Galaxy Tab S SM-800 stuck with flashing TWRP logo

I was provided this device to try and help resolve the issue. I am not sure how it got to this point. I believe that it was rooted with a custom ROM, then the individual tried to install a stock ROM (method unknown).
The current situation is:
Galaxy Tab S 10.5 SM-T800 stuck in a bootloop with the TWRP logo on the screen. I can not get the tablet to go into download mode. I have tried all of the different methods to enter download mode, i.e. Power & Vol - & Home, Drain the battery > Plug into PC while holding Vol - & Home, Power & Vol + & Vol -. None of these combinations do anything. The only thing I can do to get a response is to press Power & Vol +, which reboots the device right back into the TWRP loop after the Samsung Logo. Power button alone does nothing.
The device is seen by Windows with the Samsung Drivers but is not mounted to a drive letter, and I can not mount it.
ADB , fastboot and Odin do not see the device.
I would like to flash a new rom either custom or stock, but I need to be able to get the device into download mode so it can be seen by odin.
Any help would be great.

Probably just timing and pilot error this one. I've never known of any Samsung device boot but be incapable of booting to download mode as download mode is bootloader related.
No working bootloader means dead device.
No matter what state the device is in at the moment with the usb cable removed, hold POWER + VOL DOWN (not up) + HOME until the Samsung boot logo comes up, hold for another couple of seconds then release. Download mode should appear.
I know it should be easy....
I know it should work but it is not, I will make a vid of the process and post. I can not make heads or tails.

Is the home button actually working, are you pressing it firm enough?
If the home button doesn't register then the tablet will simply reboot.
Its a bit odd why twrp doesn't fully boot though unless it's the wrong one.
Does it hang at the twrp logo or continually reboot?

S20 ultra cannot enter download / bootloader mode

Hi folks
Anyone seen this issue before (see pic) ?
When I try to enter download / bootloader mode I get stuck on red text 'entering fastboot mode... ".
Odin cannot detect the phone connected to PC
The only way out is to press and hold power and volume down for 5 seconds to reboot normally
Tried factory reset and also tried clear data & clear cache partitions in recovery mode.
FYI I'm on O2 UK branded July 2020 stock firmware
With this steps the problem will be solved:
Power Off
Insert cable on pc
Press Vol Up + Vol Down
Insert cable on phone without releasing the buttons
But I agree, the 'old' method does not work anymore, I am getting the same message as the OP.

Is this a very recent change by Samsung? I ran various Google searches but could not find any relevant article on the web or on xda forums

Samsung S20+ Magisk uninstall bootloop.

I followed this guide to get my S20+ rooted: https://forum.xda-developers.com/t/...root-s20-series-and-upgrade-firmware.4079353/
I wanted to return my phone to it's original state so I tried uninstalling Magisk through the app but am now stuck in a bootloop where I can't seem to enter recovery or download mode.
The screen pops up and shows the logo, followed by the bootloader unlocked warning, back to the logo, and then restarts this process.
I can't seem to turn it off either. Have to wait for it to be 0%, but once I connect it to a charger, it automatically turns on again.
Can anyone help me solve this problem?
Recovery mode: volume up button and plug it into PC via cable, press power
Download mode: both volume buttons and plug it into PC via cable, press power
both modes only work if you have a cable connected
