Hi everybody (and sorry in advance for my poor english) !
I am having exactly the same problem as the OP. To explain the situation in a nutshell:
I have the SM-G800F, for about a month. It worked fine, until I moved to the other end of France (it probably has nothing to do, though). Passing on the highway, "Emergency calls only" showed up while I was looking at my emails. The problem is that things never got back to normal.
The situation :
As I said, the same as the OP. When I turn on my phone or I go out of airplane mode, my phone tries to connect to 2G, then 4G / H+. The process takes a few seconds, then any indicator (left of network "bars") disappears, and I can't issue or receive calls, nor use data.
But if I force "2G only", everything works just fine.
I was using a rooted 5.1.1.. In the meantime, I tried several suggestions found here or elsewhere:
-Turn off the phone and on again : Nothing
-Enable / Disable flight mode: Nothing
-Remove / Replace the SIM card: Nothing
-Putting the sim in another phone: everything works just fine, so the problem may not be a faulty sim card
-Wipe Data / Cache Data then use Odin to reinstall a stock 5.1.1 rom (I'm really a noob to find the right words, sorry in advance, but my phone says, under the "version number" field , LMY47X .G800FXXU1BPC4 and the ROM I used is named : -G800FXXU1AOG2_G800FOXX1AOG1_G800FXXU1AOG2_HOME.tar.md5 filename
Manual carrier selection : Nothing
-Turn on Data Roaming : Nothing
-Checker my APN : Everything seems just fine
I can't tell for sure but I do not think it is related to my home. My problem began on the road and took the rest of the trip (2h/3h), and even around in the city, it remains. Moreover, my backup phone and the other people on the same network as me (Orange) don't encounter this problem.
So, I'm a little bit confused and a bit worried because of Knox (0x1: /). If you have opinions, advice, guidance, thank you very much in advance!

No, I really don't know what the problem is I think it's something in the phone itself
I've got the same problem too
Did you find the cause of this issue in the end?

Hi !
Not yet ... I have another phone now but i still try now and then to fix my S5 mini.
So far, nothing worked. Some tech guy told me it was a common issue with that phone's antenna. Also read that from several forums.
Still, i read that some users were able to fix similar looking issues by flashing the modem file with Odin. I'm a bit n00b but i guess i'll give it a try.
Any success on your side ?
You can try searching for your carrier manually and choosing it.

Thanks, but i already tried that many many times. My S5 Mini just displays "Network XXX unavailable" (or its nearest equivalent in French)
Did any of you manage to fix that by flashing your modem file with Odin ?
I've tried additional stuff but nothing seems to work. Back to stock Marshmallow. Still loosing radio signal whenever I enable 3/4G.
Maybe the bottomline is "hardware failure" but who knows...
Thx everyone!

Have you tried a deep reset? If it does not works, try a custom ROM...
Hi !
Thanks for your reply,
I did try "Factory Reset" and "Wipe Cache" while in the Recovery Menu (Home+Power+Vol Up if I remember well). Is that what you were refering to ?
But I think I didn't try flashing a custom rom. Could you recommend one ?

Yes I was meaning this. For a custom ROM i can recommend One of the latest with NOUGAT like Lineage OS 14.1

Hi,
I installed Lineage OS 14.1, it's great but the same problem keeps happening. Everything works just fine in 2G, but whenever I enable 3G or 4G, my phone looses radio siglal and switches to "Emergency calls only" after a few seconds.
Any other thoughts ?
Thx !
As a side question, would you think of any way to rule out/confirm the possibility of HW failure ?
Thanks again !
Did anyone found solution for this?
Hi,
I've got the same problem. Tried to flash with Lineage 13.0, then 14.1 and still the same problem.
Anyone help?
Flash the last modem/baseband, did yoy try *#*#4636#*#* ? You can manually select wcdma only(3g) or lte only(4g) (sorry for my bad english)
still not working
When I choose 3G/2G auto connect from 1 line ti go to 4 signal.. so no LTE /4G for now..

Hello,
I have just flashed MIUI Gingerbread 2.4.20-RC3 to my GT-S5570, everything looks great, except WiFi, when I turn on WiFi, it says "Scanning" finds my WiFi and then "disconnected" and again shows "Scanning" for 1 sec and again "disconnected", what can I do?
WiFi Error
You need to revert to your old stock rom, because the drivers for WiFi aren't working. Same thing happened on my mobile phone, when I flashed it with the newer firmware. Didn't really find the solution to this problem, but solved it by going back to my old rom. Hope this helps.
You can also try typing this code into your phone: #*#*526#*#*
It might work for you.
Best of luck.

It is working now, here is what I did: In phone settings I tried to change themes lock screen to other, but unfortunately not default lock screen was way too big (very big resolution) so I was not able to unlock my phone any more, once I found that I can do it pressing back+volume down, it helped to unlock, but MIUI was crashed and stopped working, so I had to wipe all data and cash, to reset default settings, after this, everything works great now.

the same thing was happening to me (on the same rom)>> "fixed" it by reseting the notebook-hot-spot (connectify) I use
[sometimes even a simple wi-fi turn on/off or rebooting the device would help too]
I'm posting this in order to prevent you from doing more drastic stuff :cyclops:

