ALWAYS ALWAYS ALWAYS REMOVE THIS CABLE!!! Even if you are "only in there for a minute" tearing the connector off the board is EXTREMELY easy.

For anyone else looking at this, use solder braid to get the holes open. It's the best way to do it in nearly every circumstance.

Do yourself a favor and remove the display assembly from the computer first.

You do need to follow basically this whole procedure for a thermal paste replacement.

I second this.

Sorry about that, probably a blown fuse.

This is correct.

Some information in the top title area was misleading, as the iPod isn’t sold anymore (except for the touch with a soldered battery) and the iPhone has had a socketed battery since 2008. I fixed it in the latest unverified version.

Be VERY CAREFUL when removing this cable and also putting it back.

Reading through the guide, I have confirmed that this should work without adjustments for macOS Catalina down to Mac OS X Lion, as long as you create a USB flash drive correctly with the correct operating system on it.
