W910i lost camera after flashing

[aspirin]

Hi everyone,

I had w910i with vodafone firmware, I dowloaded the R1FA037_RED52
fbn and mbn files and did the procedure according to instruction in:

A2-DB3150 Flashing - Top Sony Forums

After flashing, when I press the button for the camera, display shows the
startup screen for the camera for a few seconds and then it goes back to
the wallpaper, no errors or anything like that happens, but the camera does
not start.

The phone was branded to VIP network (vodafone network in Croatia) if
that matters.

Is this a firmware issue or is it something else??
Anyone with any information about this, please help!!

Thanks in advance!

Update:

surprisingly, it wasn't the firmware that is the problem, it was the
flash theme I've put on the phone.... How is that possible? When I
put a regular (non flash) theme, the camera works fine?!?!?!
