No point going through all that if your board already has the pads for C1.

Mine doesn't.

Guys this topic is a duplicate. Here is very interesting discussion and finding on this

This is 46 pages long now but worth reading.

Currently adding the capacitor helps only sometimes! So there is no easy DIY fix for this.

It has helped every time I have installed C1. How many C1 installs have you done?

C1 is the fix for this issue.

When there is a problem, admit it as soon as possible.
