I was having GPS issues on EVERY rom I tried prior to remembering something I learned with my Epic 4g (Galaxy S).
I first Odin'd back to stock and when I did I Re-Partitioned and clicked Phone EFS Clear (this seemed to fix the GPS issue we were having on Epic) in Odin.
After this I flashed the EC09 modem with Heimdall (make sure you only use the modem.bin file when putting it in modem box).
Then I flashed CWM4 and then reflashed MIUI. I have since upgraded and downgraded MIUI multiple times and my gps always locks in less than 10seconds (make sure to use GPS Status to download GPS data on your first use).
The problem seems to lie with us flash addicts that like to try every single combo of every single rom and modem. The flashing and reflashing of modems seems to do something that screws with the GPS, I have since learned to find a modem that I like and stick with it, you can flash and reflash roms all day (in CWM) and it does not seem to effect the GPS (for me at least). I hope this helped people out.

JT's kernel update is in the latest CM7 nightlies. I had tried everything, but this is what finally made my GPS work!

+1 flashed a nightly with latest kernel and got solid gps lock within 10 sec
My GPS is awesome. Both TKSGB and leanKernel worked fine in getting mine to work better. Using TSM Resurrection (although I'll be switching to PWGB soon due to stability issues).
Is jt's kernel still having problems with wifi and 3g not working when turning the screen on? I got tired of toggling airplane mode last time I tried it.

I have bionix final rom. It seems my gps it's not working. I never can get a lock on. What is the problem? My location is Malaysia. I'm not using assisted. Please help.
Sent from my SGH-T959 using Tapatalk
click the link in my signature and in the first and second post I have the steps you need to take to have it work perfectly.
i had problems with bionix final, thought about flashing the ji2 gps, though, the ji6 gps was working fine in 1.9.1. but i ended up just flashing fusion anyway and gps is back to fully functional. i know that doesn't answer your question necessarily, but i posted in the final thread about the gps and never got an answer.
so try flashing a ji2 or ji6 gps (even though final is based on ji6) or flash fusion or 1.9/1.9.1.
In about phone, my base band is S700.0.5S.DK17
Why?

Because the modem flash failed, even though it said it didn't. Flash the DK28 modem using Odin again.

Redownload the modem. From different sources.
Sent from my Venomous Viper of an Epic in the Mile High City
I tried that, as well as the other options if it failed (which it never does).
Still DK17.
WTF
Try using going to DI18 with Odin, then using Firon's flashable dk28 to update. This is the original thread.
Try posting in the right section. Thanks
Sorry, I assumed this would be a dev issue.
In any case, nothing seems to work. I tried the above, when I took it back to stock configuration it still said DK17, and still does.
Everything seems to work OK, GPS, 4g, 3g phone data, everything.
What would this be affecting and are there any other things I can to to solve this?
Thanks,
BD
This happened with me as well. And this isn't my first time flashing a modem so i know I did it right. I've ran several dk28 roms already and everything works perfectly including gps. Im leaving it as it is.

Iam having the same problem has anyone figured out why our baseband won't change I have flashed over and over and my baseband is stuck on dk17. Thanks
I have been diligently searching for a thread to pop up along the lines of "GPS FIX" But I can't find any. I just wanna know if there is a definitive fix in the nightlies or not?
Not really. Some people are replacing their gps framework with one from an early nightly with generally working GPS. Other than that it seems different radios etc. Are having varying results.

This is the issue I had. I didnt mind replacing the gps.vision.so from Nightly #4 into the new Nightly's but now thats not even working on Nightly #17. It seems the GPS issue is getting progressively worse.
I'm on RC2 and was able to get my GPS working by flashing the latest AUS radio image (12.28h.60.140f_26.06.02.27). Before flashing it I was still on the old version from tmobile (12.21.60.09b_26.02.01.15). After flashing the AUS radio image my GPS started working but I was having problems with the reliability and speed of my data connection, even standing less than 800' from a T-mobile tower I was getting 1.5Mb/s download at best and it would only come in bursts. At that point I flashed the T-mobile image (12.28b.60.140e_26.03.02.26) from the OTA update and my data problems were fixed, started getting a steady connection and 4Mb/s+ download standing in the exact same spot, AND my GPS was still working. I've rebooted my phone several times since then I used the GPS for about 2 hours strait yesterday so it seems to be persistent and stable.
I have found that if I leave my GPS ON before I flash a new nightly or ROM, that it works fine. I have only ran into the GPS issue a few times but that was because I had it off before I flashed a new build. Never messed switching RADIOs or anything.
Here is what I have done to fix issues:
-If I flashed a new CM7 Gingerbread ROM without GPS ON prior to the flash, I usually go back to CM6 and turn GPS ON and then reflash the CM7 ROM and it works.
-Yesterday had a strange issue though, I went to Flash a new CM7 nightly and sure enough I forgot to leave GPS ON. So I went back to CM6 and tried to turn GPS on and it didn't work. So I then Flashed one of the MIUI ROMs and that still didn't work. So then I tried Flashing the newest Nightly from CM again and it worked very wierd.
That has been my experience with this GPS issue. Some how I have managed to fix it myself without too much trouble. Hopefully this helps people with these issues.

This worked for me also. I backed up RC2 with gps on, flashed MIUI, and then restored and blam it worked! thanks, I needed this so badly.
I had this problem for a while as well. Flashing CM7 #3 did the trick for me. I downloaded a copy of xboarder56's stock GB test ROM today and I have to say it works flawlessly! Smooth and fast and with working GPS.

So from the input I gather that nightlies have not yet fixed the problem. Since I don't need the GPS until the summer I guess I can wait a month or two before searching again...
Gps works fine for me.

