My LG G4 started acting really weirdly and the WiFi would randomly turn off as well as repeatedly flash so i tried this and it began to work perfectly.
1. Go on to dialer
2. Type this code *#546368#*815# in
3. You will enter the secret menu
4. Then click on Field Test
5. Scroll down to wifi test and click on it
6. Then select OTA settings and press enable.
7. Now test wifi
I am not responsible if your phone breaks or something etc.
I really hope it works for you but I can not guarantee it. Let me know if it works for you!:good::fingers-crossed:

Hey, I've got CM10 on my GS3. When I go under Settings, the Wifi toggle is set to Off and grayed out so I can't toggle it. When I go to Wifi, it just says "Turning on Wifi" indefinitely. I also have issues with wifi tethering sometimes.
Any solutions to this? I haven't been able to find any posts on it. I'd prefer not to reset to another ROM, but if there's no other ways to fix this, oh well.
Thanks!
Flash to a TW rom and see if it works.
If it doesnt work, try the following:

So as to fix this problem,some people suggest to do a Factory reset.But, it is completely unnecessary.Instead you can try the following methods, which where tested by me successfully.
1. Dial *#*#526#*#* to reload the wifi driver.If it doesn’t work, restart your phone and dial it once gain.It will work for sure.
2.There is an app “Wifi-Fixer” from android market,which claims to be fix this problem.But seriously,it hadn’t worked for my mobile phone(Samsung Galaxy Ace).But,
if you are interested, can download and try it here.
For HTC users, I have a pretty good trick which works very well.
When you have obtaining IP address problem,
1.Turn off wifi.
2.Open “Allshare”, then you will be asked to connect to a wifi network.
3.Then select the wifi network that you need to connect from the list opened.
Magically, you will be connected without any extra effort.This works 100% sure without fail.
If that doesnt work try this:
1.Dial *#*#526#*#*.Then a message will be shown “Driver loading Successful”.
2.Now Start the WiFi, it should work.
If the message “Driver Loading Unsuccessful” is shown, follow these steps:
1. Dial *#*#526#*#* again and click options button on your phone.
2. Select Rx test.
3. Select Channel >9 .
4. Click Start and exit.
5 . After some time, turn on the wifi.It should work.

My phone won't even let me dial that, the code disappears the second I hit star the last time, not sure if it's supposed to do that. I'm gonna just try updating CM and see if that fixes it.
Hey all,
I was on CM for a while rooted and GPS worked with no issues at all.
I want to get the phone back to clean stock.
Triangled away,
Used odin to flash stock rom (UDLK3), wiped / reset everything.
everything is working except GPS does not lock, no GPS icon or anything.
GPS Test apps show no satellite fixes.
Here is what i have tried already:
Used GPS Test app to clear GPRS data and Request New - NO GO
Went to Settings
Application manager
Went to Google services framework
cleared data
Went to settings
Application manager
Went to maps
cleared data
uninstalled Map updates
Went to location services
turned off all location services
Powered cycled the phone
updated maps from android market,
Activated GPS and location services,
tested -- NO GO
Any help on how to get this fixed?
I'm in desperate need to get this phone working clean.
thank you

Woa Thank you dude! you saved my @ss,
I used the very first 'common fix"
Enter the Samsung service mode by typing this code into the dial pad *#197328640#
Then go to Mainmenu>UMTS>Common>NV REBUILD>NV REBUILD> (Important: don't exit the menu yet!)
Wait 30+ sec
Long press power button and select "Restart / Reboot"
Now check your GPS from any software that may use GPS like "Maps" or "GPS Status"...
and it worked!
thank you again both of you!
No problem I've been there before I guess it happens from switching between aosp and then back to Tw also when you flash multi carrier ROMs

Perfect! thanks
the fix i used:
GPS not locking: Unfortunately This is going to happen to some when coming from AOSP based ROMs and other carrier ports.
A couple common fixes include...

