i was updating my imac, but i wanted to unplug something else which is in the way so i accidentally unplugged the imac mid way through the updates, now the Imac wont boot up, but i was possible to make the fan run full speed. But its still a black screen.

Ouch! Not good It depends on when you pulled the cord.
You’ll need to create a bootable external drive to see if it will boot under it. If it does then you have an out! Just restart the OS installer process again.
Now, if that doesn’t work you messed up the firmware update process which will require finding someone with the skills to fix the firmware or you’ll need to replace the logic board.
I would try visiting an Apple Store to see if they have some magic to recover the firmware.
这个答案有帮助吗？
The repair shop told me that they can't repair, it doesn’t work?
@lockxh - Well in that case its time for a new logic board ;-{
Can you tell us your exact system so we can point you to the needed part and guide as there are quite a few versions.
im not really sure about the specs because im not a nerd and i didnt go check the system
@lockxh - OK, we can work around that ;-}
On the bottom of your stand you'll find a label with your systems S/N, plug it into here EveryMac - Lookup.
Let us know what it told you.
OK great idea but i need to wait, remember that i said i sent the Imac to see if they can repair it? well its still at the shop and im in lockdown, i think maybe a few more weeks

@lockxh If you press the power button then immediately start holding Command+R, does it bring you to a screen that says "MacOS Utilities"?
