[q] gps not working?

I have a ATT TP2/Stock Radio and have been flashing ROMs for a long time... I recently flashed to the latest ENERGY rom and after a day or so the weather for "My location" quit updating?
I figured it was a bug so I flashed to another one of his ROMs. (I always have used his ROMs from my 1st flash) The phone will not find a GPS signal to update my location. I went back to a tried and true oldler version of Energy, which worked in the past and still no "My location" weather?
Google maps cannot locate any satilites either?
I flashed back to 1st ATT stock ROM loaded google map, searched my location and it worked... So they phone is still working properly.
Flashed back to ENERGY ROM and back again to no "My location" weather or google map GPS?
I have tried everything I can think of please help...

Perhaps you have already done it, but have you performed a task 29? If not try that, then flash your rom.

Both the My Location and GPS issues are discussed (with possible solutions) in the Energy ROM FAQs, Post 6 (of the Energy ROM thread) Section 3 "Solutions to Issues":
http://forum.xda-developers.com/showpost.php?p=4579513&postcount=6
"My Location" is derived from cell tower information, not GPS. Issues with My Location may be a function of the cell tower at your local area, either low signal strength, or just not passing the proper info to your phone. If you travel to a location a few miles away (or farther) do you still get no location?
I have the ATT Tilt2, same as you, and have flashed Energy ROM many times (including most recently Oct. 8), and have never had an issue with either My Location or GPS. There are some ATT-specific solutions you can try, listed in the FAQ. Also, updating to the newer radio (one shown in my signature) may help.

Will do...
I do perform Task 29- Thanks for the reply
I will read more about the it from the Energy thread. Thanks for the reply...
That is the ROM I started having issues with.
OCT.8 Cookie Rom- Flashed and just like normal everything was fine. Drove out on a job for work and everything was good, later got back to my shop in and looked at the phone and it was stuck on the other city,kinda like it hadnt updated since. Tried to update and it just would time out? So I Hard reset the phone and it never loaded the My Location... Full signal indoors and out.
One of the guys I work with has a TP2 as well and he asked me if google was working. I tried to locate me on the map and it says "Your location is temporary not avial." When I try to update the weather from the tab it says "No updates are avail."
I dont know? Im downloading the new ATT ROM now and will, see what it does.
I was told that it will update my radio.
Ive never flashed my radio, and dont know much about it or what exactly it does to upgrade it. I am going to try to read more tonight when I get off work.
Thanks, If your have any inputs/questions I will get back ASAP...

Dont know?
Well the new ATT ROM is on the phone working fine...? As soon as it booted the weather on the Sense popped up with my city... I cant figure out why other roms arent working.
Im going to flash again to Energy soon... Maybe tonight or tomarrow; Battery is dead and have to let it charge. Besides Ive flashed some many times im tired of messing with it.
If anyone has any ideas on what my issue may be please help.
Thanks-

The stock ROM works fine because it does all the work for you. It preforms a task29 as part of the process. If you don't know what that is, it's a tool that erases and formats the internal memory of the device. It also flashes the radio and the ROM in the same program. Basically, all of the things you needed to do on a custom ROM, it does for you on the stock ROM.
BEFORE putting another ROM on your device, preform a task29 (search for it in the Rhodium ROM dev section), then flash the ROM. After that, read the FAQ in post #6 of the Energy thread. If that doesn't answer your question, then ask about it in that thread.
BEFORE posting a question in the Energy thread, be sure to read the FAQ. There is a correct way to ask for help there.

IDK, This is wierd
I do know about task29 and perform it before every flash.
So Stock ROM V.2 was working on "My Location" and Google Map... So I was looking around for .Cabs to clean the Stock ROM up and noticed that ENERGY had posted some new ROMS and I downloaded one. I Task29'd and flashed to the new Energy ROM, No fix on Google and weather "My Location" still unable to update or even find my location...?
Task29'd and went back to Stock ROM V.2 and now I'm having the same issue with the stocker?
Does anyone know what could possibly causing this issue? I don't ever get into the Registry or anything. I just flash and go adding the basic .Cabs
I'm at a loss... I would really hate to replace the phone due to this. Everything else works fine it just seems to be a GPS issue...
Any help would be greatly apperciated.
Thanks in advance-- I hope

This to me would seem to indicate that it might be an issue with the cell towers and not your phone, if it works in some locations and not others. Its a pretty common issue, that's why its on the FAQs. For months, my phone would not retrieve the location information from the cell tower near my office, despite 4 bars of reception. But it works fine almost anywhere else. Next time you are driving to other locations, experiment and see if it works better in other towns.
The time out message for weather just means it can't get the weather info over the data connection, it doesn't refer to My Location. The HTC weather server has issues from time to time, so this may have nothing to do with your phone.

