yet another wifi problem - Galaxy S 4 Q&A, Help & Troubleshooting

Hi, my phone came as a re-furb and it had a united arab emirates rom on it(ramadan dates on calendar, all languages set to arabic etc.), wifi was working on this rom fine.
i upgraded to xxungng8 and wifi also worked. the next day when i took my phone off charge it dropped wifi. the only way i was able to get it back was installing the adam kernel. i had tried updating the modem(non hlos wifi fix). that was last friday, the wifi stopped working the nxt time i had finished charging my phone, now i cant get wifi working atall, it did work once after the battery had ran right down and i recharged it, but only for a few minutes. i changed the rom to xxufnc9 because on the thread it showed it fixed it for a lot of people but not me unfortunately.
when i try to turn on wifi the slider goes across to the 1 but is grayed out, it then jumps back to 0, and does the same each time i try to start wifi. ive got a build.prop file(through adam kernel) which changed the setting from true to fasle also.
i have tried updating the modem to the latest(GNk4) but it wont take on the phone, when i dial *#1234# i get
AP:i9505xxufnc9
cp:i9505xxufnc9
csc:i9505oxafnb8
i think if i can get the phone to take the wifi fix modem this should solve it?
i have tried flashing with oden, getting pass, manually rebooting(both power for 10 secs and battery pull), then flashing again straight into recovery then reset but no luck so far.
Any help would be great, thanks.
so obciously when i tried the update the modm it didnt take.

Install this APP and add some screenshots here pls.

1. Download, unzip and flash the latest firmware for your device via ODIN: HERE.
2. Make a data backup and a "factory reset" (Settings > Accounts > Back Up and Reset > Factory Data Reset > Reset Device > Delete All/Erase Everything) then.
3. Try if you have wifi when your device reboots.
4. Dial *#1234# and tell me what appears :highfive:

You don't need it coz your KNOX:0x1. You can root your device with other methods like HERE.

Seems to be a hardware issue. Remember dont mixmatch bootloaders and everything they are the ones that mess up with WiFi very easily. Reset your phone once more go into download mode and flash the latest firmware for your phone 2 times. If that doesn't work then you have a hardware issue.

Just curious if you have flashed the ROM @Joku1981 gave you the link for a second time? That should also correct the bootloader issue you're having. It should be the same as the baseband.

[Q] What did I do to my I9500 (probs with 4.3, ODIN, recovery, etc.)?

This is where my I9500 is right now:
AP: I9500UBUBMG9
CP: I9500UBUEMK1
CSC: I9500UUBBMG9
I know that MK1 is from 4.3 and MG9 from 4.2.2. So I'll tell you how my phone got there:
Last week I flashed stock 4.3 (and did a backup in CWM recovery before flashing.) To my dismay, everything with 4.3 was very laggy and unresponsive; services were stopping left-and-right. A battery-pull/hard-restart had no effect. The lag was so bad that it took me 2 to 3 minutes to properly shut it down each time.
So at that point, I planned to reflash 4.2 (I was not aware of the problems of downgrading after upgrading to 4.3.) In trying to do so, ODIN (on my PC) would just freeze partway through, never completing the process and giving me some error message. In trying to reenter ODIN mode, I'd get the yellow triangle screen each time.
After some searching of the forums here, I found and did something (I can't remember exactly what it was) but I managed to enter ODIN mode. This time I tried reflashing again. Same thing, of course. But this second time around I noticed the "warranty bit: 1" thing that I hadn't noticed before (I figured it had to be something to do with knox that I had read about in upgrading to 4.3.) Here's my current screen in ODIN mode:
PRODUCT NAME: GT-I9500
CURRENT BINARY: Custom
SYSTEM STATUS: Custom
WARRANTY BIT: 1
Anyway, rather than keep messing around with ODIN, I thought I would just restore the backup I made. But instead of entering recovery, I kept getting the yellow triangle. Finally, as a last-ditch effort, I ended up reflashing CWM Recovery through ODIN. Then I was able to successfully enter recovery mode, restore my backup image. Now my phone runs just as it did before (just with a different baseband version.)
What does all this mean for my device?
Any ideas why 4.3 was crashing everything? Is there something different I should do before I reflashing 4.3? Or should I wait for a more stable 4.3.x? (I assum the errors I experienced in ODIN were due to trying to downgrade to 4.2. I would certainly hope to use ODIN in the future to flash new versions.)
1. You cant come back from 4.3 to 4.2.2
2. You void ur warranty for the step 1
3. ODIN didnt finish any process for the step 1 too.
4. You could come back to 4.2.2 coz u restored one backup. You still having new bootloader (warranty bit:1) with old 4.2.2 firmware.
5. Go to Apps - Settings - More - About device and make us a screenshot pls
4. Conect ur phone to Kies (android 4.2.2) or Kies 3 (android 4.3) and tell us what appears close CSC btw (). We need know ur zone code and download the correct firmware for ur region

TPA is Panama, right? When I flashed 4.3, it was indeed "TPA" (so I'm really clueless why it was so laggy and unusable.)

