[Q] please Help with eXistenZ rom and .307

Hey! First thing first.. I´m a noobie. :silly:
When that is said I have a XZ locked bootlodaer, rooted, .253 firmware. I have model nr C6602 now, I had C6603 on .434 before .253 flash. ****ed up a littlebit.. :cyclops:
Anyway I want to install Niaboc´s eXistenZ and upgrade to .307 If that is possible ?
My question is : Do i have to downgrade firmware to .434 and root all over again - then Uncheck kernel, fota, data, cache & appslog on .253 and hit flash button? And AFTER that I´ll Install eXistenZ Black v3.zip from recovery? or other way around ?
If that is the case is it possible to upgrade to .307 after all this ?
I tried to install eXistenZ Black v3.zip from TWRP after I did the .253 flash.
That did not work , the android dude went down on the ground with a yellow triangle sign on the stomach.
If anyone can give me a step by step noob guide to achieve this (A little more describing than OP) then I'd be eternally grateful! :fingers-crossed:
Thanks in advance, and sorry for my stupidness, I've just started with android, thanks to XZ!
And if these questions has been answered already I´m truly sorry, Then I'm really bad in forum searching too.. please give me a link :highfive:
