The problem may be the fact that you have a i747 with an i747m bootloader.

Did you intentionally load the i747m bootloader onto your phone?

i think i am using old i747m bootloader. lemme flash i747 bootloader and see how it goes.

I believe the mk5 bootloader is the newest one for the i747m.

Be careful as cross flashing may cause your phone to brick.

i am using old i747 i747ucdlk3 bootloader and i747mvluemk5 rom. wifi won't work.

i am using old i747 i747ucdlk3 bootloader and i747mvluemk5 rom. wifi won't work.

Does the ROM you are using have a mk5 (i747m) kernel or modem installed with it?
You probably need a i747 kernel and modem for wifi and data to work correctly.
