so, i guess the first flashed was screwed.. so i shut off the phone, re-enter download mode, then start the flashing process again. but at the end, also same, force closed and cant see home screen.
Did you follow the method correctly ? Did you take out ur memory card and sim card when flashing ? (but take ur SDcard/SimCard might not be necessary)

so, i decided to revert back to our region latest firmware, the KC1. re-enter download mode and reflash.. IT BECOME WORST! at the end of the flashing process, Odin says "wait untill rebooting" but the phone did not reboot, but the screen just turn black!!

.. tried to removed battery, but the phone just remain black.. when i plug in to PC, Odin still can detect it tho.. what should i do??
You shouldn't tried downgrading and flash from KPH to KC1...
Try this , (might not work for some ppl)
CODE
If your phone doesn’t boot into download mode and you have a black screen after flashing froyo heres how you unbrick it.
Step 1 – Prepare odin with the firmware u want to flash (in my case was gingerbread 2.3.3) and get it ready to go;
Step 2 – Remove battery, SIM and SD card, next connect your galaxy ace to the computer;
Step 3 – Hold Volume down + Power + Home button at the same time;
Step 4 – Insert the battery and wait a bit;
Step 5 – At this point Odin should have detected your SG Ace ( Yellow rectangle should appear);
Step 6 – Click Start button in Odin and wait about 5 min.
If all goes well it should come back to life.
