Maybe a wrong modem version, or damaged wifi config files.
Workaround for Wifi (need root):
With a File Explorer.
Navigate to /data/misc/wifi
Rename wpa_supplicant.conf to wpa_supplicant.conf.old
Delete wpa_supplicant.bak.conf
Reboot device.
If you need restore the saved networks, check this after reboot.
You will have three wpa_supplicant's.
Enable and disable your wifi for recreate files.
Open the wpa_supplicant.conf.old file, and copy the lines between network and the end of file.
Example:
Code:
network={
ssid="MY_WIFI"
psk=aaaaaaaaaaaaaaaaaaaaaa
key_mgmt=WPA-PSK
priority=662
autojoin=1
usable_internet=0
skip_internet_check=0
}
And past in end of new wpa_supplicant.conf.
The same thing happened to my wifes gt-i9500 a few months ago. Her phone had to have the wifi and blue tooth hardware parts replaced.

Then It Works ? After Replace Wifi And Bluetooth ? Works
Yes, I originally took it to a Samsung service centre who wanted to replace the motherboard for an expensive price. I then took it to a normal phone repair shop who replaced the wifi and bluetooth hardware components for a fraction of the price. They did not use original samsung parts but her phone is now working fine for both wifi and bluetooth.
Please Help Me

Hey man I had the same problema I got a Galaxy s4 i9500 on friday from a friend it was almost new, but wifi wasn't working and bluetooth he didn't notice, I flashed russian lollipop, indian and honk Kong, some módems nothing worked even downgraded to kitkat and rooted to edit the wifi file mentioned before in this thread and build.prop too,
I fixed it, it was kindda silly for me the bluetooth and wifi antenna were kindda loosy, I took apart the pone a Little, on the back I removed all the screws, and with a tool opened it, the back part the one with the screws has the antenna and the bluetooth they are encased in that plastic part if you're looking the phone from the back it would be left top part almost, and you can try squeezing the phone a lil bit in that part, after putting it back togheter I just squeezed it a lil bit and the problem was fixed so it might be a hardware issue in this case it was kindda loosy
If this is your first time flashing lollipop..just flash it twice and ur problem is gone..dont forget to wipe after first flash..
wifi issues
Hi everyone!
When i flash the rom detects the wifi but the next day was no longer detected. Turn off and turn on the wifi and nothing it stays searching and shows no network. I tried with the official rom, cyanogenmod, GE but no luck.
I tried that said in post # 2, but nothing.
Any ideas? i'm using S4 GT-i9505

I am in Singapore on Singtel network.
I flashed about 10 days ago the I9505XXUBMEA rom from Sammobile.
Since I flashed I have had very very poor signal (voice : calls not going through or calls dropped and data : close to no data at all) .
I have a limited experience with flashing roms.
I have checked that it wasn't something related to my network or card by switching the sim back to my GS3. No issue there...
I tried to flash DX... modems with no change...
Can someone help me ?

I would suggest Reset the device completly which is suggestable after an update
And see mostly some bad system file would be causing this Reset from device will clear finger crossed
Note: Data will be lost incase u do reset back important things first
Ok, few more solutions for you.
1) Try a CSC change, not sure if that has any effect on your network. Find one that's for Singapore or SEA region.
2) Try flashing a rom from Dejembey's, haven't had any network issues there. http://forum.xda-developers.com/showthread.php?t=2250824
I'm on MF8. Maybe you should give that a try.
Ohh and please share your wiping procedure you tried earlier.
Cheers.
I flashed the new rom without problems.
I am still mainly stuck on G for the data...
It might not be the rom or modem...
Any ideas of what could be the cause?

