Help, my K810i got CID53 !!!

[sergage]

Ok, can somebody please tell me how to flash main and fs firmware with jdflasher? I have the latest versions of far manager and jdflasher that support CID 53. All tuts I can find on the web are about patching, but I don't need to patch, I just wanna flash. I have RED52 firmware, can I still patch a CID53 phone with it? Also jdflasher only offers ofs and oflash, there are no bflash or bfs options. If anybody knows how to do this I'll be very grateful :) .

EDIT:
No matter what I try to do with jdflasher on my own, I get a SetDirectory error.
