From previous experiences it is most likely that you will need to create a Pandora battery to install the firmware.
If you have an OFW (3.71) then the security on the firmware either needs to be broken or bypassed. As there is no known exploit of 3.60 or 3.71 OFWs it leaves the Pandora battery option to bypass the firmware altogether.
It is probably for the best to start organizing yourself and working out how and where to get a Pandora battery and memory stick in advance if you want a CFW on your slim.
