As I understand it, after having read every single post in this thread of 34 pages (and growing!), you perform the patch yourself. With the aid of the cable you can download the firmware of your calculator to a computer. Once there, you use a HEX editor to alter the contents of three memory locations. Which ones and to what can be found in post #643.

The question is: How often and on how many calculators do you intend to perform this operation? At least one of the resellers of the HP-15C CE now offers a patching service which costs considerably less than the cable, basically the shipping fees. So if it is only for one calculator it will be cheaper and safer (one can actually brick the calculator with a failed update) to get it done.
