Update Anroid kitkat 4.4.3 for S4 GT-I9500

[savuth]

I found a daily alert that the Samsung Galaxy S4 GT-I9500 can be updated from 4.4.2 to 4.4.3. After I follow the instruction, it so complicate for me to update this firmware. That is why, I drop this A&Q to the forum.

If anyone in this forum have experience to update this firmware, please kindly share with me.

Thanks
