Royal pain in the butt: can you fix a micro usb female fitted in a phone/tablet?

:palm:
It's a regular tablet so there's no immediate guess that it has a discrete module to remove for it. You think it's worth taking it apart and trying to solder something new into it that sticks out or something?
I don't have any special microsoldering equipment but I have a TS100 and good lead solder.

Hi!
Yes. It is worth to change and it is easy.
You must have:
- a regular soldering iron
- a good soldering wire
- goid and lot flux
Try search on YT for some advice how-to, just to get an idea...

Not too difficult if you have a hot-air station. A 50$-delivered from Banggood will do nicely. For soldering the replacement, your TS100 will do, maybe even without extra flux, but the removal of the broken one is a bit of a pain do to with just an iron and nothing else. You can try wicking, go for a desoldering wick that is presoaked with flux. The main pain point will be the mechanical joints, not the contacts.
Good luck and try not to lift any pads ;)

Generally, when removing parts without using hot air, damage to one part can be mitigated by sacrificing the other. For example, a damaged part is of no use, so carefully cutting it off, leaving just the pins on the PCB pads will ease the stress on the PCB - you simply wipe those pads clean, and use a solder sucker for any solder filled holes.
I'm not suggesting using wire cutters (which can easily tear off the pads), just that, you don't have to be overly gentle, you want to do the least damage/heating cycles to the PCB as possible. Constant heating and re-heating of the same area can cause pads/traces to permenantly lift, or through-holes/via to be pulled out. This can be a nightmare to repair with today's multilayered boards.
If you don't have temperature controlled hot air, then I would first cut any through-hole mounting lugs on the USB socket, then flood the USB pads with solder and flux so they can all be heated at the same time. Clean up with solder wick, and put the new one on.

One thing to consider: Qi chargers are dirt cheap (£5 or less), provided you have the NFC/Qi charging capability, of course.
Perhaps you need a USB port for other things, but is it worth the risk of damaging the device further by trying to fix it, if you have a fallback option?
