I have TI-89 Titanium; OS Version 3.10; Hardware Version 4.00
The latest version of PreOS is installed, working well
I can't install CF it has an auto-installer, but it doesn't work with this calculator I need for the .pdk files (example 'cfpack1','cfpack2', exc.) to be unpacked this way I can manually install the files under the folder cf/

If you want to run the installer by hand, send all the pack files while archiving them (it doesn't matter since the titanium has enought archive memory).Then for each pack except the last one (which contains an old version of preos/stdlib) run tinstall("cfpack1") etc.
It should work if my memories are right.
