Samsung Tab S3 Stuck in bootloop

[Members_SWffEWs]

Hey, my Galaxy Tab S3 T820 has started bootlooping. I can't enter recovery mode (when I try to show "recovery Booting ...") but it does manage to enter download mode. I replaced the battery and the bezel with the power button, but that didn't help either. Someone could help me what can I do?

@Members_SWffEWs, The best you can do in this situation is visit Samsung service center. Probably motherboard need to be replaced if reflashing firmware didn't helped.
