Next image's are for help you to install the new "image-new.img"(boot.img) on the phone with TWRPrecovery
Atention!
MAKE FIRST A BACKUP before install the ROM and the NEW boot.img
Use only boot.img's for J5xxx/2015 for j5/2015 phones or boot.img's j510xx/2016 for j5/2016 phones
DONT edit/change the RAMDISK files without necesarry knowledge(DONT TOUCH IT!)
USE the SAME android version 5.1.1=>5.1.1 or 6.0.1=>6.0.1 for the boot.img's
DONT report bug's(if you find it) to the DEVELOPPER of the ROM(Will not be take in CONSIDERATION)
You will NOT BRIK te phone IF you RESPECT all the instruction and first 4 LINES from "ATENTION!"(IF you are not shure on your hand DONT DO IT!)
IF the changed file are NOT MATCH you will get a BOOTLOP! so you can try other files from other boot.img
ENJOY by your PREFFERED KERNEL
Thanks!

So, you want to put stok rom 5.1.1 on 6.0.1 botloader!
first you must modify the boot.img replacing the "dtb"(5.1.1) file with the one from stok boot.img(6.0.1)
with ODIN can work or not becouse ODIN chech the version of each file before flashing, but you can try!
after you modify the boot.img, extract the system.img.ext4(5.1.1) file from stok rom.md5
put the new boot.img and the system.img.ext4 in a .tar archive and try to flash it with ODIN
you will have succes or can fail(becouse of ODIN)
also you can use the superRkitchen in linux to compile the rom to be flashed it with TWRP
that "dtb"(6.0.1) file will help you to pass the boot of a 5.1.1 rom on 6.0.1 botloader
that will work becouse i already did it with my ported roms
if you dont know hou to compile the rom with superRkitchen just tell me and i will guide you!

you are blocked in 6.0.1 botloader?
i understand you flashed the rom with success! i'm happy for you!
i beleve that process can be done and vice versa to flash a 6.0.1 rom on a 5.1.1 botloader(i didnt test it yet)
also it can be done with any custom rom BUT becouse we dont have here custom boot.img(6.0.1) except the one from Skies ROM by @BlackMesa123 or of @KingRaheel wich give up the project, the posibilities are limited for now, maybe in the near future
BUT(becouse all the time can be a BUT) can be tryed wiht the "dtb" file from stok rom's on custom rom's
Thanks!

do you have a backup of 5.1.1 stok rom?
if yes, restore the backup and then install the boot.img and reboot
or try the dtb file from King Raheel boot.img (6.0.1) or other custom (6.0.1) boot.img,
i worked with custom files not with stok, that can have some securities in it

Actually my kernel in skies is djsteve one with ramdisk edit for boot note7 rom lol. Btw bro I don't understand the guide.. why replace the kernel binaries when you can just use the boot.img lol

This i did on custom rom, on stok rom can work just to replace all boot.img
on stok rom's the ramdisk can be the same or almost the same and rom can boot
but on custom every rom has his ramdisk wich not work on other
Thanks!
