Hi I'm looking for help with my i9300. I had an aborted root, the phone froze during root and eventually I had to restart, I was able to re-install the stock ROM and the phone seems to work fine, apart from one major problem: It won't recognise any mobile networks. The phone won't recognise my network (3), or simcards from any other network. I have re-entered the APN information manually, but this has made no difference.
All other aspects of the device work fine, wifi, apps etc.
I'd appreciate any advice on steps I can take to resolve this.
I have obviously tried standard stuff such as full factory reset.
The phone still displays coverage bars as if it was connected to a network, but when I try to dial out or send messages I get an error message "unable to register on network"
Check the imei number matches the one under the battery, if it has changed then you have major problems without a backup of the efs partition. Search and read for hundreds of similar threads, there is a sticky in the general forum.

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.
Hi,
My unlocked S3 will no longer make/receive phone calls. Searching for (and then trying to register on) mobile networks results in "unable to connect try later"
IMEI code is OK (not starting with 00)
Different sim card- same results
Flashing rom to latest stock xxemg4 rom etc - same results
Now the weird thing is if i add an APN to my service provider - i get data connection (email/twitter) work - but cannot register on voice network
Is this a hardware radio issue? Have any of you guys seen this before? Any advice?

>>>Is it matching your IMEI ???

Reads as you have wrong CSC or wrong APN settings .
Suggest read the Faqs and Guides first .

Could also be your network operator having issues. Can you test your sim card in another phone? (Or another sim card in your phone). You could also try different network modes in the mobile networks screen.
Thank you for your replies.
My IMEI number does indeed match the one under the battery. All APNs have been deleted and then only the APN from my network provider added.
Network says sim/imei is NOT blocked.
Sim works (with calls) in another phone
So - my phone is now a PDA - data connection OK but no voice calls. I guess it must be a phone hardware issue - Odd but there you go.
Again - thanks for looking.

do you recall exactly when did this happened?
any chance you might have installed wrong modem when flashing rom?
It was working fine - hadn't flashed anything for months. Then voice dropped out - never come back on.
Usually if something stops working and you haven't made any changes then it might be a cache or system file is corrupt.
First clear the cache and dalvik, then factory reset and reflash the rom. If it still the same on a clean stock rom then likely to be hardware.

Done all those. Still the same. A little disappointed but shall see if i can get the hardware repaired. Thanks to all for your replies.
I'm here because I have a really big problem with my phone, I can't send any message and I can't call because my phone can't registered on GSM or 3G network. I can receive signal from networks but I can't register on it, when I select a network it's showing a message saying : "Can't register on network now, try again later". The strange things is that it just append suddenly, all was perfectly working about 2 years now. It append when I switch preferred network from 3G to 2G. At this point everything was fine, but after that, I reboot the phone and then I was unable to registered on network.
I've try many things, I was on running on CyanogenMod 11 Nightlies so I flash CyanogenMod 10.1 stable but it didn't change anything. I've also tried different radio, I was using XXKDH for 2 years so I tried to switch to XXKG2 but it didn't worked.
I've also tried to put the original Samsung Firmware, it didn't worked.
The problem is really coming from the phone because I tried to use my SIM card on another phone and it worked.
I really lost now and I don't know what to do. Is my antenna broke suddenly?
Please help me.
EDIT:
I find that the IMEI showed by *#06# was different from the one behind my battery. So, like few peoples I have the 0049XXXXX IMEI, I'm actually trying to fix my IMEI with this : http://forum.xda-developers.com/galaxy-s2/general/imei-baseband-guide-t1596842 and this http://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 but for the moment nothing is working.
I can't find the .nv_data file so I guess I'm just ****'d but I will try something with .bak files and the efsbackup.tar.gz that was on my SD card for no reason. The most interesting thing I found on the efsbackup.tar.gz is this log file on attachment. Anyone now about what append?
I've also find that my imei folder was empty. Is this normal?
Before I start with the issue, let me begin with some basic information: This is in regards to my Samsung Galaxy S5 SM-G900T (T-mobile), running Lollipop 5.1.1, FOG6 build, DOB1 baseband, rooted, deodexed, but otherwise stock.
My problem: Today I flashed a rom via Mobile Odin Pro and soft-bricked my device. After a lot of hair pulling and screaming at my phone and computer, I finally got my phone up and running again. After trying many different solutions, I eventually tried re-flashing TWRP through Odin (recovery initially would not boot, hence the soft-brick), which succeeded, and then recovered my phone by restoring from a previous backup.
This got my phone up and running again, but once it boot, I had no service. I first checked my APN settings, but was presented with a message stating, "Unable to view the access point name settings. Access is restricted for the current user profile." I tried adding a new APN, but once I added it, it did not appear in the APN list, which continued to only display the above message. I then tried to "Search now" for Network Operators, but nothing was found. So next I checked my IMEI through "About Device", and discovered it was set to "Unknown". Checking the IMEI through the dialer (*#06#) lists the IMEI as "null / null".
I have searched high and low and tried everything I could find to fix this. I tried restoring my TWRP EFS backup to no effect. I also tried flashing the modem through Odin, as well as restoring my TWRP modem backup. I tried using an Xposed app to manually set the IMEI back to its original value (I happen to have my phone's original IMEI number written down from when I SIM unlocked my device), but while this updated the IMEI displayed in the dialer (through *#06#), it did not change the value in "About Device" and did not restore my service.
The last solution I tried (found here: http://www.technobezz.com/restore-galaxy-null-imei-and-fix-not-registered-on-network/) involves me using the dialer to enter Service Mode to make some changes; however, while dialing *#197328640# did open the Service Mode menu, the menu was totally blank.
Please help! Given the current state of my phone, I cannot make or receive calls or texts or do anything else requiring a mobile connection. I have looked everywhere and I don't know what else to try :crying: :crying:
Assistance in this matter would be greatly appreciated, as until I am able to fix this, I don't have a functional phone
Any suggestions?
I managed to install the latest release (non-nightly) successfully using TWRP and performing a format and wipe beforehand. However, upon initialisation, it asks me to connect to the Internet. I attempt to do so, trying to connect to my home wifi network, but even after inputting the correct password, it still doesn't connect. It also claims that there is no signal, when other cellphones in the house clearly indicate 4-5 bars. Somewhat confused, I decide to look into the status of the phone. To my shock, it states that the Mobile network type is unknown, along with the phone number, IMEI, IMEI SV, IP address and network all being unknown. It seems that I am unable to text or call, effectively making my phone useless. I've tried to look around other forums, but to no avail and was wondering if anyone here has had the same problem and potentially has a workaround/solution to it.
Thanks!
You have probably erased your EFS partition... Do you have any whole NAND backup which could contain it?
No backup, I'm afraid, which was real foolish of me. I have no idea what to do. Is there any way to restore it?
It's hard to tell... There are few tutorials out there but with the variety of results... You can try to search for some IMEI restore tutorials.
