Easy Installer problems

Problem 1 ) My easy installer checksum SHA256 dont match when i down the file.

Problem 2) I used the Easy installer on my unlocked Oneplus7T and followed instuctions. It got to the step to unlock bootloader and download all files and reboot. BUT WHEN I GOT TO RECOVERY MODE- NOTHING AT ALL —> It just keeps rebooting to the same START screen to select recovery mode.

It looks like phone is bricked now lol
