Gps issues can't lock location - T-Mobile LG G2x

Anyone having problems with their GPS not able to lock a navigation? I took a family trip to the beach this past weekend and while I was navigating I loss signal. Also when searching for route it takes about 5minutes to find the route. Is there a fix for this??? When using my gf sidekick 4g it locked onto a route right away.

What version baseband do you have?
If you have the old baseband, there are a number of apps that can help such as bloater and GPS Status... but nothing will getting it working 100% better than updating the baseband to the July 15 version.
Unfortunately, however, there is no flashable zip of the baseband so in order to get it you have to backup your current rom (whatever that may be) revert to froyo (this can be any froyo... stock, EB, doesn't matter) and use the LG updater to get the new baseband and GB update.
Then you can re-flash CWM and restore the backup you made.
Since getting the new baseband my GPS locks have been instant outdoors and 30 seconds to a minute indoors.

I had gps signal lost issues with one of my g2xs. It looses signal 2minutes after a lock. After that no lock until reboot. Got it replaced and all is good now.

Mine takes up to 10-20 to lock some time. So I use copilot, which is not a better navigation but lock much faster.

Navigation and 4G Problems

I am stuck on the Evo Shift 2.3.3 I am having problems with my GPS and 4g.
I live in the heart of Boston and my 4g signal is horribly weak. Also whenever I use my gps (ANYWHERE) It can find me just fine, but when I do Navigation for driving, it just says "Searching for GPS"
Any help?
Is it possible to update Radios without a rooted phone?
I think you have the most current radios with 2.3.3. Pretty sure you can't flash with a locked bootloader anyway. Could be wrong on both counts tho, never been on the stock 2.3.
You try clearing data on telenav? How does google maps nav work for you?

I always use the google navigation. I never bothered with telenav because I thought you had to pay for it.
Try turning on your WiFi when using GPS. It helps lock the signal quicker. As for your 4G you can try this THREAD . I use it with good results . Also , if you want to speed up your data you can try the info on HERE . Both of these can be done without Root. You just need your MSL. I usually just call Sprint and ask for it.
Followed the 4G and 3G tutorials, it was doesn't difficult to get the MSL number, quick call to Sprint, made a joke and stuff with the Tech and he gave it to me with no question.
*Note* I always make jokes and stuff with all the Techs.
Anyways, Turning on wifi even though I am no where near Wifi signals helps GPS? This is like my fourth Sprint Android device and I've never had so many problems with Navigation.
Yes turining on WiFi helps. Even though your not connected, it helps lock quicker. I can dig up the thread that explains it if you would like.

No gps while overseas in airplane mode

I am overseas and can not get a gps lock. I am using stock ep3h. I didn't think this phone was tied so closely to agps. anyone had this issue or solved the problem
If u can get to the market, download faster fix, and set the region to the country you are in.... requires root

fasterfix offers no help. any other suggestions
Faster fix will change your region if you can't use GPS after that you must have a different problem,

yes I have another problem. does anyone have any other suggestions
Airplane mode will turn off all radios including gps.

unless the charge is different gps is not tied to airplane. I have a few other phones that work in airplane. I have also tried in non airplane but I still have no cdma service. can anyone confirm that there gps has worked overseas with no cdma service?

Not if you're using offline maps that are completely stored on your phone. There's no need for a data connection for those.
I also use the GPS in airplane mode all the time while I hike in the mountains where there are no cell towers or wifi, so I understand where you are coming from. I use google MyTracks all the time while running and hiking.
I am not sure how to fix your issue, but I have a few ideas for you to try.
First, when you move over 100 miles with a gps off and then turn it on generally you will need 45 minutes to 1 hour for the gps to realize it is somewhere new.
Download GPS Test and GPS Status. Give them each a try for 15 minutes outside. These apps have some strange magic that has fixed several of my phones just by running them for a bit.
Let me know how this works out.

I have had it outside for 2 hours with no lock. gps test is no help
any other suggestions
Lets get a little further into the issue then... You stated no lock. But did the GPS ever pick up any sats? If so what were the sat numbers?
I have seen 6 satellites only once without lock. I normally see 0 to 3 with zero most of the time. it is seeing some of the same satellites my other phone with a full lock is seeing but this phone will never lock. I just think the agps feature is so embedded that the receiver is lost without it's data. which sucks because I center still the offline gps features on this that my cheap world phone doesn't have.

T-Mobile subscribers: How is your GPS before and after modifications?

The G2x is my third Android phone. Prior to this, I had the Optimus M on MetroPCS, then the Optimus V on Virgin Mobile. GPS and navigation worked amazing on the Optimus V and would lock on instantly.
When I first got the G2x,I noticed that GPS was practically unusable. By the time it takes for the phone to acquire a lock, I'd either be lost or already at my destination. Before I had my phone rooted, I'd access the LG secret menu and try to make changes there, but it didn't seem like anything made a big difference.
I've been rooted for a few months now and running various ICS ROMs and GPS is still hit or miss. Sometimes it'll lock at a reasonable time, others it's just wasting my battery and not helping me. Then, even when I am locked, or often will lose the GPS signal and have to search for it again.
Is this a T-Mobile thing or a G2x thing or is it my location? I live near Oakland in the SF bay so I'd think we'd have good service over here.
What is your experience with GPS on this phone and carrier? I honestly want to switch to Sprint once my contract is up (and might even terminate early). Thanks to the development community here, the G2x is finally a decent phone, but I've only been unimpressed by T-Mobile's service since coming from Virgin Mobile.

