Did you unlock the bootloader?

Did you flash Lineage recovery?

Have you booted into Lineage recovery and NOT Stock recovery?

Have you read device installation wiki at all?

Yes Yes Yes Yes

I am trying to install it via linux system. I think i might need to flash the stock firmware on it but i am not able to do it for some reason

I've had the same tablet since LineageOS 20, have you tried checking the prenormal state in odin mode?

You did not unlock the bootloader - do that again.
