GPS Cant get fix w/newest cyan roms/what are best alternative radiis?

In the recent cyanogen roms since 4.19 which required flashing with the htc radio my gps has stopped getting fixes. I am limited to only cell tower location. Maybe this is a radio issue? If so what is the best radio alternative which will work with cyanogen roms? I need my gps back. Thanks.

I just tested gps on my dream with cyan 4.2.1 on top of the htc flash. Working with no problems, even indoors. If you don't get any better tips, I would suggest installing again, and this time wipe ext3 partition in addition to wiping, and don't restore anything from backup for root users etc. before you check the GPS.

Hi
This may not be a tip, but i had the same problems when i upgraded rom, I had copilot and Ndive that worked prior, But stopped after urgrading rom to CYAN 4.1.999
Only solution i found was to try other alternatives, the only one i got to work flawlessly was Sygic mobile maps 9 V7.71, gets a fix almost immediatley and works Perfecto.
Hope this helps

I have the exact same problem!
I flashed cyan 4.21 and stopped getting GPS fix. I wiped, wiped ext3 and installed enomther AOSP 1.6 without the expansion pack. I can't get a gps fix anyway...

Christ, thats an ignorant post
Cyanogen does not "mess up basic functionality", 99.9% of people running his roms have no such problems, myself included. It was probably something you missed or did wrong in the process. Did you follow the steps in his first post carefully, it is a more convoluted process coming from 4.1.11 because of the changes required by Google. In any case, rooting and installing custom roms has its risks and you chose to accept those risks, stop trying to blame someone else when it goes wrong. Take some responsibility, be constructive and try to find a solution instead of crying about it.
Incidentally, the reason Google had an issue with cyanogen was, completely legitimately, because his roms included some of their closed source apps (mail, youtube, market etc) hence why his new roms do not include those and Google are fine with him now. Try reading about it before you shoot your mouth off

I'm trying to work out the problem right now. I wiped again and installed another rom - not cyanogen. The problem is still here. It seems to be a problem that not only I have. It's quite possible that I, and others having the same issue, haven't followed the instructions correctly or did something else wrong.

Try flashing the radio

Well, seeing as my GPS just got a fix indoors with Cyanogen's 4.2.2, I think the problem is with you.
Now, without posting what you have done to get your phone to the state it is in now, how in the world can we help figure out what went wrong? This really seems like an isolated incident, and obviously not one that is suggestive of Cyanogen's rom being faulty (pretty damn insulting of you to blame him) since you have the problem even after flashing a rom that you give so much praise to for being 'stable'.
So..... how about you reconsider what you might have done to your phone, and try some troubleshooting...
1. When I am having issues with my GPS, sometimes I find it helps to disable GPS (both wireless and sat), reboot my phone, re-enable them, and try again to get a fix.
2. Use GPS Status2 to see if it is connecting to any sats at all.
See what happens... Who knows, maybe there is something wrong with your phone (ever imagine that?).
Not trying to be rude, or bash you, but you were pretty rude and bashing towards Cyanogen, and then you said you had the problem with someone else's rom too...

First off. I have tried both steps you suggested.
With gps status I can see 4-5 satelites and the lower right of the display says 0 sats. So I can't get fix, the gps itself works. Could be a problem with gps.cfg, I'm going to look at it now.
The issue occured right after I flashed cyanogen 4.2.1 stable. Even afer wiping entirely and flashing another rom I have the same issue, So I suppose that that the problem might be radio related. I actually consider there might be a problem with the phone, but a user who started this thread also had similar problem after going to cyanogen build. Maybe he did the same mistake as I did. Many times I have installed roms and had no issues while others had them - sometimes they occur sometimes they dont - depending on what spl/radio you are on, even what network you are on and what ROM you are coming from. Sorry for being that rude, I realize that now...

