GPS fix? AOKP maybe cm9 ics

First of all I'm on AOKP 715 m6. My gps was nonexistent even though it was good on earlier versions. I was running a modded vle radio which i don't remember the source. Anyways, i flashed tdj's modded vle radio in one of his threads and gps initial locked on in less than 5 mins. It then locks on in less than a min after that.
At first i thought it was the kernel, so i flashed different ones, but no changes. however the radio definitely fixed it for me on AOKP.
So to those with gps problems try flashing tdj's modded radios. Sorry for being lazy on my phone and not linking them.

This was discussed months ago. Its the basic reason modded radios were made. Apparently the RILS break GPS. So yes GPS won't work unless you flash one of the modded radios, as you found out by accident lol.

I am not using a modded radio I am using the one that came with the ics official update uvle1. And I am running AOKP M6 7-15. My GPS is the best it has ever been I get instant locks even indoors. And It is accurate too. I have also used other roms and had the same results.

yeah i remembered that discussion, and I flashed a modded radio and it worked for most ROMs. I was then really bothered that my uber great locking GPS was no more... I seriously thought I flashed TDJ's radio because I had a file with the same name in my sd card. So I was bummed and decided to test kernels because thats like testing 2 things at once lol. But yeah I ended up checking the md5 of the modded radio i had on my sd card and it turns out it wasn't the same. Must have gotten it from a different thread even though the file name was the same.
But yeah it's just a little reminder to those who have GPS problems, that even though you may think you have a perfectly working radio... you should just flash TDJ's radio mods just in case.

Just flashed TDJ's modded UCLE1 radio...still no luck with GPS

What do you guys mean when you say "breaks GPS"? I am trying to determine if my problem is similar to yours.
My problem is not really an issue with the GPS but an issue with Google Maps. When I use navigation from point A to point B, say Schaumburg to Chicago, it'll always speak directions as if it's going from point B to point A, although all the on-screen directions are correct.
I uninstalled the app and reinstalled, but have not yet tested to see if that fixed it.

Have any of you tried the agps fix for cm and aokp ROM?

I have. I don't know why, but running CM9, my GPS doesn't work no matter what. Maybe the GPS chip broke or something.

Yes this is what I have to do every time I flash a ROM and GPS breaks. I made a thread about it and there are also 2 more threads. Its a zip file you flash through cwm. Also people don't forget that if you're on cyanogenmod that you have to go into location services, GPS source and tick "use internal GPS". Or else GPS will barely work.

didn't know he had a ucle1 radio, he has a uvle1 radio though maybe try that one.
If it is the first time you're trying to lock on, it might take a while, you should turn off wifi and data while leaving your GPS on. Stand outside with it on for 5-10 mins or so, it should get a lock on. After that your GPS locks quicker the more frequent you use it.
I think a lot of people would expect GPS to lock on right away, this only happens if your phone has recent locks to the GPS. I find it best with wifi and data off and to just leave the gps on and google maps on.
btw i've tried the AGPS patch before, but if you have a crappy radio it still won't connect lol.

Here's the screenshot without data or wifi. This is inside my house. Notice the gps signal has a constant dot in the middle, i know for aokp this means i have locked on.probably the same for cm, not sure about tw, haven't been on that for a month.
Anyways it has went as low as 4m, so pretty good. This is without apply the patch.

Download GPS status. Its free in the market. Will tell you how many satellites you're locked onto just for kicks. 4m is very accurate.

[Q] Issues - UGH

I'm having some issues. I am on Incredible HD RLS 2, I haven't been able to get on WiFi and this isn't the only ROM where WiFi isn't working. It will just never connect. Well, I tried to install ICS Official global CM9 upon initial boot it said it couldn't read my SIM. I powered down pulled the SIM put it back in and put the phone back together and then I couldn't get any service. No matter what I did I have no service.
Yes I followed all the instructions, wiped everything, flashed the proper gapps and the kernel.
Since that didn't work I went back to my nand and still no service. Anyone have any suggestions?? Please help

On global cm9 rum through setup and change network mode to cdma/evdo becuz it defaults to gsm
I'm so fresh you can suck my nits...

Will give it a shot, thanks.

Awesome, got service back, but WiFi is still not working. It just forever searches and never connects to a network. Anyone have any ideas?

This happens to me sometimes and restarting my router usually clears it up, not sure if you have tried that, just throwing it out there.

I can't reset the router, I'm on a college campus. I have the latest firmware and radios,switched out rom after Rom and still WiFi doesn't work. Any other suggestions?

