I have not had any issues with GPS not working on FR008. Did you do a full Wipe Data, Wipe Cache and Wipe Dalvik cache before you flashed?

I wiped the cache, but not a wipe disk.
Turns out the GPS *DOES* work, it just takes much longer to get a connection now. Which is odd :S

That's how it's supposed to work in a standalone mode. Enable Network Localization if you want faster lock and check with GPS Status app that your phone is acquiring AGPS data.

My phone is still really bad at GPS. It was fine on the stock 2.1 but after updating to Fr008 it sucks. Takes so long to get a connection that I don't even bother with the GPS anymore.
What can i do to fix this?

you can update radio firmware.

In one of my updates of my customized version of FR008, I ended up rendering WiFi unusable. I could tap the WiFi button in settings or on the Android power control to my hearts content but I kept getting an error. The only way to resolve it was to wipe the system, wipe the caches and then install my customized FR008.
Changing the radio I don't believe will work to solve this because I believe the problem was not with the radio itself, but with one of the data files already on the internal memory getting corrupted after flashing the ROM. That said, take great care in flashing the updated radio. Ensure your battery is fully charged before trying it, because a failed flash of the radio could permanently brick the phone.

LOOK... Fix for DJ_steve 1.7.0 3g, wifi, gps

Guys... I fixed my wifi, 3g, and Gps on 1.7.0....
1. back up your rom with nandroid (for safety)
2. go into custom recovery (streakmod or clock work) and wipe your delvik cache (i used streakmod)
3. Wipe your entire cache partition (very important)
4. Wipe all user data and perform reset using custom recovery streakmod or clockwork (not the streak's for now)
5. Let the phone boot up completely and it will force close everything really bad... let it sit for a couple minutes
6. reboot phone into DELL's 4 option recovery menu and select option 1 factory reset
7. after it factory resets using dells recovery reset it will boot up normally
8. go through phone set up as usual and use the ADW launcher NOT the other launcher
9. Configure phone to your liking and voila!!! you should be good
10. If your WIFI doesn't work at this point boot into streakmod or clockwork and wipe your dalvik cache 1 last time and your wifi will come back without a doubt.
11. As god is my witness this worked for me. If you find that it worked for you don't hesitate to hit the thanks button. I hope you have the same luck as me. Thanks
**EDIT** Been running my rom for approx 10 hours now and still no problem.... Also, WHATEVER YOU DO... DON'T USE TITANIUM BACKUP TO RESTORE YOUR APPS... Your apps will just force close... if this happens simply uninstall and reinstall and it will be fixed.

what exactly does this fix? initially when i updated from 1.6, my wifi and 3g were connected but i couldnt browse any sights, i just simply rebooted and everything was fine again

A tremendous amount of people are having issues with wifi,gps,data, and notification bars after updating to 1.7.0
This seems to be because they (including me) went from 1.6.1 to 1.7.0 and did one of 2 things... they carried over the perfmod and that is causing problems, and or the update itself is having issues updating.
Doing the steps that I have laid out has fixed 3 dell streaks and I am now running on a 99% stable version of 1.7.0 with perfmod in place which gives me quadrant scores of 2500+

I went from 1.6.1 to 1.7.0 and had wifi/3g/gps issues. I used my own combination of above to fix plus added the following to my build.propc to boost wifi/3g performance:
ro.ril.hsxpa=2
ro.ril.gprsclass=32
ro.ril.hep=1
ro.ril.enable.dtm=1
ro.ril.hsdpa.category=8
ro.ril.enable.a53=1
ro.ril.enable.3g.prefix=1
ro.ril.hsupa.category=5
My phone worked great for a few days then rebooted on its own one evening and started cycle rebooting at the Dell logo. I was able to get into the streakmod util and reflash 1.7.1 and I was up and running again. This time my build.prop was missing the same entries, but performance seems ok.

by any chance, does this fix the fact that wifi doesnt work when i switch from data to wifi and data doesnt work when i switch from wifi to data? i have to reboot everytime i switch connections now

Yes. I had that same problem and it does fix the issue

Using 2 and 3 might be enough
Hi,
for me a full wipe this is no option. I have so many things customized and I hate to enter all my crendetials and other stuff again. But I don't think this method is needed for everyone. I just did the following:
1. back up your rom with nandroid (for safety)
2. go into custom recovery (streakmod or clock work) and wipe your delvik cache (i used streakmod)
That's all. After the boot my wifi, which made frequent problems worked again like a charm.
I also disagree all those "DON'T USE TITANIUM BACKUP TO RESTORE YOUR APPS" rumours on XDA. From my experience it is actually no problem to restore the APPs. And ONLY the apps, WITHOUT data! After that you can restore selected data for the apps where you customized to much to let it go. For my last full wipe this were only about 25 apps (from 250) where I also restored the data. And it is absolutely necessary for me to restore e.g. the wifi secrets, as I have many of them and I definitely do not want to enter them every time again, because of a full wipe. And the same applies to K-9, gmail, twitter, imo, yaaic ...
KarlchenK

