Required Img files for heimdall root

Folks, I'm trying to root a phone with Heimdall (on Linux). Completed steps so far: 1. Downloaded Factory Firmware 2. patched it with Magisk 3. setup heimdall 4. downloaded PIT from phone 5. backed up phone with

backup -apk -shared -all -f /backup.ab

6. installed twrp recovery So now I would go on and flash the patched images. From the magisk patch and the firmware, i get those files:

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

Comparing this with the contents of my PIT, I am missing these files:

md5.img
efs.img
cpefs.img
m9kefs1.bin
m9kefs2.bin
m9kefs3.bin
carrier.img
tombstones.img
dnt.ssw
steady.bin
modem_debug.bin
nad_refer.bin

Some people only use recovery.img and cache.img, others use all of them, so now I'm confused. Hence my questions: - What is the minimum set of files required to flash in order to root the phone? - I.e. are the ones I have enough, respectively - are the missing ones required? Thank you big time!
