I haven't upgraded to 1.6 yet, but I intend to now that resetting the KPA seems to fix the problem addressed here.
Question, should I delete 1.54 from my memory stick before downloading 1.6? Should I wipe the memory stick clean by initializing the memory stick? Also, what am I going to loose when I reset the KPA after loading 1.6?
As always, thanks for your help.
No need to wipe the memory stick, just replace the 1.54 file with 1.60, the KPA won't upgrade if it finds 2 firmware files in the memory stick. I'd recommend performing a backup beforehand just in case.
