I have a new G2 also modded with Cm7 2.3.2 by my friend but no matter what I try I can not get a GPS lock. It is always searching for GPS. I would like to know if u have that problem, how to fix it, how to go back to stock or any help at all. Thanks in advance

Is there a program called "gps status" installed on your phone? I'm curious because I've seen a lot of people mention gps problems and also mention that app at the same time.

I used that app to use tools reset then reboot and that did not work

You can try this to see if it works.
1. Uninstall GPS Status
2. On your phone, go to Settings>Applications>Manage applications>All>Maps and then click on Clear data
3. Reboot into Clockworkmod recovery
4. Clear cache and Dalvik Cache
5. Reboot
6. Start Maps first before anything else.
Hope that works for you!

There are known issues with CM7, namely GPS issues; everyone is at a bit of a loss as to the actual cause which is causing the delay in fixing.
Your best option, if you need GPS, is to use a stable ROM and not an RC or nightly (as CM7 is); RCs and nightlies are known to have issues, they are released by the devs in order for the more tech savvy users to help them find bugs.

This. And OP you should go check out the nightly thread for CM7 and post there. There is a good 2 pages of discussion per nightly on JUST the GPS issues everyone is having lol. You'll get more precise answers and help there.

I am now using Ginger Villain 1.5 ROM and my GPS lock comes in seconds., Thank you so much for everyone who helped me find a solution. This is a very big relief to me. Thanks again!!

For some reason, no matter which roms I use the Navigation doesn't seem to work though. I've tried MIUI, Virtuous, CM7, and I even reverted back to stock rom I backed up and the navigation never seems to detect my gps. In maps, the GPS locks my location fine, but turn by turn direction doesn't seem to work.
Could someone maybe point me in the right direction?

Are you sure you are using GPS in maps and not your WIFI (which is mapped by google...) to position yourself?
Turn WIFI off, get outside in the middle of your garden and then start maps. Does it position you to the spot or does it stay inaccurate? If it's the latter, your GPS never (?) worked and you got positioned by the location of your WIFI.
What is your radio version (26.0x.xx.xx) and which ROM are you on exactly?

GPS fix? Try flashing radio.
Had the exact same issue, found that all my GPS issues were tied to radio. Flash back to most recent stock version and see if that fixes it. Worked right away for me, regardless of GPS Status, cache cleansing, etc. YMMV

Using my HSPA network (no wifi) and Google Maps "My Location", the accuracy is 600 meters. I'm not sure if that's considered working, but the most frustrating part is that Navigation always just says Searching for GPS. I started off from stock radio radio rom post OTA, then tried to flash:
http://forum.xda-developers.com/showthread.php?t=959488
People said it helped, but tt didn't. Now I'm back on the one listed as "Vision_RADIO_12.28b.60.140e_26.03.02.26" at http://forum.xda-developers.com/showthread.php?t=970809.
Rom is currently QND MIUI 1.3.5 version 1.3. But liked I said, none of the roms seems to be working. Any help would be appreciated.
Edit: I just realized what you meant. I turned off the "Use Wireless Network Feature" and my GPS DOESN'T work! Any way to fix this???

Flashed latest radio and got instant GPS lock (8 satellites) on CM7 nightly #15. Didn't work before with shipping radio.
Latest radio I'm using btw is 12.28h.60.140f_26.06.02.27
Also, ymmv, I've heard some people saying they got big battery drains going to the latest radio, and also some had the same result going to the AUS radio (which apparently has good service).

@symbolism: Ugh, I have no idea about MIUI, but the latest radio does/should fix GPS problems on the latest CM7 nightlies. Anyone else experiencing the same on MIUI in any of the MIUI threads...?
@martonikaj: the AUS radio *is* the latest radio It's the 26.06.something... And I'm one of those experiencing excessive battery drain. It seems to be the connection to the network (Network standby) which sucks my battery empty...

[Q] disabling cell radio?

I want to intentionally disable the phone from making any phone calls. I'm running cm7.1 on my evo and I want it to be like a dedicated mp3 player with android market access.
I don't want to use airplane mode; I'm looking for a more permanent solution that can't be easily toggled.
I tried freezing com.android.phone and the dialer storage with titanium backup, but then market compatibility broke. Market returned server error.
Possible fixes (that I've thought of) :
Disabling radio driver?
Tricking market to not depend on phone?
Some phone or cm setting I'm missing?
Permanent airplane mode that still doesn't bug out wifi?
I know on cm builds of tablets (nook color and gtab) know that its a tablet and not a phone, and doesn't come with a phone option. Short of compiling my own build of cm7 (which if it's easy enough ill do), is there a way to trick cm7 into thinking it's a tablet?

