A90

A- I have a Pentax Opio S hence I had to get the "fwdc110p.bin" file here:

http://www.badongo.com/file/707791

B- Drop this file on your SD Card at the root directory (same level as DCIM folder) or as described by the following link and then close your camera to OFF:

Attention: Do not load this file yet onto the camera i.e. the menu+power on procedure, follow step C first...

Important!!! Insert a fully charged battery or connect to an external power source.

C- Open the now infamous "Secret Menu" in order to re-initialize your camera prior to re-installing the new firm ware: Simultaneously press MENU + Flash symbol button + Power ON...a white screen with data written in black should show.

Then a sequence of buttons must be pressed: 2 times the focus button (flower, mountain, MF symbols button) followed by 2 toggles to the Right of the "OK" button...then press MENU once and voile...the Secret Menu appears!

Using the down toggle of the OK button, go to ROM UPDATE then go down to "SYSTEM INITIAL" and press OK. Press another OK to re-initialize your camera.

Once this has been completed, turn your camera off.

D- Load the firm ware by opening your camera with the MENU+Power ON procedure...finally this should be posting "Complete" after the "Loading" message, instead of the "Error!" that we initially kept on having.

Your camera should be working perfectly! Only thing is that you will have to redo your personal settings on it from scratch...but hey, this is much better than to wait for months to get your camera back from Pentax and save that money for your next photogenic trip!