So you edit the build.propc file to boost wifi?
brucealeg i see you edit the entries in the build.propc file in the streak to boost the wifi radio power if you did that does that mean the wifi antenna can be boost to better reception
if dj steve is here you can look in to this this would be awsome cuz that means that we will be able to boost the wifi just like it was possible on the iphone 3/ ipod touch 2 and 3 by just installing wififofum,
But this would be different
if you where to compare wifi range once boosted on ipod to dell streak dells range sucks . and i have an ipod i dont let go cuz of it but ipod is just so small

nobody out there knows?
no answer yet now i am worried

You will most likely get no feedback on your request and this version is old now. If there were or are adjustments they will be in the later ROMs.

Need an idiot out with GPS issues

I never had to use my GPS til now and found out it cant lock on to any GPS sat. Ive had no other issuses with this phone
This is all the things ive done. I've enable TMO AWS since day one. I'm a TMO user that was a given.
My phone had the old orginal baseband, i think its MDC, then i upgraded to MDL and now i'm on the new NB1.
Ive bounced around all KK roms and even some older roms i still had saved. Nothing can get a GPS lock. I'm leaning now towards something physical, but Google now works and they can trianglulate via cell towers.
Ive 99% sure ive enable all GPS items. Location settings are on high accuracy.
Ive been using GPS status apps to help get a better location and nothing seems to be working.
Does playing around with Kernals help? I never installed one before or played with any of those. I need GPS to be working now so if i cant figure it out soon, i might just jump ship to the nexus/s5/iphone

bump up. Anyone have suggestions?
ive tried many different roms, Touchwiz and not touch. All diffrent basebands. I dont know what kernal work with what roms so ive been avoiding that

A kernel is not going to help. Have you gone back to stock rom and still have the issue? It sounds more like it's a hardware issue. Like the gps antenna is not working.

sadly i'm thinking the same thing. It looks like a cheap part but no idea on taking it apart just yet.
I always thought a kernal acted like a driver for computers,

The kernel is the boot image and in essence it interprets between the software and hardware. If you've flashed other roms you've flashed a kernel each time.

ah, understood. I thought it was like the baseband where i had to manual change it.
Does anyone know where the GPS antenna is located at? Is it a part i can swap out or attached the main board. I just pulled apart the phone looking for obvious parts not being connected and everything looked good.
Ebay listings GPS antenna as the 3g blue cable that runs down the side of the battery. I dont think thats the GPS antenna but it does cost a small amount but i dont think that will help.

before you tear it apart try what jd suggested and odin back to stock. you may want to backup and format your internal and ext sdcards also. they can harbor old junk that may effect new roms.
also, are you wiping all including system before flashing and on your phone and some roms i believe you have to odin a modem.bin file as part of flashing. am not familiar with that stuff as i am i337 and never used odin. "yet"
not sure if any of it will help--but--
good luck

Might need more info on what our suggesting.
I'm wiping data and the option under data in clockworksmod.
I don't have anything important, everything is cloud.

I think he is suggesting that first you get the STOCK MDL Odin package and flash it. Then wipe all data, dalvich cache, and internal sdcard (remove your external sdcard before hand). Then power it up and IMMEDIATELY turn OFF WiFi, you do NOT want it to try to update on its own. Now check GPS and see if it works.
If it does work now (the FIRST LOCK can take a bit of time) Then again use casual+motochopper to root and install twrp. Then flash a good ROM. Once that is done you can check GPS again and make sure it works, it may take a bit since it will be the first lock again (I always had trouble with MK2 modem for some reason. All the rest worked perfectly).
Or just make sure you have the ROM you want to run on a external sdcard. Then remove it for safe keeping. Now go into twrp/clockworkmod and wipe data factory reset/ cache/ dalvich cache/ and sdcard. Power off the phone after it is done and reinsert your external sdcard. Do not boot up but go directly to where you have the ROM at on your external sdcard CIA twrp/clockworkmod and flash the ROM. This will give you a perfectly clean slate. Now once it is done and booted up let it sit without touching it for at least 5 minutes. Then check GPS. If it works you are good to go. Then download any of your apps from the play store (not from titanium backup in case some system setting are being reinstalled with something). Once you have your apps back check GPS again to make sure one of them hasn't caused an issue with your GPS. If all is still good use titanium backup to recover your DATA ONLY for the installed apps.

