HP 15c Collector's Edition save/restore does not work

[Divasson]

Hi,

It works for me.

While the calculator is off, press [f]+[ENTER], hold them pressed, and then press and release [on] (nothing happens yet), THEN release [f]+[ENTER] and the calculator switches on in HID mode.

The back-up file has always 2048 bytes - no matter the memory size mode we're in.

If you do not get a permanent HID link then we have a problem...I'd reload the firmware and check that it is the same using the SAM-BA check button.
