After flashing new ROM to my device I get 'emergency calls only'. After I tried searching all the threads i get similar solutions which don't work in my case. my imei remains intact and i still don't understand why i can't connect to network.
It started with galaxy S3 i9300 aftet flashing stock ROM from sammobile which fortunately was solved by Ariza Patch.
Now for my GT-S7580 I lost mobile network after flashing cm12.1 by Sandpox and I cant find any app(like Ariza Patch) to restore it. I also tried a stock ROM from Sammobile.com but i still don't have network. I tried post on the related threads but my problem is not solved yet.
I tried all these solutions but none seems to work:
-searching mannually
-turning radio OFF and ON again.
-switching phone off, removing battery and SIM card and on again.
-turning flight mode on and off
Please help on any way to get my network working. My Carrier is Safaricom Kenya

i recently got a Galaxy s2
but i am having some problems with the network (have read many threads, but no fix so far)
so, the phone was 2.3.3 version
i flashed via odin stock roms to 2.3.5/6 version
but - no mobile network, changed different roms and on the KI3 i get 2-3 days using the mobile network, and then it loses the network...
any ideas what i can do?
FIXED
Try flashing different modems until you find one that works well for you. There are a ton of threads on here which have links to modem downloads (and many of them are hosted on sites that still work), search for them.

Click to expand...
Click to collapse
i tried 4-5 modems...and not working..that's why i said i have read many threads
obviously i have to flash all possible region modems
Return phone to service centre .
jje
Update:
so i flashed few more modems (like 7-8)
and i can see the signal strength is ok -around -60/-70 dBm...so obviously it's ok
and again for a couple of hours network was fine then,,,disappeared
*can't get it back to service center
other ideas?
Has your ime changed?
Does this only happen with your sgs2 or does it happen if your sim is in another phone?
Are your apn settings correct?
Sent from my GT-I9100 using XDA App
IMEI is same, no change
the APN settings are fine
the sim card works perfect with other phones, that's why i think the problem is in the phone
will try with other sim card in same phone and will post result. while waiting suggestions
What model do you have? Check on the sticker under the battery. Checking in settings doesn't show the true model. Eg, I have an I9100T but in settings it shows as the I9100 because I use a I9100 rom. I get crap reception on all roms until I flash an I9100T modem.
Sent from my GT-I9100T
it's a gt i9100
so same as in settings
still no other sim card to check
did you try the kg9? in which modem you were in 2.3.3? did you try to return the same? if it does not work I think it's best to bring your phone in for repair
i think no, so i will give it a try
* i am in france btw - do you use the same modem?
with my andy rom i'm in LPB modem and it work very fine but before, i was in ki4 or kg9 and i don't have problem with it
So FIXED
obviously it wasn't a modem problem, but sim card - wasn't working with no matter what sim card. So i did few times the hard factory reset and used again Helroz application from the market, and on the 3rd time, it worked.
10x for the help and the advices guys
what leaves as a question is : am i going to be able to flash custom roms, and what is changed after the use of Helroz application, so i can do backups?
I flashed a custom yesterday and phone started up good and everything worked except I cant connect to my network provider. I tried resetting the network settings and everything, I restored back to my stock rom and still cant connect to my network, IMIE number is there and everything. Dont know if I screwed the SIM card up when i flashed the rom or not but its getting frustrating....anyone with help would be awesome...thanks
Did you try to start "from scratch" with ODIN ? This is the only to make sure the issue is hardware/firmware related.
If yes, then maybe you are a victim of the bug described here: http://forum.xda-developers.com/showthread.php?t=1852255
Also any info on the ROMs before/after would help.
After attempts to unlock, the phone can no connect to any network. On phone everything works fine, see all the network but can not connect, says that only your emergency calls, I tried hard reset, flash new sammobile firmware , change SIM, but I still have the same problem.
IMEI is not chainged. Please help
Usual wrong modem wrong CSC Wrong APN settings .
Hi guys,
This is my first thread and I've just recently began rooting and flashing roms etc.
I'm sorry if this is a duplicate thread but I searched the forum and found nothing. Here's the thing:
I have a Samsung GT-i9300 ( international version ) and after the first flash I lost my efs folder.
Which did not only mess up my IMEI. It messed up bluetooth, connectivity, wifi adress and the phone lost it's identity.
I took it to a " technician " who said he could fix it. He restored my imei, but the network wouldn't work. So he put another IMEI and voilá!
The phone had connectivity and worked perfectly. So he told me that my phone's imei was reported as stolen because the network wouldn't let it connect. ( and I have had this phone since it first came out of the box and I never reported such a thing. )
He then said the police would have to be involved to verify if i'm the owner so I just told him to put a new imei on.
When I picked up the phone it was working fine. Full connectivity. Then I flashed a rom and lost my efs folder again.
Luckily I had a backup of the imei, wifi, serial and bluetooth adresses. Which were sucessfully restored.
But still, no connectivity. So I googled it and finally found a solution! The problem is with the Baseband.Basically the phone lost it's baseband files, without which the phone cannot connect to the network, and when the " technician " restored my imei, he copied the whole EFS file from the dead phone. Which then replaced the missing files and the phone worked. So my IMEI wasn't blocked, my EFS file was corrupted and the baseband files were missing.
I used the Ariza patch. And voilá, the connectivity is back. But after being turned on for about an hour, the phone has a pop up which says it's not registered in the network and it must restart with a valid sim. And it's a no option pop up, you are indeed forced to restart your cell phone which is annoying because it shuts off at night and operations that take more than an hour are impossible.
But still, after 2 days, the ariza patch stopped working. The phone is in Emergency Calls only now and it doesn't detect the sim. But it's not blocked, it connects to the network.I read that you could flash the modem files to fix this aswell. So I downloaded the modem file for my phone, from my carrier ( VODAFONE PORTUGAL ), from one of the threads here. It didn't work.
Now, this is the question:
Is it possible that it didn't work because my new EFS file is from a phone based in the UK and my phone is from Portugal?
Can it be a sim software problem?
Also, is there any solution found other than the obvious which I've already exhausted ( flash stock rom, wipe cache, etc )
Thank you an Advance guys!
I have a Jiayu S2 double-SIM phone, running the most up to date official ROM (4.4.2).
This ROM had a couple of bugs (no GPS and no notifications to external devices such as smartwatches), so I wanted to check other available ROMs. Using the Flash Tool I have tried a couple of the ROMs in the needrom site (https://www.needrom.com/category/jiayu/s2-jiayu/). In particular, a couple of versions of the official ROM, another ROM known as Salamander, and an unofficial port of Cyanogenmod 12 (in which the camera was not working).
The issue is that, for some reason, at some point my phone has stopped getting phone signal. The SIMs ask for the PIN on startup, but there is no signal. I have reverted to the original ROM; plus done a factory reset, and I could still not get signal.
The APNs for both SIMs are fine. Then I have realised that the IMEI was empty. Luckily I had it written down, so I have installed Xposed and the Device IMEI Changer, with which I have been able to restore the IMEI. Now I can see the IMEI on the Settings - IMEI information, as well as with *#06#.
But still, now with the original ROM, and with the IMEI restored, I still cannot get phone signal. I have tried setting the phone to flight mode, restarting, selecting manually the network... When trying to manually select the network I can see several networks, but the phone will simply not connect to the one it should.
Any idea on why could it be that I cannot get phone signal? Thanks.
After trying everything, including restoring the IMEI with Xposed, I have finally managed to restore cell service by restoring the IMEI with this tool: https://play.google.com/store/apps/details?id=com.cryptotel.chamelephon