Hi guys
I own a Lg Optimus 2x P990 and I am currently running the JB CM10 Build by tonyp.
In the past I ran ICS builds like Django Manouche and other cm10 builds like Paranoid Android.
The cm10, builds are running very well on my device but there is a possible bug ... I use my phone during the day, and if I send, receive messages I usualy keep my connection with the mobile network.
When I wake up (phone is inactive for several houres) , and I just unlock my phone, the network bar is full, but I can't send or receive messages. When I go into Settings and try to search for a network I get " Error while searching for network ". A simple reboot can fix this problem.
If I don't use my phone often during the day, It does the same. I unlock after a few houres, statusbar Icon is full, but no network available... (so if someone tried to reach me by calling or texting, I can only see it after a reboot.)
The second thing is that I always have R above the network signal, even when I am not roaming at all ...
I tried to change my baseband when I was on Paranoid Android, but that didn't work ...
There is NO problem with my mobile network on the ICS build (like django manouche) , but the ROM isn't fast enough and I like stock android more ... ( I think)
I always did a full wipe, and followed the instructions ... I am on the latest Kowalski Kernel at the moment...
If I erase internal memery, could that do something?
Thanks for your time.

That is strange. I am running cm 10.1 too and I have sometimes problems with logging in to operator after reboot. But your problem seems bigger. Did you tried to turn on/off mobile data (dont know how it's in english version)? And try to change to 2G/3G, maybe that might solve something. Or maybe there is an bug in new Bootloader (if you ran django mandouche and tonyp's), so if that doesnt help to you, try to downgrade to old BL

Thanks for the reply ! My phone came with the old bootloader, and I installed Nova HD CM9 on it and had the same problem.
I need to try the 2g/3g settings...
When the error occures, I can try to turn data on/off all I want .. only a reboot helps ...
Django is on the new bootloader, and worked fine ... So I believe it's a CM problem... ?
I also dialed *#*#4636#*#* and changed to WCMDA Preferred (but didn't help)
Any more advice ?
APN - check it!
also.
try different base band.
try 30b

I also have this problem, tried every possible combination of baseband and ril, still couldn't solve it.
Ended up returning to v30b ICS, where the problem doesn't occur.
Hey XDA,
Before I get a lot of flaming I want to say I did search extensively and wasn't able to find any solutions/people with the same issue. As I'm new to posting in XDA I am not new to forums so I do know how to search.
I just installed Cyanogenmod via the Installer to test it out and see if it worked on my new HTC One. I am unable to connect to 4g LTE and there is no option for this anywhere (just the general Data Enabled toggle). Anyone have a similar issue or know a fix?
I know with my older phones I would flash an non-JB modem before installing CM, but figured I didn't have to with the installer they released.
Thanks in advance for the help, loving the HTC One so far!

Settings -> More -> Mobile Networks -> Network Mode
change that and you should be good to go (mine is set to LTE/CDMA/EvDO/GSM/WCDMA)
might need to disable / enable data / airplane mode / etc but just play with the settings a bit and you'll get it
(for reference i updated my radio manually, and gapps to 08/20 and using the stable milestone 1 release)(3 zips)
had some links for you but it won't let me post them sorry

Unfortunately I've tried all that. I'll have to try a different radio and see if that'll do the trick.

I didn't. I'd constantly switch between the different CDMA/LTE choices and could sometimes connect to LTE, but I would also randomly lose service as if my radio stopped working. Went back to stock and everything was working fine so I'm sticking to that.

Ah, well, I got mine working. I'm on the 4.4 google edition rom. using the nova launcher > apn, then for the settings just named it "Credo LTE" and used apn=“n.w1.ispsn" and mmsc="http://mms.plspictures.com" and type="default,mms"
all is finally working right. for whatever reason, with root and all I couldn't get the apn-config.xml to save. I put an edited file in there but it kept reverting... I also went into *#*#4636#*#* and changed the preferred network type to LTE/CDMA (auto).
hope this helps anyone on credo!
Hi all! I have a droid 4. i just flashed it with CM10.2.1 and then updated to CM11. in both version sms is not working. I type a new text and it fails: i get the red triangle and message not sent.
I looked around and I found it's a common issue and if you remove "voice+" sending sms is available again. I removed "voice+" going to system>app>voiceplus.apk and deleting it as i saw in a thread and reboted, many times. still not working.
then I also went to the *#*#4636#*#* menu and checked the SMSC. I tried both the +39 and the 079193 version but still nothing.
I have to add I'm using the phone in italy over a GSM network. Phone calls and data network (3G) works perfectly!
How can I fix this? CM11 is a stable on this phone, strange to have such a big problem!
Thank you for help!

Installing the patch twice uninstalls it.
Install it again and then reboot.
If you upgrade the ROM at any point in the future you don't need to install the patch just reboot again.
So, first reboot after a ROM upgrade will leave you with no GSM signal but another reboot will bring it back.

I did it and in the 4636 menu I have GSM but still does not get signal...
Have you tried using an alternative SMS App? Hangouts maybe?
So I managed to solve the problem. This is the way:
-deleted rom slot 1.
-recreated a partition in rom slot 1
-wiped everything in slot 1
-flashed cm 10.2.1
-flashed gsm patch
-booted
-flashed gapps
Now everything is fine!

You can try and flash another ROM to see if it's the roms problem, or do another clean (by wiping system,dalvik-cache,cache and data ofcourse) install of your current ROM. :good:

It could be the problem of your Sim network provider. Have you tested it out with other sim providers and see if you can place calls!?
Well in my case it somewhat worked with
*#*#4636#*#*
and then i select the GSM (PRL) and of the radio signal
now its working fine
now i want to know by switching of that radio signal will there be any other problem?
