I recently bought a s3 to repair and resell.
The phone has 2issues
Broken digitizer
The usb port doesn't charge or is recognized by the pc.
Does anyone know how i replace the micro usb port?
What i know:
it's not connected via flex cable, is soldered to the board. so will need soldering
To replace i need a hot air blower, my soldering gun has that function.
Please tell me more

that's pretty much it. desolder the old one, solder a new one on there.
Does anyone have good resolution pictures of the usb port on the motherboard, so i could know what im getting myself into.

yes, use google. hope you're familiar with SMD soldering

Dear Glebun and other users,
I'm thinking of replacing the Micro USB port on my black GT-i9300. I've had charging issues some time now. First I had to some ' tricks' examples: Turning off, getting it to charge then turn on. Repeatedly jack the cable in and out. Rebooting and what not.
However now it wont charge at all. When plugged in to the wall socket it just stays at the level it is (when not using and screen off) when plugged in and using it the battery drains. Also my laptop won't reconize the device. (also won't charge when pluggen in the laptop).
I got this phone from my brother who has installed Cyanogenmod on it.
Now what kind of equipement do I need exactly? And do I need to work with some anti-static armband?
I am more interested in how you plan to fix the digitizer and make money on it?

Hello
I have a big problem with my Razr, my usb connector of my razr is broken.
I can not charge it anymore, it is not caused by usb cable because I tried with differents.
Someone know if we can buy new usb connector and replace it ?
Thanks you.

Is the connector on the phone "physically" broken, or does it just not charge?
It just doesn't charge.
But the connector is damaged for sure.
Just as a temp solution you Cern use battery charges (connecting their probes directly to the bat. + -)

I tried to do that yesterday but it didnt work.
I cut an usb cable and I put the red and black wires only on screw (
I did not have a screwdriver )

Hi! At first I wanted to say I didnt find any other thread which could solve my problem.
My battery stats doesnt work correctly. I mean, instead of battery status on my display I can see just a question mark.
But before everything I opened the phone to get to PCB and i scratched it near the antenna pins. Now I cant even charge my battery. It seems that the usb connecter doesnt work at all. However I dont think I broke the usb connecter when I opened my phone.
Do you know what could be the problem? Any advice?
Thank you!

If it is a hardware issue, why don't you take it to the repair services?

You're probably right and I should have done it alredy. Im just wonder if it's because of scratched pins that my USB port doesn't work. Thx anyway. : )
Hi,
I have a problem with my phone, and I think it's the micro-usb port
The problem is , I try to connect chargers, I tried a few already, and when I plug them, nothing happens, unless I play with the cable to a perfect position, but if I move the phone a bit, the charging stops.
is the corrosion on the micro usb? or is it because the port became wider and wider over time and the plug does not fit well?
if it's corrosion, can I use something like contact cleaner? or any way to solve that?
thanks all!
Best way is send for repair. If you've tried multiple cables its definitely the port. Best to replace the USB port

I have the same problem. Send to Sam and they actually change the entire motherboard for me.

Ok, im trying to figure out why this phone wont charge or connect to pc via usb. I have done testing on the port, and it appears the port is good. and it seems to be making good contact with the board. I have posted pics of the port and the area that connects to the board. I have checked the continuity from a cut usb cable i have, plugged it in port and have good continuity across all the pins of the port. My question is, are the pads on the other side of the pcb points for the usb port? becuase i have no continuity on any of the points with any pin in the cable. the phone turns on, i bought a brand new battery and screen for the phone, i got it for free from someone and it was completely shattered. I have about 75 dollars invested in it. It works perfectly, completely virgin no root or unlocked bootloader. Running the latest update.
I also posted a pic of the jtag pads, there is no continuity on any of those either to the USB. Nor any other pad on the board anywhere. And i think thats odd, there should be one somewhere.
Sorry if i posted this in the wrong area, mods can move it if they need to.

You try a diffent usb cable? I've tried some of the white ones and they never seem to connect to the pc.

Oh yea, ive done all the obvious things to try and figure it out. When i got it, they said it just quit charging, so i figured it was the battery, so i bought a brand new battery, which came charged, and a new screen, since it was shattered. It turns on, works perfectly, but it will no charge or connect to pc. ive tried 4 or 5 different cables, and ive wiggled and bent and pushed and pulled and everything else on them to try and get a sign of connectivity. So far ive come up with nothing.. This appears to be a common problem with this model, i guess i should have researched it more before i spent so much on parts for it.
Maybe the circuit board is fried.

As in the port lost connection to the board/broke? or this same situation, where it just quit working for no reason? The port is working as it should, and making good connection with the board. I'm stumped. If the port was broken, i could replace the port, no problem, but im 100% positive the port is not the issue here.

I didn't get into it as deep as you, but my phone would charge yet would not work over data (connected to pc). Repair store was stumped too.

Very interesting. I guess i will have to break down and buy another motherboard, i can get the whole phone on ebay for around $60 with broken screens. think thats my best bet.,

Did you figure out what happened to it? Mine suddenly developed a problem last week and would appear to be charging (charging light on) but it does not really charge. The port looks ok.
So I got this strange problem where my phone stopped charging. I tried diffrent cables, adapters, charging it while being off, charging it via the computer and even tried to adjust the little lip in the micro usb port. Is the charging board dead? If it is, will a replacement be expensive?

Well dude I think your assumption is right.
It might be the charging circuit only which may be dead.
Because as you told that you have tried diffrent cabels and chargers but still your charging is not working which means that the usb micro port through which we charge and connect our phone to computer is damaged and should be replaced .
There are many possible reason of damaging usb port like you may have drop your phone or by using faulty cabels and chargers or if u have rooted your phone then there is possibility of changing the voltage of current to more than 1000 Mhz etc etc.
You should try to flashed a complete stock rom by downloading from sammobile or directly using kies to update or re-flash your phone
you can try that may it may help you.

Nah, it won't turn on because the battery is empty.. I don't have a spare so it seems buying a new board is my only hope..
I saw there are loads of micro usb connectors on ebay. If I solder a new one on. Might that help?

You can try micro usb port which is available on ebay but it would be extremely very dangerous until and unless you know what you are doing.
My suggestion is to give your phone to the samsung care and tell then to repair it.
If your phone is in warranty then they will do it for free. You just need to provide them a copy of bill at the time you purchased s3.
Press THANKS if I helped you
