I am having some issues with the GPS on both my EVO and my Wife's. Basically about 90% of the time It wont lock on using GPS, but rather using the cell network. Now when it does lock on using GPS it is almost scary how accurate it is, but usually the GPS wont lock on.
We are both running:
CM7 nightly
Tiamat v4.0.6 SBC
Radio 2.15.00.05.02
WiMAX 27243
PRI/NV 2.15 003
Both phones are on MetroPCS, fully working with 1x data, and have flashed the MetroPCS Evo AOSP MMS & Web Script v4. Also I have done the ##GPSCLRX# Fix using the Sprint lovers rom.
Is it possible that the recent radio update has anything to do with it? Or could the kernel be affecting it?
you need to look into flashing the Visions GPS driver that Galandy fixed up for us.
http://forum.xda-developers.com/showthread.php?t=1132412&highlight=aosp+gps
the top one, the qualcomm vision gps driver 1.1
should be good
If you read the faq's for cm7, you would know that the gps is flaky with that rom. I ran that rom for 3 months and always had problems. Some phones will have the gps work fine with that rom, but most just dont work at all.
This could be better placed in Q&A or CM7 discussion.
I am not familiar with Metro, however, you can get GPS status from market. I highly recommend it and it clears data plus downloads assistance data to get even better results.
Also, check out these fixes:
http://forum.xda-developers.com/showthread.php?t=1132412
I recommend qualcom v 1.1
Ok so I am flashing the Qualcomm driver as we speak. oddly enough my GPS works fantastic at home, so I wont be able to post my results until I go to work tomorrow. But I will post back as soon as I am home. Thanks, I had no idea there was a driver update. I have my fingers crossed.
Ok, wow! of course I wanted to test it before I left in the morning. Now before flashing the driver my GPS would place me almost dead center of my apartment complex. Now its actually pinpointing my unit. So I haven't been able to do a big test yet, but that's pretty impressive already. Will post back tomorrow after really trying it out.
Horrible. Unfortunately, there was no difference.
Looks like im on the hunt for a new rom. I've had it with cyanogen anyway ever-since the issue with my screen not coming on when i get a call.
Any suggestions?

Hi, i am currently using MCR 3.0 and everything is good, however, the GPS doesnt always get a fix. I can see with GPS status that it can see like 10 sattelites but cannot even get a single fix after 30mins. Sometimes it works really quickly, sometimes it doesnt work at all. Does anybody have a fix for this problem?
What Radio/Baseband are you using?
Right now I'm using 63.18.55.06JU_6.35.08.29 and am experiencing similar issues.
I may consider jumping up to 63.18.55.06JU_6.35.09.26, which is supposedly much better, but apparently it kills WiFi as well.
mm radios affect the GPS and wifi as well? i always thought that it only affects the phone reception. right now im also using 63.18.55.06JU_6.35.08.29, maybe i'll try upgrading it.
Well, unless it's any different than when I had my HTC Vogue, yeah, the Radio affects every wireless function of the phone essentially.
Just be careful upgrading to 63.18.55.06JU_6.35.09.26, one user reported that the WiFi issues became permanent for some reason.

i am using 63.18.55.06JU_6.35.09.26 with MCR 3.0, no wifi problems for me. used it on the Hero21 1.7 with no problems also
Interesting, interesting... Now I'm tempted.
I'm on the stock (downgraded, rooted) ROM right now. I wonder if it will work properly.
i upgraded it, the wifi seemed to be much better now but i didnt see much difference with the GPS
there have been pletny of GPS threads, obviously. but im wondering what you guys did to fix yout GPS on cm7? my gps worked in the past, but recently when i flashed RC4, the GPS stopped working. and i flashed the latest nightly and it is not working as well. i just baffles me because it worked in earlier builds, and you would figure it would work in more stable builds.
so.
what have you guys done to fix your GPS/what nightly are you on?
As an avid Foursquare user I use GPS every day, several times a day, these GPS issues are the main reason I'm still on the stock ROM.
i know what you mean. my GPS works on sense based roms, which is great. im not sure whyyyy its not working on CM7.

First things first: No indicator on notification bar when starting GPS traffic assist application?
Then you are living under a rock or having bad reception. Go outside. Using some kind of widget which uses GPS also and has a on/off switch in it? Try switching off and reboot. It simply should work with the latest nightlies. Try reflashing and fix permissions. Do not wipe your entire phone before flashing.
Doesn't work for me either with RC 2 or RC 4. I've tried some of the fixes out but no joy. I know how to use it and it works fine when I go back to stock. Issue is definitely with my CM 7 install. I'm hoping for a solution soon as this my only issue, but it's a big one for me.

I don't use the navigation much but if I understand the program gpsstatus, it is working for me. I have used CM7 RC2 and RC4 (which is what I am on).