I don't want to use airplane mode; I'm looking for a more permanent solution that can't be easily toggled.

Airplane mode is the only way. Once you turn it on, it's really not easy to turn it back off, you have to go to settings-wireless and networks.

Is there a way to set it and remove the option?

I know on Ubuntu Linux, specifically grub bootloader, and each of the options were available to edit on a conf file. I edited mine on my computer and added and deleted lines on mine. Does the android setting rely on a similar conf file?

I am using tapatalk app and it won't show me all my subscribed threads, but I'm pretty sure in general a guy made a thread about how he did it for an EVO he gave to his daughter or something, it listed what you needed to remove. Sorry I realize that's not too helpful, but I will check back here tomorrow and if you didn't find it, I'll post a link.

EDIT: after reading the thread, i kinda don't want to rock sense. that thread isn't applicable is it? i'll try forking around with my cm7.1.zip and see if i can get similar results.

FFS, if you're the one that's gonna be using it, then just don't make calls. You can always toggle Airplane mode off, btw, to use the market.

Just flash amon ra and r2r going green, its sense 3.0 very stable & clean. It's got a built in option to turn off radio

Two posts above completely missed the point.
A) IM NOT LOOKING FOR AIRPLANE MODE SETTING UNDER WIRELESS AND NETWORKS.
B) IM NOT USING SENSE. JUST NO.
c) what I am looking for is a configuration file, and if you've never edited grub or Apache etc, you'll never understand what I mean. I haven't tried the apk removal yet, but I will in a sec
Thanks for your help pointing to the apk removal thread, but I'm hoping for real developer suppot here

Goodluck finding dev help. They are few and far between for the EVO anymore. I suggest downloading the Android sdk, finding some threads on here and other forums and learning it yourself. Biting the hand that feeds isn't going to help.
Boo

solved. Procedure:
1 Flash cm7 and gapps.
2 Let all the gapps install and update in the background.
3 Install titanium backup from newest updated market.
4 Make backup of dialer and dialer storage (com.android.phone and com.android.telephony)
5 Uninstall phone, and battery pull when it force close loops
6 Uninstall dialer storage after the reboot finishes
7 Wifi should still work the market!

GPS Problems

One day my gps on my Evo stopped working properly and I've been trying to diagnose it with no luck. I was using a CM9 rom for a couple months when I noticed it and I hadn't made any recent changes.
So far I've tried different roms, kernals, patches, and even reverted to stock. I took it to the Sprint store with the stock rom and the tech there couldn't find anything wrong with the gps other than it not locking. He said if it was faulty hardware the gps wouldn't even appear. He actually recommended that I try another kernel or rom, which I've done to no avail.
I flashed the same rom I'm using now, MazWoz B4, onto my other Evo which isn't activated, just hooked up to wifi, and I downloaded GPS Status onto both. I've attached a screenshot with a side by side.
On my bad evo I get no less than 40 meters of accuracy in google maps. On the good evo it's 4 meters.
Any help would be greatly appreciated. Thanks.

lol sell the bad EVO to a dev XP
Keeding. Could be screwed, man. I personally don't know a fix, and if flashing a new kernel and ROM didn't work, it may be broken. But I know nothing of things that technical, hope someone who knows their stuff helps you out.

Thanks for the reply. I've put a lot of work into this little guy to determine a fix for the gps and I just don't want to give up yet! I'm up for renewal but I'd rather keep this thing going and wait until the S4 or another nexus phone comes along. With all the devs out there cranking out roms I don't think it's that difficult to hold off but this gps thing is a killer since no navigation or fitness apps will lock.

I try to give attention to some of these issues, even if I can't really help. Least I could do in XDA, what with all the ROM-making geniuses around, ha.
Racking my brain, there's gotta be some kind of gps code that can be flashed to, you know, format the gps maybe?

Gotta go back to a sense rom for that. Pretty sure I tried that when I first started troubleshooting but it's worth a shot again. I'll report back in a few. Thanks!

I flashed a sense rom and put in the ##4772579#, entered in my MSL which I have grabbed previously, and I'm still getting a huge gps level of error. Even though it says I'm connected to 6/6 sats, I am still only 40 meters in google maps and moving all over the place as it tries to find me. I'm testing outside right where my good evo gets gps within 4 meters.

