navigation turned on for a bit sitting in my house and it stayed connected for the half an hour I left it, just don't think that's gonna be an accurate test with not moving around and all. If it doesn't work I will try a different radio.. I saw somewhere one guy had good luck with a specific older version radio. If that's what it comes down to I'll try.
I have been having issues with the GPS working on both of my phones while using 2.2 roms. I switched to 2.1 a few days ago and I used the GPS on my way to work this morning and didnt have any issues. I also had to flash Senseable a couple of months ago while on a road trip because I was tired of loosing the GPS signal every half hour. It may be a CM thing.
Im having the same issues as well. Haven't found a fix yet..
I've had this issue, after I flashed KaosFroyo(v36), and XTR(4 i think). I recently unrooted using Flashback21 v1 and flashed with the radio included. I have gone back to xtr 5 now and have had no lost gps in over a week. Don't have a clue as to why. hope it helps someone.

give us another update. is the gps problem still fixed for you? Thanks!
I have flashed the radio directly with the verizon zip file that is around and I still get inconsistent results But it always drops a signal eventually in about a 1/2 hour

I've seen it on several ROM's as well. From what i've messed with, it doesn't seem to be dependent on the autokiller memory preset, radio firmware, or amount of overclocking i'm doing. It doesn't seem to be dependent on how many programs are running either. I usually have nav and pandora running while i'm in the car, and sooner or later, the gps poops out.
I feel like it seems to happen less, now that i'm back to using the on-demand governor. but that could just be in my head.
I've had to go back to a 2.1 rom because of it. Its very annoying when the goa signal gets lost right before the exit ramp.

Im thinking of going back to a 2.1 rom as well...
I have also seen the same results on any 2.2 or higher rom. I have since returned to XTRRom 5.0 and have not had a single problem with GPS on any of my jogging runs. I definitely think it is a CM thing. At least on my phone.
Using kaosfroyo v39 and I flashed that sprint phone radio on my eris and haven't had any gps issues. In fact, just the opposite. Mine would lock up before the v39 and the radio flash
I flashed that radio as well and today not one issue at all. Will test more tomorrow
I'm using the 2.42.02.10.29 sprint radio and still seeing it drop out.

Today I even flashed back to the July 2010 version (2.42.01.04.27). the gps dropped out almost every 5 minutes while i was driving around. that's the worst i've seen. So i flashed back to the 2.42.02.10.29 sprint radio again. I haven't seen very good navigation performance on the v1.1 gingershedbread overall, actually. my position on the gps nav doesn't update very often, although it seemed like the voice instructions were still pretty well timed as usual.
Hey guys, bit of a weekend brain teaser for you guys...
My rotation function just stopped working completely a day or two ago. I dont know if its worth mentioning but I actually never use auto-rotation (I just personally dont like/need it much). However, certain programs; Youtube, games, have usually served their proper rotation function when in use.
I've been running SC 2.9.2 with jt's ec10 kernel for quite some time now without any flaws. No changes were made to the phone before the issue.
Kinda sucks not being able to watch Youtube in full screen...
Any ideas?
Interesting. Mine stopped working a couple of days ago as well, also using SC 2.9.2. I'm using jt's 4/7 kernel. I've tried reinstalling both the rom and kernel with no success. In addition to the rotation my compass also does not work, so both the accelerometer and magnetometer have failed. It happened while using Google Nav in walking mode, where the phone froze and became unresponsive. After about 10 minutes of no response I pulled the battery and afterward noticed the problem. I'm planning to revert to stock to see if it helps tonight.
whereas im relieved to know that someone else is on the same boat, i really hope that it doesnt come.down to doing a full back to stock wipe :/
it would be nice to know what caused the malfunction...

Mine's working again after going back to EB01 briefly before going to EC01. I was planning to try out EC01 anyway and the brief revert to EB01 is part of the procedure.
I was driving last night and needed the GPS, I was running BAMF 1.6.1 and the GPS wouldn't lock. I tried apps off the market, had no luck. So I went back to stock and the issue was still there, so i dont believe its a ROM issue...I don't really know what to do and ATM i need to use the GPS lolol so im stuck till i can..if anyone could assist me or point me in the right direction..no pun intended lolol.
GPS is a known issue with the TB. It's been discussed here plenty.
I never had an issue until last night, thought it was odd it was out of the blue. My bad though, tried a search too.

