So my wife soaked her HTC U Ultra phone paddle boarding in a river. We have the phone but it won't charge. The plug sparks and gets super hot really fast, probably shorted.
We tried cleaning it with some electronics alcohol spray used for removing flux, but no such luck.
So I broke into the back of it (shattering a thin layer of glass, wow!) And started disconnecting things trying to pull it up.
We knew the battery was dead because of being shorted, and the dead USB C connector wouldn't let us charge... so I found the test pads on the PCB for the battery and soldered on some jumpers.
Hoping it would come up I used a 3.7v 1S LiPo hobby charger to see if it would power up with a charge.
It worked!
She was able to use the Files app to xfer to an sdcard and saved her pictures of he trip to Orcas Island!

So I managed to snap one of the micro usb port pins out of the socket from my phone. I was in a rush, phone plugged in, grabbed the phone (at an angle), and yanked the charging cable off.
I noticed the next day it wasn't charging when i plugged it in. On further inspection, I could see one of the pins was bent/broken in the charging port. I can wiggle it to get it to charge, but it's annoying as hell. I've been using my wall charger, but i really need to fix this because I use the GPS a lot in the car.
LONG STORY SHORT
Took the phone apart to see if I could replace the micro usb port. I can. I'm just not sure which type of micro-b to buy. Can anyone point me to a product/link which sells the part I need based on the photos below? I'm comfortable soldering.
Phone:
Chinese Star N920e (awesome phone btw).
Thanks for any help.

Wow, that's what I figured. I knew that a $35 (once was) qi case couldn't be that fancy.
Makes me wonder if someone could fab something up from a metal face and soldered contact wires to the Qi connections?
As you know, the original 1020 qi case goes for $120. I was thinking of either getting a 925 qi case for $12 or fabbing up some sort of coil and contact pins of my own.
Thoughts?
Already done that , works like a charm here is example of mine , bought cheap 4$ receiver from china disassemble it took coil and that what came out , works like a charm
I received Wireless Charger Pad-YCCTEAM

Charger look so cool. Blue light. 3 coil for charging.
I try with case and phone was charging. With none problem.
The workmanship of the charger is good. The only minor problem is the speed of filling that noticeable after a long time used a quick charger.
No need position phone on some specific place.
Cable is 1m.
When phone is charg, i dont hear anything.
Blue light is not strong and in dark of the room i cant see on wall or any other place. Just the charger light.
Size is 10.8*62*122mm
There are non-slip pads on the top and on the bottom to keep the charger and your phone from easily sliding off.

I like tht. I hve a reg smsung pearl wirelezs pad. It works good for my s6. But my lg g4 is touchy and that looks like it will accomodate it well
This poor guy had been collecting dust for the last five years due to his frustrating 4 hour battery life. Eventually it would even uncharge while it was plugged in to the wall with the display at minimum brightness, bluetooth and such disabled.
Be careful as I believe Nexus 9's have only been evaluated up to 1.5A. I have it plugged into a circuit breaker just in case (and have wrapped red electric tape near the tip to distinguish it from my other micro usb chargers. I'm quite sure if it would melt, although the regulator on the charger cord looks pretty legit, so who knows. Some Nexuses are older than others, mines gotten quite a lot of use so when I use this charger it doesn't even run warm let alone hot.

Hi, I would like to ask if the thin tracks/pads are essential to powering up the phone? I'm guessing they are temp sense and something else?
Backstory: my phone had saltwater entering the case after the adhesives went loose. The battery connector burnt out and the thin track/pads got ripped off.
My goal is to try to power up the device long enough to recover my data.
The photo below shows the current state of the board. I can cover the exposed copper with epoxy, but will have trouble soldering onto the exposed copper vias (the dots) that were orginally below the pads. Picture shows some solder on the copper vias but it doesn't work as well as having pads. The battery connector component is a new one, and I have gotten a new battery as well.

Questions
1) Are the thin tracks/pads are essential to powering up the phone?
2) Can I just power up the phone with just the main 4 pads?
Many thanks.
