Editing E-M5ii hires files

If I want to redit the raw, which ones of these work:
1. Use lightroom using the trick which substitute the E-M5ii camera type for E-M5
2. Use adobe DNG converter and then edit in lightroom
or do I have to make a TIFF using Olympus' own software and just edit that ?

thanks in advance

 

thanks, 2 actually works ? I will try it
And does the DNG convertor work with the raw ORF as it comes out of the camera ?

 

Posted a hi-res image here:

quite like the hi-res mode. I tried HDR as well but like the hi-res more. It seems that hi-res does increase the DR abit.
The water was a mess as it was moving, but the buildings were fine and the sky was also fine as the clouds were moving slow enough not to effect the picture.
This was jpg only. Need to work out how to get raw file.
