I have 2012 Macbook Pro 15" Retina. One of the speakers blew and I was about to replace but after I opened the back I decided it was too much trouble so I just disconnected the side that was broken
Then when I tried to reboot I got stuck on the screen with loading bar
I tried doing all the keyboard resets and it didn't help
Then I tried making making a boot USB from OCLP using Monterey (the installed OS). I could boot into EFI and start the install but it never complete
Then I tried making a normal Success' href='/2020/12/install-macos-catalina-on-supported-pc.html'>Catalina USB boot disk using Apple's instructions. Install never finishes
Then I tried on an empty SSD and same thing
Not sure what to do now. The internet recovery gives a no internet error even when I am using USB adapter w ethernet cable
