When I updated my 50g to 2.15 some months ago, I tried the above

Realizing I was probably shortening my life expectancy and that of the
keys on the calculator, I used the SD card method and then found myself
wondering why I hadn't gone that route before reaching such a high level
of frustration.

This was linked to from their main driver and software listing for the calculator (ie, not through 40 layers of caution this is a beta don't use this or you may die of seemingly unrelated causes because we didn't test the killowner function thoroughly yet).
