Originally posted by csa I'm having problems; I'm not computer savy. The file downloaded in a 7-Zip file manager:
wdc 220b.bin
I cannot open it, as per instructions show the two files.
I'm really afraid I might mess up my new K3, not knowing what I'm doing with this update!
The self extracting zip file is k3_v121.zip, so If the file you have is Fwdc220b.bin it seems to me that you already have the extracted bin file.
Unless others can naysay this I would reckon you could put this (the .bin file) on an SD card and see if the camera recognises it as a legitimate update.
Please ensure that your battery is fully charged before trying to update, and don't go ahead if you are in doubt.
Cheers,
