Android os is gone!

[AC Question]

Hi there,
When i tryed to root my tablet (SM-T320) i was useing odin and a tar.md5 file which was a custom rom with root, when i was flashing it on to my tablet it began gliching after "reboot" and the word 'pass' didn't appear on odin. I unpluged my tablet and then pass appeared.

Now my tablet constantly reboots, i see the following tekst (the first line appears in blue the sencond in red and the third one in yellow):
'recovery booting..
recovery is not seandroid enforcing
set warranty bit: recovery'

This tekst is displayed for about 0.25 seconds and then is see the model name and above it a banner of mainly white and a bit of some other coloured pixels.
It stays doing this the whole time.
things i already tryed:
- take out the battery, put it back and reboot (doesn't work)
- system format (doesn't work either)
- going to download mode (same)
- going into recovery (again same)
the last two are actualy also part of the android system so android is literaly erased from my device or at least the software could be broken.

Odin doens't find the device anymore, nor my pc does.
Is there any way i can still restore it myself? or do i need to send it to samsung to repair?

If you accidentally deleted the OS, your device is bricked. It is possible to fix, but you'd need to be fairly savvy to use something like a jtag to restore the stock firmware. I'd send it in for repair, but Samsung may refuse for tampering with the device which breaks warranty.
