The only question I have is .. I have been running CyanogenMode 11 for a bit but want to go back.. My stock ROM is an MVLUEMK5 for Bell Canada. Now before I went to CM11, I had kernel 4.3.. It now has 4.4.2. Can I still use that ROM ? I know you cannot go back in firmware, but can you in ROM's ? And if I cant, do I need to downgrade my kernel ?
