Coreelec in Amlogic X96 max Plus S905X3

Hello, i just purchased my x96 max plus and tried installing from usb the Coreelec. I followed all the steps indicated but my device keeps rebooting while i have the reset button pressed (toothpick method). Same thing happens when i also use the Terminal Emulator android app. I followed instructions from here How to install CoreELEC and seen some youtube videos. I also used the sm1_s905x3_4g.dtb file but this didn’t work either.
I don’t have an SD card available right now. Any reason why this doesn’t work? I used the latest coreelec version (CoreELEC-Amlogic-ng.arm-19.1-Matrix-Generic.img)
