NOTE: STOCK RECOVERY OF GALAXY A9 2018(SM A920F), TWRP OF SAMSUNG A8 STAR , ERRONEOUS PORTED TWRP FOR A920F 2018 FROM A8 STAR , AND , LOGS OF MY PORTED RECOVERY ARE AVAILABLE AT THE LINK POSTED AT THE END.

I downloaded twrp of samsung a8 star 2018 as it has almost same specifications as my device samsung galaxy a9 2018(sm-a920f) . I ported the twrp from the a8 star 2018 model to a9 2018 model. After i ported twrp manually, using guides available on Internet, I booted into the ported twrp successfully and it displayed it interface. But some minor issues are to be fixed to make it fully functional . I need your help in this part pls.

2 conclusions are:

1)the touch was not working when I flashed a8 star's original twrp without porting. But still I was able to enter the twrp and I saw the interface but I couldn't interact with it as touch didnt work.

2) after porting the a8 star's original twrp, touch started working and the issues persisting are the following:
i)most mount points are wrong ( a picture of log is available at the link I have left at the end

ii)opening terminal only displays a blank black screen

iii)I can't select many partitions when I tap on backup (possibly caused by wrong or incomplete mount points)

iv) I can't change brightness in twrp even though I swipe the slider to extreme left for lowest brightness

v)size of internal storage and sd card is showing as zero( possible due to incorrect and incomplete mount points)

vi)I can't access internal storage and sd card through file manager of twrp(also caused possibly by erroneous mount points)

get the correct mount points for various partitions from stock recovery ramdisk/etc/recovery.fstab
replace the mount point values in twrp ramdisk/etc/*fstab

Note
you should keep twrp fstab's structure
you can delete any partition's line from twrp fstab that doesn't exist in stock recovery fstab and you can add those that exist in stock recovery fstab

userdata and internal storage ; see https://www.hovatek.com/forum/thread-30160.html

external sd, you can try the mount point below
Code:

/external_sd      vfat     /dev/block/mmcblk1p1  /dev/block/mmcblk1            flags=display="external_sd";storage;wipeingui;removable;fsflags="utf8"

I can't access internal storage,SD card, or data partition in TWRP after I ported it from other phone. It started to show the available size instead of the 0 mb error when I flashed force disabler DM verity zip to data partion using ex kernel manager APK, after that system seems a little scrambled. But still I can't access the folders in TWRP. TWRP is saying permission denied.

also attach the fstab from stock recovery and if possible the fstab from the port twrp you used
