S8+ wont turn on after flashing bootloader

[tonycstech]

I flashed bootloader according to instructions on https://forum.xda-developers.com/galaxy-s8+/development/root-t4128321 in an attempt to root.
Now my phone wont turn on at all.
Even removing battery has no effect.
No vibrate, no flicker, no LED lights, nothing.

Flashing was completed and phone rebooted and that was it. No sign of life since.
I dont know what to do.

Is there a way to flash stock bootloader on to the chip manually with some kind of hardware and a utility patching directly to the board ?

I have not looked at it yet but am sure there is a way to tap in, i just need to know where.

Same here, Is your phone ok now?

My booloader version was b8, and it seem competely bricked, no response whatever I do.
I try to saving it by using 9008 mode but I can't find b8 stuffs.
