Can't get into Clockworkmod recovery on LG Optimus 2x

I flashed a MoDaCo ROM this afternoon just to try it on my LG Optimus 2x P990, which was on ICS (CM9). I see that it's based on the offical LG Optimus 2x ROM, but I decided to flash it back to Android 4.0.4 ICS again, the one I was coming from. But I can't get into ClockworkMod Recovery. I didn't find ROM Manager on my phone after flash (it works, except for Market and has **very** many bugs), so I reinstalled it by sending the *.apk to my email. I installed CWM successfully, but I can't get into it. I have tried the volume and power button method and reboot from ROM Manager. None of them worked. My phone does works (call and such), but I can't get into CWM, which is **really** annoying.
