Sup guys, i recently purchased an imac from ebay that was supposed to work but the seller scammed me and sold me a mac that was firmware locked. 2 months of headaches and learning, i was able to get the bios chip out without damaging the computer . Is this firmware impossible to bypass, and if not, how can i clean it so that the firmware password gets removed?

Re: 2019 iMac 21.5''
Open the bios with a hex editor and search for $SVS ,then fill the region you select with FF`s . There are lots of videos on youtube showing how its done https://www.youtube.com/watch?v=KCl6Iu8fSSI

by jprezaHey guys,
Looking for schematics for an iMac 4k 2019 model. For the life of me, I can't figure out why the display will not work.Everything is connected correctly, I don't see any caps or resistors that are damaged. I even swapped the display from another iMac 4k 2019 model to test it, and that display won't work either.
There are 5 diagnostic LEDs and only 4 light up. The last one does not.
Any help with schematics would be awesome!
