No Connection After Rom update

---

Hi all,

I need help regarding connection problem of my I9300.

I updated my SGSIII through kies from LE8 to LH1 ( Using Firmware initialization, as Kies was giving message that it cannot update this phone)
But after update i have no network connection at all. There aren't any insert sim warnings anywhere, i just have a circle with a diagonal line through it in the notification bar where the signal bars usually sit.
If i hold the power button to bring up the shut down/flight mode menu,I can turn on flight mode but after getting in flight mode this option is diasabled. And i cannot turn off flight mode from power menu.
I can disable it from settings, but that option also disables and only enables if i exit from that menu and enter again.

I have re installed .LE8 via Odin but it is same.
My phone is unlocked and i can see carrier name in status bar.
Also it does not search any available networks from menu.

Any one knows what is wrong

Are modem and CSC correct for your area .


Have you set up the network manually is the network registered in the APN list .

Have you tried a factory reset after backing up all data ??

But this reads more like a failed flash .

My signals were fine with OXA LE8. I upgarded to LG8.
Now i have reflashed same firmware but it did bot work.


MY APN is automatically configured from sim,
But when i got to network operators --> Search networks, Searching flashes for a second and goes off.
When i choose Network operators --> Select automatically it says registered to network immediately
Also power menu keeps telling that flight mode is ON even if i turn it off from setting. and this option in power menu is also disabled unless i reboot. After switching to Flight mode first time from menu it is disabled.

I did factory reset but it did not help

If it is a failed flash, what should i do?

I have noticed one more thing,

If i remove sim card, I get no sim card symbol. But i get full signal bars on status bar.
In settings--> Status it shows signal strength of 71 dbm 21 asu

Also without sim card the flightmode can be enabled or disabled normally
with flight mode disabled the signal strength is 70-80 dbm, with flight mode enabled signals go to 111 dbm

I have the same error!

Exacly equal on everything you said!

Only diference is, my IMEI was changed by 004999xxxxxx.

And I don't know why!

I've done all facilities to follow many tutorials here, but nothing worked.

I have just noticed that in status menu, serial number is 00000000000.
Is it normal or i have some corruption in EFS folder.

I think you can resolve your issue by restoring efs data

I have checked my efs folder.
following two files are modified at the time when i installed the LH1 firmware.
1- nv_data.bin
2- nv_data.bin,md5

allother files are old.
I think it has some problem. I have .bak files of both files.

How can i restore them.

Do you have EFS backup? If yes, did you try to restore it?
