Please, Please, HELP ME !!!
I looked all over this forum and on the net to try to find a solution to my problem, but I couldn't find anything that relates to this issue.
When I go into Mobile Networks/Network Operators, the phone starts to search for available networks. When the search is complete, I select the network I want and then I get the following message: "Unable to select Network/Select Automatically. Unable to connect.Try again later." The only way I can connect to my provider is to reboot the phone. Because of this, I am unable to use my phone in roaming either. It looks like my phone fails to connect to any mobile networks manually.
When I put the SIM in a different phone, the error is gone, so the problem should be with my phone. Could it be a modem or a ROM issue? Don't know.
The phone is rooted, with Android 2.3.5, Baseband: I9100XXKI4. Kernel version: 2.6.35.7-I9100XXKI4-CL611039 [email protected] #2.
Please help me. All help will be greatly appreciated.
Thank you

Already tried to change modem/
wipe the hell out of your phone/
reflash the Rom?
Almost always helps
Set network APN manually do not use search /auto and see what happens .
That can be followed by backup of data and factory reset .
You can also check you have correct CSC for network/location .
Next would be to flash another modem KI1 for choice through Odin or from the zipped modems post through CWM .

All Fails you can do the following this will bring the phone to an acceptable warranty return state if it does not cure the problem .
....................................
Clean Slate for those that balls up the firmware .
Backup data first if phone is working .
Boot CWM recovery
Mounts and Storage
Format cache data system sd card .
Remove battery
Boot to download mode
Open Odin
Install correct stock firmware .
Still problems use usb jig to set rom counter to zero .
Return to service centre .

Thank you jje,
My current CSC is this: I9100OXAKI4.
My location/network is this: Romania/Vodafone
Roaming in Hungary for example still does not work. Could the CSC be wrong?
Thank you

He should work with I9100XXKJ3
Thank you umarian,
I will try to find a new firmware with the right CSC and flash my phone again. Any quick links you might know would be much appreciated.
Then, I will check later today if roaming works and will get back here with the results.
Thank you again

I had the similar problem since last week: The sgs2 has been working with local operator Telia for about 4 months and suddenly it could not register on the network after I have set it to airplane mode several times
I put 3 other sims from the same operator in my sgs2, all of them do not work, and they all working fine in other phones
I put 2 sims from 2 other operators in my sgs2, they all working fine
So it seems this sgs2 only does not work within Telia's network, but I gave Telia support my IMEI number, they say that number is not locked or blocked in their network
I tried manually select network from the list, but get immediately back a notification saying "unable to select network", not like in a working phone, it takes several seconds before getting a confirmation from the network
So I guess some old denying answer from Telia is cached in the phone, and everytime phone send the register request, the cached denying answer is read. unless I can clearout this cache, there is no way to get registered with Telia
I went forward to wipe/factory reset/flash another rom&modem, all did not help. I guess these cache information is not changeble through normal flashing process, maybe in EFS area or somewhere else
Anyone can help?

I'm sure this is not your situation but my provider was down for the days but when I called support they swore everything was fine and trouble shooted my phone.for what ever reason their Sim showed every provider in my area as them.(as it in network search all providers looked like my provider). While the phone tried to connect to the other providers it was rejected as "unable to register on network"error. I did not figure out out until I checked network search with a different provider Sim and my network provider was no where to be found until they got the system back up in my area.

