I've been running various custom roms last few days (cloudyg3 2.2 , cyanidel 5.02) rooted. Started with new stock kitkat 4.4.2. Still jumping between roms. Anyway I read a cyanogenmod 12 posting from a couple days ago which said to install the latest modem "v20i". I've searched and search can't find one for the D850. Found one for the D855. Can I use it?
Thanks
