iMac won't boot past Apple logo in any way
One day my 2019 iMac was just on standby when it just shut down, and it was never able to boot back into anything. The Logo shows up and the progress bar goes to 60% and restarts, then it gives me the message that “My computer restarted because of a problem” and restarts, then just giving me a loading bar which goes to 60%. It then reboots again through this cycle until about 5 minutes later when it gives a prohibitory symbol and shuts off. I have tried everything, including
Recovery Mode, where the bar becomes slower but still reboots anyway
Internet recovery, where it the progress bar under the globe finishes but then fails to boot after
Booting off an install usb, where I still cannot get in
Safe mode, where the issue still persists
Smc reset and Pram reset which both did nothing
Single user mode where the cpu and macos version is being detected correctly,
Reseated all the ram and checked one by one (nothing changed)
Mac hardware test where it passed (?????)
And after all of that I still cannot boot into anything. Curiously it still manages to still powered on during single user mode and the disk selection screen, leading me to believe this is not a cpu issue.
Has anyone had a similar experience?
Also, I could only find my exact problem on this post: https://discussions.apple.com/thread/822...
Esta é uma boa pergunta?

What is your drive config a HDD (platter) or SSD (blade) or Fusion Drive setup?
You might want to see if you can boot up under the Startup Manager pressing the Option (⌥) key. Then use the keyboard error keys tl select your boot volume. Let us know if that worked.
Reference: Mac startup key combinations
