How to install OS in Samsung smg531f which is without OS?

Question

I have a samsung SMG531f Grand Prime. I accidentially deleted my OS in Team Win by selecting the System option coming under Wipe option in the main menu. Now when I switch on the phone it will show only the startup screen. I can only go to the TeamWin by pressing Volume up Home and power button. But when I try to go to odin mode by clicking on volume down power and home button it doesn't work. How can I overcome this problem and reinstall os to this phone.

Volume up key doesn't work in this phone.

Prefer a solution which can be configured in Windows environment as I don't have access to an open source OS.

1. download and extract ROM from samloader

   cd /media/xubuntu/1234567890ABCDEF
   sudo apt update
   sudo apt install android-sdk-ext4-utils android-sdk-libsparse-utils android-sdk-platform-tools-common android-tools-adb android-tools-fastboot f2fs-tools git python3.8 python3-pip
   
   git clone https://github.com/nlscc/samloader
   
   cd samloader
   pip3 install .
   cd ..
   sudo cp -av ~/.local/bin/samloader /usr/local/bin
   
   mkdir Android
   cd Android
   
   samloader -m SM-G531F -r SLK checkupdate
   samloader -m SM-G531F -r SLK download -v G531FDDU1APJ2/G531FODD1APJ2/G531FDDU1APJ2/G531FDDU1APJ2 -O .
   samloader -m SM-G531F -r SLK decrypt -v G531FDDU1APJ2/G531FODD1APJ2/G531FDDU1APJ2/G531FDDU1APJ2 -V 4 -i SM-G531F_1_20161116150254_w0xdzpk60j_fac.zip.enc4 -o SM-G531F_1_20161116150254_w0xdzpk60j_fac.zip
   
   unzip SM-G531F*.zip
   tar -vxf AP_G531F*.tar*
   

2. convert system.img into mountable disk image

   mv -v system.img system.sparse.img
   file system.sparse.img
   simg2img system.sparse.img system.img
   file system.img
   

   (optional) check if mountable

   mkdir system
   sudo mount -vo loop,ro,noexec,noload,noatime -t ext4 system.img system
   ls -a system
   sudo umount -v system
   

3. copy file to MicroSD Card

   adb push system.img /external_sd
   

   (optional) compare digest

   md5sum system.img
   adb shell md5sum /external_sd/system.img
   

4. write disk image from terminal dd

   adb shell
   find /dev/block -name by-name
   ls -l /dev/block/bootdevice/by-name/system
   dd if=/external_sd/system.img of=/dev/block/bootdevice/by-name/system
   reboot recovery
   

5. disable dm-verity and recovery-from-boot.p (necessary for TWRP)

   adb disable-verity
   adb shell
   mount -w /system
   mv -v /system/recovery-from-boot.p /system/recovery-from-boot.bak