If you are running Energy ROM, then the solution to your My Location problem is listed in post #6 of that thread. The easiest solution is to simply disable 3G. My Location is determined from the Cell Towers, not the device. If this solution doesn't work for you, then that narrows the problem down to something you've installed on the device. Try the solutions listed first. If that doesn't work, install a program like Sprite Backup to create an image of your device so you don't loose anything. After backing up, flash the stock ROM and see if, without installing or changing anything, you have the same problem. If it's working like this, then install things one-by-one until you find the culprit.

Flashing the radio is super easy. If you've already flashed ROM, flashing the radio is basically the same process, except it only takes a several seconds. It updates the software on your phone that allows it to connect with the cell network. It resides on a separate part of the memory than the OS, so it usually is not affected by ROM flashes (and vice versa, flashing the radio does not affect the ROM). The newer official ATT ROM is an exception, where they packed the radio in with the ROM. So now your radio is updated to the newest ATT radio. Flashing custom Rhodium GSM ROMs from XDA won't affect the radio, unless specifically indicated otherwise (and I haven't seen any custom ROMs that do that).

There are a couple of custom ROMs that flash radio as well. I don't recall which, but be sure and look before flashing!

Thanks, good to know. Of course, we always read the ROM instructions thoroughly before flashing!

Narrowed Down...
Thanks to all that have helped so far...
Ok after reading the last few post I have somewhat narrowed down the issue.
Okay, Yesterday I flashed the New ATT ROM so I have the upgraded radio-
Discouraged after I lost the "My Location" with the stock ROM and its differences between Energy(I guess I got spoiled by it) I flashed back to a later version of Energy.
CajunFlavoredbob- Thanks for recommeneding me to try disabling 3G and see if it works. Well it did, I dropped to the Edge network full signal and it picked up pretty quick both on "My Location" Weather and Google... Switched back to 3G and issue came back.
So I read post#6 from the Energy forum and one user says for him he used
"FF ATT Nokia aGPS Settings" I am using something I think is similar to that it is "FF Google aGPS Settings Generic" but I guess its not work aswell as it should or at all? So I am going to try to find this other .Cab and install it and see if this works.
Somewhat narrowed down, with the issue but feel like I am getting somewhere
Thanks to all for help so far! I will keep you guys updated...

No luck...
Okay well I got 3 .Cabs from I believe Fone Fanatic and another one from this guy I work with and no luck?
Any other ideas on what I can do?

[Q] Flashed Incredible, lost all location services

Hello everyone,
I've been a lurker here for a bit. Some time ago I used Unrevoked, did something wrong installing the original FroYo update and screwed up my phone. I migrated to the DX in the meantime, but this weekend I wanted to return to the Inc. I successfully revived it after a lot of trial and error.
Now my issue: I have tried several ROMs including SkyRaider and Cyanogen, but my location service is not working. Not in Google maps, search, not for weather widgets, nothing.
I'm not sure if this is related, but I have tried a few different radios thinking that could be the issue, but its not. Also, I can only seem to get a working earpiece with the V1 radios.
Any ideas on how to get my Inc fully functional again?
Thanks.

Try the latest RUU. Short of a brick or hardware problem, that will fix anything.

Search for Bezerker7 and Ultimate get back to stock thread, that'll explain how to flash the RUU and get back to stock, see if location services work on stock 2.2 unrooted, and then you can re-root and flash ROMs.
EDIT: Here's the link.

I'm assuming that this phone is not activated as you have the DX? If its not activated and on the Verizon network then it can only get a location through GPS which may or may not be turned on. I would check to make sure your GPS is turned on in the settings, or use a toggle widget, and then try Google Maps again. I also think the weather widgets don't use GPS as the default and that may have to be set in their settings too. They get their location information from the carrier.

