Downgrade/Revert firmware of Pentax K-x

I think I have problem with firmware v1.02. Since I upgrade to v1.02, my monitor problem cannot display. But then sometimes can. I've sent it to service centre to fix and replace the monitor, but the problem still arises. So I guess my desperate step is to downgrade to firmware v1.01.

Can any sifu guide me how to do this? I don't want to send to service centre as it's not convenient for me.

See the similar threads below for more details on the actual downgrade.

What's the exact issue you're facing? Chances are that it's not firmware-related.

From what I get I assume I just need to reinstall normally v1.01 over existing v1.02?

The problem happens a day after I upgrade firmware to v1.02. My monitor screen turned off after I used the K-x to snap photos for a while. Then after some rest, it turned on again, but sometimes after a long rest, it still doesn't turned on. It's a random thing I cannot see any patterns. The other thing works just fine, just the monitor can't be turned on no matter what buttons I pressed.

I've actually replaced the whole monitor at service centre, but the problem still there. Of course I would like to return it to service centre, but it's far from my place and very inconvenient.

That issue is probably not related to firmware. If your mode dial is broken, you'll have to get it serviced.

Maybe try resetting your camera? Might be some sort of conflict!
