I have done a few surface mount repairs, and I have a tiny Oryx 6-watt iron and some tweezers :)
But I can't locate the videos you refer to. I've tried searching on Youtube for every combination of nanoVNA and rf input, burnout, etc.
In the meantime I have ordered the same model H4 (with excellent reviews) from Aliexpress again, $61 with tax and shipping.
