If you installed stock via ODIN, it should boot. Did you try to reboot to recovery (stock recovery)?
If not yet, do that after flashing stock. Then format/wipe data and then boot to recovery. No need to mount /system, as it gets auto mounted.

You may have to flash the stock ROM again. You did use the boot.img method correct?

Okay, go to recovery, wipe data and wipe cache. Mount /system.

Also, before that, copy the log to your system or share images, if unablet to copy. Need to see. Meanwhile retry stock image. Ideally you should not face this. If need be uncheck the auto reboot, and once stock is flashed, reboot to recovery and wipe data and then reboot.

Cross check your files you are using.

No worries.
Mount /system option is available in your stock recovery. To go to recovery from the download mode press volume down and power button, then once you feel the vibration, keep pressing power button and switch to volume up button. Keep it pressed for 2-3 seconds and th3n let go of power button. You will see android logo and Samsung stock recovery will come up. In that first wipe data and cache, and then Mount system option. Then click on reboot to bootloader/download mode. Then flash the stock ROM. Uncheck auto reboot. Post flashing shows success, go back to stock recovery and wipe data. Then reboot to system/reboot from there.

Logs, ignore. If you are doing the above, you will boot to system, no matter what. Unless you have a specific hardware issue then online no one can help and you will have to go to service center.

Have you ever flashed a ROM and ever been to any stock recovery?
Turn off phone. Press volume up and power button together and wait for recovery to show up..

I have entered recovery mode and wipe the cache. Bit still the same issue.
Can we solve this with logs ?
I saw one option recovery mode that os recovery logs. Will it help?

Wipe the data too. Yes please copy the logs. The logs option will give that. BTW, are you sure you are using the right OS file? There is no other reason why you cannot boot. Booting stock will take minimum 15 minutes.