GPS has nothing to do with T-mobile. It has more to do with the phones hardware and some with it's software. The newest baseband that was just released for the G2x has fixed all my GPS problems I get a lock quickly now and it works great for navigation and it also improved my call sound quality, but there is a lack of custom ROMs for the new baseband currently the best you can do is the rooted stock V21Y.
So basically stuck with nad GPS unless o want to update baseband or get a different phone?

i basically had the exact same experience as you are describing. But, only while I was on the march 2011 baseband. is that the same baseband that you are on? Fortunately once i upgraded to the July 15 2011 baseband i now have instant locks. (and can flash any custom rom with instant locks. primarily stock 2.3.3 roms. Any higher i usually run into slow lock times Ex:Cm7 based roms.
The new March baseband is the only to fly. Here's my lock in under 5 seconds.

You genuinely want to upgrade to the new 21y firmware, I was Oakland CA today and I had no problem using Waze to navigate around the big mess on 880S on way to airport. GPS on my g2x was way better than the iPhone from work, but never would have been able to do that with the older 21e firmware.

No Signal on G2x

I've had the G2x since it first came out and have always had issues with the signal dropping abruptly. However, since Thrusday, I have lost all signal to the tower and am unable to get it back. I was running EagleBlood's ICS ROM but have since done a full factory reset back to stock and completed an update via the LG Update Tool (I wasn't successful with updating the baseband any other way). Everything appears to be back to factory settings, but I'm not receiving any cell signal still.
Any ideas?
My baseband currently reads: M6600A-SCAUTNZ-2.0.9720T 1 [MAR 2012 10:00:00] MP:TRULGE_08.09.02R_MDM
When I choose Status under the About Phone menu I get the following details:
Network: Unknown
Signal Strength: -93dBm 10 asu (fluxuating slightly)
Mobile Network: GPRS
Service State: Out of service
I am also unable to enable Wifi calling. Basically the only calls/texts I can make are via Google voice on a wireless network.
I'm on the stock 2.3.4 rom currently.
Try a factory data reset and a battery pull

I'm not sure what I should be checking. Is there a good article/thread on this?
I too upgraded to the new bb, and have been getting random signal drops. IDK if it's Tmo, working on their equipment, or the new base band. I figure I'll give it a week or so, as it hasn't yet interfered with my daily usage (mine drops, then comes back).
My suggestion to you, since your loss seems to be a constant, is to try using kwes 2.3.4. I had some other minor issues w/the LG release, that I don't seem to have with kwes. It's a bit more stable.
http://forum.xda-developers.com/showthread.php?t=1602798
Could just be that you had a bad install. It happens. Give kwes ROM a shot. Maybe that'll take care of it. Good luck!
Thanks for the suggestion. I'll go ahead and give that a shot, but I think in actuality something internally might be messed up.
Have you tried a diffrent sim card?

Random Signal Drops?
I have the some freaking problem, I made the thread above and I've tried a number of fixes and no dice.. Tonight I'm going to try to get a new sim. I've tried a complete reset, Rooting and removing all bloatware, and flashing a custom rom. No dice. Sometimes I drop from 4g to 2g, sometimes I drop all signal. Wifi never drops but I lose all connectivity to mobile data and signal.

No signal except wifi
Did any of you ever fix this issue? The same exact thing just started happening to me. I had to start using a back up phone to make calls. The only thing that works in wifi and I've verified the APN settings. I even took the sim card and put it another phone, which worked fine. Let me know if you find anything.

If you want to eliminate the phone as being the issue, has anyone suggested you roll-back to the previous Baseband and try using one of the CM7 ROM's that are out there?
Logic being, if the rollback gives you the same issues you previously had, then it's not a function of the baseband causing the issue.
So I have the G2x with simple mobile and just installed the latest eaglesblood and obviously I cant make any calls and texting works with wifi so is this fixed or should i go back to 2.3.4

If your having the same problem I use to download the app “GetRIL" from the play store and check to see if your base and and RIL match if not download the right RIL within the app hope this helps! Just saying when I changed my RIL I did lose signals once in a while for a couple days I think but now I can't even remember the last time I have

I moved from Baltimore to Denver a couple months ago. When I got here my signal was horrible. Data would hardly work, GPS constantly giving out, extremely frustrating. I went to a Tmo store and they gave me a new SIM. Works way better now.

[Q] Cellular phone connection dead from one minute to the next

So...
I am running my phone rooted, but mostly stock (just some removals) with ROM 1.53.401.2 and he 0.15.3150S.19_10.31501S.06L baseband.
Its been perfoming fine ever since so I never bothered to upgrade to a custom ROM or the newer basebands.
Its an EU unbranded phone. As of tonight, with nothing special done to it it seems to have lost all cell reception. All I get is An x where the 5 bars are. Funnily, when I turn of my WiFi router and select wireless internet, I can get online and download data through the cellular inetnet connection. But not a single call or SMS will go out.
I have moved to like every location in my apartmant and outside and nowhere I can even get a single bar of reception or even a call through.
Does anyone have any idea WTH this could be, what could have caused it? Any ideas on where to prod and poke for a solution?
Mine did that for the first day after I put a non-stock ROM on it...hasn't done it since. I took the piece that covers the SIM card off and popped it back on. I don't know what causes it though.