Fixed the GPS issue on CM7 by upgrading the radio:
Vision_RADIO_12.28e.60.140f_26.04.02.17. It works just fine in the US.
http://www.megaupload.com/?d=OKYRIPQW
To flash radio you must have radio s-off using gfree.
http://forum.xda-developers.com/showthread.php?t=855764
You need to downgrade to the stock kernel or CM 6.1.0 for gfree to work.
I'm not sure what the problem is either, but I decided to leave the GPS/Navigation running over one night. When I woke up, the GPS fixed itself. I haven't had a problem since then.
use these basic steps to try and fix the gps:

But does it work when you turn GPS on/off/on after rebooting? My GPS works fine after flashing a new radio till I turn it off and back on again.

Okay folks, if somebody could bring my issue to the attention of anybody who knows what to do about it I would appreciate it.
My issue is twofold:
1)I'm still getting random reboots with RandomROM Thunderhawk 3.3 despite the posting on the thread that says (NO MORE REBOOTS) Is there anything that can be done about this?
2)I checked my baseband version and the modem is still EC05, is there a way to flash or ODIN an EI22 modem for this ROM without getting a black screen when the icons should come up? Could this also be what's causing the reboots?
Thanks for anybody's help that is willing to give it.
Are you using a custom theme? And you have to flash the stickied modem delta. If you are using a theme, I would blame that.
Sent from my ICS NookColor using Tapatalk
I was using thunderhawk too and I had some reboots but onlyyyyy on the lockmod version. When I flashed the regular one I had no problems at all
And for basband I would probably try this
Nandroid backup
Flash "ec05 to ei22" its somewhere in the development section I believe
Reboot
If that doesn't work then a fresh new start is what I would Recommend
Odin back to stock
Root
Install cwm
Flash "eco5 to ei22" modem
Flash thunderhawk 3.3 (without lockmod if you could live without it)
Sent from my SPH-D700 using XDA App
I got the EI22 modem here and flashed it in CWM and it worked well. Only problem I had with thunderhawk is the lockscreen mod, and I'm having data issues on wifi after the phone's been on a while.
I was ec05 but when I flashed the Thunderhawk and it changed to ei22. never had a problem. Got a wild hair up my butt to flash the shadow kernal 1.0.6. Never been happier. no reboots, wifi works perfect, and very responsive. running a live wall paper and still get awesome battery life. give it a try
I saw several posts from folks having some wifi-4g interaction problems...switching back and forth causing one or the other to fail...is that a common problem to all 3.3 users, or are most people not seeing it? I want to give this a try, but I use 4g (at work) and wifi (home) everyday, so I'd like to see how common that issue is. I'm currently on Mostly-stock with Nubernel's latest released kernel...
Sent from my SPH-D700 using XDA App
So...bummer. I guess I answered my own question...I installed Thunderhead 3.4.3 and sure enough... I have wifi and 4g problems. Seems like going back and forth between the two causes issues...had it fail going both ways today. On a positive...man, that ROM seems pretty nice and his new install process rocks...was seamless going from Mostly Stock...
Sent from my SPH-D700 using XDA App
You could always try a clean install with doing a factory data reset in CWM and wiping Dalvik, flash ROM, check to see if stuff works, then do an advanced data restore from your last nandroid. If you stll have problems then the best bet is to set everything up fresh after the clean install.

The deal with the wifi/4g issue is that 4g will show 0.0.0.0 for ip, baseband, and dns if used after wifi in most cases. This is on official releases of 3.3 and newer. If you turn off wifi, reboot, then turn on 4g it should work. This is oviously annoying. Random provided me with alpha builds of 3.4 and 4.0, and the issue was squashed for me. However, the issue still persists in 3.4.3 official release according to some reports. I have limited access to 4g and can only test on certain days.
Thunderhawk is in a transitional period right now, and 3.4.5 should be released today. Random is hopeful this might solve some issues, including the dialer issues some are reporting with the 3.4 official builds. After that his focus will be on 4.0, which is EL30 based. Consider anything from 3.4 on a beta, and only run it if you want to help find bugs. Obviously you don't mind reporting or I wouldn't be replying lol. Just follow the threads and wait untill it looks stable enough for your usage needs.
Sent from my SPH-D700 using xda premium
Thanks! I certainly wasn't busting on Random's work...and I know he has limited access to 4g for testing, so that makes it harder for him to verify these things. So
I absolutely saw what you describe going from wifi to 4g. Going from
4g to wifi, I had wifi that wouldn't turn on at all (error when trying to enable), and, like you and others have mentioned, a reboot resolved both cases. I will hang out and see if he pushes out a fix soon, and just eagerly await 4.0. If it gets too annoying, I'll restore to my
Mostly Stock... Hmmm... Is there an issue restoring an rfs backup if I am now on ext4? Heh...

Just installed the latest 3.4 revision...I think...Heh. The update was so fast its hard to tell!

And...confirming...the wifi/4g issue persists. 4g ip address is messed up on the first connect after being on wifi...reboot resolves.

So I've just flashed Matr1x on top of PAC, and everything was working great, but now my Wi-Fi doesn't turn on. It'll say "Turning on Wi-Fi, but it never does. I've tried flashing stock radio, since I have a LTE radio flashed, but that didn't change anything. I've tried rebooting and waiting for 2 minutes before turning it on, still didn't work. I've tried flashing HellsCore instead, but to no avail. Any ideas? Thanks!
This happened to me when I flashed Francos kernel. I flashed the beta r209 and it worked. There was an issue in original kernel of 4.4.2. And many custom kernel use the same WiFi settings as stock.
