Hello there, I try the following command, '-fastboot reboot bootloader' then it appear my phone to Download mode. After that I start re-flash with Odin, success back to Samsung A30s Android 11 stock rom. But it started normally back to normal. How can I root Android 11 in the right way. I had failure many times when I root with Magisk 23 and TWRP. Does Anyone here to give me a hint, please???

I tried several times to turn my phone to up again, with push volume button up + down with power button but only appear samsung logo and turn back off again and again. How can I restart back to Download mode so I can re-flash the stock rom again? Sorry I am newbie here.
