I mean no offence whatsoever, but not everything needs to have a YouTube video dedicated to it, let alone three. It looks to me like the ground wire for the bridge is missing, and replacing it was all that is needed. The lug under the pickup spring was never going to be a permanent fix, the screw through the bridge plate is better, but unnecessary.
I freely admit to overcomplicating things on a regular basis, but there's no reason to go to extremes when grounding a Telecaster bridge plate, soldering, brazing, bolting aren't necessary, just sandwich the bare ground wire between the body and the control plate. It's a time tested method.
Yet another hobby that is completely out of control...