Hi I have international version of S5 G900F. I flashed the phone with UK BTU stock rom. Now the problem is I cannot connect to the Network.
I tried going to Settings->More Networks -> Network Operators -> Select automatically . It took 5-10 mins to search but cannot connect.
Sim is not locked as it was working before I flashed the stock rom. also I read somewhere in internet that once the phone is region unlocked, it is permanently unlocked to use any other country sim. I don't know the original region of my phone but I bought it in Uk from 3rd party dealer not from any carrier.
I can think of two thing at the moment. It should be either regional locked again, but it does not prompt any thing to activate or enter pin or anything like that. or it should be wrong modem.
Is there a way to find if the phone is region locked ?
and is there a way to find correct region of the phone ?
the label on the box was removed so I cannot find from the box as well.
Thanks in advance.
I still haven't fixed this problem. Could someone suggest how to fix?
I've attached some screenshots with my phone info.
first image shows NETWORK:UNBLOCKED and IMEI Certi: PASS
-> I think this means, the phone is not blocked by network, and IMEI certificate has passed so it's not stolen or lost claimed phone.
another screenshot is the Firmware and CSC code/country information,
-> this means, this phone is build to sell in UK, so UK sim should unlock the regional lock.
Also the phone was working fine before I installed stock rom which I dowloaded from sammobile.
in the sceenshot, one of the network is connected but it says emergency call only because it cannot register to the network.
It is not sim lock also, because when I put T-mobile sim it does not ask for pin to unlock also.
what is wrong here. any idea guys? xda supposed to be the biggest android forum and samsung s5 is one of the most popular phone at the moment, isn't there anyone who have similar problem and solved? or atleast give some reason this cannot be fixed at all.
does the TMobile sim work? does it register with the network? If yes, then call the provider (of the other sim) and ask what's going on. Maybe you have a broken sim?

I've tried with Orange sim, and it still cannot register to the network. When I put the orange sim, it pop up a dialogbox asking to choose a network provider, there was two options, T-mobile and orange. So it is detecting the sim, but it cannot register.
And also, I tried my sim in another phone, and my sim works in another phone without any problem.
Did you try to flash the firmware again, and then after that restore factory defaults?

Yes I did, still it didn't work. I emailed samsung customer service with the problem, and they asked me to restore factory defaults.
I did that again but didn't work.
I tried one custom ROM as well. same problem in that rom.
You're rooted? If yes then there might be problem with the modem part of the ROM, can you install the official one part ROM and try with that?

I've installed stock rom several times, and several different versions( from here: http://www.sammobile.com/firmwares/1/?model=SM-G900F&pcode=0 ). Rooted several times, installed modem.bin files several times from many custom rom/ stock rom. None of them worked. I tried installing modem.bin when not rooted as well. And all the attempt failed.
I did everything I could possibly think of , Then I posted the question in the forum.
You have the IMEI ??!? Or it is lost?? Then only per efs-backup…
Or sim is broken…

Sry XanoZuke, I could not do anything to fix this, so I returned the phone and got another handset. I now have Exynos Octa-core version. Found snapdragon version is more power efficient. My phone gets heated very quickly.

Don't worry, I found out that the motherboard was water damaged (the irony of life....), so a bought an LG G3.
Regarding the Exynos chip, I'm never buying anything exynos ever again. The performance is not as solid as Snapdragon and it gets heated really fast. Still, thanks for your reply! ?

Sorry i end up selling the phone as is..
Same deal
My g900f has no mobile services sims fine
I have the same problem.
Cannot connect to network after flashing new ROM. Since then I tried about 10 different original roms and couple custom roms. Number of different MODEMs and BOOTLOADERs but with no joy. SIM card works fine in different phone.
Also I tried to load different CERT files and QCN with Z3X Box but that didn't help either.
I've tried *#0011# command here are results:
with LTE/WCDMA/GSM auto-connect:
imgur.com/i69HCBM
with WCDMA only:
imgur.com/QPbvKHG
and GSM only:
imgur.com/8InhQWQ
It seems that GSM is not working at all.
At this stage I run out of ideas and probably gonna get rid of the phone as it is or use it as pimped-out ipod touch
(sorry for messed up links but I can't post to outside sites yet)
Hi guys !
I've just bought a samsung galaxy s4 (i9505) (a used one not new) and i flashed Imperium v7 and modem GNF1 and bootloader GNF1 (initially the phone was on stock 4.2.2 and the problem was already there).
My problem is that i don't get the network i rarely see two or three bars but it directly goes to zero (i can see the no network sign) and stays like that until a reboot (as said it drops to no network very fast).
So my question, is it software ? (should i flash the latest samsung stock firmware ?) or is it hardware ? (replace the internal network ship ?)
Or is it a common problem on S4 i9505 and no solution cannot be found ? :crying:
Could it be related to CSC ?
Anyway, i hope anybody can help me because i really like this phone and the rom that i just installed ..
Feel free to ask me about additional informations.
EDIT : I already tried :
1) the modem+bl FNDA => same result
2) force the phone to gsm only => same result (maybe better but even it solves the problem there is no point to not having 3g activated all the time)

