Is it safe to buzz out an antenna path? Those seem like they might be sensitive to DC if anything isn't actually shorted, or if testing for a short to ground.

I also thought about adding a micro antenna connector to the Raspberry Pi 4. But now after looking at your article I began to doubt. It is a pity that you did not succeed.

Dang - so close. It wasn't for a lack of trying, so kudos for that. At least you tried. When I attempt repairs on on others electronics, I always warn them that “it may get fixed; it may never work again” for this exact reason. A simple mistake could make it completely uneconomical to repair any further. Imagine bumping a BGA after you have heated a board up...

Bad luck. Impressive, you have the skills to make the repair attempt in the first place. Our company outsourced much of this work. You didn't by any chance work on a phase array bridge that connected antennas to a instrument landing system (ILS)?