Rebooting TB helped my GPS problem

Download an app from the Market called "GPS Status". Open the app, go to Menu->Tools->Manage A-GPS state. Hit Reset. Then go to the same place and hit Download.
This has helped a lot of people including me. My GPS wouldn't lock on for a good 2 minutes, now it's instant on.

Starting yesterday, VZW and HTC are rolling out an update that issues out a number of fixes. One of said fixes is the GPS lock issue.
Google VZW Thunderbolt Update and you will see it.
UPDATE: Thank you guys so much for the help! My phone is running well so far! The GPS works well enough for navigation, and I should hopefully be able to limp through until my full upgrade. I can't tell you guys how thankful I am that you all took the time to help me answer my questions and get my phone going again!
what would you do? I have a Vibrant, and have done quite a lot of troubleshooting with it. Tmo's tech support said it's a hardware issue and that they've done all they can.
I've tried just about all the Froyo ROMs on it, and things seem to work well for a while, then it gets odd. I regularly clear my call logs, messages, and browser cache. I use wifi whenever I'm at home, and whenever I'm in the minivan I have my phone plugged in.
I am currently running Axura - Moped/FishmanMod v1. This has seemed to work the longest.
Lately, though, I've been missing phone calls...as in, no notification, no log, nada. I rebooted last week and suddenly had a voicemail icon...I had 7 new voicemails. One from my son's teacher. I never knew she even called. I've since reinstalled Tmo Visual Voicemail and at least now I think I'm getting my voicemails. Missing phone calls can't happen though. We don't have a landline, and we have a child with health issues. I have to be available.
Other issues:
*My battery died about halfway through the day yesterday, even though it had charged fully overnight.
*This thing is slowing down. As in, taking a photo with my phone isn't really viable. By the time it finally snaps the picture, my kiddo has grown an inch.
*Lag! I'm using Swiftkey X and it often hangs on a key for several seconds before finally typing it. It's very slow to open apps, etc as well.
Does anyone have any more advice for me? I'd love to run an ICS or JB ROM, but having the ability to call 911 is not negotiable for me. Woodrube and some others have given me some great advice, which has helped, but I'm still having some issues.
I could pare down the apps and use it just as a phone, but what would be the point of having an Android...and data? I need the calendar, email, task list, etc. to keep track of everyone.
I'd love to try to figure out how to make this phone last longer. I could upgrade now, but our checkbook doesn't like the idea.
Personally I'd Odin back to stock JFD and either do a reflash or pick a new ROM (bionix comes to mind).
Could do a fresh install of the apps you want on your phone. Your battery could be going bad and may need to be replaced, and if your sim card is getting old, you may need to stop by T-Mobile and have them replace it.
Not sure if that could be the trouble with your notifications or voicemail, but they are all quick things to try that should be cheap and quite possibly very effective.

Well, although it isn't too helpful to say...I honestly believe that if you simply must be available because you have a child with health issues, you definitely should not be tinkering with your device. True, my phone runs better, faster, stronger, and longer (ha daft punk) than it did running stock, but I have certainly had the occasional issue such as data issues, force closes, battery drains, SODs, etc, etc...it's simply a fundamental part of the life of modifying your phone. It's not to say that you won't have issues if you kept it stock, but you really shouldn't be messing with your phone if you don't have a land line and you NEED to be available for something so important.
Now, onward!
I will look into similar occurrences of your problems and report back..(sorry in class atm, then off to a meeting). Until then, Gl!
you could try and use a cyanogenmod based Rom. They are one of the best roms out there except you can't as of right now call 911 (some phones can and some cant ) also gps is semi-broken.