My phone finally updated to Lollipop about 2 weeks ago and ever since then, I can't get a GPS lock anymore?
Things I've already tried:

Reset & Download GPS assistance data using GPS Status app
My phone isn't rooted. I have no idea what else to do?
Here you go this is worked for me.
Open Phone, as if you were going to make a phone call and dial -
*#9090# (*#197328640# if that doesn't work)
Menu, select Key Input, enter Q
Menu, select Key Input, enter 0000
wait for the next menu. (It takes a while.)
UMTS->COMMON->NV REBUILD->NV REBUILD->SYSTEM->PROTOCOL->GPS->IMS
or, if you don't have UMTS:
UE SETTINGS & INFO->SETTING->SYSTEM->NV REBUILD->ALL
I've been working on a fix since a long time now. If you are in SD community then you prolly know me. Anyway I was able to fix this on two of my phones and it's now working fine. I tested for 12 hours now. I'll also tell you in the end what problems I'm seeing. I'm also working on a fix for that.
I noticed that a service is started when the fallback happens but if I kill that service the network also dies. But if you follow the below method it safely starts a new service which kills the one that's responsible for killing the 4G/LTE
1. Upgrade your phone to 13B firmware
2. Root 13B
3. Now download Shortcut Master lite app from play store.
4. Now add these shortcuts to your favorites in the "Shortcut Master lite app". You can search for "LTE" and click on search button
LTEBandSelection
LTETestMain
LTE System Selection
CDMAPreference
5. Now click on "LTEBandSelection" and enable all the bands
6. Save and reboot
7. You now need to enable your data and turn off your wifi. Make sure your phone is in Global mode (in settings >> Mobile networks >> System select)
8. After your phone is rebooted open "Shortcut Master lite" app.
9. Now tap on LTETestMain
10. Select Click on CDMA preference.
Now choose Band preference and select "any"
P_REV_Preference ---> "MOB_P_REV 3
This is important.. EVDO Revision --> Rev A
11. "LTE Connect w/o IMS PDN" must be checked
12. Now go back to your main menu in shortcut master lit app
13. This step is very important. Changing the timeout is important. Tap on LTE System Selection
Except "Scan duration" add a couple zeros to all the other timers. For eg: T_mpsr timer (Min) is 200
The fallback timer will reset itself after reboot. But don't worry the configuration is already updated with the new value. For some reasons the shortcut master lite app is not picking it up.
14. Now finally click on "CDMA preference" in the main menu and make sure it has the value you set in Step 10
At step 10 or 13 your network should go away and your phone should complain about "no network". That's fine. just ignore the message.
Now finally reboot your phone. That's it. You should now have 4G LTE and it won't fallback to 3G or H+
The only problem is when I'm on a call my 4G LTE is dropped to 3G/H+. But after I hang up it goes back to 4G LTE after 12 seconds. I don't know if it's an expected behavior. But I'm trying to see if there is a fix for that.
I tested this with Tmobile. Make sure your APN settings are correct.
Thanks @motorhead_biker., you rock!!!
I am on rooted 11a, flashing stock back and then will go to 13b to try this out. Was waiting for this.....
Isn't this thread a duplicate of http://forum.xda-developers.com/verizon-g4/general/guide-fix-vs986-dropping-to-3g-h-4g-lte-t3272434? Can they be consolidated?

