Hello.
made a full backup of the firmware using a flash tool.

signed with cert 1 and cert 2.

if you delete them using a hex editor, the phone will not turn on, there will be a message:
"Red State
Your device has failed verification and may not work properly
Your device will boot in 5 seconds "

and it constantly reboots.

How can I solve this problem?

we don't have the tool or key that was used to make such signing
ofc you are aware that a key must have been used, anything else other than this key won't boot on the device
did you try unlocking the bootloader of the device before attempting to flash the modified files?