That's right, yours is working fine. If the GPS is "broken", you won't have any activity on GPS Status. No green dots for the satellites on the round display, and no bars on the bar graph below that. Those will be blank, and you never get lat/long coordinates
It's still working for me on RC4, but locking takes about a minute, whereas it was almost instant on stock.
CM7 definitely does something to gps, very weird how everyone is getting different results.

had problems with gps locking on stock radio with cm 6.1.1 after flashing .27 i get almost instant lock in the house, that did not happen with stock rom or radio.
but my wifes with stock radio and rom did that from the box
both g2
GPS doesn't work at all for me in CM7-RC4 (I mean nothing, no signals or indicators or anything). Works fine in CM6.
I believe I'm currently running the "stock" T-mo OTA radio 12.28b.60.140eU_26.03.02.26_M and haven't tried a different one. Think changing that might help? I don't understand why some people have it working with this radio but not others.
Edit:
OK, I got it working. I had first installed CM7-RC4 using clockwork recovery (in the boot menu) after wiping out the stock ROM. GPS didn't work so I installed CM6 using ROM manager. GPS worked. I then installed CM7-RC4 using ROM manager and voilà, GPS works in CM7-RC4 now. I have no idea what the difference is.
Try .27 worked for me on cm 611 , just flashed the new one, works great, satellites get higher value on GPS test

Sorry, didn't see your post after mine. I edited mine to show that I got it working simply by downgrading to CM6 then upgrading to CM7. Could be a ROM Manager thing or maybe something left over from how CM6 configured the hardware, or who knows.
I do wish CM7 was more stable though, seems kind of wonky.
I had the same problem with CM7. Download gps.vision.so from either nightly #4 or nightly #34. Open up adb:
adb remount
adb push gps.vision.so /system/lib/hw
adb reboot
GPS should work after that.
Radio .26, CM7 RC4, flashed also the "auto-patcher" that patches files to your ROM based on what radio you have.
Okay, recently I had an issue where on my Evo the GPS would not detect any satellites at all. When I use applications that require the gps such as google maps and gps status the gps icons blinks indicating it's in use, but I never get any signal. On gps status no satellites show up. Currently I'm using sense 4.22 rom, I also tried with 4.24 and cyanogenmod and still no luck. I also tried the sense fix with the ##gpsclx# (something like that I think) and still no luck. Any suggestions?
have you tried that yet?

Okay tried one of the drivers, still didn't work, I'm going to try wiping everything and re-installing the 4.22 rom
I've run into the same problem myself.
I've been switching between cm7 nightlies and mik's. Initially things worked just fine, but in the last day it won't get a lock. All I get is a flashing gps icon.
Tried the different drivers floating around, gpsclrx, etc. Not sure what to do at this point either.
Yeah, I just completely wiped everything and installed a fresh rom and still nothing...could the radio's have something to do with it?
I did that too.. No go.
I restored a sense rom, did a profile update, reboot.
Surprisingly, that seemed to work. Trying all the other things, I never did the profile update. So who knows... ymmv.. Good luck!
Btw, if you're on an airave, turn that off if you can when doing the profile update.
Okay thanks I'll try that.
If you don't know what it is, you don't have one.
An airave is sprint's version of a femtocell. A mini tower that uses your cable/dsl connection and broadcasts a low power cell signal. Used for areas of no/weak signal.

Okay so I just tried it, and rebooted multiple times but still a no go. What version of sense did you do it on?
I actually restored back to mik's 2.1 rom. Any sense should work though. Of course, as screwed up as this is, it could have very well been coincidence?
Hmmmm....okay, I think I'll try going back to a froyo rom and see if that works

