[Q] Unknown network type

Hello !
I have question about GSM status. I own GT-I8190 phone with android 4.1.2 branded by Play Polish GSM operator.
Main problem is all GSM appz not shows network status correctly. None gsm appz works like they should because they are unable to get network type / bts details, even when I enter implemented data - Setting > About device >Status > Mobile network type shows Unknown. Is this known problem or just me ?
update: Flased stock rooted 4.1.2 firmware and still same, can anyone check if apps like 2g/3g status bar detect network type ?

Anyone have got nv_data.bin backup at old security? I read in a forum, mini 2 has got a new security and this methods is not working after. I thinks this is my problem.
First , try and go to settings / wireless and network / Mobile network / Network operators (Phone will search all available networks , it might take 1-2 minutes) / Select the network that your sim has , see if that works , if that doesn't work press select automatically ...Hope it helps.

Restored IMEI now no network issue

Hi XDA,
I have a Galaxy GT-P1000
My locality is New Zealand
Currently flashed;
2.3.6 stock firmware
Baseband JPZ modem
I recently messed up and didn't save efs while flashing and ended up with 0049. I paid a guy to fix it for me and IMEI is showing up correctly now. Serial # is still 000's.
My issue is;
With a correct brand new sim (and others tried) While signal is showing, I have no network, Under Settings -> About Device -> Status;
Phone Number : Unknown
Network : Unknown
Signal strength : (good)
Mob Network Type : HSDPA
Service State : Out of service
Roaming : Not Roaming
Mobile Network State : Disconnected
IMEI : (correct)
Serial number : 000's
I cannot make any phone calls, even toll free or to network support. 5 days ago this tablet was working on a network before flashing it.
Any help would be greatly appreciated. Thank you
You could try re-flashing the tab. There is a threads on re-stocking gsm tabs back to stock. If that doesn't work you could try manually programming the tab via the memo app. Open memo > in the search box type **772, that should open the programming menu. Thats as much as i know. You have to take it from here.
