I updated both lenses just after I'd finished updating the Q body. All went well and was over and done with in no time.
All I need now is some fine weather to try out these updates. Might have a wee wait though!

Result!

Thanks Barrie. Went through all of your ideas and it seems to have been the SD card! Try'd the update using an old 512meg card....worked first time!

New SD card will be in the post back to Amazon tomorrow

Once again THANKS

Also thanks to Bernard for his help.

Batteries are fully charged and perform well otherwise so don't think they're the problem.

Hi,
Having a problem updating my Pentax Q firmware. I have the update, fwdc208b.bin, on a new SD card ready for the install but every time I tell the camera to update it just says ''LOW BATTERY''. Battery is Pentax and 3 weeks old, came with camera. I have also bought a second battery but camera still says ''LOW BATTERY''. I have had a wee look online for the mains power option, K-AC115, but no luck!!
Any ideas folks?
Thanks
Graham