Still having 3g issues on cm10 12/07

I have read the countless posts on the 3g issues, but when I try to access *#*#4636#*#* and change to wcdma only or preferred it won't stay the option just instantly changes back to CDMA and won't stick.
I was on paranoid android and flashed the cm10.1 12/08 nightly hoping the fix would work but it hasn't really. I read of a flashable fix and was hoping to get that but the link is down. Not really sure what to do at this point and I don't want to go back to touch wiz
Sent from my SPH-L710 using xda app-developers app

Not sure wat 3g issues u speak of... 3g should be the least of ur concerns on cm10. Changing the settings in *#*#4636#*#* is temporary. Use the network selection mode under system settings in cm10. Ur problem is most likely not from 3g but from the hand off from 3g to (ehrpd) to lte and any combination of the above. It is a known issue even if ur not in a full lte covered area yet. The APN is not configured properly. http://forum.xda-developers.com/showthread.php?p=35205882.

And I'm pretty sure there's an apn commit being entered in the next nightly that addresses the problem
Sent from my SPH-L710 using Tapatalk 2

As a user the problem manifests itself as me not being able to get 3g back unless I reboot so that's why I called it a 3g issue, sorry for not using the correct jargon. But thanks for the link.
The zip in that link worked temporarily but now I'm back to the same issues but worse because I completely lose all radios a few times a minute, except WIFI when lte is off in settings. When lte/cdma is selected in settings I have the same issues as before.
I think at this point I'm just going back to a touch wiz Rom it's not worth the missed calls and text messages to be on an awesome Rom. When my phone came back on from the fix i had like five text messages pop up from last night. And now I'm always just going to winner what I missed. I heard this bug mainly affects non touch wiz roms

No data connection after flashing a new ROM? Look here for fix.

I experienced the problem of no data connection after flashing a new rom on my Optimus G. The phone needs to be reprogrammed, updating your PRL and Profile will NOT help. You must dial ##72786# this will start the handsfree activation and your phone will reboot a few times. It may take a few seconds in between steps of the activation and it will seem like nothing is happening. Just be patient and wait for everything to complete. When it is finished your phone's data connection will be working properly.

Some history,
I've been running Imperium and stockishv1 and v2 for a few days. I've made a couple backups along the way. About an hour ago I lost data. The phone works and makes calls, but my data is dead.
I've tried update profile and prl, and all I get is" Network error" I've tried this many times throughout all these steps.
I've restored backups, pre-Imperium and Stockishv1 with the same results.
I tried the procedure in this thread and still nothing.
Anybody have any other ideas? Would LGNPST restore the phones modem?

You guys need to read this. I am going to open an LGOG Issues thread but need to grab some food first.

I did, and responded in your ROM thread. Thanks
edit: Now all of a sudden data is working. BTW when my data wasn't working it still showed a flashing 3G. Sometimes. Both arrows on and off
edit 2: Also when data wasn't working, It kept wanting to roam.

saw the same thing on stock as well

Related:
I killed the connection optimizer while I was at work because I can't use work's wifi and listen to my icecast station I setup.
This killed my data connection and immediately put my phone into roaming. I rebooted like three times and finally my data came back (i also updated the PRL and the Profile, not sure which fixed it but something did)
From the things you guys speak of, I would guess the same issue is at hand.
ALSO: Stock rooted rom (non-deodex pure stock with bloatware frozen with titanium)

Try the G2 thread, I'm sure if you post in the exact same section over there you might have better results. General answer is that it is probably APN settings. Find an app, enter them, set it, and reboot (might not need to reboot).

[Q] 3g on 4.3 ROM won't connect

Currently on Goodness Noteworthy 1.0.8 (4 1.2).
I've tried the latest Illusion & PA 4.3 ROMs. I liked them, both, very much.
The problem is I cannot get a 3g connection with either ROM. I live in a non-LTE area so this is a deal breaker.
It's not my location because I have fantastic 3g on Goodness in the same places.
I tried updating PRL & profile, before flashing, still no connection.
I've seen others are having this problem with those ROMs as well.
I was thinking I might need to flash a 4.2 ROM, that has a good 3g connection, before moving up to 4.3 but now I see people have had the same issue in 4.2.
Any suggestions?
Sent from my SPH-L900 using xda premium

I'm currently running PA 3.99 and 3g and 4g seems spotty. Even wifi is not as reliable. PA 3.99 is my first flashed rom and have been a daily for me...but not sure how much longer i can take it. Thinking about flashing a 4.2.2 rom.

Did you ever get resolution on this? I'm having a very similar issue with AOKP's latest 4.3 rom. I've also noticed that sometimes I can get service if I reboot a few times, but that's a PITA when I'm just trying to listen to streaming music in the car.

Yeah. I messed around with changing the APN but still no luck. I guess I'll wait for an update to AOKP like you did with PA. At least my wifi works. Thanks!

I just deleted the "Sprint" APN and it behaves a lot better (not perfect). Need to test more APN configs to try and figure it all out.

The only way I managed to fix this was to flash an older version of Aosp Rom. I'm using cm10.2 and I clean flashed back to a 9/25 nightly.
