I think so. No AOSP Rom for Note 3 Neo up to now although its was issued 4 months ago
. I like the design, S-Pen, battery life, price and its performance but I have never seen any hi-end deviced before with no both custom ROM and recovery like it (N750 - hl3gxx).
I think we have to wait or study to build myself
. I have just bought a second-hand Nexus 5 to feel 4.4.3 Rom beside N750.
