[Q] convert SGH-i337 (AT&T) to GT-i9500 (octa) ?! see more here topic

hi
i just bought an galaxy s4 gt-i9500 from a freind (thats what i guess ) but surprised for what i found out
you can see screenshots attached below
my i9500 has :
Chipset : Qualcomm APQ8064T Snapdragon 600
CPU : Quad-core 1.9 GHz Krait 300
GPU :Adreno 320
and also 4G network support
and in bootlogo there's no i9500 apprear just samsung galaxy S4
so i am confused what is this S4 ? :confused:
answer is:
this is not i9500 octa-core but its SGH-i337 for AT&T with firmware of i9500
AP :i9500XXUEMJ9
CP :i9500XXUEMJ9
CSC:i9500XXUEMJ9
BUT with SGH-I337 bootloader as u see in screenshots
so big question is can i flash this phone with sgh-i337 factory rom or no and dont forget an important thing the Serial number label (sticker ) inside the device with i9500 Written in it :rolleyes:
