No need to apologize for you English, it's fine.
I'm using Chameleon r2266 from myHack, but I don't have any issue updating to the latest version with Chameleon Wizard either. Before installing, I reset the BIOS to the default, hit apply. Then I go back and set Sata Operations to AHCI, that's it. But you might have to disable Bluetooth if you have one. You could enable it later once you get system up and running, perhaps with a patched bluetooth kext.
You didn't specify the screen resolution, but I'm assuming it's 1366x768. You don't need to patch AppleIntelSNBGraphicsFB unless you want VGA to work. You have the processor as my E6220, so the DSDT/SSDT will be fine for your setup. Try replacing AppleIntelCPUPowerManagement with NullCPUPowerManagement.
Try all the above and see how that goes.
