Help How do I get my GS2 back to factory firmware

[Sapper Bomb]

Hi, I bought a Galaxy S2 in september last year thru Bell and I rooted it and put XXKI3 ROM on it. I am having issues with the battery and need to send it back for repairs. Before i do that i need to get it back to stock so as not to void my warranty. If anyone could tell me how to do this or even point me in the right direction I would greatly appreciate the help. thanx