Thanks, I always flash stock roms and csc for the phone, and tried twice, I believe the data which caused the problem could not be touched by the flash process
Now I put another SIM from telenor in the sgs2 and try to manually select the Telia network, it took more than 30 seconds and returned a message saying "unable to select network, select automatically", and then it select home network (telenor) successfully
However, if I manually select other non-home network (3, tele2 etc... ), it took about 5 seconds to get that message
So, I think that 30 seconds waiting actually is a system timeout period, there is no communication to/from Telia network during this period
The strange thing is that even reflash the rom/kernel/modem do not improve the situation, where did the android system store the settings of network operators so that even a full flash of the phone can not clear it?
I'm going to do some adb logging today to see what is actually happening there...
The Current Problem with my s3 is that it cannot register on a network. It shows Selected network Unavailable
My phone i got it second hand, It used to show a Tmobile Start screen beofre i updated it.
I flashed my phone using odin and loaded firmware with baseband version i9300DDLJ1 . I think this baseband version is indian based. After i flashed the start screen started showing Samsung insted of Tmobile . Initially when i flashd the IMEI got changed. Later IMEI was corrected from a Mobile shop using their STP box
So soon after i flashed , the phone cannot register on network. I messed up with the EFS folder i think . I dont have any backup of EFS folder
The current Situation is IMEI is corrected , The phone shows list of all availalbe network when i search manually . But once i select my home network it shows selected network unavailable. I tried to restore/reset the phone several times . Tried with different Sim card also. No use , still it cannot register on to network
My Conclusions
EFS Folder Is messed up
IMEI is Corrected Using STP box
Base Band is i9300DDLJ1
Originally Phone is Tmobile Based
Phone Variant is GT-i9300
Problem is Cannot Register to network
check out other sections and pick one
somebody please respond. :cyclops:

Solved using z3x samsung tool pro
Enable usb debbuging, connect to your pc using usb cable, root your phone , start Samsung tool pro, select com port, go to repair tab and click on patch certificates. I've tried all other solutions I found on different forums, bricked the phone several times, but this did the trick.
I flashed my I9300 from Carbon rom to Omega Rom v56. Everything is working perfectly. Just the operator shown "No Service", Network shown "Unknown" and my operation shown 45400 into the System Settings －> Connection -> More networks -> Mobile Networks.
The phone can calling, SMS, 3g data connection and IMEI all those working normally. Just it cannot show the operator name.
May I know does it have any solution?
Thanks!
Not all roms show the name .
Try setting the APN yourself .
Probable you have wrong CSC .

I have tried all your suggestion. After changing the CSC, just the "No service" changed to became blank. But the Name of operator in mobile network still be the same.
Anyway thank you for your advice!
Hello All,
I have a Samsung Galaxy Grand Quattro (1 year old), which suddenly started showing "Emergency Calls Only" message with both SIM slots. No matter what SIM is used new or old or any provider it simply dont connect to netwrok. Other symptions are:
Singal strength is good.
Shows all available networks in manual search.
IMEI is valid and not stolen or spoofed. imei info shows everything alright.
In status shows Network = Unknown, Service State = Out of service
Things I have tried:
Factory reset, hard reset from recovery, data wipe etc.
CWM with custom roms like Trans-K and TransWin
Rooted and changed CSC type from INS to INU
Installed latest official firmware from SamMobile
But nothing helped till now. Please suggest what to do now. Service provide says problem is with your phone and SIM is perfectly fine works with other phones.
Thanks,

SIM card problem reselect network take out sim and insert again
Hi, i recently flashed an A10 with the stock firmware (I downloaded the one that matched my country), and everything worked great, except the phone can only make emergency calls. When i insert the SIM card it detects the mobile network, but it doesnt seem to be able to select a network operator (neither manually nor automatically).
I flashed the "free" firmware (the one that isnt locked to any network provider), and It detects the provider that matches different SIM cards and sets up the APN (i also tried manually setting them with official guides), but doesn´t connect to the network and says that it "can´t connect to this network right now, try again later" when i try to select the network operator (IDK if operator is the right word, my phones are in spanish, and dont know which word android uses on english)
The baseband is correct, but when i looked up the IMEI on an IMEI info website, it matched with a NOTE 10 instead of an A10.
This is a friends phone, it was non usable (wouldnt boot), i didnt back up the EFS partition because im a dumbass, but i think the reason it didnt work was because someone else tried to flash a firmware (maybe a note 10 instead of A10), but he says it just stopped working. I am yet to try to flash other network provider´s firmware (the one it originally used), but i was told any that matched my country should work.
WI-FI and mobile network both work, and it detects the SIM card.
Thanks in advance for any help you can give!
Have you tried with a different SIM card?