OMFG! I completely mis-remembered what I actually did (I can't even believe it!) Thank you for jogging my memory.
Initially I wasn't too keen on the 8-hour ETA for downloading 4.3, so I reflashed stock 4.2 in ODIN. And it was through Kies that I installed 4.3. Obviously in its stock 4.2 state, Kies recognized it as "updatable" and initiated the download/update of 4.3. So the whole unstable installation I had is even more perplexing. Oh well. I'm downloading 4.3 now and will try updating through ODIN. I'll report back. Thanks.
Up and running 4.3 without any issues. Thanks.
can i downgrade from 4.3 to 4.2.2 without any issue, includingwith 4.3 bootloader, using the latest 4.3 modem, the devices it's running great, no problem so far, and yes TPA is for Panama also PBS, CPA, CPW

[GUIDE] Fix WiFi not working properly after unlock

Hello XDA Team, I've had a problem with my Canadia Galaxy S4, i requested an unlock to a guy which unlocks phones with some Octopus or Z3X box, for some odd reason the program would not read the phone's codes to unlock so the unlock process failed, before leaving this guy clicked on some "repair NVM" button in the program, when in home i noticed the phone's wifi wont turn on properly, half-greened button & when it managed to turn on it would not save the passwords once i connect to some network, it's a very similar problem as this: http://forum.xda-developers.com/showthread.php?t=2661859 , i've flashed Stock Telus Firmware & other canadian carriers with no luck, except by CyanogenMod11 where it works perfectly, done full wipes for clean installs, i also tried to move the CM11 etc/wifi/ files to the Stock firmware which makes it to turn on a little faster, but still no luck saving the passwords, the phone was in 4.3 version then updated to 4.4.2, didn't worked neither.
I have searched all over google for a solution but couldn't find any
Is there any solution to this? or this guy really damaged the NVM thing he clicked? he had my phone for almost a month with no success repairing, any suggestions ? Any help would be greatly appreciated.
***********EDIT****FIXED****************
Hello everyone again, i managed to fix this problem by setting all permissions to all EFS folder files, This may fix your WiFi problems after an Box unlock procedure.
Hello, i took a couple of screenshots to be the most specific & easiest for you all.
First of all you need to be rooted.
1.- Install Root Explorer & open it up, it will show you this once you open it.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2.- Look for the EFS folder & go throught it, after that select all the files and folders inside.
3.- Press menu softkey & select the Permissions option.
4.- Select all of the permissions as shown in the image & click Ok.
After you done that, reinstall your Stock Firmware or simply reboot, & check if it's working properly again, I hope this helps.
How do you set all permissions to all EFS folder files?

Yes, you do need to have Root browser, but i'd recommend you to use Root Explorer because you cannot set permissions to all files at once with root browser.
Thanks!!! It works, followed your steps and rebooted, auto connected to WiFi. Thanks a bunch. I recommend this tutorial if anyone is have WiFi issues with their GS4.

Hiii....I am also having the same problem.My phone was unlocked by a guy and everything was working fine then.From next day the i could not turn on WiFi(It would go grayish for some time and then return to normal).I tried searching for it online and found the following soln
1)Reboot and check(Didn't work)
2)Factory Reset:After doing this it worked for that initial scanning but again was back to normal once wifi was switched off
3)Factory reset and installed root browser(my phone is rooted as i was able to install root explorer) and tried renaming the wpa-supplant config file
.This was worked for me for like 4 days.
After that again the problem is back and its even worse.It is immediately turning off as opposed to delay in previous case.When i tried to follow the same procedure the config files are not present.I could not on wifi even after factory reset even once
As i am a new around here detailed help would be appreciated;
My Device Features:
1)Andriod:4.4.2,SGH I337
2)Baseband:I337UCUFNC1
3)kernel Version:3.4.0-1125940