Hi!
I've made a post in the Asus forum, with no luck and I found this page where you seem more technical :
Two days ago I downloaded the Android MM 6.0 update from the Asus Homepage downloading the version WW-4.21.40.144 , since I live in Brazil and the phone was bought here. I followed all the steps one by one till it got updated.
The problem is, since then my GPS is not working (Waze, Googlemaps ans several apps).
I tryed:
1. Giving all permissions of location to the apps
2. Puting the settings in High Accuracy
3. Restarting the phone several times.
4. Switch on and off Airplane mode and 2G 3G ands 4G (I read sometimes its interference from that)
5. Waiting almost an hour with the phone outside (sunny day) to see if it detects the satellites.
6. Every app inthe appstore that promise GPS Fixing (reseting, A-GPS and all kind of tests. Funny thing, the sensor IS working acording to those apps.
7. Factory Reset
8. Factory Reset and Erase Cache from the bootmenu. (as indicated in the Asus Forum)
9. Downgraded to Lolipop again. WW-52.20.40.196
10. Again every app to reset the GPS.
Nothing worked.
To my surprise, now I have Lolipop and no GPS. So back to basics but, worst.
The Asus forum told me to Update to the latest version, which I did:
1. Updated my phone with the latest MM version. 4.21.40.223.
2. Put the location options in "High Accuracy" and permissions needed for the apps.
3. As the old software was installed after that, I tried Waze. No GPS Signal was found.
4. Did a factory reset.
5. Put the location options in "High Accuracy" and permissions needed for the apps
6. Installed the apps GPS Toolbox and Waze again, the both can't find a GPS signal. I left the phone outside for 10 minutes.
7. Tried to install the version UL-Z00A-WW-2.20.40.198-user by bootloader, but it says it cannot update to an older version, which sounds about right. (I had to try)
What else can I do? I don't mind going back to Lolipop, but when I did GPS didn't work.
Is there any chance the new Update wrote something apart from software in the chipset that cannot be undone?
Help please, I really need the GPS!
Phone not rooted.
Thanks!

After long hours of searching, reading and trying I got it fix. How?
0. Have a full charged battery or have your phone plugged to the wall (except for the USB stuff on step number 2, obviously)
0.1. Make backups of all the info in the phone, because everything is going to be erased.
1. Download the version WW-52.20.40.196 from Asus website.(unless you need the other like CN, JK, etc, see Asus site to be sure)
2. Copy it to the internal storage of your phone in the root of it (not in any folder), via USB.
3. Get to the boot loader (Turn off phone and once is off, push the power button with the Up volume one until it vibrates 2 times. Release only the power button until the menu appears) - Search the forum for more details.
4. Select "Recovery Boot" with the volume buttons and press the power button to confirm.
The next steps are all in the Recovery Menu (once it finishes every step it goes back to the original menu, no alerts, sounds or nothing. So check every now and then)
5. Make a Wipe/factory reset, and wait, it takes some time. (use the volume buttons and press the power button to confirm)
6. Make a Wipe of the cache. (use the volume buttons and press the power button to confirm)
7. Install update from Internal storage selecting the name of file you copied on step number 2 (use the volume buttons and press the power button to confirm). It will take a while.
8. Reboot the system (use the volume buttons and press the power button to confirm)
It will restart with the phone in the Lolipop version and the GPS working fine. Even after the Lolipop updates.
Marshmallow update has a bug, that at least with my phone the GPS doesn't work. Tried reinstalling marshmallow latest version after the GPS got fix, just to prove the point, and in fact, it stopped working again.
Then I did all the steps above again and went back to normal again.
I STRONGLY RECOMMEND NOT TO UPDATE TO MARSHMALLOW WITH THE ACTUAL FIRMWARE VERSIONS AVAILABLE.
I also had this problem with Marshmallow ROM, as the GPS is not working in terms of unable to locate any signal from satellites.
However, I also solved the problem with a method sounds very silly.
I turn on my GPS overnight using an application called GPS Status.
The night I turn it on, it was locating 0 satellite (it will write 0/0 SAT). However in the morning, I found that the GPS is now working, locking on 8 out of 24 discovered satellite (it wrote 8/24 SAT).
Now my GPS is working seamlessly.
Thanks! I will try it next weekend. I need my phone this week. Hahaha
I ll post when I do so.
Do you know other similar cases of people who did that and worked?
The thing is, now I have Lollipop again an I noticed how slow the system is running with applications. I d love to have the update, but not sacrificing the GPS
I decided I won't make the test because it doesn't justify the risk and time.
I'll wait for a newer update or just stay with Lollipop.
Just to let you guys know in case someone was waiting for this
I downloaded GPS Status as suggested by SleepingAran and ran it once. Now my Waze is working seamlessly. Thanks!
There's another simple solution that works:
Follow exact steps:
1. Turn on location and set high accuracy mode
2. Open google maps
3. Move your phone several times in the shape of 8 (8-10 times should be enough)
4. Close google maps and clear it from recents screen
5. Start google maps again. Profit