We all get upset when things don't work that we expect to, my suggestion about that is to go back and clean up your posts before Cyanogen reads them (hopefully) so as to avoid pissing him off.. He has given us so much, and we don't want to alienate him on XDA...
Anyway, about seeing satellites but not getting a fix, have you tried re-flashing the radio?
You said you have wiped, and flashed two different ROMS. The possibility of it still being a software issue are slim (but still there), if the radio doesn't help... it just may be a hardware thing.
I have never had mine get locks on satellites and not lock-in my position.

I know this stuff has been mentioned, but here is your basic troubleshooting process. Complicated, I know. Shouldn't take all day.
Download GPSStatus2 from the market and check to see if it is connecting to any satellites at all.
a) Go outside, away from buildings and trees, and open GPSStatus2. If it connects to 1 satellite, your receiver is working and it's probably some fluke of atmospheric interference (rain, dust, clouds, temperature, vapor, fog all affect microwave transmission; even air quality) that it can't connect to more. Try some different areas with different weather.
b) If it connects to zero, reinstall radio image from the link a few posts up.
c) Still no luck, go all the way back to stock firmware (flash OriginalSPL if you have DangerSPL installed, then RC29) and let it update to Donut, try again.
d) If it's still not working, your GPS happened to randomly die or something. Call T-Mobile cause you need a warranty replacement. They will send you a new phone, you send the old one back.

You know... if you are only trying google maps, try downloading some alternatives. One off the top of my head is RMaps.

I'm flashing the radio now. I have tried the other steps. I tried to get a fix from different locations, now I'm in the mountains and the device has a clear view to the north, where most sattelites are supposed to be... Yes it could be a hardware issue. As you can see another userr ATINsa, who started the topic has the same issue.

still problems
I don't know why you are attacking that guy. There is a problem. I had it on my old dream which was just stolen and replaced. And now I have it with the replacement. Prior to 4.19 and the radio you had to flash to keep cyan cool with google I had no problems. Google tracks, my maps editor, and google maps have a problem. When using wifi can sometimes connect more. The old cyan roms worked fined. Please don't try to explain to me how to use a gps. I have reflashed and redormatted. This has reccured with all roms since I had to replacwe the radio with the one required for him to be cool with google.
So the quesstion is, what other radios are the newest and will work with gps and cyanogens newest rom?
There are 2 people in this thread with the same prob. A third says google maps didn't work but anothewr gps program did. I have experianced this with2 googlde dev dreams. There is a problem and its not a user problem.

Something like this really sounds like a hardware issue. I don't mess around with the GPS code in my ROMs.

The thing is, the radio that is flashed with the HTC system image, should be the same radio that you were already running on your phone. I don't think that has been changed since 1.5 came out.
And the problem with your theory of this being more than just an isolated incident is this: most people aren't experiencing this problem, only a handful (two or three people here or there does not a system problem make).

I'm 26 years old and have had windows mobile devices and now I've been on android for about half an year. I have used linux back in school when most of the kids here, blindly defending cyanogen were toddlers. I didn't mean to attack cyanogen or whoever else. It's just that the problem is with at least 2 or 3 people and maybe more. The right thing to do is to calm down and try to go back to a state which works. I have reflashed radio and gone to AOSP donut build. Still no luck. When you wipe you wipe /data and /cache right? What about /system ? I bet it's some of the libraries that have something to do with controlling GPS hardware, which remains after a wipe. It would be a nice idea to flash the SPL again. It will probaby clean things up. This is the next thing I'm going to try. It's a good time for someone with better knowledge of how android works step up and give any other ideas.
For now try :
Flash SPL again (whatever SPL you are using)
Flash Radio (latest one from htc developer site)
Flash some basic rom, like TMO cupcake or donut and let's see of it works. That's what I'm trying to do now. If this doesn't help, we might try the proposed reverting to stock spl and RC29.

If you wipe it wipes /data, if you flash a new rom it "wipes" (it really formats) /system and /cache. Nothing is left behind on /system...

Ok. I fixed the issue. I'm on danger SPL , newest radio etc...
I reflashed radio (as adviced above). Prior reflashing the radio wiped and installed enomther AOSP+ADP 1.6, with exp pack 2.11.
After that installed an app from market called GPS TEST (Don't know if it had something to do with GPS being fixed)
It detected 5 satelites right by the window indoors. Then Google maps found my location.

well if you tried another rom and its still there .. then the problem might lie with your phone and not the roms you installing .... is anyone else around you with a G1 not getting gps location also ?

[Q] bell galaxy s UGJG9 vs. UGJH2 differences

Apparently they released the JH2 again but including a SPL fix, so people already on JH2 will need to flash back to JG8 or something, then flash forward to JH2 again to get the new SPL fix

I got JH2 the other day. Yesterday my phone was going retarded, freezing and losing signal when it never had before. Seemed ok last night and today though I haven't spent much time with it today.
GPS was totally out of whack last night, sitting still and my location was jumping all over the place. Google navigation is unusable. Checked compass in GPS essentials and it was fine but in nav it just spins around and can't get it right.
Youtube widget changed. Now shows most viewed on the main bar but video and search buttons are not functioning properly. Right now it only shows the search button. If I search or launch youtube then go back the video button will be there but neither thet nor the search button will work. Wish I had just left it alone.

did you get the update with the spl fix?
and was your 3 button mode working for you before?
if not does it work with the new update?
lol so many questions... and thanks for the replies and the update on the firmware.

Just update dude. Everyone is experiencing various issues regardless of the firmware. I run 3 to 4 times a week using endomondo and the GPS tracks my route almost flawlessly. A few hitches here and there but nothing horrible.
My 3 button combo wasn't working at all and I was already on JH2. Had to do the registry trick to get Kies to flash the new JH2 on my phone and now it works. Upgrading to the new JH2 is the best choice to make, especially if you have plans on using a few mods.
I highly recommend the battery mod available on this forum after you upgrade. The SGS stock battery indicator is horrible and inaccurate, and I rather not waste my homescreen space on a battery widget.

Ya, did the update a few days ago. Three buttons work now and my gps doesnt think im in japan anymore (ya it was that bad) anyway definitely worth the update.
Sent from my GT-I9000M using XDA App

My 3 button mode worked before the update, I haven't tried it since. I haven't rooted and not sure yet if I will, will see how official 2.2 goes first.
Still losing signal though. Yesterday the girlfriend tried to call me and said she either got a busy signal (WTF) or it just went straight to voicemail.
Today I tried to make a call and had to redial two or three times because it kept losing signal. Def a problem with the phone and not anything to do with reception in my area. Only phone calls though, never lose signal when using data or market ect.

Guys, I'm a bit dense on this subject so please be kind.
I have JH2 on my Galaxy. I can't remember if I updated to this version via Kies.
So far, the 3-button recovery problem has not affected me. I haven't rooted Android (since I don't need SU rights), I haven't yet unlocked the phone (no need) and I haven't attempted any Android system updates. I guess I could be called an average user. I haven't tested the 3-button issue.
What circumstances could arise down the road, which would make it necessary for me to do a 3-button recovery? In other words, is this a problem which could affect all Galaxy owners?
Thanks.

I updated to JH2 prior to the SPL fix inclusion and found it to be better than JG9...smoother and less lag issues. Just make sure to backup everything.

My phone is still on jg9. It never had the three button issue it always worked for me. If I upgrade to jh2 how will this affect me?

I havent been able to update to JH2 from JG9 (trying to use kies but thats a prize in itself) but I have in the past gotten where I would try to call, and as the call dropped while still dialing it would tell me the radio is off. Or it would tell me im in airplane mode etc.
Now for the last 24 hrs I have yet to be able to make a call, although datta and texting works perfectly fine, every time I make a call it says my radio is off. And the same problem when someone calls, they are lucky if they get a fast busy signal.
Im talking with bell to get a replacement in store, if not I have a 'insurance' plan that'll give me a loaner etc while they ship it out.
Any update on whether your phone is still dropping into Flight mode?

