That's a good point. Although I was rather treating it as "once-for-all" solution, You never know. I think I'll re-think pros and cons again, after disassembling device, before applying.

When epoxy putty does eventually go "brittle" it will for sure break away and even crack under pressure and this is the reason we never use it in the trade for a permanent fix, we use epoxy putty to conceal components and is usually spread completely on top of the components hiding them from view.
IF anything does need repairing under these circumstances it is just not possible because to remove would be too difficult. There is an obvious point to make here and that is when the outer casing of the usb port which is metal and soldered down properly and the solder spread outwards as there is plenty of vacant painted green surface that can be scraped away to make a huge amount of soldering possible then it will never give, simple as that, unless you get a hammer to it or melt away the solder. Using links on a broken pcb will always stay in place because the port itself does not move if it has enough of a hold on the surface of the pcb.. |

hmm, you haven't got the point in my previous post, which been "not attach the USB receptacle to PCB at all, neither by solder nor by glue". So when "something breaks", all you need to do is get a new USB receptacle and place new putty around it, then solder it to the 6 stranded wires you attached to the PCB pads.
[edit] NB I'd even suggest to use a thin film of silicon oil to avoid the epoxy putty sticking to either the PCB or the plastic case bay. It shall be held by mere fitting in snugly into the bay, wouldn't even matter if it has a little bit of backlash as the stranded wires just bend slightly to cope with that [/edit] /j |

Interesting idea, joerg_rw. Ho ever, it requires first to someone get "broken" usb port with "clear", undamaged pads - not likely to happen, I'm afraid. But, if anyone got this (un)luck, it's definitelly a way to go.
For working USB ports, I would opt for soldering it to PCB. |

When my usb port broke off some of the data pads were damaged so i tried just re-soldering the power pins (1 & 5). That doesn't seem to have worked. I will try some other methods I read about here (thanks for the consolidated thread) but i'm curious why solderings pins 1 & 5 didn't restore charging.
When i connect the (unpowered) phone to a charger I get the usb icon and an amber charging light, but the light stops blinking after 4 or 5 blinks and doesn't charge the battery. Is that second ground pin, or some resistence on the data pins, required for charging? nvmd... read about data pins needing to be shorted for charging to work. |

Just bumping this thread since users here still have USB breaks.
