Troubleshooting for users with and w/o Fusiondrive or incompatible devices that doesn't boot up after patching
First I would not recommend using the patch with a FusionDrive in general. You have a good chance to prolly or most likely end up with a non-bootable second part of your Fusiondrive, because the IOAHCIBlockstorage is responsible for booting it up.
1. For Clover:
Connect the SDD via USB to another Hackintosh or Mac with at least ML or Y, (or boot up into Recovery-USB if you have it), fire up Diskutility with debug-mode ON (google), mount the EFI partition and comment out or delete the patch in the EFI Clover config.plist.
2. For Chameleon:
If you did the patch and modified your IOAHCIFamily.kext, delete it from the kextfolder and replace (or copy) the original kext version from the working Hack/Mac/installation S/L/E with cp -pR
3. For Fusiondrive (Chameleon and Clover)
Connect the first part (SSD) AND the second part (HDD) of your FusionDrive to the working Hackintosh or Mac, and repair the partition table of the Fusiondrive with Diskutility (just select the drive and click the repair button). Additionally, do Step 1. for Clover and FusionDrive or step 2. for Chameleon and FusionDrive.
Note for UEFI users: No matter what, always boot from the UEFI detected devices via your PCs bootmenu.
After that you should be able to boot your system again.
