Firmware help please

PD1117 · 08-18-2014, 11:52 PM

Thank you in advance for any help you can offer. I have an old K100D that is still running v1.0 firmware. Following the theft of the DSLR that I've been using for the last few years I want to go back to the K100D for a while. To be able to use a decent capacity SDHC card I need to update the firmware. I've downloaded the latest version v.1.02 and followed the instructions, copying file to an 8GB card etc. However I seem to be stuck in a loop - the firmware needs at least an 8gb card to update the camera but the only 8gb cards are SDHC, and my old Pentax won't read SDHC cards until I install the latest firmware. I'm obviously missing something here, can anyone point me in the right direction. Thank you.

The card needs to be at least 8Mb, not 8Gb. I read somewhere that if you format the card to a partition under 2Gb, the camera should recognize it anyway.

Otherwise, just get a normal SD 2Gb or smaller and you should be good to go.

Thank you Adam - what a rookie error! We're so used to high capacity memory these days that I no longer think in terms of Mb, and clearly my brain reads Gb by default! All worked perfectly & upgraded thanks to your help.