I have no idea why
I had the same problem, and I just fixed it too.. I don't know if this will cause the problem but here it goes.
I found this solution from the forum, but forgot where..
1) I installed the rom (AOSP) I wanted and checked if gps worked (but didnt work, checked with GPS Status)
2) Went to recovery, nandroid the Rom
3) Clean install to Rom that GPS worked (TW Rom) and again checked if gps worked (and worked, also checked with GPS Status)
4) While leaving the GPS toggle on, went into recovery, and without wiping anything, restored the AOSP rom
5) booted checked GPS Status and I was able to see the satellites..
I have no idea right now if this will cause any trouble.. but at least gps works in aosp..
I'll update again if I face any problems
Good luck

Its working now. Not 100% sure what the problem was but that's for everyone with the suggestions.
I flashed about 15-20 different Roms from touchwiz to aosp and miui thing.
Opened the phone up and looked for basic things not connected.
Removed my case and wireless charger insert.
Did the MDB Odin flash. With stock ROM. It didn't still didn't work.
Finally gave up and flashed back old GE ROM. And all of a sudden it works.
I think the Odin wipe and SD card wipe had a big role but not sure. Either way it works now. Might not be the fastest connection to GPS as it takes a few moments now but it works. I'm normally locked on to 13/21 SATs out there in a matter of 2-3 mins.
Now that it works I'm a little weary of trying MDL

Unable to find satellites or lock on with V980 with custom ROM

OK guys I've completely given up.... I've completely bricked one phone and keep soft bricking another and have a third laying around, and I just can't figure it out.
I have a G2. The GPS works in stock 4.2.2 (Tested in GPS status and toolbox app) then I root and flash a new 4.4.2 ROM (tried Malladus and Mahdi) and bam the GPS doesn't work anymore.
When I revert back to stock (through lg flash tool) it works again. HOWEVER, if I just flash the stock 4.4.2 LG ROM GPS works once agai.
Do you guys have any clue wtf is up? I can't figure it out... I've tried changing the GPS config, the drivers, every tool in GPS toolbox. Tried GPS test and I just get nothing. Is there something completely obvious that I'm missing here?
I've also tried the trick where I backup my custom ROM, revert to stock and get GPS lock then restore my custom ROM. doesn't work.
thanks!

Try getting a GPS lock on stock using GPS test. Then go into maps and verify the lock is OK. Let it sit in maps for a couple minutes. Don't press the back key, just use the home key and reboot into recovery and flash your ROM.
If that doesn't work, get a lock in stock using the same method and when flashing your ROM don't wipe /system. I know it sounds weird but I had that happen a few times with me and not wiping system allowed me to get a lock on the custom ROM.
Let me know how it goes.

Ok I was able to fix it!
But in a completely random way.
I'll try to describe it in as much detail as I can so anyone who follows will not spend as much time as I did.
First: The problem. (This only happened in custom ROM)
In stock, my GPS worked fine, no problems and I got good lock and everything.
In custom ROM's, however:
My problem wasn't just that I couldn't lock on to satellites, I wasn't able to even see any satellites.
In GPS Test I wasn't seeing any satellites. In GPS Status and Toolbox in the middle right where it says fix/sat my phone was displaying -/-
I tried everything there was, from downloading GPS states to changing my gps.conf file to basically everything I could find online, and nothing worked.
Yet everytime I went back to a stock ROM, it worked perfectly 0.o.
Fix:
Today I gave it one last shot.
I'll try to describe everything I did down to the letter in case any of it makes a difference
I ran LG flash tool, let the phone turn on, but DID NOT activate.
Then I ran LG flash tool again, and let it activate and do it's thing.
From this point on I ran GPS status and toolbox, and I was both seeing satellites and locking on.
Then I turned on Maps (as suggested) and let it lock in on my position and sit there for a few minutes.
I ran ioroot and rooted.
Then installed TWRP.
I then intended to flash to TWRP 2.7.1.0 but somehow flashed 2.7.0.0, and didn't bother changing it. (I don't recommend doing this as it could cause problems.... I was just too frustrated to change)
I backed-up EVERYTHING.
Then I downloaded and saved onto my phone Malladus, Gapps, and the 11a-24-twrp.zip file that was needed.
I flashed it, and BAM it worked.
I turned it on, activated and immediately ran GPS status and toolbox and it worked right away.
Before if I flashed I would just get -/- in GPS status and toolbox, but now I find satellites and lock quickly.
Good luck to anyone who has this problem!
Try following my steps, they may just work.
And thank you for the help!

