3.41 OFW> 3.15 OFW require modified 3.15?

I looked all over google and this board but I couldn't find anything. I have a feeling you could just use the official 3.15 and Jaicrab's Lv2diag to do this but I want to make sure so I don't risk bricking. Please correct me if I'm wrong!

Ok I bit the bullet and downgraded anyway. I went from 3.41 OFW>3.50 OFW>3.41 modified>3.15 OFW. I went to 3.50 OFW because I needed to get to the 3.41 modified because I found what Chesh said:

Then I downgraded to 3.15 OFW with Jaicrab's Lv2diag but unfortunately this didn't restore my dongle jailbreak ability. Oh well, I'll probably update to 3.55 CFW. Hope this helps.
