I believe it is an issue of the APN. All the custom roms i had tried had this issue. But it was only later (Like 5-6 different rom tryouts that i understood that changing the APN worked. For me it was set to "portalnmms" for my sim by default. Changed it to "www". You can try this method. Settings->more->mobile networks-> Access point names

Nope that didnt resolve the issue.
I think you are having a baseband problem . Even if you flash it you will not be able to change the baseband version. I was having the same problem but if fixed it .

Hi Youngers!
I got a friend's Y that doesn't have any signal or service with a working SIM. It only displays an X on top of the empty signal bars. I configured it's APN, and flashed another modem , but it's still doesn't work. Any help will be appreciated.

Try some troubleshooting. Test his sim on another phone and see if it works there.
Is he on a custom rom? Creeds Rom 3.4 had a bug where you cant see the signal even though it has a signal. Can he still send messages even when signal bar is X?
Also, APN wont do anything for the signal, its only for mobile internet browsing with your carrier. Hmmm... are you talking about surfing through your carrier? or basic services like calls and texts?

Thanks for replying! It's running creed's v2. When you try to place a call it says "Mobile Network not Available". I tried his SIM card on an unlocked Atrix 4G and it made a call successfully. Texting doesn't work either. He said when he had this problem he took it to some unlock/repair shop and they failed to state what exactly was causing this.

If all else fails, go back to stock rom or try another rom
(Though I suggest latest stock rom with merruk kernel and superuser opened)

Your phone is network locked or something like that I guess.
Best way to get it solved is to post your query in this thread:

I advise to flash this pack: S5360B_UTLC2_ZTOLC_UTLC1 (open Brasil)
Flash all 3 part (PDA, MODEM, CSC)

hey pal i also encountered this kind of problem before after patching Creeds ROM. What i did was I reflash the rom with stock Galaxy Y via ODIN or after the first successful boot of selected customize ROM. then you will need to apply the CSC depending on what network your country has. like mine i choose either from SMA/GLB/XTE. just dial #272* IMEI code. I hope this will help.:good:
so.. I have this phone parked in my drawer for almost a month and finally decided to seek for online help.
Last rom installed is cm7 (but i've tryed several others cm7.2 cm9 cm10 cm10.1). I've tryed using both the baseband switcher included in the rom settings (where avaiable) and the standalone apk. I live in Italy so I chose Italy in the baseband selection (again.. I've tryed several others basebands just in case...). The sim card is a working VodafoneIT sim card and it is recognized by the phone.
the problem is that my phone does not lock to any network and I see the message "emergency calls only".
I also tryed to flash original sbf from here.
I don't know if it matters but logcat reports these errors:
Code:
E/GSM ( 6427): RIL implementation has returned an error where it must succeedcom.android.internal.telephony.CommandExcep tion: GENERIC_FAILURE
D/RILSWITCH( 2018): RILD unknown at cell -1
E/GSM ( 6427): Wrong network type: 0
I remember that at the time of when the problem showed up the first time, looking on the internet, in addition to the advice of changing the baseband, I found a thread where someone was talking about a possible hardware fail.. but I can't find it anymore.
any suggestion?
thanks
up????
i'm also having this problem
anyone found the fix?
Does the same error occur in stock? If so then I think it's a hardware issue. You could try a different sbf of your carrier and region(a newer one), but I do not think it would help much.

Try with different bands from your country or another country with the same frequencies.
Pull the batery out for a few seconds.
Use the latest version of the standard app (not defy parts).
Regards,
It works for me with a different company of my country
My chip is Personal_AR and with this don't work, but with Claro_Ar works fine...
THX it's make me crazy

More details needed I think.
Has it EVER worked? (i.e. did you just get the phone and it failed?) (just in case "working on Android 5" means that is what is on the phone and not that it WAS working on v5 )
What was the last thing you did before it stopped?
What firmware or ROM are you using?

Change your sim card .
Check your APN in mobile network settings .

This is sounding like hardware issues. Last thing to try would be download and install fresh version of your firmware, just in case something in your set up has become corrupted.

Please someone help me, i was updating my s7 edge duos to 7.0 after that i cannot join network, wifi works well and got signal also but cant connect for some reason shows Emergency Calls Only i tried many roms and with every single i got no network, nothing helps.. when i check dial 06# my both imeis are OK and nothing is wrong with it..
maybe i flashed wrong modem or something and how can i repair it now? please help
Provide more details of your phone , are you using original stock rom ? Or rooted custom rom? You may try changing sim , or wiping cache partition in recovery , if that doesnt work only option is factory reset, also tell if your update was successful without errors ? And use the same firmware as your current region , and also check if your phone is carrier locked , then you need to unlock it to work or use the same carrier firmware.

Hi Bachimpek
Seems like you need to patch your certificate , try to downgrade to 6.0.1 and see if phone can connect to network if that doesnt work then you need to patch your certificate with a box like "z3x" or "octipus"

So , you want to downgrade ? Just download a complete firmware file with all files included and flash it with odin, it will downgrade , if it solves the problem , maybe stay with it instead of nougat.

Don't seems so , you need to repair it in z3x or octoplus box , but if network was working well before update to nougat , it should work when you downgraded again to 6.0.1 , so i guess its some certificate issue , but you may check some setting and try to search networks manually and try changing network type to 3g/2g , 3g only , 2g only. Also try checking different sim cards. If it did'nt fix then you have to repair by box. Good luck

Hello, same problem samsung s7 edge SM-G935FD. restarted my phone and no network. My region is Lithuania and i cant find firmware of my country, what to do ?
I have a Verizon S7 Edge that had version 7.0 installed. After upgrading to 8.0 by Odin I run out of coverage and the Network Operators tab appears off. I have already tried everything and I do not resolve. Even try to go back to version 7.0 and stay the same. Please someone help me. I live in Cuba and I do not want to lose my cell phone.

I tried something new and I have interesting results.
I installed a Firmware U, it is a version of android 7. I installed it by odin and everything well without problems. When I restarted I put the SIM and it told me that I had to restart to configure the options of my operator. It restarted without problem and to my surprise it CONTINUES without Signal. In '' Access Point Name '' the APN of my operator's MMS has been created ONLY and AUTOMATICALLY. I did not set it up, it came out alone.
I still do not understand what problem this phone has. There are several people reporting similar problems with the upgrade to Oreo even in other S7 EDGE models.
Any ideas?????
