I have done this before but the result was the same

if can remove firmware protection u cant alive it, wait for supporters maybe they will spread some light

Make sure that the battery is connected to the board and charged.
At first glance, this is not important. But this nuance is crucial.

Thanks to all friends
My problem was solved by replacing the computer

using tetspoint load fastboot and flash ur desired firmware

that's exactly right
