Unable to Flash the Android OS on eMMC

Hello

I am using radxa zero 2 pro but I am unable to flash android os on my board.
I am able to use debain OS but not Android.
If I run the flash-all.bat file after all the process mentioned on official website. 1st part of system file fails & goes for 1st part of vendor and that also fails & later if i connect the board with HDMI Display it only shows the logo of A311D nothing else.
And sometimes the bootloader’s few parts are also failing.
I can attaching a txt document for the logs which i am getting when i run the flash-all.bat in my windows system.

Please let me know if anyone can solve this problem or I will shift to another board.
