hello
i recently bought a new s4 i9500 international and im a bit confused.
When i boot into odin/download mode it states the device model as i337 (att variant of the s4) but this is supposed to be a gt-i9500.
it is currently on 4.3 jellybean i want to upgrade it to 4.4.2. or lollipop how do i go about doing that.
I want to send it to Africa which firmware do you recommend.

You own a Frankestein. Install this APP and add some screenshots.

@androidfine16: Without seeing your information from Phone Info, I can virtually guarantee that your only means of upgrading will be to install AT&T firmware, which will not lead to a good experience unless you're not planning on rooting the phone. AT&T locks its bootloader, making rooting virtually impossible.

If you just got this device, run, don't walk to where you got it from and return it.
