Is it just me or are all the radio's simply awful ?

Tried and tried and tried to get a decent radio, none of them appear to work well at all, I have used co pilot since i had it on my HTC Hero (which was also a little iffy too) i tried it today and i didn't even get a gps signal at all, the stock radio always got a lock within about 10 - 20 seconds,I have Core droid running at the moment (froyo with sense) which is a fantastic rom (build number 1.84.661.1) I am using the radio from the radio thread which matches my build number, I am on Orange uk and previous to having a a custom radio It was always getting a gps lock (on both maps and co pilot), mobile data was usually always on H and i never lost a call, wifi has always worked regardless of what radio i have had (on either phone) and still does, battery life is always poor but i think that goes with the territory of having a dhd, i'm presently overclocked to a max of 1.2ghz, usually 1152mhz, which i believe is using an undervolted kernel.
So I know that there is always a shadow of doubt of whether a specific radio will work on any given phone but surely there must be someone in england (london if pos) who has a working radio which i could know about, it would be a great help and would possibly help more than one person, maybe a thread about a specific rom, kernel, build number, location and Radio and how / if it has helped you, would be a good start, there might be a pattern showing as to what works and what doesn't.
Any help would be well appreciated.
Cheers.

Why don't you try to use the radio which you had when it still worked (the stock one)? If you're using a case it might also weaken your gps signal.

No problems with radio here mate.
I am using LeeDrOid v2.2.2 with radio 12.28e.60.140fU_26.04.02.17_M2 with Kernel LeeDrOid-Ace-V2.2.8
Wifi signal is strong enough to be catched 2 floors away from my router.
GPS fix in CoPilot is within 20-30 secs.
Bluetooth works and 3G works great as well.

No radio / GPS problems here. Quite the opposite actually.
Try Fasterfix from the Market. CoreDroid may still comes with North American GPS config file and Fasterfix can change it to Europe

Thank you to everyone for answering, ill try what you both suggested, I wasn't aware of the gps being changed, so yep thanks a lot, ill try them all and report back.
Cheers.

Would your lack of signal coincide with using a case?
It seems that the Case Mate Barely There (metallic silver) does a very good job of shielding the phone from the GPS signal

I do use a case but its the chunky one by case mate, definitely there lol, Ive had it for a while, never really had any problems, but ill try without it anyway. Surely a metal roof of aa car would act more like a shield than a plastic and rubber case tho? Oh and I went for the radio suggested on this thread and I seem to be getting better results. Will try again on the wway to work tomorrow.

But you don't have the phone attached to the roof, do you? There's always somekind of clear view from the phone to the sky. I atleast notice a clear difference with the case off.

Hey OP, instead of using fasterfix, you might want to go to http://www.pool.ntp.org/ and check which servers are available in your country, then edit your gps.conf file (in system/etc) to reflect that as the one present now will probably say NTP_SERVER=europe.pool.ntp.org. It worked for me. You can use GPS status from the market to check how many satellites you get.

Im using radio 12.35d.60.140fP_26.08.03.07_M and having no problems with it in the UK

Isn't this what fasterfix does for you (need root)?
There is a UK option within the app.

Well yeah, but if you do it manually you can add the extra servers, like
NTP_SERVER=europe.pool.ntp.org
NTP_SERVER=0.europe.pool.ntp.org
NTP_SERVER=1.europe.pool.ntp.org
etc.
I'm not sure if fasterfix only adds one line or not, but at any rate you can get the job done without it, and chances are you will end up having to navigate to the directory to check gps.conf anyways, so might as well edit the file yourself.
There are also other things you can edit gps.conf with to adjust gps performance.

how do you edit the "gps.conf" file? I'm using ES File Explorer, and every time I add servers and then try to save it, it gives me an error and won't keep the changes I made. Should I delete Faster Fix?

Because you need a file explorer with root access to alter system files I guess. I know that ES has a root option, I think it only works with cyanogen and hiapk roms, not sure though. I use Root explorer. It's not free, but I end up using it so often to move files around and edit them, so it's definitely worth it.

[Q] Nexus won't see GPS satellites

I've had the nexus toro (LTE) for 5 days now and have had issues with the GPS since the start. It simply says 'searching' all the time and will not lock. I've installed GPS status, and it shows that it rarely if every sees a satellite (one might pop up, be gray for a second, then disappear).
Here's a pic comparing my OG droid to the nexus right next to each other:

(sorry i'm not allowed to post links yet)
Anyone have any ideas? I've turned GPS on/off, reset the gps cache using GPS Status, and can't think of anything else.

I have the same problem gps locks less than 50% of the time.
Galaxy nexus s LTE.

Its the same on the GSM version. Not much you can do about it unfortunately.

I feel like a dolt because I chatted with Samsung support and they had me soft-restart which fixed the issue.

Don't; that is not a solution. On my Samsung Fascinate soft restarts would help get a lock on, but shortly after the GPS would lose connection to satellites.
Having to restart your phone every time you need to use GPS is a ridiculous inconvenience. This seems to be a major flaw in the chips / radios that Samsung chooses for GPS.

i get gps locks in 2-3 seconds.works fine.

I'm glad to see others are noticing this problem. I posted a thread in another forum complaining about this:
http://www.droidforums.net/forum/ga...ssions/189067-problem-nexus-locating-gps.html
Does anyone know if this is definitely a hardware issue? Is it possible that it's a bug in Google Maps that's causing the problem with ICS?

It doesn't have to be Google Maps it self. I have it in other apps as well which use the GPS.
Might be hardware, might not.

One of the main reasons I upgraded from the Galaxy S (fassy) was that it's GPS chip went from working not very well to not working at all. If I'm paying for a smart phone, I would like a to have GPS and maps.
So far I have not been disappointed with the GNex's GPS at all. Maybe I lucked out. Try downloading GPSfix from the market and see if that helps.

I have the exact same problem here in Sweden, went for a run and it would not lock on to any satellites at all during half an hour. Really disappointing, thinking of returning it due to this...
Has anybody found a solution to the problem maybe???

was having same problem
Hello fellow GNex users having the GPS issue.
I was having a GPS problem as well where when using Google Maps or Navigation, the GPS status would say 'searching for GPS' forever.. maybe after 10 minutes it would get a lock and operate normally after that.
I downloaded an app from the android market called GPS Test to try to get some better idea of what could be going on.
When I ran the app, I noticed my phone would pick up a few satellites (satellites in view) usually 4 or 5 satellites, but it would never use them, they would just appear as in view without being used for a location, and the GPS test app was never able to report my location. From within the GPS app settings I was able to clear aGPS and update aGPS, but the same behavior would reoccur where the satellites would be in view but would not be used for location.
I tried toggling Wi-Fi, clearing out other location methods, and even going into airplane mode to use GPS only, but same behavior.
What I finally did was clear aGPS once more and then immediately power off the phone, pull the battery, wait a couple minutes and then replace battery and power back on.
Upon going back into GPS test, I did an update aGPS, and then I started to immediately pick up satellites and use them for location. Toggling all the same data connectivity settings (Wi-Fi, location using towers, airplane mode etc) I was continuing to get the same positive response.
I have tried to use google maps and google navigation again and am getting near immediate GPS locks. Comparing this to my Nexus One, the lock is much faster and with about the same accuracy.
This seemed to solve my problem for now, I hope it might help anyone else.

subsonicbug got it right...
I had the same problem of never syncing GPS, I follow the suggested method and voilà 2 secs GPS sync...
You save my day
Thank you

