HELP PLEASE ! want to upgrade from 4.2.2 to Lollipop



Hey Everyone!!

Thank you for looking at this thread.

In a nutshell, I got my i9505 galaxy s4 since June 2013, rooted it straight away when i got it, its got twrp recovery, and im on omega v9 4.2.2. Havent touched it since to date :P

It does not have knox.

Is there a way I can simply upgrade to something like cm 12.1 with 5.1.1 with everything working, by simply flashing latest cm with gapps using twrp, or will I have to upgrade bootloader, radio, get knox, or even just start over, flash stock lollipop firmware with knox using odin, in order to do so?

I already a while back tried updating twrp to latest, and tried flashing cm with lollipop 5.0 when it first first came out, but only 2g was working, and signal would cut if i lock my phone. Im guessing this is due to bootloader/radio incompatibility? Apparently i cant flash lollipop bootloader and radio over old 4.2.2 stuff without knox?

Any help and advice much appreciated.

Hope to hear soon,

DJ