Okay then follow this guide: http://forum.xda-developers.com/showthread.php?t=2663545 an user with this problem fixed his WiFi with that guide, i believe you're using AT&T Galaxy S4. king regards.
Thanks it works
Thanks for the great idea for modifying the permission.
It works on my SGH I337 NI1 Unlocked & of course Rooted.
I uses ES Explorer with Root Explorer enabled.
Using this explorer, I have to modify the file one by one, but it is fine.
One problem that is still unsolved for my S4 is: it keeps forgetting the wifi networks after it is restarted.
Perhaps any other file(s)'s permissions need to be modified?
Thank you so much. This problem has been driving me nuts. I just fixed the permissions and WiFi is now working the way it is supposed to.
Yaaaayyy THANXXX it worksss
Thanks!
Wow, it worked. Now I wonder why... Surely it's not a great idea to give global permissions to every file in this folder, and also surely there is just one or two files that need changing.. perhaps just the wifi folder?
Anyway, thanks a lot! And if anyone knows why this works, I'd love o know.
Oh, I'm on an AT&T S4.

I believe it corrupted the efs folder while in the unlocking process.

So I have AT&T SGH-I337 with NJ4 build and baseband. I recently rooted and installed Safestrap recovery and everything was fine, but then messed up when flashing a rom and softbricked my device. When i restored it by flashing an NB1 stock build, wifi was fine, and then i went and installed safestrap again and restored from nandroid. I then noticed that my wifi wasn't on. From then on, the wifi will NOT turn on, no matter what I try. I tried factory resetting, flashing the right modems, etc etc, and i just can't fix it. Any help?

Can't turn on Wifi on GT-l9505

Hello,
I was cleaning my closet today and found my long forgotten Galaxy S4. I turned it on and a update notification poped (for 4.4.2), so far so good. The updated installed successfully and everything is wroking fine, however I can't turn Wifi on anymore. It worked just fine before the update!
So far I've tried doing the following:
I'v taken the battery out, both after shutting down the device and while the device is on.
I've factory reseted the device.
I've re-flashed the same official build using odin.
I've rooted the device to check wpa_supplicant.conf permissions and they seem to be fine (system:wifi)
I've flashed Wifi-fix kernel.
None of the above helped. I still can't turn it on. When I click the toggle or swipe the switch in settings it hangs a bit, stays dark then automatically goes back off on it's own.
Any help would be appreciated!

Thanks for the reply. That's the exat same tutorial I used to root my device (so I can check permissions of the wifi config files). I flashed a the official build image after that so the kernel shouldn't be the problem?
Btw I downloaded the image from sammobile and the md5 was correct!

I was cleaning my closet today and found my long forgotten Galaxy S4. I turned it on and a update notification poped (for 4.4.2), so far so good. The updated installed successfully and everything is wroking fine, however I can't turn Wifi on anymore. It worked just fine before the update!
So far I've tried doing the following:
I'v taken the battery out, both after shutting down the device and while the device is on.
I've factory reseted the device.
I've re-flashed the same official build using odin.
I've rooted the device to check wpa_supplicant.conf permissions and they seem to be fine (system:wifi)
I've flashed Wifi-fix kernel.
None of the above helped. I still can't turn it on. When I click the toggle or swipe the switch in settings it hangs a bit, stays dark then automatically goes back off on it's own.
Any help would be appreciated!

Did they write the cause in the repair quote?
Two ways of sorting this one.
1/ Flash a stock firmware which will fix your GSM and LTE modems along with the baseband. You'll wipe your internal storage but that's the way to go if you want a clean start.
2/ Flash the right GSM and LTE modems along with the baseband. Good if you want to keep your existing rom and not wipe you internal storage however -
It is essential to run the same versions for the Modem and Non-Hlos files as the chips talk to each other while the phone operates.
MODEM.bin = firmware for GSM Interface
NON-HLOS.bin / Firmware for LTE & WiFi Interfaces
here's where I got my modem and LTE modems from:

Read OP, please.
If my solution doesn't work I can only think of hardware issues. Btw - a thanks for responding is always welcome.

