I can not have more the carrier signal!

Help! Since I installed the Android 5.0.2, can not get carrier signal! Not 2g, 3g, nothing ... the message that appears is: "No Service".:crying:
No can do call, says I need to disable the "Airplane Mode", but I'm not in airplane mode! not receive SMS. Nothing!
Already tested my SIM cards on other devices and it worked!
Need urgent help!
Since it is a version of testing, will be a bug?
I live in São Paulo, Brazil.
Sorry for the bad English!
Sorry anything, I'm new here ...

Stock ROM.
I believe that is not from India, why it in version says at the end: "timbr" ... but do not know.
If India really has problem?
Why wore CM11 and took well ... and now I'm back to CM and has no more sign before and had ... :crying:

Install stock 4.4.4 again, if not work after this, maybe you lost IMEI, you need send phone to motorola assistance.
I don't lost the IMEI!
I dont lost the IMEI!
Yeah, see the screenshot!
What I do now?
Modem files...
It has something to do with the modem files?
I researched and researched, I discovered that the version that was installed in India, so I'm no signal, so I'm downloading the firmware Brazil ... proceeds?
Thank you guys!
Thank you guys! :highfive: :highfive:
I managed to solve my problem!
It was why my ROM was from India, so could not have signal here in Brazil. Now installed the original Brazil Stock and returned to normal. I thank you all for your great attention! :good: :good: :good:
Moderators can close the topic, thanks.

[Q] I9300, after flashing stock ROM, full signal but emergency calls only !

Hi. A old newbie here with a big problem, not solved by a lot of time lapsed, forum topics etc..
I have a SGS I9300.. Just got it a few weeks ago (2nd hand). Everything was fine, battery drains fast but doesn't matter now.
It had an modified TouchWiz rom which after a wipe data/cache still had SuperSU and I didn't like it.
I had a old stock ROM in my PC (from my old I9300, which worked fine 1 year ago, 4.3 Romania -Orange). I flashed it through ODIN but the problem is that I have signal bars, I can choose between HSDPA/GSM connections, I can register to any network but in my carrier it says The selected Network (RO ORANGE) is not disponible or smth like that.
I went to a GSM Service, they made it work but I didn't like that modified ROM, I want a Full Official Stock TouchWiz ROM for my old S3.
I paid a lot, I don't want to go once again to repair it. IMEI and S/N are good. When I received it from Service, it had USB Debugging ON. I think Z3X will solve this but I think it's not free to register..
Hi

Good luck!
Sounds like your phone has modified/damaged efs and must have patched modem and kernel to use a stock firmware.
Take it back to the GSM Service and ask them to repair the efs properly, so it works on 4.3 without patches.

Hm, I tried a lot of things to repair it, but I did worse. The IMEI became generic (0049), the S/N was modified.
After a lot of time lost, looking on XDA, YouTube, trying to repair it... I found that the only viable solution was to go with it at a GSM Service. You can't modify or repair your IMEI without a box (z3x). I finally managed to fix it for just 9$ ( I was thinking to buy a new motherboard -> 50$ )
Thanks for your reply

I have the same problem. The IMEI and SN are good, but I can't call. I was on CM11 before and then I put phone accidentally in flight mode and flashed Blekota v11. Was not able to make calls anymore. Then I used ODIN to flash back to a Stock rom what I wanted to do in the first place. But still no change. Do I need to flash a different Baseband version?
Please help me, what can I do?

Yes you can flash different modems, a lot of people solved the problem with XXEMG4 modem, but in my case.. Nothing seemed to work.
I have again the same problem, IMEI and S/N are good, Emergency calls only. I think i have EFS V1 but my rom is fully working with EFS V2.
You should better go to a GSM Service and see what you can do with yours, don't try because you can lose your IMEI and S/N and then the single solution is to repair N/V data IMEI and S/N with Z3X box at a service.
Thanks, it worked with the patched modem and kernel. I used this procedure: http://forum.xda-developers.com/galaxy-s3/help/guide-emergency-calls-problem-siii-i9300-t2752541

RE
I had the same problem, while i was trying to flash F103 Pro's Roms for F103 but didn't work and ended up Flashing the Stock again but i had the same problem too.[ LMAO]
Using MTK Engineering Mod App from Play Store helped me.
There are couple of helpful videos on how to do it.

Do you have nvram.bin backup of your f103, that's what I need to scale through with this. Can you please do a nvram backup for us to get us off this nightmare because mtk engineering tool didn't help too.
Thanks