Thanks guys, this worked! Any clue why it happened in the first place?

If you didn't wipe data, then all sorts of crap will happen. You're lucky if you don't bootloop. I bootlooped even when I flashed the same rom and same version over again and didn't wipe data. So maybe it wasn't that.
Maybe it was just something left over, CWM not wiping or something like that.
I really hope it wasn't a hardware defect that subsided for a while

Another GPS Problem

Hey guys,
Don't shoot me, I've already done the research and still can't seem to find an answer. Regardless of ROM I can't get GPS to find any satellite's, fresh root, SR4.2, Synergy RC2, CM7 nightly, MIUI, Virtuous. I unrooted to see if it was a possible hardware issue, which it isn't as an unrooted phone gives me fast locks onto whatever sat is near. GPS Status shows nothing in the sky even after a A-GPS reset and download, although I know there's always at least 3 that are visible. I've tried clearing cache for any gps based app, tried running fresh rom installs instead of backups all with no luck. Any ideas guys?
Currently I'm running:
ROM - SR 4.2
Baseband - 2.15.00.07.28
Kernel - Stock Kernel from SR4.2 (2.6.32.17-g9a2fc16 htc-kernel[email protected] #1
PRL - 52341
HW Version - 0002
CWM - 3.0.0.7
HBoot - 0.92.0000
Radio - 2.15.00.07.28

Looks like I'm stuck going back to stock unrooted until I can get this fixed.

I'm having the exact same problem. Tried multiple roms and doing A-GPS resets. I'm not sure what else to try, anyone have any other ideas? May have to unroot for now so I can use GPS while traveling.

If you are in NY or other new 4g area it may be related to a problem others are having with AGPS upate VZW pushed. No ROM seems to work.

yep, it was an issue with New York. We drove to Boston on Sunday, I tried clearing my A-GPS in western Massachusetts and suddenly got a lock on GPS! Google maps then worked perfectly all the way to Boston.

Well there is no way I'm giving up root or custom roms, Google or Verizon need a better solution than that.

I actually fixed mine and never left NY, I dropped to stock then went back to SR 4.3 and haven't had a problem since, and I've flashed 3.0 roms and SR 4.3 multiple times with no problem. So if you're still having a problem unroot then reroot. It should fix it.

[Q] GPS position 260km wrong

Hey!
I looked everywhere to find a solution to my GPS that's not working and ended up with this thread, where crypted offers a scripted solution, including the agps solution, using the NTP servers.
I selected the Google Build and after a Restart, the GPS locked and I was happy!
But unfortunately, it locked 260km away from my position :-/
I know that some users already experienced similar problems, but I couldn't find any solution yet.
Did I miss something?

Hey!
These are two of the solutions I tried, first the scripted one (I actually wanted to post this link but I accidentally took an other ^^) and then the other one.
There was no change, I also think, that both describe a similar way to solve it.
Right now, I saw, that there are two gps.conf files, one in /etc/gps.conf and one in /system/etc/gps.conf, but I don't think that this is the problem..
BTW: Heres the GPS Status - there are no Satellites showing up, is this normal?

well, try with this too :
4. This works with ANY ROM unless the ROM has aGPS and/or GPS disabled in the code. This happens with CMx nightlies and some betas! I cannot fix this, neither can you.
9. CMx ROM users may not experience benefits from this patch. However, we have had good reports from CM users with one negative one. Remember to do all of the steps when flashing and the following notes are important too!
11. Reports show that certain ROM's including some CM builds require a modification in the build.prop. You need to change "ro.ril.def.agps.mode = 2" or "ro.ril.def.agps.mode = 0" to be "ro.ril.def.agps.mode = 1" in order for aGPS to properly function. Only do this IF YOU ARE HAVING PROBLEMS after attempting the standard patch.
the 11 one may get it to work ... ?

I tried that already (also tried different config layouts), but unfortunately, it changed nothing.
Isn't the aGPS just for finding the nearest satellites faster? So, it seems, that aGPS is finding the wrong position (maybe because of some NTP servers?) and that the normal gps still isn't even working (because I tried to get GPS running since I flashed CM7)..
Hmmm..

i guess it's not working, somehow, since you can't find ANY satellite
did you try any other rom, and did gps work when u were stock ?

