How do I jump from 5.1 (Lollipop) to 7.1 (Nougat)?

My g4's still on lollipop. Today i've finally unlocked the bootloader and installed TWRP and now I want to switch the stock rom with something custom.
I have downloaded the latest RR rom which is 7.1.2 r17 and it is the ROM of my liking.
Do I just go ahead and flash this? I guess not...
I could not find an explanation.
I think I need a matching modem and bootloader, but I could not find that info anywhere.
Can someone please help me with the procedure?
I would appreciate a few hints on how to make this jump.
Thank you.

Samsung Galaxy S4 mini i9195 NEED flashing tools, rom and some advice

Hi
I have a Samsung Galaxy S4 mini i9195 and i'm curious is it possible to flash a phone without battery over Flash Tool ?
I am using MediaTek SP Flash Tool v.5.1728.00 and i was flashed my other phone Huawei Y360-U61 without battery, but i can't find any stock ROM for gt-i9195.
Any advice will be good.
Thanks in advance.

S4 mini does not have media tek chipset so that tool will not work. You need Odin or Kies (for Widows PC'S).
Edit: you can get a stock ROM from

You need odin and corresponing rom. I found newest through search with google. I have an european model and could upload it for you to my gdrive account. Its Android 4.4.4 from Debitel (Unbranded). Alernativly you could install lineage os 14.1 from arco68. Its newest android 7.1.2 updated weekly. Works very well.

I have seen you are from croatia, so ideally you find a rom thats for croatia. On sammobile you find just 4.4.2. I have a french (reimport) GT-I9195 and after flashing of german (because of releasing roms much earlier in germany) I was able to change but not anymore back to french. Don't know why, but I can live with them. After flashing I have to go to samsung recovery and Iam not sure what I have exactly done. I have since 8 months lineage os. I think it was enough to go to recovery mode and in log you see thats the recovery mode changes some parameters and the phone works again. Before wlan does not worked for me. Alternativly you could try -> Delete cache -> Factory Reset. But Iam sure this was not necessary.