It's going to be pretty difficult to narrow this down with what you've posted. You say the problem was "already there" when you got the phone -- how long did you use it on the stock 4.2.2 rom before flashing a new one? Did you see exactly the same behavior before you started mucking with it?
Hi ! Finally an answer So i used it for about 3 days and i really can tell that it is the same behaviour
My fear is that it may be related to hardware .. I am gonna try to flash the latest samsung stock firmware (with its csc and modem) ?
Anyway any idea ??

In general I'd say it's worth getting the phone to "current" stock, or as close to it as possible, and seeing what kind of situation you're in (i.e. if the behavior disappears or changes in any way). If you're seeing it on every configuration, it seems reasonable to suspect that it could be a hardware issue -- especially given that you got the phone used.
Perhaps someone else knows of a more definitive test you can try.
Hey ! Thanks for the idea ! already flashed the latest samsung firmware and same problem .. i stayed in touch with the guy that sold it to me so he took it back to samsung sav where his friend (who work there) told him that this is a famous bug in the i9505 4g serie and that the only solution is a
nvm restore (something like that). Of course he'll do it for free cause we agreed that if a problem come out he'll have to solve it on his own.
Anyway, i hope to get it back tomorrow or monday ! I'll let you know what happened as soon as i get it back !
solution?
Were you able to solve the problem? in case u were, how? i have the same issue sometimes i have 3g network, then it goes to gprs then edge, sometimes when im connected to wifi i cant receive calls, but i can do calls, any idea?
So I am from Canada and picked up the exynos version from a Korean seller on ebay.
Model number sm-n910K I actually have a huge problem. When wifi is turned on phone will reboot whilst in sleep mode after about 5 minutes if I turn off wifi it works fine. Note this happens even if I am not connected to a network the radio just has to be enabled. I am out of options I might rma it to the Korean seller but I think I might have to open a case with ebay, as these guys are being very difficult here is a video attached. I filmed it for 5 minutes but only recorded the last minute. http://youtu.be/ahLB0A2pCOM any help would be super appreciated thanks guys. I am at a loss whether this is software ie corrupt modem from improper driver installation at factory or just a faulty modem things I have tried already.
1. factory reset + cash wipe
2. Reinstall firmware using kies
3. turned off automatic scanning
4. turned off download booster.
The only thing that works is keeping wifi off. Any suggestions would be appreciated thanks.

Hey, I also have the SM N910K. What network are you using it on?
I have that version as well without that issue. Can you grab a picture of your About device specs?
Hello there i got same version SM-N910K i didn't have that issue with wifi , but i got battery drain , i live in uk and the phone keep searching for LTE- A ,
N910C with the Samsung SoC
I have the same Issue, i live in the US, I was in Malaysia and manage to get a N910C with the Samsung CPU, when I set the network to LTE/WCDM/GSM (autoconnect) it keeps serching for 4g networks, and it does not switch to lower networks even if available, which causes a huge battery drain, i had to set it down WCDM/GSM for it to get data. I did not have this issue with my note 3 which i also got in Malaysia last year, btw, the note 3 came with qualcomm cpu, and that leads me to believe there is a problem with the modem on the samsung SoC.

Hi! i found a solution where you can force your phone to go to GSM Only, WCDMA only or your preferred network type. In your dialer app type: 319712358. It will ask for a password and the password is 774632. And voila you can now choose what type of network you want to use. This will help with the battery drain.

Its most likely a hardware issue as you tried flashing stock firmware. Did you try flash stock modem?
