Since the last firmware release for the K-30 (V1.03) was buggy (for instance, quite some K-30 users reported that the machine hanged up from time to time), Pentax has released a new firmware version to correct the errors:-

I hope this time it will work.
On the other hand, the new Q firmware of the V1.11 was withdrawn just within one day
