Yesterday, the earphone jack on my 2-year old TinySA detached from the PCB. The jack's footprint has three pads, two of which are connected by a very fine trace (fig. 1) and one of the two connected pads is missing.
?

I did not attempt to join back the missing pad because soldering a fine wire on the broken trace is beyond my dexterity. Fortunately, the jack's 3 solder terminals are replicated on the top of its body (fig 2). So, I replicated the missing connection by soldering a fine wire between the 2 top terminals.?

Then I soldered back the other two terminals to their respective PCB pads. I would prefer to mechanically secure the jack by tying it down to the PCB using either cable tie or twisted wire, but cannot do so because the LCD on the opposite side prevents me from drilling holes (fig. 3).
?
?
?
So, I ended up slathering epoxy glue on the jack and PCB (fig. 4).
?
To prevent the jury rigged jack from detaching again in the future, I resort to permanently leave a pigtail connected to it (fig. 5).

Feedback welcome!
