Ok, thanks for the infoHi, as the image clearly shows you haven’t even unlocked your bootloader yet so obviously you can’t flash anything till unlock it first. Own lock is on so you need to enable Dev options, enable usb debugging and oem unlock,then before getting into download mode where it ask you to continue or cancel there’s an option to press and hold Bol up for the 3 step of BL unlock. It’ll ask are you Sure and when you click on or whatever the menu says for okay. Your entire data will be wipe so take a backup. Your phone is a Qualcomm snapdragon device so confirm different as they probably are.
Get the TWRP official recovery that is available for snapdragon variants and is supported as it is official.
Hope this helps

Maybe exynos but not the same chipset haven’t you noticed your device model number isn’t the same series I mean it is N970 for note ten, N975 for note10 plus, N976 for 10+ with G.
Yours is probably an exynos chipset that is the exynos version of a Qualcomm 7 series chipset.
