Thank you for those images. that is the basic information I asked for; it tells us that you will not be able to flash anything at all except a Samsung Official binary till Prenormal is lifted.
You are at the Preinstall Instructions (and cannot move on). The target now is to have the Prenormal barrier lifted to “Checking”. Please be aware to keep checking for that clue on the device.
First of all this is a device “Built for Android 9” where you propose to install Android R using Install /e/ on a Samsung Galaxy Tab S5e (Wi-Fi) - “gts4lvwifi”.
Please can you tell me the version of Android is running at present.
My “Know your hardware” article gives some clues to the many reasons Prenormal might exist. Half the problem is to find out what hurdle you have to meet.
If the phone brand is new or refurbished “like new” you may have to use it “normally” for 7 days with a SIM and wifi. This is mentioned by @trashHeap as a blocker in the third link I already gave you.
With the device powered off - hold Volume Up + Power.
With the device powered off - plug in the device while holding Volume up + Volume Down + Power.
The clue here is “plug in the device”. The physical connection of the USB cable is being used as a trigger of some sort. Any time you see a comment about what you are to do with your USB cable it is likely to be vital that you follow the exact sequence you are given.
As I do not have personal experience of this device, I am not going to tell you what to do, just point you to the material that has the clues you need! The second link points to 12 user experiences, one or two of which might be relevant to you; the third link is vital reading - Document Suggestions contains any user feedback where the successful installer kindly left clues for those who follow.
When you mention bypass method are you referring to the Corsicanu RMM/KG bypass? Notice that cannot be used beyond Pie.
Your Odin mode image does not go right to the margin ! So that you get all the clues and can tell for certain if something changes, it might be helpful to write down here exactly what you see in this format (correcting what I cannot see !):
xxP LOCK : OFF
xxM LOCK : OFF (U)
XXX State: PRENORMAL
WARRANTY VOID : 0x0
Post script As well as asking whether the phone was new, with regards to the possibility of a simple Region lock, I should have asked if you got it through a regular retail channel or whether there is any possibility the phone was not sold in its intended market? This is often seen in devices imported to USA !
