hi there, i have a problem after i flashed custom ROM, the phone gets singal, but said emergency calls only, it's able to search network and i can choose network, but when i try to make call, it said not registered on network, i tried to flash different modem but still not working, any clues about it?? (it shows valid IMEI and serial number, and baseband ver: n7100dxdmf1 network: telkomsel(my current provider) service state: out of service))
I am with the same problem. I bought a Galaxy s4 i9505 from Amazon and the phone has full signal on GSM network, but when I try to make a call appears the same message always... Not registered on network.
I flashed another ROM but the problem can not be fixed. I have read everything about this problem on Google and in this Forum, but no one fixed this problem. I am in Brazil now. Sometimes the phone works. Sometimes not. I am afraid if this could not be a hardware problem. If someone can help some people are with the same problem.
What I already did:
- checked the sim card in other phone and it works ok;
- flashed the original ROM for a brazilian ROM.
I do not know what to do anymore.

Locked phone that your problem,you must hack rom or search code and unlock your phone.
But the phone works sometimes. I do not understand a lot about it, but I thing that if the phone is locked it should not work anytime, or not?
Today I am with full signal on GSM network (and I can register in the network. In others days it was not possible) and it is working in my home. But when I go to other place outside and walk with the phone in the car it not works properly. In this case I just have none or one point of signal and the message of emergency calls appears again. :/ On WCDMA it works SOMETIMES too, but with one or two points of SIGNAL only. Do you think that it is because the phone is locked? By the way, it's the i9505 model. It should be unlocked. I bought it as an unlocked phone to work in Brazil. It is the international version.

One more information: the phone now is working ok with GSM network, but when I change for WCDMA I only got one or none point of signal. What it can be? :/

Hey.. there may be a problem with your network provider.. happened to me too...
I was using vodafone india and i had activated 3g on my n7100.. then i couldn't change to gsm mode. Then i chose another operator (airtel india) and now i can switch to gsm/wcdma irrespective of ny current data pack (2g or 3g)

I also thought that it was a network problem .. .. I tried Vodafone sim and docomo sim(working in other phone) ... but on my phone It say either no service or emergency call on both 2g and 3g
I bought my phone from Japan and I am herein the Philippines and I noticed recently that when I am connect to mobile data, the logo shown is "R" meaning roaming, no 3g or lte appearing. What must I do to remove it from roaming? I tried turning roaming off but i can't connect to internet. When roaming is on only R and no 3g icon, even if mobile data off the R icon is still present.
If I am to root this or flash to remove docomo software, what must I do then? Please help

On Z1 board, there have a guy who bought a JP model of z1 and he tried to flash a HK firmware to replace the JP rom and fix the LTE problem and works. So, I think you can try but I don't promise, make sure your phone is not sim locked.
And there is two z1 compact of JP models available in JP. The old one is Z1f(SO-02F) and new one is Z1 A2(SO-04F). I think there is no different, SO-04F just got more color and the camera software supports 2K recording(but still no 4K ...lol).
It's just a suggestion but a more descriptive thread title might get more responses...

I hope that it will work. I haven't tried rooting and flashing before so I am a little scared about it. But i don't see any ways to do this. Thanks a lot man!
I hope somebody can help me or can share if he / she is experiencing the same issues.
After searching the web, posting to sony forums, calling support .. w/o any result, maybe someone here has an idea what is going on.
Issue :
At home I have 2 Sonys C2005. One on Official release 4.2.2 and one currently on Cyanogenmod 11 (flashed with the latest firmware available on 7th. September) The first SIM is from Hutchinsons (3 or Drei) in Austria and the Second SIM is from O2 Slovakia. When I switch on the 3G Data trafick on Hutchinsons the phone starts restarting randomly (every 3 to 5 minutes) When I change to GPRS (Edge) , or when I deactivate the Second SIM (O2) then the Phone is working fine. I did NOT had this issues with other Providers. I was before at Vectone Mobile (the second SIM was always O2)
As I wrote before I had tried this 2 SIMs in the second phone with Android 4.2.2 and there is the same issue, the phone starts rebooting. I have called Hutchinson support, they replaced the SIM, checked the SIM profile all is OK. Sony support blames Hutchinsons.. so no FIX on this side either. I hoped custom Android distro could help, but It did not -> CM11 with 4.3 Baseband
I think it is a bug in baseband. (If I understood it correctly CM11 is build on 4.3 Base)
Thx
exact same issue
Servus,
Just bought the phone in austria have a drei and a hungarian sim, same issue with 3g. The phone just works fine when in hungary with 3g enabled on the hungarian sim. Have u maybe any followups on the issue?
I am in a fix here!!! Since long I have been facing this problem wherein, whenever I switch to 3G/4G mode, my phone looses network forever.. It seems to work perfectly fine in 2G mode.. I tried everything.. playing with radios, factory resetting and all the other help that I could get but in vain. I thought it is a hardware issue and since mine is an imported one, and I don't have warranty, I was avoiding to take it to a repair centre.. A week back, I went to Malaysia for a trip, and as I put a local SIM, my 3G starts working perfectly fine... I thought it could be a radio issue and as I came back to India, to my surprise my old local SIM was working fine in 3G mode yet again!!! I thought somehow my problem was sorted!!! It worked for 2 days and it is back to the old problem now.. no 3G whatsoever!!!! Please help me guys!!!
I was just browsing and I read an samsung user facing the same problem.. The carried switched his normal SIM to USIM.. and it started working.. could this be a valid issue?
try this.

