Sorry for reply time, but forums e-mail notification mechanism is not working for me, so I did not notice that someone replied to my thread.

That was "SM-G920F_12-5-2017_16-55-0__RF8G30J9HTD_nv_data . rar". For some reason I am not allowed to post links and attaching files to message (it always ends with upload fail error), so I am posting link below to my Google Drive, with spaces around dots, so You need to remove two spaces...
