[Q] D800 to D802 conversion topic

Hi all

I have a AT&T LG G2 running stock Kitkat with no modifications.

I compared details specifications for D800 and D802 and found that even the cellular modem chip is same.

Is there any possibility that D802 firmware could be flashed on a D800 with full compatibility? Even if it involves some modification to the firmware files.

Please provide any inputs on this.

Thanks
Adi