[Q] Lost stable WiFi after updates, can't get it back

Hello everyone! This is my 3rd day of tinkering with the phone and since I can't handle it I'm asking for help. I'm a noob who read a lot, tried and apparently messed up.
I bought a new HTC One from T-Mobile in Poland, branded with CID T-MOB101 and Hboot 1.44. Everything worked fine but the phone still had Android 4.1.2 and no update available. I decided to get rid of the brand and get international stock version to be able to receive OTAs. I unlocked bootloader with htcdev.com, installed TWRP 2.6.3.3, achieved s-off using revone, changed CID to HTC___001 and used RUU_M7_UL_JB_50_HTC_Europe_1.28.401.7_Radio_4A.13.3231.27_10.31.1131.05_release_310878_signed . My phone did not see OTA so I applied updates manually in following order:
OTA_M7_UL_JB_50_HTC_Europe_1.29.401.12-1.28.401.7_release_315849_signedp7vl8dqsvls0h1t0.zip
OTA_M7_UL_JB_50_S_HTC_Europe_2.24.401.1-1.29.401.12_P2_release_324936_signedma8j1sa3e2o09s35.zip
OTA M7 UL JB 50 S HTC Europe 2.24.401.8-2.24.401.1 Release 331108tottoh71qygw07hf
OTA M7 UL JB43 SENSE55 MR HTC Europe 3.62.401.1-2.24.401.8 Release 338160gxmo5sd9337kadux
After each OTA i tried to look for updates in phone's settings and found only two little updates (few MBs) that did not lead to bigger ones; I believe it was after first and third OTA.
After all this I started having WiFi issues. The phone stayed connected to my WiFi the whole time but after few minutes pages would not load, games would not connect. Resetting the connection would help for another few minutes (or less). Factory reset seemed to help a bit, the WiFi was able to keep the connection yet it 'paused' from time to time. By 'pause' I mean lose the connection for a second and regain right after, e.g. I could connect to games such as Hay Day, but after a ~minute I would lose the connection and have to reconnect (in game, without touching phone's settings) and redo last X seconds of game.
Because of that I went and applied ARHD 31.6 custom rom and hoped for the best. The situation remained the same so I flashed ARHD 41.0, yet the problem still remains.
In the end I downgraded my Hboot so it goes back to 1.44 and used the RUU I used the first time, after that I changed CID back to T-MOB101 and applied my full backup I saved by booting (prior to flashing) TWRP before I changed anything in the phone.
I did full wipe every time I changed the system and I did factory reset multiple times.
As of now I am on my backup with
Android 4.1.2
Version 1.29.111.16 CL175271 release-keys
Radio 4A.13.3231.27_10.31.1131.05L
and my WiFi is unstable. I can browse internet, watch YouTube or do things like that, yet I cant play games requiring constant internet connection, such as Hay Day.
So my question is: What do I do to get it to work as it used to at the beginning? I would prefer having the newest Android version, but at this point I simply need a working phone so if anyone has a solution that would work on my current system or by flashing a new one I will be extremely grateful.

I've been having the same issue. Thought it was just me because I've looked for a solution ever since the Jelly Bean update. Mine is a Sprint One and worked perfect with the original firmware. Once updated wifi connected and would randomly drop for a few seconds and reconnect. I've noticed it's router specific. I had a Linksys wrt160 that had a problem at home, but at the office the Cisco E2500 works fine. I swapped my home out with an Asus RT-N12 that has the problem too, but not as bad. Was hoping KitKat would fix the issue, but it didn't. I've worked with HTC support for a while and they said the new rom's have updated wifi drivers so there must be some compatibility issue with it.
Think the best bet is a custom rom that has all the new kitkat features but the old wifi (and BT since the new one doesn't load the contacts in my car) drivers. Someday, I'll take the time to figure out making my own rom.

For now I'd recommend contacting HTC support and create a ticket so they know this problem is more widespread. That way all the new roms out there would have a working WIFI driver.

