Install 3.55 CFW. Then upgrade directly to 4.80.1 Rebug or another CFW like HABIB or Rogero 4.80 CFW. Once installed, take out the HDD that is currently in there. Install your 4.65 HDD. Access the recovery menu, holding the power button so it turns on, keep holding it so it turns the machine off. Turn it back on holding the power button, so it beeps once, then keep holding it until you hear a double beep. It will now be in the recovery menu. Plug in a USB disk with the PS3 CFW you used to install in this folder on your USB: PS3/UPDATE/PS3UPDAT.PUP.
Click on system update, it will find 4.80 CFW on your USB. Install it, then you'll be back on 4.80 CFW with the other HDD you want.
