Keep restarting with scrambled screen, recovery and download working

I have got friends phone that keeps restarting, after Samsung logo it does show random pixels.

I can get into Recovery, everything is displayed properly

and also into download mode.

I did try to flash exactly same ROM by Odin, but it just flickered "Erasing"

and screen got scrambled again.

Any ideas what could be wrong? Oh, I forgot to mention that I did flash BTU ROM but recover still showing EUX.

I guess this is MediaTek mode
