At the point just after you double click on ofs I found when flashing my w580I RED CID53 that I had to get to the folder that has as its contents doja drm as shown in the demo then I copied the contents of the custom folder there ... It wasn't obvious to me that you had to do that and the first time I tried I just double clicked on the .. and then copied the custom folder to there but that gave me an error when I put the simcard in "Configuration error contact your network supplier etc." I found that the phone worked fine when I copied the custom folder to the correct place !
