NX10 FW upgrade help required.

Hi there,

I am new here, since I bought my NX10 with 30 mm pancake few days ago. The camera has FW 1.05, so I started looking for available upgrades and learned that a number of consecutive upgrades were released, namely: 1.10; 1.15; 1.20; 1.25; 1.30 and 1.31. However only v. 1.15 and 1.30/31 are available for download on samsung.com. I asked samsung how to proceed and if I could upgrade directly from 1.05 to 1.30. They replied: 'No, you should go through all consecutive upgraddes step by step!'. So, I posted a second question-where should I get all those files since only 1.15 and 1.30 are available, but got no reply.

I would like to ask NX10 owners on the forum for help with safe upgrade. Which files are necessary and where to find them on the net.
Best wishes to everybody for the New Year.
