Root your phone and flash this through magisk https://github.com/blackeangel/UKA/relea...k_sign.zip and use install termux and mt manager,after reboot ,now push your payload.bin into data/local/unpackerpayload folder
And type su in termux and hit enter and type menu and also hit enter and choose 11 which is other tools select extract from payload
I did not find in the description how to rebuild the payload.bin, I only see an opportunity to unpack the payload.bin, I need an unpacked payload.bin to pack back after modification of boot.img