Okay I don't know I'm about fed up with this. I have tried everything and nothing works. The GPS simply won't pick up signal!!!
Okay just another update, still nothing is working still says searching for GPS none of the Gps apps pick up signal, could this be a hardware issue?
Lol, okay I know I am practically talking to myself, but I just remembered something. About 2 weeks ago I went to the Sprint service center to have my back camera lens replaced. However, I haven't used the gps for a few days after that, but later that week, I noticed that it wasn't working when using my jogging app on the phone. So today I read online that someone else was having gps issue also, and it was the fact that a little connection in their gps antenna came loose. It could possibly be that while repairing it, they accidentally knocked out one of the connections to the gps antenna. I think I'll head over there tomorrow.
Good luck!
Evo HW 003
MIUI 1.6.17
Okay so I just got back from the sprint store. I told the guy about my problem. At first he insisted it was working because in Google maps it shown my location but then I informed him it was just satellite signal. Lol so anyway..after about 20 minutes they decided it just didn't work, they're ordering a replacement phone which should be in, in about a week. Lol fun stuff
Glad you're getting it resolved.
As for me, anytime I have the device connected to the airave, the gps fails to acquire any satellite signal. As soon as I kill the airave and the phone connects to a tower, gps returns. This was not the case before, but the airave has been troublesome more times than not.
Practically however, you're obviously going to make use of the gps when not home, so it's somewhat of a moot point.
Lol yeah...well at least hopefully the replacement phone will work well...now..I just have to deal with rootig that
Okay another update my phone came in early, and the GPS on this one works!!!!!! Yay!!! Lol..now i'm just waiting for a root method hahaha
I'm kinda at the end of my rope trying to find a non-stock ROM that doesn't break GPS. I've tried several so far. I can't use any CM7 ROM or anything based off CM7, as GPS is useless. Recently I tried MIUI Bulletproof and loved it, but sure enough, GPS would lose signal during GPS Navigation. The only ROMs that consistently have fully functional GPS for me are the rooted Gingerbread official release and some variations like G-Lite.
There's nothing wrong with these ROMs, but I'd like to run something that has the insane speed and increased functionality that the awesome devs here and elsewhere create. It just get frustrating finding a cool new ROM, loving all the features, then finding that, as always, GPS constantly drops connection or fails to lock at all. I've done all the tricks like efs_wipe and even a proposed workaround bug fix in the General section, but no joy as of yet. So I'm back to vanilla 2.3.4. Nothing exciting, but GPS is flawless. Anyone have any tips of ROMs I may have not tried where I can get best of both worlds? Figured it won't hurt to ask.
Interesting. I'm running CM 7 and my GPS has been working fine. Assuming you did a full wipe between installs and all that recommended stuff?
Yup, I always do a Superwipe+ that does a good scrub as well as wipes the efs partitions. Plus I manually wipe the Dalvic cache. From what I've gathered, random G2 users just cannot avoid GPS problems running anything that isn't stock. CM7 and MIUI give me major GPS woes, whereas stock ROMs give me no issues whatsoever. I've been trying to get to the bottom of this since January and not much luck.
Are you sure u got no hardware problems with ur phone/gps?
My gps is working very good @cm7!
I got the same issue you said with me hd2... gps got lost, never found gps, phone freezes @navigation...
The end of the story was that my hd2 has to be repaired by HTC.

I feel like you're not going to get anywhere with this, since you've obviously tried ROMs that work fine for others. I had problems with GPS on CM7 before, but a efs wipe (and performing Superwipe+ thereafter) fixed any and all issues. The only thing I can think of is to try CM7 nightlies off of CWM (a few user reviews under each) instead of the release. I'm on nightly 204, and everything from GPS, to performance, to battery life is flawless. There's always the option of getting the G2 replaced and trying again.
Good luck!

Well, he did say he has flawless GPS on stock 2.3.4, so we can safely rule out actual issues with hardware.

Exactly. Since GPS works perfectly with stock ROMs, I have to rule out hardware problems. If it was a problem across the board, I'd already have a replacement in hand. The only thing I have not tried yet is RIL matching. Can anyone link me to it? I know the dev who had it up on these boards left XDA and took all his stuff with him. Not sure what it involves or if it may potentially help, but maybe worth a shot. I've tried flashing a few different radios and am now on the "official" radio that came with latest OTA update.

Thanks for the links. I've tried efs wipe several times. Done it manually via terminal emulator and flashed the zip/superwipe+. I'll look into the RIL matching. The GPS config options appear to be specific to Verizon and the Samsung Captivate, so not sure if that one is an option for me. Thanks again for linking me to all this.

Changing the GPS server should work for any ROM,Im using unity and in the uk so not carrier specific just a matter of opening a file and changing the server values,
Luckily I've never had any serious problems with my GPS so I'm running out of ideas,there is also an app called GPS status is useful but if wiping the efs data is not helping then not sure if the app will help,best of luck finding a solution
You should check out the latest "unofficial" ILWT CM7 212b by tsubus. He includes an option to use stock HTC GPS drivers. I updated my radio to. 30, and flashed 212b (which includes the efs data wipe) and my GPS works flawlessly now. Highly recommend it. Link is in my signature.
All features are now part of/options in version 213, and all subsequent releases. Seriously, it's worth a shot...

So about 4-5 months ago, I became frustrated with the GPS woes on my otherwise perfectly operational Evo 4g and went ahead and bought a "refurbished" Epic 4g instead. I miss my Evo 4G like crazy and with work slow for the next couple weeks, I decided to revisit the issue to see if i can maybe fix the problem and re-activate my Evo 4G.
I am a relative n00b but know enough to have exhausted every possible solution I could find using the "search" function. GPS Status AGPS resets, ##GPSCLRX# fixes, as well as pretty much every single driver fix listed here: http://forum.xda-developers.com/showthread.php?t=1132412
thinking back to when the issue began, I think what I did was install a CM7 AOSP ROM over my then stock-rooted ROM, when the GPS didn't work, I kinda freaked out and nandroid flashed back to what i had before but the GPS issues persisted.
I thought about unrooting completely back to stock but if the GPS is the only thing not working, I'm wondering if that would even fix the problem.
It could be a kernel issue perhaps? I'd be more than happy to provide any info/screenshots/logs that might be helpful.
Any thoughts/suggestions would be very very much appreciated
*Edit : in the time since I made the post, I decided to follow this thread and install everything anew, ROM, kernel, GPS drivers/fix (AOSP all the way, CM7 + Savagezen + CM7 N39 Driver ). Still nothing with the GPS, the GPS Status app just will not lock on to a satellite.