My gnex was having similar issues, after reboot it would lock quickly, but after a while it would take forever and never lock
Been using this to reset / download agps and it helps a ton!
https://market.android.com/details?id=com.eclipsim.gpsstatus2

subsonicbug's method was the only thing that got my GPS back to usability after several very frustrating days during which my GNex could barely see two or three satellites (and not get a fix on any of them) even under an open cloudless sky.
He or she is clearly on to something...now let's hope that we (and by "we" I mean people way more knowledgeable than me) can figure out why a significant number of Galaxy Nexus devices get so far out of whack that only a soft GPS state reset followed by a battery pull can get GPS working again.

there's actually an easier way that doesn't involve a battery pull. download the app "gps status & toolbox", press menu, tools, "manage a-gps state", reset, after a soft reboot go back into the app, follow the same process but instead of pressing "reset" press "download" after the download you should be good to go. hope this helps!

FasterFix works for me, make sure you have busybox installed.

The unit I'm currently using says location unavailable after resets, pulls, wipes. Hardware problem? I do get intermittent flashes of use.

Here is a fix that may work. I had the same problem and this worked for me, got a gps lock with gmaps in less than a minute. I have the VZW GNex, rooted bootloader unlocked, works with any rom.
Conditions needed:
1. Phone needs to be rooted, I believe, if you have success with out root please share.
2.file explorer, I use root explorer
Now follow these steps:
1. Open root explorer, or any other file explorer
2. Navigate to /etc
3. Ensure the system is mounted r/w, if using root explorer press mount r/w
4. Open gps.conf with text editor
5. The first line will say NTP_SERVER=north-america.pool.ntp.org. Where it says north-america it could list a different continent depending on your location.
6. Edit this line by removing the north-america
7. It should now read NTP_SERVER=pool.ntp.org
8. Save the file and exit
Now open open any app requiring GPS and you should get an instant lock, or pretty close to instant.

hmm my issues seems sorta wiered too -.-

tracks seem always loosing lock and so does navigation and other tools

GPS workaround (applies to phones containing SiRFStar chipsets like SGH-I927)

I have been having the GPS problems that everyone have been complaining about.
Annoyed, I decided to google something regarding the GPS, and having narrowed
down the list of suspects, I decided to look in /system/etc and found "sirfgps . conf"
file to be the main interest: LNA_Enable was set to 1, thus the original problem.
I decided to try set it to 0, as well as Frequency_Aiding line to 1, and
since I am not on AT&T network, I set ATT_network to 0.
And I copied the well-know "gps . conf" file from another Android phone (try Samsung
Galaxy Precedent ROM zip - look into /system/etc then extract it and copy onto your
phone) to this phone. Waited for a while in GPS Status, then downloaded GPS aid -
it came up in less than a few minutes the next time I restarted GPS Status.
The files are down few posts - I have chose to post it to reduce the fingerworks somewhat. The reason for GPS lock failure is simple: I suspect three things, bad antenna placement, bad capacitor decoupling plans / noisy LNA and / or (gasp) the LNA chip simply doesn't exist. For the GPS to work, you're supposed to have clean 50-bit transponder data picked up from 1.85GHz radio (GPS band), however if you have rather noisy setup, the chance of accquiring the clean lock drops dramatically. This is certainly for the SGH-I927 (Samsung Galaxy Captivate Glide and even other phones are affected - you will never know unless you check). However, when I disabled the external LNA, the internal one, on the GPS transponder decoder die improve the quality of the lock due to the fact it operates off clean voltage rail, thus the shortened GPS lock time.

Here's the GPS configuration file I copied from Galaxy Precedent (USA GPS marker).
Unzip it with Zarchiver app (download from Google Play), then use ES Explorer
or your favorite root explorer, and set your firmware volume as writable
(Be sure you're rooted!) then copy the unzipped GPS config to /system/etc.
While you're at it, edit the sirfgps . conf file to the settings I posted.
(Frequency aiding seem to be optional, and would improve thing).

Tested this workaround again, it works. At first, it does take longer (160 seconds to GPS fix according to GPS status), but then I reloaded GPS status, the lock is accquired instantly (16 seconds).
There's difference between two same SGH-I927s, but still, it's even better than waiting for 15 minutes to get the first-time lock - this workaround I found out on my own did reduce the time to lock to 5 minutes max, then less than a minute on next lock.