That's odd, when the first tier support couldn't figure it out they opened a ticket for me with higher level techs and they had me save a bunch of capture logs when the drops happen to email them. The carrier would be useless on this.

Modem crashing - bp-dumps

Hi guys.
Since last week I've been having an issue. My phone ramdomly looses signal for like 10 seconds and it generates a folder named "bd-dumps" with 3 archives on it: ramdump_modem_fw.bin, ramdump_modem_sw.bin and ramdump_smem.bin.
I didn't changed anything on the phone when the problem started. I was running LiquidSmooth ROM (Very nice, BTW), and started noticing this issue. In fact, I just noticed because my phone was lacking memory.
Now, I've been searching about this issue, but none of the solutions have worked for me. Some say is a bad SIM Card, others a bad network, but I am pretty sure that the issue is not about that.
Everytime that I turn on Data services, it happens. When data services are off, it doesn't.
Anybody has have this issue or have any idea what is this about? I attached some screenshots. Thanks!
Edit: I already changed ROMS, flashed Stock with RSD and flashed modem, but the problem still the same.

This is old.
http://forum.cyanogenmod.org/topic/79890-modem-crashes-on-102-nightly-28-sept/
Been happening on CM based roms since 10.2 or before, for me it will only crash while on H+, 2G won't crash. Stock rom doesn't crash. Already tried buying a new SIM card too.
Devs are either unaware/not willing to look into it/not capable of reproducing since it only seems to happen to certain unlucky people, probably related to some types of networks, since my crashes only occur while on certain regions of my country.
On the other hand, if anyone capable enough is willing to look into this, i'd glady crash my phone a thousand times to generate logcats, dumps or whatever is needed to debug this ****, after all, this is a dealbraker for CM, this is a phone after all.

On the other hand, if anyone capable enough is willing to look into this, i'd glady crash my phone a thousand times to generate logcats, dumps or whatever is needed to debug this ****, after all, this is a dealbraker for CM, this is a phone after all.

In my case, it does crash on Stock too. That's my problem. I flashed with RSD to Stock and still the same.
I have also tried other ROMs but the problem still the same. Any ideas?
Thanks

Modem still crashes for me on anything not based on stock 4.1.1 / 4.1.2 - That said, latest PAC jbbl 20140825 has had the least, but persistent and consistently crashing at the same intervals.
I came from stock 4.1.1 latest ota to 4.1.2MX then PAC jbbl 20140825, only got about 6-7% signal loss. Where as all other roms 4.2 4.3 and 4.4.x have been similar results in the 20-30% signal loss.
In your case, if you've not realized since, your modem might be bad hardware-wise. Since you say it was working and then started suddenly, even on stock. Stock I get 0% signal loss.

