Remove the CMOS cell and connect power.

I was take out the CMOS(battery) , connected the core, turn in on, but the same stuck at apple logo, I was also tried to do internal recovery but it was struck on 99% loading

Try to install original macOS version; start with SHIFT + OPTION + COMMAND + R.

Check if is possible to install Windows, or Linux.
Or test with some Live version, at least.