EDIT:
Here's the text file of sirfgps.conf file (rename from sirfgps_conf.txt to sirfgps.conf if you are running any flavor of ICS ROM on SGH-I927),
It gives you an example of what I did for my phone. The GPS-related settings are the same for Gingerbread (check your sirfgps.conf in Gingerbread ROM against this one, they're similar).

I found out about my mind-absentness.. My apology... It is EXTERNAL_LNA, not ENABLE_LNA... :silly: My brain must have taken a vacation... :silly: Otherwise, the instruction is still correct. If gps.conf isn't working for you guys, try pull from another phone.

Hi Dr. Mario,
Last post here was in Sept so wondering what the latest advice is ?
I just flashed my Rogers SGH-i927R unlocked in Australia to the Stock rooted ATT ICS 4.0.4.
It all seems good except I'm not getting a GPS lock, previously on the Rogers 2.3 ROM I got a lock with 15 secs.

You can try the link above, and then copy the gps.conf into /system/etc manually, you can also rip the same file from Rogers Gingerbread then pop it onto your ICS ROM. I will also try to create the update zip that works (the one in link doesn't get along with the CWMR 5 / 6, thus extracting it and copy the file over manually).

Got the GPS to work with info from this thread and this other one:
http://forum.xda-developers.com/showthread.php?t=1239713
Essentially made the suggested changes to:
/etc/gps.conf
NTP_SERVER=0.oceania.pool.ntp.org [changed from: noth-america.pool.ntp.org]
/etc/sirfgps.conf
EXTERNAL_LNA=0 [changed from 1]
FREQUENCY_AIDING=1 [changed from 0]
ATT_NETWORK_OPERATOR=0 [changed from 1 since I'm not on AT&T]
Rebooted and ran GPS Test, once it found 8 satellites and locked onto 3 of them within a few minutes I then ran Google Maps while driving in the car and it stayed locked onto my position.
Coolio.

That's good.

Qmobile A6 Poor GPS Fixed

Qmobile A6 have Poor GPS because
1 ) Take long time for cold start
2) GPS crashes sometime during cold start, as GPS Beacon disappears but the App keep running.
The 1st issue regarding long cold start is fixed,
The reason was Mobile could only utilize GPS (StandAlone) and unable to Utilize Assited GPS because it is unable to connect to the Supl.Google.com Due to invalid SSL certificates at PATH /SYSTEM/ETC/SECURITY, i have tried various SSL certificates (SuplRootCert) but the output was same and counter productive.
Disappointed by google i experimented other SUPL servers as
#SUPL_HOST= glsupltls.glpals.com
#SUPL_HOST=www.spirent-lcs.com
#SUPL_HOST= supl.sonyerricson.com
some were working but slow but SUPL.NOKIA found best, and now using GPRS/WIFI connection my gps fix is less then 10 sec (skyfacing) once locked it will continue to be locked and you could use Sygic for Turn by turn navigation.
simply put the attached files at the path /system/etc/ of your mobile,
Note : The mobile should be rooted.
For Rooting use script Bin4ry.7z and follow steps at path given in the web link below, it will work both for A6 as well S2
http://forum.xda-developers.com/showthread.php?p=31545729
The Files are gps.txt and gpsconfig.txt: Plz rename these files to gps.conf and gpsconfig.xml before putting them at path.
You could use Es File Explorer for this purpose
Note : Plz take a backup copy of Orignal gps.conf and gpsconfig.xml before replacing them with new as a precautionary measure only.
After that reboot your phone and connect it to internet (wifi/gprs) and open GPS STATUS or GPS Test App (Sky facing) it will be have to fix within a few Seconds.
Note : In GPS Becon Disappears , restart App, this is a hardware problem which only occurs sometime during cold Start only.

