Samsung J5 2017 (aka j5y17lte) installing STOCK ROM

After installing a custom ROM (s. here) i wanted to flash the STOCK  ROM onto my smartphone again.

So what to do?

First: Download a ROM (e.g. sammobile.com)

and you will get something like

J530FXXU6CSK9_J530FDBT6CSL1_DBT.zip

this zip cannot be sideloaded. So you have to unzip and the you have:

AP_J530FXXU6CSK9_CL16642474_QB27583084_REV00_user_low_ship_meta_OS9.tar.md5
BL_J530FXXU6CSK9_CL16642474_QB27583084_REV00_user_low_ship.tar.md5
CP_J530FXXU6CSK9_CP14486297_CL16642474_QB27583084_REV00_user_low_ship.tar.md5
CSC_DBT_J530FDBT6CSL1_CL17419960_QB27658856_REV00_user_low_ship.tar.md5
HOME_CSC_DBT_J530FDBT6CSL1_CL17419960_QB27658856_REV00_user_low_ship.tar.md5

Within this you have to do a:

 for a in *md5; do echo $a;  tar -xvf $a; done

and the result should be:

boot.img   cm.bin      modem.bin  recovery.img  system.img
cache.img  hidden.img  param.bin  sboot.bin     userdata.img

(then you can follow this guide: https://ar.al/2018/07/15/flashing-stock-firmware-onto-a-samsung-galaxy-s9+-sm-g965f-on-ubuntu-18.04-using-heimdall/)

or just type:

~/bin/heimdall flash --BOOT boot.img --SYSTEM system.img --CACHE cache.img --HIDDEN hidden.img --PARAM param.bin --CM cm.bin --USERDATA userdata.img --RADIO modem.bin --BOOTLOADER sboot.bin --RECOVERY recovery.img

and after nearly 10 minutes of anxious waiting you J5 boots up with the STOCK ROM again.
