I already install Clockwork-Mod Recovery (CWM) v5 and i used that upd_1.zip for root my galaxy ace but it didn't, any one knows how do that thing.
Did a quick google search and think this can help you: http://androidadvices.com/root-samsung-galaxy-ace-gt-s5830-gingerbread-firmware/
I Recomend reading the whole but if you want to skip to the rooting just jump to part 3: http://androidadvices.com/root-samsung-galaxy-ace-gt-s5830-gingerbread-firmware/3/.
Many roms have root set in rom properties this will also root your device, which meens that the rom will actually root for you.
