I think your first try could be to restore the stock rom with odin.
Also, there are some hits on restoring imei when you google.

Goodluck.

It's normal, i suppose you've flashed epsilrom.
Next time, you'll read the title of the op, this rom is for 850f not 850s
Now you need to reflash 850s stock rom via odin

Yes your right
Because if it was the snapdragon variant, the rom will be not able to boot.

I'm not sure, and would like if somebody could correct me if wrong;
If you backup your modem from stock rom before flashing the ROM.
Then after installation of the rom you could restore your modem and it might work, but no guarrantees.

I have same problem. but instead of null , it shows 004999010640000 / 73. Stock rom didn't helped. I have tried to flash via kies too. but no luck ? Anyone have any idea ?

Those information are normally stored in a location that won't be overwritten by factory ROMs. If you flashed the wrong ROM and destroyed the private data for your phone (IMEI), good luck to you. No amount of factory ROM flashing will correct it for you.