Xperia T (lt30p) Wifi problem

Hello. I have a certain problem which I would like to discuss here and ask for advice. I would really like if you could read everything and not just start with the "standard wifi fix" answers like "restart the phone" and such.
1. My problem: The problem that I face is that when I try to connect to a wifi network one out of the two following things happen:
-It connects and instantly disconnects
-It connects and after some time losses connection and says that it's out of range. This can happen after 5 seconds or 15 minutes/it's totally random.
I think that the first thing is connected to the second so let's just discuss the second.
2. Where and when: It happens everywhere and always. It happens at my home, at my school, even in Greece where I spend my vacations (just giving you some examples.).
3. Things I tried to fix my problem myself: I googled my problem for over 1 month now and found a lot of those "standard wifi fixes" I mentioned before. I checked all the settings on my phone for example avoid bad connections, disable wifi during sleep, battery saving etc. I did a factory reset 3 times, I even screwed with my router (even though it can't be my routers fault as it happens everywhere as stated and I am fairly educated in networking and setting up a router). And yes, I did update my phone to the latest version of android available which is 4.1 for me.
4. Contacting my operator: I contacted my operator and gave them a brief overview of my problem. So I went to the store and they sent it to the repair center/company that fixes Sony phones in my country (note: my phone is still under guarantee). After 2 weeks I got my phone back but they wrote that they didn't find the problem and just did a factory reset. After 1 day of usage, with the of course not repaired phone, I sent an very detailed email to the repair center explaining my problem and they told me to send it back again which I did. After a couple of days passed the repair center called me and the guy who was supposed to fix my phone told me that he did a factory reset yet again and that he isn't finding any problems with browsing the net with the phone.
5. Some important information: The phone had never been exposed to any water/fall damage in any kind of form, it was neither rooted/flashed or anything like that and there were no applications that could have messed up any files or settings (for example wifi fix apps and such). I am running the latest available firmware (checked with xperia update checker, sus and PC companion) which is 9.1.A.1.141 R1.
6. Some probably not so important information: A friend of mine which I meet quite often has the same phone but has an different operator is running 4.3 and has no problems with the phone what so ever. Also when I went to the center of my operator the guy that helped me tried to connect to the router he was literary 2 m away from and it instantly disconnected him saying "not in range".
7. Don't say those things as I already tried them without success:
-everything connected to wifi/network/battery saving settings on the phone (avoid bad connections, auto IP, Static/DHCP etc.)
-my router settings (channels, security etc.) - every other device works perfectly fine
-SIM card - calling, mobile data and such works fine
-apps - never had "wifi fix", battery saving or any kind of form of apps on the phone that would "improve" it's performance
So I am really desperate right now and would really appreciate if someone could help me.
EDIT: I forgot to mention that after some time after a couple of minutes it shows the network as being available again (but doesn't reconnect) or waits until I restart the phone before it let's me connect to it again.

Did you update OTA?
If I were you I'd flash a different ROM (different FTF) maybe a different version or a different region, and maybe even backup TA partition, unlock, root, and flash a different Stock ROM and/or a custom ROM (CM, Carbon, etc), and see if the problem persists.
If there still is a problem then it definitely is a phone (hardware) problem, especially considering other devices work on the same network you're attempting to connect to.

I updated using PC companion as soon as I got it.
I would love to try flashing it and using either the latest official unbranded rom for my phone or CM/omnirom but I still have one year of warranty left which I don't really want to void. But to be honest if I can't get to fix the phone in the next month or two I'll probably buy a Nexus 5 and flash the hell out of my xperia T.

When flashing a unbranded ftf with Flashtool you dont lose warranty, as far as I know.
If nothing helps with your issue, you could send the phone to Sony two more times and ask for a refund, should the problem persist. :good:

So if I understood you right flashing does not void my warranty because there is no need to root the phone which means as well that there is not need to unlock the bootloader? Side question, is this "global" or can my operator deny warranty because of an unbranded rom on the phone?

Flashing with Flashtool (the one here on xda, not Sony) is like updating via pc companion.
Just keep an ftf of your original operator firmware on your computer, should you need to revert for warranty purposes.
Flashtool leaves no traces on the device.

There isn't any Unbranded - Central Europe so should I just pick the Unbranded -Germany as there is no Unbranded - Slovenia? It doesn't make any difference anyways as far as I understand it.

I've backed up my TA partition, unlocked it, rooted it, changed ROMs, gone back to stock, relocked bootloader, and it's never left any trace of me having altered it, so if you do things properly, I don't see how you would lose the warranty. What they don't know can't hurt them

I'll be sure to try it as soon as I get my phone back from the repair center. If it doesn't fix my problem I'll just buy a Nexus 5 which should pretty much fix all my problems regarding updates too.
Thank you for the advice everyone.

I had the same problem on my Xperia V with firmware 9.1. Now that I switched to 9.2 the problem is even worse!
Sometimes I loose my connection and in the Wi-Fi list I only see 1 or 2 networks, where I normally see at least 10 networks. Then I reboot and everything is back to normal...
Could be a firmware problem. I don't know if it's possible to reload the Wi-Fi firmware without rebooting?

I've just found that when it starts to bug, I only see networks in the 5GHz band. Networks in the 2.4G band are not visible.
