That's right. Find the vendor.xml file and delete it.
Should work after that. You can also use the modified .ALX file if you want to have the unlocked themes added.
I recommend installing the OS with the standard .alx file then after all goes well, replace the blackberry.als file with Jibi's then running desktop manager again. A few have had problems when using the modified .alx file during initial install.
