Samsung GT-S5233 Star firmware help...?

[Davin]

Hi. I have recently changed and installed new firmware for my Samsung Star (This one: http://darkforestgroup.com/forum/index.php?topic=4985.0). But a few days back I scratched my phone's screen against a wall and damaged it badly. I want to take in my phone for repairs but I don't know if the warranty will be void because of the changes. I want to convert my firmware back to my old one's and hope they don't notice I've changed my firmware a few times. Does anyone know where I can get the original Samsung GT-S5233 Star firmware???? Please help.
