[Other] Event After Elite 4

[impsycho12]

I have an issue, I can't seem to make an event only appear after beating the Elite 4.
I tried many checkflags, but none of them would compile to the game for various reasons.

This is the normal event (without appear only after beating the elite 4)

#org 0x740001
special 0x187
compare LASTRESULT 0x2
if 0x1
goto 0x81A7AE0
special 0x188
lock
faceplayer
checksound
cry 0xFB 0x2
waitcry
pause 0x14
playsong 0x0 0x2
setwildbattle 0xFB 0x5 0x0
setflag 0x807
special 0x138
waitstate
clearflag 0x807
special2 LASTRESULT 0xB4
compare LASTRESULT 0x1
if 0x1
goto 0x8162558
compare LASTRESULT 0x4
if 0x1
goto 0x8162561
compare LASTRESULT 0x5 if 0x1
goto 0x8162561
setflag 0x250
release
end

'---------------
#org 0x1A7AE0
release
end

#org 0x162558
setflag 0x2BC
goto 0x81A922D

#org 0x162561
setvar 0x8004 0x96
goto 0x81A9236

#org 0x1A922D

fadescreen 0x0
release
end

'---------------
#org 0x1A9236
fadescreen 0x1
hidesprite LASTTALKED
fadescreen 0x0
bufferpokemon 0x0 0x8004
msgbox 0x81A63C4 MSG_KEEPOPEN '"The [buffer1] flew away!"
release
end

'--------- ' Strings '---------
#org 0x1A63C4 = The [buffer1] flew away!"

How would I make it so it would only appear after beating the Elite 4?

Did you try checkflag 0x82C?

Did you try checkflag 0x82C?

I did but I might've been doing it wrong. Could you show me how i'd put in my script?
