EDIT: All I need to do is to downgrade my HBoot version to 1.17.xxxx - but I want to find the easiest way to do that.
EDIT2: I unlocked my phone's bootloader. Doesn't help with S-Off though. :/
I will have to wait for Revolutionary to update their tool so that my phone can S-Off (since my phone is 1.27.0000)
May I can downgrade my phone back to Gingerbread, but how? And it looks risky, will that can brick my phone?
I'll press the Thank button if your post is helpful enough.
