OS Crash HiPad 10 XPro

My tablet HiPad 10 XPro start to crash after flashing, it start to appear only white with black stripe on middle. what should I do?

Did you complete the flashing correctly? did you install the correct files?

Can you make a picture of whats hapenning?

I follow the instructions I read from this forum because my brother put password and he forgot it so I came to this forum and follow some instructions same with my scenario. here’s the pictures

and the tablet became like this after fashing


I flashed the tablet because the tablet has no hard boot/reset even though I press any combination to activate hard reset
