May you have deleleted the Baseband? Baseband is not included in the ROM's.
Try to install the Baseband separately via recovery.

You have to do flash these things before you flash a custom ROM. Go back to stock ROM and restore your backed up folders to avoid a corrupt modemfs or efs folder or maybe a soft brick.
Note : be careful if you do something with your EFS folder. You need this folder for calling, receive SMS, internet, WiFi, Bluetooth, IMEI and serial number.

No IMEI no backup.

Hi everyone,
I recently got a i9000 that was on icm via devils kernel. I did a factory reset on the device and think this corrupted the EFS folder as i was given the generic IMEI and had no signal. I flashed back to a stock GB 2.3.5 and managed to get my own IMEI back on the phone. I still however have no signal so wondered what to do next?
Thanks

it's very very easy dear friend.
just root your rom, install latest root explorer ( i search on google for u, here u can get it) and then u can back up efs folder easy on (by) it .

You won't get your IMEI back by flashing a 3-part-Rom.
What problem with your IMEI do you have? Starting with 004999...?

As I said in the other thread. I don't have stock so I can't giude you.
Look around in the menus, and use the meny key to go back in the service mode.
You will find it. nv rebuild.
---------- Post added at 08:06 PM ---------- Previous post was at 07:55 PM ----------
When your nv is rebuild, reboot twice and see if baseband is shown.
Otherwise flash stock rom again, now that nv is rebuild.

Sometimes work, and sometimes not?
If you got backups from cwm or twrp of your /efs and /modem, please restore them.
Never wipe efs or modem when flashing a rom.

Ok. Flash a stock rom where everything works.
You can try this one: I8190 серв. укр.rar
It's the most complete rom iv'e seen for i8190. If everything works and you want to flash aokp or cm, just make a factory reset.

Ok, good
Make a backup of your rom. You can also make backups of your apps with titanium backup or similar for easy restoring of your apps.
Flash aokp or whatever you want + gapps, make a factory reset and reboot.
See if that works.

So, what else did you already try ? Flash different version of modem ? Reflash stock ROM via custom recovery ?
Baseband version shows Unknown. Try reflashing your modem.

Download your modem flashable zip here https://www.dropbox.com/sh/d2ljv1ylvr9nvib/M7UzMgux4f and flash it again. If no luck try with a different custom recovery. CWM or Philz for instance.

yes flashed modem again with cwm rom, booted into recovery tried to flash modem I9305T_DVBLL3.zip.
should I try a different modem ? my phone model is I9305 not I9305T, maybe this is why its not working ??
I have the same situation when went back to 4.3 rom from 4.4 rockyard. Nothing helped. So I restored backup of 4.4... and everything works. I'm currently using this Rom without problems (old rockyard ported from Note).

Is it the mediatek version? If so, install Ghost Phone from Playstore and write down the IMEIs there. At least that app generally works with any mediatek out there (you need root).