[Q] No wifi, sound and very slow phone after reverting to stock

After using official CM12 for more thatn one year, I decided to go back to stock to sell phone. I moved out of stock before knox, so I didn't have it on my phone.
First I did exactly as described in this post using Odin: http://forum.xda-developers.com/showthread.php?t=2265477
They indicate 2 ROMs for Brazil, and I chose 4.4.2 - ZTO-I9505VJUFNB2-20140305104104.zip
Everything seemed OK, but there was no wifi. The button to turn it on simply didn't move to ON position. That's when I messed things up.
This is the list of actions I did after that:
1 - Hard reset. No success.
2 - Re-flashed same ROM using re-format and PIT file. No success.
3 - Flashed different modem (VJUFNC1) as described here: http://forum.xda-developers.com/showthread.php?t=2192025. Original modem before that was VJUBMG3 (I'm not 100% sure). Things got worse. I still had no wifi, but I also lost sound (even on boot screen there is no sound. Phone also got very slow stuttering. I'd say it's not usable.
4 - Tried flashing a different ROM form Sammobile specific for my country/carrier: I9505VJUFNC1_I9505ZVVFNC1_ZVV. Stil slow, no wifi, no sound.
I've reflashed these same two ROMs with and without pit a few time now. Tried hard resetting and reverting to original modem. No succes. I'm lost, to be honest. Any ideas how to fix this?
I've attached some screenshots from Phone INFO Saumsung details app:

Problems that i see:
- Bootloader and baseband didn't update for that you still having problems.
SOLUTION:
1. The correct firmware for you is this ONE. Download, unzip it and flash the .tar.md5 via ODIN like on the example (pic attached).
2. Let it boot normally till the final. Shutdown your phone and boot in DOWNLOAD MODE again.
3. Flash the same firmware like in the step 1 via ODIN.
4. Dial *#1234# when the process finish and tell me what appears.

Hey, you rock! I flashed it only once and everything is working again. Sound, wifi, everything! Should I still flash second time? Since it's all fine I'm afraid of messing again.
Dialing *#1234# gives me:
AP: I9505VJUFNB2
CP: I9505VJUFNB2
CSC: I9505ZTOFNB3

GPS has gone whack

Hey guys,
Have been running a 4.4 ROM for a while (900i) and I finally bit the bullet and installed Phoenix Rom (900F).
It worked fantastically (aside from the NFC). I did notice the GPS failed to hookup. This was a problem so I restored my kitkat backup. However....
The GPS now no longer works!!? I download an original Kitkat Rom for my provider (optus) off Sammobile. Flashed with it with Odin and still it fails to connect.
Googling has led me to no immediate resolutions. I flashed 4.4 stock again with Odin and did a 5.0 Lollipop update OTA in hope that it would fix things.
It hasn't worked thus far. Was hopefing someone would know what was going on or could provide me with some guidance.
Cheers.
Tried a full factory reset from recovery / android settings after flashing the stock ROM ?

Yep. Still no dice.
Only other thing I can think of is to grab the correct PIT file for your model S5, flash that and a stock ROM at the same time using ODIN
If it still doesn't work after that, it sounds like a hardware issue
You say your phone is the G900I? And you flashed a G900F ROM to it?
Other than that, make sure other devices can get a GPS lock, make sure it's not just the weather stopping it working

Not exactly sure where to get the correct PIT file to flash.
I'll try disabling all weather settings though, didn't think of that one. Cheers

Scroll down and choose your model S5 PIT, Extract to .pit, add to PIT section, and flash with the stock ROM in AP or PDA section as normal
And I meant the weather outside stopping the phone seeing the satellites, heavily cloudy days can cause problems sometimes, but check settings, connections, location, is set to high accuracy

Damn... 'Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again' :crying:
This is what I ran:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
EDIT: Running it again. Appears to be running. I think my USB hub died which is why it 'failed'. Installing applications now and will post back as to whether the GPS is working or not.
I actually have a place to be which is why I'm desperately trying to fix things.
Unfortunately it hasn't fixed the GPS. I'll have to print out the Google Maps instructions.
EDIT 2: Tried this:
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
Click to expand...
Click to collapse
No cigar. Will to another factory reset when I have a chance.
EDIT 3: Did another factory reset through the menu and it said location set my GPS. I nearly fell over!
We're working. Thanks for all your help *Detection*
Great!
Hi there , i've had the same problem when installing a custom rom like PopWiz Telstra or other rom don't no why but this fix works for me every time :
Install latest rooted TW (original Samsung Touch wiz rom) like (Alexandr ROM )
Install from play store Shortcut Master or Phone Info
Open ‘Secret Code Explorer’ menu, scroll down to 27663368378 and launch it (select ‘Launch 0’, root is required).
Then select the latest menu option Hardware sensors
Then the latest option restore (rebuild) NVRAM (or something like that. I’m writing this from my memory )
Reboot the phone
Try GPS – it should work
I have just copy paste it from a site in works like a charm on g900f
Alright. I'm unhappy with the Optus Lollipop 5.0 stock. I can't install xposed because its odexed so I'm going back to the Phoenix 900F!
This time I'm going to install it with TWRP.
Will then go through the troubleshooting attempts in an attempt to have a GREAT rom with a fully functional GPS!~
