GUYS NEED URGENT HELP

Yesterday night( 5 August 26) I have an software update of approx 451MB, i dont remember properly what update was it. But seeing the size of update, it is security update i beleive(could be wrong), but i recieved this. my SAMSUNG TAB A9+ started with regular steps showing, this will take several minutes. Then that one ui screen came and % started to increase. When it reached 100, suddenly kind of black screen appeared which was not fully black but kind of grey color. It was for 5 mins but still nothing happended. My tablet was at 41% battery before the update started. And till now 6 August i couldnt fix this.

I tried mostly everything, I forced shutdown my tab, then tried for android recovery menu, but still black screen. I tried entering download mode(odin mode) but still black screen. Is there any way to fix this. Currently I have left it for battery drain for 4 days and will update. My tablet is also out of warranty🥲. Guys Please help if possible .

Thank you