^^
Yes, it worked on stock rom, and i believe it also did on another (maybe Mindhaxors ROM)
But I like CM very much and would prefer not having to change, these are like two worlds for me since I tried it out ;-)

I had the same issue, using CM7 nightly. I applied the patch and GPS was showing a fixed location far away from actual location. Then I tried a combination of using another app (GPS test instead of GPS status), calibration of compass (rotating in all three axes a cuple of times) and removal of AGPS data and GPS started to work in gps test as well as on google maps. After reboot however I was not able to reproduce it. Now I don't have any fix..I'll try it tomorrow, maybe I'll have more luck.

make nand backup and try full factory reset clean dalvik cache and stuff, and reflash... try it even with new sd card or just some clean one...
p.s. flash latest nightly, or 14th january one, since it's tested ;-)
Sent from my HTC Wildfire using xda premium

I have the same issue:
CM72, GPS fix various methods tried out as in the topics linked, get "too" fast fix within minuted but around 400km away ;-( Any idea what else could be done???

Yes. Wait for sat locks and position update the first time and try not to get bored and quit. It well find you eventually and subsequent location updates will be faster...Might take 10 min or so.

I also have the same kind of prolem.
I tried every solution adviced but my gps is stuck to 46°59.999N and 3°59.999E.
i am with cm 7.2 and my gps workswhen i install a stock rom.
thank u in advance

I think I might be having the same problem, in my case after applying GPS patches the location returned by GPS was constant (and far away from my actual location). I am yet to understand and fix it, but I think I'm getting closer
UPDATE @estantor - yep I'm having the same issue, the GPS is either stuck at exactly the same coordinates, or lately it stopped locking on to the satellites

those are the exact coordinates where my CM72 GPS is also stuck, in the middle of nowhere in France.
Really strange, I wonder if flashing a more recent CM72 update might help?
UPDATE: DId a new flash with CM72 RC0, applied the fix and now its fast and correct ;-)!!!

did you install the latest nighly build? i'm still stuck :-/
which fix exactly did you apply?
Edit: GPS is working after I installed m1ndh4x0rs ROM where it worked before and reverting to my previous backup (CM7) it still shows the wrong location, though, when GPS has a weak or no signal

[Q] GPS Not working

Hi All,
i sometimes use a GPS tracking app for when im out on my bike to track miles and stuff, last week for some reason it didnt work, then when i tried to use navigation a message across the bottom said something like SEARCHING FOR GPS and never changes or locks onto my position.
i havent changed anything that i can remember only installed new apps,
my phone is rooted and ive tried several new roms but none of them solve the GPS problem i have, ive read up and tried several solutions using apps to reset GPS and a patch that changed the GPS.conf file but to no avail.
could it have anything to do with an outdated radio ?? the details of my phone are
Rom SVHD1.61
Android 4.0.4
Sense 4.1
Baseband 12.56.60.25U_26.10.04.03_M
i know the radio version is the last part of the baseband and there is a newer one listed in this thread
http://forum.xda-developers.com/showthread.php?t=877295
the nearest to mine is dated 23rd June 2011 but the listed one has no letter U in the middle.
could someone please advise which radio will be safe to use as i dont want to brick my handset, and can i flash it using CWM as a zip like i do the roms or do i have to do it another way
thanks in advance

I had the same problem as you, and I have tested some roms wotihout succes... I have also tried to flash a new radio, I did it two days ago and it also didn´t improve my gps so I still without it... the only thing that could say to you is that there is a post that show you how to improve the gps but it is by solding under the flash of the camera and it is hardware so i am not going to try it
good luck

since posrting, ive tried several things to fix this, still with no success,
ive tried several different roms including a stock rom but none woked.
ive update the radio to a newer one and still nothing
i removed the flash cover ad tested with multimeter and it seems to be ok,
i attached a piece of wire to the contacts on the phone and managed to get GPS fix on 2 satelites so bought a new cover but no fix,
as mentioned above i soldered another piece of wire inside underneath the flash cover to the contacts but now i dont get any GPS, with the cover on or off, guess its broken.
can the GPS board be tested in anyway or replaced, ive searched google but cant seem to find anything so im guessing its part of the main board
im in the UK if anyone knows that i could get it fixed.
cheers
