[Q] Galaxy Grand Duos IMEI lost - General Questions and Answers

I have a Galaxy Grand Duos which now has an IMEI 000000000000 after upgrading to 4.2.2.
My question is how can I restore the IMEI ?
1- If i downgraded back to 4.1.2, does it work? If yes how is it done ?
2-If i rooted it and installed a custom ROM, does it work?
3-If none of the above, please tell me how to get the IMEI back ?
Thanks in advance for whoever tries to help.

Hey,
Yeah you can flash the stock firmware for the Galaxy S4 via ODIN without any problems.
It will restore your ROM to stock 5.0 touchwizz.
Cheers.
but it saying on online forums should be the samsung S4 with same model Number
It saying on online forums it should be exact samsung s4 with its own model number ? No problems?
You need to flash stock s4 firmware