Fixed my gps without having to unroot

Ok so I'm starting this thread so that maybe it can help somebody who is having gps issues. What I did was flash The ported Synergy Rom. And as soon as I set up the Rom my gps started working. As soon as I opened maps it immediately starting searching for gps and then locked in a couple of seconds. Before when I would open maps I wouldnt even get the "searching using gps " in the notification bar. Haven't tried flashing another rom to see if it sticks so if any of you try this let me know how it works out for you. Im not guaranteeing it will work for you but hey it's worth a shot.
EDIT: My bad, I meant to post this in General. If a mod could move it that be great. Thanks
EDIT #2: Flashed back to Frosty and Gps still works great!

Searching for GPS....

How the hell do I get Google navigation to give me turn by turn real time directions? I did a clean flash of wild for the night 3/8 version. Maps sees my location pretty close, and if I type a destination it will give me directions, just can't get it to go turn by turn, what am I doing wrong?
Sent from my SPH-D710 using xda premium

My friend had this problem. The only thing that fixed it was to download the app "gps status", turn on gps, open the app, hit menu, then tools then clear gps state. Then hit download gps data. Reboot

Tried that, all it says is GPS looking for location... thus sucks

Try this.
Search, read. Then search some more.
There are SO many posts about GPS issues it's silly. I personally have made dozens.
Right now I'm on Stock Rooted GB08, with GB27 modem and GB08 Agat/Garwynn repacked Kernel. And my GPS does work and most importantly will "stop searching for GPS data...." when I close my applicatins now.
And my GPS apps do work outside too.
You may find what you are looking for but probably won't be handed the answer you're looking for.

This phone has been well known to have horrible radios and gps.

On any aosp rom I have to first use a touchwiz based ics one click and get a gps lock. I then power off the phone with gps running and odin el26 then flash the aosp rom. I always make sure to get a gps lock again before the first reboot of the aosp rom. It sounds dumb and time consuming but it works.

I actually got a lock in GPS status. Had to be outside. All is good now. Cleared the data and then re downloaded...got a lock in 2 seconds
Sent from my SPH-D710 using xda premium

Ahah! I knew it. That app works wonders.

Lucky. Ive left my phone outside with screen on for an hour searching for gps.

Tried this again today. Nothing worked. GPS in this phone is useless. I'm on stock rooted tw ROM.

I wonder how true this is. I've never resolved my GPS locking issues either, but never knew anyone with an unrooted phone to compare against. I've had the same behavior with my previous phone(Sprint HTC Hero). It's been going on long enough where I stopped looking for reliable solutions.
Typically, GPS will work great for me after a reboot, even indoors at times. After a day or two, it will fail to lock when needed. I can use an app like GPS Status to reset the agps data, but I have to do it every time I need GPS service if it's been over a few hours since the last time I reset the data with the app. When I get sick of having to use the app to reset data and get a lock before using the app I want, I will do another reboot in hopes to get a longer period before having to use the app again. Many of the fixes I've attempted seem to work at first, but the problem comes back. It's hard to tell if the given fix did anything or if the reboot during the install of the fix is what helped for a short time. I wish apps had the option to automatically reset agps data when being launched, but I'm guessing there's good reason for not doing that. I admit I don't really know what's going on in the background to validate that consideration.
If you are never getting any gps locks at all, and you've tried using the recommended apps to reset your agps data, then you may have other issues. I was running into this after installing a ROM and forgetting to install the required modem. However, that was a much more obvious issue. If you're having GPS issues, I think it's worth noting whether or not you've had any successful locks with your current rom, or if things have become unreliable in situations that used to work. I'm just curious if others share the same experience as me. For those that are used to using an app like GPS Status, how often do you need to reset the data before using a gps app?

Head over to Exit_Only's thread and check out some of his awesome tweaks. But this should help. I know it worked wonders for me. It's from his post. Please thank him, he's been great with updates as well. Check under "Add ons". :beer:

Try it a couple times with a few reboots. If that doesnt work. Try flashing wild for the night 2/15. And try again. If thats a no go then try flashing back to stock.
If at first you dont succeed. Try, try again.
If you still dont succeed, then its prolly time for a new phone

Q: I am running AOSP/AOKP/CM based rom and my data is slow. Also my 3g/4g is not working. Oh yeah and I never get a GPS lock. I don't want to go back to stock touchwiz! Please HELP!!!
A: Well you can't update profile and prl using AOSP/AOKP/CM based rom and it has to be done from touchwiz based roms. But there is some good news. You can temp boot to stock EL29 rom and do whatever you want to such as use dialcodes, update profile/prl etc. Temp boot means that you will be able to boot 1 time to EL29 and then next time you boot, you will be back on whatever rom you were on. Follow this simple video to do this.
