Hi all from a newbee.
Just got a new K5 from Jessops with firmware 1.01. Did a shoot out on a night out on Friday and no issues (except maybe focussing). Thought I'd update the firmware especially after reading the low light focusing issue comments.
Latest looks to be v1.11 which I got from http://www.pentax.jp/english/support/digital/k-5_s.html

I had a fully charged battery and followed the instructions. On the rear display I saw UPDATING and phase 1/2 and then phase 2/2, before seeing COMPLETED with the red light flashing.

I switched off, removed the SD card with the update and switched back on.....nothing...no power at all

I have left the battery out for 5 minutes and replaced and still nothing. Tried with and without the SD card, and with and without the firmware file on the card. With and without holding MENU - and all combinations of the above...

Camera is dead.

I cant find on google any similar problems. Any views/comments/actions to take?

Thanks

Bob
