If you have old twrp backup of any rom which is earlier(in yout mobile not other mobile only your mobile don't try backup of other mobile if the mobile is same then also not try only your mobile backup) then to goto twrp hit restore and restore efs only
Or try to reflash ypur rom using this method
Use this method
1- swithoff your galaxy grand 2
2- power on to download mode( volumedown+download+power)
3- open Odin choose tar file(stock framware)
4-(most important) unmark auto Reboot, mark F. Reset time & Nand Erase All & phone bootloader update & phone EFS clear. see attached image
5-connect your grand 2 to your pc it will be shown in odin like com?
6-start odin to flash firmware to your grand 2
7-when odin finish don't reboot just remove battery for 20 sec.
8- re-insert battery and power on in recovery mode( volume up+home+power)
9-leave it do its work till samsung logo appears on screen remove battery again.
10- re-insert battery power on to recovery mode.
11 - in recovery do factory restore twice then reboot.
You can download the firamware from samobile google it and search for girmware of your model number with country code of country

Or open trminal emulator and type
Su
Grand permission
echo ‘AT+EGMR=1,10,”IMEI_NUMBER”‘ >/dev/pttycmd1
And reboot
In place of imei number enter your imei number
Found backside of your mobile where battery is placed
Or box of your mobile and its bill
And again do at your own risk. I am not responsible for any liability occur or any thing happen with your mobile
As you using this method your and only responsible for it not anyone else...
This trick only work on Chinese MTK mobile..
