rooting – Samsung Galaxy Tab E SM-T560 bricked

Recently, I tried to root my Samsung Galaxy Tab E T-560 and I was unsuccessful. This is the first device I tried to root so I do not have much knowledge about this topic. I decided to root the tablet because the tablet stuck on Android 4.4 and I cannot launch many apps from the Play store.

I followed one tutorial which was specifically for this tablet. First I installed USB Drivers on my notebook, installed software Odin3 v3.14.4, and downloaded Samsung Auto-Root pack and unpacked files.

On the tablet, I opened Settings, enabled Developer settings, and turned on OEM LOCK. Then I opened the Odin software and with the AP button, I selected a file with .md5 extension (CF-Auto-Root-s5neolte-s5neoltex-smg903f.tar.md5). Next, I turned my tablet into download mode and connect it to my notebook with a USB cable. Last, I pressed the Start button, and after some time rooting failed.

Now my device is bricked and it stuck on the screen with the message:

“Firmware upgrade encountered an issue. Please select recovery mode in
Kies & try again.”

Can someone please tell me if I can unbrick my device and what I did wrong? I suppose that I chose the wrong .md5 file but unfortunately, I believed what the tutorial says.