[Q] [solved] GPS Not Working After Cyanogen Mod Install

Hi All,
I just got a new used Samsung Galaxy S4 on Sprint and brought it over to Ting (way, way, way cheaper). I got everything working with the stock ROM, including GPS, but I wanted to install Cyanogenmod, so I rooted it, flashed TWRP 7.8, and flashed the latest Cyanogenmod (snapshot M12), with Gapps, and a zip file with the Ting data XML files to get 3G and LTE working.
Everything seemed to work great, but then while driving I noticed that the GPS just did not get a lock. After trying for an hour, it still had nothing. I installed GPS Status and saw that it had no satellites. Clearing the GPS cache and re-downloading data with that app did not solve the problem. I tried GPS Doctor without success and the GPS fix equally without success.
I rebooted, then factory reset, then erased everything and flashed the latest CM nightly, all with no success.
I found some similar problems online at these places:
http://myblog-online.co.uk/2013/12/the-continuing-saga-of-my-galaxy-s4-custom-roms/
http://forum.cyanogenmod.org/topic/98811-gps-not-working-23rd-nightly/
http://forum.xda-developers.com/showthread.php?t=2172670
These are all old and none gave me anything that useful. Is it a GPS radio issue? Is there anything I can do?
I also just found this page: http://wiki.cyanogenmod.org/w/Known_Issues_page_for_d2lte, but it is for the S3, not sure what to make of it.
I made a nandroid backup of my stock rom, but then I copied it to my computer, and when I copied it back again it didn't work. TWRP failed to restore with the error "No partition selected for restore".
My plan now is to flash the stock rom with odin, confirm that GPS works there, and then try again, but this is becoming a huge time sink and I have a lot of other things to do.
Does anyone have any ideas how I can fix this? I am pretty sure it isn't a hardware issue.

That's is pretty much what you have to do. Its go back to stock and get a lock there in maps. When you have a lock just go back to recovery and flash your custom ROM of choice. That is pretty much the only fix.

Thanks ROMANTiC KiD,
Good to know that I am heading down the right path before I spend a lot of time on this.
Should I not erase everything when I flash the custom ROM? I am pretty sure last time I used TWRP advanced erase to clear everything on the phone before installing. Should I just do a regular factory reset in TWRP to install CM in order to keep GPS functionality?
Thanks!

Yes sir you can factory reset in twrp just remember to back up your files first! And you should still retain GPS lock.

Thanks for the confirmation. I did exactly that and I can confirm that it did indeed work.
Thanks so much for the help.

Hi all,
Sorry to resurrect an old thread, but I am having this issue and the stock firmware flash isn't solving the issue. It is all very odd because it doesn't actually retain any kind of lock after flashing. I'm following instruction on here, but after locking gps on stock, then going to CM I cannot get a fix. It either had a massive radius on Maps, or it just locks to my home or work location.
Since trying much more I have managed to get the occasional satellite lock via GPS Locker, but even then as soon as I move from either my house or work, it can't find anything to lock onto and just defaults to a static location.
Is there anything you would recommend? I have 2 Samsung GS4's and they both exhibit the same problem. I have also tried this on an S4 Mini, but that retained lock just fine. I'm really confused as to what to actually try. If you could recommend anything I'd be very grateful.
Again, I'm sorry to res an old thread, but no one has been replying to the one I started for this issue :/

Your problem may be that there is some new issue with the newer firmware. I had success by first flashing the *old* firmware (you can download it from my dropbox here: https://www.dropbox.com/s/o3f3ynyezyy4yw9/L720VPUFNAE_L720SPTFNAE_L720VPUFNAE_HOME.tar.md5?dl=0) and then upgrading to the second to last firmware update for the GS4: which gives you Android 5 but without fixing the MMS bug.
After that I flash TWRP with Odin, and then do a full erase in TWRP followed by flashing the latest CM. That series of steps works for me every time, although I found that large changes to my physical location (e.g. flying to England from California) cause it to break again. I actually had to sit in a cafe in an English airport with my laptop out flashing my phone back to stock just so that I could use Google maps to get to my mother's house. It was pretty ridiculous. Because of that and other issues, I now just use stock. I hate it, but I do it anyway. Good luck.
