I have unlocked the bootloader, flashed TWRP, rooted on stock Oxygen os. Since, I was unsure about installing custom kernel at the time of doing this, I had setup my apps & stuff.
If I want to install the kernel now, do I have to clean flash Oxygen or can I dirty flash the kernel? I am a bit confused which should I choose Franco's kernel (or should I go with BluSpark) if I want to strike a balance between performance and battery, would appreciate suggestions.
Dirty flashing a custom kernel over stock (rom) kernel is usually no problem. Only if you want to change from a custom kernel to another custom kernel you have to flash the rom (dirty)before flashing the "new" custom kernel. For your kernel choice read comments. (I am using EX Kernel)
