[Q] Updating to a newer ROM version
I am currently on 4.1.2 12.0.A.2.254, rooted eXistenZ Ultra 3.X (LB).
If I am to upgrade to the newest eXistenZ Ultra 4, would I first need to update my stock firmware to 12.1.A.1.205, re-root, apply latest Doomkernel etc. and then flash the ROM or does the ROM already contain the newest firmware and kernel?
I know the set of instructions are on the second post
, however, I just wanted to verify if this method is outdated for the newest ROM update.
