difference between both "Dyneteve" build have fixed flash & focus issue, but only for LL boot loader1. For J500H, what's the difference between this and Vince's Lineage 14.1 ROM?
2. I'm in marshmallow, Do I have to downgrade to Lollipop before flashing this ROM?
3. RR vs Lineage which is better?
if you on MM boot loader, you have need to downgrade LL boot loader before flashing this ROM
RR have extra & fulfill feature, on other hand Lineage OS have their standard & limited feature,
Note: still Vince (14.1) build not fixed some issue like (Rear Cam flash & focus,OTG bug), you can flash vince build with both boot loader (LL & MM)