Thanks for the advice, but not an option. I have to have 911 capability, and we're pretty active geocachers, so my GPS gets used a ton. I've been so tempted by CM Roms, and my husband is rocking one on his One S, but going without 911 isn't an option.
After this last round of my phone's slowness, we did ODIN back to stock, then did the ((*^&^%$*&^) updating it to Froyo. (Yay!) We were hoping that taking it back to stock would help our issues, but it actually seemed slower. (And oh, the agony of using TouchWiz!) I very, very carefully added back ONLY the apps I used on a daily basis, watching carefully to see if there were any issues. It was crazy slow.
We then went to this last ROM and I added back apps even more slowly. I noticed that I had issues after I put the Zedge app back on, so it's gone. I also noticed that it acted funky after I put Google Goggles on, so it's gone as well.
I am not, by the way, storing any music on my device. I stream it through Google Music.
I do have another battery for it. I'll put Battery Calibration on and swap batteries to see if that helps. Good idea.
Also, my SIM is pretty old. I hadn't thought about seeing if I could get a new one! I know it solved some issue LONG ago with my BlackBerry. I'll see if I can do that at our TMo store today. Appreciate that suggestion.
I've been just about the give up on this phone altogether and just going with the One S like The Hubs, but forking over the money for it (not to mention that it would be $200 for me and $49.99 for a new contract!) is just not in the budget now. Might be getting close to something we just can't avoid though.
Try flashing back to stock 2.1 with repartition checked. Then flash one of Fishman/Moped 2.2 ROMS ( he has odin files if you prefer that method). I think you may still have some "ghosts" left behind from the last ROM or two you had on your phone. A fresh odin to stock with repartition checked should get rid of any "ghosts". Also when restoring apps make sure you restore app only, not app+data. Remember, after installing a ROM allow your phone to sit for a good 10 minutes then reboot before you use the phone.

That could definitely be it. I used to just restore all my apps+data with My Backup Root. I'll see if I can convince The Hubs to help me work on the phone this weekend. I'll let you know how it goes. Thanks!
Okay, we did the repartition flash, then put it on FishmanMod Blue 2.2 Frankenstein Slim. Seems to be running a little better, but now my GPS won't lock at all. I've rebooted, tried Samsung GPS Restore (never locks) and GPS Test. Test sees 4-5 satellites but doesn't ever lock on. I've tried Nav as well and it is not able to lock on.
I've checked our forums and I see a lot of fixes, but no recent fixes and most of them are for 2.1. I've tried dialing the *#*# numbers, but they don't do anything.
I sure could use some suggestions. I'd like to be able to use my GPS. I know it's generally an issue with Vibrants, but mine has never failed to lock on before. Might be slow, might take it until the end of the block, but it always locks. Until now...
Thanks in advance!
Go to the Dev section and look for a thread called GPS Fixes by Solisfiend. It'll be buried way back and I'm mobile so I can't link it. It has directions and app to fix Froyo GPS.
I have 2 posts in there, 1 is clarification of some things and the other is a download app you can use. Should work well for you.
Thank you, Woodrube. I'll do just that.
ETA: Found the link.

I recently started using my wifes old fascinate after I broke the screen on my Droid Razr. I had rooted it for her in the past and was running AOKP ICS. The phone was performing well but gps tracking seemed to be seriously lacking. So messing around with it I noticed it was running the ED05 radio. I figured i'd upate to EC09 and see if that would improve anything. I used to Odin to flash EC09 rebooted phone and I had nothing 0/0 fix/sats in GPS status. I toggled it on and off and tried resetting GPS data and let it sit for a long time and got no lock.
So I said what the heck I wanted to update to Jellybean so lets flash a new rom and see if the clean install helps. So I flashed hellybean from recovery and the rom runs great but still no GPS. So i'm thinking okay..weird...let's try another radio. Tried flashing EH03 and same issue. So figured i'd flash back to ED05 and hopefully that would do the trick. Well now I'm back on ED05 and the phones been sitting for 10 minutes running GPS status and still hasn't found a single sattelite.
Any ideas of something to try? I use GPS for tracking a lot and really want to get this thing working. I am out of ideas.
Maybe you should try the app GPS Test by Chartcross. Install it, go to settings, and hit Clear AGPS.

Thanks for the feedback. I eventually got it to work and felt like an idiot. The trick? Walk outside...
I did a full factory reset and reflashed hellybean tried some more radios and was about ready to throw the phone at the wall when I said what the heck lets just go outside and see what happens. Walk outside and was locked within 10 seconds.
For some reason the fascinate GPS will just not work sitting on my desk at work. My razr had no issues here so I guess that's why I was expecting it to at least find something. I guess this GPS receiver is just weak.
The wavelength GPS is on has the property of not being able to go through buildings. While this phone's GPS is pretty rotten in this case it's not really Samsung's fault.