I have bought Noir A6 a week before and I am disappointed to find the GPS issue. I have still not used your method. I am confused because with WI-FI it showed my location on Google maps immediately within few seconds. So that means that issue with A-GPS is only with GPRS data connection??.
I have tested Noir A6 and my old Huawei Ideos with GPS Test utility both indoor and outdoor without data connections. Here indoor means single story building.
In out door test Noir A6 acquired satellite more than 5 folds time it took to Huawei Ideos. Also the signal strength showed poor on Noir A6.
In indoor test Noir A6 completely failed to perform test after waiting for 15 minutes where as Huawei Immediately acquired satellites with reasonable sginal strength.
In nut shell it is clear that GPS CHIP used in Noir A6 is very inferior and it is insensitive to low signal that is why it takes ages to lock on to satellites where as Huawei Ideos acquire satellites immediately.
Unfortunately I can not post images now to show screen of GPS TEST

Well you will have to root mobile to get access to system files. I have rooted and change the files but I don't think that there
Is significant difference. Further I have used some utilities that directly modify .conf file but the problem is almost there. A6 uses inferior GPS chip set which is not sensitive and is cause of problem.

WiFi and Bluetooth won't turn on - Hardware defect or persist folder?

Hey all,
So I've been working on this for quite some hours now for two nights, but I'm done for and hope someone can give me clarity:
HTC One m9, running stock, latest update VDF Germany, Android 6.0.
Problem occured last week. I was using the phone quite extensively (yeah, tbh I was playing Pokemon Go... like a lot). With it being constantly on wifi/4g/GPS and all, charging it all the time, the battery also became quite warm.... And then while walking about it crashed and rebooted. I never had such a crash before tbh. After Reboot HTC Error Report even popped up and I also sent it. Then I found that the Bluetooth and Wifi Connections were off, which I usually both have activated all the time. And now I cannot turn them on anymore. No matter which shortcut is used. Wifi displays "error" after some minutes, while BT is just greyed out after triggering. Wifi Mac is showing with a 02:00:00:00:00 now as well.
So I did my research and performed quite some things, trying to get it fixed, because I am still not sure wether this is a Hardware or Software issue. A lot of people reported the issue at least for the wifi part. Less people reported it for both, wifi and BT, but I would guess that not too many people use BT regularly anyway. I found one person mentioning, that if both is not working it is most probably a hardware related issue. Which was my first thought exactly, thinking it overheated, something had gone loose internally and now the antenna is killed or at least not connected anymore.
As for the physical methods, I only tried the "whacking the back part of the device"-technique, which did not do anything. I haven't gone through "freezer" or "hair dryer" yet....
Some people were able to fix it via draining the battery and then restarting and draining again and what not.. but that all sounded weird to me.
I am still hoping it is software related so I went:
- Wifi Fix and Rescue App
- Unlock
- TWRP
- Root
- Reflashing stock
- numerous factory and network settings resets
Because I read about the /persist partition or folder and that it should contain wifi or mac address related info. Some guy had simply deleted those files and they were recreated upon reboot. But those files are not existing in my /persist folder (checked via Root Explorer - got the paid version) and I have Root - as stated above. Still that folder only lists:
\data
\display
\hlos_rfs
\lost+found
\rfs
\tee
I found a thread in google's cache of someone on how to recreate or fix that folder and contents, based on a nexus 5 however and that is probably not working on the HTC one m9 I was presuming.
So, what do you guys think?
Is there any way to get the wifi back to work? Would you say it even might be software related, looking at the persist partition/folder contents? Or am I totally wrong and the fact that BT AND Wifi are not working, rules everything else out and only leaves a Hardware Issue?
Looking forward to hearing your thoughts on this.
Thanks in advance!
- Arne

I'd bet a bollock its the hardware popped. Bluetooth and wifi are on the same board, probably the same rf chip. A local phone repair shop should ve able to fix it seeing as it's out of warranty.
