Hi. At first, the camera hang when trying to access Main Menu.
Then, after changing lens (i don't know why), i was allowed to go into menu ('passing' via Play image -> Main Menu), and navigate through "firmware update" using the 'wheel' (not button).
So i could re-update firmware to original K-30.
At the moment my K-30 won't work focus and exposure system using normal viewfinder.
Using LiveView works all (exposure meter and also focus system).
Maybe it's broken for other reasons, but i've used with k-30 custom firmware (K-50 for PLM lens) for over 3-4 months without any problem.