If changing the settings in Phone Info did not help I have to agree that you need a different sim or different APN settings.
The same SIM works with the same APN in other phones... and even if it was an APN issue then the data would have been a problem.. But i don't even get network in 3G..

Post as much detail about your problem, if you want to get help.
What version M8?
Is it modded (custom ROM, root, s-off) or stock?
What region/carrier, and more importantly, what bands used for 3G and LTE?
What does it say for OS number in bootloader screen?
You've verified the SIM works for 3G and/or LTE on another device?

According to the following webpage, the 3G band used by Airtel is Tanzania is 2100 MHz (900 and 1800 listed are only for GSM/2G): http://www.worldtimezone.com/gsm.html
As this webpage also lists " 4G LTE TTCL" I will have to assume you got the info from the same or similar website. And that doesn't tell us what band your carrier uses for LTE/4G.
The 3G band 2100 MHz is supported by your current firmware. Make sure you have properly input the APN info for your carrier in the phone's settings.
LTE is trickier. Even with the proper band support and APN, you might not get LTE using an M8 version not intended for your region/carrier. But 3G should be possible.
I did but the 4G symbols is showed on the network bar once in a while. And it does not last long when it shows up!
For the TTCL sim card i can not access the network at all since it does not allow 2G services!
The same here. I face the problem yesterday =)) LTE icon show for the first time and then after a reboot, 3G and LTE signal gone forever =)) Now Edge only. Trying to fix it.
hello, friends. Specially those who are worried about the so many problems with signal moto g5 users face. Im here asking for help. i have a moto g5 (cedric) i was working almost fine with oreo stock. i say almost because some times when i lost signal it didnt recover like any other phone woud, i had to reboot. now from almost a week ago i had lost signal and now i only have 4g. no 3G and no 2G, so no voice calls going out nor incoming ones. i ve done hard resets, flashing stock 7.0 and going back to stock 8.1 and nothing. on saw 3g for a little moment coming back to oreo. i also flashed carbon rom wich is android 9.0 to see if a custom rom helped but it didnt. i only have internet now and sms. and this is very frustrating. ive checked persist folder and everything is correct there. i have my imei right, this phone is like new but not being able to call is like not having a phone at all. also why i have to reboot to recover missing signal? is just a pain. this moto phones are really problematic when it comes to Signal management.
things to consider too: im currently on stock oreo, just rooted to be able to check if persist folder was correct and to backup efs folder. also my operator uses 900mhz band as 2g and 3g wich is an european frecuency not common in latin america. maybe that has something to do with problems im facing. the rom has cedric_latam_cust as the baseband. can anyone help me find one frome europe? im wondering if flashing one from there could help. the weird thing is that it was working before with that baseband.
so many people losing 4g, i could be glad if that was my case and had 2g and 3g only with full internet and calling capabilities.
im sorry i know it is a little bit too much information. but i really need the help

You could get your country firmware from here.
https://mirrors.lolinet.com/firmware/moto/cedric/official/
And don't flash older version firmwares as it will brick your device.and you should try a different sim card in your device to know if there is a problem in sim card or the device.

Thank you friend. I was able to download and flash an euro rom. Just to find that the baseband was not changed after flashing it. I even tried erasing modem and reloading non_hlos but I still have latam baseband on settings.

Not at all. I'm still having 4g only. As I mentioned before, in status it is still showing the same baseband that was in first place. One from Latin America. But I was trying to get it changed to an Europe one by fishing a new rom from O2. But it didn't change.

Maybe you should try pixel experience ROM(pie) or retin firmware as I was on retin and I got many choices such as Europe, United States, some frequency. Maybe you should try pixel experience first as it going fix network problem many times, then you can try retin firmware.

In my country we have 3 mobile operators. Movistar won't work (don't know why), the other works perfect on my phone. Mine from a week ago only work 4g. This afternoon it worked 3g but when I rebooted it stopped. Only 4g again. So no calls.
The first screenshot is with 3g and no signal
The other 2 is when rebooted having activated 4g

It seems the problem is API as you are getting 4g but no calls then it could probably API only, try editing the API or creating a new one. You can get the API configuration from the internet or the device which you get calls.

Did you try a different sim card in the device, does it working??? And does your service provider support LTE over call??? If it doesn't then change the preferred network type to LTE/CDMA/UMTS auto(prl). And switch your sim card to sim slot 2.

I haven't tried another from my company. But from other it does work well. Mine doesn't have lte over call. So when I try to call it switches to 3g and right there loses signal at all. I have to restart the phone to get 4g again
