Hi,
I have installed Omega v56 numerous times now (even gone to the point of unrooting, getting rid of recovery and a stock ROM then flashing all of them back) and I still have no internet (mobile data). On the stock ROM I had mobile data (it was also android 4.3) and I had mobile data. I flashed omega and no joy. I have flashed all three modems in the omega files section but none provide me with mobile data. Any ideas?
Many thanks,
Jon

CHECK APN settings with your network first .

trying to get the backup of one phone (4.3) onto another (4.0.4). when backup is restored to the second phone the wifi scans but wont connect (auth error). sim card not registering either. on the board it looks like the same model of i9300 as well the dates on the board of manufacture. one is from dubai and one from bulgaria. wondering if this is fixable by flashing another radio or is there more to it than that? when restoring to the original (4.0.4)it does get signal.
I think the problem is because of identical MAC address when you restored from another cwm backup.
try google and search for how to backup mac address and restore that file after resoring from cwm...

thanks for the idea but it cant be the mac address since i was able to connect to everything just fine when i restored to my old backup. Also installed a new version of 4.3 (android revolution hd) which connects fine to everything. I was just hoping to avoid reinstalling everything when i have a perfectly good backup from another seemingly identical I9300.
It appears the imei has changed. but why? how? after restoring now it will not connect to any sim network now. but wifi is fine. all i can think of is flashing more modem files and see if that helps?

thanks for the links. problem solved by a visit to samsung. nice fellas fixed at no charge while i waited.
Today I got my phone back from service, they have fixed my IMEI, and everything was working fine, I've also backed up my efs at the beginning. But I wanted to mess a bit again with my fav roms and kernels. After flashing both of them, my Imei was fine, I still have signal bars, but I have an errors: "Only emegrency calls", and "not registered on network". I've tried to flash stock 4.3 again, with no results. Any suggestions?

You mean this:
http://forum.xda-developers.com/showpost.php?p=45038238&postcount=466
It works, but only with stock rom (fully stock, not custom ones stock), and it's null/null at the beggining, but after some secs it goes right.
With other custom stock roms I have null/null with it.
With normal ones I have right imei, right sn, but only emegrency.
Restoring efs doesn't do anything.
CM 11 works fine with modded modem.
Zuluman's modem patcher v2 is also giving the same results. Tried with MK6 modem.

Hi,
My S3's baseband is XXELL4. Recently I have tried Echoe Rom (4.3), which had a note that it wont alter modems, and if I lose network, I should flash MG4 modem to restore network. But after flashing, my IMEI was intact and I was able to get signals but when try to make calls, it shows "Not registered on network" error. Tried restoring my backup but again the same error for my previously working backups.
Since all the workarounds mentioned here did not workout for me (Including flashing stock 4.1.2 XXELL4 firmware and EFS restoration), I did a master wipe, restored XXELL4 modem first, then restored my EFS backup and flashed Fusion 4.4. Now everything was back to normal again.
So my question is how do I convert my EFS v1 modem to EFS v2 without losing network communications. I am interested to try modified stock 4.3 ROMs, as my primary requirements are fluidity with more juice for the day. So I need to flash a 4.3 stock based ROM and how do I do it without facing the same issue agian.
Any help from experts will be very much appreciated.

Thanks for the help. So if I flash this patched modem over XXELL4, will my network will still be working. Sorry for too many questions since my requirement would be hassle free switching between ROMs without losing network communications
Hey guys, few months ago I got the not registered on network issue after flashing 4.2.2 firmware
I think it changed the efs to v2 and is not compatible with italian modem firmwares.
so I tried:
- ariza patch, kernel and custom baseband modem
- odin flash with some old and new firmware
- kies initialize
- downgrade to 4.1.2 and update via kies
- flash modems
now...is out there a fu%&£*g genius that has another suggestion? lol
my imei is ok
Efs corruption is the usual cause of network connection issues, unless you have a backup then you will need an expert repair -to wipe the efs, flash a blank then code your imei and serial number back in.

i actually had this just today too. read somewhere in google the following, and it worked for me.
flash an aroma rom (i chose stock archi), tick the flash modem option in the custom install settings.
once flashed i got my data and carrier back. hope that works for you too
Hi,
I am using the I9300GSMH mobile. After flashing the CM11 to my phone, I lost the mobile network connection (2G and 3G). I know the problem was due to lost of IMEI (I got the blank info after type *#21#). I am trying to flashing the stock ROM using ODIN right now. But what can I do if I really wanna to use the CM11 for my mobile?
Many thanks!!
Jerald
Problems with imei stem from your efs folder, restore the efs backup you made before you started flashing anything.
