Emergency calls only

I have an international unlocked GT-i9250 that seem to connect to any of the networks. It was working fine until I decided to flash a ROM.
I have tried various SIM cards of different networks. It seems to detect the SIM card though. When I pull down the notification drawer, it shows "Emergency Calls Only - Airtel". So it is able to recognize the Airtel SIM card inside. But it wont connect to the network at all, either automatically or manual selection.
When I manually search for networks and select the right network, it comes up with a message it wasnt able to connect to the network at that time.
I have flashed all the factory images starting from 4.0 to 4.3 and a couple of other custom ROMs and none of them seemed to have helped. I also tried extracting only the radio from the images and flashed them using fastboot and that was uselesss too.
EDIT: Yesterday, I flashed the stock ROM using Odin as well. Still no luck.
Is there anything else that I can try?
Nobody? :-/
Same Problem
I registered on the site just to say that I have the same problem .
my nexus 4 was working fine like 1 year untill we cut off our mobile carrier ,
now , when we enabled the carrier back on (sorry for my bad English , I hope u'll understand me)
the nexus 4 seems to recognize the sim since it writes : EMERGENCY CALLS ONLY | MY CARRIER (012 MOBILE)
but i cant get it to work with the sim , the sim works perfect on my moms iphone so its not a problem with the sim .
the sim wasnt cut or anything . and it was working just fine for 1 year . I tried flashing google stock 4.4.4 with a toolkit ,
didnt work . Still getting the same EMERGENCY CALLS ONLY | MY CARRIER (012 MOBILE)
and when i tried to select my carrier manually , like the thread opener did ,
I got the cannot connect to this network . try again later massage .
I honestly tried everything I know .
Im starting to think its a problem with the device and not the operating system .
since i flashed a brand new stock image and it didn't work !

[Q] i747 Wifi not working...fix needed

Hi all, so here's my conundrum...the wifi in my Samsung i747 has ceased to connect to any wifi network. It scans and finds any network like normal but when i enter the password for the network it doesn't connect and goes back to 'saved' instead of 'connect' in the wifi settings menu. I tried re-flashing the stock rom, wiping data partitions, factory resetting and up until yesterday i flashed in the carbon rom with micro gapps to see if it would have worked but all has failed so far....any ideas anyone?
Can your phone make a receive calls and text messages? Can it connect to the carrier's data network?
What bootloader and modem are on the phone?
yes i can connect to my local carrier and make calls...i am also able to get data services. if i use my laptop and repeat the wifi network the phone will connect to it but not directly to any wireless router. how do i find my bootloader, csc and modem info? tried *#1234# but probably how my rom is custom it's not working?
Since everything is working and you have tried custom ROMs.
To find information about your bootloader and modem, install the Samsung Phone Info app from the Play Store.
It's important to know the bootloader before flashing files.

GT-I9192 No service

Hi, I'm having some troubles here with a GT-9192 (Stock ROM 4.2.2), one of my friends brough me his phone which he tried to root (I don't know how or what software did he use to do so) and I think he did something really wrong because now the phone boots as normal but doesn't get any network signal at all. SIM1 doesn't recognize any SIM inserted, SIM2 does but there's no service at all, every time I try to search for a network provider it fails and if I select automatic selection it says "registered on network" but there's no signal at all.
I tried flashing today Bliss 6.0.1 ROM and it flashed nice, booted up and worked as intended yet the device has no network signal. WiFi and bluetooth work nicely.
What can we do to fix this? I did a Nandroid backup of the official Stock ROM on TWRP 3.0.2-1 and I just did a restore. Do you need more info? I'm out of ideas.

Signal Lost after flashing stock .pac rom on BLU Advance 4.0 M (A090L) (SC7731)

Im having this issue after flashing the stock rom, besides the phone goes off and doesn't wake up after 5 seconds standby, but i really want to focus on signal problem before fixing anything else.
imei numbers are fine (this phone has Dual Sim) i checked them after flashing but the issue is still there. the phone recognizes sim at both slots, but no signal.
I tryed to search networks and always says error while searching, so i think modem file which came with the rom isn't compatible with my carrier bands. in fact, it cant even get other bands from other carriers from my country.
i thought i might could use some files from other roms of same brand and proccessor which could recognize the bands from here, but didnt work, when i flashed them the phone didnt even recognize the sim ( and it could do it before) so i flashed previous files.
i've been looking for the really stock rom of my phone (Which is a090L, but i flashed a090) throught most of google, but i could not find anything.
if you guys know any way that at least the phone can see my bands i would be really grateful
if you need any file from the phone just request it i will upload it as fast as i can
