Hi,
I´ve been having a serious issue with my phone.
- I´m not using the phone, people call me and get a busy signal.
- I´ve tried calling my self from a landline and realized this is true.
- I´ve tested calling my home´s landline and got a weird beeping sound and then the call was not completed.
- I´ve rebooted the phone and the issue was fixed, but after a while it reocured.
Any thoughts on how to fix this?
I was just wondering if its a SIM issue (rather than phone). Maybe try a different SIM and see if there's a different result?

- I´ve cleaned the SIM card and the SIM card slot, put it back in and made a couple of teste. I keep getting the busy signal even when the phone is not being used. Now even after I reboot the issue sometimes happens....or if it doesn´t happen it starts happening after the phone goes to sleep.
Could this be the phone´s modem? This is a serious issue.
You can flash a new modem from the modem thread .Or ask for a new sim card .

I got the lastest "Test Mode" firmware from the program "Check Fus Downloader" for you.
Product Code: GT-I9100LKAEPL
Latest firmware: I9100XWKF3/I9100EPLKE4/I9100XXKE7/I9100XWKF3
Is this the correct one??? If so you could try the following if you already have root and CWM Recovery installed;
Type into your phone dialer *#1234# and write download your existing 'Phone' (Modem) version, just incase you wish to reflash that.
[MODEM] Main modem XX versions flashable through CWM
Immediately before flashing, I suggest you take nnote of signal strength; Phone Menu / Settings / About Phone / Status, you can then compare.
Download the closest matching modem and flash through CWM Recovery. The closest I can see is XXKF2.
If you still have no luck, could also try the latest one as well. Be aware for any change in signal strength, quality, not obtaining 3G, H, H= etc.
Hope this helps
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...
Hi. I've done something stupid xD. When i tried to flash kernel to stock i didnt exclude baseband and now i have (no service) problem. In about phone shows baseband version 2.1.71. Whats more interesting, phone finds network operators normally but when i try to connect (phone dont connect automatically :/) shows "your sim card doesnt allow connection to this network". Thanks for any help in advance .
So my sgs3 had stock & rooted 4.3 on it. I've decided to "upgrade" it and give it some MM love with cm13. Unfortunately just after first boot during setup it says there is no sim... Also, modem and IMEI was unknown.
I have flashed stock param and got back modem and IMEI info but phone still says no sim...
In mobile network settings in prefered network type it says "Invalid Network Mode (-1). Ignore" <- what does it mean?
I tried flashing latest stock via odin but after waiting over one hour for 1st boot I gave up...
Can anyone help me?
I have sm-g360h duos. I had rooted my phone through kingoroot and later decided to unroot and even unrooted but my device recognized root during software update so I flashed firmware (downloaded from sammobile.com) through odin but after flashing a firmware, 3G is not working in my device.Later I found that firmare was corrupted during unpacking process. & I also flashed another firmware but problem remained same. I often and often checked a network and setting.There is no network and setting fault.While I change my network mode to cdma only, No service sign appears in signal bar. Call sms,2G everything running well and imei also okay but 3G is not woking. Please help me
Flash TWRP and Use a Custom ROM.The fault Is In The /system/bin I had that.
